In the third generation cellular networks and beyond, a wide variety of different services are/will be provided by the operators. Out of QoS reasons, it is preferable to assign higher priority to certain connection types. These include calls carrying

In cellular networks, a higher priority can, out of Quality of Service reasons, be given to ongoing connections than new call attempts. This can be achieved by having capacity in each cell (guard channels) exclusively reserved for arriving handover c

We consider a high speed ATM bus, which can serve a small number of stations (≤16). The bus is slotted and each slot is long enough to contain one ATM cell. Transmission on the bus is controlled by an arbitrator. Each station sends its status infor
