一般情况下， 一个企业只会部署一套会议系统， 则对于用户来讲， 会议接 入号总是保持不变的， 每次参加会议时只需要关注会议号码即可。 但是， 由于 现在的大中型企业可能会同时部署多套会议系统， 比如一个企业同时部署了三 套会议系统， 分別是语音会议系统、 视频会议系统和桌面会议系统。 那么， 每 个会议系统会具有不同的会议接入号， 每个会议系统中的每个会议都具有不同 的会议号码。 此时， 用户需要参加一次会议时， 需要同时关注会议接入号和会 议号码， 如果用户先后需要参加很多次会议， 那么会议接入过程需要多次输入 不同的会议接入号和会议号码的组合， 将会非常繁瑣。 发明内容

为使本发明的目的、 技术方案和优点更加清楚， 下面将结合附图对本发明 实施方式作进一步地详细描述。
请参考图 1，其示出了本发明实施例所涉及的一种实施环境的结构示意图。 该实施环境包括终端 101、 呼叫控制网络 102、 会议接入装置 103和至少两套 会议系统 104。
终端 101可以是支持 SIP (Session Initiation Protocol, 会话发起协议） 的软 终端或者实体终端， 比如终端 101可以是运行于台式电脑上的支持 SIP的会议 应用程序， 或者支持 SIP的视频电话机等等。
呼叫控制网络 102通常是指能够根据被叫接入号进行路由的核心设备网， 比如 IMS (IP Multimedia Subsystem, IP多媒体系统）， NGN (Next Generation Network, 下一代网络） 网络。 呼叫控制网络 102可以接收终端 101 的呼叫请 求， 然后将呼叫请求根据会议接入号路由至对应的会议系统。
会议接入装置 103可以是一台电脑、 服务器或者设备， 为本发明实施例中 所新增的设备。会议接入装置 103分別与呼叫控制网络 102和各套会议系统 104 相连。 会议接入装置 103 也可以称之为 UCAG (Unified Conference Access Gateway, 会议统一接入号设备）。 会议接入装置 103用于接收终端 101根据统 一接入号发送的呼叫请求，然后指示终端 101和对应的会议系统 104建立会话， 并由会议系统 104根据会议号码将终端 101接入对应的具体会议中。
至少两套会议系统 104与会议接入装置 103相连， 至少两套会议系统 104 可以是两套或者两套以上， 各套会议系统 104的类型可以相同或者不同， 比如 至少两套会议系统 104具体为四套会议系统， 其中一套为语音会议系统， 另一 套为桌面会议系统， 其它两套为视频会议系统。 请参考图 2， 其示出了本发明一个实施例提供的会议接入方法的方法流程 图。 本实施例以该会议接入方法应用于图 1所示的会议接入装置 103来举例说 明， 该会议接入方法包括：
步驟 201， 会议接入装置接收终端发送的呼叫请求， 该呼叫请求携带终端 的媒体信息和与会议接入装置对应的统一接入号；
在本实施例中， 用户在接入会议时， 只使用一个接入号即可， 该接入号为 会议接入装置的接入号， 在本文中将会议接入装置的接入号称之为统一接入 号， 下文不再赘述。 具体地讲， 当需要接入会议时， 终端可以根据统一接入号 向会议接入装置发送呼叫请求， 该呼叫请求还携带有终端的媒体信息。 呼叫控 制网络可以根据统一接入号将该呼叫请求路由送达至会议接入装置。 此时， 会 议接入装置接收到终端发送的呼叫请求。具体地讲，终端的呼叫请求可以是 SIP 协议中的 INVITE (邀请） 信息。
步驟 202， 向终端发送携带会议接入装置的媒体信息的呼叫响应， 以建立 与终端的第一会话；
