Abstract: A method in an electronic device includes receiving an input pattern, identifying a pattern identification (ID) from the input pattern, determining a counterpart electronic device corresponding to the pattern ID, and establishing a wireless connection with the corresponding electronic device. An electronic device includes a wireless communication unit configured to perform wireless communication with one or more other electronic devices, a pattern input unit configured to receive an input pattern, and a processor configured to identify a pattern from the input pattern, determine a counterpart electronic device with an ID corresponding to the pattern, and cause the wireless communication unit to wirelessly connect with the counterpart electronic device. Also, other embodiments are disclosed.

Abstract: A method and apparatus for updating a regional reference time of a mobile communication terminal by a regional standard time difference according to a Network Identity and Time Zone (NITZ) information change in an asynchronous transfer mode-based mobile communication system are provided. The method of updating a regional reference time of a mobile communication terminal includes determining whether new regional standard time information is received and calculating, if a regional standard time information is changed, a regional standard time difference, which may have a positive or negative value; and resetting the regional reference time by adding the regional standard time difference to a preset regional reference time.
