Abstract
Several embodiments of an IMS communications network are disclosed. In one embodiment, the network comprises a plurality of dispatch application servers (DAS), an S-CSCF, and an event notification server. The S-CSCF is adapted to receive an IMS registration request from a dispatch client, authenticate the registration request, send a registration confirmation to the dispatch client, and send a notification indicating the registration of the dispatch client to an event notification server. The event notification server is adapted to receive the notification from the S-CSCF, select a DAS, and send a notification to the selected DAS indicating an assignment to provide dispatch service to the dispatch client. In another embodiment, the registration notification to the event notification server is sent from the dispatch client, instead of the S-CSCF.
