Patent ID: 8391799

Claim:
A mobile communication terminal comprising: an antenna that performs transmission and reception of a wireless signal; a communication unit that performs communication with a base station by establishing a wireless communication line with the base station through the antenna; a memory unit that stores synchronization information of the wireless communication line established by the communication unit; a measuring unit that measures reception power level and signal quality of the wireless signal received by the antenna; and a cell search processor that detects the base station based on the synchronization information stored in the memory unit in a case where the reception power level is larger than a predetermined value and the signal quality is lower than a predetermined signal quality threshold value, wherein the synchronization information stored in the memory unit comprises: first synchronization information that is classified as a first synchronization information list; and second synchronization information classified as a second synchronization information list different from the first synchronization information list, and wherein the cell search processor detects the base station based on the first synchronization information in a case where the reception power level is larger than the predetermined value and the signal quality is lower than the predetermined signal quality threshold value and detects the base station based on the second synchronization information in a case where the reception power level is less than the predetermined value and the signal quality is lower than the predetermined signal quality threshold value.
