Abstract: 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.

Abstract translation: 提供了一种以多观察模式操作无线电通信装置的方法。 无线电通信设备在主信道和至少一个非主信道上接收通信。 另外，话音通道能够响应主通道上接收的通信。 无线电通信设备确定是否响应于在非主信道上接收的通信而发送任何传输活动。 当在非主信道上接收到通信之后，当对于非主信道接收到的通信是否包含关键信息时，在不存在预定时间段的传输活动的情况下，进一步确定无线通信装置是否包括关键信息。 当无线电通信设备确定在主信道上接收到的通信包括关键信息时，无线电通信设备切换到对讲信道以响应在非主信道上接收的通信。
