本发明涉及家庭基站接入网络的技术，尤其涉及一种家庭基站自动接入网络的方法及系统。The present invention relates to a technology for accessing a network by a home base station, in particular to a method and a system for automatically connecting a home base station to a network.
背景技术Background technique
家庭基站在不同的标准组织中的称呼不同，在第三代合作合作伙伴计划(3GPP，Third Generation Partnership Project)标准组织中称为家庭网络节点B(HNB，Home Node B)/演进的家庭网络节点B(HeNB，Home Evolved Node B)，其中，3G中的家庭基站称为HNB，长期演进(LTE，Long Term Evolution)系统的家庭基站称为HeNB，而在3GPP2等其它标准组织中称为Femto，Femto也是对所有类型家庭基站的统称。实际上，上述家庭基站的本质是相同的，均是用于提供微微小区的、小型的、低功率的蜂窝基站，主要用于家庭及办公室等室内场所。家庭基站的作用是作为蜂窝网在室内覆盖的补充，为用户提供话音及数据服务。Femtocells are called differently in different standard organizations, and they are called Home Network Node B (HNB, Home Node B)/evolved home network node in the Third Generation Partnership Project (3GPP, Third Generation Partnership Project) standard organization B (HeNB, Home Evolved Node B), among them, the home base station in 3G is called HNB, the home base station of Long Term Evolution (LTE, Long Term Evolution) system is called HeNB, and it is called Femto in other standard organizations such as 3GPP2, Femto is also a general term for all types of femtocells. In fact, the essence of the aforementioned femtocells is the same, they are all small, low-power cellular base stations for providing picocells, and are mainly used in indoor places such as homes and offices. The role of the home base station is to provide users with voice and data services as a supplement to the indoor coverage of the cellular network.
Femto Cell概念最早由英国Ubiquisys公司提出，源于3G初期覆盖的不足以及无线保真(Wi-Fi，Wireless Fidelity)技术的挑战。在3G发展初期，网络建设重点主要是室外，用户在室内的通信需求往往无法很好地满足。尤其是近年来Wi-Fi技术的迅速普及、以及Wi-Fi/蜂窝网双模手机的不断增多，3G话音及数据业务都有被分流的危险。在这种情况下，Femto Cell概念一经推出，就受到来自移动运营商的追捧。The concept of Femto Cell was first proposed by Ubiquisys, a British company, due to the lack of initial coverage of 3G and the challenges of Wireless Fidelity (Wi-Fi, Wireless Fidelity) technology. In the initial stage of 3G development, the focus of network construction was mainly outdoors, and the communication needs of users indoors were often not well met. Especially in recent years, with the rapid popularization of Wi-Fi technology and the increasing number of Wi-Fi/cellular network dual-mode mobile phones, 3G voice and data services are in danger of being diverted. In this case, once the concept of Femto Cell was launched, it was sought after by mobile operators.
