技术领域technical field

本发明涉及通信技术领域，尤其涉及机器类型通讯的接入控制方法和设备及通信系统。The invention relates to the field of communication technology, in particular to an access control method and equipment for machine type communication and a communication system.

机器类型通讯(MTC，Machine Type Communications)指的是一个或者多个网元之间在不需要人为参与的情况下进行的网络通讯，例如交通控制与管理、远程抄表、远程监控、移动支付、定位跟踪、医疗监护等应用。Machine Type Communications (MTC, Machine Type Communications) refers to the network communication between one or more network elements without human participation, such as traffic control and management, remote meter reading, remote monitoring, mobile payment, Location tracking, medical monitoring and other applications.

The huge number of terminals is a huge challenge to the wireless communication network, and the wireless communication network is required to be scalable to adapt to the huge number of terminals and related new requirements. .

在第三代合作项目(3GPP，3rd Generation Partnership Project)通信系统中，终端在网络附着、位置更新、业务发起等情况下都会与3GPP通信系统的核心网交互信令。在引入MTC业务的场景下，大量的MTC终端可能会经由不同的接入网节点向同一个核心网结点发起信令交互，造成该核心网结点的负载过重，导致信令拥塞。In the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) communication system, the terminal will exchange signaling with the core network of the 3GPP communication system under the conditions of network attachment, location update, and service initiation. In the scenario where the MTC service is introduced, a large number of MTC terminals may initiate signaling interaction to the same core network node via different access network nodes, causing the core network node to be overloaded and causing signaling congestion.

首先说明的是，本发明实施例所指的接入网设备在不同的网络中可能具有不同的名称和位置，本发明实施例的接入网设备例如可以指：演进通用移动通信系统(UMTS，Universal Mobile Telecommunications System)陆地无线接入网(E-UTRAN，Evolved UMTS Territorial Radio Access Network)中的演进基站(eNodeB)、家庭基站(HeNB)或其它类型的基站；或，UMTS陆地无线接入网(UTRAN，UMTS Territorial Radio Access Network)/GSM EDGE无线接入网(GERAN，GSM EDGE Radio Access Network)中的基站控制器、或无线网络控制器(RNC，Radio Network Controller)等；非3GPP网络中接入网设备可指：无线局域网(WLAN，Wireless Local Area Network)中具有演进分组数据网关(ePDG，Evolved Packet Data Gateway)接入网逻辑功能的实体、微波存取全球互通(WiMAX，Worldwide Interoperability for Microwave Access)网络中的接入服务网络基站(ASN BS，Access Service Network Base Station)、或宽带码分多址(CDMA，Code Division Multiple Access)网络中具有高速率分组数据接入网(HRPD AN，High Rate Packet Data Access Network)接入网逻辑功能的实体；或其它网络中实现接入网逻辑功能的实体。Firstly, it should be noted that the access network equipment referred to in the embodiments of the present invention may have different names and locations in different networks, and the access network equipment in the embodiments of the present invention may refer to, for example: Evolved Universal Mobile Telecommunications System (UMTS, Evolved base station (eNodeB), home base station (HeNB) or other types of base stations in Universal Mobile Telecommunications System) terrestrial radio access network (E-UTRAN, Evolved UMTS Territorial Radio Access Network); or, UMTS terrestrial radio access network ( UTRAN, UMTS Territorial Radio Access Network)/GSM EDGE Radio Access Network (GERAN, GSM EDGE Radio Access Network) base station controller, or radio network controller (RNC, Radio Network Controller), etc.; non-3GPP network access Network equipment can refer to: entities in wireless local area network (WLAN, Wireless Local Area Network) with logical function of Evolved Packet Data Gateway (ePDG, Evolved Packet Data Gateway) access network, microwave access global interoperability (WiMAX, Worldwide Interoperability for Microwave Access ) access service network base station (ASN BS, Access Service Network Base Station), or broadband code division multiple access (CDMA, Code Division Multiple Access) network with high-speed packet data access network (HRPD AN, High Rate Packet Data Access Network) entities that implement the logical functions of the access network; or entities that implement the logical functions of the access network in other networks.

本发明实施例所指的移动性管理网元在不同的网络中可能具有不同的名称和位置，本发明实施例的移动性管理网元例如可指：与E-UTRAN连接的移动性管理实体(MME，Mobility Management Entity)、与UTRAN/GERAN连接的通用分组无线业务的服务节点(SGSN，Serving GPRS(General Packet RadioService)Support Node)；非3GPP网络中的接入网关(AGW，Access Gateway)WLAN中具有ePDG移动性管理逻辑功能的实体、、Wimax网络中的接入服务网络网关(ASN GW，Access Service Network Gateway)、CDMA网络中具有HRPDAN移动性管理逻辑功能的实体、或其它网络中实现移动性管理逻辑功能的实体。The mobility management network element referred to in the embodiment of the present invention may have different names and locations in different networks, and the mobility management network element in the embodiment of the present invention may refer to, for example: a mobility management entity ( MME, Mobility Management Entity), the serving node (SGSN, Serving GPRS (General Packet Radio Service) Support Node) of the general packet radio service connected to UTRAN/GERAN; the access gateway (AGW, Access Gateway) in the non-3GPP network WLAN Entities with ePDG mobility management logic functions, Access Service Network Gateway (ASN GW, Access Service Network Gateway) in Wimax networks, entities with HRPDAN mobility management logic functions in CDMA networks, or mobility in other networks An entity that manages logical functionality.

在如图1-a所示的系统架构演进(SAE，System Architecture Evolution)网络中，终端(例如普通用户终端或MTC终端)通过eNodeB接入到核心网的MME和服务网关(SGW，Serving Gateway)，并经过S-GW连接到分组数据网络网关(PGW，PDN(Packet Data Network)Gateway)。In the system architecture evolution (SAE, System Architecture Evolution) network shown in Figure 1-a, terminals (such as ordinary user terminals or MTC terminals) access the MME and Serving Gateway (SGW, Serving Gateway) of the core network through the eNodeB , and connect to the packet data network gateway (PGW, PDN (Packet Data Network) Gateway) through the S-GW.

在如图1-b所示的宽带码分多址接入(WCDMA，Wideband CDMA)通信系统中，终端经过基站(NodeB)到达RNC，再接入核心网的SGSN，并通过SGSN连接到GPRS的网关节点(GGSN，Gateway GPRS Support Node)。In the wideband code division multiple access (WCDMA, Wideband CDMA) communication system shown in Figure 1-b, the terminal reaches the RNC through the base station (NodeB), then accesses the SGSN of the core network, and connects to the GPRS through the SGSN Gateway node (GGSN, Gateway GPRS Support Node).

其中，WCDMA通信系统中的GGSN可对应于SAE网络的PGW，SGSN可对应于SAE网络中的(SGW+MME)。Wherein, the GGSN in the WCDMA communication system may correspond to the PGW of the SAE network, and the SGSN may correspond to (SGW+MME) in the SAE network.

本发明实施例中，将一个或多个MTC终端划分为一个MTC终端集合，并可以用集合标识(ID)来标识一个MTC终端集合。在实际应用中，可根据需要对MTC终端灵活的进行多种方式的集合划分，因此，MTC终端集合的集合标识也可以对应有多种形式。In the embodiment of the present invention, one or more MTC terminals are divided into an MTC terminal set, and a set identifier (ID) can be used to identify an MTC terminal set. In practical applications, the MTC terminals can be flexibly grouped in multiple ways according to needs, therefore, the set identification of the MTC terminal set can also correspond to various forms.

举例来说，可将相同业务类型的MTC终端划分为一个MTC终端集合，而集合标识则可为对应的业务类型标识；或者，可以将共用同一个国际移动用户识别码(IMSI，International Mobile Subscriber Identity)或者移动台国际ISDN号码(MSISDN，Mobile Station International ISDN Number)的MTC终端划分为一个MTC终端集合，而集合标识则可为对应的IMSI或MSISDN；或者，可以将使用同一个接入点名称(APN，Access Point Name)的MTC终端划分为一个MTC终端集合，而集合标识则可为对应的APN；或者，可以将访问同一个目的地址或访问某个特定目的地址的MTC终端划分为一个MTC终端集合，而集合标识则可为对应的目的地址；或者，也可以将某类特定签约数据的MTC终端(例如都用于智能抄表的多个MTC终端)、位于同一个地理区域(如同一个小区、同一基站辐射范围)的若干个MTC终端或特定的若干个MTC终端划分为一个MTC终端集合，而集合标识可为分配的特定集合标识；或者，也可以将所有的MTC终端划分为一个MTC终端集合，而集合标识则可为MTC终端的类型标识(MTC终端的类型标识可将MTC终端和其它设备(如普通用户终端)进行区别标识)，当然，也可以选择其它的集合划分方式，以满足不同的实际应用需要，此处不再一一赘述。For example, MTC terminals of the same service type can be divided into an MTC terminal set, and the set identifier can be the corresponding service type identifier; or, the same International Mobile Subscriber Identity (IMSI, International Mobile Subscriber Identity) can be shared ) or MTC terminals with Mobile Station International ISDN Number (MSISDN, Mobile Station International ISDN Number) are divided into an MTC terminal set, and the set identifier can be the corresponding IMSI or MSISDN; or, the same access point name ( APN, Access Point Name) MTC terminals are divided into an MTC terminal set, and the set identifier can be the corresponding APN; or, MTC terminals that access the same destination address or a specific destination address can be divided into an MTC terminal set, and the set identifier can be the corresponding destination address; or, MTC terminals of a certain type of subscription data (such as multiple MTC terminals all used for smart meter reading) can be located in the same geographical area (such as a cell , radiation range of the same base station) or a specific number of MTC terminals are divided into an MTC terminal set, and the set identifier can be a specific set identifier assigned; or, all MTC terminals can also be divided into an MTC terminal set, and the set identifier can be the type identifier of the MTC terminal (the type identifier of the MTC terminal can distinguish the MTC terminal from other equipment (such as a common user terminal)). Of course, other set division methods can also be selected to meet Different practical application needs will not be repeated here.

特别说明的是，在多种集合划分方式并存的情况下，某个MTC终端可能归属于一个MTC终端集合，也可以同时归属于多个MTC终端集合，当某个MTC终端归属于多个MTC终端集合时，亦可以利用多个集合标识来共同的标识该MTC终端所归属的MTC终端集合。In particular, in the case of multiple set division methods coexisting, a certain MTC terminal may belong to one MTC terminal set, or may belong to multiple MTC terminal sets at the same time. When a certain MTC terminal belongs to multiple MTC terminal sets During aggregation, multiple aggregation identifiers may also be used to jointly identify the MTC terminal aggregation to which the MTC terminal belongs.

在多数情况下，一个MTC终端集合包括多个MTC终端，本发明实施例中将对单个MTC终端的管理转化为对MTC终端集合的管理，有利于简化网络管理的相关操作。In most cases, a set of MTC terminals includes multiple MTC terminals. In the embodiment of the present invention, the management of a single MTC terminal is transformed into the management of a set of MTC terminals, which is beneficial to simplify related operations of network management.

下面通过多个实施例进行详细说明。The following describes in detail through multiple embodiments.

实施例一Embodiment one

本实施例主要从接入网设备的角度，描述本发明实施例的一种接入控制的实现方法。本发明实施例接入控制的实现方法的一个实施例可包括：接入网设备获取MTC终端集合的接入控制信息，上述MTC终端集合的接入控制信息包括：MTC终端集合的集合标识以及上述集合标识对应的接入控制指示；接收MTC终端在无线资源控制连接建立过程中发送的消息，上述消息携带上述MTC终端所属MTC终端集合的集合标识；根据上述消息携带的集合标识和上述MTC终端集合的接入控制信息，确定上述消息携带的集合标识对应的接入控制指示；按照确定出的上述消息携带的集合标识对应的接入控制指示对上述MTC终端进行接入控制。This embodiment mainly describes a method for implementing access control in an embodiment of the present invention from the perspective of an access network device.

