1. A CDMA communication system, comprising:
- a CDMA network having a mobile switching center connected to a public telephone switching network, operable to provide voice and data call services to mobile communication devices;
a packet data system coupled to said CDMA network to provide packet data services to the mobile communication devices; and
a trunking system coupled to said CDMA network and a packet data network to provide group call services to the mobile communication devices via the packet data network, said trunking system comprising (1) a plurality of dispatching clients in communication with said CDMA network to transmit data packets of a group call to and from mobile communication devices of a trunking group where members of each trunking group share a common trunking data link for transmission of data packets, and (2) a dispatching server connected to said packet data network and in communication with said dispatching clients to process group calls.

9. A method for providing group call services in a CDMA communication system, the method comprising:
-
providing a plurality of dispatching clients in a CDMA system to dispatch group call requests via a packet data network to a dispatching server that controls and manages group calls; using a common trunking message link through the packet data network to transmit trunking messages between a dispatching client and the dispatching server; and using a single trunking data link to each trunking group between the dispatching server and each dispatching client such that a plurality of group members share the single trunking data link in transmitting user data over the packet data network. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