Femto Cell通过用户已有的非对称数字用户环路(ADSL，AsymmetricDigital Subscriber Line)、局域网(LAN，Local Area Network)等宽带电路连接，远端由专用网关实现从IP网到移动网的连接，能自动完成配置并且自动开始工作。同时，Femto Cell还是实现固定移动融合的一种新技术，是实现混合移动融合(FMC，Fixed Mobile Convergence)的最好途径，帮助移动运营商最大化其利益，减少对蜂窝/Wi-Fi双模手机的依赖，提供差异化服务。在固定移动融合趋势日益增强的今天，Femto Cell的发展更加成为产业界关注的焦点。图1为包含HeNB的演进的UMTS陆地无线接入网络(E-UTRAN，Evolved-UMTS(Universal Mobile Telecommunications System)Terrestrial Radio AccessNetwork)的结构示意图，如图1所示，E-UTRAN由接入网元和基站组成，其中，接入网关包括移动管理实体(MME，Mobile Management Entity)/服务网关(S-GW，Serving Gateway)，基站包括宏基站(eNB)和家庭基站，家庭基站通过家庭基站网关(HeNB GW)而接入接入网元中。基站之间通过X2接口连接，基站与接入网关之间通过S1接口连接，家庭基站与家庭基站网关之间以及家庭基站网关与接入网元之间均通过S1接口连接。The Femto Cell is connected through broadband circuits such as the existing asymmetric digital subscriber line (ADSL, Asymmetric Digital Subscriber Line) and local area network (LAN, Local Area Network). Configuration is done automatically and work starts automatically. At the same time, Femto Cell is also a new technology to realize fixed mobile convergence. It is the best way to realize fixed mobile convergence (FMC, Fixed Mobile Convergence), helping mobile operators maximize their benefits and reduce the need for cellular/Wi-Fi dual-mode Reliance on mobile phones to provide differentiated services. Today, the trend of fixed-mobile convergence is increasing, and the development of Femto Cell has become the focus of attention of the industry. Figure 1 is a schematic structural diagram of an evolved UMTS terrestrial radio access network (E-UTRAN, Evolved-UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network) including HeNB. As shown in Figure 1, E-UTRAN consists of access network elements Composed of a base station, wherein the access gateway includes a mobile management entity (MME, Mobile Management Entity)/serving gateway (S-GW, Serving Gateway), the base station includes a macro base station (eNB) and a home base station, and the home base station passes through the home base station gateway ( HeNB GW) and access to the access network element. The base stations are connected through the X2 interface, the base station and the access gateway are connected through the S1 interface, and the home base station and the home base station gateway and between the home base station gateway and the access network element are connected through the S1 interface.
由于Femto的即插即用特点，势必对现有网络的运行会造成不必要的干扰，因此，在载频的选择上，需要尽可能的降低对现有网络的干扰。而且，由于无线载频资源是非常宝贵的资源，运营商在不同的区域可使用的载频也是不尽相同的，用户的Femto的即插即用的移动性，在载频的选取上，对运营商而言，必须是可控的，以避免触犯当地的法律。Due to the plug-and-play feature of Femto, it will inevitably cause unnecessary interference to the operation of the existing network. Therefore, in the selection of the carrier frequency, it is necessary to reduce the interference to the existing network as much as possible. Moreover, since wireless carrier frequency resources are very precious resources, the carrier frequencies that operators can use in different areas are also different. The plug-and-play mobility of the user's Femto, in terms of carrier frequency selection, is very important to As far as operators are concerned, it must be controllable to avoid violating local laws.
Femto设备的接入，目的是为移动终端提供相应的移动业务的服务，解决盲点覆盖和运营商移动业务的延伸等问题。移动业务的延伸问题的提出，要求Femto设备具备一定的移动性和即插即用的特性，那么，对Femto设备的并网运行，提出一系列的控制要求，包括：Femto的自动网络接入、设备的注册鉴权并网运行、设备参数配置等等。The purpose of the access of Femto equipment is to provide corresponding mobile service services for mobile terminals, and solve problems such as blind spot coverage and extension of mobile service of operators. The extension of mobile services requires Femto equipment to have certain mobility and plug-and-play features. Then, a series of control requirements are put forward for the grid-connected operation of Femto equipment, including: Femto automatic network access, Device registration and authentication, grid-connected operation, device parameter configuration, etc.
因此，设备是需要并入运营商当前网络运营的，为了避免设备接入的随意性，保证网络运行的可靠性，Femto设备的接入，必须要有一整套的鉴权注册机制，以保证通信的稳定，避免无序的混乱状态。Femto在不同区域的接入，或者Femto用户对设备的控制，需要考虑到用户的控制权限等级问题，不同等级的用户，在不同的区域内，对设备的参数具有不同的控制等级。Therefore, the device needs to be integrated into the current network operation of the operator. In order to avoid the randomness of device access and ensure the reliability of network operation, the access of Femto devices must have a complete set of authentication and registration mechanisms to ensure communication. Stable and avoid disorderly chaos. Femto access in different areas, or Femto users' control of equipment, needs to consider the user's control authority level. Users of different levels have different control levels for equipment parameters in different areas.
