The present invention relates to a friend location search service using a mobile communication network, and in particular, by inputting a telephone number and an identification number of a service type of a requesting terminal to find a location in a text message writing environment of a mobile communication terminal, requesting location tracking. The present invention relates to a short message based location service method and a system thereof.

Currently, each mobile communication service provider provides a location search service using a mobile communication terminal. Latitude service is a service that can determine the current location of a friend or family to find through the current location of the mobile communication terminal.

Such a location search service is performed through a GPS system using satellites or a location of a user located in a specific cell using a base station. The tracked information is provided to the user who wants to find the other party.

That is, when the mobile communication terminal of the mobile communication subscriber is in a power-on state, it informs the mobile communication network of its current location, and the mobile communication network registers and manages the current location information of the mobile communication terminal in the home location register (HLR). The current location information of the mobile communication terminal registered in the home location register includes unique information of the base station responsible for wireless communication with the mobile communication terminal.

Therefore, the mobile communication network always knows which base station coverage the mobile communication terminal is in. In addition, mobile communication terminals incorporating GPS modules are currently being used. The GPS (Global Position System) module of the mobile communication terminal detects the current position of the mobile communication terminal by communicating with satellites and thus is more accurate than the range of the base station. Provide a location.

The friend-finding service of the mobile communication network has been proposed by the above-described technology for identifying the current position of the mobile communication terminal, and is a service that a large number of subscribers currently use. Unlike the general service, the friend finder service provides the subscriber with the information of the other person (the requestee), and thus requires the service agreement of the requestee. For this reason, the friend finder service consists of inquiring the requestee (tracker) 's service agreement to the requester (tracker) and providing the current location according to the query result.

1 is a flowchart illustrating a conventional friend search service providing process, briefly described as follows.

When the tracker requests a friend search service for the tracked mobile communication terminal after accessing the web server through the wireless Internet, that is, if the tracker requests location information of the tracked mobile communication terminal (ST1), A short message (SMS) for inquiring consent for the location information provision request is transmitted (ST2).

When the requestee receives the location information providing consent request SMS (ST3), the requester determines whether to agree to provide the location information after confirming the tracker's information from the received SMS, and if the user agrees to provide the location information (ST4), the SMS is included in the SMS. And accesses the friend search service server through the transmitted callback URL (ST5), and registers a password with the service server so that the current location is provided only to the tracker (ST6).

The service server informs the tracker of the password (ST7), and after the tracker inputs the password to request the location information of the tracked mobile communication terminal (ST8), the service information is sent to the tracked mobile terminal. Provided (ST9). If the requestee does not agree to provide location information, the service is not provided (ST10).

However, in the conventional method of providing a friend search service, the requestee must have a series of processes such as requesting the location tracking of the requestor or registering a password in the service server after accessing the service server through the wireless Internet for providing information. There is a problem in that it takes a lot of trouble and a lot of money, and it takes a lot of time for the informed consent process.

The requester terminal (1) is configured to request a location search after writing a text message including the telephone number of the requestee terminal (5) to find a location in the text message creation environment, home location register (10; HLR, VLR) ) Is configured to have the location information of the location coordinates or address of the subscriber in real time, the database 30 stores the information related to the location and location permission for each subscriber, the message center 50 is the requester terminal (1) After receiving the text message transmitted from the service provider determines the type of service, and automatically transfers the transmitted text message to the location search system 60, as well as the location information transmitted from the location search system 60 requester terminal (1) It is configured to transmit to the location search system 60, the location search system 60 is a message for the location request from the message center 50 is delivered to the database 30 After the search determines whether the requestee is registered in the location allowable state, and if the location is in the allowable state, it is configured to receive the current location information of the requestee through the home location register 10 and deliver it to the message center 50.

That is, by inputting the telephone number and the identification number of the service type of the requesting terminal 5 to find the location in the text message creation environment of the mobile communication terminal, and requesting the location tracking, a text message service familiar to the user (SMS) As it is easy to access and use only the phone number and identification number of the requested terminal (5), it is much easier to use, and there is a feature that can use the friend search service at a low cost.

