Description

一种视频分发方法和设备 技术领域
本发明涉及通信领域，尤其涉及一种视频分发方法和设备。
背景技术
OTT(Over The Top)是指互联网公司越过运营商，发展基于开放互联网的各种视频及数据服务业务，即仅利用运营商的网络传输能力，而服务由运营商之外的第三方提供互联网电视业务等。
在现有业务和能力开放(Service Exposure and Enablement Support，SEES)技术中，OTT第三方(例如搜狐视频、乐视电视、百度浏览器和腾讯微信等)可利用网络的传输能力向第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)网络提供数据请求的时间段、在特定区域发送的数据量、服务质量(Quality of Service，QoS)和优先级等，3GPP网络根据OTT第三方的请求将特定数据按照网络授权的QoS和优先级在特定区域进行发送，并向OTT第三方提供推荐的时间段、计费策略信息、网络异常信息和用户设备(User Equipment，UE)的状态信息等。
对于运营商支持OTT视频的情况，3GPP网络具备的多媒体广播多播服务(Multimedia Broadcast Multicast Service，MBMS)支持能力：包括媒体格式的支持、媒体分发、缓存/转码能力以及广告插入能力都未在现有的3GPP网络能力开放框架中涉及。这样对于运营商来说，运营商需要和每个OTT第三方进行互通测试和开发定制视频支持能力，对于OTT第三方而言，由于每个运营商都存在不同的MBMS能力，如果OTT第三方不利用3GPP网络具备的MBMS视频支持能力，OTT第三方也需要和每个运营商进行互通测试，适配不同的运营商管道和不同终端的视频支持能力，这样会增加OTT第三方的IOT(Inter-Operability Testing，互操作性测试)工作量，视频分发和管理负荷重。
发明内容
本发明实施例提供一种视频分发方法和设备，能够解决运营商将MBMS的媒体能力开放给OTT第三方工作量大、管理复杂以及OTT第三方通过移动网络分发视频时IOT工作量大、视频分发和管理负荷重的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例可以应用于演进分组系统(Evolved Packet System，EPS)下的多媒体广播多播服务MBMS架构，该MBMS是一种点到多点的业务，可以实现数据从单个实体到多个接收者之间的传输，可以包括以以下网元和设备：
UE，支持MBMS承载业务的激活/去激活功能；
分组数据网络网关(Packet Data Network Gateway，P-GW)，是3GPP接入网络和非3GPP接入网络之间的用户面锚点，和外部分组数据网络的接口；
多媒体广播服务中心(Broadcast Multicast Service Center，BM-SC)，用来生成计费记录、成员管理、MBMS会话和传输管理、业务通告管理、MBMS传输安全支持、确定MBMS会话传输和重传的时间表、标识每个MBMS会话、分配临时移动组标识(Temporary Mobile Group Identity，TMGI)、发起或终止MBMS承载资源、发送 MBMS数据并具有错误回弹策略等；
在能力开放架构中，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)/第三方服务器(Application Server，AS)之间，SCS/AS可通过应用程序编程接口(Application Program Interface，API)向SCEF发起业务能力请求或者SCS/AS直接向网络实体发起请求。SCEF从3GPP网络请求对应的网络能力，SCEF再将获取的网络能力/结果通过API发送给SCS/AS。对于广播能力开放，SCEF通过接口与BM-SC相连，AS也通过该接口请求分配/释放TMGI，激活/去激活/修改MBMS承载，BM-SC通过该接口将MBMS状态信息通报给AS。
