( Converged IP Messaging , 筒称为 CPM )的方法， 具体是向群组发送大消息 模式 CPM消息 （ Large Message Mode CPM Message ) 的方法。 背景技术
CPM是开放移动联盟（ Open Mobile Architecture ,筒称为 OMA )于 2005 年提出的， 其目的是实现多种消息业务的互通， 提供统一消息业务， 以及完 善一致并且方便的消息业务体验。 CPM融合现有的多种消息业务， 包括即时 消息（ Instant Message, 筒称为 IM )、 一键通 ( Push— To— Talk over Cellular, 筒称为 POC )、 移动电子邮件（Mobile E-Email, 筒称为 MEM )、 短消息业务 ( Short Messaging Service, 筒称为 SMS )、 彩信业务 ( Multimedia Messaging Service , 筒称为 MMS ) 等。 目前， OMA正在制定 CPM VI.0规范。 CPM的主体业务形式包括： 基 于寻呼模式 ( page-mode ) 的 CPM 消息、 基于会话模式 ( session-mode ) 的 大消息模式 CPM消息 ( Large Message Mode CPM Message )、基于 session的 其他 CPM会话业务。 在用户正常使用这些业务前， 需要注册登录到 CPM系 统， 即通常所说的 "上线"。 收发双方的 CPM客户端 （ CPM Client ) 与 CPM引擎 （ CPM Enabler ) 之间使用 （ Session Initiation Protocol, 筒称为 SIP ) 消息 （ SIP Message )传 递 page-mode消息。 当发送方终端需要发送一个大消息模式 CPM消息时 , 如果消息的大小超过了限制（例如，大于 1300字节），则不能用 SIP MESSAGE 承载。
CPM业务支持预设群组 （ CPM Pre-defined Group ) 与临时群组 ( CPM Ad-hoc Group ), CPM用户可以向某一个临时群组或者预设群组发送 CPM寻 呼消息， 但当消息大 、超过一定限额时， 则不能用 SIP MESSAGE承载。 在相关技术中，尚未有向某一个临时群组或者预设群组发送大消息模式 CPM消息的解决方案。 发明内容 针对相关技术中现有技术中 CPM客户端无法向群组中的接收方发送大 消息模式 CPM 消息的问题而提出本发明， 为此， 本发明的主要目的在于提 供一种改进的一种向群组发送大消息模式 CPM 消息的方法， 以解决上述问 题至少之一。 根据本发明的一个方面， 提供了一种向群组发送大消息模式融合 IP消 息 CPM消息的方法。 居本发明的向群组发送大消息模式融合 IP消息 CPM消息的方法， 用 于发送方 CPM客户端向目标群组发送大消息模式 CPM消息， 其中， 该方法 包括： 发送方 CPM客户端发送大消息模式 CPM消息会话邀请消息 , CPM控 制功能实体接收到会话邀请消息后， 针对群组的每一个接收方地址， 均发送 会话邀请消息； 接收方 CPM客户端接收会话邀请消息，与控制功能实体进行媒体协商， 控制功能实体与发送方 CPM客户端进行媒体协商 ,确立发送方 CPM客户端 与接收方 CPM客户端之间的媒体传输链路； 和 /或， 互通功能实体接收会话邀请消息， 与控制功能实体进行媒体协商， 控制 功能实体与发送方 CPM客户端进行媒体协商，确立发送方 CPM客户端与控 制功能实体之间的媒体传输链路； 发送方 CPM客户端通过媒体传输链路， 将大消息模式 CPM消息的内 容发送到接收方 CPM客户端和 /或互通功能实体； 发送方 CPM客户端或控制功能实体或接收方 CPM客户端或互通功能 实体发起大消息模式 CPM消息会话结束流程。 才艮据本发明的另一方面， 提供了一种向群组发送大消息模式融合 IP消 息 CPM消息的系统。 居本发明的向群组发送大消息模式融合 IP消息 CPM消息的系统，用 于向目标群组发送大消息模式 CPM消息， 其中， 该系统包括： 发送方 CPM 客户端体和目的端参与功能实体、接收方 CPM客户端、 CPM控制功能实体、 源端参与功能实体， 其中, 发送方 CPM客户端 , 用于发送大消息模式 CPM消息的会话邀请消息 , 其中， 会话邀请消息中携带有进行协商的会话描述协议 SDP会话描述参数； 还用于接收会话邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输 链路； 还用于基于已建立的媒体传输链路发送媒体传输请求 MSRP SEND; 源端参与功能实体， 即发送方归属的参与功能实体， 用于接收并发送会 话邀请消息； 还用于接收并发送成功响应消息 SIP 200 OK; 还用于建立媒体 传输链路； 还用于接收媒体传输请求 MSRP