Description

How to provide friend search service using SMS {Method for providing sevice of user location information using Short Message Service}

The present invention relates to an additional service of a mobile communication network, and more particularly, to a method of providing a friend search service for providing a current tracker's current location to a tracker based on current location information of a mobile terminal.

In general, when a mobile terminal of a mobile communication subscriber is in a power-on state, the mobile terminal notifies its current location to the mobile communication network, and the mobile communication network registers and manages the current location information of the subscriber mobile terminal in the home location register (HLR). The current location information of the mobile terminal registered in the home location register includes unique information of the base station responsible for wireless communication with the mobile terminal. Therefore, the mobile communication network always knows which base station coverage the mobile terminal is in. In addition, the mobile terminal with a GPS module is widely used. The GPS (Global Position System) module of the mobile terminal detects the current position of the mobile terminal through communication with a satellite and provides the position of the mobile terminal more accurate than the range of the base station. .

The friend-finding service of the mobile communication network has been proposed by the above-described technology for identifying the current location of the mobile terminal, and is a service that a large number of subscribers currently use. Unlike the general service, the friend search service provides information of another person (the tracee) to the subscriber, and therefore, the consent of the tracee's service is required. For this reason, the friend finder service consists of querying the tracee's service agreement to the tracker and providing the current location according to the query result.

Referring to Figure 1 briefly described a conventional method for providing a friend service as follows. When the tracker requests a friend-finding service for the tracked mobile terminal, that is, when the tracker requests the location information of the tracked mobile terminal (S101), a short message for inquiring consent of the tracker's location information provision request to the tracked mobile terminal ( SMS) is transmitted (S102).

When the tracee receives the location information providing consent request SMS (S103), after checking the tracker's information from the received SMS, the tracee decides whether to provide the location information, and when agreeing to provide the location information (S104), the SMS is included in the SMS. Then, the user accesses the friend search service server through the transmitted call back (Uniform Resource Locator) URL (S105), and registers the password with the service server so that the current location is provided only to the tracker (S106).

The service server informs the tracker of the password (S107), and after the tracker inputs the password to request the location information of the tracked mobile terminal (S108), the tracker provides the location information of the tracked mobile terminal to the tracking mobile terminal ( S109). If the tracee does not agree to provide location information, the service is not provided (S110).

However, in the conventional method of providing a friend search service, the tracee has to take a series of processes such as accessing the service server and registering a password in the service server to provide information, and have to take the hassle and cost, and agree to provide the information. There is a problem that takes a lot of time for the process. In addition, unless the tracee's registered password is changed separately, the tracer can search the tracee's location indefinitely. There is a problem of staying within range.

In addition, the conventional friend search service can only look up one person at a time, it is provided based on the text (text), so the simultaneous implementation of multiple location lookup function and multimedia-based friend search function desperately needed Required.

The present invention for solving the conventional problems is to simplify the process of obtaining the agreement for providing the location information between the tracker and the tracee to reduce the burden on the use of the tracee's service and to provide one-time or limited location information For the purpose of It is also an object of the present invention to enable the tracker to look up a number of locations in one query.

The present invention for achieving the above object is a method for providing a friend search service in a friend search server providing a friend search service, when receiving a friend search service request including a tracer's telephone number from the tracker, the friend search server Requesting, by the SMSC, that the first message for requesting consent to provide location information is transmitted to the tracee, and the response message of the first message including the response content of the tracee by the friend search server is sent from the SMSC. A second step of receiving, a third step of confirming the response contents of the tracee by reading a specific field of the received response message by the friend finder server, and the response contents confirmed in the third step provide location information If allowed, register the traceee's location information permission condition value for the tracker included in the received response message. A method of providing a friend finder service including a fourth step of providing a tracker with current location information of a tracked mobile terminal is provided.

In order to achieve the above object, the present invention, when receiving a friend search service request including a tracee's phone number from a tracker in a computer connected to an IP network, the friend search server requests a position information provision agreement to the SMSC. A first step of requesting a message to be sent to the tracee, a second step of the friend search server receiving a response message of the first message containing the response of the tracee from the SMSC, and the friend search server Reads a specific field of the received response message and confirms the response contents of the tracee, and if the response contents confirmed in the third step are to provide location information, the response message included in the received response message is included in the received response message. Register the tracker's allowance value for the tracker and provide the tracker with the current location information of the tracked mobile terminal. Is provided a recording medium readable by the computer program is recorded for executing the fourth step.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of related well-known functions or configurations will be omitted when it is determined that they may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

Hereinafter will be described the configuration of a communication network for the service of the present invention. 2 is a block diagram of a service network according to an embodiment of the present invention. The service network of the present invention is provided with a conventional mobile communication network 10 for mobile terminals (M1, M2), and enables the exchange of short messages between mobile terminals (M1, M2) via the mobile communication network (10). Short message service center (SMSC) is provided for transmitting the short message in response to the short message transmission request of the friend search server 40 via the Internet network 20.