基于上述MBMS架构和能力开放架构，本发明实施例提供一种视频分发方法，如图1所示，包括：
101、SCEF接收第三方服务器发送的第一请求消息，第一请求消息包括第三方服务器请求用于视频分发的多媒体广播多播服务MBMS能力协商参数。
对于运营商来说，第三方服务器可称为上述SCS/AS，对于用户来说，第三方服务器可称为OTT视频服务器，为用户提供视频内容。
在SCEF接收到第三方服务器发送的第一请求消息之前，可以是由于UE先访问OTT视频服务器，OTT视频服务器检测到至少两个UE访问相同的视频内容后，OTT视频服务器和3GPP的SCEF交互，向SCEF发送第一请求消息请求调用3GPP网络的MBMS视频支持能力，该第一请求消息携带OTT服务器请求用于视频分发的MBMS能力协商参数，例如视频内容的传输模式指示、MBMS的安全特性指示、支持内容缓冲指示或不支持内容缓冲指示等。
也可以是OTT视频服务器预先向3GPP网络请求MBMS能力开放资源，从而向SCEF发送的第一请求消息，这样在OTT视频服务器接收到至少两个UE访问相同的视频内容时，可将UE的请求重定 向到广播接收模式接收视频内容。
或者第三方服务器预先配置有策略信息，当第三方服务器接收到UE发送的HTTP请求时便向SCEF发送第一请求消息，本申请不做限定。
第一请求消息还可以包括第三方服务器的端口信息以及第三方服务器的媒体编码信息。第三方服务器的端口信息用于第三方服务器与BM-SC之间的信任通道数据传输；媒体编码信息包括视频编码信息、音频编码信息、文本编码信息和图片编码信息中的至少一个。
102、SCEF根据第一请求消息向归属地签约用户服务器HSS发送第二请求消息，以向HSS请求开放MBMS能力。
SCEF将第一请求消息中的MBMS能力协商参数和/或MBMS媒体能力开放请求指示携带在第二请求消息中发送给归属地签约用户服务器(Home Subscriber Server，HSS)，MBMS媒体能力开放请求指示用于请求HSS开放MBMS管道能力，HSS便可检查与运营商的签约信息，确定是否允许开放MBMS能力给OTT第三方，如果HSS进行MBMS能力判定，则例如判定是否开放MBMS管道能力、是否开放媒体能力(包括内容缓存、媒体转码能力等)以及是否开放广告插入能力等。
103、SCEF在接收到HSS确定允许MBMS能力开放时返回的第二响应消息时，向BM-SC发送第三请求消息，以请求获取BM-SC开放的第一MBMS能力信息。
当HSS确定开放MBMS能力时，向SCEF返回第二响应消息，以表征准许开放MBMB能力给OTT第三方。若第二请求消息包括MBMS能力协商参数，则在HSS允许开放MBMS能力时，第二响应消息包括HSS根据HSS与运营商的签约信息和MBMS能力协商参数确定开放的第二MBMS能力信息；若第二响应消息包括第二MBMS能力信息，则第三请求消息还包括第二MBMS能力信息，也就是说，BM-SC是根据HSS确定的第二MBMS能力信息与BM-SC 与运营商的签约信息确定的第一MBMS能力信息。
若第二请求消息包括MBMS媒体能力开放请求指示，则第二响应消息包括MBMS能力开放请求指示，MBMS能力开放请求指示用于请求BM-SC确定开放的第一MBMS能力信息。此时，若第二请求消息还包括MBMS能力协商参数，那么第二响应消息中的第一MBMS能力信息便是BM-SC根据HSS确定的第二MBMS能力信息确定的；若第二响应消息未包括第二MBMS能力信息，则第三请求消息还包括MBMS能力协商参数，也就是HSS不做MBMS能力判定，只是在HSS确定允许开放MBMS能力的情况下，直接由BM-SC根据MBMS能力协商参数与运营商的签约信息确定开放的第一MBMS能力信息。