会议接入装置接收到终端发送的呼叫请求之后， 可以得到终端的媒体信 息。 此时， 会议接入装置向终端发送携带自身的媒体信息的呼叫响应， 与终端 进行媒体通道的协商， 来与终端之间建立第一会话。 该呼叫响应可以是 SIP协 议中的 200 OK消息。
步驟 203， 利用第一会话发送用于提示输入会议号码的信息；
在会议接入装置与终端建立第一会话之后， 会议接入装置利用第一会话向 终端发送提示输入会议号码的信息。 该过程可以使用 IVR (Interactive Voice Response, 互动式语音应答） 来实现。
步驟 204， 接收终端发送的会议号码；
终端可以通过已经建立的第一会话或者 SIP协议中的 INFO消息来向会议 接入装置发送其要加入会议的会议号码。会议接入装置对应地接收终端发送的 会议号码；
步驟 205， 在至少两个会议接入号中查询与会议号码对应的会议接入号； 会议接入装置可以采用下述两种方式中的任意一种来实现本步驟： 第一， 根据会议号码和会议接入号之间的关联关系，在至少两个会议接 入号中查询与会议号码对应的会议接入号；
会议接入装置可以预先得到会议号码和会议接入号之间的对应关系。 比 如， 会议接入装置提供会议预约功能， 在会议预约过程中从各个会议系统接收 会议号码， 并且根据接收到的会议号码， 生成会议号码与会议接入号之间的对 应关系。 此后， 当会议接入装置接收到终端发送的会议号码之后， 可以根据在 会议预约过程中生成的会议号码和会议接入号之间的对应关系， 查询与会议号 码对应的会议接入号。
第二， 分析会议号码的格式特性， 根据格式特性与会议系统的会议接入号 之间的对应关系， 在至少两个会议接入号中查询与会议号码对应的会议接入
对应关系。 具体地讲， 会议接入装置可以预先获得会议接入号对应的会议系统 所分配的会议号码的格式特性； 然后， 会议接入装置生成格式特性与会议系统 的会议接入号之间的对应关系。 比如， 会议接入装置预先获得的格式特性为： 一套会议接入号为 60681的会议系统生成的所有会议号码均为 5位数字， 另一 套会议接入号为 60682的会议系统生成的所有会议号码均为 6位数字， 则会议 接入装置可以生成会议号码的格式特性为 5位数字与会议接入号 60681之间的 对应关系， 以及会议号码的格式特性为 6位数字与会议接入号 60682之间的对 应关系。 此后， 当会议接入装置接收到终端发送的会议号码之后， 可以分析会 议号码的格式特性， 然后根据预先生成的格式特性与会议接入号之间的对应关 系， 查询与会议号码对应的会议接入号。
步驟 206， 根据会议接入号和会议号码指示终端建立与会议接入号对应的 会议系统的第二会话， 以便终端利用第二会话参加会议。
会议接入装置可以根据查询到的会议接入号和接收到的会议号码指示终 端和特定会议系统建立第二会话， 该特定会议系统是与会议接入装置查询到的 会议接入号对应的会议系统， 以便终端利用第二会话参加会议。 具体地讲， 本 步驟可以由两种方式实现， 第一， 会议接入装置向终端发送呼叫转移请求， 该 呼叫转移请求的转移目标字段携带会议接入装置查询到的会议接入号和接收 到的会议号码， 以便终端根据该呼叫转移请求中携带的会议接入号， 向对应的 会议系统发送携带有会议号码的呼叫请求来与会议系统建立第二会话， 并由会 议系统根据会议号码将终端接入对应的会议中； 第二， 会议接入装置在本步驟 之前先根据会议系统的会议接入号向会议系统发送携带有会议号码和终端的 媒体信息的呼叫请求， 并接收会议系统反馈的媒体信息； 然后会议接入装置向 终端发送修改会话请求， 该修改会话请求中携带会议系统的媒体信息， 以便终 端将建立第一会话时接收的会议接入装置的媒体信息修改为会议系统的媒体 信息， 从而与会议系统建立第二会话， 并由会议系统根据会议号码将终端接入 对应的会议中。 其中， 终端、 会议接入装置和会议系统的媒体信息， 可以是符合 SDP (Session Description Protocol, 会话描述协议） 要求的媒体信息， 该媒体信息 包括 IP地址、 端口号、 媒体类型、 媒体格式和传输协议。
