Claim Text:
1. An in-synchronization and out-of-synchronization handling method, comprising; reporting an invalid frame indication to a high layer by using a physical layer, wherein the invalid frame indication is used to indicate an invalid frame, and the invalid frame is a frame not used for detecting out-of-synchronization; upon receiving, by the high layer, the invalid frame indication, modifying timing of a timer by using the high layer to calculate the number of frames that are assured to be out of synchronization within the timing; and when the number of frames that are assured to be out of synchronization reaches a predefined value within the timing, determining that radio link is out of synchronization, wherein the modifying the timing of the timer by using the high layer to calculate the number of frames that are assured to be out of synchronization within the timing comprises: suspending, by using the high layer, timing of the timer in the invalid frame, so that the high layer performs timing by using the timer only within valid frames that do not comprise the invalid frame indication, to calculate the number of frames that are assured to be out of synchronization within the timing, wherein the valid frame is a frame used for detecting out-of-synchronization.