其中，MBMS能力协商参数、第一MBMS能力信息和第二MBMS能力信息分别包括视频内容的传输模式指示、使用MBMS的安全特性指示、内容转码能力支持指示、内容缓冲指示、体验质量QoE上报指示、网络信息上报指示、广告消费信息指示和广告插入能力指示中的至少一个；其中，传输模式指示为广播模式、或广播/单播混合模式、或动态广播/单播模式；安全特性指示为打开状态或关闭状态；内容转码能力支持指示为支持转码指示或不支持转码指示；内容缓冲指示为支持内容缓冲指示或不支持内容缓冲指示；QoE上报指示为上报QoE指示或不上报QoE指示；网络信息上报指示为上报网络信息指示或不上报网络信息指示网络信息包括UE标识、服务小区标识和网络拥塞状态中的至少一个；广告消费信息指示为上报用户消费广告内容事件指示或不上报用户消费广告内容事件指示；广告插入能力指示为支持广告插入指示或不支持广告插入指示。
104、SCEF将从BM-SC获取的开放的第一MBMS能力信息发送给第三方服务器，使第三方服务器根据开放的第一MBMS能力信息请求启动MBMS广播并向用户设备UE分发视频内容。
在SCEF将从BM-SC获取的第一MBMS能力信息发送给第三方 服务器之前，方法还包括：SCEF接收BM-SC发送的第三响应消息，第三响应消息包括第一MBMS能力信息、传送视频内容的业务入口链接、BM-SC的端口信息、BM-SC提供的计费规则以及BM-SC的媒体编码信息。
其中，传送视频内容的业务入口链接可以为BM-SC提供的用户业务描述(User Service Description，USD)统一资源定位符((Uniform Resoure Locator，URL)，或者BM-SC的域名地址等。BM-SC的端口信息用于BM-SC与第三方服务器之间的信任通道数据传输。
SCEF再将从BM-SC获取的第一MBMB能力信息、传送视频内容的业务入口链接、BM-SC的端口信息、计费规则以及BM-SC的媒体编码信息发送给第三方服务器，这样，第三方服务器就会向3GPP网络请求启动MBMS广播，将视频内容根据BM-SC开放的MBMS能力信息通报给UE，即将UE的请求重定向至MBMS广播接收模式接收视频内容，以将MBMS能力扩展到OTT视频支持，简化了OTT第三方提供视频服务的技术难度，OTT第三方不需要和不同的运营商、不同的终端类型单独进行协商并测试，降低了OTT第三方的工作量。
本发明实施例提供一种视频分发方法，SCEF接收第三方服务器发送的第一请求消息，第一请求消息包括第三方服务器请求用于视频分发的多媒体广播多播服务MBMS能力协商参数，根据第一请求消息向归属地签约用户服务器HSS发送第二请求消息，以向HSS请求开放MBMS能力，SCEF在接收到HSS确定允许MBMS能力开放时返回的第二响应消息时，向多媒体广播服务中心BM-SC发送第三请求消息，以请求获取BM-SC开放的第一MBMS能力信息，SCEF将从BM-SC获取的开放的第一MBMS能力信息发送给第三方服务器，使第三方服务器根据开放的第一MBMS能力信息启动MBMS广播并向用户设备UE分发视频内容，也即，在多个UE访问视频内 容时，提供视频内容的第三方服务器可与3GPP的SCEF和BM-SC交互，根据MBMS能力协商参数与BM-SC协商确定开放的MBMS能力，第三方服务器就会将UE的请求重定向至广播接收模式接收视频内容，将MBMS能力扩展到OTT视频支持，OTT第三方不需要与不同的运营商和终端进行协商并测试，简化了OTT提供视频服务的技术难度，能够解决运营商将MBMS的媒体能力开放给OTT第三方工作量大、管理复杂以及OTT第三方通过移动网络分发视频时IOT工作量大、视频分发和管理负荷重的问题。
基于上述实施例，下面对本发明的实施例作以具体说明。
针对OTT视频服务器在检测到至少两个UE访问相同的视频内容后再向3GPP网络请求MBMS能力开放的场景，本发明又一实施例提供一种视频分发方法，如图2所示，包括：
201、第三方服务器检测到至少两个UE访问相同的视频内容。
示例性的，UE1向第三方服务器发送HTTP请求消息，请求发送视频内容，该HTTP请求消息包括该视频内容对应的URL，UE2也向第三方服务器发送HTTP请求消息，也向第三方服务器请求相同的URL对应的视频内容，第三方服务器便根据URL检测到多个UE访问相同的视频内容，第三方服务器便确定调用3GPP网络的视频能力来分发视频内容。
