通知用户设备业务结束的方法Method for Notifying User Equipment of End of Service

技术领域technical field

本发明涉及多媒体广播和组播业务(简称MBMS)，特别涉及通知用户设备业务结束的方法。The present invention relates to multimedia broadcast and multicast service (referred to as MBMS), in particular to a method for notifying user equipment of service end.

背景技术Background technique

多媒体广播和组播业务是由第三代伙伴计划(简称3GPP)提出并正在进行标准化的一项新业务。MBMS业务是一种单向的点对多点的业务，这种业务的最大特点是它可以有效的利用无线资源和网络资源。The multimedia broadcast and multicast service is a new service proposed by the Third Generation Partnership Project (abbreviated as 3GPP) and being standardized. The MBMS service is a one-way point-to-multipoint service. The biggest feature of this service is that it can effectively utilize wireless resources and network resources.

为了更好的对本发明进行说明，图1描述了MBMS的系统结构。下面是对图1MBMS系统结构的描述：In order to better illustrate the present invention, Fig. 1 describes the system structure of MBMS. The following is a description of the MBMS system structure in Figure 1:

MBMS网络结构以通用分组无线业务(简称GPRS)核心网为基础，并增加了新的网络单元。101广播和组播业务中心(简称BM-SC)是MBMS系统的业务控制中心。102网关GPRS支持节点(简称GGSN)和103服务GPRS支持节点(简称SGSN)构成了MBMS业务的传输网络，为数据的传输提供路由。106归属位置寄存器(简称HLR)保存与用户有关的数据，可以提供用户鉴权等服务。104 UMTS陆地无线接入网(简称UTRAN)在空中接口上为MBMS服务提供无线资源。107 Iu表示无线接入网和核心网之间的接口。105用户设备(简称UE)是用来接收数据的终端设备。MBMS业务所用的无线资源不是用户专用的，而是由此业务的所有用户共享的。The MBMS network structure is based on the general packet radio service (referred to as GPRS) core network, and adds new network elements. 101 The broadcast and multicast service center (BM-SC for short) is the service control center of the MBMS system. 102 Gateway GPRS Support Node (GGSN for short) and 103 Serving GPRS Support Node (SGSN for short) constitute a transmission network for MBMS services and provide routes for data transmission. 106 The Home Location Register (HLR for short) saves data related to the user and can provide services such as user authentication. 104 UMTS Terrestrial Radio Access Network (abbreviated as UTRAN) provides radio resources for MBMS services on the air interface. 107 Iu represents the interface between the radio access network and the core network. 105 User equipment (UE for short) is a terminal device for receiving data. The radio resources used by MBMS services are not dedicated to users, but shared by all users of this service.

根据现有的MBMS业务的定义，一个MBMS业务可以由几个会话组成。对于每一个会话，当会话开始时，网络会通过寻呼唤醒UE并统计UE数目，决定无线承载类型(点对点的无线承载或点对多点的无线承载)以及相关的参数。当会话结束时，网络要通知UE，UE可以释放相关的用户平面的资源，停止监听有关业务信道。现有技术定义了在网络中通知会话开始和结束的方法。According to the definition of the existing MBMS service, an MBMS service may consist of several sessions. For each session, when the session starts, the network wakes up the UE through paging, counts the number of UEs, and determines the radio bearer type (point-to-point radio bearer or point-to-multipoint radio bearer) and related parameters. When the session ends, the network should notify the UE, and the UE can release the relevant user plane resources and stop monitoring the relevant traffic channel. The prior art defines methods for announcing session start and end in the network.

另外，在现有技术中，UE离开一个业务组采用的是点对点的方式。In addition, in the prior art, the UE leaves a service group in a point-to-point manner.

图2描述了现有技术中UE发起的离开MBMS业务的方法。Fig. 2 describes a method for leaving an MBMS service initiated by a UE in the prior art.

在201阶段，UE决定不再继续接收MBMS业务，而通过非接入层(简称NAS)消息“MBMS上下文去激活请求”向网络发出请求。In stage 201, the UE decides not to continue to receive the MBMS service, but sends a request to the network through a Non-Access Stratum (NAS for short) message "MBMS Context Deactivation Request".

在202阶段，SGSN向UE发出响应消息“MBMS上下文去激活接受”。UE收到响应消息后，可以释放与MBMS业务有关的资源，停止接收MBMS信道。In stage 202, the SGSN sends a response message "MBMS Context Deactivation Accept" to the UE. After receiving the response message, the UE can release resources related to the MBMS service and stop receiving MBMS channels.

图3描述了现有技术中，网络发起的UE离开MBMS业务的方法。Fig. 3 describes a method for a UE to leave an MBMS service initiated by a network in the prior art.

在301阶段，SGSN决定要停止某个UE的MBMS业务接收过程，它向UE发送NAS消息“MBMS上下文去激活请求”。In stage 301, the SGSN decides to stop the MBMS service receiving process of a certain UE, and it sends a NAS message "MBMS Context Deactivation Request" to the UE.

