Problems solved by technology

[0003] Similar to the dual connectivity of the LTE system, the 5G system also supports Tight Interworking between the eNodeB and the 5G base station gNB. In the tightly coupled LTE and 5G scenario, when the network between the UE and the gNB is disconnected, the UE will SCG Failure will occur in the secondary cell group. At present, when SCG Failure occurs in UE, there is no complete solution for how to deal with the scenario of SCG Failure

Abstract

Disclosed are a method and device for processing an SCG Failure. The method comprises a secondary NodeB (SN) receiving a first message for indicating that a secondary cell group failure (SCG Failure) has occurred to a user equipment (UE), wherein the first message is information generated by a main NodeB (MN) after receiving the SCG Failure reported by the UE, and the first message carries a measurement result obtained by the UE when the SCG Failure occurs; a serving cell of the UE in the SN determining to perform PSCELL switching of the main and secondary cell according to the measurement result, so that the UE accesses the switched target PSCELL, or the SN determining to perform SN switching according to the measurement result so that the UE accesses the switched target SN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a SCG Failure processing method and equipment. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, that is, the 4G network, E-UTRAN (Evolved UMTS Terrestrial Radio Access Network, evolved UMTS Terrestrial Radio Access Network) consists of multiple eNodeBs (Evolved Node B, evolved base station), The eNodeB and EPC (Evolved Packet Core, Core Packet Network Evolution) are connected through the S1 interface, and the eNodeBs are connected through the X2 interface. In order to support higher data throughput, UE user equipment can implement dual connections through two eNodeBs. [0003] Similar to the dual connectivity of the LTE system, the 5G system also supports Tight Interworking between the eNodeB and the 5G base station gNB. In the tightly coupled LTE and 5G scenario, when the network between the UE and the gNB is disconnected...
