ABSTRACT:
A mobile communications system accommodating both expanded spectrum (ES) mobiles and non-expanded spectrum (NES) mobiles incorporates a first set of (ES) channels and a second set of (NES) channels. A proportion of the channel requests from ES mobiles are allocated to a queue for NES channels. NES channels are allocated to these ES mobiles until no further NES resources are available. Further requests from ES mobiles in the NES channel queue are then met by allocating available ES channels. This provides an enhanced efficiency of utilisation of channel resources. Advantageously, a subset of NES channels is reserved for preferential use by NES mobiles to ensure fair allocation of channels between the two types of user, these channels being allocated to ES mobiles only if no other channels are currently available.