在302阶段，UE收到SGSN的请求后，应立即释放有关的MBMS资源，停止接收MBMS业务，并向SGSN回复“MBMS上下文去激活接受”消息。In stage 302, after receiving the request from the SGSN, the UE should immediately release the relevant MBMS resources, stop receiving MBMS services, and reply to the SGSN with a "MBMS context deactivation accept" message.

由上面的描述可以看到，现有技术中UE离开MBMS业务组的方法都是以点对点的方式进行的。在现有技术中，网络通知UE离开一个业务都是以点对点的方式进行的，需要UE和网络之间的交互来完成。但是，当MBMS业务终止时，所有的UE都需要离开MBMS业务，这时如果采用现有的技术，UE和网络之间首先需要建立点到点的RRC连接，以完成UE和SGSN之间点对点的信令交互。当用户数目很多时，这样做必然造成严重的网络拥塞。另外一方面，因为有些UE是在空闲模式下接收MBMS业务的，为了离开MBMS业务而建立RRC连接，也是不科学的。It can be seen from the above description that in the prior art, the methods for the UE to leave the MBMS service group are all performed in a point-to-point manner. In the prior art, the network notifies the UE to leave a service in a point-to-point manner, which requires interaction between the UE and the network. However, when the MBMS service is terminated, all UEs need to leave the MBMS service. At this time, if the existing technology is used, a point-to-point RRC connection needs to be established between the UE and the network to complete the point-to-point connection between the UE and the SGSN. Signaling interaction. When the number of users is large, doing so will inevitably cause serious network congestion. On the other hand, because some UEs receive MBMS services in idle mode, it is unscientific to establish an RRC connection in order to leave MBMS services.

发明内容Contents of the invention

本发明的目的是提供一种通知用户设备业务结束的新方法。The purpose of the present invention is to provide a new method for notifying user equipment of service termination.

为实现上述目的，一种通知用户设备业务结束的方法，包括步骤：In order to achieve the above purpose, a method for notifying user equipment of the end of service includes steps:

UE离开一个业务组的方法。Method for UE to leave a service group.

在401阶段，RNC收到SGSN发来的“业务停止”消息，知道某个MBMS业务要结束了。Instage 401, the RNC receives a "service stop" message from the SGSN and knows that a certain MBMS service is about to end.

在402阶段，RNC立即停止有关的MBMS信道的发送，释放有关的控制平面和用户平面的资源，并释放这个业务的MBMS上下文。Instage 402, the RNC immediately stops the transmission of the relevant MBMS channel, releases the resources of the relevant control plane and user plane, and releases the MBMS context of this service.

在403阶段，RNC向UE发送“对话结束”消息，通知UE这是该MBMS业务的最后一次会话，或包含一个“业务停止指示”来指示UE该MBMS业务已经终止。Instage 403, the RNC sends a "session end" message to the UE, informing the UE that this is the last session of the MBMS service, or includes a "service stop indication" to indicate to the UE that the MBMS service has terminated.

作为403阶段的替代方案，在404阶段，RNC可以向UE直接发送“业务停止指示”消息，来指示一个MBMS业务已经终止。As an alternative tostep 403, instep 404, the RNC may directly send a "service stop indication" message to the UE to indicate that an MBMS service has terminated.

在405阶段，UE在本地释放有关的MBMS的控制平面和用户平面的资源，停止接收有关MBMS信道，并最终释放这个MBMS业务的业务上下文。Instage 405, the UE locally releases related MBMS control plane and user plane resources, stops receiving related MBMS channels, and finally releases the service context of the MBMS service.

图5描述了本发明中RNC的节点处理流程。Fig. 5 describes the node processing flow of RNC in the present invention.

501阶段表示RNC从SGSN接收信息。Stage 501 indicates that the RNC receives information from the SGSN.

502阶段判断从上述SGSN接收到的信息是否是关于业务停止的信息，如果是，则向503移动，如果不是则返回501，继续接收其它消息。Instage 502, it is judged whether the information received from the above SGSN is information about service suspension, if yes, then move to 503, if not, return to 501, and continue to receive other messages.

图5中的503阶段表示RNC释放有关MBMS业务的资源，包括用户平面和控制平面的资源，删除它保存的该MBMS业务的业务上下文。Stage 503 in Fig. 5 indicates that RNC releases resources related to MBMS services, including user plane and control plane resources, and deletes the service context of the MBMS service it has saved.

在504阶段，RNC组织发到UE的消息，用于通知UE某个MBMS业务已经结束。发送这个消息所采用的信道可以是现有信道，也可以是为MBMS新定义的信道，如MCCH。Instage 504, the RNC organizes a message to the UE to notify the UE that a certain MBMS service has ended. The channel used to send this message can be an existing channel, or a channel newly defined for MBMS, such as MCCH.

图6描述了本发明中UE的节点处理流程。Fig. 6 describes the node processing flow of the UE in the present invention.

图6的601阶段表示UE从RNC接收消息。Stage 601 in FIG. 6 indicates that the UE receives a message from the RNC.

602阶段判断从上述RNC接收到的消息是否是有关对话停止的信息，如果是则移向603，如果不是则移向606。Instage 602, it is judged whether the message received from the above-mentioned RNC is information about the cessation of the dialogue, if yes, then move to 603, if not, then move to 606.

