Patent ID: 8504095

Claim:
An apparatus for acquiring a system in a mobile communication terminal, the apparatus comprising: a Radio Frequency (RF) communication unit for transmitting and receiving a radio frequency signal; a location signal receiver for receiving a location signal; a system list storage unit for storing a system list to be searched for acquiring a system; a system list management unit that arrays the system list stored in the system list storage unit based on location signals received by the location signal receiver; a timer that starts at a predetermined time interval to indicate elapse of the predetermined time duration; and a control unit for acquiring the system by searching the system list stored in the system list storage unit for a closest system to a current calculated location of the mobile communication terminal from the location signal received by the location signal receiver, wherein the control unit arrays the system list in order of geographical closeness of the systems to the current calculated location based on the received location signal, and searches the system list in order of the arrayed system list, wherein the system list includes a Most Recently Used (MRU) list and a Preferred Roaming List (PRL), which include coordinate information of a system location, and wherein the control unit starts the timer upon transforming the state of the mobile communication terminal into the idle state, and controls the system list management unit to array, upon elapse of the predetermined time duration, the system list stored in the system list storage unit in the order of closeness of systems to the current calculated location.