The access network device acquires access control information of the MTC terminal set, wherein the access control information of the MTC terminal set includes: a set identifier of the MTC terminal set and an access control indication corresponding to the set identifier;

其中，接入网设备例如可以从移动性管理网元获取MTC终端集合的接入控制信息。Wherein, the access network device may acquire the access control information of the MTC terminal set from the mobility management network element, for example.

在一种应用场景下，移动性管理网元(以MME为例)可在发现自身的负载过重(超过某一设定阈值)时、或是发现PGW/SGW的负载过重时，或是需要对MTC集合进行接入时长或时段控制时，向接入网设备发送携带MTC终端集合(一个或多个)的接入控制信息的消息，将MTC终端集合的接入控制信息下发给接入网设备。例如，移动性管理网元可将MTC终端集合的接入控制信息携带在接口建立消息、配置更新消息、负载过重指示消息、专门定义的MTC终端集合控制消息或其它的消息中，以向基站下发该MTC终端集合的接入控制信息。In one application scenario, the mobility management network element (take MME as an example) can find that its own load is too heavy (exceeding a certain threshold), or when it finds that the load of PGW/SGW is too heavy, or When it is necessary to control the access duration or period of the MTC set, send a message carrying the access control information of the MTC terminal set (one or more) to the access network device, and send the access control information of the MTC terminal set to the access network device. network access equipment. For example, the mobility management network element can carry the access control information of the MTC terminal set in the interface establishment message, the configuration update message, the overload indication message, the specially defined MTC terminal set control message or other messages, so as to send the information to the base station Send the access control information of the MTC terminal set.

移动性管理网元可以通过从其它设备(例如可从PGW、网管系统、运营商数据库或其它实体)获取或自身生成的方式，获得第一MTC终端集合的接入控制信息。其中，第一MTC终端集合可以是根据业务类型、访问的目的地址、使用的APN、设备类型或其它特征属性划分成的；而第一MTC终端集合的集合标识可为：业务类型标识、APN、访问的目的地址、设备类型、分配的特定集合标识或其它的标识。可以理解，本实施例中的MTC终端集合可以包括一个或多个MTC终端，甚至所有的MTC终端(例如将所有MTC终端划分为一个MTC终端集合)。The mobility management network element may acquire the access control information of the first MTC terminal set by acquiring from other devices (for example, from the PGW, network management system, operator database or other entities) or generating by itself. Wherein, the first MTC terminal set can be divided according to the service type, the destination address of the visit, the APN used, the device type or other characteristic attributes; and the set identifier of the first MTC terminal set can be: service type identifier, APN, The destination address of the access, the device type, the assigned specific collective identifier or other identifiers. It can be understood that the MTC terminal set in this embodiment may include one or more MTC terminals, or even all MTC terminals (for example, all MTC terminals are divided into one MTC terminal set).

220、接入网设备接收MTC终端在无线资源控制连接建立过程中发送的消息，该消息携带上述MTC终端所属MTC终端集合的集合标识；220. The access network device receives a message sent by the MTC terminal during the establishment of the radio resource control connection, where the message carries the set identifier of the MTC terminal set to which the MTC terminal belongs;

其中，本实施例中的上述消息可为MTC终端在无线资源控制连接建立过程中发送的无线资源控制(RRC，Radio Resource Control)连接请求消息、RRC连接完成消息或其它消息。本实施例中接入网设备在MTC终端发起建立无线资源控制连接的过程，对该MTC终端进行接入控制。Wherein, the above-mentioned message in this embodiment may be a radio resource control (RRC, Radio Resource Control) connection request message, an RRC connection completion message or other messages sent by the MTC terminal during the establishment of the radio resource control connection. In this embodiment, the access network device initiates a process of establishing a radio resource control connection on the MTC terminal, and performs access control on the MTC terminal.

230、接入网设备根据上述消息携带的集合标识和上述MTC终端集合的接入控制信息，确定上述消息携带的集合标识对应的接入控制指示。230. The access network device determines an access control instruction corresponding to the aggregate identifier carried in the message according to the aggregate identifier carried in the message and the access control information of the MTC terminal aggregate.

240、接入网设备按照确定出的上述消息携带的集合标识对应的接入控制指示对上述MTC终端进行接入控制。240. The access network device performs access control on the MTC terminal according to the determined access control instruction corresponding to the aggregate identifier carried in the message.

在一种应用场景下，接入网设备可将移动性管理网元下发的MTC终端集合的接入控制信息进行存储。进一步的，移动性管理网元还可以向接入网设备下发MTC终端集合的接入控制信息的移动性管理网元适用范围指示信息，其中，该移动性管理网元适用范围指示信息用于指示出该MTC终端集合的接入控制信息的移动性管理网元适用范围(即指示接入网设备在为归属于MTC终端集合的MTC终端选择那些MME时，才启用该MTC终端集合的接入控制信息对该MTC终端进行接入控制)，例如可指示MTC终端集合的接入控制信息适用于下发该MTC终端集合的接入控制信息的移动性管理网元，或可指示出MTC终端集合的接入控制信息适用于由多个移动性管理网元组成的移动性管理网元集合(例如某个移动性管理网元池)，此时，接入网设备可关联存储该移动性管理网元(或移动性管理网元集合)的标识(例如地址、设备标识或其它标识)。MTC终端集合的接入控制信息的移动性管理网元适用范围指示信息，也可以指示出该MTC终端集合的接入控制信息适用于所有移动性管理网元，此时，接入网设备可不关联存储该移动性管理网元的标识。In an application scenario, the access network device may store the access control information of the MTC terminal set issued by the mobility management network element. Further, the mobility management network element may also issue the mobility management network element applicable scope indication information of the access control information of the MTC terminal set to the access network device, wherein the mobility management network element applicable scope indication information is used for Indicates the scope of application of the mobility management network element of the access control information of the MTC terminal set (that is, instructs the access network device to enable the access of the MTC terminal set when selecting those MMEs for the MTC terminals belonging to the MTC terminal set access control information for the MTC terminal), for example, it may indicate that the access control information of the MTC terminal set is applicable to the mobility management network element that issues the access control information of the MTC terminal set, or may indicate that the MTC terminal set The access control information is applicable to a mobility management network element set (for example, a certain mobility management network element pool) composed of multiple mobility management network elements. At this time, the access network device can associate and store the mobility management network element An identifier (such as an address, a device identifier or other identifiers) of an element (or a set of mobility management network elements). The mobility management network element application scope indication information of the access control information of the MTC terminal set may also indicate that the access control information of the MTC terminal set is applicable to all mobility management network elements. At this time, the access network device may not be associated The identifier of the mobility management network element is stored.

而接入网设备在为上述MTC终端选择的移动性管理网元落入移动性管理网元适用范围指示信息所指示的范围时，再启用该MTC终端所属MTC终端集合的接入控制信息，此时，接入网设备按照该MTC终端所属MTC终端集合的接入控制信息中的接入控制指示，对上述MTC终端进行接入控制。When the mobility management network element selected for the above-mentioned MTC terminal falls within the scope indicated by the indication information of the applicable range of the mobility management network element, the access network device enables the access control information of the MTC terminal set to which the MTC terminal belongs. , the access network device performs access control on the MTC terminal according to the access control indication in the access control information of the MTC terminal set to which the MTC terminal belongs.

在实际应用中，接入网设备根据上述消息携带的集合标识，在事先存储的MTC终端集合的接入控制信息中查找，根据查找结果确定与该集合标识对应的接入控制指示，按照确定出的该集合标识对应的接入控制指示对上述MTC终端进行接入控制。此外，若未查找到上述消息携带的集合标识对应的接入控制指示，则可按照现有方式进行对MTC设备进行接入控制。In practical applications, the access network device searches the access control information of the MTC terminal set stored in advance according to the aggregate identifier carried in the above message, and determines the access control instruction corresponding to the aggregate identifier according to the search result, and according to the determined The access control corresponding to the aggregate identifier indicates that access control is performed on the above-mentioned MTC terminal. In addition, if the access control indication corresponding to the aggregate identifier carried in the above message is not found, the access control of the MTC device may be performed in an existing manner.

当然，移动性管理网元可向接入网设备下发多个MTC终端集合的接入控制信息，接入网设备可以按照类似方式，根据各MTC终端集合的接入控制信息，对归属于相应MTC终端集合的MTC终端进行接入控制，而不同MTC终端集合的接入控制方式可能不同，也可能相同。Of course, the mobility management network element can deliver the access control information of multiple sets of MTC terminals to the access network device, and the access network device can use a similar method, according to the access control information of each set of MTC terminals, to The MTC terminals in the MTC terminal set perform access control, and the access control modes of different MTC terminal sets may be different or the same.

在一种应用场景下，MTC终端集合的接入控制信息中包含的接入控制指示可包括：允许接入指示、禁止接入指示、延迟接入指示(可指示延迟接入时长)、允许接入时长指示(可指示允许接入的时长)、允许接入时段指示或禁止接入时段指示等。In one application scenario, the access control indications contained in the access control information of the MTC terminal set may include: indication of access allowed, indication of prohibited access, indication of delayed access (can indicate the duration of delayed access), allowed access Indication of access time (can indicate the duration of access allowed), indication of allowed access time period or indication of prohibited access time period, etc.

接入网设备例如可按照MTC终端集合的接入控制信息中的允许接入指示，允许MTC终端接入(例如向MTC终端发送RRC建立接受消息)；或，按照MTC终端集合的接入控制信息中的禁止接入指示，禁止MTC终端接入(如向第一MTC终端发送RRC建立拒绝或释放消息)；或，按照MTC终端集合的接入控制信息中的延迟接入指示，指示MTC终端设定延迟时长后再进行接入；或，按照MTC终端集合的接入控制信息中的允许接入时长指示，控制MTC终端在的接入时长(如只允许某类应用的MTC终端进行设定时长的接入或业务，当该设定时长到达后则中断该MTC终端连接或业务)；或，按照MTC终端集合的接入控制信息中的允许接入时段指示，指示MTC终端在允许接入时段进行接入(例如只允许某类应用的MTC终端在特定时段接入)；或，按照MTC终端集合的接入控制信息中的禁止接入时段指示，指示MTC终端禁止在禁止接入时段进行接入。The access network device may, for example, allow the MTC terminal to access (for example, send an RRC establishment acceptance message to the MTC terminal) according to the access control indication in the access control information of the MTC terminal set; or, according to the access control information of the MTC terminal set The access prohibition instruction in the MTC terminal is prohibited from accessing (such as sending an RRC establishment rejection or release message to the first MTC terminal); or, according to the delayed access instruction in the access control information of the MTC terminal set, instruct the MTC terminal to set or, according to the allowed access duration indication in the access control information of the MTC terminal set, control the access duration of the MTC terminal (for example, only allow the MTC terminal of a certain type of application to set the duration access or service of the MTC terminal, when the set duration arrives, the connection or service of the MTC terminal will be interrupted); or, according to the indication of the allowable access period in the access control information of the MTC terminal set, instruct the MTC terminal to allow the access period Perform access (for example, only allow MTC terminals of a certain type of application to access during specific periods); or, according to the indication of prohibited access periods in the access control information of the MTC terminal set, instruct MTC terminals to prohibit access during prohibited access periods enter.

由上可见，本实施例中移动性管理网元向接入网设备下发MTC终端集合的接入控制信息，接入网设备在接收到归属于该MTC终端集合的MTC终端在无线资源控制连接建立过程中发送的消息时，根据该MTC终端集合的接入控制信息，对归属于该MTC终端进行接入控制，该机制可以实现对特定或所有的MTC终端进行例如接入时长、允许/禁止接入时段、禁止接入、延迟接入等接入控制，使得接入受限的MTC终端可在接入网就受到相应的控制，能有效降低核心网结点信令拥塞的发生几率，进而提升网络的抗风险性能。It can be seen from the above that in this embodiment, the mobility management network element sends the access control information of the MTC terminal set to the access network device, and the access network device receives the MTC terminal belonging to the MTC terminal set before establishing the radio resource control connection. When the message is sent during the process, according to the access control information of the MTC terminal set, access control is performed on the MTC terminal belonging to the MTC terminal. Access control such as entry period, access prohibition, and delayed access, so that MTC terminals with limited access can be controlled accordingly in the access network, which can effectively reduce the probability of core network node signaling congestion, thereby improving Anti-risk performance of the network.

