The interconnection of third generation mobile systems (UMTS) with fixed and wireless access networks over V/sub B5.2/ interface

This paper proposes the V/sub B5.2/ interface as a basis for the definition of the generic Iu interface. The architecture of the emerging network that incorporates a third generation mobile system (UMTS) service node (SN), and any kind of access network (AN) technology, fixed or wireless, over the proposed V/sub B5.2/ oriented generic interface, is presented. The mapping of the call/connection control (CC) related messages, needed for the manipulation of connections, with the involvement of the broadband bearer connection control protocol (B-BCCP), is formed in a generic approach. The paper concludes pointing out possible enhancements to the existing V/sub B5.2/ interface, and mainly to the B-BCCP, in order to play effectively the role as a candidate of the Iu generic interface.
