METHOD FOR OPEN COMMUNICATION SUPPORTING DUAL MODE IN MOBILE TERMINAL

摘要

A communication opening method in a dual mode portable terminal is provided to open a portable terminal to communication in an integrated method by providing an OTA(Over The Air) opening method using not a short message but a packet data call. A control part in a dual mode portable terminal enters into an OTA opening mode(S201), and reboots the portable terminal(S207). If the portable terminal is turned on again as the rebooting of the portable terminal is completed, the control part displays what the portable terminal has accessed the OTA opening mode(S209). If an input signal for the start of OTA opening is detected(S211), the control part makes a packet data call to a mobile carrier(S213). Also the control part transmits OTA opening information, stored in the portable terminal, to the mobile carrier(S215). Receiving the packet data call, the mobile carrier receives and stores the OTA opening information(S217,S219). The mobile carrier confirms the OTA opening information(S221), and approves OTA communication for the communication modes the portable terminal supports(S223). Then the mobile carrier transmits an OTA opening approval signal to the portable terminal(S225). Receiving the OTA opening approval signal, the control part confirms that OTA opening with the mobile carrier has been completed(S227,S229).
