Method and system for base station handover

A method for base station handover, which is applied to user equipment (UE), the method comprising:

• sending a measurement report and UE excessively high-temperature indication information to a connected source base station upon detecting that a base station handover condition is met, when the temperature of the UE is not less than a preset value;
• sending a random-access request to a destination base station upon receiving a radio resource control (RRC) connection reconfiguration message sent by the source base station, so that the destination base station sets transmission configuration information;
• and
• receiving service data sent by the destination base station.

A base station, which is a destination base station of user equipment (UE), comprising a processor and memory, wherein the memory stores at least one instruction, at least one program, a code set, or an instruction set for execution by the processor to:

• receive a Handover Request message sent by a mobility management entity (MME), to which a destination base station is connected, via an S1 interface, wherein the Handover Request message carries UE excessively high-temperature indication information;
• send a Handover Request Acknowledge message to the MME via the S1 interface, so that the MME sends a Handover Command message to a source base station of the UE;
• set transmission configuration information for the UE based on the UE excessively high-temperature indication information after receiving a random-access request sent by the UE, wherein a data transmission rate corresponding to the set transmission configuration information is lower than a maximum data transmission rate that the destination base station can provide for the UE;
• and
• send service data to the UE based on the set transmission configuration information.
