The present invention relates to a method and system for restoring a transferred mobile service by a mobile transfer service. To this end, the present invention provides a method for restoring a mobile service that releases a mobile transfer state of a first mobile terminal when it is confirmed that a state where the power strength of a common pilot channel received from a second mobile terminal is a previously set threshold value or less is maintained for a previously set threshold time or more. In addition, the present invention provides a method for restoring mobile service that releases a mobile transfer state of the first mobile terminal when it is confirmed that the frequency of a period that is the power threshold value or less of the common pilot channel received from the second mobile terminal exceeds the previously set threshold frequency within the previously set time unit. Further, the present invention provides a method for restoring mobile service that releases and restores the mobile transfer state of the first mobile terminal when the first mobile terminal is located in a service possible area and the second mobile terminal is located in a shadow area. According to the present invention, a situation where mobile communication service subscribers do not receive important mobile communication service can be prevented from occurring, which is caused by not performing a procedure of restoring the transferred mobile terminal.

Method and system for restoring transferred mobile terminal by mobile transfer service

The present invention relates to method and system for releasing terminal switching between a mobile terminal and a telematics terminal, and the method according to the present invention comprises receiving from the mobile terminal a terminal switching release request including an identification code representing terminal switching release; restoring information of the mobile terminal by inactivating information of the telematics terminal set as information of the mobile terminal in a home location register and activating information of the mobile terminal based on the identification code; and transmitting a mobile terminal activation command to a first switching center, where the mobile terminal is located, to allow a mobile communication service of the mobile terminal.

Method and system for providing transfer service between mobile terminal and telematics terminal

The present invention relates to a method for providing a linkage service of address book data between telematics and a mobile terminal by interworking with a mobile communication network.

Method and system for providing linkage service of address book data between telematics and mobile terminal

The present invention relates to method and system for providing a terminal switching service between a telematics terminal and a mobile terminal, and the method according to the present invention comprises a switching step for receiving a terminal switching request from the telematics terminal mounted in a vehicle on a mobile communication network and providing the telematics terminal with a mobile communication service to be provided to the mobile terminal; a restoration request receiving step for receiving a terminal switching restoration request from the telematics terminal that sensed another passenger in the vehicle on the mobile communication network; and a restoring step for restoring information of each terminal to a state before terminal switching on the mobile communication network according to the restoration request.
