An effective AAL1 architecture for N/spl times/64 structured services suitable to adapt DECT traffic to B-ISDN network

Data traffic originating at mobile infrastructures, such as utilised by DECT mobiles, is, in principle, constant bit rate traffic (CBR). On the other hand, the flexibility of the B-ISDN network to transport data at constant, variable (variable bit rate) or available (available bit rate) bit rates makes it ideal to be utilised as the communication medium among distributed mobile terminals residing at distant wireless networks. This paper proposes an architecture and a set of procedures suitable for use in UMTS-ATM specific platform realisations. The deployed architecture is also enhanced to support all AAL1 functions required for every possible envisaged type of mobile data transport service. It also takes into account all mobile data management requirements necessary for maintaining timing, buffering and delay variations requirements.
