Abstract: A radio receives audio information on a first traffic channel in a radio frequency (RF) site. The radio receives, on the first traffic channel, an announcement of alternative traffic channels on which the audio information is also transmitted in adjacent RF sites. The radio determines signal strength indicators for the alternative traffic channels in the adjacent RF sites while continuing to receive the audio information on the first traffic channel. The radio determines that a signal strength associated with the first traffic channel is below a first threshold. Based on the determination and as a function of the scanning, the radio roams to a second traffic channel, selected from the alternative traffic channels, in an adjacent RF site where a signal strength associated with the second traffic channel is above a second threshold. The radio receives the audio information via the second traffic channel.

Abstract translation: 无线电接收机在射频（RF）站点的第一业务信道上接收音频信息。 无线电接收机在第一业务信道上接收在相邻RF站点上发送音频信息的备选业务信道的通告。 无线电装置确定相邻RF站点中替代业务信道的信号强度指示符，同时继续在第一业务信道上接收音频信息。 无线电确定与第一业务信道相关联的信号强度低于第一阈值。 基于扫描的确定和功能，无线电漫游到相邻RF站点中从替代业务信道中选择的第二业务信道，其中与第二业务信道相关联的信号强度高于第二阈值。 无线电通过第二业务信道接收音频信息。
