Abstract

An inter-working network facilitating PTT communications among roaming subscribers spanning a plurality of disparate dispatch networks includes a signaling controller, a media gateway, a system for facilitating the monetization of inter-carrier dispatch communications and a group management server. The signaling controller and media gateway generate dispatch call records for dispatch sessions facilitated through the inter-working network. The system includes a billing accumulator and a settlement entity. The billing accumulator is interfaced with the inter-working network and includes logic to receive and store the dispatch call data records from the inter-working architecture. The settlement entity is interfaced with the billing accumulator, and includes settlement logic for converting each stored dispatch call data record to a billing record for each of at least two of the dispatch networks. The group management server is interfaced with group management servers in each of the dispatch networks.
