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.