202、第三方服务器向SCEF发送第一分配TMGI请求，该分配TMGI请求包括第三方服务器请求用于视频分发的MBMS能力协商参数。
利用已有的分配TMGI请求(Allocate TMGI Request)，并通过标准开放的接口在该分配TMGI请求中增加用于视频分发的MBMS能力协商参数。即这里的第一分配TMGI请求就相当于上述实施例中的第一请求消息，该第一分配TMGI请求包括第三方服务器请求用于视频分发的MBMS能力协商参数。该MBMS能力协商参数可以包括：视频内容的传输模式指示(transport mode indication)，该传 输模式指示可包括广播模式(Broad Cast only)、或广播/单播混合模式(hybrid Broad Cast/Unitary Cast，hybrid BC/UC)、或动态广播/单播模式(dynamic BC/UC)，即在广播模式和单播模式动态切换的模式；还可包括使用MBMS的安全特性(MBMS security feature allowed)指示，该安全特性指示为打开状态或关闭状态；还可包括内容转码能力支持指示(content transcoding capability support)，包括支持转码指示或不支持转码指示；还可以包括内容缓冲指示(caching support)，包括支持内容缓冲指示或不支持内容缓冲指示；还可以包括广告插入能力指示，该广告插入能力指示为支持广告插入或不支持广告插入；还可以包括体验质量(Quality of Experience，QoE，QoE)上报指示，QoE上报指示为上报QoE指示或不上报QoE指示；还可以包括网络信息上报指示，网络信息上报指示为上报网络信息指示或不上报网络信息指示，网络信息包括UE标识、服务小区标识和网络拥塞状态中的至少一个；还可以包括广告消费信息指示，广告插入能力指示为支持广告插入指示或不支持广告插入指示。
该第一分配TMGI请求还可以包括第三方服务器的端口信息(SCS port infomation)，例如SCS的IP地址和端口号，用于第三方服务器与BM-SC之间的信任通道数据传输；还可以包括第三服务器的媒体编码信息(media layer infomation)，例如包括视频编码信息，譬如视频H.264/H.265等；和音频编码信息，譬如自适应多速率宽带编码(Adaptive Multi-rate-Wideband，AMR-WB)，自适应多速率窄频带编码(Adaptive Multi-rate Narrowband，AMR-NB)，增强语音服务(Enhanced Voice Service，EVS)等。还可以包括其它的媒体信息，例如文本编码信息、图片编码信息等。
当然，该第一分配TMGI请求还包括该请求中已有的视频内容的组的标识(external group ID)、SCS ID和UE IDs等。
203、SCEF向HSS发送签约信息请求，以向HSS请求开放MBMS 能力。
SCEF在接收到第一分配TMGI请求时，便向HSS发送签约信息请求(subscriber infomation request)，相当于上述实施例中的第二请求消息，该签约信息请求中可以携带上述MBMS能力协商参数和/或MBMS媒体能力开放请求指示，MBMS媒体能力开放请求指示用于请求HSS开放MBMS管道能力，还可以包括external group ID和SCS ID等，以向HSS请求开放MBMS能力给OTT第三方，例如搜狐视频、乐视电视等。
204、HSS检查签约信息，确定是否允许MBMS能力开放给OTT第三方，并向SCEF发送签约信息响应。
根据步骤203的说明，签约信息请求可以包括MBMS能力协商参数，或者MBMS媒体能力开放请求指示，或者MBMS能力协商参数和MBMS媒体能力开放请求指示，或者签约信息请求不做参数或指示的增加。