The friend search server 40 controls the overall operation of the friend search service and performs data communication with the mobile terminals M1 and M2 and the SMSC 30 through the Internet network 20 and the Internet network 20. It includes a GIS server 50 for providing a geographic information system (GIS) to the mobile terminal (M1, M2) to the mobile terminal (M1, M2) via the media.

In this case, the mobile terminals M1 and M2 may have a GPS function, and in this case, the current position (current position coordinates) of the mobile terminals M1 and M2 calculated using the GPS module at the request of the friend search server 40. ) Is provided to the friend search server 40. In addition, the mobile terminals M1 and M2 may include a virtual machine to display map information received from the GIS server 50 and the current location of the mobile terminals M1 and M2 on a graphic screen.

Hereinafter, an embodiment of the present invention for providing a friend search service for one tracee will be described with reference to FIGS. 3 to 6.

For the friend-finding service of the present invention, it is necessary for the service requester (ie, the tracker) to request the provision of the location information to the target person (ie, the tracer) of the location information and obtain consent. Therefore, the process of requesting the tracee to provide the location information and obtaining the result will be described with reference to FIG. 3 through the operation of the tracee mobile terminal.

When the tracker connects to the friend search server 49 and requests the location information providing the tracee's phone number, the friend search server 40 sends the SMSC 30 the location information provision consent request SMS to the tracker request. Requires. Accordingly, the tracked mobile terminal M2 receives an SMS message for requesting location information consent from the SMSC 30 (S301).

In this case, the location information providing consent request SMS message is a TI interval in which a telephony identifier (TI), which is a code indicating that the SMS message for requesting location information provision, is recorded among SMS messages for a friend search service, as shown in FIG. 5. And an MIN section in which a mobile identification number (MIN) of the tracking mobile terminal is recorded, a query text section in which a query text for querying location information provision agreement is recorded, and a consent / deny for location information provision It contains the optional fingerprint section to be recorded. The TI section, the MIN section, the query text section, and the optional fingerprint section are included in the CHARi field of the SMS message. The SMS of the present invention is a data burst message (DBM) conforming to the protocol of IS-95-A.

Upon receiving the location information provision consent request SMS as described above, the tracked mobile terminal M2 checks the TI to confirm the message type, and then displays the CHARi field of the received SMS on the screen (S302). The contents of the CHARi field displayed at this time are as shown in FIG.

In Figure 4, the screen of the tracking mobile terminal "0112345678" is displayed on the screen, the query "The user has requested to provide location information. Do you want to accept" is displayed, "1. Only once, 2. "* Allow for [*] hours, 3. Continue to allow, 4. Do not allow" is displayed.

As described above, when the request information for providing location information is displayed on the screen of the mobile terminal M2, the tracee decides to allow or deny, and whether to allow only one time in allow or only allow for a specific time, Or decide whether to continue. The tracee who has made this decision selects one from the inquiry fingerprints (S303).

In this case, if the traced mobile terminal M2 continues to allow the traced (S304), as shown in FIG. 4, the password input of “1. Use existing password, 2. New input [****]” is entered. By displaying the guide text for requesting the tracee input password (S305), and obtains (S306).

On the other hand, when the tracee selects a choice fingerprint other than the continuous allowance in step S403, the response DBM is generated in which the content of the choice fingerprint selected by the tracee is recorded in an appropriate format in the CHARi field (S307). The tracked mobile terminal M2 continues the process (S307) even after acquiring the password (S306) according to the permission.

 An example of the DBM generated in step S307 is shown in FIG. 5. Referring to FIG. 5, the DBM may additionally be added by the tracee, such as a TI section indicating that the message type is a response, a MIN section in which the phone number of the tracking mobile terminal is recorded, a selection number section in which the selected fingerprint number is selected by the tracee, and a password. And an option information section in which the input option information is recorded. The option information may include various information required for a service in addition to a condition value such as a password or a location query allowable time.

When the trace mobile terminal M2 generates the response DBM, it transmits it to the SMSC 30, and the SMSC 30 transmits the received response DBM to the friend search server 40 (S308).

Through the above-described description, the tracee notifies the friend search server 40 of his intention in accordance with the request for providing position information for the tracker. Thereafter, the friend finder server 40 notifies the tracer of the information providing intention of the tracee and provides a friend finder service accordingly.

Hereinafter, the operation of the friend finder server 40 of the present invention will be described with reference to FIG. 6.

When the tracker presses a hotkey for requesting a friend search service formed on the tracking mobile terminal M1, a data call path is set between the tracking mobile terminal M1 and the friend search server 40, and the tracking mobile terminal M1 is a friend search server. 40 is connected. In this state, the tracking mobile terminal M1 connects to the friend search server 40 and requests the location information while providing the phone number of the tracked mobile terminal M2.

