Problems solved by technology

[0016] Obviously, in the joint work scenario of LTE and NR tight interworking in the 5G system, once the configuration of SCG configuration information fails, even if the configuration of MCG configuration information is successful, the MCG will initiate RRC reconstruction. In this way, serious data interruption will occur, which will seriously affect Normal communication of user equipment

example 1

[0175] Example 1: When the first base station is a MeNB, the first base station will determine that the MCG configuration is successful and the SCG configuration fails when receiving the SCG reconfiguration failure information sent by the UE. At this time, the first base station will use the successfully configured MCG configuration information , and send SCG reconfiguration failure information to SeNB, trigger SeNB to maintain the original SCG configuration information unchanged or trigger SeNB to perform SCG release; or, the first base station will receive SCG reconfiguration failure information sent by UE (may not be Send MCG configuration information), determine that MCG configuration is not performed, SCG configuration fails, at this time, the first base station will maintain the original MCG configuration information unchanged, and send SCG reconfiguration failure information to SeNB, trigger SeNB to maintain the original SCG configuration information change or trigger th...

Abstract

The present invention relates to the technical field of mobile communication, in particular to a cell configuration method and device, which are used to avoid severe data interruption and ensure normal communication of user equipment. The method is as follows: in the joint application scenario of MeNB and SeNB, the first base station sends SCG configuration information to UE for SCG configuration, and when UE determines that SCG configuration fails, it sends SCG reconfiguration failure information to the network side. At this time, When the UE and the network side determine that the MCG has not been configured and fails, they will keep the original SCG configuration information delivered last time unchanged, or trigger the execution of the SCG release. That is, when only the SCG configuration fails, RRC reconstruction will not be initiated frequently, but the original SCG configuration information will be used. In this way, serious data interruptions are effectively avoided, normal communication of the user equipment is guaranteed, and data transmission is improved. Efficiency ensures system performance and improves user experience.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a cell configuration method and device. Background technique [0002] With the development of network technology, people's demand for mobile networks is increasing. Improving user throughput is a major trend in the development of mobile communication technology in the future, and wireless resource aggregation between nodes is a potential technical solution for improving user throughput. At present, the Long Term Evolution-Advanced (LTE-A) dual connectivity technology and the tight interworking technology (tight interworking) of LTE and New Radio Access (New RAT, NR) in the 5G system both use wireless resource aggregation between nodes. technology. [0003] Taking the dual connectivity technology of the LTE-A system as an example, the dual connectivity technology means that the user equipment (UE) can use the wireless spectrum resources of two base stations t...
