Method of updating a set of candidate frequency channels during wireless communications between a radio port and a mobile communications device

摘要

In a method of updating a set of candidate frequency channels during wireless communications between a radio port and a mobile communications device, the communications device switches to a current measured one of multiple pre-stored frequency channels not in a current set of candidate frequency channels to measure signal quality after an assigned time slot of a current time frame of a second time sequence, and switches back to a current working frequency channel prior to the assigned time slot of a succeeding time frame of a first time sequence. The mobile communications device updates a current set of the candidate frequency channels with the current measured frequency channel when the signal quality attributed to the current measured frequency channel is better than those attributed to the current set of the candidate frequency channels.