When the friend finder server 40 receives the location information providing request from the tracking mobile terminal M1 (S601), the phone number of the tracked mobile terminal M2 is provided to the SMSC 30 while the above-described FIGS. In order to perform the same operation as described above, the contents to be recorded in the CHARi field of the SMS are appropriately configured to transmit the SMS for requesting the provision of the location information to the tracked mobile terminal M2 (S602). The SMSC 30 transmits an SMS for requesting consent to provide location information to the traced mobile terminal M2.

Thereafter, the SMSC 30 receives the response DBM for the location information provision consent request SMS from the tracked mobile terminal M2 and provides it to the friend search server 40.

When the friend finder server 40 receives the response DBM from the SMSC 30 (S603), the friend search server 40 searches the selection number section in the CHARi field of the response DBM to determine the response of the tracee (S604).

If the friend search server 40 determines that the tracee does not allow the provision of the location information through the determination (S604) for the response number section (S605), the trace mobile terminal (M1) informs the tracee of the denial of service. The message is transmitted and the friend search service for the tracee is not provided (S606).

On the other hand, if the friend finder server 40 determines that the tracee has provided the location information through the determination (S604) for the response number section (S605), if the continuous location information provision is allowed (S607), The password recorded in the selection option information section of the response DBM is registered by matching the unique information of the tracee (S608), and the tracking mobile terminal M1 is notified of the password (S609). When the friend trace server 40 receives the tracer's password from the tracking mobile terminal M1 (S610), the friend finder server 40 performs the following step S612.

On the other hand, if the friend finder server 40 determines that the tracee has provided the location information only once in the determination (S606), the friend finder registers the allowable number to match the unique information of the tracee, and the tracee in the determination (S606). If it is determined that the provision of the location information for a specific time only matches the unique information of the tracee and registers a specific time (S609).

When the specific time is registered as described above, the friend search server 40 drives the timer in response to the tracker, and when the timer reaches the registered specific time, the friend search server 40 releases the registration of the tracee's provision of permission to the registered tracker. And for a specific number of times, the tracker requests a friend search service and counts the number of times, and when the specific number of times, the registered location information provision permission is released.

When registering the location provision allowance for the tracee, friend search server 40 is obtained by requesting the current position of the tracked mobile terminal M2 from the home location register (S610), if necessary to the GIS server 50 After acquiring map information corresponding to the current location of the acquired tracked mobile terminal M2 (S611), the current location information of the acquired tracked mobile terminal M2 and the map information corresponding to the current location information are obtained. The transmission is transmitted to the tracking mobile terminal M1 (S612).

Here, the present invention has been described that the friend search server 40 requests and obtains the map information from the GIS server 50 in the above-described process (S612), and the tracking terminal directly requests and obtains it from the GIS server 50. Can be implemented. At this time, the tracking terminal M1 obtains the map information by providing the current location information of the tracked terminal to the GIS server 50.

When the map information and the location information of the tracked mobile terminal M2 are acquired as described above, the tracking mobile terminal M1 displays the map information as graphic information on the screen through a built-in virtual machine, and displays the displayed map. The tracee's name or avatar is indicated on the range corresponding to the positional information of the traced mobile terminal M2 on the screen.

Here, when the tracked mobile terminal M2 has a GPS function and the tracking mobile terminal M1 requests the provision of GPS-based location information, the friend finder server 40 may request a mobile terminal from the tracked mobile terminal M2. The GPS-based current location information of the M2 is received and provided to the tracking mobile terminal M1. After all, according to the GPS-based location information of the tracked mobile terminal M2, the trackee's location is displayed on a screen of the tracked mobile terminal M1 at a specific point (coordinate) on the map information.

Through the above description, the present invention notifies whether the tracee agrees to provide the location information by using the DBM message according to the tracker's request for friend search service, and registers a password after the tracked mobile terminal accesses the friend search server. You do not have to go through the cumbersome process.

In addition, due to the operation of acquiring the location providing agreement of the present invention and the operation of the friend search server, the present invention can simultaneously obtain location information on a plurality of traceees, which could not be implemented in the related art, and provide the same to the tracking mobile terminal. Therefore, when the tracking mobile terminal requests a friend search service by grouping a plurality of traces into a group, the tracking mobile terminal can simultaneously display the positions of the plurality of traces on one screen.

As described above, the current location of the plurality of traceees is displayed on the map as shown in FIG. 7 on the screen of the tracker provided with the friend-finding service of the present invention which provides the location information of the plurality of traceees. In FIG. 7, each tracee is displayed as an avatar, and when an avatar is clicked, optional functions such as dialing, SMS transmission, MMS connection, and GPS-based location information can be selected.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

The present invention receives the result of whether or not the tracee provides the location information for the tracker's consent to provide the location information by using the DBM signal, so that the tracee's consent to provide the location is not required because the tracee does not need to access the friend search service server. It is simplified and has the effect of allowing the tracee to provide limited location information to the tracker.
