Abstract

The invention relates to the technical field of wireless communication, in particular to a switching method and switching equipment, and aims at solving the problem of switching failure in a scene ofestablishing dual connection or multi-connection in a switching process. According to the embodiment of the invention, a source main node receives MCG configuration information of a target main node and SCG configuration information of at least one target auxiliary node sent by the target main node through one or more switching commands; and the source main node determines a target switching command needing to be sent to the terminal according to the one or more switching commands, and sends the target switching command to the terminal. By adopting the mode of the embodiment of the invention,switching failure can be avoided in a scene of establishing dual connection or multi-connection in the switching process, and the system reliability is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for switching. Background technique [0002] In an EN-DC (E-UTRA NR Dual Connectivity, E-UTRAN NR dual connectivity) scenario, a UE (User Equipment, user equipment) performs dual connectivity. The UE establishes connections with two access nodes at the same time to increase the data output rate. [0003] In the LTE (Long Term Evolution, long-term evolution) system, the access network is composed of multiple access nodes, the access nodes are connected to the EPC (Evolved Packet Core, core network) through the S1 interface, and the access nodes are connected through The X2 interface is connected, and in order to support higher data throughput, a UE (User Equipment, user equipment) can establish network connections with multiple access nodes at the same time. In the 5G system, similar to the dual connection of the LTE system, the dual co...
