Abstract:
1. A method for mapping a Universal Fleet Member Identifier (UFMI) to a previously assigned UFMI, comprising the steps of: receiving an Integrated Digital Enhanced Network (iDEN) routing request message from a dispatch application processor (DAP) associated with a calling party at a serving home location register (HLR) of a called party, wherein the routing request message includes a first UFMI associated with the called party; obtaining a second UFMI of the called party by the HLR by consulting a subscriber table stored in the HLR; transmitting an iDEN routing response message to the DAP by the HLR, wherein the routing response message includes the second UFMI associated with the called party; determining a second HLR associated with the called party by the DAP by using the second UFMI, wherein the second HLR is associated with a gateway from an iDEN network; transmitting a second iDEN routing request message from the DAP to the gateway, wherein the second routing request message includes the second UFMI; and transmitting a second iDEN routing response message to the DAP by the gateway.
