METHOD FOR OPERATING A RADIO COMMUNICATION DEVICE IN A MULTI-WATCH MODE

摘要

A method for operating a radio communication device in a multi-watch mode is provided. The radio communication device receives communications on a primary channel and at least one non-primary channel. Further, a talk-back channel is enabled to respond to communications received on the primary channel. The radio communication device determines whether there is any transmission activity in response to a communication received on the non-primary channel. The radio communication device further determines whether the communication received on the non-primary channel comprises critical information when there is no transmission activity for a pre-defined time period since the communication was received on the non-primary channel. When the radio communication device determines that the communication received on the primary channel comprises critical information, the radio communication device switches to the talk-back channel to respond to communications received on the non-primary channel.

1. A method of operating a radio communication device, the method comprising:
operating the radio communication device to receive communications on a plurality of channels comprising a primary channel and a non-primary channel during a multi-watch mode of operation; enabling a talk-back channel to respond to communications received on the primary channel; determining whether there is any transmission activity in response to a communication received on the non-primary channel; determining whether the communication received on the non-primary channel comprises critical information when there is no transmission activity for a pre-defined time period since the communication was received on the non-primary channel; and switching to the talk-back channel to respond to communications received on the non-primary channel in response to determining that the communication received on the non-primary channel comprises critical information.
