Method and apparatus for alerting a communication unit of a service request in a communication system

摘要

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.