综上所述， 本实施例提供的会议接入方法， 接收终端发送的呼叫请求， 所 述呼叫请求携带统一接入号， 并利用与所述终端建立的第一会话发送用于提示 输入会议号码的信息并接收所述终端发送的会议号码； 查询与该会议号码所对 应的会议系统的会议接入号， 然后根据会议接入号和会议号码来指示终端与对 应的会议系统建立第二会话， 以便终端利用第二会话参加会议， 解决了现有技 术中用户参加不同的会议系统中的会议时， 需要输入不同的会议接入号的问 题， 达到了终端总是通过统一接入号和不同的会议号码就可以接入不同的会议 系统参加会议的效果。 在上一实施例的步驟 205中， 可以由会议接入装置根据预先存储的会议号 码和会议接入号之间的对应关系， 查询与会议号码对应的会议接入号。 而会议 接入装置可以预先在会议预约过程中存储会议号码和会议接入号之间的对应 关系。 为此， 请参考图 3， 其示出了本发明另一实施例提供的会议预约方法的 方法流程图。 本实施例以该会议预约方法应用于图 1所示的会议接入装置 103 来举例说明， 该会议预约方法包括：
步驟 301， 接收会议预约方发送的会议预约请求， 会议预约请求携带有会 议类型， 会议类型包括语音会议、 视频会议或者桌面会议；
会议接入装置可以接收会议预约方发送的会议预约请求， 该会议预约请求 携带有会议类型，会议类型可以是语音会议、视频会议或者桌面会议中的一种。 在本实施例中， 以会议预约方为终端来举例说明。 但是需要说明的是， 会议预 约方也可以是会议门户， 会议门户是指专用于预约会议的网站门户， 也即企业 在设置多套会议系统时， 通常会同时设置一个用于预约会议的网站， 称之为会 议门户。 统；
会议接入装置在接收到会议预约请求之后， 可以根据会议预约请求中携带 的会议类型， 从至少两套会议系统中选择一套具有与会议类型相匹配的会议能 力的会议系统。 比如， 如果会议类型为视频会议， 则会议接入装置从至少两套 会议系统中选择具有视频会议能力的会议系统； 如果会议类型为桌面会议， 则 会议接入装置从至少两套会议系统中选择具有桌面会议能力的会议系统。
在具体的实施例中， 由于至少两套会议系统中可能存在两套或者两套以上 具有相同会议能力的会议系统， 比如， 至少两套会议系统中存在两套具有视频 会议能力的会议系统， 此时， 如果会议类型为视频会议， 则会议接入装置可以 选择出两套或者两套以上的具有匹配会议能力的会议系统。 为此， 若具有匹配 会议能力的会议系统包括两套或者两套以上， 会议接入装置可以根据预定策略 选择其中一套， 预定策略包括轮询策略、 负载均衡策略和随机策略中的任意一 种。
以具有视频会议能力的会议系统包括两套或者两套以上为例：
"轮询策略"是指： 此次会议预约请求携带的会议类型为视频会议时， 则会 议接入装置选择两套或者两套以上的具有视频会议能力的会议系统中的第一 套会议系统； 下次会议预约请求携带的会议类型为视频会议时， 则会议接入装 置选择两套或者两套以上的具有视频会议能力的会议系统中的第二套会议系 统； 再次会议预约请求携带的会议类型为视频会议时， 则会议接入装置选择两 套或者两套以上的具有视频会议能力的会议系统中的第三套会议系统， 依次类 推， 周而复始地顺序选择。
"负载均衡策略"是指： 会议接入装置可以向各套会议系统获取并保存对应 的负载信息， 然后此次会议预约请求携带的会议类型为视频会议时， 会议接入 装置选择两套或者两套以上的具有视频会议能力的会议系统中的负载最轻的 一套会议系统。
"随机策略"是指： 此次会议预约请求携带的会议类型为视频会议时， 会议 接入装置随机选择两套或者两套以上的具有匹配会议能力的会议系统中的一 套会议系统。
