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 by a mobile station and transmitting the voice mail password from the mobile station to a mobile telephone switching center when a user requests an outgoing call to another mobile station or a telephone set;

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

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 connection from the mobile station to the another mobile station or the telephone set is to be provided to the mobile station based on the determination; and

when it is determined that the voice mail password of the outgoing call message is consistent with the voicemail password of the voice mailing system, connecting the mobile station to the another mobile station or the telephone system without establishing a connection between the mobile station and the voice mailing system.

2. The method of claim 1, further comprising the step of requesting and receiving the 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 the 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 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.

5. The method of claim 1, further comprising the step of reading, by the mobile station, the voice mail password previously stored in the mobile station, wherein the mobile station automatically includes the read-out voice mail password in the outgoing call message when the user requests the outgoing call.

6. 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 when a user requests an outgoing call to another mobile station or a telephone set; 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 connection from the mobile station to the another mobile station or the telephone set 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,

wherein 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, the mobile telephone switching center connects the mobile station to the another mobile station or the telephone set without establishing a connection between the mobile station and the voice mailing system.

7. The system of claim 6, 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.

8. The system of claim 6, wherein the mobile telephone switching center requests and receives the user'"'"'s voice mail password from the voice mailing system.

9. The system of claim 6, 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.

10. The system of claim 6, wherein the mobile station reads the voice mail password from a memory, and the mobile station automatically includes the read-out voice mail password in the outgoing call message when the user requests the outgoing call.
