ABSTRACT:
Automatic activation of a wireless device with a first wireless communication system occurs within an area having an overlapping second wireless communication system. Operation of the first communication system access procedure is achieved by masking an access and authentication process for the second communication system from interference from the control signal levels of the second wireless communication system. During the first time access, the first communication system is supplied with the SID and MIN and ESN numbers for authentication and access.
