Description

背景技术
移动通信国际标准组织第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)定义了组通信业务应用服务器(GCS AS)如何使用3GPP***提供的组通信业务使能装置(GCSE)来为组通信业务(GCS)提供架构以及保障GCS的连续性。
当用户设备(UE，User Equipment)或网元检测到UE移出了多媒体广播多播业务(MBMS，Multimedia Broadcast Multicast Service)覆盖范围且能够接收单播递送时，所述UE先同时接收MBMS递送方式和单播递送方式发送的数据，然后再中断接收MBMS递送方式发送的数据，只接收单播递送方式发送的数据，以保障从MBMS递送方式切换到单播递送方式时所述GCS的连续性。
在从MBMS递送方式切换到单播递送方式的过程里，一次GCS中，所述GCSE根据不同的递送方式分别触发计费消息并生成对应的离线计费话单(CDR)，如：所述GCSE中的演进的分组核心网(EPC，Evolved Packet Core)的核心网元分组数据网络网关(P-GW，PDN Gateway)为单播递送方式触发计费消息生成P-GW的CDR，而所述GCSE中的MBMS的核心网元广播组播业务中心(BM-SC，Broadcast Multicast-Service Centre)为MBMS递送方式触发计费消息生成BM-SC的CDR，但是如何将所述GCSE中的各网元，如P-GW、BM-SC等生成的CDR做针对同一次GCS的计费 关联，尚未有明确的方法。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明。
图1为实现GCS的非漫游架构的结构示意图；如图1所示，所述应用 域中的GCS AS通常由第三方来提供；而虚线左边的部分为3GPP***提供的GCSE，所述GCSE中包括：家乡签约服务器(HSS，Home Subscriber Server)、PCRF、移动管理实体(MME，Mobility Management Entity)、服务网关(S-GW，Serving Gateway)/P-GW、UE、演进的通用陆基无线接入网(E-UTRAN，evolved universal terrestrial radio access network)、广播组播业务网关(MBMS-GW)、BM-SC，其中，上述设备之间的交互通过设备之间连接线上的对应型号的接口实现；
图2为从单播递送切换到MBMS递送时GCS保持连续性的实现流程示意图；如图2所示，所述方法包括：
步骤201：当UE进行组中的会话(Ongoing Group Session)时，即UE进行组通信业务时，GCS AS通过GC1接口通知UE；
此时，MBMS递送(MBMS Delivery)方式可行并告知对应MBMS承载业务的临时移动组标识(TMGI，Temporary Mobile Group Identifier)；
步骤202：UE通过单播递送(Unicast Delivery)方式接收GCS AS发送的单播下行数据(DL data over unicast)；
步骤203：UE检测到已经进入MBMS覆盖区域，并开始从MTCH接收数据，即接收MBMS调度信息；所述MBMS调度信息来自MBMS承载的数据对应多播业务信道(MTCH)上的TMGI；
步骤:204：UE通过MBMS递送方式接收GCS AS发送的广播组播下行数据(DL data over MBMS)；
步骤:205：UE同时通过单播和MBMS接收GCS AS发送的下行数据；
步骤:206：UE通知GCS AS停止发送单播数据流(UE notifies GCSE AS to stop sending unicast flow)；
具体地，UE通知GCS AS自己在MBMS覆盖下并且接收到了对应于TMGI的MBMS承载业务，此时，GCS AS停止通过单播递送方式发送下 行数据给UE，随后，UE只通过MBMS递送方式接收GCS AS发送的下行数据。
类似图2的步骤中，当UE或网元检测到UE移出了MBMS覆盖范围并可以接收单播递送时，在这个切换过程里，UE也可以同时接收MBMS递送方式和单播递送方式发送的下行数据，然后再中断接收MBMS递送方式发送的下行数据，只接收单播递送方式发送的的下行数据，以从MBMS delivery切换到Unicast delivery时保障业务的连续性。
在上述递送方式切换的过程里，GCSE分别将触发计费消息并生成对应的CDR，如：EPC的核心网元P-GW为单播递送触发计费消息生成P-GW的CDR，而MBMS的网元BM-SC为MBMS递送方式触发计费消息生成BM-SC的CDR，但是如何将GCSE中不同的网元(如：P-GW，BM-SC等)生成的CDR做针对同一次GCS的计费关联尚未有明确的方法。
这里，所述P-GW的CDR里存在外部计费标识信息(External Charging Identifier)，且允许非EPC中的网元将生成的计费标识发送至P-GW；具体的传递方式可以借助策略控制和计费(PCC)架构中由第三方AS(GCS AS可以看作一种第三方AS)通过Rx接口将相关信息包括计费标识等传递给PCRF，再由PCRF通过Gx接口将信息传给P-GW。例如，3GPP规范TS23.203定义的PCC架构的示意图，如图3所示，所述PCC架构包括：签约属性资料库(SPR，Subscription Profile Repository)、应用功能(AF，Application Function)、在线计费***(OCS，Online Charging System)、PCRF、承载绑定和事件报告功能(BBERF，Bearing Binding and Event Report Function)、流量检测功能(TDF，Traffic Detection Function)、策略和计费执行功能(PCEF，Policy and Charging Enforcement Function)、离线计费***(OF CS，Offline Charging System)、网关(Gateway)；所述网关包括P-GW；其中，上述设备之间的交互通过设备之间连接线上的对应型号的接 口实现；所述PCC架构为P-GW从非EPC中的网元(如第三方应用服务器)获取外部计费标识信息提供了解决方案；如图3所示，AF可以看作是一种第三方应用服务器(如：GCS AS等)，策略和PCRF通过Rx接口接收来自AF的信息，其中，所述信息包括：外部计费标识、第三方应用提供者标识以及第三方应用标识等，并将所述PCRF通过Gx接口将外部计费标识、第三方应用提供者标识以及第三方应用标识等传递给P-GW，如此，所述P-GW的CDR里就含有了外部计费标识、第三方应用提供者标识以及第三方应用标识等信息；但是，所述MBMS中的网元不产生任何计费标识信息，也不获取非MBMS中的网元的计费标识信息。因此，对于同一次GCS，保障GCS的连续性同时，所述P-GW为单播递送生成的CDR和所述BM-SC为MBMS递送生成的CDR无法做相应的计费关联，从而无法对UE和/或第三方应用服务器(AS)进行有效的计费和对账。