实施例二、Embodiment two,

为便于更好的理解，下面以MME将某个MTC终端集合(以下简称MTC终端集合A)的接入控制信息下发给基站(eNB)；基站根据该MTC终端集合的接入控制信息，对归属于该MTC终端集合的MTC终端进行接入控制的一种具体实现过程为例，对本发明实施例接入控制的实现方法的另一个实施例进行说明。For a better understanding, the MME sends the access control information of a certain MTC terminal set (hereinafter referred to as MTC terminal set A) to the base station (eNB); Another embodiment of the implementation method of the access control in the embodiment of the present invention will be described by taking a specific implementation process of the access control performed by the MTC terminals belonging to the MTC terminal set as an example.

参见图3、具体可以包括：Referring to Figure 3, the details may include:

301、MME向基站下发MTC终端集合A的接入控制信息；301. The MME sends the access control information of the MTC terminal set A to the base station;

其中，MME可以在一种或多种条件的触发下，向基站下发MTC终端集合A的接入控制信息，例如可在自身或SGW/PGW发生负载过重时、在首次获知有归属于MTC终端集合A的某个MTC终端在进行接入或业务时、在其它设备的指示下、或在其它条件的触发下向基站下发MTC终端集合A的接入控制信息。Among them, the MME can send the access control information of the MTC terminal set A to the base station under the trigger of one or more conditions. A certain MTC terminal of terminal set A sends the access control information of MTC terminal set A to the base station when performing access or service, under the instruction of other devices, or triggered by other conditions.

在一种应用场景下，MME可以将MTC终端集合A的接入控制信息携带在例如接口建立消息、MME配置更新消息、负载过重指示消息、专门定义的MTC终端集合控制消息或其它的消息中，向基站下发该MTC终端集合A的接入控制信息。In an application scenario, the MME may carry the access control information of the MTC terminal set A in, for example, an interface establishment message, an MME configuration update message, an overload indication message, a specially defined MTC terminal set control message, or other messages , and deliver the access control information of the MTC terminal set A to the base station.

其中，MTC终端集合A的接入控制信息可包括：MTC终端集合A的集合标识，以及该集合标识对应的接入控制指示(一条或多条)。Wherein, the access control information of the MTC terminal set A may include: the set identifier of the MTC terminal set A, and the access control indication (one or more) corresponding to the set identifier.

在实际应用中，例如MTC终端集合A包括某类特定业务的MTC终端，MME例如可在确定其自身负载过重(如超过某设定阈值)时，生成或从其它设备(例如可从PGW、网管系统、运营商数据库或其它实体)获取MTC终端集合A的接入控制信息，而此时MTC终端集合A的接入控制信息中的接入控制指示例如可包括：禁止接入指示或延迟接入指示(例如指示MTC终端可在延迟一个固定时长或随机时长后再次发起相应接入)等，以指示接入网设备禁止或延迟归属于MTC终端集合A的MTC终端的接入，起到负载过重的MME进行减负载的目的；当MME确定负载减轻(如低于某设定阈值)后，MME可重新生成或从其它设备获取更新的MTC终端集合A的接入控制信息，而此时MTC终端集合A的接入控制信息的接入控制指示例如可包括允许接入指示等，以指示接入网设备允许归属于MTC终端集合A的MTC终端的接入，进而恢复常态。In practical applications, for example, the MTC terminal set A includes MTC terminals of a certain type of specific service. For example, when the MME determines that its own load is too heavy (for example, exceeding a certain set threshold), it can generate or receive from other devices (for example, from the PGW, network management system, operator database or other entities) to obtain the access control information of the MTC terminal set A, and at this time, the access control indication in the access control information of the MTC terminal set A may include, for example: access prohibition indication or delayed access Instructions (such as indicating that MTC terminals can initiate corresponding access again after a fixed or random time delay) etc., to instruct access network equipment to prohibit or delay the access of MTC terminals belonging to MTC terminal set A, and serve as a load The purpose of reducing the load of the overweight MME; when the MME determines that the load is reduced (such as lower than a certain threshold), the MME can regenerate or obtain the updated access control information of the MTC terminal set A from other devices, and at this time The access control indication of the access control information of the MTC terminal set A may include, for example, an access permission indication, etc., to instruct the access network device to allow the access of the MTC terminals belonging to the MTC terminal set A, so as to restore the normal state.

或者，例如MTC终端集合A包括某类非即时性业务的MTC终端，MME例如也可在首次获知有归属于MTC终端集合A的某个MTC终端接入或进行业务时，或在网管系统或其它设备的指示下，或在MME上电后或其它时刻，生成或从其它设备(例如可从PGW、网管系统、运营商数据库或其它实体)获取MTC终端集合A的接入控制信息，而此时MTC终端集合A的接入控制信息的接入控制指示例如可包括：允许接入时长指示(例如允许接入10秒)、允许接入时段指示或禁止接入时段指示等，以指示接入网设备允许归属于MTC终端集合A的MTC终端在网络通常空闲的时段(例如0点到16点)接入，或者，禁止归属于MTC终端集合A的MTC终端的在通常繁忙的时段接入(例如16点到0点)，或者，控制归属于MTC终端集合A的MTC终端的接入时长，以起到平滑网络承载的作用。Or, for example, if the MTC terminal set A includes MTC terminals of a certain type of non-immediate service, the MME may, for example, learn for the first time that a certain MTC terminal belonging to the MTC terminal set A accesses or performs services, or in the network management system or other Under the instruction of the device, or after the MME is powered on or at other times, the access control information of the MTC terminal set A is generated or obtained from other devices (for example, from the PGW, network management system, operator database or other entities), and at this time The access control indication of the access control information of the MTC terminal set A may include, for example: an indication of the allowed access duration (for example, 10 seconds allowed), an indication of an allowed access period or an indication of a prohibited access period, etc., to indicate that the access network The device allows MTC terminals belonging to MTC terminal set A to access during periods when the network is usually idle (such as 0:00 to 16:00), or prohibits MTC terminals belonging to MTC terminal set A from accessing during usually busy periods (such as 16:00 to 0:00), or control the access duration of the MTC terminals belonging to the MTC terminal set A, so as to smooth the network bearer.

302、基站可保存MTC终端集合A的接入控制信息；302. The base station can save the access control information of the MTC terminal set A;

其中，基站可保存从MME获取到的MTC终端集合A的接入控制信息，还可以进一步保存该MME的标识信息(例如地址)。Wherein, the base station may store the access control information of the MTC terminal set A obtained from the MME, and may further store the identification information (such as an address) of the MME.

在一种应用场景下，基站可保存MTC终端集合A的接入控制信息以及MME的标识(例如，该MTC终端集合A的接入控制信息是MME在MME负载过重时下发的)，当接收到归属于MTC终端集合A的MTC终端在RRC连接建立过程中发送的消息(例如RRC请求消息)时，若基站为该MTC终端选择的是该MME，则启用从该MME获取到的MTC终端集合A的接入控制信息，对该MTC终端进行接入控制；若发现该MTC终端选择的是其它MME而并非该MME，则可禁用从该MME获取到的MTC终端集合A的接入控制信息对该MTC终端进行接入控制，例如可按照现有接入控制方式(或该MTC终端选择的MME所下发的MTC终端集合A的接入控制信息)对该MTC终端进行接入控制。又例如，基站可选择保存MTC终端集合A的接入控制信息而可不保存该MME的标识(例如该MTC终端集合A的接入控制信息是MME在PGW/SGW负载过重时、上电后或其它时刻，生成或从网管系统或PGW/SGW获得后下发的)，当接收到归属于MTC终端集合A的MTC终端在RRC连接建立过程中发送的消息时，无论基站为该MTC终端选择的那个MME，基站均按照获取到的MTC终端集合A的接入控制信息对该MTC终端进行接入控制。In one application scenario, the base station can save the access control information of MTC terminal set A and the identity of the MME (for example, the access control information of the MTC terminal set A is delivered by the MME when the MME load is too heavy), and when receiving When the MTC terminal belonging to the MTC terminal set A sends a message (such as an RRC request message) during the RRC connection establishment process, if the base station selects the MME for the MTC terminal, then activate the MTC terminal set obtained from the MME The access control information of A is used to control the access of the MTC terminal; if it is found that the MTC terminal chooses other MME instead of the MME, the access control information of the MTC terminal set A obtained from the MME can be disabled. The MTC terminal performs access control, for example, according to the existing access control mode (or the access control information of the MTC terminal set A delivered by the MME selected by the MTC terminal). For another example, the base station may choose to save the access control information of the MTC terminal set A without saving the identity of the MME (for example, the access control information of the MTC terminal set A is the MME when the PGW/SGW is overloaded, after power-on or At other times, it is generated or issued after being obtained from the network management system or PGW/SGW), when receiving the message sent by the MTC terminal belonging to the MTC terminal set A during the RRC connection establishment process, no matter the MTC terminal selected by the base station The MME and the base station perform access control on the MTC terminal set A according to the obtained access control information of the MTC terminal set A.

或者，MME还可以向基站下发MTC终端集合A的接入控制信息的MME适用范围指示信息，该MME适用范围指示信息用于指示出MTC终端集合A的接入控制信息的MME适用范围(即指示基站在为归属于MTC终端集合A的MTC终端选择那些MME时，才启用MTC终端集合A的接入控制信息对该MTC终端进行接入控制)，例如可以指示MTC终端集合A的接入控制信息适用于下发MTC终端集合A的接入控制信息的MME，或可指示出MTC终端集合A的接入控制信息适用于由多个MME组成的MME集合(例如某个MME池)，此时，基站可关联存储该MME(或MME集合)的标识(例如地址、设备标识或其它标识)。MTC终端集合A的接入控制信息的MME适用范围指示信息，也可以指示出MTC终端集合A的接入控制信息适用于所有MME，此时，接入网设备可不关联存储该MME的标识。而当基站为MTC终端a1选择的MME落入上述MME适用范围指示信息所指示的范围时，再启用MTC终端集合A的接入控制信息对第一MTC终端进行接入控制，若基站在为MTC终端a1选择的MME未落入上述MME适用范围指示信息所指示的范围，可禁用上述MTC终端集合A的接入控制信息，而采用其它方式对第一MTC终端进行接入控制。Alternatively, the MME may also send the MME applicable scope indication information of the access control information of the MTC terminal set A to the base station, and the MME applicable scope indication information is used to indicate the MME applicable scope of the access control information of the MTC terminal set A (that is, Instruct the base station to enable the access control information of the MTC terminal set A to perform access control on the MTC terminal when selecting those MMEs for the MTC terminals belonging to the MTC terminal set A), for example, it can indicate the access control of the MTC terminal set A The information is applicable to the MME that issues the access control information of the MTC terminal set A, or may indicate that the access control information of the MTC terminal set A is applicable to an MME set (such as a certain MME pool) composed of multiple MMEs. The base station may associate and store the identifier (such as address, device identifier or other identifiers) of the MME (or set of MMEs). The MME applicable range indication information of the access control information of the MTC terminal set A may also indicate that the access control information of the MTC terminal set A is applicable to all MMEs, and at this time, the access network device may not associate and store the identity of the MME. And when the MME selected by the base station for the MTC terminal a1 falls within the range indicated by the above-mentioned MME application scope indication information, the access control information of the MTC terminal set A is used to perform access control on the first MTC terminal. The MME selected by the terminal a1 does not fall within the range indicated by the MME applicable range indication information, and the access control information of the above MTC terminal set A may be disabled, and other methods are used to perform access control on the first MTC terminal.

