摘　　要：信令是通信网的神经系统,是交换机的主要组成软件。局间信令是运行在交换节点之间的控制面信息,它主要实现节点间连接的建立、释放以及中继资源的管理等功能。在介绍信令技术基本原理的基础上,简要介绍了信令技术发展的几个阶段,指出了各阶段的典型信令方式以及其优缺点。根据通信网网络特点和实际需求,设计了一种局间信令实现方案,满足了网内话音业务的需求。对方案中各软件模块的功能进行了详细描述及分析,给出了软件开发环境,对理解、开发信令系统具有参考价值。Signaling is the nerve of a communication network,forming the main part of the switching software. As the controlling in- formation exchanged between nodes, trunk signaling provides connection establishment, release, and resource management functions. The basic principle of the signaling technology is introduced. The development stages and their typical signaling modes, advantages and disadvantages are presented. According to the features and practical requirements of the private network,a software solution of the trunk signaling which can meet the voice service requirement of the private network is given. The function of each software module is described and analyzed. The software development environment is given. It provides reference for understanding and development of the signaling system.
