Cell handover method

A cell handover method, performed by a core network device, comprising:

• receiving a handover request signaling and target terminal capability information of a multi-card terminal sent by a source base station corresponding to the multi-card terminal, wherein the target terminal capability information is configured to indicate at least one of following capabilities:
• a multi-card capability supported by the multi-card terminal, or a capability of the multi-card terminal to support reporting a multi-card problem;
• sending the handover request signaling and the target terminal capability information to a target base station corresponding to the multi-card terminal;
• and
• receiving a handover request acknowledgement signaling sent by the target base station;
• and
• sending a handover command to the source base station, wherein the handover request acknowledgement signaling is configured to indicate that the target base station accepts a cell handover request corresponding to the multi-card terminal based on the target terminal capability information;
• wherein the handover command comprises a third information unit configured to indicate target base station capability information, and the target base station capability information is configured to indicate a capability supported by the target base station to solve the multi-card problem existing in the multi-card terminal.

A cell handover method, performed by a target base station, comprising:

• receiving a handover request signaling and target terminal capability information of a multi-card terminal sent by a core network device, wherein the target terminal capability information is configured to indicate at least one of following capabilities:
• a multi-card capability supported by the multi-card terminal, or a capability of the multi-card terminal to support reporting a multi-card problem;
• determining to accept a cell handover request corresponding to the multi-card terminal based on the target terminal capability information;
• and
• sending a handover request acknowledgement signaling to the core network device;
• wherein the handover request acknowledgement signaling comprises a fifth information unit configured to indicate target base station capability information, and the target base station capability information is configured to indicate a capability supported by the target base station to solve the multi-card problem existing in the multi-card terminal.