遗憾的是，目前并没有相应的技术方案可用。Unfortunately, there is currently no corresponding technical solution available.

本发明的基本思想为：在家庭基站上电后，能根据自身的配置信息接入到网络侧，接入到网络侧后，家庭基站同时将自身的注册数据发送给网络侧，网络侧根据家庭基站的注册数据为接入的家庭基站进行无线资源等配置，从而实现了家庭基站到网络侧的自动接入。本发明的家庭基站接入网络侧更灵活方便，很好地能满足了网络侧的无线配置要求。The basic idea of the present invention is: after the home base station is powered on, it can access the network side according to its own configuration information.

为使本发明的目的、技术方案和优点更加清楚明白，以下举实施例并参照附图，对本发明进一步详细说明。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail by citing the following embodiments and referring to the accompanying drawings.
实施例一Embodiment one
家庭基站在上电后，根据固化在家庭基站中的家庭基站管理服务器地址或者连接于家庭基站上的即插即用数字设备中存储的地址与网络侧的家庭基站管理服务器建立通信链路。图2为本发明家庭基站接入网络的方法实施例一的流程图，如图2所示，本示例家庭基站接入网络的方法包括以下步骤：After the Femtocell is powered on, a communication link is established with the Femtocell management server on the network side according to the Femtocell management server address fixed in the Femtocell or the address stored in the plug-and-play digital device connected to the Femtocell. Fig. 2 is a flow chart of Embodiment 1 of a method for accessing a network by a home base station according to the present invention. As shown in Fig. 2, the method for accessing the network by a home base station in this example includes the following steps:
步骤201：家庭基站Femto向家庭基站管理服务器(EMS)发送注册请求消息。注册请求消息中携带家庭基站的注册数据，注册数据包括Femto的接入位置信息、鉴权信息等，接入位置信息可以为：Femto所在的地理位置信息，比如全球定位系统(GPS，Global Positioning System)参数；Femto接入网络由相关的服务运营商提供的IP地址信息；Femto接入网络的通信端口信息。Step 201: the Femto of the home base station sends a registration request message to the management server (EMS) of the home base station. The registration request message carries the registration data of the home base station. The registration data includes Femto access location information, authentication information, etc. The access location information can be: the geographic location information of the Femto, such as the Global Positioning System (GPS, Global Positioning System ) parameters; Femto access network IP address information provided by relevant service operators; Femto access network communication port information.
鉴权信息包括家庭基站的注册鉴权密钥，该鉴权密钥可以存储于与家庭基站连接的外部即插即用数字设备中，通过数字设备来提供注册鉴权密钥。在数字设备中，可附带的存储其他信息，如家庭基站管理服务器接入端口地址信息，家庭基站管理服务器接入端口地址可不唯一，Femto根据接入端口的列表，选取相应的接入端口，建立与Femto的通信链路。The authentication information includes a registration authentication key of the home base station, which can be stored in an external plug-and-play digital device connected to the home base station, and the registration authentication key is provided by the digital device. In the digital device, other information can be stored additionally, such as the address information of the access port of the home base station management server. The address of the access port of the home base station management server may not be unique. Femto selects the corresponding access port according to the list of access ports, and establishes Communication link with Femto.
步骤202：EMS对Femto进行鉴权，鉴权通过则指示Femto与HeNBGW/MME之间发起S1连接建立指示，否则结束当前流程。EMS根据用户注册鉴权密钥和接入位置信息，判决是否允许家庭基站接入，如果鉴权通过，则指示Femto与HeNB GW/MME之间发起S1连接建立指示；否则，拒绝Femto接入HeNB GW/MME，当前处理流程结束。Step 202: The EMS authenticates the Femto, and if the authentication passes, it instructs the Femto to initiate an S1 connection establishment instruction between the HeNBGW/MME, otherwise, ends the current process. EMS judges whether to allow Femto to access according to the user registration authentication key and access location information. If the authentication is passed, it instructs Femto to initiate an S1 connection establishment instruction between HeNB GW/MME; otherwise, rejects Femto to access HeNB GW/MME, the current processing flow ends.
