ABSTRACT:
A mobile communication system permits a mobile terminal to operate in a microzone system which services a local area and to also operate in a cellular telephone system which is available in the local area. The microzone telephone system uses the same frequency band and channels of the cellular telephone system and includes a monitoring receiver which monitors the channels within that frequency band and makes those channels which are less likely to interfere with the cellular telephone system available to the microzone system. The microzone system includes a portable terminal which is capable of accessing the cellular system and, when in range of the microzone system, capable of accessing the microzone system on idle ones of the cellular channels which have been made available to the microzone system.
