FIELD: communication.
SUBSTANCE: described result is realised by: receiving, by the terminal, a first configuration information sent by the target base station, wherein the first configuration information contains at least one secondary node configuration; after receiving the first configuration information by the terminal, if the first configuration information contains one secondary node configuration, the secondary node configuration is in the active state; selecting, by the terminal, if the first configuration information contains multiple secondary node configurations, based on the results of measuring the signal of the cells in the inactive state, one secondary node configuration from the multiple secondary node configurations, and transmitting the selected secondary node configuration to the target base station, so that the secondary node configuration is in the active state.
EFFECT: provided possibility for the UE to configure the required secondary node (SN) information in an Msg4 message after the UE in the dual connection (DC) mode goes into the inactive state when the radio resource control (RRC) connection is restored.
