Cell measurement method and apparatus

A cell measurement method, comprising:

• sending, by a network device, first information to a terminal device, wherein the first information indicates a measurement parameter used by the terminal device to perform cell measurement in an inactive state, wherein the measurement parameter comprises validity area information that comprises a radio access network-based notification area (RNA) list that indicates that, after the terminal device leaves an area indicated in the RNA list, the terminal device does not need to perform cell measurement when the terminal device is in the inactive state, and wherein a detection signal for the cell measurement comprises at least a synchronization sequence or physical broadcast channel block (SSB) or a channel state information reference signal (CSI-RS);
• sending, by the network device, second information to the terminal device, wherein the second information is carried in a radio resource control (RRC) resume message, and wherein the second information indicates that the terminal device is allowed to report a measurement result of the cell measurement in an RRC resume complete message;
• and
• receiving, by the network device, the measurement result of the cell measurement.

A terminal device, comprising:

• a communications interface;
• at least one processor, connected to the communications interface;
• and a non-transitory computer readable memory storing a program to be executed by the at least one processor, the program including instructions for:
• receiving first information from a network device through the communications interface, wherein the first information indicates a measurement parameter used by the terminal device to perform cell measurement in an inactive state, wherein the measurement parameter comprises validity area information validity area information that comprises a radio access network-based notification area (RNA) list that indicates that, after the terminal device leaves an area indicated in the RNA list, indicating that, after the terminal device leaves a validity area, the terminal device does not need to perform cell measurement when the terminal device is in the inactive state, and wherein a detection signal for the cell measurement comprises at least a synchronization sequence or physical broadcast channel block (SSB) or a channel state information reference signal (CSI-RS);
