背景技术
多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)是一种由一个数据源向多个用户发送信息的点到多点服务，为具有相同服务需求的用户同时提供服务，从而网络资源得到共享。因此，MBMS是一种高效的信息分配方案，有效节省了日益紧张的无线资源。多播服务的订阅是通过用户和网络之间的信令交互实现的，也就是说，用户与网络之间建立连接，通知网络侧接收某广播内容，从而加入群组。
现有技术的群组通信(Group Communication Service，GCS)***中，第三方应用服务器通过MB2接口与运营商网络多媒体广播服务中心(Broadcast Multicast service center，BMSC)连接，并获知运营商网络的网络传输能力。第三方应用服务器仅根据运营商网络BMSC的网络传输能力，确定业务数据采用单播传输方式或者多播传输方式，使得网络资源并不能得到充分利用，从而造成了网络资源的浪费。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
应理解，本发明实施例的技术方案可以应用于各种通信***，例如：全球移动通讯(Global System of Mobile communication，GSM)***、码分多址(Code Division Multiple Access，CDMA)***、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)***、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)***、LTE频分双工(Frequency Division Duplex，FDD)***、LTE时分双工(Time Division Duplex，TDD)、通用移动通信***(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信***等。
还应理解，在本发明实施例中，用户设备(User Equipment，UE)可称之为终端设备(Terminal)、移动台(Mobile Station，MS)、移动终端(Mobile  Terminal)等，该用户设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，例如，用户设备可以是移动电话(或称为“蜂窝电话”)、具有移动终端的计算机等，例如，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。
在本发明实施例中，基站可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，本发明并不限定。为方便描述，本发明实施例中，上述为终端提供无线通信功能的装置统称为基站或BS。
LTE的制定和设计用以实现低运营成本、低时延、高***容量、用户数据速率和高功率利用率等。演进的多媒体广播多播服务时3GPP推出的对现有多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)的补充。
图1示出了本发明实施例LTE***中MBMS***的架构图。该MBMS***包括的网元及设备有用户设备(User Equipment，UE)、演进的通用移动通信***陆地无线接入网(Evolved Universal Mobile Telecommunications System Territorial Radio Access Network，E-UTRAN)、移动性管理网元(Mobility Management Entity，MME)、MBMS网关(Gateway，GW)、多媒体广播服务中心(Broadcast Multicast service center，BMSC)、分组数据网络(Packet Data Network，PDN)网关和内容提供商(Content Provider)。
其中，UE用于支持MBMS承载业务的激活和去激活功能。E-UTRAN用于实现与无线演进网络有关的功能，传送MBMS数据到制定的MBMS服务区。
MME负责控制面的移动性管理，如用户上下文和移动状态管理以及分配用户临时身份标识等。
PDN网关作为IP多播传输的登陆点，是3GPP接入网络和非接入网络之间的用户面锚点，和外部PDN的接口。
MBMS GW，提供MBMS GW与BM SC之间的控制面SGmb接口，以及提供MBMS GW与BM SC间的用户面SGi-mb接口。SGi-mb接口的MBMS会话业务数据进行通用分组无线服务隧道协议用户平面(General Packet  Radio Service Tunneling Protocol User Plane，GTPU)封装，并在M1接口进行组播分发到演进型基站(evolved Node B，eNB)，提供组播目的IP地址分配，以及M1传输的控制面(C-TEID)分配功能，支持组播相关的协议，即IPV4网络支持组播管理协议(IGMPv3)和PIM，IPV6网络支持组播侦听者发现协议(MLDv2)和协议无关的组播协议(PIM)。
BMSC，用来保存签约数据，生成计费记录，成员管理(Gi接口)，确定MBMS会话传输的时间表；确定MBMS会话重传的时间表，标识每个MBMS会话，分配TMGIs；并且通知UE该TMGI，UE收到TMGI后，在该TMGI标识的传输通道上接收到广播业务。
Content Provider:提供广播的内容，可以是不属于运营商的第三方的内容提供商，比如视频业务提供商或者电视节目提供商等。
需要说明的是，本发明实施例也可以用于通用陆地无线接入网(Universal Terrestrial Radio Access Network，简称UTRAN)或全球移动通信***(Global System for Mobile Communications，简称GSM)/GSM演进增强数据速率(Enhanced Data Rates for GSM Evolution，简称EDGE)无线接入网(GSM/EDGE Radio Access Network，简称GERAN)中。与LTE网络不同的是，在UTRAN或GERAN中，MME的功能是由GPRS业务支持节点(Service GPRS Supporting Node，SGSN)完成的，而且服务网关(Serving Gateway，SGW)或分组数据网(Packet Data Network，PDN)网关(PDN Gateway，PGW)的功能是由网关GPRS支持节点(Gateway GPRS Support Node，简称GGSN)完成的。
