该系统在煤矿井下架设分层的基于IP技术的无线网络,该系统具有简单、成本低和可扩展性强等特点。同时借鉴SIP协议,设计了一个语音通信信令协议,满足无线通信系统的要求。
The system is based on a layered IP-based wireless network in a coal mine. The system is characterized by its simplicity, low cost and scalability. At the same time, SIP protocol is used to design a voice communication signaling protocol to meet the requirements of wireless communication system.
