A method and device for searching for a network in a wireless communication environment supporting a plurality of communication methods are provided. An example method to support Simultaneous Voice and LTE (SVLTE) and Circuit Switch-FallBack (CSFB) involves determining a communication mode when a booting or rebooting event or no-data service event occurs, and only searching for a signal related to a selected one of the communication modes, thereby reducing total scan time needed to access a network.

Network searching by device supporting multiple communication methods

An apparatus and method for improving the performance of a determination of whether an earphone is mounted to a portable terminal, such as a portable terminal supporting a 3.5 mm earphone plug, are provided. An apparatus for recognizing whether the earphone is mounted to the portable terminal includes a common ground terminal and a switching terminal of an earphone plug receptacle for electrically connecting to each other and the same pole of an earphone plug when the earphone plug is mounted in the earphone plug receptacle, and an external output managing unit for generating an earphone mounting notification signal through a detector.
