Abstract

The invention provides an RLC state variable synchronization method and device, a base station and a storage medium, and the method comprises the following steps: carrying out the initialization of resources after receiving a fault switching message; after resource initialization is completed, receiving an RLC PDU sent by the user terminal in the uplink direction, analyzing an SN number based on the RLC PDU, and matching an RLC receiving state variable of the base station end with the SN number; and generating an RLC synchronous data packet, and sending the RLC synchronous data packet to the user terminal in a downlink direction, so that the user terminal synchronizes the RLC receiving state variable of the user terminal with the RLC sending state variable of the base station terminal according to the RLC synchronous data packet. According to the RLC synchronization method and device, after main and standby switching is conducted due to faults, the base station end is triggered, uncertainty of triggering of the user terminal is avoided, time intervals do not exist, the reliability of RLC synchronization is improved, and the service continuity of the base station and the user terminal during switching is improved.

Description

technical field [0001] The present invention relates to the field of private network communication, and more specifically, relates to an RLC state variable synchronization method, device, base station and storage medium. Background technique [0002] In order to make the base station operate with high reliability, a main service board and a backup service board are generally set in the base station. When the main service board fails, the backup service board is used instead of the main service board to continue processing communication services. When switching between the main service board and the standby service board (that is, active-standby switchover), it is necessary to match the service status parameters on the standby service board with the user terminal synchronously, so as to realize the continuous maintenance of the application layer service. [0003] Among them, RLC (Radio Link Control, radio link control protocol) state variables are a group of key parameters to...
