Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a location inquiry and a security service method for a mobile communication terminal having a GPS,

The present invention relates to a location inquiry and a security service method using a mobile communication terminal equipped with a Global Positioning System (GPS), in which when a guardian terminal requests location information of a protected terminal from a server, And transmits the obtained location information to the guardian terminal to inform the guardian of the current location information of the protected terminal.

Recently, there has been proposed a so-called care service that combines IT technology, especially mobile communication terminal technology, with the social welfare fields such as child crime prevention, elderly people, and persons with disabilities, as well as traffic accidents. For example, in Korea, SK Telecom provides "anecare service" using a mobile terminal dedicated to the service for seniors living alone in the Seosan area, so-called "U-care service" Is a welfare service implemented by the elderly people aged 65 or older. It refers to a new concept of security service, which is used to check the safety by using a remote electronic control system and to quickly rescue when an emergency occurs .

At present, as an additional service provided by the applicant "iSearch service" (KT (Katy), if the parent mobile phone number corresponding to the application of the iSearch service is registered in the KT server, (Eg, a service that notifies the parent cell phone every hour or sets a safe area so that the parent cell phone can check the entry and exit of the child in the area). In this case, , Child's mobile phone) to the caregiver. In addition, a service for allowing a child to be notified of the position of a child by a setting cycle by setting a predetermined time period has been conventionally provided, and a safety zone (a specific area selected by the guardian) is set, A service for allowing a guardian to receive a text notification when a child enters or exits an area set as a relief zone is provided as a prior art.

However, in the case of the iSearch service method, since the mobile terminal is based on a mobile phone base station rather than a satellite detection function, it detects a location based on a mobile phone base station near a child rather than a precise position such as a navigation, , There is a problem in that there is a limit to precisely grasp the positional information of the person to be protected. Also, since the service itself is used as a location data inquiry purpose, there is a problem that the necessity for a normal service is deteriorated.

Also, in the case of an elderly person or a handicapped person having difficulty in handling a mobile communication terminal such as a mobile phone or a smart phone, even if the terminal is possessed, it is difficult to change the setting by mistake or manipulate in an emergency, There were many cases where I did not receive the substantial benefits of security services like Ise search.

Accordingly, the present invention provides a function for a guardian to remotely control the function setting of a protected terminal for a vulnerable layer (for example, a sick person, a disabled person, etc.) in which a mobile phone is not easily operated, It is aimed to provide location inquiry and security service for children, the elderly, etc. by making a call to the guardian through the video call function or making contact with the security dispatcher's affiliate call center.

The present invention relates to a location inquiry and a security service method using a mobile communication terminal having a GPS, the method comprising: requesting location information of a protected terminal from a guardian terminal to a server; The server receiving the request transmits a USSD message to the protected terminal having GPS to activate real-time location positioning; Receiving the USSD message, performing a position location operation to obtain location information of a protected terminal, and transmitting the obtained location information to the server; The server transmitting the transmitted location information to a guardian terminal; And displaying the location information received from the server on the parent terminal.

In addition, the protection target terminal includes an emergency button, and when the emergency button is activated, the protection target terminal forcibly activates the real time location positioning even if the USSD message is not transmitted, And transmits location information to the server together with the emergency status message and transmits the emergency status message and the current location information received by the server to the guardian terminal. When the emergency button is activated, the protection target terminal may transmit an emergency notification sound to the outside, and may also take an on-site picture or perform an automatic video call function with a guardian.

Further, the guardian terminal and the protection target terminal have a dedicated application for implementing the service, and when the setting of the application is changed in the guardian terminal remotely located from the protection target terminal, And the server transmits the change information to the protection target terminal, automatically synchronizes the application setting of the protection target terminal, and stores the changed setting according to the synchronization.

The present invention improves the inaccuracy of the position information of the target terminal to be positioned, which is the target of positioning, by using the GPS, and improves the accessibility and necessity of the service by providing the dedicated application to the general guardian mobile phone . Also, when using USSD method using WCDMA wireless communication network, transmission speed is up to 7 times faster than SMS because it is not a post-storage method.

Accordingly, the present invention provides features such as accurate location information, emergency alarm sound, automatic video call with a guardian, and transmission of a picture on the spot, thereby preventing accidents through quick dispatch, There is an effect.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In an embodiment of the present invention, USSD (Unstructured Supplementary Service Data) message transmission method using WCDMA (Wideband Code Division Multiple Access) method is taken as an example, but CDMA Access) based short message service (SMS) message. The USSD method is a means for transmitting information or a specific command from a WCDMA wireless communication network. Unlike the SMS service, the USSD method is a communication path setting / canceling method like a data service instead of a post-storage transmission method. Also, it can be implemented as a multimedia messaging system (MMS) including a photo, a moving picture, and a voice using a 3G mobile communication network in addition to the USSD.

