宽带集群调度台SIP服务器及心跳机制设计

摘要

Considering the limited capability and dispatching functions of multi-seat and grading dispatching, combining B/S structure of dispatching station in broadband trunking, a SIP(Session Initiation Protocol) server is researched in-depth and devised;in the meantime, a new heartbeat mechanism in SIP server session is proposed. Experimental result indicates that the SIP server meets the requirements of dispatching station. Moreover, the flexibility and reliability of SIP server are verified in signal processing and resource control services.%针对传统调度台多席位和分级指挥调度能力有限、调度功能单一等问题，结合B/S结构宽带集群调度台结构，重点研究并设计了一种调度台SIP服务器，同时给出了一种SIP服务器会话过程心跳检测机制。实验测试结果表明，此调度台SIP服务器设计满足宽带集群系统指挥调度需求，在信令处理和服务资源控制方面具备灵活性与可靠性等优点。