步驟 303， 向选择的会议系统发起会议预约；
会议接入装置选择出一套具有匹配会议能力的会议系统之后， 向选择的会 议系统发起会议预约， 使得会议系统预留相应的语音服务器的资源。
步驟 304， 接收会议系统反馈的对应的会议号码；
在会议系统成功预留资源之后， 会议系统会反馈会议号码给会议接入装 置。 此时， 会议接入装置可以接收到对应的会议号码。
需要补充说明的是， 为了避免两个不同的会议系统产生相同的会议号码， 各个会议系统可以采用不同的格式特性产生会议号码， 比如， 会议系统 1产生 的会议号码采用 1开头； 会议系统 2产生的会议号码采用 2开头。 当然， 也可 以由会议门户或者会议接入装置在预约过程中来统一生成会议号码。
步驟 305， 根据接收到的会议号码， 生成会议号码和会议接入号之间的对 应关系；
会议接入装置在接收到对应的会议号码之后， 生成该会议号码和会议接入 号之间的关联关系。比如，会议号码为 012345，会议系统的会议接入号为 60681， 则会议接入装置存储会议号码 "012345"与会议系统的会议接入号" 60681 "之间 的关联关系。 当然， 作为另一种存储形式， 会议接入装置也可以存储会议号码、 会议系统的名称和会议系统的会议接入号之间的关联关系。 比如， 会议号码为 012345, 会议系统的名称为华 X会议系统， 会议系统的会议接入号为 60681， 则会议接入装置存储会议号码 "012345"、 会议系统的名称"华 X会议系统"和会 议系统的会议接入号" 60681 "之间的对应关系。
步驟 306， 向会议预约方发送会议号码和统一接入号。
会议接入装置将指向自身的统一接入号和会议预约过程生成的会议号码 反馈给终端， 作为终端发送的会议预约请求的反馈。 比如， 会议接入装置将指 向自身的统一接入号" 60000"和会议号码 "012345"反馈给终端。
需要注意的是， 会议接入装置在此步驟中反馈的是指向自身的统一接入 号， 而不是会议系统的会议接入号。
另外， 如果会议预约请求是由会议门户发送的， 则此时会议接入装置将指 向自身的统一接入号和会议号码反馈给会议门户， 然后由会议门户通过邮件或 者短信之类的方式通知终端。
综上所述， 本实施例提供的会议预约方法， 通过在会议预约过程中存储会 议号码和会议系统的会议接入号之间的关联关系， 达到了可以使会议接入装置 总是能够在终端发起呼叫请求之前， 就预先存储关联关系的效果， 另外通过反 馈统一接入号而不是会议系统的会议接入号， 达到了使终端总是向统一接入号 来发起呼叫请求以启动会议接入过程的效果。
需要补充说明的是， 在优选地实施例中， 本实施例提供的会议预约方法可 以实现成为本发明实施例提供的会议接入方法中的一部分， 一方面， 实现了向 终端反馈统一接入号和会议号码， 也即实现向终端提供会议预约功能； 另一方 面， 也实现了预先存储会议号码和会议系统的会议接入号之间的关联关系的功 月匕。 由于本发明实施例提供的会议接入方法中， 会议接入装置指示终端与查询 到的会议接入号对应的会议系统建立第二会话存在两种实现方式， 为了对第一 种实现方式进行更为详细地描述， 请参考如下实施例：
请参考图 4， 其示出了本发明另一实施例提供的会议接入方法的方法流程 图。 本实施例以该会议接入方法应用于图 1所示的会议接入装置 103来举例说 明， 该会议接入方法可以包括图 3所示会议预约方法， 该会议接入方法包括： 步驟 401至 406， 可以参考步驟 301至步驟 306所示；
步驟 407， 会议接入装置接收终端发送的呼叫请求， 该呼叫请求携带终端 的媒体信息和与会议接入装置对应的统一接入号；