例如，MME下发的MTC终端集合A的接入控制信息的MME适用范围指示所指示的范围为当前MME，此时，当接收到归属于MTC终端集合A的MTC终端在RRC连接建立过程中发送的消息时，若基站为该MTC终端选择的MME为当前MME(即落入到MME适用范围指示信息所指示的范围)，则启用MTC终端集合A的控制信息对该MTC终端进行接入控制，若基站为该MTC终端选择的是其它MME(即未落入到MME适用范围指示信息所指示的范围)，则禁用该MTC终端集合A的控制信息对该MTC终端进行接入控制，以此类推。For example, the scope indicated by the MME applicable scope indication of the access control information of the MTC terminal set A issued by the MME is the current MME. At this time, when the MTC terminal belonging to the MTC terminal set A sends the message, if the MME selected by the base station for the MTC terminal is the current MME (i.e. falls within the range indicated by the MME applicable range indication information), then enable the control information of the MTC terminal set A to perform access control on the MTC terminal, If the base station selects another MME for the MTC terminal (that is, it does not fall within the range indicated by the MME applicable range indication information), then disable the control information of the MTC terminal set A to perform access control on the MTC terminal, and so on .

又例如，MME下发的MTC终端集合A的接入控制信息的MME适用范围指示所指示的范围为所有MME，此时，当接收到归属于MTC终端集合A的MTC终端在RRC连接建立过程中发送的消息时，无论基站为该MTC终端选择的MME是哪个MME(都会落入到MME适用范围指示信息所指示的范围)，都启用MTC终端集合A的控制信息对该MTC终端进行接入控制，以此类推。For another example, the MME application scope indication of the access control information of the MTC terminal set A sent by the MME indicates that the range indicated is all MMEs. At this time, when the MTC terminal belonging to the MTC terminal set A is receiving When sending a message, regardless of the MME selected by the base station for the MTC terminal (it will fall into the range indicated by the MME applicable scope indication information), the control information of the MTC terminal set A is used to control the access of the MTC terminal , and so on.

303、基站接收MTC终端a1在RRC连接建立过程中发送的消息m1；303. The base station receives the message m1 sent by the MTC terminal a1 during the establishment of the RRC connection;

其中，消息m1例如是RRC连接请求消息或RRC连接完成消息，消息m1携带MTC终端所属的MTC终端集合的集合标识。Wherein, the message m1 is, for example, an RRC connection request message or an RRC connection complete message, and the message m1 carries the set identifier of the MTC terminal set to which the MTC terminal belongs.

304、基站若确定出MTC终端a1归属于MTC终端集合A，按照MTC终端集合A的接入控制信息中的接入控制指示，对MTC终端a1进行接入控制。304. If the base station determines that the MTC terminal a1 belongs to the MTC terminal set A, perform access control on the MTC terminal a1 according to the access control indication in the access control information of the MTC terminal set A.

在一种应用场景下，基站可以将消息m1携带的MTC终端a1归属于MTC终端集合的集合标识和MTC终端集合A的集合标识进行比较匹配，若相同，表明集合标识匹配成功，则确定MTC终端a1归属于MTC终端集合A；若不同，表明集合标识匹配成功，则确定MTC终端a1不归属于MTC终端集合A，此时可采用现有的接入控制方式其它接入控制方式对MTC终端a1进行接入控制，此处不做限定。下面对MTC终端a1归属于MTC终端集合A的情况进行说明：In one application scenario, the base station can compare and match the set ID of the MTC terminal a1 carried in the message m1 belonging to the MTC terminal set and the set ID of the MTC terminal set A, and if they are the same, it indicates that the set ID matches successfully, and then determines the MTC terminal a1 belongs to the MTC terminal set A; if it is different, it indicates that the set ID matches successfully, then it is determined that the MTC terminal a1 does not belong to the MTC terminal set A, and at this time, the existing access control method and other access control methods can be used to control the MTC terminal a1 Perform access control, which is not limited here. The following describes the situation that the MTC terminal a1 belongs to the MTC terminal set A:

在一种应用场景下，例如若MTC终端集合A的接入控制信息中的接入控制指示包括允许接入指示，则基站可按照MTC终端集合A的接入控制信息中的允许接入指示，允许MTC终端a1接入，例如向MTC终端a1发送消息m2，此时若消息m1为是RRC连接请求消息，则消息m2为RRC连接接受消息。In an application scenario, for example, if the access control indication in the access control information of the MTC terminal set A includes an access-allowed indication, the base station may follow the access-allowed indication in the access control information of the MTC terminal set A, To allow the MTC terminal a1 to access, for example, send a message m2 to the MTC terminal a1, at this time, if the message m1 is an RRC connection request message, then the message m2 is an RRC connection acceptance message.

又例如，若MTC终端集合A的接入控制信息中的接入控制指示包括：禁止接入指示，则基站按照MTC终端集合A的接入控制信息中的禁止接入指示，禁止MTC终端a1接入，例如向MTC终端a1发送消息m2，消息m2中可携带禁止接入指示，此时，若消息m1为是RRC连接请求消息，则消息m2为RRC连接拒绝消息；若消息m1为是RRC连接完成消息，则消息m2为RRC连接释放消息。For another example, if the access control indication in the access control information of the MTC terminal set A includes: access prohibition indication, then the base station prohibits the MTC terminal a1 from accessing according to the access prohibition indication in the access control information of the MTC terminal set A. For example, send a message m2 to the MTC terminal a1, and the message m2 may carry an access prohibition indication. At this time, if the message m1 is an RRC connection request message, then the message m2 is an RRC connection rejection message; if the message m1 is an RRC connection If the message is completed, the message m2 is an RRC connection release message.

又例如，若MTC终端集合A的接入控制信息中的接入控制指示包括：延迟接入指示，则基站按照MTC终端集合A的接入控制信息中的延迟接入指示，指示MTC终端a1设定延迟时长后再进行接入，可向MTC终端a1发送消息m2，此时，若消息m1为是RRC连接请求消息，则消息m2可为RRC连接拒绝消息；若消息m1为是RRC连接完成消息，则消息m2可为RRC连接释放消息。其中，消息m2中可携带固定或随机的延迟接入时长(例如25秒)，MTC终端a1则可在等待该延迟接入时长后，再次发起接入；或者，消息m2中也可不携带设定的延迟接入的时间，MTC终端a1可在等待默认的延迟接入时长(例如40秒)后，再次发起接入。For another example, if the access control indication in the access control information of the MTC terminal set A includes: a delayed access indication, the base station instructs the MTC terminal a1 to set To access after a certain delay, a message m2 can be sent to the MTC terminal a1. At this time, if the message m1 is an RRC connection request message, the message m2 can be an RRC connection rejection message; if the message m1 is an RRC connection completion message , then the message m2 may be an RRC connection release message. Among them, the message m2 may carry a fixed or random delayed access duration (for example, 25 seconds), and the MTC terminal a1 may initiate the access again after waiting for the delayed access duration; or, the message m2 may not carry the set The MTC terminal a1 can initiate access again after waiting for the default delayed access time (for example, 40 seconds).

又例如，若MTC终端集合A的接入控制信息中的接入控制指示包括：允许接入时长指示，则基站按照MTC终端集合A的接入控制信息中的允许接入时长指示，控制MTC终端a1的接入时长，此时可先向MTC终端a1发送消息m2，其中可以携带允许接入时长信息。若消息m1为是RRC连接请求消息，则消息m2可为RRC连接接受消息。当允许接入时长到达时，可由MTC终端a1发起中断业务或连接，或者由基站发起中断MTC终端a1的连接或业务。For another example, if the access control indication in the access control information of the MTC terminal set A includes: an indication of the allowed access duration, the base station controls the MTC terminal according to the allowed access duration indication in the access control information of the MTC terminal set A. The access duration of a1, at this time, a message m2 may be sent to the MTC terminal a1, which may carry information about the allowed access duration. If the message m1 is an RRC connection request message, then the message m2 may be an RRC connection acceptance message. When the allowed access duration is reached, the MTC terminal a1 may initiate interruption of the service or connection, or the base station may initiate the interruption of the connection or service of the MTC terminal a1.

又例如，若MTC终端集合A的接入控制信息中的接入控制指示包括：允许接入时段指示，则基站按照MTC终端集合A的接入控制信息中的允许接入时段指示，指示MTC终端a1在允许接入时段进行接入，可向MTC终端a1发送消息m2，其中，若当前时间落入到允许接入时段之内(例如当前时间为11点，允许接入时段为0点到16点)，则基站可允许MTC终端a1接入，此时，若消息m1为是RRC连接请求消息，则消息m2可为RRC连接接受消息；若当前时间未落入到允许接入时段之内(如当前时间为17点，允许接入时段为0点到12点)，则基站拒绝MTC终端a1接入，消息m2中可携带允许接入时段信息，此时，若消息m1为是RRC连接请求消息，则消息m2可为RRC连接拒绝消息；若消息m1为是RRC连接完成消息，则消息m2可为RRC连接释放消息。For another example, if the access control indication in the access control information of the MTC terminal set A includes: an indication of an allowed access period, the base station instructs the MTC terminal according to the allowed access period indication in the access control information of the MTC terminal set A a1 accesses during the allowed access period, and can send a message m2 to the MTC terminal a1, wherein, if the current time falls within the allowed access period (for example, the current time is 11:00, the allowed access period is 0:00 to 16:00 point), the base station can allow the MTC terminal a1 to access, at this time, if the message m1 is an RRC connection request message, then the message m2 can be an RRC connection acceptance message; if the current time does not fall within the allowed access period ( For example, the current time is 17:00, and the allowed access period is from 0:00 to 12:00), then the base station rejects the access of the MTC terminal a1, and the message m2 can carry the allowed access period information. At this time, if the message m1 is an RRC connection request message, the message m2 may be an RRC connection rejection message; if the message m1 is an RRC connection completion message, then the message m2 may be an RRC connection release message.

又例如，若MTC终端集合A的接入控制信息中的接入控制指示包括：禁止接入时段指示，则基站按照MTC终端集合A的接入控制信息中的禁止接入时段指示，指示MTC终端a1禁止在禁止接入时段进行接入，可以向MTC终端a1发送消息m2，其中，若当前时间落入到禁止接入时段之内(例如当前时间为19点，禁止接入时段为16点到24点)，则基站拒绝MTC终端a1接入，消息m2中可携带禁止接入时段信息，此时，若消息m1为是RRC连接请求消息，则消息m2可为RRC连接拒绝消息；若消息m1为是RRC连接完成消息，则消息m2可为RRC连接释放消息。若当前时间未落入到禁止接入时段之内(例如当前时间为10点，禁止接入时段为16点到24点)，则基站允许MTC终端a1接入，此时若消息m1为是RRC连接请求消息，则消息m2可为RRC连接接收消息。For another example, if the access control indication in the access control information of the MTC terminal set A includes: an indication of a prohibited access period, the base station instructs the MTC terminal according to the prohibited access period indication in the access control information of the MTC terminal set A a1 prohibits access during the access prohibition period, and can send a message m2 to the MTC terminal a1, wherein, if the current time falls within the access prohibition period (for example, the current time is 19 o'clock, and the access prohibition period is from 16 o'clock to 24), the base station rejects the access of the MTC terminal a1, and the message m2 may carry information about the prohibited access period. At this time, if the message m1 is an RRC connection request message, the message m2 may be an RRC connection rejection message; if the message m1 Since it is an RRC connection completion message, the message m2 may be an RRC connection release message. If the current time does not fall within the prohibited access period (for example, the current time is 10:00, and the prohibited access period is from 16:00 to 24:00), the base station allows the MTC terminal a1 to access. If the message m1 is RRC connection request message, the message m2 may be an RRC connection reception message.

