Abstract: A method and system for priority handling of a dispatch call in a dispatch network is disclosed. A dispatch call request message from a mobile communications unit is received at a dispatch cell site. The cell site determines whether a DAP is configured for operation in a call request reject mode. The cell site determines a priority level of the mobile communications unit if the DAP is configured in the call request reject mode. When the priority level meets a defined threshold, the cell site forwards the dispatch call request message to the DAP and the DAP processes the dispatch call request message.

Abstract: A system and method for operating a user functionality in a mobile communications device is disclosed. In an embodiment of the system, a communications infrastructure provides interoperability between a first communications network utilizing a first technology and a second communications network utilizing a second technology. The infrastructure provides an indicator to a mobile communications device in communication with the first communications network to either activate the user functionality or deactivate the user functionality. In accordance with an embodiment of a method of the present invention, the method includes providing the indicator to the mobile communications device in communication with the first communications network utilizing the first technology by the communications infrastructure. The user functionality is activated if the indicator is provided in a first state and the user functionality deactivated if the indicator is provided in a second state.

Abstract: A system and method for providing an user the ability to roam onto a peer Integrated Digital Enhanced Network (iDEN) Network. An iGW supports the passing of Dispatch registration information back to the users home network. The iGW will also support and assist in setting up Dispatch Calls between the two iDEN Networks, and vice versa. Exemplary embodiments of the present invention also support roaming from another technology that supports Dispatch Services, where if a iDEN subscriber with a dual mode phone (i.e., iDEN & GSM), was to roam onto another carrier with a different technology but with Dispatch capabilities, the iDEN subscriber is able to register on the roaming carrier's network. The iGW is capable of receiving the registration update from the roaming network and updating the iDEN Network with the location of the iDEN Subscriber.

Abstract: An apparatus and method for mapping a newly assigned Universal Fleet Member Identifier (UFMI) to a previously assigned UFMI is disclosed. In an embodiment, an Integrated Digital Enhanced Network (iDEN) routing request message is received from a dispatch application processor (DAP) associated with a calling party at a serving home location register (HLR) of a called party. The routing request message includes a previously assigned UFMI of the called party. A newly assigned UFMI of the called party is obtained by the HLR by consulting a subscriber table stored in the HLR. An iDEN routing response message is transmitted to the DAP by the HLR, where the routing response message includes the newly assigned UFMI associated with the called party.

Abstract: A method and system for placing a dispatch call from an Integrated Digital Enhanced Network (iDEN) to a non-iDEN network is disclosed. An inter-urban call restriction check process is performed by an iDEN dispatch call processor if a response to a query indicates that a target dispatch call processor associated with a called entity is associated with the iDEN network and the inter-urban call restriction check process is not performed by the iDEN dispatch call processor if the response indicates that the target dispatch call processor is associated with the non-iDEN network.

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.