步骤203：Femto与HeNB GW/MME之间完成S1连接建立后，通知EMS。Step 203: after the establishment of the S1 connection between the Femto and the HeNB GW/MME is completed, the EMS is notified.
步骤204：EMS收到Femto的S1口链路建立完成消息后，向Femto发送激活命令。EMS收到Femto的S1口链路建立完成消息后，进入激活Femto无线链路流程，向Femto发送激活命令。使Femto完成接入网络操作。在Femto完成参数配置前，Femto不具备无线发射能力。上述的激活命令中包括注册载频列表和免费载频列表，以及载频选择的指示策略等。Step 204: The EMS sends an activation command to the Femto after receiving the Femto's S1 interface link establishment completion message. After receiving the Femto's S1 port link establishment completion message, the EMS enters the process of activating the Femto wireless link and sends an activation command to the Femto. Let Femto complete the operation of accessing the network. Before the femto completes the parameter configuration, the femto does not have the wireless transmission capability. The above-mentioned activation command includes a list of registered carrier frequencies, a list of free carrier frequencies, and an instruction strategy for carrier frequency selection.
本发明中，运营商为注册的Femto维护两个可用的载频列表，分别对应注册载频列表和免费公共载频列表。其中注册载频列表中的载频为运营商在某个区域内注册购买的载频资源，而免费载频列表为当前区域内可被免费使用的载频资源，比如由国际电信联盟无点点通信标准化部门(ITU-R，InternationalTelecommunications Union-Radio communication Standardization Sector)定义的工业、科学和医疗(ISM，Industrial、Scientific and Medical、)频段。需要说明的是，在不同区域，所能够使用的免费载频是不尽相同的。In the present invention, the operator maintains two available carrier frequency lists for the registered Femto, corresponding to the registered carrier frequency list and the free public carrier frequency list respectively. Among them, the carrier frequency in the registered carrier frequency list is the carrier frequency resource registered and purchased by the operator in a certain area, and the free carrier frequency list is the carrier frequency resource that can be used for free in the current area. Industrial, scientific and medical (ISM, Industrial, Scientific and Medical,) frequency bands defined by the standardization department (ITU-R, International Telecommunications Union-Radio communication Standardization Sector). It should be noted that in different regions, the free carrier frequencies that can be used are not the same.
本发明中，可以在Femto设备事先存储历史载频，即该Femto事先被配置的工作载频。或者，Femto向EMS发送注册数据时，将历史载频信息通知给EMS。In the present invention, the historical carrier frequency, that is, the previously configured working carrier frequency of the Femto, can be stored in the Femto device. Or, when the Femto sends the registration data to the EMS, it notifies the EMS of the historical carrier frequency information.
EMS根据Femto的激活请求消息中携带的区域位置数据，判定Femto所处的区域，当家庭基站当前的所在区域为用户注册区域，那么在发送给Femto的激活许可消息中携带当前区域的注册载频信息列表。用户注册区域即当前不能使用免费载频的区域。如果Femto在发起激活请求消息中携带的历史载频在当前区域可用，那么，在EMS发送给Femto的激活许可消息中的载频列表中，将历史载频排在载频列表的最前面。这样，Femto可能将历史载频选为Femto的工作载频。The EMS determines the area where the Femto is located according to the area location data carried in the Femto activation request message. When the current area where the home base station is located is the user registration area, the registration carrier frequency of the current area is carried in the activation permission message sent to the Femto. Information List. The user registration area is the area where the free carrier frequency cannot be used currently. If the historical carrier frequency carried by the Femto in the activation request message is available in the current area, then in the carrier frequency list in the activation permission message sent by the EMS to the Femto, the historical carrier frequency is placed at the top of the carrier frequency list. In this way, Femto may select the historical carrier frequency as the working carrier frequency of Femto.
与载频列表一起发送给Femto的，还包括指示Femto进行载频选择的指示策略等。The information sent to the Femto together with the carrier frequency list also includes an indication strategy for instructing the Femto to select a carrier frequency.
