摘　　要：针对特种通信边缘网络环境弱连接、高机动、传统业务触发机制处理复杂、呼叫时延大等问题,提出轻量化业务触发技术(RSCIM),通过扩展SIP消息头域,路由携带用户iFC触发AS列表信息,实现在多个排队业务AS节点间直接进行业务触发,避免通过S-CSCF来回触发业务,减少了众多AS与S-CSCF来回触发的信令开销,从而减少了IMS业务触发时延,提升业务切换速度,满足高机动通信场景需求。Aiming at the problems of weak connection and high mobility in special communication edge network environments,complex handling of traditional AS triggering mechanisms,and large call time delay,a lightweight AS triggering technology(RSCIM)is proposed.By expanding the SIP message header domain and carrying user iFC triggered AS list information through routing,direct AS triggering is achieved between multiple queuing business AS nodes,avoiding the need for S-CSCF to trigger AS back and forth,reducing the signaling overhead of many AS and S-CSCF to trigger back and forth,thereby reducing the IMS AS triggering delay,improving AS switching speed,and meeting the requirements of high mobility communication scenarios.