当签约信息请求不做参数或指示的增加时，若HSS接收到签约信息请求时，该签约信息请求也可根据external group ID和SCS ID等于与运营商的签约信息确定是否开放MBMS能力给第三方，如果确定是，则向SCEF发送表征允许开放MBMS能力的签约信息响应(subscriber infomation response)，也相当于上述实施例中的第二响应消息；
如果签约信息请求包括MBMS媒体能力开放请求指示且未包括MBMS能力协商参数，则可以理解为MBMS管道能力包括MBMS媒体能力，当HSS确定允许开放MBMS管道能力时，由于未携带MBMS能力协商参数，则不做具体的能力判定开放哪些媒体能力就向SCEF返回包括MBMS能力开放请求指示的签约信息响应，以便SCEF进一步向BM-SC请求开放的MBMS媒体能力信息；
如果签约信息请求未包括MBMS媒体能力开放请求指示，而是包括MBMS能力协商参数，则可以理解为MBMS管道能力是体现在 MBMS能力协商参数中的，如果HSS接收到签约信息请求，在与运营商的签约信息确定开放MBMS管道能力的情况下，进一步根据MBMS能力协商参数与签约信息确定开放哪些MBMS能力给第三方，并将确定的MBMS能力信息通过签约信息响应返回给SCEF；
如果签约信息请求既包括MBMS媒体能力开放请求指示，也包括MBMS能力协商参数，可以理解为MBMS管道能力与MBMS媒体能力并列，则HSS先根据签约信息确定是否开放MBMS管道能力，如果确定开放，则进一步根据MBMS能力协商参数与签约信息确定开放哪些MBMS能力，并向SCEF返回包括MBMS能力开放请求指示和确定开放的MBMS能力信息的签约信息响应，以便于SCEF进一步向BM-SC请求具体的MBMS能力信息。
其中MBMS管道代表了两节点之间传输数据的能力。
205、SCEF向BM-SC发送第二分配TMGI请求，第二分配TMGI请求用于向BM-SC获取开放的MBMS能力信息。
在SCEF确定HSS允许开放MBMS能力给OTT第三方时，SCEF便向BM-SC发送第二分配TMGI请求，相当于上述实施例中的第三请求消息，该第二分配TMGI请求中增加有MBMS能力协商参数或HSS确定开放的MBMS能力信息，还可增加上述SCS port infomation、媒体信息等。
也即，如果HSS不对开放给第三方的MBMS能力做具体判定，则SCEF将从第三方服务器获得的MBMS能力协商参数发送给BM-SC，以便BM-SC根据MBMS能力协商参数和与运营商的签约信息确定具体开放哪些MBMS能力；如果HSS根据SCEF发送的MBMS能力协商参做了能力判定，确定开放哪些MBMS给第三方，那么BM-SC则进一步根据与运营商的签约信息，根据从SCEF获得的HSS确定的MBMS能力信息中的MBMS能力的集合再进一步确定开放哪些MBMS能力给第三方。
206、BM-SC根据与运营商的签约信息确定开放的MBMS能力 信息，并将MBMS能力信息发送给SCEF。
BM-SC确定具体的开放的MBMS能力信息，即基于BM-SC的能力对开放特性进行仲裁，例如具体的MBMS能力信息包括动态单播/广播转换能力、媒体转码能力等，并将确定的具体的MBMS能力信息返回给SCEF，该具体的MBMS能力信息可以携带在第一分配TMGI响应消息(allocate TMGI response)中。
其中，BM-SC可同时提供BM-SC的端口信息(BM-SC port infomation)、BM-SC提供的计费规则、BM-SC的媒体编码信息以及BM-SC根据仲裁结果构建的传送视频内容的业务入口链接，例如USD URL，还包括分配的TMGI等。
207、SCEF将MBMS能力信息转发给第三方服务器。
SCEF可将从BM-SC接收到的MBMS能力信息、计费规则BM-SC的端口信息、传送视频内容的业务入口链接以及BM-SC的编码信息携带在第二分配TMGI响应消息中转发给第三方服务器SCS/AS。这时，就会触发第三方服务器就会将UE的请求重定向到广播接收模式接收视频内容。
