Description

ABSTRACT:
A system and method for providing subscriber presence information in a dispatch network is disclosed. In an embodiment of the method, presence subscription information related to a dispatch network subscriber is provided to a home location register. A presence message is provided to a presence server related to the subscription information. A presence status is provided to a party by the presence server. In an embodiment of the system, a home location register stores a subscriber presence table. The presence table includes presence subscription information related to a dispatch network subscriber. A dispatch application processor (DAP) is coupled to the home location register and the DAP retrieves the presence subscription information for a subscriber registered in the DAP. The DAP provides a presence message to the presence server and the presence server provides a presence status to a communications medium.
