ABSTRACT:
A radio telephone communication system is provided for communicating with radio telephones associated with a radio telephone system when the radio telephones are operating in a remote geographical area served by another radio telephone system. The radio telephone user transmits by telephone a signal which causes an activation signal to be entered into the data base of a computer associated with the home system. This activation signal identifies the radio telephone and the remote radio telephone system covering the area in which the radio telephone will be located temporarily. Upon receipt of a telephone call for the radio telephone, the data base is searched for the activation signal, and the call is directed to the remote system through a land line telephone connection to the roamer access port of the remote system. The telephone call then is completed through radio communication between the remote system and the radio telephone.
