Abstract: Embodiments of this application provide a communication method, device, and system, to reduce energy consumption of a terminal device and accelerate reselection performed by the terminal device. In this solution, a network device determines a plurality of sub-areas, and sends area configuration information to the terminal device. The terminal device receives the area configuration information, determines a first sub-area based on the area configuration information, and performs measurement based on information about one or more neighboring frequencies corresponding to the first sub-area. A geographical area range including the plurality of sub-areas includes a coverage area of a first cell, the area configuration information indicates information about the plurality of sub-areas, and the first sub-area is a sub-area in which the terminal device is currently located in the plurality of sub-areas.