进一步的，若基站A获取到了多个MTC终端集合(其中包括MTC终端集合A)的接入控制信息，则基站A可以按照保存MTC终端集合A的接入控制信息的方式，保存其它一个或多个MTC终端集合的接入控制信息。当接收到某个MTC终端在RRC连接建立过程中发送的消息时，基站可以在先查找(例如通过集合标识进行查找)是否已保存了该MTC终端所归属MTC终端集合的接入控制信息，若能够查找到(说明已保存)，则按照对应的接入控制信息对该MTC终端进行接入控制；若不能查找到(说明未保存)，则按照现有或其它方式对该MTC终端进行接入控制。Further, if base station A obtains the access control information of multiple MTC terminal sets (including MTC terminal set A), then base station A may store the access control information of MTC terminal set A in the manner of storing other one or more Access control information for a set of MTC terminals. When receiving a message sent by an MTC terminal during the establishment of an RRC connection, the base station may first search (for example, search through the set identifier) whether the access control information of the MTC terminal set to which the MTC terminal belongs has been saved, if If it can be found (indicating that it has been saved), then perform access control on the MTC terminal according to the corresponding access control information; control.

可以理解，在具体实现时可能采用多种适宜的接入控制方式，而不限于上述举例的接入控制方式。It can be understood that various suitable access control methods may be adopted during specific implementation, and are not limited to the above-mentioned example access control methods.

进一步的，如果接入控制结果为允许MTC终端a1接入，基站还可将从MTC终端a1获得的集合标识通知给MME。MME或其它核心网实体可以根据该集合标识，对MTC终端a1进行进一步的控制或计费等；MME或其它核心网实体也可以根据该集合标识在负载过重时生成MTC终端集合A的接入控制信息。Further, if the access control result is that the MTC terminal a1 is allowed to access, the base station may also notify the MME of the set identifier obtained from the MTC terminal a1. The MME or other core network entities can further control or charge the MTC terminal a1 according to the set identifier; the MME or other core network entities can also generate access to the MTC terminal set A when the load is too heavy according to the set identifier control information.

在一种应用场景下，若此前是MME由于某个核心网节点负载过重而向基站下发该核心网节点关于MTC终端集合A的控制信息，当发现该核心网节点负载发生变化时，MME可更新基站中的MTC终端集合A的控制信息(例如可将禁止接入指示修改为，允许接入时长指示或允许接入指示)。当然，在其它一些情况下(例如网络环境发生了变化、MTC终端集合A的业务类型或签约数据发生了变化)，MME也可更新基站中的MTC终端集合A的控制信息(例如可修改允许/禁止接入时段，允许接入时长等接入控制参数)。MME可利用接口建立消息、或者MME配置更新消息、或者负载过重指示取消消息、专门定义的MTC终端集合控制消息或其它的消息，更新基站中的MTC终端集合A的接入控制信息。基站则更新此前保存的MTC终端集合A的接入控制信息，此后便利用更新的MTC终端集合A的接入控制信息(即基站始终利用最新的MTC终端集合A的接入控制信息)，对归属于MTC终端集合A的MTC终端进行接入控制。In an application scenario, if the MME previously sent the control information of a core network node to the base station due to the heavy load of the core network node on the MTC terminal set A, when it is found that the load of the core network node changes, the MME The control information of the MTC terminal set A in the base station may be updated (for example, the indication of prohibiting access may be changed to an indication of the duration of access allowed or an indication of allowed access). Of course, in some other situations (for example, the network environment changes, the service type or subscription data of the MTC terminal set A changes), the MME can also update the control information of the MTC terminal set A in the base station (for example, the permission/ Access control parameters such as prohibited access period, allowed access duration, etc.). The MME can update the access control information of the MTC terminal set A in the base station by using an interface establishment message, or an MME configuration update message, or an overload indication cancel message, a specially defined MTC terminal set control message or other messages. The base station updates the previously saved access control information of the MTC terminal set A, and then uses the updated access control information of the MTC terminal set A (that is, the base station always uses the latest access control information of the MTC terminal set A) to determine the belonging Access control is performed on the MTC terminals of the MTC terminal set A.

可以理解，上述是以对归属MTC终端集合A的MTC终端进行接入控制进行举例说明的，当然，移动性管理网元可向接入网设备下发多个MTC终端集合的接入控制信息，接入网设备按照类似方式，根据各MTC终端集合的接入控制信息，对归属于相应MTC终端集合的MTC终端进行接入控制，而不同MTC终端集合的接入控制方式可能不同，也可能相同。It can be understood that the above is an example of the access control of the MTC terminals belonging to the MTC terminal set A. Of course, the mobility management network element can deliver the access control information of multiple MTC terminal sets to the access network device. In a similar manner, the access network device performs access control on the MTC terminals belonging to the corresponding MTC terminal set according to the access control information of each MTC terminal set, and the access control methods of different MTC terminal sets may be different or the same .

由上技术方案可见，本实施例MME向基站下发MTC终端集合的接入控制信息，基站在接收到归属于该MTC终端集合的MTC终端在无线资源控制连接建立过程中发送的消息时，根据该MTC终端集合的接入控制信息，对归属于该MTC终端进行接入控制，该机制可以实现对特定或所有的MTC终端进行例如接入时长、允许/禁止接入时段、禁止接入、延迟接入等接入控制，使得接入受限的MTC终端在接入网就受到相应的控制，可快速降低负载过重或平滑网络承载，能有效降低核心网结点信令负载过重的发生几率，进而提升网络的抗风险性能。It can be seen from the above technical solution that the MME in this embodiment sends the access control information of the MTC terminal set to the base station. When the base station receives the message sent by the MTC terminal belonging to the MTC terminal set during the establishment of the radio resource control connection, The access control information of the MTC terminal set controls access to the MTC terminal belonging to the MTC terminal. This mechanism can implement specific or all MTC terminals such as access duration, allowed/prohibited access period, prohibited access, delay Access control, such as access, enables MTC terminals with limited access to be subject to corresponding control in the access network, which can quickly reduce overload or smooth network load, and can effectively reduce the occurrence of overload of core network node signaling probability, thereby improving the anti-risk performance of the network.

进一步的，利用介绍的多种接入控制方式，可以灵活的满足多种场景的负载过重控制需求。Furthermore, using the multiple access control methods introduced can flexibly meet the load overload control requirements of various scenarios.

实施例三Embodiment three

本实施例中主要从移动性管理网元的角度，描述本发明实施例的一种机器类型通讯终端的接入控制方法。本发明实施例机器类型通讯终端的接入控制方法的另一个实施例可以包括：移动性管理网元获得机器类型通讯MTC终端集合的接入控制信息；按照上述MTC终端集合的接入控制信息，对归属于上述MTC终端集合的MTC终端进行接入控制；或，向接入网设备下发上述MTC终端集合的接入控制信息，上述MTC终端集合的接入控制信息用于指示上述接入网设备按照上述MTC终端集合的接入控制信息，对归属于上述MTC终端集合的MTC终端进行接入控制。In this embodiment, a method for controlling access of a machine type communication terminal according to an embodiment of the present invention is mainly described from the perspective of a mobility management network element. Another embodiment of the access control method for a machine type communication terminal in the embodiment of the present invention may include: the mobility management network element obtains access control information of a machine type communication MTC terminal set; according to the above access control information of the MTC terminal set, Perform access control on the MTC terminals belonging to the above-mentioned MTC terminal set; or, issue the access control information of the above-mentioned MTC terminal set to the access network device, and the access control information of the above-mentioned MTC terminal set is used to indicate that the above-mentioned access network The device performs access control on the MTC terminals belonging to the above-mentioned MTC terminal set according to the access control information of the above-mentioned MTC terminal set.

参见图4，具体步骤可以包括：Referring to Figure 4, specific steps may include:

410、移动性管理网元获得MTC终端集合的接入控制信息；410. The mobility management network element obtains the access control information of the MTC terminal set;

其中，该MTC终端集合的接入控制信息可包含该MTC终端集合的集合标识和对应的接入控制指示。Wherein, the access control information of the MTC terminal set may include a set identifier of the MTC terminal set and a corresponding access control indication.

在一种应用场景下，移动性管理网元(以MME为例)可在发现自身的负载过重程度超过某一设定阈值时，或是在发现PGW/SGW的负载过重程度过高时(例如接收到PGW负载过重指示，或从第三方设备获知PGW负载过重)，生成或从网管系统或其它设备获取MTC终端集合的接入控制信息。In one application scenario, the mobility management network element (take MME as an example) can find that its own overload exceeds a certain threshold, or when it finds that the PGW/SGW is too heavily loaded (For example, receiving an indication that the PGW is overloaded, or learning that the PGW is overloaded from a third-party device), generating or obtaining access control information of the MTC terminal set from the network management system or other devices.

或者，MME例如也可在首次获知有归属于某个MTC终端集合的某个MTC终端在接入或进行业务时，或在网管系统或其它网元的指示下，或在上电后或其它时刻，生成或从其它设备(例如可从PGW、网管系统、运营商数据库或其它实体)获取该MTC终端集合的接入控制信息。Or, for example, when the MME learns for the first time that a certain MTC terminal belonging to a certain MTC terminal set is accessing or performing services, or under the instructions of the network management system or other network elements, or after power-on or at other times , generate or acquire the access control information of the MTC terminal set from other devices (for example, PGW, network management system, operator database or other entities).

其中，MTC终端集合可以是根据业务类型、访问的目的地址、使用的APN、设备类型或其它特征属性划分成的；而MTC终端集合的集合标识可为：业务类型标识、APN、访问的目的地址、设备类型、分配的特定集合标识或其它的标识。Among them, the MTC terminal set can be divided according to the service type, the destination address of the visit, the APN used, the device type or other characteristic attributes; and the set identifier of the MTC terminal set can be: service type identifier, APN, visit destination address , device type, assigned specific collection ID, or other ID.

可以理解，本实施例中的MTC终端集合可包括一个或多个MTC终端，甚至所有的MTC终端(例如将所有MTC终端划分为一个MTC终端集合)。It can be understood that the MTC terminal set in this embodiment may include one or more MTC terminals, or even all MTC terminals (for example, all MTC terminals are divided into one MTC terminal set).

在一种应用场景下，PGW可在因第一MTC终端集合(例如此处第一MTC终端集合是根据访问的目的地址、使用的APN或其它特征属性划分成的)、其它MTC终端集合、或普通用户终端的接入或业务，导致其负载过重程度过高时，通过例如SGW、网管系统或其它第三方设备，向MME下发负载过重指示消息，其中可携带第一MTC终端集合的接入控制信息(或携带第一MTC终端集合的集合标识和相关接入控制参数(如延迟接入时长)，MME据此生成第一MTC终端集合的接入控制信息)，也就获得了第一MTC终端集合的接入控制信息(例如指示第一MTC终端集合的MTC终端延迟接入或禁止接入等)。In an application scenario, the PGW may be based on the first MTC terminal set (for example, here the first MTC terminal set is divided according to the destination address of the visit, the APN used or other characteristic attributes), other MTC terminal sets, or When the access or business of a common user terminal causes its overload to be too high, send an overload indication message to the MME through, for example, the SGW, network management system or other third-party equipment, which may carry the information of the first MTC terminal set access control information (or carry the set identifier of the first MTC terminal set and related access control parameters (such as delay access duration), and the MME generates the access control information of the first MTC terminal set based on this), and also obtains the first MTC terminal set Access control information of a set of MTC terminals (for example, indicating that the MTC terminals of the first set of MTC terminals delay access or prohibit access, etc.).

