Serial number dynamic adjustment method and device, and base station

Abstract

The invention discloses a serial number dynamic adjustment method and device, and a base station, and relates to the field of communication. The serial number dynamic adjustment device receives uplinkdata sent by a user terminal, extracts a serial number of a specified protocol layer from the uplink data, judges whether the serial number exceeds a preconfigured maximum value or not, and adjusts the serial number by utilizing the maximum value and if the serial number exceeds the maximum value, so that the adjusted serial number does not exceed the maximum value. According to the serial numberdynamic adjustment method and device, the serial number is adjusted by utilizing the preconfigured maximum value, so that the adjusted serial number does not exceed the maximum value; and therefore,the problem of offline caused by inconsistent serial number configuration can be rapidly solved on the premise that the standard is not modified, so that a network configuration method is flexible, and the network overhead is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a serial number dynamic adjustment method, device and base station. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) network, the PDCP SN SIZE is defined in the PDCP (Packet Data Convergence Protocol) layer protocol, and the RLC (Radio Link Control, radio link layer control) is defined in the RLC layer protocol Protocol) SN (Sequence Number, serial number) SIZE, for the UM mode adopted by the VoLTE (Voice over LTE, voice service carried on LTE) service, PDCP SNSIZE and RLC SN SIZE have corresponding optional values. [0003] Through the test, it is found that when the SN SIZE of two adjacent base stations is configured with different values, the terminal will still send data according to the configuration 1 of the original base station A during the handover, while the switched base station B adopts the configuration 2, so the sequence will be found If...

AI Technical Summary

Problems solved by technology

[0003] Through the test, it is found that when the SN SIZE of two adjacent base stations is configured with different values, the terminal will still send data according to the configuration 1 of the original base station A during the handover, while the switched base station B adopts the configuration 2, so the sequence will be found If the number is wrong, the data will be discarded, resulting in a dropped connection

[0004] At present, the means to solve this problem is to uniformly configure a SN SIZE for all base stations. The network configuration method is very rigid and wastes network resources.
