Abstract: A portable terminal and a method for originating a call through a substituted network when originating a call is barred due to overload of a first network is disclosed herein. A call may be originated by automatically switching the communication mode of the portable terminal from the first network such as an LTE network to a second network such as a 3G network or a 2G network, when originating a call is barred in the first network. The information of the cell of the second network is searched from a second network database stored in advance, which allows the time to search for a cell and time to register in the second network decrease. The searched cell with the highest power level may be selected and the call is originated through the selected cell of the second network.

Abstract: An apparatus to read data includes a command receiving unit to receive a read record command with respect to data stored in the apparatus, a record identification unit to identify a valid record from among records corresponding to the stored data based on the received read record command, and a data read unit to read data corresponding to the valid record. A method for reading data includes receiving a read record command with respect to data stored in an apparatus, receiving a read record command with respect to stored data, identifying a valid record from among records corresponding to the stored data based on the received read record command, and reading data corresponding to the identified valid record.

Abstract: A terminal and a method for supporting an emergency call in a terminal in which policy information regarding an emergency call may be received from a Public Land Mobile Network (PLMN) and used to select a PLMN supporting the emergency call for a current terminal and a base station of the PLMN.