SEND; 还用于将媒体传输请求 发送至相邻的 MSRP中继节点； CPM控制功能实体， 用于接收并对目标群组内每一个接收方地址发送 会话邀请消息；还用于接收并发送会话邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于在接收到 MSRP SEND请求后， 基于已建 立的媒体传输链路， 对每一个接收方地址均发送 MSRP SEND请求； 目的端参与功能实体， 即接收方归属的参与功能实体， 用于接收并发送 会话邀请消息；还用于接收并发送会话邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于接收媒体传输请求 MSRP SEND; 还用于 将媒体传输请求发送至相邻的 MSRP中继节点； 接收方 CPM客户端， 用于接收会话邀请消息； 还用于创建并回复会话 邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于接 收媒体传输请求 MSRP SEND。 进一步地， CPM控制功能实体接收到会话邀请消息时， 临时担任会议 中心。 进一步地 , CPM控制功能实体， 在接收到会话邀请消息时 , 如果接收方是临时群组， CPM控制功能实体， 才艮据会话邀请消息的消 息体中携带的群组成员列表获取接收方地址； 如果接收方是预设群组， CPM控制功能实体， 从文档服务器中获取接 收方地址。 进一步地， 接收方地址为 CPM系统接收方地址 CPM Adress或非 CPM 系统接^:方地址 non-CPMA dress。 进一步地， CPM控制功能实体接收到会话邀请消息时， 作为背靠背用 户代理 B2BUA。 进一步地， CPM控制功能实体当接收到 SIP 200OK响应后， CPM控制 功能实体在 SIP 200OK响应里附力口 "isfocus" 特征参数。 进一步地， 当接收到 SIP 200OK响应后， CPM控制功能实体发送 SIP ACK最终确认消息。 进一步地， CPM控制功能实体当接收到 SIPACK后， 根据 SDP提供的 信息， 确定与相邻节点 hop的链路。 进一步地， 发送方 CPM客户端还用于发送 BYE请求 , CPM控制功能 实体当接收到来自发送方的 BYE请求后， CPM控制功能实体针对目标群组 内的每一个接收方地址均发送 BYE请求。 通过本发明的上述至少一个方案，对于群组内的 CPM系统可达接收方， 通过发送大消息模式 CPM消息的会话邀请消息建立发送方 CPM客户端与目 标群组中的 CPM系统的可达接收方的 CPM客户端之间的媒体传输链路， 将 该大消息模式 CPM消息的内容发送给接收方 CPM客户端。 对于群组内的 CPM系统不可达接收方 （ not-Available CPM Address ) 或群组内的非 CPM用户接收方 （ non-CPM Address ), 一方面 , 通过建立控 制功能实体 ( Controlling Function, 筒称为 CF ) 与发送方客户端之间媒体传 输链路、 控制功能实体与互通功能实体 IWF ( Interworking Function )之间的 媒体传输链路。 基于以上链路可以将大消息模式 CPM 消息从发送方客户端 实时或准实时或非实时发送至互通功能实体。 另一方面， 互通功能实体可以 通过它与非 CPM 系统 （ non-CPM )之间的媒体转换与传输接口将大消息模 式 CPM消息实时或准实时或非实时传送到非 CPM系统中。通过以上两个步 骤， 可以完成发送方到非 non-CPM系统 （和 /或 non-CPM系统用户客户端） 的大消息模式 CPM 消息的传送。 该功能可以根据用户设置和运营商策略进 行启用与否。 通过以上方案， 可以解决现在技术中无法向群组传输大消息模式 CPM 消息的问题， 提高了用户体验。 本发明的其它特征和优点将在随后的说明书中阐述， 并且， 部分地从说 明书中变得显而易见， 或者通过实施本发明而了解。 本发明的目的和其他优 点可通过在所写的说明书、 权利要求书、 以及附图中所特别指出的结构来实 现和获得。 附图说明 附图用来提供对本发明的进一步理解， 并且构成说明书的一部分， 与本 发明的实施例一起用于解释本发明 , 并不构成对本发明的限制。 在附图中： 图 1为本发明实施例， 以群组内一个 CPM系统内可达接收方为例， 大 消息模式 CPM消息向群组发送方法流程图； 图 2为本发明实施例， 以群组内一个 CPM系统内可达接收方为例， 发 送方 CPM客户端与接收方 CPM客户端之间媒体链路建立过程示意图； 图 3为本发明实施例， 以群组内一个 CPM系统内可达接收方为例， 发 送方 CPM客户端向接收方 CPM客户端发送大消息模式 CPM消息的内容的 流程图； 图 4为本发明实施例， 以群组内一个 CPM系统内可达接收方为例， 发 送方 CPM客户端向接收方 CPM客户端发送大消息模式 CPM消息的媒体链 路的分段示意图； 图 5为本发明以群组内一个 CPM系统内可达接收方为实施例的消息流 程图； 图 6为 居本发明实施例的大消息模式 CPM消息向群组传输系统的控 制功能实体对信令及媒体控制的流程图； 图 7为根据本发明实施例的大消息模式 CPM消息向群组传输系统的控 制功能实体的功能示意图。 