Patent ID: 7321765

Claim:
A timing method for a mobile station in a wireless communication system, the mobile station comprising a lower layer and an upper layer, the timing method comprising: generating at least a first buffering area in the mobile station for storing a value representing a number of occurrences of a periodic event; receiving a first action with the upper layer from the lower layer, the first action occurring at a first periodic interval; updating the value stored in the first buffering area with the upper layer after receiving the first action; utilizing the first periodic interval of the first action executed by the lower layer of the mobile station to derive a timing unit; comparing the value stored in the first buffering area with a first predetermined value; and when the value stored in the first buffering area reaches the first predetermined value, utilizing the compared or the predetermined value and a timing unit as a time basis for performing a second action with the lower layer to monitor a neighboring cell in the wireless communication system; wherein the second action occurs at a second periodic interval greater than the first periodic interval.
