The present invention has been made to solve the above-mentioned problems, by entering the calling number to the trace number of the sender to send a short message of inappropriate content, thereby protecting the privacy of the recipient and sending indiscriminate short messages The purpose of the present invention is to provide a mobile communication system and a method for tracking the sender of a message that can prevent the error.

According to an aspect of the present invention, there is provided a mobile communication system and a method for tracking a sender of a message, the method including: receiving a caller's telephone number confirmation request of the short message from a receiver receiving the short message at an exchange; Retrieving the caller's unique telephone number stored in a home location register at the request of the recipient; Checking whether or not the retrieved unique telephone number of the caller and the telephone number of the caller included in the short message match; If the caller's phone number does not match the unique phone number, characterized in that it comprises the step of providing the caller's unique telephone number to the mobile communication terminal of the receiver.

Here, the unique telephone number of the caller is preferably provided in a short message format to the mobile communication terminal of the receiver.

And, it is possible that the receiver receiving the short message, requesting confirmation of the caller's telephone number of the short message by retransmitting the received short message to the exchange side.

On the other hand, the above object according to another field of the present invention, the home location register for storing the unique information of the user of the mobile communication terminal; A short message center for sending a short message to the mobile communication terminal; When a request for confirming the caller's telephone number of the short message is received from a receiver who receives the short message through a mobile communication network, it is determined whether or not the caller's unique telephone number stored in the home location register matches the caller's telephone number included in the short message. And confirming that the caller's telephone number does not match with the unique telephone number, the mobile telephone having a caller tracking function for providing a caller's unique telephone number through the short message center. It is also achieved by the system.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to a mobile communication system and a message sender tracking method according to a preferred embodiment of the present invention.

1 is a block diagram of a mobile communication system according to the present invention. As shown in FIG. 1, a mobile communication system includes wireless communication between a base station transceiver system (BTS) 14 and a mobile communication terminal 20, 22 located in a service area of a receiving base station 16. Makes it possible. Each base station 14, 16 is controlled through a base station controller (BSC) 10, 12 and a mobile switching center (MSC) 1, and the exchange 1 is a home location register (HLR). : In connection with the Home Location Register (5) and the Message Center (SMSC) (3), it relays voice calls or message transmissions between the two mobile communication terminals 20 and 22 and provides various additional services.

The home location register 5 is a database for managing various types of information of mobile subscribers and has information on subscription of additional services such as SMS and CB. The home location register 5 performs the unique information and location registration functions of the mobile communication terminals 20 and 22 and subscribers in conjunction with various base station control devices 10 and 12 / switch 1.

The exchanger 1 connects to the base station controllers 10 and 12 to perform call setting and release functions of the mobile communication terminals 20 and 22, and performs various functions related to call processing and additional services, and moves to the calling party. The short message transmitted from the communication terminal 20 is transmitted to the receiving mobile communication terminal 22 through the message center 3.

Here, when the user of the receiving mobile communication terminal 22 receiving the short message requests the caller tracking, the exchange 1 transmits the calling party mobile communication terminal 20 caller information stored in the home location register 5. It reads and checks whether or not the information of the sender transmitted to the receiving party and the information stored in the home location register 5 is provided to the receiving mobile communication terminal 22. That is, when the caller's phone number stored in the home location register 5 matches the caller's phone number input in the short message, the receiver is notified, and the caller's phone number included in the sent short message is the home location register 5. If the caller phone number stored in the inputted and transmitted differently, provides the caller phone number stored in the home location register (5) to the receiving side.

In this case, the receiver may question whether the caller's telephone number sent with the short message is an actual telephone number.

When the user wants to know the actual telephone number of the caller, the user who receives the short message requests the tracking of the short message sender through the base station 16 (S12). Here, the receiving user may request the sender tracking of the received short message by retransmitting the short message to the sender to the receiving base station 16.

The short message sender tracking request is transmitted to the exchange 1 through the receiving base station 16 (S14), so that the exchange 1 sends the sender information of the short message sent from the home location register 5 to the exchange 1. Read it and check whether it matches with the caller information included in the short message (S16).

As a result of the check, when the caller's phone number included in the sent short message is input and transmitted differently from the caller's phone number stored in the home location register (5), the caller's phone number is notified and the receiving user's mobile communication terminal is notified. The actual caller's telephone number is guided to (22) (S18).

Then, when the caller's phone number stored in the home location register 5 matches the phone number input in the short message, the receiving user is notified that the caller information is true (S20).                     

Here, the fact of the caller's telephone number is preferably provided to the receiving mobile communication terminal 22 in the form of a short message, but may be provided in the form of a voice message.
