否则执行步骤 405： 本步骤具体由资讯服务器的控制模块完成，即控制模块收到注册请求信 令时判断发送注册请求信令的终端是否已开通资讯插播服务； 步一骤 404: 资 ifU艮务器记录所述终端的注册信息， 并返回注册资 ifU艮务 器成功信令给信令服务器， 执行步骤 306; 本步骤也由资讯服务器的控制模块完成，即控制模块将所述终端的注册 信息写入资讯服务器的订阅信息模块， 然后返回注册资讯服务器成功信令给 所述信令服务器； 步骤 405 : 返回注册资讯服务器失败信令给信令服务器； 本步骤由资讯服务器的控制模块完成，即控制模块返回注册资讯服务器 失败信令给信令服务器； 本实施例中， 对于终端 A, 资讯服务器首先将其注册信息写入订阅信息 模块， 并返回 200 OK消息给信令艮务器表示 A开通了资讯插播艮务； 对于 终端 B, 资讯服务器仅返回步骤 404中的消息给信令服务器表示 B并未开通 资讯插播服务； 步骤 406: 信令服务器收到资讯服务器返回的信令后返回注册成功信令 给终端； 即， 无论 A、 B是否开通了资讯插播服务， 信令服务器都会给予注册并 返回注册成功信令， 此时 A、 B间建立会话； 步骤 407: 资讯服务器定时向已注册的终端发送资讯播放请求信令， 请 求插播资讯； 本实施例中， 资讯服务器的控制模块轮询订阅信息模块中储存的信息, 定时向终端 A发送资讯播放请求信令； 其它实施例中， 若视频共享的双方终 端都开通了资讯插播服务， 则资讯服务器可以定时或者随时发送资讯播放请 求信令给双方终端； 步骤 408： 终端收到资讯播放请求信令后， 判断自身是否正在进行视频 共享， 若是， 则执行步骤 309; 否则， 执行步骤 312; 步骤 409: 终端与所述资讯服务器进行媒体协商， 若成功， 则执行步骤 310; 否则， 本次资讯插播结束； 步骤 410: 终端通过信令艮务器发送暂停视频共享信令给视频共享的对 方终端， 并等待对方终端的响应信令； 即终端 A 同意插播资讯后， 发送暂停视频共享信令给信令服务器， 信 令服务器将所述信令转发给终端 B; 步骤 411 : 终端判断是否在设定时间内收到对方终端的响应信令，若是， 则执行步 4聚 413; 否则， 执行步 4聚 412; 步 4聚 412: 发送拒绝请求信令给所述资 ifU艮务器， 本次资讯插播结束； 步骤 413 : 终端发送接受请求信令给资讯艮务器； 步骤 414: 资讯服务器建立与终端之间的资讯媒体传输链路， 并在建立 成功后将要播放的资讯数据传输给终端； 当资讯服务器和终端媒体协商成功建立了资讯媒体传输链路之后，资讯 服务器的控制模块通知资讯服务器的资讯资源模块， 由资讯资源模块负责和 终端 A进行资讯传输； 步骤 415 : 终端播放接收到的资讯； 步骤 416: 资讯数据传输完毕， 资讯服务器发送结束资讯播放信令给终 端； 即， 资讯服务器的控制模块发送结束资讯播放信令给终端 A; 步骤 417: 终端收到后所述结束资讯播放信令后， 通过信令服务器发送 恢复视频共享信令给所述对方终端， 恢复被暂停的视频共享； 即， 终端 A 收到结束资讯播放信令后， 发送恢复视频共享信令给信令 服务器，信令服务器转发所述信令给终端 B,终端 A与终端 B恢复视频共享。 本发明中， 若 A 、 B任意一方在资讯插播过程中结束了被暂停的视屏 共享， 则需要经信令艮务器发送结束视频共享的信令给对方终端， 对方终端 收到后会发送终止资讯播放信令给资讯服务器要求终止资讯插播； 除此之外 终端不会发送结束资讯插播的请求给资讯服务器。 结合图 2 , 终端的内部工作流程如下： 终端的信令控制模块接收到资讯服务器发送的资讯播放请求时，首先判 断自身是否正在进行视频共享， 若没有进行视频共享， 则发送拒绝请求信令 给资讯艮务器， 拒绝资讯插播； 若正在进行视频共享， 则与资讯艮务器进行 媒体协商， 协商成功后， 发送暂停视频共享信令给视频共享的对方终端， 并 在收到对方终端的响应信令后通知媒体传输模块暂停视频共享数据的传输； 然后发送接受请求信令给资讯服务器， 通知资讯服务器开始传输将要插播的 资讯数据， 同时通知媒体传输模块接收资讯数据及通知媒体播放模块播放媒 体传输模块接收到的资讯数据；媒体传输模块接收资讯服务器发送来的数据， 媒体播放模块播放媒体传输模块接收到的资讯数据， 至此， 资讯插播正式开 始。 在资讯插播的过程中， 若信令控制模块接收到资讯服务器发送来的结束 资讯播放信令， 则发送恢复视频共享信令给对方终端， 收到对方终端的响应 信令后通知媒体传输模块恢复视频共享数据的传输； 若信令控制模块接收到 对方终端经信令艮务器发送来的终止视频共享信令， 则发送终止资讯播放信 令给资讯服务器要求终止资讯插播。 以上针对较佳实施例的描述较为详细，但不能因此而认为是对本发明的 限制， 凡与本发明所揭示的原理类似的实施， 均在本发明的保护范围内， 本 发明的保护范围应以所附权利要求为准。
