ABSTRACT:
A method and system for providing extension phone service within a mobile radio communication system. The mobile radio communication system includes a home location register (HLR), a plurality of mobile switching centers (MSCs), and a plurality of mobile stations. A single subscriber number is assigned to each one of the plurality of mobile stations. When a call is directed to the single subscriber number, the HLR transmits an individual routing request message to each one of the plurality of MSCs where mobile stations assigned to the single subscriber number are believed to be located. Each of the MSCs pages the mobile stations within its service area. Upon receiving a response from one or more of the paged mobile stations, each of the MSCs establishes voice channels with the responding mobile stations, and alerts the stations' subscribers. The MSCs then report to the HLR which of the alerted subscribers answered the alert. The HLR then selects one of the mobile stations, routes the call to the selected station, and releases the remaining answering mobile stations.
