Communication method, device, and system

A communication method, wherein the method comprises:

• generating area configuration information, wherein the area configuration information indicates information about a plurality of sub-areas, and a geographical area range of the plurality of sub-areas overlaps a coverage area of a first cell;
• and
• sending the area configuration information to a terminal device, wherein the area configuration information is usable for performing measurement based on information about one or more neighboring frequencies corresponding to a first sub-area, wherein the first sub-area is a sub-area in which the terminal device is currently located and the first sub-area is one sub-area of the plurality of sub-areas, and the one or more neighboring frequencies is of the first cell.

A communication apparatus, wherein the communication apparatus comprises at least one processor and non-transitory memory, wherein the memory stores a program to be executed by the at least one processor, the program including instructions for:

• receiving area configuration information from a network device, wherein the area configuration information indicates information about a plurality of sub-areas, and a geographical area range of the plurality of sub-areas overlaps a coverage area of a first cell;
• and
• performing measurement based on information about one or more neighboring frequencies corresponding to a first sub-area, wherein the first sub-area is a sub-area in which the terminal device is currently located and the first sub-area is one sub-area of the plurality of sub-areas, and the one or more neighboring frequencies is of the first cell.
