在本实施例中, 应用功能实体 (推送业务触发单元) 和接收功能实体 (推送业务接收单元) 在 UE上实现, 业务控制功能实体即业务控制单元在 SCF实体上实现。 用户通过 UE浏览节目导航信息等确定待切换的节目信 息, UE按照推送业务信息格式生成定时频道切换定制请求, 即推送业务请 求, 包括待推送的用户标识、 频道标识及切换时间信息; SCF实体接收用户 通过 UE发起的定时频道切换定制请求, 并根据定制请求中包含的用户信 息、 节目信息及时间信息在条件满足时触发推送业务逻辑, 向指定用户发起 频道切换请求。
该方法包括: 501 , UE通过 SIP消息 (SIP MESSAGE) 发起频道切换定制请求, 其 中:
Request-URI为 SCF的 PSI标识;
SIP MESSAGE消息体中包含频道切换信息, 这里 UE基于推送业务信 息模板生成频道切换信息, 包含推送业务信息, 推送业务信息中包含推送业 务标识。
MESSAGE sip: bc-scf. iptv.com SIP/2.0
To: <sip:bc-scf.iptv.com>
Content-Type: application/xml
Content-Length: 127
<?xml version:" 1.0" encoding="UTF-8"?>
<IPTVActionDataCommand

<SessionPush>
<push:IPTVPushActionData>
<UserList>sip:user-a@iptv.com</UserList>
<PushContentId>Channel- 1 </PushContentId>
<StartTime>21 :00:00</StartTime>
</push:IPTVPushActionData>
</SessionPush>
</IPTVActionDataCommand>
502, 核心 IMS ( Core IMS ) 向 SCF实体转发 SIP MESSAGE;
503 , SCF实体接收并解析 SIP MESSAGE, 该过程包括:
检测并解析消息体, 根据 xml中包含 "IPTVActionDataCommand"元素, 并且值域为" SessionPush"确定为触发推送业务逻辑; 检测并解析消息体, 从 xml中' 'IPTVPushActionData"元素的值域获取推 送业务信息;
SCF实体可以根据推送业务信息中的用户标识 (UserList) 、 内容标识 (PushContentld) 确定用户是否有收看该节目的权限;
本实施例中 SCF实体确定在 21 :00时向用户 sip:user-a@iptv.com发起
Channel- 1的推送请求。
504, SCF实体确定用户可以完成定时切换, 向 UE发送成功响应消息 (200OK消息) ;
505 , Core IMS向 UE转发成功响应消息;
506, SCF实体根据获取的推送业务信息及媒体参数信息发起推送业务 请求, 本实施例中为 SIP INVITE, 其中:
Request-URI为从推送业务信息中获取的用户标识 (UserList) ;
From 头域携带从推送业务描述信息中获取待切换的频道标识 (PushContentld) , 这里为 SIP标识, 其中 user part部分携带频道标识, 域 名部分为 SCF的域名;
P-Preferred-Service 头 域 中 可 以 携 带 推 送 业 务 标 识 urn:xxx:iptv.sessionpush, 用于向用户终端指示当前发起的为推送业务请求;
Content-Type包含 application/sdp类型, 通过 SDP offer发起媒体协商, 携带待推送频道的媒体参数信息;
INVITE sip: user-a@iptv.com SIP/2.0
From: <sip: Channel- 1 @cod-scf.iptv.com>;tag=31417
To: <sip:user-a@iptv.com>
P-Preferred- Service: urn:xxx:iptv.sessionpush 待推送频道的媒体参数信息包括组播地址、 媒体格式、 带宽等一种或者 多种信息。 这里 SCF实体可以通过多种方式获取媒体参数信息, 包括: SCF实体上预先配置保存相关的信息;
SCF实体根据频道标识通过 SIP或非 SIP请求从保存有媒体参数信息的 功能实体获取媒体参数信息。
507, Core IMS向 UE转发推送业务请求;
508, UE解析收到的推送业务请求, 获取待推送的频道信息及媒体参 数信息, 并通过发送 200 OK消息做出响应。 这里 UE可以基于推送业务标 识、 频道信息等通过 UE本地应用向用户呈现相关信息, 为用户提供选择, 例如是否切换到该频道, 用户可以通过遥控器做出选择, UE基于用户的选 择做出响应, 当用户选择同意切换时 UE再发起成功响应;
509, Core IMS向 SCF实体转发 200OK消息;
510, SCF实体接收到 UE发送的 200OK消息, 完成会话建立;
511, UE接收媒体流, UE根据会话协商中获取的多播地址加入多播组 接收媒体流, 完成频道切换。
本实施例提供的业务推送方法中, 业务控制功能实体对外提供标准接 口, 通过推送业务信息触发推送业务逻辑, 完成推送业务。 本发明实施例提 供了一种频道定制切换业务的推送方法, 各应用功能本身只需要完成相应的 应用逻辑管理即可, 不需要重复实现会话协商及媒体协商等功能, 可以有效 地提高新应用功能的部署效率, 简化网络的复杂度。
如图 6所示, 图 6为本发明的业务推送协商方法的具体实施例二的示意 图。
本实施例中的应用功能实体 (推送业务触发单元) 在广告功能 (Advertise Function, ADF ) 实体上实现, 接收功能实体 (推送业务接收单 元) 在 UE上实现, 业务控制功能实体 (业务控制单元) 在 SCF实体上实 现。 这里的 ADF实体可以是后台配置功能实体, 也可以是一个应用功能实 体; 本实施例中广告媒体由媒体功能 (Media Function, MF ) 提供, 实际部 署中也可能是由其它功能实体提供, 例如直接由 ADF实体提供广告媒体, 也可能是由其它实体提供给 MF, 再由 MF转发给 UE; 这些情况与具体的 广告业务相关。
该方法包括:
601, BC节目中的广告时间到达, 广告服务器触发业务逻辑, 通过单 播方式向用户提供个性化广告, 广告服务器根据推送业务信息模板生成推送 广告信息, 其中包括待推送的用户信息, 待推送的广告信息等; 广告服务器 通过 SIP MESSAGE向 SCF实体发送推送业务信息, 其中:
Request-URI为 SCF实体的 SIP标识, 用于将 SIP消息路由到 SCF, 可 以是 PSI;
P-Preferred-Service头域中包含推送业务标签;
SIP MESSAGE消息体中包含待推送业务信息;
另外, 如果 ADF实体提供广告的媒体参数, MESSAGE消息体中也可 以携带广告的媒体参数信息, 媒体参数通常通过 SDP携带;
SIP 消息中携带多种类型的消息体, 考虑 Content-Type 使用 multipart/mixed类型, 可通过 SDP和 XML共同对推送业务信息进行定义。
MESSAGE sip: cod-scf.iptv.com SIP/2.0
From: <sip:adf.iptv.com>;tag=31415

