Abstract: A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.

Abstract: A method (600) for prioritizing communication services across multiple service initiators in a multi-modal communication device (110). The method can include establishing an inter-process communications link (140) between a first processor (125) and at least a second processor (130) within the communication device. Responsive to a request (202) for a first service provided by the first processor, a determination can be made whether the first service has a higher priority than a second service currently active on a second processor. A conflict message can be provided in response to the second service having a higher priority than the first service, or at least one process, such as initiation of the first service, can be implemented in response to the first service having a higher priority than the second service. Further service initiated messages (204, 206) can be communicated from the second process to an external device and to the first processor.
