Abstract
A method for performing roaming in a dual mode terminal, which includes a first wireless communication module corresponding to a first communication network and a second wireless communication module corresponding to a second communication network, is disclosed. The method comprises acquiring a public land mobile network (PLMN) identifier by camping on the first communication network; determining whether connection to the first communication network is roaming by comparing roaming decision information included in the PLMN identifier with roaming decision information stored in the dual mode terminal; turning off the second wireless communication module if it is determined that connection to the first communication network is roaming; and transmitting and receiving a signal to and from the first communication network.