在本实施例中， 用户在接入会议时， 只使用统一接入号即可， 该统一接入 号为会议接入装置的接入号。 具体地讲， 当需要接入会议时， 终端可以根据统 一接入号向会议接入装置发送呼叫请求。呼叫控制网络可以根据统一接入号将 该呼叫请求路由送达至会议接入装置。 此时， 会议接入装置接收终端的呼叫请 求。具体地讲，该呼叫请求可以是 SIP协议中的 INVITE (邀请）消息，该 INVITE 消息携带有终端的媒体信息， 终端的媒体信息通常包括： 终端的 IP地址、 端 口号、 媒体类型、 媒体格式和传输协议。
步驟 408， 向终端发送携带会议接入装置的媒体信息的呼叫响应， 以建立 与终端的第一会话；
会议接入装置接收到终端发送的呼叫请求之后， 可以得到终端的媒体信 息。 此时， 会议接入装置向终端发送携带自身的媒体信息的呼叫响应， 与终端 进行媒体通道的协商， 来与终端之间建立第一会话。 该呼叫响应可以是 SIP协 议中的 200 OK消息， 该 200 OK消息携带有会议接入装置的媒体信息， 会议 接入装置的媒体消息通常包括： 会议接入装置的 IP地址、 端口号、 媒体类型、 媒体格式和传输协议。 也即， 终端和会议接入装置之间可以通过 INVITE消息 和 200 OK消息中携带的符合 SDP要求的媒体信息来进行媒体通道的协商，从 而建立用于发送提示输入会议号码的媒体通道 （也即第一会话）。
步驟 409， 利用第一会话发送用于提示输入会议号码的信息；
在会议接入装置与终端建立第一会话之后， 会议接入装置利用第一会话向 终端发送提示输入会议号码的信息。 该过程可以使用 IVR (Interactive Voice Response, 互动式语音应答） 来实现。
步驟 410， 接收终端发送的会议号码；
终端可以通过已经建立的第一会话或者 SIP协议中的 INFO消息来向会议 接入装置发送其要加入会议的会议号码。会议接入装置对应地接收终端发送的 会议号码。
会议号码通常包括会议号和会议密码两部分， 具体可以为下述两种形式中 的任意一种： 第一， 会议号和会议密码分开的形式， 如 012345#8888， 012345 为会议号， 8888为会议密码， #为分隔符； 第二， 会议号和会议密码结合的形 式， 如 0123458888， 012345为会议号， 8888为会议密码。
步驟 411， 在至少两个会议接入号中查询与会议号码对应的会议接入号； 会议接入装置可以预先存储会议号码和会议接入号之间的对应关系。该对 应关系可以是会议接入装置在步驟 405中生成并存储的关系。
当会议接入装置接收到终端发送的会议号码之后， 查询与会议号码对应的 会议系统的会议接入号。
步驟 412， 向终端发送呼叫转移请求， 呼叫转移请求的转移目标字段携带 查询到的会议接入号和会议号码；
在会议接入装置查询到与会议号码对应的会议接入号之后， 会议接入装置 向终端发送 REFER请求 （呼叫转移请求）， 该 REFER请求中携带有查询到的 会议接入号和会议号码， 比如， 会议接入装置向终端发送 REFER 请求， 该 REFER请求的头域中携带有 60681#0123458888#，其中， 60681为会议接入号， 0123458888为会议号码。 呼叫控制网络可以将该 REFER路由送至终端。
步驟 413， 终端根据呼叫转移请求中携带的会议接入号， 向对应的会议系 统发送携带有会议号码的呼叫请求来与会议系统建立第二会话。
终端接收到该 REFER请求之后， 可以根据呼叫转移请求中携带的会议接 入号， 重新向对应的会议系统发送携带有会议号码的呼叫请求。 具体地讲， 本 步驟可以包括如下子步驟：
