In a wireless code-division multiple access (CDMA) system (), a talkgroup () of subscriber units is provided. A sub-talkgroup () of subscriber units, forming a part of the talkgroup is assigned at least one inbound channel (). The talkgroup is assigned outbound channels (). Members of the sub-talkgroup may simultaneously transmit voice information () using the at least one inbound channel, which voice information is summed () and re-transmitted to the talkgroup using the outbound channels. Voice information is summed so that an individual talker receives summed voice information without the individual subscriber's voice content. Subscriber units in the sub-listengroup are allowed to transmit voice information only after requesting, and receiving, an additional inbound channel.

Method and apparatus for a talkgroup call in a wireless communication system

The method for reducing status reporting in a wireless communication system (100), such as a code division multiple access wireless communication system is described. Wireless communication system (100) includes a mobile switching center (202), a base station controller (204), and a plurality of base transceiver stations (240-242). The method includes wireless communication system (100) receiving a mobile communication signal (115) from a mobile station (220), and based on the mobile communication signal (115), invoking delivery of an information element (230) to base station controller (204). The method further includes, based on information element (230), selectively forwarding by base station controller (204) a status message to mobile switching center (202). In addition, the method includes acknowledging, by base station controller (204), successful receipt of information element (230).
