Abstract
An auto answer cellular phone system is described in which the caller ID field of an originating cellular page message is modified to be a group ID number designating a plurality of cellular phones within a group. In an example embodiment, an originating phone dials a group phone number, the group phone number is routed to a group ID server by the mobile radio switch. The group ID server looks up the group number in a lookup-table to determine which cellular phones are included in the particular group and then forwards the individual group members ID codes to the switch for connection to the originating phone. Before sending the group members' ID codes to the switch, the group ID server 21 replaces the caller ID field from the originating phone ID to the group number ID. This tells the mobile stations that the call is a group call, as opposed to an individual call and forces the mobile stations into an auto-answer mode such that the mobile station then acts as a dispatch radio, as opposed to a human-answer cellular phone.