图2为3GPP网络中能力开放的架构图。3GPP网络可以将网络能力开放给互联网应用(Over The Top，OTT)提供商。具体地，网络能力包括通信能力，签约信息、UE上下文信息和控制功能等。其中，通信能力主要有声音呼叫(voice calling)，短讯服务(Short Messaging Service，SMS)和多媒体短信服务(Multimedia Messaging Service，MMS)等。UE签约信息主要有订阅身份(Subscription identity)、特征集(feature sets)和优先权(preference)等。UE上下文信息主要有位置信息(location)，控制功能(例如，服务质量(Qaulity of Service，QoS)规则)等。
为了将3GPP网络的相关信息向第三方应用服务器(3rd Application)开放出去，引入一个逻辑功能实体，服务能力开放功能(Service Capability  Exposure Function，SCEF)，该逻辑功能与***架构演进(System Architecture Evolution，SAE)网络的网元设备有接口。SCEF的上层是应用(Application)层，即第三方应用服务器。第三方应用服务器可以与SCEF建立连接，3GPP网络可以将信息通过SCEF发送给第三方应用服务器，第三方应用服务器也可以通过SCEF发送信息给3GPP网络。
如图2所示，能力开放功能单元(Service Capability Exposure Function，SCEF)处于3GPP和业务能力服务器(service capability server，SCS)/应用服务器(Application Server，AS)之间。该3GPP网络包括归属地签约用户服务器(Home Subscriber Service，HSS)模块、策略与计费制定功能(Policy and Charging Rule Function，PCRF)模块、MME/SGSN、BMSC、机器类型通信互通功能(Machine Type Communication InterWorking Function，MTC-IWF)模块、服务呼叫会话控制功能(Serving Call Session Control Function，S-CSCF)模块、无线接入网拥塞感知功能(RAN Congestion Awareness Function，RCAF)以及网络实体等。在eMBMS***架构中，Content provider也属于一种AS。具体地，AS可以通过API函数向SCEF发起业务能力请求或者AS直接向网络实体发起请求，SCEF从3GPP网络获取对应的网络能力，再通过API发送给SCS/AS。
如图3为现有技术中多播方式的传输流程。其中，多播传输是指从一个数据源向特定区域内的多个用户同时发送数据。具体地，在当前的标准协议中(TS23.682)，SCS/AS通过SCEF广播方式进行群组消息传送，具体流程如图3所示。
101、SCS/AS向SCEF发送临时移动组标识(Temporary Mobile Group Identity，TMGI)请求消息；
102、通过SCEF与HSS/归属位置寄存器(Home Location Register，HLR)之间的授权；
103、通过BMSC配置该TMGI标识；
104、SCEF向SCS/AS返回TMGI响应消息；
105、建立UE与SCS/AS的应用连接；
106、SCS/AS向SCEF发送请求组消息；
107、建立HSS/HLR与SCEF之间的授权；
108、SCEF向BMSC发送激活MBMS承载请求消息；
109、BMSC向SCEF返回激活MBMS承载响应消息；
110、SCEF向SCS/AS发送确认组消息；
111、建立MBMS-GW/GGSN MME/SGSN与RAN之间的会话连接；
112、从而SCS/AS能够通过SCEF、BMSC、RAN向UE发送组消息；
113、UE接收到该组消息后，发送响应组消息。
图4为现有技术的群组通信(Group Communication Service，GCS)***的示意图。群组通信业务应用服务器(GCS AS)也可以认为是一种第三方应用服务器，GCS AS通过MB2接口与BMSC连接。因此，第三方应用服务器提供商必须改造网络支持MB2接口(例如，部署直径(Diameter)协议栈等工作)，这样会给现有广泛存在的大量OTT(即第三方应用服务器)带来升级以及网络部署的复杂性。
该群组通信***中，第三方应用服务器需要获知运营商网络的网络传输能力，对第三方应用服务器的部署的有较高需求。此外，第三方应用服务器根据网络传输能力确定业务数据采用多播传输方式或单播传输方式，并没有考虑终端设备的位置信息或者业务需求等，造成网络资源的浪费。
应理解，在本发明实施例中，服务器可以内容提供商，用于提供广播内容。服务器可以是不属于运营商的第三方的内容提供商，例如，OTT。OTT是指通过互联网向用户提供各种应用服务。这种应用和目前运营商所提供的通信业务不同，它仅利用运营商的网络，而服务由运营商之外的第三方提供。目前，典型的OTT业务有互联网电视业务、视频业务。为描述方便，本发明实施例以SCS/AS例进行描述，但本发明并不限于此。
图5示出了根据本申请一个实施例的业务处理的方法的交互流程图。本申请实施例中的各种术语的含义与前述各实施例相同。
应注意，这只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
501、服务器确定第一业务请求消息。
该第一业务请求消息用于确认传输模式，本发明对该第一业务请求消息的名称不进行限定，换句话说，其他具有该功能的消息、信息等也在本发明保护的范围之内。
可选地，该方法还包括：该服务器获取终端设备的标识信息和/或该终端设备的业务需求信息；其中，该服务器确定第一业务请求消息包括：该服务 器确定该第一业务请求消息，该第一业务请求消息携带该终端设备的标识信息和/或该终端设备的业务需求信息。
具体而言，该业务需求信息可以是业务内容的标识，例如，UE与SCS/AS建立连接的过程中，SCS/AS可以获知UE的标识信息以及该UE对应的业务内容的标识。或者，UE可以主动通知SCS/AS对业务数据的需求等。这样，SCS/AS就可以获知该UE需求哪种类型的业务数据。
