Abstract

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.

Claims

1. A method for providing a call information message of a non-received call in a terminal transfer service, which provides a call information message of a non-received call in a terminal switching state from a mobile terminal to a telematics terminal in a mobile communication system, the method comprising:

(a) processing a call destined for the mobile terminal by the telematics terminal;

(b) in the case that the telematics terminal is in a non-receiving state, writing a call information message of a non-received call; and

(c) temporarily allowing the mobile terminal to receive the written call information message and transmitting the written call information message to the mobile terminal.

2. The method for providing a call information message of a non-received call in a terminal transfer service according to claim 1,

wherein the step (b) inserts an indicator into the call information message, where the indicator represents that a corresponding message is a call information message of a non-received call, and

wherein the step (c) temporarily allows the mobile terminal to receive the call information message based on the indicator.

3. The method for providing a call information message of a non-received call in a terminal transfer service according to claim 1,

wherein the step (b) includes:

a switching center for the telematics terminal requesting call information message transmission to a home location register storing a profile of the mobile terminal;

the home location register requesting call information message transmission to a call information providing server; and

the call information providing server writing a call information message.

7. The method for providing a call information message of a non-received call in a terminal transfer service according to claim 2,

wherein the step (b) includes:

a switching center for the telematics terminal requesting call information message transmission to a home location register storing a profile of the mobile terminal;

the home location register requesting call information message transmission to a call information providing server; and

the call information providing server writing a call information message.

4. A system for providing a call information message of a non-received call in a terminal transfer service, which provides a call information message of a non-received call in a terminal switching state from a mobile terminal to a telematics terminal, the system comprising:

a first switching center serving as a switching center for the telematics terminal and configured to process a call destined for the mobile terminal by the telematics terminal;

a home location register for storing a profile information of the mobile terminal, and in the case that the telematics terminal is in a non-receiving state, receiving from the first switching center a request for transmission of a call information message of a non-received call;

a call information providing device for writing a call information message of a non-received call and transmitting the call information message via a message center according to the request of the home location register; and

a second switching center serving as a switching center for the mobile terminal and configured to receive the call information message, temporarily allowing the mobile terminal to receive the received call information message, and transmitting the call information message to the mobile terminal.

5. The system for providing a call information message of a non-received all in a terminal transfer service according to claim 4,

wherein the second switching center intercepts a mobile communication service of the mobile terminal except the call information message of a non-received call.

6. The system for providing a call information message of a non-received call in a terminal transfer service according to claim 4,

wherein the home location register routes to the first switching center an incoming call of the mobile terminal except the call information message of a non-received call.

8. The system for providing a call information message of a non-received call in a terminal transfer service according to claim 5,

wherein the home location register routes to the first switching center an incoming call of the mobile terminal except the call information message of a non-received call.