针对以上说明，假设第三方服务器向SCEF请求10个能力(特性)，根据费率不同或运营商策略，BM-SC只提供其中的5个能力，然后将这5个能力通过SCEF返回给第三方服务器，第三方服务器就只能和UE/BM-SC之间使用这5个能力。
例如传输模式指示，传输模式有三个选项：广播模式、广播/单播混合模式和动态广播/单播模式。广播模式指BM-SC只提供广播能力，只有在MBMS覆盖区的UE可以接收媒体内容，则不在MBMS覆盖区的UE只能到OTT单播服务器获取媒体内容；广播/单播混合模式指3GPP网络提供单播/广播混合传输能力，当UE不在MBMS覆盖区时，UE可以到3GPP网络单播服务器获取媒体内容；动态广播/单播模式，UE仍然可以从3GPP网络获取媒体内容，但3GPP网络会选择最佳的传送方式将内容发送给UE。该种方法与混合单播/ 广播模式的差别在于：混合单播/广播方式的MBMS覆盖区是半静态的，当MBMS覆盖区选定后，即使接收用户的数量少，依然是广播方式，即使在MBMS覆盖区外的用户数很多，依然只能通过单播方式获取媒体内容。动态单播/广播则可以根据区域内用户数的密度情况，动态选择广播或者单播方式，从而可以实现网络传输容量的最佳使用。当OTT第三方通过标准开放的接口询问运营商网络(SCEF)查询BM-SC支持的视频能力并协商传输模式时，广播模式only下，OTT仍然需要配置单播服务器；混合单播/广播模式不要求OTT配置单播服务器，但3GPP网络的容量利用效率不高；动态单播/广播实现3GPP网络容量的最大化使用。三种不同的传输模式可以对应不同的费率。
再比如内容缓存能力，如果OTT第三方不通过标准开放的接口询问运营商网络(SCEF)查询BM-SC支持的视频能力，假设BM-SC不支持内容缓存能力，则UE后续的单播请求仍然由OTT第三方提供，OTT第三方需要配置大量的单播服务器，需要的服务器容量大，反之，如果OTT第三方与3GPP网络的SCEF进行交互请求调用3GPP网络BM-SC的MBMS视频支持能力，且BM-SC支持内容缓冲能力，则UE后续的单播请求由3GPP网络单播服务器提供，3GPP网络单播服务器可以从BM-SC获取已缓冲的内容，或者BM-SC本身就提供3GPP网络单播服务器支持，此时，OTT第三方无需再关注服务器容量的问题。
可以理解的是，上述MBMS能力协商参数和MBMS能力信息也可以通过单独的消息进行发送。
根据上述开放的MBMS能力信息，启动MBMS广播分发视频内容的过程可以如下：
208、第三方服务器将传送视频内容的业务入口链接通过和UE之间的HTTP交互知会给UE。
209、第三方服务器向SCEF请求启动MBMS广播。
第三方服务器具体可以向SCEF发送请求消息group message request，其中可包括上述exernal group ID、SCS ID等。
210、SCEF根据前述上下文对第三方服务器发送的请求进行授权检查。
211、若授权检查确定启动MBMS广播，则SCEF向HSS查询该第三方服务器是否可以利用MBMS通道。
具体SCEF可向HSS发送subscriber information request，其中包括上述exernal group ID、SCS ID等，以使得HSS根据签约信息确定第三方服务器是否可利用MBMS通道。
212、若HSS确定是，则HSS向SCEF发送确定响应(subscriber information response)。
213、SCEF启动MBMS广播。
214、SCEF向第三方服务器发送启动MBMS确认消息。
如果上述步骤208不执行，则在步骤214之后可执行步骤215，即知会给UE传送视频内容的业务入口链接可以是第三方服务器执行，也可以是SCEF执行，步骤208与步骤215可任选一个。
215、SCEF与UE进行通信，知会UE传送视频内容的业务入口链接，UE侧的MBMS客户端就绪，第三方服务器将视频内容发送给BM-SC/SCEF。
