The 3rd-Generation Partnership Project (3GPP) has selected Session
Initiation Protocol (SIP) as the session establishment protocol for
the 3GPP IP Multimedia Core Network Subsystem (IMS).  IMS is part of
Release 5 of the 3GPP specifications.  Although SIP is a protocol that
fulfills most of the requirements for establishing a session in an IP
network, SIP has never been evaluated against the specific 3GPP
requirements for operation in a cellular network.  In this document,
we express the requirements identified by 3GPP to support SIP for
Release 5 of the 3GPP IMS in cellular networks.

This document is a product of the Session Initiation Proposal
Investigation Working Group of the IETF.