举例来说，移动性管理网元可接收分组数据网络网关PGW通过服务网关SGW下发的归属第一MTC终端集合的MTC终端的控制面消息，从该控制面消息中获取第一MTC终端集合的接入控制信息(此处，PGW下发的控制面消息中携带的第一MTC终端集合的接入控制信息可以不包含第一MTC终端集合的集合标识，而移动性管理网元可根据该控制面消息确定出该接入控制信息对应于第一MTC终端集合)。或，PGW可在负载过重或减轻时，将PGW的负载状况和第一MTC终端集合的接入控制信息下发到第三方设备，移动性管理网元可在需要为MTC终端选择PGW时，向记录有PGW的负载状况和第一MTC终端集合的接入控制信息的第三方设备查询，获取第一MTC终端集合的接入控制信息。或，移动性管理网元可接收来自第三方设备的设备级管理消息，从该设备级管理消息中获取第一MTC终端集合的接入控制信息，其中，第一MTC终端集合的接入控制信息由PGW通过与第三方设备之间的设备级管理消息下发的到第三方设备。For example, the mobility management network element may receive the control plane message of the MTC terminals belonging to the first MTC terminal set sent by the packet data network gateway PGW through the serving gateway SGW, and obtain the information of the first MTC terminal set from the control plane message. Access control information (here, the access control information of the first MTC terminal set carried in the control plane message issued by the PGW may not include the set identifier of the first MTC terminal set, and the mobility management network element may It is determined in the face message that the access control information corresponds to the first set of MTC terminals). Or, when the load is too heavy or lightened, the PGW can send the load status of the PGW and the access control information of the first set of MTC terminals to the third-party device, and the mobility management network element can select the PGW for the MTC terminal when it needs to, Query the third-party device that records the load status of the PGW and the access control information of the first MTC terminal set to obtain the access control information of the first MTC terminal set. Or, the mobility management network element may receive a device-level management message from a third-party device, and obtain the access control information of the first MTC terminal set from the device-level management message, where the access control information of the first MTC terminal set Delivered to third-party devices by the PGW through device-level management messages between the PGW and the third-party device.

420、移动性管理网元按照上述MTC终端集合的接入控制信息，对归属于上述MTC终端集合的MTC终端进行接入控制；或，向接入网设备下发上述MTC终端集合的接入控制信息，上述MTC终端集合的接入控制信息用于指示上述接入网设备按照上述MTC终端集合的接入控制信息，对归属于上述MTC终端集合的MTC终端进行接入控制。420. The mobility management network element performs access control on the MTC terminals belonging to the above-mentioned MTC terminal set according to the access control information of the above-mentioned MTC terminal set; or, sends the access control of the above-mentioned MTC terminal set to the access network device The access control information of the MTC terminal set is used to instruct the access network device to perform access control on the MTC terminals belonging to the MTC terminal set according to the access control information of the MTC terminal set.

下面主要以移动性管理网元向接入网设备下发MTC终端集合的接入控制信息，以指示接入网设备按照该MTC终端集合的接入控制信息，对归属于该MTC终端集合的MTC终端进行接入控制为例进行说明。The following mainly uses the mobility management network element to deliver the access control information of the MTC terminal set to the access network device, so as to instruct the access network device to perform MTCs belonging to the MTC terminal set according to the access control information of the MTC terminal set. The terminal performs access control as an example for description.

其中，移动性管理网元在一种或多种条件的触发下，通过多种方式，向接入网设备下发MTC终端集合的接入控制信息。Wherein, the mobility management network element sends the access control information of the MTC terminal set to the access network device in various ways under the trigger of one or more conditions.

在一种应用场景下，移动性管理网元可以将MTC终端集合的接入控制信息携带在接口建立消息、配置更新消息、负载过重指示消息、专门定义的MTC终端集合控制消息或其它的消息中，以向接入网设备下发该MTC终端集合的接入控制信息。In an application scenario, the mobility management network element can carry the access control information of the MTC terminal set in the interface establishment message, configuration update message, overload indication message, specially defined MTC terminal set control message or other messages , so as to deliver the access control information of the MTC terminal set to the access network device.

接入网设备可将移动性管理网元下发的MTC终端集合的接入控制信息进行存储，并可以进一步关联存储该移动性管理网元的标识(例如移动性管理网元的地址、设备标识或其它标识)。The access network device can store the access control information of the MTC terminal set issued by the mobility management network element, and can further associate and store the identity of the mobility management network element (such as the address of the mobility management network element, the device identification or other identifiers).

进一步的，移动性管理网元还可以向接入网设备下发MTC终端集合的接入控制信息的移动性管理网元适用范围指示信息(可以和该MTC终端集合的接入控制信息同时下发给接入网设备)，该移动性管理网元适用范围指示信息用于指示接入网设备在为归属于该MTC终端集合的MTC终端选择的移动性管理网元落入该移动性管理网元适用范围指示信息所指示的范围时，按照该MTC终端集合的接入控制信息中的接入控制指示，对相应MTC终端进行接入控制。Further, the mobility management network element can also deliver the mobility management network element applicable scope indication information of the access control information of the MTC terminal set to the access network device (it can be issued simultaneously with the access control information of the MTC terminal set For access network equipment), the indication information of the scope of application of the mobility management network element is used to indicate that the mobility management network element selected by the access network equipment for the MTC terminal belonging to the MTC terminal set falls into the mobility management network element When the range indicated by the range indication information is applicable, access control is performed on the corresponding MTC terminal according to the access control indication in the access control information of the MTC terminal set.

其中，该移动性管理网元适用范围指示用于指示接入网设备在为归属于MTC终端集合的MTC终端选择那些MME时，才启用该MTC终端集合的接入控制信息对该MTC终端进行接入控制，例如可以指示MTC终端集合的接入控制信息适用于下发该MTC终端集合的接入控制信息的移动性管理网元，或可指示出该MTC终端集合的接入控制信息适用于由多个移动性管理网元组成的移动性管理网元集合(例如某个移动性管理网元池)，此时，接入网设备可关联存储该移动性管理网元(或移动性管理网元集合)的标识(例如地址、设备标识或其它标识)。MTC终端集合的接入控制信息的移动性管理网元适用范围指示信息，也可以指示出该MTC终端集合的接入控制信息适用于所有移动性管理网元，此时，接入网设备可不关联存储该移动性管理网元的标识。Wherein, the indication of the scope of application of the mobility management network element is used to instruct the access network device to enable the access control information of the MTC terminal set to access the MTC terminal when selecting those MMEs for the MTC terminal belonging to the MTC terminal set. access control, for example, it may indicate that the access control information of the MTC terminal set is applicable to the mobility management network element that issues the access control information of the MTC terminal set, or may indicate that the access control information of the MTC terminal set is applicable to the A mobility management network element set (such as a certain mobility management network element pool) composed of multiple mobility management network elements. At this time, the access network device can associate and store the mobility management network element (or mobility management network element collection) identification (such as address, device identification or other identification). The mobility management network element application scope indication information of the access control information of the MTC terminal set may also indicate that the access control information of the MTC terminal set is applicable to all mobility management network elements. At this time, the access network device may not be associated The identifier of the mobility management network element is stored.

而接入网设备在为MTC终端选择的移动性管理网元落入移动性管理网元适用范围指示信息所指示的范围时，再启用该MTC终端所属MTC终端集合的接入控制信息，此时，接入网设备按照该MTC终端集合的接入控制信息中的接入控制指示，对相应MTC终端进行接入控制。And when the mobility management network element selected for the MTC terminal falls within the range indicated by the indication information of the applicable range of the mobility management network element, the access network device then enables the access control information of the MTC terminal set to which the MTC terminal belongs, at this time , the access network device performs access control on the corresponding MTC terminal according to the access control indication in the access control information of the MTC terminal set.

其中，接入网设备若后续接收到归属于MTC终端集合的MTC终端在RRC连接建立过程中发送的消息时，便可按照保存的该MTC终端集合的接入控制信息，对该MTC终端进行接入控制。Wherein, if the access network device subsequently receives the message sent by the MTC terminal belonging to the MTC terminal set during the RRC connection establishment process, it can access the MTC terminal according to the saved access control information of the MTC terminal set. into control.

在一种应用场景下，移动性管理网元获得的MTC终端集合的接入控制信息中包含的接入控制指示可以包括：允许接入指示、禁止接入指示、延迟接入指示、允许接入时长指示、允许/禁止接入时段指示等。In one application scenario, the access control indication contained in the access control information of the MTC terminal set obtained by the mobility management network element may include: an access allowed indication, an access prohibited indication, a delayed access indication, an access allowed indication Duration indication, allow/prohibit access period indication, etc.

接入网设备例如可以按照MTC终端集合的接入控制信息中的允许接入指示，允许归属于该MTC终端集合的MTC终端接入；或，按照MTC终端集合的接入控制信息中的禁止接入指示，禁止归属该MTC终端集合的MTC终端接入；或，按照MTC终端集合的接入控制信息中的延迟接入指示，指示归属该MTC终端集合的MTC终端设定延迟时长后再进行接入；或，按照MTC终端集合的接入控制信息中的允许接入时长指示，控制归属MTC终端集合的MTC终端在的接入时长；或者，按照MTC终端集合的接入控制信息中的允许接入时段指示，指示归属该MTC终端集合的MTC终端在允许接入时段进行接入；或，按照MTC终端集合的接入控制信息中的禁止接入时段指示，指示归属该MTC终端集合的MTC终端禁止在禁止接入时段进行接入。The access network device may, for example, allow the access of the MTC terminals belonging to the MTC terminal set according to the access permission indication in the access control information of the MTC terminal set; or, according to the access prohibition in the access control information of the MTC terminal set According to the access indication, MTC terminals belonging to the MTC terminal set are prohibited from accessing; or, according to the delayed access indication in the access control information of the MTC terminal set, instruct the MTC terminals belonging to the MTC terminal set to set a delay time before connecting. or, according to the allowed access duration indication in the access control information of the MTC terminal set, control the access duration of the MTC terminals belonging to the MTC terminal set; or, according to the allowed access duration in the access control information of the MTC terminal set Indication of the access period, indicating that the MTC terminals belonging to the MTC terminal set are allowed to access during the access period; or, according to the indication of the prohibited access period in the access control information of the MTC terminal set, indicating the MTC terminals belonging to the MTC terminal set Access during prohibited access periods is prohibited.

可以理解，上述主要是以移动性管理网元下发某个MTC终端集合(例如第一MTC终端集合)的接入控制信息进行举例说明的，当然，移动性管理网元还可向接入网设备下发多个MTC终端集合的接入控制信息，接入网设备按照类似方式，根据各MTC终端集合的接入控制信息，对归属于相应MTC终端集合的MTC终端进行接入控制，而不同MTC终端集合的接入控制方式可能不同，也可能相同。It can be understood that the above is mainly illustrated by the mobility management network element issuing the access control information of a certain MTC terminal set (for example, the first MTC terminal set). Of course, the mobility management network element can also send the access control information to the access network. The device sends the access control information of multiple MTC terminal sets, and the access network device performs access control on the MTC terminals belonging to the corresponding MTC terminal set according to the access control information of each MTC terminal set in a similar manner. The access control modes of the MTC terminal set may be different or the same.

The above-mentioned access control information of the MTC terminal set is used to indicate the access control information according to the MTC terminal set. The MTC terminals in the MTC terminal set perform access control.

在一种应用场景下，分组数据网络网关可利用归属于某个MTC终端集合的MTC终端的控制面消息，通过服务网关(如SGW、SGSN等)向移动性管理网元下发该MTC终端集合的接入控制信息；或者，利用与第三方设备(例如网管系统、域名解析服务器)之间的设备级管理消息向第三方设备下发MTC终端集合的接入控制信息，通过该第三方设备向移动性管理网元下发该MTC终端集合的接入控制信息。In one application scenario, the packet data network gateway can use the control plane messages of the MTC terminals belonging to a certain MTC terminal set to issue the MTC terminal set to the mobility management network element through the serving gateway (such as SGW, SGSN, etc.) or use the device-level management message between the third-party device (such as network management system, domain name resolution server) to issue the access control information of the MTC terminal set to the third-party device, and send the MTC terminal set access control information to the third-party device through the third-party device The mobility management network element delivers the access control information of the MTC terminal set.

