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).

Claims

1. A method of operating a multi-camp mobile communication device, comprising:

establishing an interconnect call with a first communication system at a first modem of the mobile communication device;

during the interconnect call;

receiving an incoming dispatch call over a dispatch circuit of a second communication system at a second modem of the mobile communication device, the dispatch call initiated by a dispatch calling party;

responding automatically to the dispatch call, without action from a user of the multi-camp mobile communication device, with a pre-recorded message stored in the mobile communication device indicating that the user of the mobile communication device is currently busy.

2. A method of operating a multi-camp mobile communication device as defined in claim 1, further comprising retaining a dispatch identifier of the dispatch calling party.

3. A method of operating a multi-camp mobile communication device as defined in claim 1, further comprising:

subsequent to responding to the dispatch call, receiving a message from the dispatch calling party over the dispatch circuit; and

storing the message in the multi-camp mobile communication device.

4. A method of operating a multi-camp mobile communication device as defined in claim 1, wherein the interconnect call is performed using a code division multiple access air interface.

5. A method of operating a multi-camp mobile communication device as defined in claim 3, further comprising alerting a user of the multi-camp mobile communication device that the message has been stored.

6. A method of operating a multi-camp mobile communication device as defined in claim 5, wherein the alerting is performed by at least one of an audio alert and a visual alert.

7. A multi-camp mobile communication device, comprising:

a first modem for connecting to a first communication network;

a second modem for connecting to a second communication system; and

a controller for controlling operation of the first and second modems;

wherein, when the first modem is engaged in a call with the first communication system and the second modem receives a dispatch call from a dispatch calling party over the second communication system, the controller responds to the dispatch call by transmitting a message to the dispatch calling party.

8. A multi-camp mobile communication device as defined in claim 7, wherein upon receiving the dispatch call, the multi-camp mobile communication device retains a dispatch identifier of the dispatch calling party in a memory

9. A multi-camp mobile communication device as defined in claim 7, wherein, subsequent to responding to the dispatch call, the multi-camp mobile communication device receives a message from the dispatch calling party over the dispatch circuit, and stores the message in a memory of the multi-camp mobile communication device.

10. A multi-camp mobile communication device as defined in claim 7, wherein the first modem is a code division multiple access modem.

11. A multi-camp mobile communication device as defined in claim 9, further comprising a user interface for alerting a user of the multi-camp mobile communication device that the message has been stored.

12. A multi-camp mobile communication device as defined in claim 11, wherein the user interface includes at least on of an audio alert element and a visual alert element.
