摘　　要：目前,会话初始化协议(Session Initiation Protocol,SIP)被广泛应用于各种音视频业务系统中,由于SIP体制具有易集成、成本低廉、使用方法灵活等特点,再加上信息通信技术(Information Communication Technology,ICT)融合的趋势越来越明显,已在移动、电信运营商的4G、5G移动通信中得到广泛应用,目前也正在向以战场通信网为代表的其他特殊领域进行应用。但是在战场通信网中,接入机制具有泛在性和随遇性,位置管理机制需要具有容灾性和抗毁性,这为SIP体制的应用带来了巨大的挑战,迫切需要对SIP业务控制方法专门进行适应性研究和设计,以满足战场通信网的应用需求。通过深入分析SIP体制的接入机制、位置管理机制以及呼叫寻址机制,提出两种SIP业务控制增强方法,并给出了各自适合的应用场景,最后进行了试验验证,证明了两种方案各自的优势,为SIP体制应用于战场通信网提供了理论支撑。At present,SIP(Session Initiation Protocol)is widely used in various audio and video service systems.Due to the characteristics of SIP system such as easy integration,low cost and flexible use method,coupled with the increasingly obvious trend of its convergence with ICT(Information and Communication Technology),and has been widely used in 4G and 5G mobile communications of China Mobile and China Telecom,and now is being applied to other special fields represented by battlefield communication networks.However,in the battlefield communication networks,the access mechanism is ubiquitous and random,and the position management needs to be disaster-tolerant and invulnerable,which brings great challenges to the application of the SIP system,and there is an urgent need for the SIP service control method to be specially adapted to the research and design to meet the application requirements of the battlefield communication networks.Through in-depth analysis of the access mechanism,position management mechanism and call addressing mechanism of SIP system,this paper proposes two SIP service control enhancement methods and gives their respective suitable application scenarios,and finally carries out experimental validation,proving the advantages of each of the two methods,and providing theoretical support for the application of SIP system to the battlefield communication networks.
