Abstract
Within a wireless CDMA communication system (,), at least one dedicated inbound code (,) and at least one dedicated outbound code (,) are provided solely for use in providing group calls. Based on a dedicated inbound code, a subscriber unit transmits a group call signal (,) and a base transceiver system receives the group call signal (,). In turn, the base transceiver system retransmits the group call signal based on a dedicated outbound code (,). Alternatively, or in addition, the base transceiver system sends the group call signal, along with information regarding the dedicated inbound code, to a controller (,). Subscriber units can receive group code updates (,) indicating the particular dedicated inbound and outbound codes to be used within a given site. In this manner, the communication system can provide group call functionality in a public system.
