Abstract

The present invention is applicable to the field of communications technologies, and provides an in-synchronization and out-of-synchronization handling method and apparatus. The method includes: reporting, by a physical layer, an invalid frame indication to a high layer, where 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, so as to count the number of frames that are assured to be out of synchronization within timing; and when the number of frames that are assured to be out of synchronization within the timing reaches a predefined value, determining that a radio link is out of synchronization. By using the present invention, the modified timing of the timer and the number of in-synchronization indications correspond to each other.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and device for processing synchronization and desynchronization. Background technique [0002] Synchronization and out-of-synchronization judgment under Discontinuous Reception (DRX) of Continuous Packet Connectivity (CPC), the physical layer (also called layer 1, L1) of user equipment (User Equipment, UE) ) Out-of-synchronization detection is only performed on the radio frames of the effective fractional dedicated physical channel (F-DPCH) time slot (SOLT), and the detection result is reported to the upper layer of the UE. According to the existing 3GPP (Third Generation Partnership Project) protocol, after receiving multiple (such as N313) out-of-synchronization indications reported by the physical layer, the UE high layer starts a specific (number T313) timer. If the UE high layer receives multiple (such as N315) synchronization indications before t...