具体实施方式 功能相克述 由于大消息模式 CPM消息所占的空间较大， 不能直接使用 SIP消息进 行 载 , 与 page-mode模式 CPM消息传送方式不同 , 大消息模式 CPM消息 传送路径分为信令路径和媒体路径， 即信令沿信令路径传送， 媒体沿媒体路 径传送。 因此， 在本发明实施例中， 在传输大消息模式 CPM 消息时， 先使 用大消息模式 CPM消息的会话邀请消息 （INVITE ) 建立发送方 CPM客户 端与接收方 CPM客户端之间的会话 , 完成媒体协商 , 建立发送方 CPM客户 端与接收方 CPM客户端之间的传输链路， 通过建立的传输链路， 使用消息 会话中继协议 ( Message Session Relay Protocol , 筒称为 MSRP ) 向上述接收 方 CPM客户端传送该大消息模式 CPM消息的消息体，即 CPM消息的内容。 大消息模式 CPM消息向群组发送， 群组内可能包含多个接收方地址， 接收方地址可能为 CPM接收方地址（ CPM Address ), 也可以为非 CPM接收 方地址（ non-CPM Address )。 对于 CPM接收方地址 , 可能为可达 CPM接收 方地址， 也可能是不可达接收方地址。 因此， 本发明的实施例中， 控制功能 实体完成对群组的集中管理和控制， 担任临时会议中心角色， 并按照背靠背 用户代理（ B2BUA )原贝' J处理， 同时充当用户代理客户端（ User Agent Client, 筒称为 UAC ) 和用户代理服务器 （User Agent Server, 筒称为 UAS ) 两个角 色， 即当接收到请求时， 做为服务器给予响应， 但为了获知给予何种响应， 会产生一个新的请求。 控制功能实体接收到会话邀请消息后， 向群组内的每 一个接收方 （ CPM Address和 non-CPM Address ) 均发送会话邀请消息， 从 而在目的域， 控制功能实体与每一个接收方客户端 （对于 non-CPM Address 或者不可达 CPM用户地址是指互通功能实体） 建立信令和媒体传输路径。 由此， 完成发送方客户端与群组中的每一个接收方客户端之间的大消息模式 CPM消息的传送。 需要说明的是，本发明实施例中所称的大消息模式 CPM消息，为 OMA 制定的 CPM规范中其大小超过预设限制 （比如， 1300个字节） 的 CPM消 息 , 该大消息模式 CPM消息不能直接使用 SIP消息进行承载。 在不冲突的情况下， 本申请中的实施例及实施例中的特征可以相互组 合。 以下结合附图对本发明的优选实施例进行说明 , 应当理解 , 此处所描述 的优选实施例仅用于说明和解释本发明， 并不用于限定本发明。 根据本发明实施例， 首先提供了一种大消息模式 CPM消息传输方法， 该方法用于向目标群组发送大消息模式 CPM消息。 图 1为本发明实施例， 以群组内一个 CPM系统内可达接收方为例， 大 消息模式 CPM消息向群组传输方法的流程图。图 6 大消息模式 CPM消息向 群组发送到一般情况。为筒单起见，该图 1和图 6均省略了 SIP/IP Core节点， 事实上图中每两个功能实体之间的信令传输均通过 SIP/IP核心网进行，本省 略并不构成对本发明的限制。 如图 1和图 6所示， 才艮据本发明实施例的大消 息模式 CPM 消息向群组发送的方法主要包括以下步骤 （步骤 S101 -步骤 S107 ): 步骤 S101 - S104:发送方 CPM客户端向某一个预设群组或者临时群组 发送大消息模式 CPM消息的会话邀请消息， CPM控制功能实体接收会话邀 请消息， CPM控制功能实体通过获取预设群组或者临时群组的接收方地址， 即如果接收方为临时群组， 解析会话邀请消息的消息体中携带的 MIME <resource-lists>获取群组成员列表； 如果接收方预设群组， 从文档服务器 [OMA-XDM-Shared-Group]获取群组成员地址。 CPM控制功能实体逐一向每 个接收方发送会话邀请消息。 最终 , CPM客户端或者互通功能实体接收到会 话邀请消息。 在 S101、 S102、 S103、 S104 步骤中的邀请消息， 邀请消息的 Call-ID 可以不同， S101、 S102、 S103、 S104 步骤中的邀请消息可以不是同一个邀 请消息， 但考虑到筒化描述和并不产生歧义， 本发明某些文字表述中并不特 别强调同一个传输路径上的同一个方法的 SIP消息在不同对话中的消息相无念 引用的差异化， 如无特殊说明， 可才艮据发明的上下文理解。 