摘要
NGN(下一代通信网络Next Generation Network)以软交换为核心技术,通过开放的接口规范,具有实现与传统网络互连互通、通用移动性,融合固定与移动网络业务等特征。介绍了NGN的特点及其主要协议:呼叫控制协议、传输控制协议、媒体控制协议、业务应用协议、维护管理协议等。分析与比较了NGN接入层的不同接入方法,给出了无线局域网用户接入NGN的具体实现方法。
Next Generation Network can realize intercommunication with traditional network by using the technology of softswitch as its core technology. NGN has the open interface specification so that it can achieve fixed mobile convergence. Characteristics and main protocols of NGN are described. Different access method in access layer of NGN is analyzed and compared. It gives a specific realization method for access of NGNby wireless local area network users.
