EVOLUTIONARY MOBILITY AND SERVICE SUPPORT IN DECT ACCESS NETWORKS

This paper presents an access-independent network architecture for sup porting UMTS service capabilities Tile approach is based on an enhance d B-ISDN core network with personal and terminal mobility provided by intelligent network techniques. A physical realization is presented, a nd the protocols corresponding to the physical interfaces are identifi ed, Protocols are proposed for UMTS mobility and service support, and the impact on the B-UNI and IN interfaces is considered, Reflecting th e vision of tile ETSI global multimedia mobility (GMM) standardization framework, UMTS service support through non-UMTS access is considered , Consideration of DECT as a UMTS access technology leads to an interw orking proposal that presents each DECT terminal to the core network i n terms of UMTS functional entities, Access-independent usage of UMTS terminal applications motivates additional interworking in tile termin al to encapsulate the access network, The desirability of an access-in dependent UMTS application programming interface in the terminal is In dicated.
