Cell handover method and apparatus, and storage medium

A cell handover method, applied to a network device, comprising:

• transmitting a first message to a terminal through a first cell, wherein the first message indicates the terminal to perform a cell handover with an enhanced handover characteristic or a cell handover with a non-enhanced handover characteristic, to cause a handover of the terminal from the first cell to a second cell, and the cell handover with the enhanced handover characteristic comprises a conditional handover (CHO) or a dual active protocol stack (DAPS) handover;
• transmitting a second message to the terminal through the second cell, wherein the second message indicates the terminal to perform the cell handover with the enhanced handover characteristic;
• and
• detecting whether the terminal has recorded a radio link failure (RLF) report during a process of performing a handover from the second cell to a third cell according to the second message and when an RLF occurs in the second cell;
• if the terminal has recorded the RLF report, generating a failure indication message, wherein the failure indication message is used for parameter optimization of the cell handover, and timing duration is recorded in the RLF report, wherein the timing duration is elapsed time from reception of the first message by the terminal to occurrence of the RLF in the second cell.

A cell handover apparatus, applied to a terminal, comprising:

• a memory, a transceiver, and a processor;
• the memory is configured to store a computer program;
• the transceiver is configured to receive and transmit data under the control of the processor;
• the processor is configured to read the computer program in the memory and perform the following operations:
• receiving a first message transmitted by a first cell, wherein the first message indicates the terminal to perform a cell handover with an enhanced handover characteristic or a cell handover with a non-enhanced handover characteristic, and the cell handover with the enhanced handover characteristic comprises a conditional handover (CHO) or a dual active protocol stack (DAPS) handover;
• performing a handover from the first cell to a second cell according to the first message;
• receiving a second message transmitted by the second cell, wherein the second message indicates the terminal to perform the cell handover with the enhanced handover characteristic;
• and
• performing a handover from the second cell to a third cell according to the second message, and generating a radio link failure (RLF) report and recording timing duration in the RLF report if an RLF occurs in the second cell, wherein the timing duration is elapsed time from reception of the first message by the terminal to occurrence of the RLF in the second cell.
