Abstract:
1. A cell search method in a mobile communication terminal to be used in an environment in which a plurality of common carriers run respective networks using different frequency bands within a specified range of frequencies, the method comprising: searching for a plurality of cells to find a cell of a desired network; storing first frequency band information together with corresponding network information having been searched during finding the cell of the desired network; determining each frequency band among the specified range of frequencies whose band allocation is continuing and adjacent to the first frequency band information corresponding to the cell of the desired network as second frequency band information for selection; assigning a high priority to the second frequency band information, and storing the second frequency band information together with the assigned high priority; and finding a frequency included in the second frequency band information according to the assigned high priority when the frequency being used in the desired network is lost.