步骤 S105: 对于群组内 CPM系统可达接收方地址， 接收方 CPM客户 端接收到会话邀请消息 , 与发送方 CPM客户端进行协商 , 确立发送方 CPM 客户端与接收方 CPM客户端之间的媒体传输链路； 或者， 本步骤可以描述 为 ,接收方 CPM客户端接收到会话邀请消息后 ,与控制功能实体（ Controlling Function, 筒称为 CF )进行协商， 确立接收方与控制功能实体之间传输链路， 控制功能实体与发送方客户端进行协商， 确立与发送方 CPM客户端之间的 传输链路。 对于群组内的 CPM 系统不可达接收方地址 （ not- Available CPM Address ) 或群组内的非 CPM用户接收方地址 （ non-CPM Address ), 互通功 能实体接收到会话邀请消息， 一方面， 确立控制功能实体与发送方客户端之 间媒体传输链路， 另一方面确立控制功能实体与互通功能实体之间的媒体传 输链路。 步骤 S106: 发送方 CPM客户端通过上述媒体传输链路， 将大消息模式 CPM消息的内容发送到接收方客户端或者 non-CPM系统； 步骤 S107: 发送方 CPM客户端或控制功能实体或接收方 CPM客户端 或者互通功能实体发起大消息模式 CPM消息会话结束流程。 以下进一步描述上述各处理的细节。
(一） 步骤 S101 - S104 为筒单起见， 该图中省略了 SIP/IP Core节点， 事实上图中每两个功能 实体之间的信令传输均通过 SIP/IP核心网进行， 本省略并不构成对本发明的 限制。 在具体实施过程中， 在发送方 CPM客户端将会话邀请消息发送至接 收方 CPM客户端的过程中， 如图 5所示， 每个网元在接收到会话邀请消息 后， 都可以将给向其发送该会话邀请消息的网元返回一个响应消息 （ 100 Trying )。
(二） 步骤 S105 在具体实施过程中， 确立的发送方 CPM客户端与接收方 CPM客户端 之间的媒体传输链路可以为 MSRP协议链路， 具体地， 对于群组内 CPM系 统可达接收方地址 , 建立以下分段 MSRP媒体传输链路： 接收方 CPM客户端与第二参与功能实体之间的第一媒体传输链路； 如 果群组内有多个归属于第二参与功能实体的接收方地址，则每个接收方 CPM 客户端均与第二参与功能实体建立媒体传输链路； 第二参与功能实体与控制功能实体之间的第二媒体传输链路；如果群组 内有多个归属于第二参与功能实体的接收方地址， 则第二参与功能实体与控 制功能实体建立多条媒体传输链路； 控制功能实体与第一参与功能实体之间的第三媒体传输链路； 第一参与功能实体与发送方 CPM客户端之间的第四媒体传输链路。 对于群组内的 CPM系统不可达接收方地址， 建立以下分段 MSRP媒体 传输链路： 互通功能实体与第二参与功能实体之间第一媒体传输链路； 第二参与功能实体与控制功能实体之间的第二媒体传输链路； 控制功能实体与第一参与功能实体之间的第三媒体传输链路； 第一参与功能实体与发送方 CPM客户端之间的第四媒体传输链路。 对于群组内的非 CPM系统接收方地址 , 建立以下分段 MSRP媒体传输 链路： 互通功能实体与控制功能实体之间第一媒体传输链路； 控制功能实体与第一参与功能实体之间的第三媒体传输链路； 第一参与功能实体与发送方 CPM客户端之间的第四媒体传输链路。 图 6中并没绘出控制功能实体对来自源端即参与功能实体 A会话邀请 消息的响应消息， 控制功能实体按照背靠背用户代理 (B2BUA)处理， 在大消 息模式会话期间担任临时会议中心的角色 , 包括以下几种解决方案： 方案一： 控制功能实体接收到会话邀请消息后，一方面对会话邀请消息 进行群组分流处理， 即获取群组每一个接收方地址并逐一向群组内每一个接 收方发送会话邀请消息。 另一方面， 控制功能实体对接收会话邀请消息回成 功响应。 方案二： 控制功能实体接收到会话邀请消息后， 对会话邀请消息群组分 流处理， 当接收到来自目的域的第一个成功响应后， 再针对原会话邀请消息 回复成功响应。 方案三： 控制功能实体接收到会话邀请消息后， 对会话邀请消息群组分 流处理， 当接收到所有的来自目的域的成功响应后， 再针对原会话邀请消息 回复成功响应。
(三） 步骤 S106 在确立了发送方 CPM客户端与接^：方 CPM客户端 （或者互通功能实 体）之间的媒体传输链路后 , 发送方 CPM客户端通过确立的媒体传输链路 , 将大消息模式 CPM消息的消息体（即该大消息模式 CPM消息的内容）发送 到接收方 CPM客户端 （或互通功能实体）， 具体地， 如图 3和图 6所示， 该 步骤的处理可以包括以下步骤： 步骤 1 , 发送方 CPM客户端通过上述第四媒体传输链路， 将大消息模 式 CPM 消息的内容发送到第一参与功能实体， 按照 MSRP 协议逐块发送 MSRP SEND; 步骤 2 , 第一参与功能实体接收到 MSRP SEND请求后， 通过第三媒体 传输链路， 将 MSRP SEND请求发送控制功能实体； 步骤 3 , 控制功能实体接收到 MSRP SEND , 将 MSRP SEND请求发送 到第二参与功能实体； 如果群组内有多个归属于第二参与功能实体的接收方 地址， 则逐一发送 MSRP SEND请求。 如果群组内有非 CPM系统的接收方 地址， 则控制功能实体将 MSRP SEND请求按照已建立好的链路发送到互通 功能实体； 步骤 4 , 第二参与功能实体通过第一媒体传输链路将 MSRP SEND发送 到接收方 CPM客户端， 或者， 如果群组内有 CPM系统不可达用户， 则第二 参与功能实体通过第一媒体传输链路将 MSRP SEND发送至互通功能实体。