可选的，在步骤206中，也可以携不需要携带BM-SC构建的USD URL，而携带BM-SC的域名地址，这样再经过SCEF或者AS告诉给UE后，UE可根据对域名地址进行解析，可得知从BM-SC获取USD URL。即传送视频内容的业务入口链接也可以为BM-SC的域名地址。
216、SCEF向BM-SC发送激活承载请求消息(activate MBMS bearer request)。
217、BM-SC建立MBMS承载。
218、BM-SC向SCEF发送MBMS承载建立成功消息(activate MBMS bearer response)。
219、BM-SC启动广播并将从第三方服务器获取的内容发送至广播承载上。
220、第三方服务器持续地向BM-SC/SCEF推送视频内容。
221、UE通过MBMS承载获取视频内容。
UE根据获取的BM-SC提供的视频内容的业务入口链接USD URL，通过MBMS承载获取视频内容。
可以理解的是，如果第三方服务器向SCEF发送的MBMS能力协商参数中还携带上报QoE指示、上报网络信息指示和上报广告消费信息指示中的至少一个，则在第三方服务器通过BM-SC或者SCEF向UE分发视频内容之后，BM-SC还需要向第三方服务器上报QoE、网络信息和广告消费信息中的至少一个，或者UE通过SCEF向第三方服务器上报，本申请不做限定。
需要说明的是，如果BM-SC返回的媒体编码信息和第三方服务器请求的媒体编码信息不同，第三方服务器需要将视频内容按照BM-SC提供的媒体编码信息进行转码；当然，如果BM-SC提供内容转码服务，第三方服务器可以直接将视频内容发送给BM-SC，由BM-SC将媒体格式转码成UE支持的内容格式，然后由BM-SC将内容发送给UE。
本实施例中各网元之间的交互可参见图3。
因此，本发明实施例是在UE先访问第三方服务器时，第三方服务器如果检测到多个UE访问相同的视频内容后，和3GPP网络的SCEF进行交互，请求调用3GPP网络的MBMS视频支持能力，3GPP网络许可MBMS视频支持能力启动，第三方服务器便将UE的请求重定向至广播接收模式接收视频内容，通过本发明，可将MBMS能 力扩展到OTT视频支持，OTT第三方不需要与不同的运营商和终端进行协商并测试，简化了OTT提供视频服务的技术难度，相当于OTT第三方将视频传输的工作外包给运营商网络，通过公开的端口和MBMS能力协商参数，OTT第三方不需要和不同的运营商针对不同的管道、终端的视频支持能力等参数和运营商单独进行协商并测试，能够解决运营商将MBMS的媒体能力开放给OTT第三方工作量大、管理复杂以及OTT第三方通过移动网络分发视频时IOT工作量大、视频分发和管理负荷重的问题。
针对第三方服务器预先向3GPP网络请求MBMS能力开放的情况，本发明又一实施例提供一种视频分发方法，如图4所示，包括：
401、第三方服务器向SCEF发送第一分配TMGI请求，该分配TMGI请求包括第三方服务器请求用于视频分发的MBMS能力协商参数。
402、SCEF向HSS发送签约信息请求，以向HSS请求开放MBMS能力。
403、HSS检查签约信息，确定是否允许MBMS能力开放给OTT第三方，并向SCEF发送签约信息响应。
404、SCEF向BM-SC发送第二分配TMGI请求，该第二分配TMGI请求用于向BM-SC获取开放的MBMS能力信息。
405、BM-SC根据与运营商的签约信息确定开放的MBMS能力信息，并将MBMS能力信息发送给SCEF。
406、SCEF将MBMS能力信息转发给第三方服务器。
其中，步骤401～步骤406的具体实现方式可参见上述实施例中的步骤202～步骤207。
407、第三方服务器向SCEF请求启动MBMS广播。
第三方服务器具体可以向SCEF发送请求消息group message request，其中可包括上述exernal group ID、SCS ID、SCS的端口信 息等。
408、SCEF根据前述上下文对第三方服务器发送的请求进行授权检查。
409、若授权检查确定启动MBMS广播，则SCEF向HSS查询该第三方服务器是否可以利用MBMS通道。
