图 2为本发明多媒体会议的实现系统的结构示意图。 具体实施方式
本发明提出 BS模式的多媒体会议， 其基本思想是： 用户登录 Web页面 或客户端， 通过会议 Web服务器（Conf WS )和会议业务能力服务器（ Conf AS )将创建会场的请求发送给媒体资源服务器（MRS ) ； MRS创建会场成 功后，用户通过 Web页面或客户端添加会议成员，并通过 Conf WS和 Conf AS 邀请会议成员； 会议成员在 Conf AS上召开会议。
BS模式的多媒体会议， 指用户通过 Web浏览器或者客户端进行会议的 召开和会议的控制操作。
在本发明的具体实施例中，会议 Web服务器（ Conf WS, Conference Web Server )和会议业务能力月良务器 ( Conf AS, Conference Application Server ) 互通所用的传输控制协议 ( TCP, Transmission Control Protocol ) 消息是本 发明自定义的， 格式如表 1所示：

表 6
Conf WS保存 Conf AS发送的会议成员的状态信息； 如果还想继续邀 请会议成员， 用户通过 Web页面或客户端弹出的会议控制界面再添加会议 成员， 填写完毕后将邀请会议成员的 HTTP Post请求发送给 Conf WS, 后 面的步骤与前面的描述一样， 这里不再重复。
步骤 103 , 会议成员在 Conf AS上召开会议；
具体的， 在邀请会议成员成功后， 会议成员在 Conf AS上召开会议， MRS为各个会议成员所在终端分配会议资源， 使各个会议成员所在终端与 所分配的会议资源对应连接， MRS命令会议芯片混音， 会议芯片把来自各 个会议成员所在终端的语音流进行混音处理， 这样就能使得各个会议成员 可以听到彼此的声音； 在会议召开时， Conf WS如果收到 Web页面或客户 端发送的更新会议信息的 HTTP Get请求， 就向 Web或客户端返回 HTTP 响应， 响应中携带会议和会议成员的最新状态， 收到响应后， Web 页面或 客户端显示成员具体的状态信息， 该信息包括会议成员是否在线， 会议成 员的号码等。 步骤 104, 用户登录 Web页面或客户端结束会议；
具体的， 用户登录 Web页面或客户端点击结束会议， 并发送结束会议 的 HTTP Post请求给 Conf WS , Conf WS将结束会议的 TCP请求消息发送 给 Conf AS , 该 TCP消息中 Functionld为 101 , 消息中携带的具体内容如表 7所示：

表 7
Conf AS向被邀请的会议成员的终端和 MRS发送 BYE, 进行呼叫和资 源的释放， 所有呼叫和媒体资源释放完毕后， Conf AS向 Conf WS返回会 议结束的 TCP响应消息， 该消息中 Functionld为 101 , 消息中携带的具体 内容如表 8所示：
Figure imgf000013_0002
表 8
Conf WS向 Web页面或客户端返回会议结束的 HTTP响应， Web页面 或客户端提示会议已结束。
为实现上述方法， 本发明还提供了一种多媒体会议的实现系统， 图 2 是本发明多媒体会议的实现系统的结构示意图， 如图 2所示， 该系统包括： 登录模块 21、 Conf WS 22、 Conf AS 23、 MRS 24; 其中，
