    摘要： A repeater receives an indication that a subscriber unit is initiating a call session on a channel, and indicates that the channel is busy. The repeater repeats a transmission from the subscriber unit and sets a timer for a first time upon determination that the transmission has ended. The timer is set for a second time if a new transmission is not received from a subscriber unit that is allowed to transmit on the channel prior to the expiration of the first time; otherwise, the repeater accepts a new transmission from a subscriber unit that is allowed to transmit on the channel if the new transmission is received prior to an expiration of the second time. Upon receipt of each new transmission received prior to the expiration of the second time, the repeater clears the timer, repeats the transmission on the channel, and resets the timer for the first time upon determination that the transmission has ended.

    摘要翻译： 中继器接收到用户单元在信道上发起呼叫会话并指示频道正忙的指示。 中继器重复来自用户单元的传输，并且在确定传输已经结束时首次设置定时器。 如果在第一次到期之前没有从允许在信道上发送的用户单元接收到新的传输，则定时器被设置为第二次; 否则，如果在第二次到期之前接收到新传输，则中继器接受来自用户单元的新传输，该新传输被允许在信道上进行发送。 在接收到在第二次到期之前接收到的每个新传输之后，中继器清除定时器，重复该信道上的传输，并且在确定传输已经结束之后，首次重置定时器。

    摘要： In a two-way radio frequency (RF) communications system having at least one repeater, a plurality of channels, and a plurality of subscriber units, a repeater hosts a first channel that is currently serving as a rest channel. The channel that is currently serving as the rest channel is monitored by subscriber units that are idle in the system. When the repeater determines to select a second channel to serve as the rest channel, it determines whether there is at least one eligible channel to serve as the rest channel. If there is at least one eligible channel in the system, the repeater may select the second channel to serve as the rest channel from one of the eligible channels.
