scope:

The present stage 3 specification defines the Diameter based implementation for bootstrapping Zh interface (HSF-HSS) and Dz interface (BSF-SLF) for HSS resolution for the BSF, and GAA Application Zn interface 9BSF-NAF) in Generic Authentication Architecture (GAA). The definition contains procedures, message contents and coding. The procedures for bootstrapping and usage of bootstrapped security association are defined in 3GPP TS 33.220 [5].

This specification is a part of the Generic Authentication Architecture (GAA) specification series. The Third Generation Partnership Project (3GPP) has developed the specification in a form optimized for the wireless environment. This Recommendation reference the ETSI version of the 3GPP specification and specifies only the modification necessary to optimize it for the cable environment. Additions are shown in blue underline and deletions in It is an important objective of this work that interoperability between IPCablecom 2.0 and 3GPP IMS is provided. IPCalecom 2.0 is based upon 3GPP IMS, but includes additional functionality necessary to meet other requirements of cable operators. Recognizing developing converged solutions for wireless, wireline, and cable, it is expected that further development of IPCablecom 2.0 will continue to monitor and contribute to IMS developments in 3GPP, with the aim of alignment of 3GPP IMS and IPCablecom 2.0.

The modifications to ETSI TS 23-008 V6.8.0 (2005-12) Internet Protocol (IP) multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP); Stage 3 are listed below.