第一， 终端根据 REFER请求中的会议接入号向会议系统发送 INVITE 消息，比如 INVITE 60681#0123458888#,该 INVITE还携带有终端的媒体信息； 第二， 会议系统接收到该 INVITE消息之后， 向终端反馈 200 OK消息， 该 200 OK携带有会议系统的媒体信息；
第三， 终端和会议系统之间通过 INVITE消息和 200 OK消息携带的符 合 SDP 要求的媒体通道参数来进行媒体通道的协商， 从而建立用于参加会议 的媒体通道， 也即终端与会议系统建立第二会话。 之后， 会议系统可以根据会 议号码将终端接入对应的会议中。
终端与会议系统建立第二会话之后， 终端还可以主动向会议接入装置发送 BYE信息，该 BYE信息可以由呼叫控制网络路由送达至会议接入装置，该 BYE 信息用于终端终止与会议接入装置之间建立的第一会话。
综上所述， 本实施例提供的会议接入方法， 通过会议接入装置向终端发送 呼叫转移请求来指示终端与对应的会议系统建立第二会话， 以便终端利用第二 会话参加会议， 解决了现有技术中用户参加不同的会议系统中的会议时， 需要 输入不同的会议接入号的问题， 达到了终端通过一个统一接入号和不同的会议 号码就可以接入不同的会议系统参加会议的效果。 由于本发明实施例提供的会议接入方法中， 会议接入装置指示终端与会议 系统建立第二会话存在两种实现方式， 为了对第二种实现方式进行更为详细地 描述， 请参考如下实施例：
请参考图 5， 其示出了本发明另一实施例提供的会议接入方法的方法流程 图。 本实施例以该会议接入方法应用于图 1所示的会议接入装置 103来举例说 明， 该会议接入方法可以包括图 3所示会议预约方法， 该会议接入方法包括： 步驟 501至 506， 可以参考步驟 301至步驟 306所示；
步驟 507， 会议接入装置接收终端发送的呼叫请求， 该呼叫请求携带终端 的媒体信息和与会议接入装置对应的统一接入号；
在本实施例中， 用户在接入会议时， 只使用统一接入号即可， 该统一接入 号为会议接入装置的接入号。 具体地讲， 当需要接入会议时， 终端可以根据统 一接入号向会议接入装置发送呼叫请求。呼叫控制网络可以根据统一接入号将 该呼叫请求路由送达至会议接入装置。 此时， 会议接入装置接收终端的呼叫请 求。具体地讲，该呼叫请求可以是 SIP协议中的 INVITE (邀请）消息，该 INVITE 消息携带有终端的媒体信息， 终端的媒体信息通常包括： 终端的 IP 地址、 端 口号、 媒体类型、 媒体格式和传输协议。
步驟 508， 向终端发送携带会议接入装置的媒体信息的呼叫响应， 以建立 与终端的第一会话；
会议接入装置接收到终端发送的呼叫请求之后， 可以得到终端的媒体信 息。 此时， 会议接入装置向终端发送携带自身的媒体信息的呼叫响应， 与终端 进行媒体通道的协商， 来与终端之间建立第一会话。 该呼叫响应可以是 SIP协 议中的 200 OK消息， 该 200 OK消息携带有会议接入装置的媒体信息， 会议 接入装置的媒体消息通常包括： 会议接入装置的 IP地址、 端口号、 媒体类型、 媒体格式和传输协议。 也即， 终端和会议接入装置之间可以通过 INVITE消息 和 200 OK消息中携带的符合 SDP要求的媒体信息来进行媒体通道的协商，从 而建立用于发送提示输入会议号码的媒体通道 （也即第一会话）。
步驟 509， 利用第一会话发送用于提示输入会议号码的信息；
在会议接入装置与终端建立第一会话之后， 会议接入装置利用第一会话向 终端发送提示输入会议号码的信息。 该过程可以使用 IVR (Interactive Voice Response, 互动式语音应答） 来实现。
步驟 510， 接收终端发送的会议号码；
终端可以通过已经建立的第一会话或者 SIP协议中的 INFO消息来向会议 接入装置发送其要加入会议的会议号码。会议接入装置对应地接收终端发送的 会议号码。
