Abstract

A mobile station includes a voice mail password in an outgoing call message for a call, a data communication and the like. A mobile telephone switching center determines whether the voice mail password of the outgoing call message from the mobile station is consistent with the voice mail password from the voice mailing system, and provides the call service to the corresponding mobile station when they are consistent with each other. The voice mail password can be registered or changed after the user connects to the voice mailing system and is identified for the voice mail service. Therefore, the user can just merely change the voice mail password, thereby preventing unauthorized use of the mobile station.

Claims

1. A user identification method in a mobile communication system, the method comprising the steps of:

including a voice mail password in an outgoing call message and transmitting the voice mail password from a mobile station to a mobile telephone switching center when a user requests an outgoing call;

receiving the outgoing call message from the mobile station in the mobile telephone switching center; and

determining whether the voice mail password of the outgoing call message is consistent with a voice mail password of a voice mailing system and determining, in the mobile telephone switching center, whether a call service is to be provided to the mobile station based on the determination.

2. The method of claim 1, further comprising the step of requesting and receiving a corresponding user'"'"'s voice mail password of the voice mailing system in the mobile telephone switching center.

3. The method of claim 1, wherein when the mobile communication system is a UMTS (Universe Mobile Telecommunications System), in the step of including a voice mail password in the outgoing call message, the voice mail password is included in a mobile identity field of a CM (Control Management) service request message.

4. The method of claim 1, further comprising the step of providing the call service to the mobile station in the mobile telephone switching center when it is determined that the voice mail password of the outgoing call message is consistent with the voice mail password of the voice mailing system.

5. The method of claim 1, further comprising the step of transmitting a call termination message from the mobile telephone switching center to the mobile station when it is determined that the voice mail password of the outgoing call message is not consistent with the voice mail password of the voice mailing system.

6. The method of claim 1, further comprising the step of reading the voice mail password previously stored in the mobile station, and including the read-out voice mail password in the outgoing call message.

7. A mobile communication system for user identification, the system comprising:

a mobile station for including a voice mail password in an outgoing call message and transmitting the voice mail password to a mobile telephone switching center; and

the mobile telephone switching center for determining whether the voice mail password of the outgoing call message is consistent with a voice mail password of a voice mailing system and determining whether a call service is provided to the mobile station depending on, the consistency when the mobile telephone switching center receives the outgoing call message from the mobile station.

8. The system of claim 7, wherein the mobile telephone switching center provides the call service to the mobile station when the voice mail password of the outgoing call message is consistent with the voice mail password of the voice mailing system.

9. The system of claim 7, wherein the mobile telephone switching center transmits a call termination message to the mobile station when the voice mail password of the outgoing call message is not consistent with the voice mail password of the voice mailing system.

10. The system of claim 7, wherein the mobile telephone switching center requests and receives a corresponding user'"'"'s voice mail password from the voice mailing system.

11. The system of claim 7, wherein when the mobile communication system is a Universal Mobile Telecommunications System (UMTS), the mobile station includes the voice mail password in a mobile identity field of a Control Management (CM) service request message.

12. The system of claim 7, wherein the mobile station reads the voice mail password from a memory.

13. A user identification method in a mobile station, the method comprising the steps of:

receiving an outgoing call request from a user;

including a voice mail password in an outgoing call message and transmitting the voice mail password to a mobile telephone switching center; and

providing a call service from the mobile telephone switching center when the voice mail password of the outgoing call message is consistent with a voice mail password of a voice mailing system.

14. The method of claim 13, wherein the voice mail password is previously stored in a memory.

15. The method of claim 13, further comprising the step of receiving a call termination message from the mobile telephone switching center when the voice mail password of the outgoing call message is not consistent with the voice mail password of the voice mailing system.

16. The method of claim 13, wherein in the step of including a voice mail password in the outgoing call message, the voice mail password is included in a mobile identity field of a Control Management (CM) service request message when a mobile communication system is a Universal Mobile Telecommunications System (UMTS).

17. The method of claim 13, wherein the step of receiving a call service from the mobile telephone switching center, further comprises:

receiving a reply message from the mobile telephone switching center; and

determining whether the reply message is a call termination message.