(四） 步骤 S107 在发送方 CPM客户端将大消息模式 CPM消息的内容发送到上述接收 方 CPM客户端之后， 将发起会话结束流程， 具体地， 会话结束流程可以由 发送方 CPM客户端发起也可以控制功能实体发起也可以由接收方 CPM客户 端发起或者由互通功能实体发起， 以下分别进行描述。 由发送方 CPM客户端发起会话结束流程 为筒单起见， 该图中省略了 SIP/IP Core节点， 事实上图中每两个功能 实体之间的信令传输均通过 SIP/IP核心网进行，本省略并不构成对本发明的 限制。 具体地， 如图 5和图 6所示， 由发送方 CPM客户端发起会话结束流 程主要包括以下步骤： 步骤 1 ,发送方 CPM客户端发送指示大消息模式 CPM消息会话结束的 指示消息， 该消息经由 SIP/IP核心网路由至第一参与功能实体； 步骤 2, 第一参与功能实体接收到会话结束的指示消息， 并发送会话结 束的指示消息， 该消息经由 SIP/IP核心网路由至 CPM控制功能实体； 步骤 3 , CPM控制功能实体接收到会话结束指示消息， 按照群组接收 方地址， 逐一对每一个接收方发送会话结束指示消息， 该消息经过 SIP/IP核 心网路由至第二参与功能实体 （对于 CPM接收方地址） 或者选择功能实体 (对于非 CPM接收方地址）。 步骤 4, 第二参与功能实体接收会话结束指示消息， 发送会话结束指示 消息， 该消息经由 SIP/IP核心网路由至接收方 CPM客户端； 对于 CPM系统 内不可达用户， 该消息被路由至互通功能实体； 步骤 5 , 接收方 CPM客户端接收会话结束指示消息， 发送响应消息， 该消息经由 SIP/IP核心网路由至第二参与功能； 步骤 6 ,第二参与功能实体接收并发送响应消息，该消息消息经由 SIP/IP 核心网路由至 CPM控制功能实体； 步骤 3 -步骤 6以一个 CPM系统内可达接收方为例。 对于 CPM系统内不可达接收方地址，会话结束指示消息传输路径为 CF → PF→ISF→IWF。 响应路径则沿相反方向传输。 对于非 CPM系统接收方地址， 会话结束指示消息传输路径为 CF→ISF →IWF。 响应路径则沿相反方向传输。 步骤 7 , CPM控制功能实体发送响应消息， 该消息经由 SIP/IP核心网 路由至第一参与功能； 对于群组内多个接收方的情况， CPM控制功能实体仅 发送一个结束会话响应消息到源域； 步骤 8 , 第一参与功能实体接收并且发送响应消息， 该消息经由 SIP/IP 核心网路由至发送方 CPM客户端。 以上给出一个会话结束流程的一个实施例， CPM控制功能实体可以接 收到会话结束请求响应后， 即向源域回复响应， 即在步骤 3中执行。 从而替 代步骤 7 。 由接收方 CPM客户端发起会话结束流程 接收方发 CPM客户端起起会话结束流程， 整个过程与发送方 CPM客 户端起起会话结束流程相反， 所不同的是， 如果发出结束会话请求的接收方 客户端不是唯一个当前参与会话的接收方， 即此时具有其他接收方客户端存 在， 则控制功能实体接收到结束会话请求后， 并不向源端发起结束会话请求， 控制功能实体向该接收方返回结束会话成功响应。 由接收方控制功能实体发起会话结束流程 控制功能实体临时担任会议中心角色，可以随时向群组内的每一个成员 (具体是成员对应的地址） 发起会话结束流程。 通过本发明实施例中的上述大消息模式 CPM消息传输方法， 可以向目 标群组中接收方发送大消息模式 CPM 消息。 目标群组中包括多个接收方地 址， 这些接收方中可能包括 CPM系统可达接收方地址、 还可能包括 CPM系 统不可达的接收方地址， 还可能包括非 CPM系统接收方地址。 为进一步理解本发明实施例提供的技术方案的具体实施方式，下面通过 具体实施例进行说明。 在以下的实施例中 ,不失一般性 ,個设发送方 CPM客户端为 CPM Client A, 有效绑定地址为 CPM Address A、 发送方归属的第一参与功能实体为 Participating Function A、 目标群组内的 CPM系统可达接收方的 CPM客户端 为 CPM Client B和 CPM Client C,绑定地址分别为 CPM Address B和 CPM Address C;可达接收方归属的第二参与功能实体分别为 Participating Function B和 Participating Function C; 目标群组对应的 CPM控制功能实体为 CPM Controlling Function X。 