Abstract: The present invention relates to a method for increasing standby time of mobile terminal and device thereof, and more particularly in a mobile terminal that performs voice and/or data communication by switching between at least two networks using different protocols, and method for increasing standby time using an access history and the device thereof. According to the present invention, the minimized hybrid operation can increase the standby time of the mobile terminal. Also, by minimizing hybrid operation of a plurality of IS-856 mobile terminals, the resource efficiency of the EV-DO network can be maximized.

Abstract: A method, device and recorded medium having recorded the method, for providing directions information applied with real-time traffic condition reports are disclosed. An aspect of the present invention features a method and device that can receive traffic condition reports in real-time and provide directions information applied with the pertinent traffic condition reports. Accordingly, with the present invention, the directions information can be generated by using first real-time traffic condition reports. Then, the path directions applied with the change of traffic condition reports according to the time flow can be acquired and provided to a user.

Abstract: Disclosed is a CDMA terminal for providing a CDMA service to a global system for mobile communications (GSM) service subscriber in a CDMA service area which comprises: a subscriber identity module (SIM) cardholder for installing or uninstalling a SIM card of a GSM service subscriber, wherein when a SIM card of the GSM service subscriber is installed in the SIM cardholder in the CDMA service area, specific data are transmitted using a CDMA message in the case of authenticating the GSM service subscriber using information on the GSM service subscriber stored in the SIM card, and when the authentication of the GSM service subscriber is normally completed, the CDMA terminal is used for the GSM service subscriber as a roaming service terminal in the CDMA service area. According to the present invention, the GSM service subscriber can use his SIM card and number in the CDMA service area.
