Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) - Resource and Admission Control: H.248 Profile for controlling Border Gateway Functions (BGF) in the Resource and Admission Control Subsystem (RACS) - Protocol specification

The Working Item shall cover new NGN Release 2 requirements affecting the Ia profile as defined in the NGN vR2 RACS Stage 2 TISPAN-020xx. To that effect a new version 2 of the Ia profile will be started. Additionally the profile will be updated with any improvements that help clarify the usage within NGN Releae1. The Ia profile version 2 shall maintain backwards compatibility with version 1.
