1. A handover configuration method, applied to a terminal device and comprising:
receiving target handover configuration information and handover configuration valid information that are sent by a network device, the handover configuration valid information comprising valid area information and/or valid timer information, the valid area information being used for indicating a valid area of at least part of the target handover configuration information, the valid timer information being used for indicating a valid duration of at least part of the target handover configuration information;
keeping at least part of the target handover configuration information valid in a case that a current cell of the terminal device is located in the valid area; or
keeping at least part of the target handover configuration information valid in a case that a current moment is within the valid duration; or
keeping at least part of the target handover configuration information valid in a case that a current cell of the terminal device is located in the valid area and a current moment is within the valid duration; wherein
the target handover configuration information comprises one or more of following:
a handover command, a conditional handover trigger condition, a measurement configuration, a measurement target configuration, a measurement report configuration, or a random access channel (RACH) configuration of a candidate cell;
in a case that the current cell of the terminal device is located in the valid area and handover configuration information incrementally configured by the network device is received, using incrementally configured handover configuration information and keeping handover configuration information that is not incrementally configured in the target handover configuration information valid.
