FIELD: communication.
SUBSTANCE: method involves determining the serving cell of the terminal based on the configuration state of the original search area of the terminal, when the terminal starts the operation of re-selecting the cell. The determination of a service cell provides the terminal defining at least one first cell as a service cell, if the original search call area is configured for the terminal, and the cell from the number of at least one first cell in the original search call area meets the criterion S. The determination of at least one first cell provides the terminal determining the service cell from the set of first cells based on the frequency priority information corresponding to each first cell, and/or information about the quality of each first cell, if at least one first cell is a set of first cells.
EFFECT: ensuring that the terminal can be located in the source area of the search call for as long as possible, which reduces the likelihood of the terminal initiating the process of updating location information and achieves the goal of reducing the load on the air interface for signal transmission.
