Description

Lost terminal location notification method using mobile communication terminal with GPS function and mobile communication terminal using same {Method and Device for Notifying Position of Lost Mobile Communication Device using GPS}

The present invention is a lost terminal location notification method using a mobile communication terminal equipped with a GPS function and a mobile communication terminal using the same, more specifically, a user who lost a mobile communication terminal having a GPS function, the fact of the loss of a mobile communication service system or lost notification The server for notifying, and the lost notification server notified of the fact of the loss relates to a method for receiving the current location information from the lost terminal and notifying the user's personal mailbox or e-mail server and a mobile communication terminal using the same.

Recently, with the widespread use of mobile communication services, almost all citizens are provided with one or more mobile communication services. These mobile communication services are being expanded to include basic voice calls, text and voice message transmissions, wireless Internet services, and location tracking functions.

Among these, the location tracking function using a mobile communication terminal may be implemented by a method using a cell location registered in a home location register (HLR) and a method using location information by a global positioning system (GPS). .

The method using the cell location information with the terminal has a radius of the cell, that is, the error of about several km, so it is difficult to accurately track the position. However, if the GPS or DGPS (Differential GPS) system is used, the error of several m to tens of meters Branches can provide relatively accurate location information.

Recently, the GPS positioning function "gpsOne" has been added to Qualcomm's CDMA modem chip, MSM 3300. Using GPS signals from satellites, fast and accurate positioning can be achieved.

However, until now, the GPS function provided to the terminal only informs the location information and the time of day, and has not been proposed for various services using the same.

On the other hand, as the use of mobile communication terminals increases, the loss of terminals also occurs a lot. When the terminal is lost, the user has to make a phone call to the lost terminal, call the acquirer of the lost terminal, and then recover the terminal. In particular, when the learner of the lost terminal has a malice or the power is turned off, there is no way to talk to the learner, so it is difficult to identify the location of the lost terminal at all. In addition, for example, the terminal is often lost in a limited space such as one's own home or office, and in this case, many people give up misunderstanding that they are misunderstood as being lost outside.

In this case, the base station and the HLR can be used to determine the cell (cell) where the lost terminal is located, but the mobile communication service provider does not provide such a positioning service, if the cell size is large, such as islands Since only approximate location is possible, it is not very helpful for the detection of the lost terminal.

The present invention has been made in view of the above, and it is intended to enable the location of a lost terminal by using relatively accurate current terminal location information transmitted by a terminal having a GPS function.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for enabling the positioning of a lost terminal using a mobile communication terminal having a GPS function and a mobile communication terminal using the same.

The entire system consists of a mobile communication terminal 100 having the above-described function, a server 200 for the loss notification, a mobile communication service system 210 for providing a personal voice mailbox function, and a mobile communication network 220 connecting the same. have. In addition, the notification using the e-mail should be provided with one or more e-mail server 230, each terminal user has an account, and the Internet network 240 for connecting the server and mail server for notification of loss. In addition, although not shown, an external GPS positioning system may be additionally included.

The loss notification server 200 receives a lost report of a terminal input by a user directly or through a mobile communication service system using any communication means, a user authentication function, and current location information received from the terminal. It receives and demodulates the data and saves it in the internal and external database. If a lost report is received, it generates a data (message) including the current location information of the lost device and sends it to the user's personal voice mailbox or e-mail server. Must be capable of transmitting

In addition, each user has a user database 201 that stores terminal information, a lost notification method, a destination address information for lost notification, and the like, so that the user database can periodically notify the location of the lost terminal. Notification period information may be further included. This information is entered and stored when subscribing to a mobile communication service or when applying for a separate loss notification service.

The function of such a lost notification server may be implemented by software produced in a predetermined programming language.

The mobile communication service system 210 is a system for providing a wireless communication service. The mobile communication service system 210 includes a base station, a wireless telephone exchange, a home location register, and the like, and has a storage space for storing data (primarily voice data) for each user. A personal mailbox; Therefore, after accessing a mobile communication service system using another communication means without using a terminal and inputting a terminal number and a password of the user, the user can check a voice message stored in his or her mailbox.

Such voicemail services, other mobile communication networks, Internet networks, and e-mail servers are currently used technologies, and thus detailed descriptions thereof will be omitted.

3 is a flowchart illustrating an embodiment of a terminal lost notification method according to the first embodiment of the present invention.

First, if the user lost the terminal, via the mobile communication service system or directly connected to the server for loss notification after receiving the user authentication (S310). Lost notification server searches the user database to extract the identification code (telephone number) of the corresponding lost terminal, and sends the current location transmission request to the terminal (S311). Receiving the current location transmission request, the terminal controller extracts the current location information of the terminal from the GPS receiver (and external GPS positioning system if necessary) and transmits it back to the server for notifying the loss (S312).

Lost notification server stores the current location information of the terminal in the database, and generates a text message (mail) or voice message containing the location information (S313), the personal mailbox of the user provided in the mobile communication service system Store in or send an e-mail to the registered mail account of the user (S314).

If the user requests the "periodical notice" in advance (S315), the server for loss notification checks the "notification period" set by the user, and when the notification period has elapsed since the last location information notification time, The current location transmission request, the current location extraction and transmission process, and the notification process of the terminal is repeatedly performed (S316). Of course, it is not necessary for the user to actively set the "notification cycle", but may be predetermined by default.

Therefore, when the lost mobile communication terminal moves, it is possible to periodically determine the movement path of the terminal even if the user does not report the loss every time.

Here, the location information extracted and transmitted by the terminal is mainly location information such as longitude and latitude, and may be notified of such location information. However, administrative location information corresponding to the location information with reference to an external geographic information database (eg For example, it may be desirable to extract the main facilities such as building numbers, subway stations, large buildings, etc., and notify them with positioning information.

4 is a flowchart illustrating a final location notification service of a lost terminal powered off according to a second embodiment of the present invention.

First, the controller of the terminal automatically extracts the current location information by driving the GPS receiver (and external GPS positioning system if necessary) when the terminal power is off, and sends it to the mobile communication service system and / or the server for loss notification. send. The mobile communication service system or the lost notification server that receives the data stores the location information and the time information when the power is turned off together with the corresponding terminal information (S410 and S411).

On the other hand, if the user lost his terminal through the mobile communication service system or directly connected to the server for loss notification after receiving the user authentication report (S412). Lost notification server checks the current state of the terminal to determine whether the power is on (S413).

When the power is turned on, the procedure according to the first embodiment described above may be performed to notify the current position once or periodically (S419).

When the power is turned off, the mobile terminal extracts the location information when the power is turned off by referring to the database of the mobile communication service system or the mobile communication service system, and generates a text message (mail) or voice message including the location information when the power is turned off ( S415, S416), stored in the personal mailbox of the user provided in the mobile communication service system, or sends an e-mail to the registered mail account of the user (S417). Therefore, the user can grasp the final position of the terminal, that is, the position information when the power is turned off.

Of course, in case the power is turned off and then on again, this process may be repeated every predetermined time to provide real time location information of the mobile communication terminal (S418).