在该实施例中， 1设群组内含有一个非 CPM系统接 收方地址， 叚设为地址为 non-CPM Address D , 对应的选择功能实体和互通 功肯 ¾实体为 Interworking Selection Function- Y1和 Interworking Function-Yl。 在该实施例中 , 再^!设群组内含有一个 CPM 系统内不可达地址 CPM Address D,個—设归属 Participating Function D, 对应的选择功能实体和互通功 肯 ¾实体为 Interworking Selection Function- Y2和 Interworking Function- Y2„ 在本实施例中， 由 CPM Client A发起会话结束流程。 图 6为本实施例中 CPM Client A向目标群组传输大消息模式 CPM消息 的流程图， 如图 6所示， CPM Client A向目标群组内传输大消息模式 CPM 消息主要包括以下步骤： 步骤 1 , CPM Client A向某个预设群组或临时群组发送会话邀请消息 , 会话消息经由 SIP/IP核心网路由至 Participating Function A; 步骤 2 , Participating Function A接^:会话邀请消息， 产生并发送会话邀 请消息， 该会话邀请消息由 SIP/IP核心网路由至 CPM Controlling Function X； 步骤 3 , CPM Controlling Function X接收到会话邀请消息， 才艮据群组内 接收方地址， 如果接收方为临时群组， 根据会话邀请消息的消息体中携带的 群组成员列表， MIME <resource-lists>, 向每个成员发送会话邀请消息。 如果接收方预设群组， 从文档服务器， 如 [OMA-XDM-Shared-Group] , 获取 群组成员地址，向每个成员发送会话邀请消息。本实施例中， CPM Controlling Function X 向接 4欠方地址 CPM Address B、 CPM Address C、 non-CPM Address D发送会话邀请请求消息 , 各个请求消息经由 SIP/IP核心网分别路 由至 Participating Function B、 Participating Function C和 Participating Function D以及 Interworking Selection Function-Yl； 步骤 4, Participating Function B接^:会话邀请消息、 产生并且发送会话 邀请消息， 会话消息经由 SIP/IP核心网路由至 CPM Client B； 步骤 5 , Participating Function C接收会话邀请消息、 产生并且发送会话 邀请消息， 会话消息经由 SIP/IP核心网路由至 CPM Client C; 步骤 6 , Interworking Selection Function-Yl接 4欠并发送会话邀请消息 , 该会话消息经由 SIP/IP核心网路由至 Interworking Function-Yl； 步骤 7, CPM Client B接收会话邀请消息， 发送成功响应， 该成功响应 经由 SIP/IP Core B向路由至 Participating Function B； 步骤 8 , Participating Function B接 4欠成功响应消息 , 并发送成功响应的 最终确认消息， 该确认消息经由 SIP/IP Core B路由至 CPM Client B; 步骤 9, CPM Client B接收该最终确认消息， 根据 SDP信息指示， 建立 与相邻的 MSRP中继点 , 即实际为与 Participating Function B之间的第一媒 体传输链路（可以为 TCP链路 )； 如果当前 CPM Client B与 Participating Function B之间存在有 TCP传输 链路 , 则也可以选择一条已有的 TCP传输链路作为大消息模式 CPM消息媒 体传输链路。 步骤 10, Participating Function B发送成功响应消息，该消息经由 SIP/IP 核心网路由至 CPM Controlling Function X。 步骤 8到步骤 10 时间上并没有严格先后时序关系， 即 Participating Function B发送成功响应 SIP 200 OK和发送 SIPACK没有严格的时间次序。 步骤 11 , CPM Controlling Function X接收成功响应消息 , 并发送成功 响应的最终确认消息， 该确认消息经由 SIP/IP 核心网路由至 Participating Function B; 步骤 12, Participating Function B接收该最终确认消息 , 才艮据 SDP信息 指示， 建立与相邻的 MSRP中继点 , 即实际为与 CPM Controlling Function X 之间的第二媒体传输链路（可以为 TCP链路 )； 口果当前 Participating Function B与 Controlling Function X之间存在有
