S 13、通过所述拨号请求所指示的终端归属网络对应的网内媒体网关完 成通信。 由于所述拨号请求所指示的各终端位于同一网络， 因此可通过该 网络内的网内媒体网关完成通信。
S 14、通过所述拨号请求所指示的各终端的归属网络对应的网间媒体网 关完成通信。
本实施例发起拨号请求的可以是终端上的一个应用模块， 拨号请求所 指示的终端可以包括也可以不包括发起拨号请求的终端本身， 位于任一网 络内的任一终端都可以作为发起拨号请求的终端， 或作为拨号请求所指示 的终端， 因此， 任一网络都配置有对应的、 支持多网接入的网间交换网关 和网间媒体网关。 本实施例的网间交换网关是在多网环境下的交换设备， 支持多种类型网络的接入， 可以有软交换、 硬交换、 或者软硬结合的模式， 具备多网之间协议转义、 交换、 链路保持等功能。 本实施例的网内媒体网 关与传统固化或移动通信网络中的媒体网关类似， 用于完成本网的媒体处 理， 本实施例的网间媒体网关具备协议转义、 交换、 链路保持、 媒体适配、 媒体流控制处理等功能， 由于不同网络媒介间媒体协议的差异， 所以本实 施例的网间媒体网关既要具备网内媒体网关的基本功能， 还要完成网间不 同媒体协议的交互。 本实施例终端之间的通信包括文本、 音频或视频等媒 体数据的传输。 本实施例的网间交换网关可设置在多网核心网上， 或设置 在发起拨号请求的终端归属网络的核心网上； 网间媒体网关可设置在多网 核心网上， 或设置在拨号请求所指示的各终端的归属网络的核心网上。
实施例二
本实施例中的跨网络通信包括电信网、 互联网和广电网等， 图 2为本 发明另一实施例一种跨网络实现终端通信的方法的流程图， 如图 2所示， 该方法包括以下步驟：

523、 点击拨号业务平台发出通信链路建立请求来建立通信链路， 具体 过程为： 点击拨号业务平台解析拨号请求所携带的该拨号请求所指示的各 终端的地址信息， 并根据该拨号请求所指示的各终端的地址信息识别该拨 号请求所指示的各终端的归属网络， 将通信链路建立请求通过该拨号请求 所指示的各终端的归属网络所对应的网间通信网关， 发送至各终端的归属 网络， 各终端的归属网络完成本网内的通信链路的建立。
本实施例的网间通信网关具备多网之间通信链路建立请求的传送、 通 信链路的建立、 协议转义、 交换、 链路保持、 状态报告等功能， 通过网间 通信网关链路的信息会携带媒体信息， 例如 SIP协议。 根据不同的业务， 点击拨号业务平台也可以完成业务的计费、 统计等功能。 针对本实施例多 网环境下的业务处理， 点击拨号业务平台底层的通信核心网需要驱动多种 网络媒介， 在不同网络媒介间建立会话、 完成媒体适配等功能。
524、拨号请求所指示的各终端的归属网络通过与自身所对应的网间通 信网关将链路建立状态上报给点击拨号业务平台， 再由点击拨号业务平台 通过点击拨号能力开放接入网关、 发起拨号请求的终端归属网络对应的网 间交换网关将该链路建立状态上报给发起拨号请求的终端。
S25、 拨号请求所指示的各终端开始传输媒体数据， 如果拨号请求所指 示的各终端位于不同的网络， 则通过拨号请求所指示的各终端的归属网络 对应的网间媒体网关传输媒体数据； 如果拨号请求所指示的各终端位于同 一网络， 则通过拨号请求所指示的终端归属网络对应的网内媒体网关传输 媒体数据。
本实施例的网内媒体网关与传统固化或移动通信网络中的媒体网关类 似， 用于完成本网的媒体处理， 本实施例的网间媒体网关具备协议转义、 交换、 链路保持、 媒体适配、 媒体流控制处理等功能， 由于不同网络媒介 间媒体协议的差异， 所以本实施例的网间媒体网关既要具备网内媒体网关 的基本功能， 还要完成网间不同媒体协议的交互。
本实施例发起拨号请求的可以是终端上的一个应用模块， 拨号请求所 指示的终端可以包括也可以不包括发起拨号请求的终端本身， 位于任一网 络内的任一终端都可以作为发起拨号请求的终端， 或作为拨号请求所指示 的终端， 因此， 任一网络都配置有对应的、 支持多网接入的网间网关， 包 括网间交换网关、 网间通信网关和网间媒体网关， 本实施例的网间网关不 仅是在单一通信媒介中起作用， 更重要的是均具备多种通信媒介间通信协 议的转义、 接续、 链路保持等功能， 网间网关可以有软交换、 硬交换、 或 者软硬结合的模式。 本实施例终端之间的通信包括文本、 音频或视频等媒 体数据的传输。 本实施例的网间网关， 包括网间交换网关、 网间通信网关 和网间媒体网关可设置在多网核心网上， 或设置在各终端归属网络的核心 网上。
