基于NGN的多通讯协议融合性研究
|
摘要
H．323网络、SIP网络和软交换网络在很长时间内将共存，解决多通讯协议网络融合是现阶段通讯研究领域面临的重要的任务。通过NGN可以把多通讯协议的网络融合起来。依据NGN分层的特性，融合性研究自然分层进行。业务层利用低层网络实现业务逻辑功能，首先要解决地址解析和选路的问题，就是把业务层理解的通讯对等端的用户网络标识翻译成为通讯对等端的通讯设备的地址，并把消息传送给它，每次通讯要使用模型来进行一系列交互。在多种网络存在的情况下，地址解析和选路、消息传送和使用模型通讯都与单独网络时的情况不同。
本文的分为如下几个章节：
第一章绪论，介绍研究的背景和内容以及文章的结构。
第二章基于NGN的多通讯协议地址解析和选路的融合，设计了在H．323与SIP两类网络互通的情况下地址解析和选路的方案，两个网络的拓扑结构通过传送TRIP路由信息的方式相互发布和学习。分析了基于NGN的地址解析和选路的情况。设计了在不同网络之间实现协议消息转换的协议中间件方案。
第三章基于NGN的多通讯协议信令的融合，网络融合时不同协议消息要对呼叫模型进行适配。针对SIP协议和H．323协议分析了它们到呼叫处理模型适配的兼容性；针对SIP协议、H．323协议和H．248协议设计它们到连接控制模型的适配方案。基于上面分析的SIP到呼叫处理模型和连接控制模型的适配方案。设计和实现了同时具有呼叫处理和连接控制功能的MCU的控制模块。
第四章总结和展望，总结了本文的研究工作，展望了下一步可以进行的工作。
It is true that H.323 network, SIP network and soft-switch network will be long-standing all together. Therefore, it is most important challenge in communication research domain that complete inter-working between all together those multi-protocol communication networks is solved to the core. It is Next Generation Network (NGN) that can be based on to solve this inter-working problem. As well as NGN's layered framework, it is unforced that the research of compatibility of Multi-protocol communication networks will be carried through layer- independently. Using the function of lower layers, the service layer implements its service logic. Its processes is mainly made up of as follows: first, address resolving and routing, second, transforming between one protocol's message and another protocol's all together, third, compatibility of call model and protocol's messages. In the case of multi-protocol communication networks, without question, the processes are more complex than one-protocol communication network's
.
This paper is made up of for chapters:
The first chapter briefly introduces background and context of inter-working between next generation network and tradition network and this paper's frame.
The second chapter research the compatibility of multi-protocol communication networks on address resolving and routing based on NGN. Using TRIP, this paper design and implement the inter-working projects between H.323 network and SIP network. This paper also provides protocol middle-ware that can be used to complete transforming H.323's messages and SIP 's messages all together.
The third chapter is mainly concerned with compatibility of call model and protocol's messages. The call model reflects the communication properties in terms of a call-processing facet and a connectivity facet. The call-processing facet uses a basic call state model (BCSM) and the connectivity facet uses a set of call segment connection view (CSCV) states. The paper analyses the compatibility of between BCSM and H.323, SIP protocol. This paper designs the mappings of SIP, H.323 and H.248 to CSCV model. Lastly, this paper design and implement the MCU 's control module.
The fourth chapter sum up the whole paper and presents issues for further study.