进一步的，移动性管理网元获得分组数据网络网关下发的MTC终端集合的接入控制信息，并可按照该MTC终端集合的接入控制信息，对归属于该MTC终端集合的MTC终端进行接入控制；或，向接入网设备下发MTC终端集合的接入控制信息，以指示该接入网设备按照MTC终端集合的接入控制信息，对归属于该MTC终端集合的MTC终端进行接入控制。Further, the mobility management network element obtains the access control information of the MTC terminal set delivered by the packet data network gateway, and can access the MTC terminals belonging to the MTC terminal set according to the access control information of the MTC terminal set. or, send the access control information of the MTC terminal set to the access network device, so as to instruct the access network device to access the MTC terminals belonging to the MTC terminal set according to the access control information of the MTC terminal set into control.

进一步的，分组数据网络网关若通过服务网关向移动性管理网元下发某个MTC终端集合(如第一MTC终端集合)的接入控制信息，分组数据网络网关还可存储服务网关的标识；分组数据网络网关例如可在负载状况变化时或从其它设备获得更新的第一MTC终端集合的接入控制信息时，根据存储的服务网关的标识，通过该服务网关更新移动性管理网元中的第一MTC终端集合的接入控制信息。或，服务网关可向分组数据网络网关上报下发了第一MTC终端集合的接入控制信息的移动性管理网元的标识，分组数据网络网关可存储服务网关上报的移动性管理网元的标识；例如可在负载状况变化时或从其它设备获得更新的第一MTC终端集合的接入控制信息时，根据存储的移动性管理网元的标识，更新移动性管理网元中的第一MTC终端集合的接入控制信息。Further, if the packet data network gateway sends the access control information of a certain MTC terminal set (such as the first MTC terminal set) to the mobility management network element through the serving gateway, the packet data network gateway can also store the identity of the serving gateway; For example, when the load condition changes or when the access control information of the first MTC terminal set is obtained from other devices, the packet data network gateway can update the mobility management network element through the serving gateway according to the stored identifier of the serving gateway.

实施例五Embodiment five

为便于更好的理解本发明实施例方案，下面主要以MTC终端b1在建立PDN连接的过程中，PGW下发负载过重指示消息，其中可携带MTC终端b1所归属的MTC终端集合(以下简称MTC终端集合A)的接入控制信息，MME在PGW发生负载过重的触发下，可将MTC终端b1所归属的MTC终端集合的接入控制信息下发给基站，指示基站按照该MTC终端集合的接入控制信息，对归属于该MTC终端集合的MTC终端进行接入控制的一种具体过程为例，对本发明实施例接入控制的实现方法的另一个实施例进行说明。In order to better understand the solution of the embodiment of the present invention, the following mainly assumes that the MTC terminal b1 is in the process of establishing a PDN connection, and the PGW sends an overload indication message, which can carry the MTC terminal set to which the MTC terminal b1 belongs (hereinafter referred to as For the access control information of the MTC terminal set A), the MME can send the access control information of the MTC terminal set to which the MTC terminal b1 belongs to the base station when the PGW is overloaded, and instructs the base station to follow the MTC terminal set Taking the access control information of the MTC terminal set as an example, a specific process of performing access control on the MTC terminals belonging to the MTC terminal set is taken as an example, and another embodiment of the implementation method of the access control in the embodiment of the present invention is described.

其中，以PGW利用MTC终端b1的控制面消息，通过SGW将MTC终端集合A的接入控制信息下发给MME为例进行说明。Wherein, the PGW uses the control plane message of the MTC terminal b1 to deliver the access control information of the MTC terminal set A to the MME through the SGW as an example for illustration.

参见图6、具体步骤可以包括：Referring to Figure 6, specific steps may include:

601、MTC终端b1向MME发起附着或者PDN连接建立请求，其中携带MTC终端b1归属的MTC终端集合A的集合标识，例如MTC终端集合A的集合标识可以包括：目的地址、使用的APN或分配的特定集合标识等。601. The MTC terminal b1 initiates an attach or PDN connection establishment request to the MME, which carries the set identifier of the MTC terminal set A to which the MTC terminal b1 belongs. For example, the set identifier of the MTC terminal set A may include: destination address, used APN or assigned A specific collection ID, etc.

602、MME向SGW发起对应MTC终端b1的建立会话请求，其中携带MTC终端集合A的集合标识；602. The MME initiates a session establishment request corresponding to the MTC terminal b1 to the SGW, which carries the set identifier of the MTC terminal set A;

603、SGW向PGW发起对应MTC终端b1的建立会话请求，其中携带MTC终端集合A的集合标识；603. The SGW initiates a session establishment request corresponding to the MTC terminal b1 to the PGW, which carries the set identifier of the MTC terminal set A;

604、PGW向SGW发送对应MTC终端b1的建立会话响应消息；604. The PGW sends a session establishment response message corresponding to the MTC terminal b1 to the SGW;

在一种应用场景下，PGW若确定MTC终端集合A(即MTC终端b1归属的MTC终端集合)的业务导致其负载过重，则PGW可在上述建立会话响应消息中携带MTC终端集合A的接入控制信息，该建立会话响应消息中携带MTC终端集合A的接入控制信息可包含接入控制指示(如允许接入时长、延迟接入时长或者禁止接入指示等)，但可不包含MTC终端集合A的集合标识，而MME可默认为该接入控制信息是MTC终端集合A的接入控制信息。该建立会话响应消息中还可携带负载过重指示，MME据此获知PGW是在负载过重时，下发的MTC终端集合A的接入控制信息。In an application scenario, if the PGW determines that the service of the MTC terminal set A (that is, the MTC terminal set to which the MTC terminal b1 belongs) causes its load to be too heavy, the PGW can carry the connection information of the MTC terminal set A in the above session establishment response message. Incoming control information, the access control information of MTC terminal set A carried in the session establishment response message may include access control indications (such as allowed access duration, delayed access duration, or prohibited access indication, etc.), but may not include MTC terminal The set ID of set A, and the MME may assume that the access control information is the access control information of set A of MTC terminals by default. The session establishment response message may also carry an indication of heavy load, so that the MME learns that the PGW is the access control information of the MTC terminal set A delivered when the load is too heavy.

PGW还可以进一步存储接收该建立会话响应消息的SGW的标识(例如地址、设备标识或其它标识)，以便于后续通过该SGW更新相应MME中的MTC终端集合A的接入控制信息。The PGW may further store the identifier (such as address, device identifier or other identifier) of the SGW receiving the session establishment response message, so as to update the access control information of the MTC terminal set A in the corresponding MME through the SGW.

其中，PGW可以通过一个或多个SGW，向一个或多个MME下发MTC终端集合A的接入控制信息，故而PGW可存储该多个SGW的标识。Wherein, the PGW can deliver the access control information of the MTC terminal set A to one or more MMEs through one or more SGWs, so the PGW can store the identities of the multiple SGWs.

605、SGW向MME转发来自PGW的建立会话响应消息；605. The SGW forwards the session establishment response message from the PGW to the MME;

进一步的，SGW还可以进一步存储接收该建立会话响应消息的MME的标识(例如地址、设备标识或其它标识)，以便于后续更新该MME中的MTC终端集合A的接入控制信息。Furthermore, the SGW may further store the identifier (such as address, device identifier or other identifier) of the MME receiving the session establishment response message, so as to update the access control information of the MTC terminal set A in the MME subsequently.

其中，SGW向多个MME下发MTC终端集合A的接入控制信息，SGW可存储下该多个MME的标识。Wherein, the SGW delivers the access control information of the MTC terminal set A to multiple MMEs, and the SGW can store the identities of the multiple MMEs.

606、MME可从来自SGW的建立会话响应消息中获得MTC终端集合A的接入控制信息，MME可进一步将该MTC终端集合A的接入控制信息下发给基站。606. The MME may obtain the access control information of the MTC terminal set A from the session establishment response message from the SGW, and the MME may further deliver the access control information of the MTC terminal set A to the base station.

607、基站获得MME下发的MTC终端集合A的接入控制信息，按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制。607. The base station obtains the access control information of the MTC terminal set A issued by the MME, and performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A.

其中，基站按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制的方式可以参照实施例二中的相关描述，此处不再赘述。Wherein, the manner in which the base station performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A may refer to the relevant description in Embodiment 2, which will not be repeated here.

此外，MME也可不向基站下发MTC终端集合A的接入控制信息，而是按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端(如MTC终端b1)进行接入控制，接入控制方式与基站的接入控制方式类似，此处不再赘述。In addition, the MME may not send the access control information of the MTC terminal set A to the base station, but, according to the access control information of the MTC terminal set A, access the MTC terminals (such as MTC terminal b1) belonging to the MTC terminal set A. Access control, the access control method is similar to the access control method of the base station, and will not be repeated here.

608、当PGW的负载减轻后(例如小于某阈值)，PGW可向此前存储了标识的SGW发送负载过重停止消息，其中可携带更新后的MTC终端集合A的接入控制信息(例如可包含集合标识和允许接入指示)。608. When the load of the PGW is reduced (for example, it is less than a certain threshold), the PGW can send an overloaded stop message to the SGW that previously stored the identifier, which can carry the updated access control information of the MTC terminal set A (for example, it can include set identification and access indication).

609、SGW向此前存储了标识的MME发送负载过重停止消息，其中携带更新后的MTC终端集合A的接入控制信息。609. The SGW sends an overload stop message to the MME that has previously stored the identifier, which carries the updated access control information of the MTC terminal set A.

在另一中实现方式中，PGW也可以不存储下发了MTC终端集合A的接入控制信息的SGW的标识，SGW也可以不存储下发了MTC终端集合A的接入控制信息MME的标识；而是由SGW在向一个或多个MME下发了MTC终端集合A的接入控制信息后，将该一个或多个MME的标识上报给PGW，PGW可存储SGW上报的MME的标识，当PGW的负载减轻后，直接向该存储了标识的一个或多个MME发送负载过重停止消息，其中可携带更新后的MTC终端集合A的接入控制信息。In another implementation, the PGW may not store the identity of the SGW that delivered the access control information of the MTC terminal set A, and the SGW may not store the identity of the MME that delivered the access control information of the MTC terminal set A ; Instead, after the SGW sends the access control information of the MTC terminal set A to one or more MMEs, it reports the identifiers of the one or more MMEs to the PGW, and the PGW can store the identifiers of the MMEs reported by the SGW. After the load of the PGW is reduced, it directly sends an overload stop message to the one or more MMEs storing the identifier, which may carry the updated access control information of the MTC terminal set A.

MME据此获知PGW负载减轻了，可向基站发送指示消息，其中携带更新后的MTC终端集合A的接入控制信息，基站更新其此前保存的MTC终端集合A的接入控制信息，按照更新后的MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制，或，MME也可直接指示基站停止使用此前保存的MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制。Based on this, the MME knows that the PGW load has been reduced, and can send an indication message to the base station, which carries the updated access control information of the MTC terminal set A. The access control information of the MTC terminal set A is used to control the access of the MTC terminals belonging to the MTC terminal set A, or the MME can also directly instruct the base station to stop using the access control information of the previously saved MTC terminal set A. The MTC terminals belonging to the MTC terminal set A perform access control.

由上技术方案可见，本实施例中MME在PGW负载过重时，获得PGW下发的某MTC终端集合的接入控制信息，进而可向基站下发该MTC终端集合的接入控制信息，指示基站根据该MTC终端集合的接入控制信息，对归属于该MTC终端进行接入控制，该机制可以实现对某些特定或所有的MTC终端进行例如接入时长、允许/禁止接入时段、禁止接入、延迟接入等接入控制，使得接入受限的MTC终端在接入网就受到相应的控制，可迅速降低PGW的负载，进而提升网络的抗风险性能。It can be seen from the above technical solution that in this embodiment, when the PGW is overloaded, the MME obtains the access control information of a certain set of MTC terminals issued by the PGW, and then can deliver the access control information of the set of MTC terminals to the base station, indicating According to the access control information of the MTC terminal set, the base station performs access control on the MTC terminals belonging to the MTC terminal. This mechanism can implement certain or all MTC terminals such as access duration, allowed/prohibited access time period, prohibited Access control, such as access and delayed access, enables MTC terminals with limited access to be subject to corresponding control on the access network, which can quickly reduce the load on the PGW, thereby improving the anti-risk performance of the network.

