CALL ADMISSION CONTROL FOR MULTISERVICE PACKET-SWITCHED CELLULAR MOBILE RADIO SYSTEMS

Next generation personal communication systems will provide a range of different services to moving users. In parallel, packet switching is being proposed as a way to statistical multiplexing and hence to bette r resource exploitation. The co-existence of different services may pr ove difficult due to the different requirements on quality of service parameters like packet loss, delay, and so on. This requires a careful design of Call Admission Control policies, which are to be quite diff erent from those used in fixed network, due to two phenomena which are typical of mobile systems, namely co-channel interference and handove rs. In this paper we address these complex topics, and propose some ba sic rules for Call Admission Control policies suitable in this context .
