Method and device for controlling mobility of terminal, and terminal

A method for controlling mobility of a terminal, comprising:

• after receiving configuration of a Signal Radio Bearer (SRB) 1, entering, by the terminal, a Radio Resource Control (RRC) connected state;
• in response to that the terminal in the RRC connected state does not receive configuration of a Data Radio Bearer (DRB) and/or configuration of an SRB2, reporting, by the terminal based on measurement configuration of the network side, a measurement result to the network side, wherein the measurement result is used by the network side to determine a target cell;
• and
• receiving, by the terminal, an RRC release message from the network side, wherein the RRC release message carries reference information of the target cell.

A device for controlling mobility of a terminal, applied to a terminal, the device comprising:

• a memory storing processor-executable instructions;
• and
• a processor configured to execute the stored processor-executable instructions to perform operations of:
• obtaining a first threshold configured by a network side;
• after receiving configuration of a Signal Radio Bearer (SRB) 1, entering a Radio Resource Control (RRC) connected state;
• and
• in response to that the terminal in the RRC connected state does not receive configuration of a Data Radio Bearer (DRB) and/or configuration of an SRB2, determining, based on a measurement result of a serving cell and the first threshold, whether to release an RRC connection and return to an idle state.
