  • Method and device for group call initiation
    Patent number: 8396501
    Abstract: Upon a user's command, a communication device accesses a call list having a plurality identifiers and receives a user's selection of a talkgroup identifier from the call list. The communication device switches to a first channel associated with the selected talkgroup identifier to allow a call on the first channel. When the call ends, the communication device sets a first timer and monitors the first channel for voice activity, and if voice activity is detected, continues the call on the first channel. When the first timer expires and no voice activity is detected, the communication device sets a second timer and scans a home channel for voice activity; and if no voice activity is detected, the communication device continues to monitor the first channel until the second timer expires or voice activity is detected on the home channel, then it automatically switches to the home channel.