TCP传输链路，则也可以选择一条已有的 TCP传输链路作为大消息模式 CPM 消息媒体传输链路。
CPM Client C与 Participating Function C之间以及 Participating Function C与 Controlling Function X之间的媒体传输链路建立过程与步骤 7 -步骤 12 相似。 不再赘述。 步骤 13 , CPM Controlling Function X发送成功响应消息 , 该消息经由 通过 SIP/IP 4亥心网路由至 Participating Function A; 步骤 14, Participating Function A接 4欠上述成功响应消息， 发送成功响 应的最终确认消息， 该确认消息经由 SIP/IP核心网路由至 CPM Controlling Function X； 步骤 15 , CPM Controlling Function X接收该最终确认消息 , 才艮据 SDP 信息指示， 建立与相邻的 MSRP 中继点， 即实际为与 CPM Participating Function A之间的第三媒体传输链路（可以为 TCP链路）； 同理 ,也可以选择 Participating Function A与 CPM Controlling Function X 之间的现有的媒体传输链路。 步骤 11到步骤 15时间上并没有严格先后时序关系 ,即 CPM Controlling Function X发送成功响应 SIP 200 OK和发送 SIP AC 没有严格的时间次序。 步骤 16 , Participating Function A发送成功响应消息，该消息经由 SIP/IP 核心网路由至 CPM Client A; 步骤 17 , CPM Client A发送成功响应的最终确认消息， 该确认消息经 由 SIP/IP核心网路由至 Participating Function A; 步骤 18 , Participating Function A接收最终确认消息 , 才艮据 SDP信息指 示， 建立与相邻的 MSRP中继点， 即实际为与 CPM Client A之间的第四媒体 传输链路（可以为 TCP链路）； 同理 , 也可以选择 CPM Client A与 Participating Function A现有的媒体 传输链路。 本方案从 CF将整个信令路径和传输链路分为 2部分， 即源域的 CPM
Client A <->Participating Function A<->Controlling Function X部分和目的域 Controlling Function X<-> Participating Function B<->CPM Client B;和 Controlling Function X<-> Participating Function C<->CPM Client C;和 Controlling Function X<-> Interworking Selection Function- Y 1 <->Interworking Function-Yl ; 对于群组内的非 CPM系统接收地址 , 目的域一侧的 MSRP传输链路为 互通功能实体 Interworking Function-Yl与 Controlling Function X之间建立。 对于群组内的 CPM不可达地址， 目的域一侧的 MSRP传输链路为互通 功肯 ¾实体 Interworking Function-Yl 与 Participating Function -D之间, 以及 Participating Function— D与 Controlling Function X之间的两条链路。 步骤 19 , 对于 CPM系统可达用户 , CPM Client A通过上述第四媒体传 输链路， 第三媒体传输链路、 第二媒体传输链路、 第一媒体传输链路将大消 息模式 CPM消息的内容 ( CPM Large Message Media )按照 MSRP十办议逐兆 发送给接收方 CPM Client B和接收方 CPM Client C; 对于群组内 CPM 系统不可达接收方地址， 则在目的侧， 沿着的
