Abstract: A communication unit (118) provides service information related to a second communication service to a base site (114) that provides a first communication service to the communication unit (118). The base site (114) receives the service information, stores the service information, and receives a service request for the communication unit (118) to participate in the second communication service. Finally, the base site (114) transmits a control message to the communication unit (118), via a control communication resource, to alert the communication unit (118) as to requested participation in the second communication service.

Abstract: Responsive to a received call request, a resource controller (105) assigns a first control channel to the call request (302). When there are no traffic channels available and there is at least one pending call request (303-304), it is determined whether there is a second control channel, combinable with the first control channel, available from a group of un-assigned control channels (305). Alternatively, it is determined whether the second control channel is available from a group of assigned control channels (308). The second control channel, when available, is assigned along with the first control channel as an additional traffic to one of the pending call requests (307).