步骤205：Femto在接收到载频列表数据后，根据EMS的指示选取合适的载频。选取载频的方式可以有3类方式，采用哪种方式，由EMS在激活许可消息中指示载频选择的指示策略来指示。Step 205: After receiving the carrier frequency list data, the Femto selects a suitable carrier frequency according to the instructions of the EMS. There are three types of ways to select the carrier frequency, and which way to use is indicated by the indication policy of carrier frequency selection indicated by the EMS in the activation permission message.
列表中最优载频自动选择，Femto根据相关规则，选择最优载频作为注册载频，并反馈给EMS。最优载频，即能满足Femto无线通信的最佳的载频，例如前述的历史载频等。例如，也可以基于干扰最小准则，即Femto在相关载频上扫描接收电平，将接收电平作为干扰准则，电平越大，干扰越大，电平越小，干扰越小。如果EMS在激活许可消息中，携带了干扰电平门限数据，那么Femto将以门限判决准则作为载频选择依据。The optimal carrier frequency in the list is automatically selected, and Femto selects the optimal carrier frequency as the registered carrier frequency according to relevant rules, and feeds back to EMS. The optimal carrier frequency refers to the optimal carrier frequency that can satisfy Femto wireless communication, such as the aforementioned historical carrier frequency. For example, it can also be based on the minimum interference criterion, that is, the Femto scans the receiving level on the relevant carrier frequency, and uses the receiving level as the interference criterion. The larger the level, the greater the interference, and the smaller the level, the smaller the interference. If the EMS carries interference level threshold data in the activation permission message, then Femto will use the threshold decision criterion as the basis for carrier frequency selection.
或者，将载频列表中第一个满足需求载频自动选择为Femto的工作载频，Femto根据相关判决准则，在列表中依次判决相关载频，第一个满足相关准则的载频，作为工作载频，反馈给EMS。Alternatively, the first carrier frequency that meets the requirements in the carrier frequency list is automatically selected as the working carrier frequency of Femto. Carrier frequency, fed back to EMS.
或者，将相关载频信息显示在人机交互界面上，由用户人工选择Femto的工作载频。Alternatively, the relevant carrier frequency information is displayed on the man-machine interaction interface, and the user manually selects the working carrier frequency of the Femto.
步骤206：Femto将选定的工作载频信息通知EMS。当Femto选定载频后，在激活反馈消息中携带载频信息，告知EMS选定的工作载频信息。当Femto选定载频后，完成Femto的激活流程，在EMS接收到Femto的激活反馈消息后，开始处理Femto的相关参数配置流程，在Femto参数完成配置前，Femto不具备无线发送能力。Step 206: Femto notifies EMS of the selected working carrier frequency information. After the Femto selects the carrier frequency, it carries the carrier frequency information in the activation feedback message and informs the EMS of the selected working carrier frequency information. After the Femto selects the carrier frequency, the Femto activation process is completed. After the EMS receives the Femto activation feedback message, it starts to process the Femto related parameter configuration process. Before the Femto parameter configuration is completed, the Femto does not have the wireless transmission capability.
实施例二Embodiment two
本实施例中，家庭基站在注册激活过程中，需要向家庭基站管理服务器提供的注册鉴权密钥和其他的相关信息，家庭基站管理服务器根据这些信息判决家庭基站是否具备接入网络提供无线服务的能力。In this embodiment, during the registration and activation process of the home base station, the home base station needs to provide the registration authentication key and other related information to the home base station management server, and the home base station management server judges whether the home base station has access to the network to provide wireless services Ability.
图3为本发明家庭基站接入网络的方法实施例二的流程图，如图3所示，本示例家庭基站接入网络的方法包括以下步骤：Fig. 3 is a flowchart of Embodiment 2 of a method for accessing a network by a home base station according to the present invention. As shown in Fig. 3, the method for accessing the network by a home base station in this example includes the following steps:
步骤301：家庭基站Femto向家庭基站管理服务器(EMS)发送注册请求消息。家庭基站上电后，根据外部即插即用数字设备中存储的用户鉴权密钥，向家庭基站管理服务器发起注册接入请求，向家庭基站管理服务器提供用户鉴权密钥和设备接入端口信息。Step 301: the Femto of the home base station sends a registration request message to the management server (EMS) of the home base station. After the Femtocell is powered on, according to the user authentication key stored in the external plug-and-play digital device, it initiates a registration access request to the Femtocell management server, and provides the Femtocell management server with the user authentication key and device access port information.