The database 30 has a structure as shown in FIG. 3, wherein, for each subscriber, a friend list management area including information of friends who allow location tracking to the user, and information of other friends who allow the user to track location Included is a location management area, and a service management area for blocking the location of the person or change the password to all the opponents for a certain period of time.

In addition, the text message is created and transmitted in the requester terminal (1) has a format as shown in Figure 4, as shown, the identification number indicating the location service (TI; Telephony Identifier or TID; Teleservice Identifier) and requester And a telephone number of the terminal 1, a telephone number of the requestee terminal 5, and a command.

Among the text message formats, a user directly inputs a command as shown in FIG. 5, and commands are different for each function, and it is natural to add or change a command as necessary.

Looking at the functions of the friend-finding service and the command according to the function as shown in Figure 5, first find the relative position by the address in the find / transfer items (command: Blank or 'location'), the relative position to the map (command) : "Map"), Find your location by address (party number: your phone number, Command: Blank or 'Location'), Find your location by map (Command: 'Map'), Send your location address (Command: 'My Location' or 'My Address'), and Send My Location Map (Command: 'My Map').

Also, in the Friends list management item, you can add a friend who has allowed you to Latitude (Command: 'Add'), Delete a friend who has been disallowed Latitude (Command: 'Delete'), View friend list (Command: 'List' ), And the My Location Management item adds a friend who allows you to track your location (command: 'allow' and password), and deletes a friend who cancels your location tracking (command: 'allow delete 'And password), a list view that allows you to track your location (command:' allowed list 'and password), and a list view (command:' query 'and password) that searches your location tracking. have.

And, in the service management items, the dive setting (command: 'submersion' and password), the submergence (command: 'release' and password) to revoke the permission of the user's Latitude to all parties for a certain period of time, change the current password It consists of functions and commands such as changing password (command: 'password') and requesting termination of request for termination of friend search service (command: 'termination').

Characters in quotes ('string') in the command is a string command directly input by the user on the text message menu screen, but it is natural that the command can be changed according to design.

6A and 6B are procedural diagrams illustrating a general process of performing a friend location search service according to FIG. 2, which will be described below with reference to FIGS. 2 to 7.

First, the database 30 stores subscriber information including the phone number, the resident registration number and the password of the subscriber terminal (1, ..., 5) and information related to the location tracking permission of the user and the friend (S1). .

In this state, the requester accesses the text message creation environment installed in the requester terminal 1, and transmits the text message including the telephone number of the requestee terminal 5 to find the location (S2).

For example, after accessing the text message creation page through the short message creation menu, enter a service identification number '7979' in the reception number input field as shown in FIG. 7A, and at least one or more characters in the text message writing window as shown in FIG. 7B. A text message is created by inputting the telephone number (01080804209) of the requestee terminal 5 and the character string 'location', which is a location tracking command, or by setting it as 'Blank'. Of course, the service identification number 79 and the telephone number (01080804209) of the requested terminal 5 are simultaneously input ('7901080804209') to the reception number input field as shown in FIG. 7A, and the next page is as shown in FIG. 7B. In the text message writing window, you can write a text message using the location tracking command 'Location' or 'Blank'.

When the phone number of the plurality of requestee terminals is input in the text message writing window, the location of the plurality of persons is inquired simultaneously.

Since the reception number input window and the text message writing window are set differently for each manufacturer of the terminal, the relationship between before and after may be ignored. In addition, when inputting the telephone number and the command of the requested terminal 5 in the text message writing window at the same time as shown in Figure 7b it is preferable to distinguish from each other using a comma (,) or a blank (Blank).

If, instead of inputting the telephone number of the requestee terminal 5 in the text message writing window, the user can receive an address according to his / her current location by inputting his / her telephone number.

The text message thus prepared is in the form of a data format including a service identification number, the telephone number of the requesting terminal (1), the telephone number of the requesting terminal (5), and a command. (S3), the message center 50 determines the type of service through the identification number (eg, '79' or '7979') included in the text message, and delivers the text message to the location search system 60. (S4).

