摘要
针对煤矿井下语音通信对调度功能的特定要求,分析了VoIP语音通信软交换技术,提出了在软交换平台中实现矿用调度通信业务的方法,并介绍了一种采用FreeSWITCH开发的基于软交换平台的矿用调度通信业务系统的设计方案。该系统可提供呼叫、监听、插话、夺话、强拆、组呼、单听、听说、添加/删除临时成员、设置/取消主席、录音等调度通信业务功能,可扩展性强,并可根据井下用户数量选择服务器硬件。测试结果验证了该系统的可行性,为煤矿井下调度通信业务平台提供了一种实用方案。
In view of special requirements of dispatching functions of voice communication in coal mine underground, the paper analyzed soft switch technique for VoIP communication, proposed an implementing method of mine-used dispatching and communication service in soft switch platform, and introduced a design scheme of mine-used service system of dispatching and communication based on soft switch platform by use of FreeSWITCH. The system provides dispatching and communication services such as calling, monitoring, interjecting, contesting calling, forcedly demolishing calling, group calling, listening only, listening and speaking, adding/deleting provisional members, setting/canceling chairman, recording and so on with high expansibility, and can select hardwares of server according to number of users underground. The testing result verified validity of the system, which provides a practical scheme for dispatching and communication service platform in coal mine underground.
