Abstract: A multi-camp mobile communication device (100) includes a first radio modem (102) and a second radio modem (104). Each modem is designed to communicate with a respective communication system (110, 112). Upon engaging in an interconnect call (204) over the first modem with the first communication system, the multi-camp mobile communication device receives a dispatch call at the second modem (206) from the second communication system. The multi-camp mobile communication device replies to the dispatch call with a pre-recorded message (208). The dispatch calling party may respond to the pre-recorded message with a voice message that is recorded by the multi-camp mobile communication device (210, 212).

Abstract: A device and method for receiving communications associated with a second communication service while actively communicating using a first communication service is disclosed. The method includes receiving an incoming call associated with a second communication service at a wireless device (104). The second communication service is either different than the first communication service currently being used by the wireless device (104) or is a similar communication service using a different network than the first communication service. The method also includes notifying a user of the wireless device (104) of the incoming call associated with the second communication service.

Abstract: A system (20) of targeted broadcasting in a cellular communication system during an event can include at least one mobile unit (25) having stored therein scheduling information relating to an event, a designated location for the event, and a designated group channel for monitoring such event. The mobile unit can further be programmed to monitor (67) for the event in a designated location and on a designated group channel during a predetermined time window and receive (71) a targeted message during the event on the designated group channel if a current location of the mobile unit matches the designated location stored. The mobile unit can be programmed to transmit at least one group call message response in response to receiving the group call message only when the mobile unit is in the designated location. The system can further include fixed network equipment (26) that transmits data related to the event.
