Session initiation protocol (SIP) server to efficiently handle session description protocol (SDP) data sets

摘要

A Session Initiation Protocol (SIP) server comprises a signaling data system that receives a first SIP message having a Session Description Protocol (SDP) data set. The signaling system responsively stores the SDP data set in association with a session segment identifier and transfers a session request having the session segment identifier and not the SDP data set. The SIP server has a session data system that receives the session request having the session segment identifier and not the SDP data set. The session data system responsively authorizes the session request and transfers a session instruction having the session segment identifier. The signaling data system receives the session instruction having the session segment identifier and responsively identifies the SDP data set with the session segment identifier and transfers a second SIP message having the SDP data set.