Controlling Function X 与 Participating Function — D 之间以及 Participating Function D与 Interworking Function-Yl之间的传输链路传输，最终^ 1大消息 模式 CPM消息发送至非 CPM系统。 对于群组内的非 CPM 系统接收地址， 目的 i或一侧沿着 Controlling Function X与 Interworking Function- Yl之间传输链路传输， 最终^ 1大消息模 式 CPM消息发送至非 CPM系统。 步骤 20 , CPM Client A发送会话结束指令消息 SIP BYE , 该消息经由 SIP/IP核心网路由至 Participating Function A; 步骤 21 , Participating Function A接收到会话结束指令消息 BYE , 并发 送 BYE ,该 BYE消息经由 SIP/IP核心网路由至 CPM Controlling Function X； 步骤 22 , Controlling Function X 向每个接收方地址 （ CPM 地址和 non-CPM 地址） 发送会话结束的指示消息； 步骤 22 , Controlling Function X发送 BYE的成功响应消息 , 该消息经 由 SIP/IP核心网路由至 Participating Function A; 步骤 23 , Participating Function A接 4欠 BYE的成功响应消息， 该消息 经由 SIP/IP核心网路由至 Client A; 步骤 22 -步骤 23是由 Controlling Function X给出 BYE响应的例子。 也可以为 Controlling Function X接收到某一个接收方的 BYE成功响应消息之 后 （例如第一个 BYE响应消息） 向源 i或发送 BYE成功响应。 步骤 23 , Participating Function B接收到会话结束指示消息 SIP BYE , 并发送会话结束指示消息 SIP BYE ,该消息 SIP BYE经 SIP/IP核心网路由至 CPM Client B; 步骤 24 , CPM Client B接收会话结束 SIP BYE , 并发送 BYE成功响应 消息 SIP 200 OK , 该消息 SIP 200 OK 经由 SIP/IP Core 核心网路由至 Participating Function B; 步骤 25 , Participating Function B接 4欠会话结束成功响应消息 SIP 200 OK, 并发送结束会话成功响应消息 SIP 200 OK, 该消息 SIP 200 OK经由 SIP/IP核心网路由至 CPM Controlling Function X； 对于 CPM Controlling Function X与 CPM Client C之间的会话结束流程 与上述步骤相似。 根据本发明实施例 , 还提供了一种大消息模式 CPM消息传输系统。 该 系统用于向目标群组发送大消息模式 CPM消息。 如附图所示 , 根据本发明实施例的大消息模式 CPM消息传输系统主要 包括： 发送方 CPM客户端 1、 源端参与功能实体 2、 目标群组的 CPM控制 功能实体 3、 目的端参与功能实体 4、 接收方 CPM客户端 5。 发送方 CPM客 户端， 用于发送大消息模式 CPM 消息的会话邀请消息， 其中， 该会话邀请 消息中携带有进行协商的会话描述协议 SDP会话描述参数；还用于接收会话 邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于基 于已建立的媒体传输链路发送媒体传输请求 MSRP SEND; 源端参与功能实 体， 即发送方归属的参与功能实体， 用于接收并发送会话邀请消息； 还用于 接收并发送成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于接 收媒体传输请求 MSRP SEND; 还用于将媒体传输请求发送至相邻的 MSRP 中继节点； CPM控制功能实体， 用于接收并对目标群组内每一个接收方地址 发送会话邀请消息；还用于接收并发送会话邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于在接收到 MSRP SEND请求后， 基于 已建立的媒体传输链路， 对每一个接收方地址均发送 MSRP SEND请求。 目 的端参与功能实体， 即接收方归属的参与功能实体， 用于接收并发送会话邀 请消息； 还用于接收并发送会话邀请消息的成功响应消息 SIP 200 OK; 还用 于建立媒体传输链路； 还用于接收媒体传输请求 MSRP SEND; 还用于将媒 体传输请求发送至相邻的 MSRP中继节点。 接收方 CPM客户端， 用于接收 会话邀请消息；还用于创建并回复会话邀请消息的成功响应消息 SIP 200 OK; 还用于建立媒体传输链路； 还用于接收媒体传输请求 MSRP SEND。
