Ancillary data support in session initiation protocol (SIP) messaging |
摘要 |
A SIP ancillary data server provides host to auxiliary data for an emergency SIP session (call) uniquely referred to in a transported SIP header. In a manner similar to how location is represented in an emergency call, a SIP header is extended. The extended SIP Header contains one of two possible types of content elements: either (a) a content pointer element to a SIP Message body part (a “cid:”, or content identifier); or (b) an <information_URI> (a.k.a, “info_URI” in this document).
