Providing UMTS services in a wireless ATM LAN

In this paper, we will be concerned with a wireless wideband ATM LAN (WWLAN) interconnected via a broadband link to an ATM/B-ISDN fixed network. The aim of this work is twofold: (i) the definition of the WWLAN protocol architecture and of the interworking functions with the fixed ATM/B-ISDN; (ii) the mapping of the UMTS paradigm into the WWLAN scenario. The work is mainly focused on the control plane and on the interactions between WWLAN and B-ISDN for the provision of UMTS services.
