Abstract: Provided are an apparatus and method for generating a Public Land Mobile Network (PLMN) list in a mobile communication terminal. The method includes: generating an available PLMN list by searching PLMNs through a Radio Frequency (RF) channel, and determining if Location Area Code (LAC) information is contained in the available PLMN list; generating a PLMN list from PLMN information matched with Mobile Country Code (MCC) information and Mobile Network Code (MNC) information and existing in a Subscriber Identity Module (SIM) card, when no LAC is contained in the available PLMN list; and deleting items duplicated in the generated PLMN list.

Abstract: A time control apparatus, which is not equipped with an auxiliary batter for real time control, includes a time information memory for storing real time information updated for a user; and a real time controller, in response to powering on, if the real time information stored in the time information memory is earlier than time information of the real time controller, displaying the real time information of the real time controller to a user and simultaneously updating the real time information in the time information memory without performing a time setting operation. It is possible to discern between a powering-off case where the battery is not removed from the terminal and a powering-off case where the battery is removed from the terminal in order to avoid a time setting operation that is unnecessary to the user.