603阶段判断在602阶段接收到的消息中是否包含业务停止的有关信息，如果是则移向605，如果不是则移向604，UE只需释放有关的用户平面的资源，由于此阶段与本发明没有密切的关系，此处不做更详细的描述。Instage 603, it is judged whether the message received instage 602 contains relevant information of service stop, if yes, then move to 605, if not, then move to 604, the UE only needs to release the relevant user plane resources, since this stage is related to the present invention No close relationship, no more detailed description here.

在605阶段，因为业务已经结束，UE在本地释放有关此MBMS业务的所有资源，包括控制平面和用户平面的资源，停止接收有关MBMS的信道，删除保存的MBMS业务上下文，并通知UE的高层。Instage 605, because the service has ended, UE locally releases all resources related to the MBMS service, including resources on the control plane and user plane, stops receiving related MBMS channels, deletes the saved MBMS service context, and notifies the upper layers of the UE.

606阶段用于判断UE接收到的消息是否为“业务停止指示”，如果是则转向605阶段继续处理，如果不是，则转向601阶段继续接收其它消息。Step 606 is used to judge whether the message received by the UE is a "service stop indication", if yes, go to step 605 to continue processing, if not, go to step 601 to continue receiving other messages.

图7描述了本发明中UE内部协议层之间的通信以及操作流程。Fig. 7 describes the communication and operation flow between UE internal protocol layers in the present invention.

在UE实体内部，与网络进行通信的协议大致可以分为四层，分别是如图7所示的701非接入层，702RRC层，703RLC/MAC层，704是物理层。非接入层是与无线接入功能无关的协议层，它负责用户与接入层之间的信息转换，RRC层，RLC/MAC层和物理层都属于接入层，负责处理与无线接入有关的功能，包括无线信道的配置与处理等，RRC层负责无线资源控制，空中接口上的信令消息就是在由这一层解释和分析的，RLC/MAC层属于数据链路层，负责数据送到物理层传输前的一些准备工作，物理层负责实际数据的无线发送。在空中接口上UE最先从物理层接收来自网络的消息，然后逐级向上传送，非接入层消息由非接入层解释并处理，接入层消息由接入层解释并处理。RRC层可以通过706控制原语对RLC/MAC层和物理层进行配置。Inside the UE entity, the protocol for communicating with the network can be roughly divided into four layers, which are 701 non-access layer, 702 RRC layer, 703 RLC/MAC layer, and 704 physical layer as shown in FIG. 7 . The non-access layer is a protocol layer that has nothing to do with the wireless access function. It is responsible for the information conversion between the user and the access layer. The RRC layer, the RLC/MAC layer and the physical layer all belong to the access layer and are responsible for processing and wireless access. Relevant functions, including wireless channel configuration and processing, etc., the RRC layer is responsible for radio resource control, and the signaling messages on the air interface are interpreted and analyzed by this layer. The RLC/MAC layer belongs to the data link layer and is responsible for data Some preparatory work before sending to the physical layer for transmission, the physical layer is responsible for the wireless transmission of actual data. On the air interface, the UE first receives messages from the network from the physical layer, and then transmits them upward step by step. The non-access layer messages are interpreted and processed by the non-access layer, and the access layer messages are interpreted and processed by the access layer. The RRC layer can configure the RLC/MAC layer and the physical layer through 706 control primitives.

在本发明中，在如图7所示的708阶段，UE从SRNC接收到有关“业务结束指示”的信息，在707阶段，首先物理层通过RLC/MAC层把这个消息传送到RRC层，由于这个消息是接入层消息，RRC层将处理这个消息，RRC层的工作包括以下几方面的内容：In the present invention, at stage 708 as shown in Figure 7, UE receives information about "service end indication" from SRNC, at stage 707, at first the physical layer transmits this message to the RRC layer through the RLC/MAC layer, because This message is an access layer message, and the RRC layer will process this message. The work of the RRC layer includes the following aspects:

1)RRC层检查与通知的MBMS业务相关的上下文，在确认业务结束后，要删除此业务的上下文。1) The RRC layer checks the context related to the notified MBMS service, and deletes the context of the service after confirming the end of the service.

2)RRC层通过706控制接入点向RLC/MAC层和物理层发送控制原语，配置与此MBMS业务有关的无线接入参数，释放与此MBMS业务相关的信道所占用的资源，让物理层停止接收与此MBMS业务相关的信道。2) The RRC layer controls the access point to send control primitives to the RLC/MAC layer and the physical layer through 706, configures wireless access parameters related to the MBMS service, releases resources occupied by channels related to the MBMS service, and allows physical The layer stops receiving channels related to this MBMS service.

3)RRC层要把业务结束指示信息传送给非接入层。3) The RRC layer should transmit the service end indication information to the non-access layer.

非接入层在得知业务结束后，要把存贮的与此业务有关的信息删除，并以合适的方式通知用户。After the non-access layer learns that the service is over, it should delete the stored information related to the service and notify the user in a suitable way.