602, SCF实体接收并解析 SIP MESSAGE, 并向 ADF实体发送成功响 应消息, 包括:
检 测 SIP 消 息 头 域 中 包 含 "P-Preferred-Service: urn:xxx:iptv.sessionpush" , 确认为推送业务消息;
检测并解析消息体, 根据 application/iptvsad-sessionpush消息类型获取 推送业务信息, 包括推送内容标识 ( PushContentld ) , 待推送用户信息 (UserList) , 推送时间信息 ( StartTime, Duration) ; 检测并解析消息体, 如果包含 application/sdp, 则获取推送内容的媒体 参数信息。
603 , SCF 实 体 根 据 推 送 业 务 标 识 ( P-Preferred-Service: urn:xxx:iptv.sessionpush ) 触发推送业务逻辑, 发起推送业务请求, 这里为 SIP INVITE:
从推送业务描述信息中获取用户标识, 作为 Request-URI发起会话请 求;
从推送业务描述信息中获取待推送的广告标识, 作为 user part部分, 与 SCF实体的域名共同组成 SIP标识, 并通过 From头域携带;
推送业务请求中还可以通过 P-Preferred-Service头域携带推送业务标 识, 向 UE指示该请求为推送业务请求;
SCF实体还可以通过 SIP INVITE消息体携带广告内容的媒体信息, 本 实施例中媒体参数信息由 ADF实体在发起推送业务请求时通过 SDP携带;
INVITE sip: user-a@iptv.com SIP/2.0
From: <sip:Ad-l@cod-scf.iptv.com>;tag=31417
To: <sip:user-a@iptv.com>

a=rtpmap:99 h263- 1998/90000
604, Core IMS向 UE转发 SIP请求消息;
605, UE接收并解析 SIP请求消息;
如果 SIP请求消息通过 P-Preferred-Service头域携带了推送业务标识,
UE可以基于该标识触发推送业务逻辑完成推送业务相关的处理;
UE解析 From头域携带的 SIP标识, 从 user part获取推送广告标识, 这 里为 Ad-1 ;
如果 SIP请求消息通过消息体携带 Ad-1的 SDP媒体参数信息, 需要从 SDP获取这些信息;
UE检测确定 SCF实体没有发起 SDP offer, 因此通过响应消息发起 SDP offer进行媒体参数协商; 这里可以通过 200 OK响应发起 SDP offer;
606, Core IMS向 SCF实体转发 200OK响应消息;
