Abstract

The invention discloses a method and a device for processing connection failure in a dual-connection system, and a storage medium, which are used for solving the technical problem that in the dual-connection system in the prior art, when a user terminal generates MCG failure in a main base station, the connection between the user terminal and a network side cannot be maintained. The method comprises the following steps: receiving main serving cell set MCG failure information sent by the user terminal and a channel measurement report of the user terminal; determining whether to perform master base station switching on the user terminal based on the channel measurement report; if it is determined that main base station switching is performed on the user terminal, sending a switching requestmessage to a target main base station, wherein the switching request message carries indication information used for indicating that the user terminal has an MCG failure in the source main base station.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and storage medium for handling connection failure in a dual connection system. Background technique [0002] In the Long Term Evolution (LTE) system, the Evolution-Universal Terrestrial Radio Access Network (E-UTRAN) is composed of multiple base stations (eNodeB), and the eNodeB and the core network (Evolved Packet Core, EPC) are connected through the S1 interface, and eNodeBs are connected through the X2 interface. In order to support higher data throughput, a user terminal (User Equipment, UE) may implement dual connectivity through two eNodeBs. One of the eNodeBs serves as a master base station (Master Node, MN), and has a control plane connection with the core network; the other eNB serves as a secondary base station (Secondary Node, SN), and has no control plane connection with the core network. [0003] In the 5th Generation mobile communication technol...