本示例中，家庭基站中未存储有网络侧的接入端口信息，家庭基站上电后，根据当前的接入网关端口与家庭基站管理服务器建立连接。In this example, the home base station does not store access port information on the network side. After the home base station is powered on, it establishes a connection with the home base station management server according to the current access gateway port.
上述家庭基站用户的注册数据中，包含了如下信息：家庭基站用户鉴权密钥、家庭基站服务封闭用户列表、家庭基站注册地接入端口列表或家庭基站是否允许在注册端口以外端口接入判决信息；用户鉴权密钥事先存储于家庭基站中或连接于家庭基站的数据设备中。家庭基站服务封闭用户列表：在列表中存储了默认允许接入家庭基站提供服务覆盖区域的用户终端设备，除此以外的移动终端设备，需要根据家庭基站的当前状态来决定，当家庭基站为封闭状态时，仅仅允许列表中的移动终端接入，当家庭基站为开放状态时，除允许列表中的移动终端外，允许运营商网络注册的其他用户接入，当家庭基站为混合状态时，除允许列表中的移动终端外，还允许家庭基站管理员设置的临时移动终端接入。家庭基站注册地接入端口列表：家庭基站注册接入端口信息为允许设备默认接入的端口。家庭基站是否允许在注册端口以外端口接入判决信息：当用户注册为允许在注册端口以外接入时，家庭基站可在任意网络接入端口接入并被激活。The registration data of the above-mentioned home base station user includes the following information: the home base station user authentication key, the list of closed users of the home base station service, the access port list of the home base station registration, or whether the home base station is allowed to access through ports other than the registered port Information; the user authentication key is pre-stored in the home base station or in a data device connected to the home base station. Femtocell service closed user list: The user terminal equipment that is allowed to access the service coverage area provided by the Femtocell by default is stored in the list. Other mobile terminal devices need to be determined according to the current state of the Femtocell. When the Femtocell is closed In the state, only the mobile terminals in the list are allowed to access. When the home base station is in the open state, except for the mobile terminals in the allowed list, other users registered with the operator network are allowed to access. When the home base station is in the mixed state, except In addition to the mobile terminals in the allowed list, temporary mobile terminals set by the home base station administrator are also allowed to access. Femtocell registration access port list: The Femtocell registration access port information is the port that the device is allowed to access by default. Judgment information on whether the Femtocell allows access on ports other than the registered port: When the user registers to allow access to the port other than the registered port, the Femtocell can be accessed and activated on any network access port.
步骤302：家庭基站管理服务器接收到家庭基站的注册激活请求后，根据注册密钥，判决设备是否允许接入网络，如果家庭基站的接入端口为注册端口，那么设备接入鉴权流程结束，允许用户设备接入；如果家庭基站的接入端口为非注册端口，那么判决用户注册信息中是否允许设备在非注册端口接入，如果为允许，那么设备接入鉴权流程结束，允许设备接入，否则，不允许用户设备接入。当Femto完成激活载频配置后，由EMS完成后继的参数配置和网络接入方面的操作流程。Step 302: After receiving the registration activation request of the home base station, the home base station management server determines whether the device is allowed to access the network according to the registration key. If the access port of the home base station is a registration port, the device access authentication process ends. Allow user equipment to access; if the access port of the home base station is a non-registered port, then determine whether the user registration information allows the device to access through the non-registered port, if it is allowed, then the device access authentication process ends, and the device is allowed to access Otherwise, the user equipment is not allowed to access. After the Femto completes the active carrier configuration, the EMS completes the subsequent parameter configuration and network access operation procedures.
