Abstract
An off-load cellular system controls cellular service between a main cellular system and the off-load cellular system and provides off-load cellular service to a mobile telephone. The off-load cellular system includes a receiver circuit, monitoring and receiving an origination message broadcast from the mobile telephone located in the off-load cellular system, and a system controller, for receiving the origination message output from the receiver circuit, and for outputting a connect signal indicating whether the off-load cellular service is to be provided to the mobile telephone responsive to the origination message. In addition, the off-load cellular system includes a connection controller for receiving the connect signal output from the system controller, for transmitting to the mobile telephone a voice connect message indicating a frequency to obtain the off-load cellular service responsive to the connect signal, and for connecting the mobile telephone with a calling party, providing the off-load cellular service to the mobile telephone.