The location search system 60 searches the database 30 according to the telephone number of the requester terminal 1 included in the text message to determine whether the requester terminal 1 is subscribed to the friend search service. That is, the location search system 60 transmits the phone number of the requester terminal 1 included in the text message to the database 30 to request the search for subscription, and the database 30 calls the telephone of the requester terminal 1. After searching for a subscription using the number, the result is transmitted to the location search system 60 (S5 to S7).

If the requester terminal 1 is not subscribed to the friend search service, the location search system 60 requests the message center 50 to guide the subscription to the requester terminal 1 and the message center 50. ) Will generate a callback text message (WAP Push) for authentication of the requester's subscription as shown in FIG. 7C and transmit it to the requester terminal 1 (S8, S9).

Subsequently, the requester accesses the location search system 60 through the wireless Internet (WAP) through a text message for callback when a subscriber wants to join as a service member, and then obtains personal information and password such as the resident registration number of the requestor as shown in FIGS. 7D to 7F. Enter sequentially to join the service use member (S10).

The member information input as described above is transferred to the database 30 and stored and managed for each subscriber, and the database 30 transmits a subscription confirmation signal to the location search system 60 (S11 to S13).

On the other hand, if the requester is subscribed as a service member, the location search system 60 requests the search through the database 30 whether the requestee is allowed to track the location using the phone number of the requested terminal (S14). . Subsequently, the database 30 searches the requester's friend list management area to inquire whether the requestee is registered as a friend list and allows the location tracking status, and then transfers the result to the location search system 60 (S15 and S16). . If the friend previously allowed the user to track his location, the friend's terminal number is automatically registered in the requester's friend list management area.

If the requestee is not registered in the friend list management area of the requester, the location search system 60 notifies the message center 50 that the requestee is not allowed to track the location (S17). Accordingly, the message center 50 prepares a callback text message (WAP Push) requesting permission of the requested location tracking as shown in FIG. 7G and transmits it to the requestee terminal 5 (S18).

Subsequently, the requestee accesses the location search system 60 through the wireless Internet (WAP) through a text message for callback and inputs the requestee's password as shown in FIGS. 7H and 7I to allow the requester to track the location ( S19). Of course, when the requestee is not subscribed to the service, a password is assigned by registering as a member through a process as shown in FIGS. 7C to 7F.

As described above, when the requester allows his / her location tracking, the location search system 60 adds and stores the telephone number of the requestee terminal 5 in the friend list management area of the requester database 30 to request later. If the self wants to know the location of the requestee, the requester provides the requestor with the location of the requestor without requesting permission for location tracking (S20-S22).

If the requestee is allowed to track their location as described above, the location search system 60 requests the location information of the requestee to the home location register 10 (S23), and the home location register 10 The location information of the requestee held in real time, that is, the address according to the location is inquired and transmitted to the location search system 60 (S24 and S25).

Accordingly, the location search system 60 transmits the location information to the message center 50 (S26), and the message center 50 transmits the location information to the requestor terminal 1 using the text message service (S27). In operation S28, the requestor terminal 1 displays the address according to the requestee's position as text as shown in FIG. 7J.

6A and 6B, the procedure indicated by the dotted arrow is a procedure for requesting the requester's or the requester's membership and the requestee's location tracking permission, which is performed when the location tracking service is initially used between the requestor and the requestee. Therefore, if the requestor and the requestee are already subscribed as service members or allow mutual location tracking, the procedure indicated by the dotted arrow is omitted.

FIG. 8 is a user interface showing a function for sending a location. The service number is entered into a received number input field as shown in FIG. 8A, and a 7979, which is the next page. If you enter the phone number (01080804209) of the terminal 5 and the text string "My location" which is a command to send my location to create and send a text message, the location search system 60 sends its location information to the other party. Therefore, without performing the location tracking permission confirmation procedure to the requester, it is possible to immediately obtain the address information according to the location through the my location verification procedure as shown in Figs. 6a and 6b and transmit to the requester terminal 5 as shown in Fig. 8c. . Checking the location information through the home location register 10 is the same as in FIGS. 6A and 6B and thus will be omitted.

