<p>A multi-slot TDMA communications system, such as DECT, has provision for allocating full time slots and double time slots to calls. However, whereas full time slot calls are normally assigned to what a subscriber unit or base station has determined as the best time slot, a double time slot call is constrained by having to start with an even numbered time slot in a frame. This can lead to an inferior grade of service for double time slot calls because during call set up, although there may be free full time slots, they are not always arranged as pairs with the first time slot being even numbered. A modified slot selection algorithm is proposed in which whenever possible a full time slot call is assigned to an acceptable inactive time slot located adjacent to an active full time slot in a frame, even though this may mean that it is not the best inactive time slot.</p> |
