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.

1. A method of operating a Session Initiation Protocol (SIP) server including a signaling data system and a session data system stored on a storage system and executed by a processing system, the method comprising:
in the signaling data system, receiving a first SIP message having a Session Description Protocol (SDP) data set, and in response, storing the SDP data set in association with a session segment identifier and transferring a session request having the session segment identifier and not the SDP data set; in the session data system, receiving the session request having the session segment identifier and not the SDP data set, and in response, authorizing the session request and transferring a session instruction having the session segment identifier; and in the signaling data system, receiving the session instruction having the session segment identifier, and in response, identifying the SDP data set with the session segment identifier and transferring a second SIP message having the SDP data set.