9 is a schematic diagram illustrating a location search system for finding a friend's location using a mobile communication network according to another embodiment of the present invention. The requester terminal 1, the home location register 10, the GIS server 20, and a database ( 30), the SMS center 50, the location search system 60 and the MMS center 70 and the like.

The requester terminal (1) is configured to request a location search after creating a text message including the phone number and map request information of the requestee terminal (5) to find a location in the text message creation environment, the home location register (10) ; HLR, VLR) is configured to have real-time location information about subscriber's location coordinate or address, GIS server (Geographical Information System Server) 20 contains map information by region (address), and database ( 30) stores the information related to the location and location allowance for each subscriber, SMS center 50 receives the short message sent from the requester terminal (1) to determine the type of service and then sent the short message sent to the location search It is configured to deliver to the system 60, the location search system 60, if the message for the location request from the SMS center 50 is delivered, the database (3) 0) is searched to determine whether the requestee is registered as the location allowed state. If the location is in the allowed state, the current location information of the requestee is provided through the home location register 10, and the map data according to the location information is obtained from the GIS server. 20, the MMS center 70 receives the map information from the location search system 60, converts the map information into a form suitable for the terminal, and transmits the requested map information to the requesting terminal 1; Consists of.

In other words, by inputting the telephone number and the identification number of the service type of the requesting terminal (5) to find the location in the text message creation environment of the mobile communication terminal, and requesting the location tracking with the map information, a friendly text message service from the user's point of view As it is easy to access and only need to enter the telephone number and service identification number and the map request command of the requestee terminal (5) is much easier to use, there is a feature that can use the friend search service at a low cost.

The database 30 has a structure as shown in FIG. 3, and the text message created and transmitted in the requester terminal 1 has the format as shown in FIG. 4. There are the same as in Figure 5, which is the same as the above embodiment so that a separate description will be omitted.

FIG. 10 is a flowchart illustrating the overall process of the friend location search service according to FIG. 9. Referring to FIGS. 9 to 11, FIG.

First, the database 30 stores subscriber information including phone numbers, social security numbers, and passwords of subscriber stations 1, ..., 5 and information related to the location tracking permission of the user and friends (S31). .

In this state, the requester accesses the text message service menu installed in the requester terminal 1, and transmits a text message including the telephone number of the requestee terminal 5 to find a location (S32).

For example, after accessing the text message writing page through the short message writing menu, enter the service identification number '7979' in the receiving number input box as shown in FIG. 11A, and the requested terminal in the text message writing window as shown in FIG. 11B. (5) Input the phone number (01080804209) and the string "Map" which is a map search command to create a text message. Of course, the service identification number 79 and the telephone number (01080804209) of the requested terminal 5 are simultaneously input ('7901080804209') into the reception number input field as shown in FIG. 11A, and the next page is as shown in FIG. You can also write a text message by entering the string 'Map' which is a map search command in the text message writing window.

Since the reception number input window and the text message writing window are set differently for each manufacturer of the terminal, the relationship between before and after may be ignored. In addition, when inputting the telephone number and the command of the requestee terminal 5 in the text message writing window at the same time as shown in Figure 11b it is preferable to distinguish from each other using a comma (,) or blank (Blank).

The text message thus prepared is SMS via the mobile switching center 40 in a data format including a service identification number, the telephone number of the requesting terminal 1, the telephone number of the requested terminal 5, and a command ('map'). Transfer to the center 50 (S33), SMS center 50 is a text message created after identifying the service type through the identification number (for example, '79' or '7979') included in the text message location search system ( 60) (S34).

The location search system 60 searches the database 30 according to the telephone number of the requester terminal 1 included in the text message to determine whether the requester terminal 1 is subscribed to the friend search service (S35 ~). S37).