实施例六Embodiment six

本实施例中，PGW发生负载过重时，将负载过重消息(该消息是为设备级管理消息)发送给第三方设备。MME在为MTC终端选择PGW时，在第三方设备查询PGW的负载状态。In this embodiment, when the PGW is overloaded, it sends an overload message (the message is a device-level management message) to the third-party device. When the MME selects a PGW for the MTC terminal, it queries the load status of the PGW on the third-party device.

参见图7，具体可以包括：Referring to Figure 7, the details may include:

701、PGW若确定MTC终端集合A的业务或其它业务导致其负载过重，则PGW可通过相关接口，向第三方设备发送负载过重消息；701. If the PGW determines that the service or other services of the MTC terminal set A cause its load to be too heavy, the PGW can send a message of heavy load to the third-party device through the relevant interface;

其中，负载过重消息可携带MTC终端集合A的集合标识，还可以携带MTC终端集合A的接入控制信息(例如允许接入时长指示，禁止接入指示或延迟接入时长等)。Wherein, the overload message may carry the set ID of the MTC terminal set A, and may also carry the access control information of the MTC terminal set A (for example, an indication of the allowed access duration, an access prohibited indication, or a delayed access duration, etc.).

例如，MTC终端集合A的集合标识包括：目的地址、使用的APN或分配的特定集合标识等。第三方设备例如为网管系统或域名解析服务器等。For example, the set identifier of the MTC terminal set A includes: destination address, APN used or assigned specific set identifier, and the like. The third-party device is, for example, a network management system or a domain name resolution server.

第三方设备接收来自PGW的负载过重消息，存储MTC终端集合A的集合标识以及PGW的负载状况，还可存储MTC终端集合A的接入控制信息等信息，以备其它设备(例如MME)查询。The third-party device receives the overload message from the PGW, stores the set identifier of the MTC terminal set A and the load status of the PGW, and can also store information such as the access control information of the MTC terminal set A for other devices (such as MME) to query .

702、MME向第三方设备发送查询请求，以查询PGW的负载状况；702. The MME sends a query request to the third-party device to query the load status of the PGW;

在一种应用场景下，MME可在需要为某MTC终端选择PGW时，向第三方设备查询PGW的负载状况；In one application scenario, when the MME needs to select a PGW for an MTC terminal, it can query the load status of the PGW from a third-party device;

703、第三方设备向MME反馈查询响应。703. The third-party device feeds back a query response to the MME.

其中，若第三方设备记录PGW负载过重，则向MME反馈的查询响应，指示PGW负载过重，该查询响应还携带MTC终端集合A的集合标识。Wherein, if the third-party device records that the PGW load is too heavy, the query response fed back to the MME indicates that the PGW load is too heavy, and the query response also carries the set identifier of the MTC terminal set A.

若第三方设备还保存有MTC终端集合A的接入控制信息，则查询响应中还可携带MTC终端集合A的接入控制信息。若第三方设备并未保存有MTC终端集合A的接入控制信息，MME可根据预置的规则，生成MTC终端集合A的接入控制信息。If the third-party device also stores the access control information of the MTC terminal set A, the query response may also carry the access control information of the MTC terminal set A. If the third-party device does not store the access control information of the MTC terminal set A, the MME may generate the access control information of the MTC terminal set A according to preset rules.

MME获得MTC终端集合A的接入控制信息后，进一步下发给基站，以指示基站按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制。基站后续按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制的方式可以参照实施例二中的相关描述，此处不再赘述。After the MME obtains the access control information of the MTC terminal set A, it further sends it to the base station to instruct the base station to perform access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A. For the manner in which the base station subsequently performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A, reference may be made to the relevant description in Embodiment 2, which will not be repeated here.

此外，MME也可不向基站下发MTC终端集合A的接入控制信息，而是按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制，接入控制方式与基站的接入控制方式类似，此处不再赘述。In addition, the MME may not deliver the access control information of the MTC terminal set A to the base station, but performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A, and the access control The method is similar to the access control method of the base station, and will not be repeated here.

可以理解，上述是以对PGW向MME下发MTC终端集合A的接入控制信息进行举例说明的，当然，PGW可向MME下发多个MTC终端集合的接入控制信息，MME按照类似方式，根据各MTC终端集合的接入控制信息，对归属于相应MTC终端集合的MTC终端进行接入控制或下发给接入网设备，而不同MTC终端集合的接入控制方式可能不同，也可能相同。It can be understood that the above is an example of the PGW delivering the access control information of the MTC terminal set A to the MME. Of course, the PGW can deliver the access control information of multiple MTC terminal sets to the MME. The MME follows a similar method. According to the access control information of each MTC terminal set, access control is performed on the MTC terminals belonging to the corresponding MTC terminal set or delivered to the access network equipment, and the access control methods of different MTC terminal sets may be different or the same .

由上技术方案可见，本实施例中MME在需要为MTC终端选择PGW时，从第三方设备(例如为网管系统或域名解析服务器)查询PGW的负载情况，并获得MTC终端集合的接入控制信息，进而可向基站下发该MTC终端集合的接入控制信息，指示基站根据该MTC终端集合的接入控制信息，对归属于该MTC终端进行接入控制，该机制可以实现对某些特定或所有的MTC终端进行例如接入时长、允许/禁止接入时段、禁止接入、延迟接入等接入控制，使得接入受限的MTC终端在接入网就受到相应的控制，可迅速降低PGW的负载，进而提升网络的抗风险性能。It can be seen from the above technical solution that in this embodiment, when the MME needs to select a PGW for an MTC terminal, it queries the load status of the PGW from a third-party device (such as a network management system or a domain name resolution server) and obtains access control information for a set of MTC terminals , and then can send the access control information of the MTC terminal set to the base station, and instruct the base station to perform access control on the MTC terminals belonging to the MTC terminal according to the access control information of the MTC terminal set. All MTC terminals perform access control such as access duration, allowed/prohibited access period, prohibited access, delayed access, etc., so that MTC terminals with restricted access are subject to corresponding control in the access network, which can be quickly reduced. PGW load, thereby improving the anti-risk performance of the network.

例如，MTC终端集合A的集合标识包括：目的地址、使用的APN或分配的特定集合标识等。第三方设备例如为SGW或网管系统等。For example, the set identifier of the MTC terminal set A includes: destination address, APN used or assigned specific set identifier, and the like. The third-party device is, for example, an SGW or a network management system.

802、第三方设备向MME发送PGW负载过重消息(设备级管理消息)，其中可携带MTC终端集合A的标识，还可以携带MTC终端集合A的接入控制信息、PGW负载过重指示。802. The third-party device sends a PGW overload message (device-level management message) to the MME, which may carry the identifier of the MTC terminal set A, and may also carry the access control information of the MTC terminal set A and the PGW overload indication.

在一种应用场景下，第三方设备(例如SGW或者网管系统)可以向所有与其有接口的MME发送PGW负载过重消息，或者基于配置信息，向特定的一个或多个MME发送PGW负载过重消息，或者，根据MTC终端集合A的集合标识(目的地址、使用的APN或分配的特定集合标识)，向正在与归属于MTC终端集合A的MTC终端进行业务的MME发送PGW负载过重消息。In one application scenario, a third-party device (such as SGW or network management system) can send a PGW overload message to all MMEs that have interfaces with it, or send a PGW overload message to one or more specific MMEs based on configuration information. message, or, according to the set identity of the MTC terminal set A (destination address, APN used or assigned specific set identity), send a PGW overload message to the MME that is conducting business with the MTC terminals belonging to the MTC terminal set A.

若PGW负载过重消息携带MTC终端集合A的集合标识，但没携带MTC终端集合A的接入控制信息，则MME接收到PGW负载过重消息后，可以基于预置的规则，生成MTC终端集合A的接入控制信息(例如允许接入时长指示、禁止接入指示或延迟接入时长指示)。若PGW负载过重消息携带有MTC终端集合A的接入控制信息，则MME可直接从该PGW的负载过重消息中获得MTC终端集合A的接入控制信息。If the PGW overload message carries the set identifier of the MTC terminal set A, but does not carry the access control information of the MTC terminal set A, after receiving the PGW overload message, the MME can generate an MTC terminal set based on preset rules A's access control information (for example, an indication of an allowed access time period, an indication of a prohibited access time period, or an indication of a delayed access time period). If the PGW overload message carries the access control information of the MTC terminal set A, the MME can directly obtain the access control information of the MTC terminal set A from the PGW overload message.

进一步的，MME可在获得MTC终端集合A的接入控制信息后，进一步下发给基站，指示基站按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制。基站后续按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制的方式可以参照实施例二中的相关描述，此处不再赘述。Further, after obtaining the access control information of the MTC terminal set A, the MME can further send it to the base station, instructing the base station to access the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A control. For the manner in which the base station subsequently performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A, reference may be made to the relevant description in Embodiment 2, which will not be repeated here.

此外，MME也可不向基站下发MTC终端集合A的接入控制信息，而是按照MTC终端集合A的接入控制信息，对归属于MTC终端集合A的MTC终端进行接入控制，接入控制方式与基站的接入控制方式类似，此处不再赘述。In addition, the MME may not deliver the access control information of the MTC terminal set A to the base station, but performs access control on the MTC terminals belonging to the MTC terminal set A according to the access control information of the MTC terminal set A, and the access control The method is similar to the access control method of the base station, and will not be repeated here.

可以理解，上述是以对PGW向MME下发MTC终端集合A的接入控制信息进行举例说明的，当然，PGW可向MME下发多个MTC终端集合的接入控制信息，MME按照类似方式，根据各MTC终端集合的接入控制信息，对归属于相应MTC终端集合的MTC终端进行接入控制或下发给接入网设备，而不同MTC终端集合的接入控制方式可能不同，也可能相同。It can be understood that the above is an example of the PGW delivering the access control information of the MTC terminal set A to the MME. Of course, the PGW can deliver the access control information of multiple MTC terminal sets to the MME. The MME follows a similar method. According to the access control information of each MTC terminal set, access control is performed on the MTC terminals belonging to the corresponding MTC terminal set or delivered to the access network equipment, and the access control methods of different MTC terminal sets may be different or the same .

由上可见，本实施例中PGW可在负载过重时，通过第三方设备(例如SGW或网管系统)向相关的MME下发负载过重消息，MME获得MTC终端集合的接入控制信息，进而可向基站下发该MTC终端集合的接入控制信息，指示该基站根据该MTC终端集合的接入控制信息，对归属于该MTC终端进行接入控制，该机制可以实现对某些特定或所有的MTC终端进行例如接入时长、允许/禁止接入时段、禁止接入、延迟接入等接入控制，使得接入受限的MTC终端在接入网就受到相应的控制，可迅速降低PGW的信令负载过重程度，进而提升网络的抗风险性能。It can be seen from the above that in this embodiment, when the load is too heavy, the PGW can send a load overload message to the relevant MME through a third-party device (such as SGW or network management system), and the MME obtains the access control information of the MTC terminal set, and then The access control information of the MTC terminal set can be issued to the base station, indicating that the base station performs access control on the MTC terminals belonging to the MTC terminal according to the access control information of the MTC terminal set. MTC terminals perform access control such as access duration, allowed/denied access period, prohibited access, delayed access, etc., so that MTC terminals with restricted access are subject to corresponding control in the access network, which can quickly reduce PGW The signaling load is too heavy, thereby improving the anti-risk performance of the network.
