  • Publication number: 20090298497
    Abstract: A multiband mobile terminal and cell search method is provided for reducing the camp-on delay by storing an indicator extracted from system information transmitted by the base station on which the mobile terminal has most recently camped, and scanning the frequency bands, indicated by the band indicators first. The multiband mobile terminal supporting at least two frequency bands includes a radio frequency (RF) unit that receives system information; a storage unit; and a control unit that controls mobile terminal to scan, when a camp-on event is detected, a frequency band indicated by the band indicator, camp on a base station of a network using the frequency band, and store a band indicator indicating the network. The multiband mobile terminal scans the frequency band of the network in which the mobile terminal locates, resulting in reducing the time required for camping on a cell.
