Radio telecommunications network and method of supporting operation of a combined mobile telephone and pager

摘要

The present invention is a method within a radio telecommunications network for delivering a telephone call to a mobile station having a telephone portion, a pager portion, and a relay switch between the telephone portion and the pager portion. Data indicating that the mobile station is capable of receiving standard paging messages from a paging network is recorded in a home location register (HLR) associated with the mobile station. The method enables a subscriber to turn off the telephone portion to conserve battery power. When a call is received in a cellular network for the mobile station, and the mobile station cannot be contacted, the cellular network requests an associated paging network to send a page to the pager portion. The paging network is requested to page the pager portion of the mobile station via a datalink from the cellular network. The pager portion then activates the telephone portion through the relay switch, and the cellular network completes the call.