Femto完成激活流程后，Femto设备和EMS之间确定了载频选择，Femto在EMS的指导下，完成网络接入操作，具备无线发送接收能力。After Femto completes the activation process, the carrier frequency selection is determined between Femto equipment and EMS. Under the guidance of EMS, Femto completes the network access operation and has wireless transmission and reception capabilities.
步骤303：EMS根据Femto上报的载频选择和位置区域信息，确定Femto与HeNB GW/MME的网络接入点，EMS根据Femto上报的区域位置信息，确定Femto的最佳的HeNB GW/MME的网络接入点，建立Femto和HeNBGW/MME之间的S1-C/U连接。然后，EMS根据Femto上报的载频选择和位置区域信息以及用户的注册签约信息，确定无线参数配置策略，例如Femto的发射功率的范围，在Femto的服务范围内，终端的最大发射功率。EMS根据Femto上报的位置区域信息、载频、用户的注册签约信息，确定用户可控的无线参数的类别，当无线参数可控时，需要确定参数可控的范围，在不通的场景下，参数可控的范围是不相同的。对于用户可控的无线参数，Femto可提供人机交互界面，向用户显示可控参数的类别，对于可控的参数，人机交互界面可向用户显示控制范围。当EMS参数控制下达给Femto后，无论Femto自动配置参数还是在用户干预情况下的参数配置，Femto都需要向EMS反馈配置结果，参数配置成功包括与HeNB GW/MME之间建立连接和所有的设备参数配置成功。Step 303: EMS determines the network access point between Femto and HeNB GW/MME according to the carrier frequency selection and location area information reported by Femto, and EMS determines the best HeNB GW/MME network of Femto according to the area location information reported by Femto The access point establishes the S1-C/U connection between the Femto and the HeNBGW/MME. Then, the EMS determines the wireless parameter configuration strategy based on the carrier frequency selection and location area information reported by the Femto and the user's registration and subscription information, such as the range of the Femto's transmit power, and the maximum transmit power of the terminal within the Femto's service range. According to the location area information, carrier frequency, and user registration and subscription information reported by Femto, the EMS determines the type of wireless parameters controllable by the user. When the wireless parameters are controllable, it is necessary to determine the controllable range of the parameters. The controllable range is not the same. For user-controllable wireless parameters, Femto can provide a human-computer interaction interface to display the category of controllable parameters to the user. For controllable parameters, the human-computer interaction interface can display the control range to the user. When the EMS parameter control is issued to Femto, no matter Femto automatically configures parameters or parameter configuration under user intervention, Femto needs to feed back the configuration results to EMS. Successful parameter configuration includes establishing a connection with HeNB GW/MME and all devices The parameter configuration is successful.
本发明中，在Femto运行过程中，允许用户修改Femto相关参数，修改完成后，需要和EMS之间进行确认。In the present invention, during the running process of Femto, the user is allowed to modify relevant parameters of Femto, and after the modification is completed, confirmation with EMS is required.
本发明中，EMS还可以根据Femto所选择接入HeNB GW/MME的接入接口确定Femto的工作模式，具体的，在所述家庭基站所选取的工作载频为免费载频时，所述网络侧确定所述家庭基站为开放模式，允许所有用户终端接入；所述家庭基站所选取的工作载频为收费载频时，所述网络侧确定所述家庭基站为封闭模式，仅允许授权用户终端接入。当EMS为Femto确定的工作模式与Femto本来的工作模式冲突时，以EMS为Femto确定的工作模式为准。In the present invention, the EMS can also determine the working mode of the Femto according to the access interface selected by the Femto to access the HeNB GW/MME. Specifically, when the working carrier frequency selected by the home base station is a free carrier frequency, the network The side determines that the home base station is in an open mode, allowing all user terminals to access; when the working carrier frequency selected by the home base station is a charging carrier frequency, the network side determines that the home base station is in a closed mode, allowing only authorized users Terminal access. When the working mode determined by EMS for Femto conflicts with the original working mode of Femto, the working mode determined by EMS for Femto shall prevail.