会议号码通常包括会议号和会议密码两部分， 具体可以为下述两种形式中 的任意一种： 第一， 会议号和会议密码分开的形式， 如 012345#8888， 012345 为会议号， 8888为会议密码， #为分隔符； 第二， 会议号和会议密码结合的形 式， 如 0123458888， 012345为会议号， 8888为会议密码。
步驟 511， 在至少两个会议接入号中查询与会议号码对应的会议接入号； 会议接入装置可以预先存储会议号码和会议接入号之间的对应关系。该对 应关系可以是会议接入装置在步驟 505中生成并存储的关系。
当会议接入装置接收到终端发送的会议号码之后， 查询与会议号码对应的 会议系统的会议接入号。
步驟 512， 根据查询到的会议接入号向对应的会议系统发送携带有会议号 码和终端的媒体信息的呼叫请求；
会议接入装置根据查询到的会议接入号向对应的会议系统发送携带有会 议号码和终端的媒体信息的呼叫请求。 具体地讲， 会议接入装置根据查询到的 会议接入号向会议系统发送 INVITE消息， 比如 INVITE 60681#0123458888#。 需要说明的是， 该呼叫请求中携带有终端的媒体信息， 终端的媒体信息可以由 步驟 507获得。 步驟 513， 接收会议系统反馈的媒体信息；
然后， 会议接入装置可以接收到会议系统的 200 OK消息， 该 200 OK消 息携带有会议系统反馈的符合 SDP要求的媒体信息。
步驟 514， 向终端发送修改会话请求， 该修改会话请求中携带有会议系统 反馈的媒体信息；
会议接入装置接收到会议系统反馈的媒体信息之后， 向终端发送 re-INVITE (修改会话请求） 消息， 该 re-INVITE 消息将建立第一会话时会议 接入装置向终端发送的会议接入装置的媒体信息修改为会议系统反馈的媒体 信息。
步驟 515， 终端将建立第一会话时接收到的会议接入装置的媒体信息修改 为会议系统的媒体信息， 从而与会议系统建立第二会话。
终端接收到该 re-INVITE消息之后， 根据该 re-INVITE消息携带的会议系 统反馈的媒体信息修改与会议接入装置建立的第一会话， 来与会议系统建立第 二会话。 也即， 终端将建立第一会话时接收到的会议接入装置的媒体信息修改 为 re-INVITE消息中携带的会议系统的媒体信息， 从而与会议系统建立第二会 话。 终端接收到该 re-INVITE消息之后， 还可以向会议接入装置反馈 200 OK 消息， 该 200 OK消息携带有终端的媒体信息。 但事实上， 终端的媒体信息已 经由会议接入装置在步驟 510中发送给会议系统， 会议系统的媒体信息则由会 议接入装置在步驟 512中发送给终端， 所以在修改会话请求的重协商过程中， 新建立的媒体通道为终端与会议系统之间的媒体通道， 第一会话实质上已经被 修改为终端与会议系统之间的第二会话。 之后， 会议系统可以根据会议号码将 终端接入对应的会议中。
综上所述， 本实施例提供的会议接入方法， 通过会议接入装置向终端发送 修改会话请求来指示终端与对应的会议系统建立第二会话， 以便终端利用第二 会话参加会议， 解决了现有技术中用户参加不同的会议系统中的会议时， 需要 输入不同的会议接入号的问题， 达到了终端通过一个统一接入号和不同的会议 号码就可以接入不同的会议系统参加会议的效果。 请参考图 6， 其示出了本发明一个实施例提供的会议接入装置的结构方框 图。 该会议接入装置包括会话建立模块 620、 会议号码接收模块 640、 会议接 入号查询模块 660和接入指示模块 680。 会话建立模块 620， 用于接收终端发送的呼叫请求， 所述呼叫请求携带所 述终端的媒体信息和与所述会议接入装置对应的统一接入号， 并用于向所述终 端发送携带所述会议接入装置的媒体信息的呼叫响应以建立与所述终端的第 一会话。
