Abstract

Description

异构端点间通道建立方法及装置 技术领域
本申请涉及但不限于通信领域，尤指异构端点间通道建立方法及装置。
背景技术
远程呈现系统是传统的视频会议系统的演进，具备传统视频会议不具备的能力，更清晰逼真，眼神交流，更好的体验等，在系统实现上也有很大的改变。这就导致了传统视频会议异构系统之间的互通方式无法适用于远程呈现系统。
目前，国际上IP(Internet Protocol，网际互连的协议)网络通信的主要标准有H.323和SIP(Session Initiation Protocol，会话初始协议)，两者都对IP电话系统信令提出了完整的解决方案，H.323采用的是传统电话信令模式，包括一系列协议；而SIP借鉴互联网协议，采用基于文本的协议。
当采用H.323协议时，各个不同厂商的多媒体产品和应用可以进行互相操作，用户不必考虑兼容性问题；而SIP协议应用较为灵活，可扩展性强，两者各有侧重。
系统结构差异如下：
首先，从系统结构上分析，在H.323系统中,终端主要为媒体通信提供数据,功能比较简单，而对呼叫的控制、媒体传输控制等功能的实现则主要由网守来完成。H.323系统体现了一种集中式、层次式的控制模式。
而SIP采用Client/Server(客户机/服务器)结构的消息机制，对呼叫的控制是将控制信息封装到消息的头域中,通过消息的传递来实现。因此SIP系统的终端就比较智能化，它不只提供数据,还提供呼叫控制信息,其他各种服务器则用来进行定位、转发或接收消息。这样，SIP将网络设备的复杂性推向了网络终端设备，因此更适于构建智能型的用户终端。SIP系统体现的是一种分布式的控制模式。
相比而言，H.323的集中控制模式便于管理，像计费管理、带宽管理、 呼叫管理等在集中控制下实现起来比较方便，其局限性是易造成瓶颈。而SIP的分布模式则不易造成瓶颈，但各项管理功能实现起来比较复杂。
远程呈现端点有基于H.323的和基于SIP的两种类型，对于如何让这两种异构类型的远程呈现端点之间互通，目前还没有一种较好的解决方式。
