Lightweight triggering technology for edge network services
Aiming at the problems of weak connection and high mobility in special communication edge network environ-ments,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 trig-gering delay,improving AS switching speed,and meeting the requirements of high mobility communication scenarios.