Figure 1 illustrates the service method of the present invention through inter-component operations and procedures. The system 1000 according to the present invention includes, for example, a guardian terminal 100, a server 200, and a protected terminal 300. The guardian terminal 100 and the protection target terminal 300 may be a mobile phone having a GPS module, a 3G mobile communication network access function, a USSD message processing capability, a LBS (location based service) personal digital assistants, smart phones, tablet PCs, laptops, personal computers, and the like. More specifically, the parent terminal 100 may be a smart phone or an application running on a computer. Also, the server 200 is a dedicated server according to an embodiment of the present invention having a terminal authentication function, a subscriber change information collection function, a location history management function, and the like.

1, when the guardian terminal 100 wants to know the location of the protected terminal 300, it uses the application of the protected terminal 300 to transmit the location information to the server 200 Can be requested. The application can be a computer application or a smartphone application according to the terminal 100 or 300 of the present invention as a dedicated application program according to an embodiment of the present invention. The server 200 receiving the request requests the USSD message to activate the real-time location of the GPS to the protected terminal 300 having the GPS. Here, USSD is a means for transmitting specific information or commands using a GSM (Global System for Mobile communications) network. There are two modes, MMI (Multi Model Interface) mode and Application mode. Character string to the network, or conversely, to send a string to the user terminal from the network. Application mode USSD is used for data transmission between the network and the terminal. WCDMA is a CDMA-based technology, but it is a third-generation communication technology developed in GSM, and it is asynchronous, so it is compatible with GSM and USSD service is available. Also, the positioning technique refers to a technique of using the GPS or utilizing the base station position of the wireless network to grasp the exact position of the service request terminal.

The protected terminal 300 receiving the USSD message from the server activates the location location, acquires the location information thereof, encrypts the location information, and transmits the encrypted location information to the server 200. The server 200 receiving the encrypted location information from the protected terminal 300 transmits the location information to the protected terminal 100 again.

The protected terminal 100 may display location information received through the application using a content such as a text message, a photograph, or a map on the screen of the parent terminal 100. Even when the protected terminal 300 is a computer, it is possible to receive position information using a network (e.g., the Internet) and display the position information using an application.

Unlike the cell positioning method using the existing cell phone base station, the present invention is effective in that the accurate position of the protection target can be grasped without using the base station by using the GPS having the satellite detection function have.

Figure 2 shows a concrete real-time location positioning step using a USSD message. 2, when a real-time location inquiry is requested on a guardian terminal or a computer network (e.g., Web) 100, the service server 200 requests a gateway server 250 to transmit a USSD message, The gateway server 250 in cooperation with the server 200 can transmit the USSD message to the protected terminal 300 to activate the real-time location inquiry and positioning. Here, the gateway server 250 has a function of converting the protocol between a plurality of communication networks having different protocols and transmitting / receiving information, and receiving the encrypted location information from the protected terminal. In this description, the operation of the gateway server 250 will be omitted, and the functions and procedures of the components will be described by including them in the function of the server 200 as occasion demands. However, it goes without saying that the gateway server 250 may be physically integrated with or separated from the service server 200.

FIG. 3 is a flowchart illustrating a method of performing location positioning in a protected terminal receiving a USSD message. Before the protection target terminal receives the USSD message of the location location request from the server, the protection target terminal 300 stores the final location location information, that is, the final location information.

When the USSD message is received, the positioning is activated. First, the activity check sensor mounted on the protection target terminal 300 determines whether the terminal is active or not. The activity amount check sensor is a sensor mounted on the protection target terminal 300 and sensing movement of the protection target. When it is determined that there is no movement of the protection target terminal after the determination, the final position information is transmitted to the server as the position determination result.

However, when it is determined that there is movement of the terminal, it is necessary to determine whether or not the GPS positioning is possible. When the GPS positioning is possible, the A-GPS (Assisted-Global Positioning System) positioning is performed and the position information obtained through the positioning is transmitted to the server. Here, A-GPS is a positioning technology in which a chip embedded in a terminal reads position information sent from a satellite. Even if a GPS satellite is used, the accuracy and usability of the A- The location of the terminal is measured by mixing location information sent from the terminal and information generated at the base station.

 On the other hand, if the GPS positioning is impossible, the mobile station requests a cell positioning to the server, receives the result of the request, stores the result in the protection target terminal, and retransmits the result to the server. As described above, the cell positioning is a type in which the nearby cellular base station detects the current position when the GPS positioning is difficult and the current position of the base station is notified to the guardian terminal.

In this way, according to the present invention, when there is no movement of the protected terminal or real-time GPS positioning is used as compared with existing positioning services, quick positioning and accurate position information can be provided And it is possible to perform the cell-based cell positioning even if the real-time GPS positioning fails, and to provide the result quickly.

FIG. 4 illustrates a method of periodically notifying a location in a service method of the present invention. The guardian terminal 100 may request the location information of the protected terminal 300 to the server 200 through a predetermined time period (e.g., time, day of week, etc.) through the application of the guardian terminal 100 Can be set. By periodically requesting the location information according to the set period, the protected terminal 300 can perform the real-time location positioning and transmit the location information according to the algorithm described in FIG.

For example, referring to FIG. 4, a guardian may set a time at which a protected object is separated from a guardian (for example, a time at which the child is in school and a time at which the parent is at work) You can set the function to be notified.

The guardian terminal 100 automatically receives periodic location notification and can notify the location of the terminal through the cell positioning in the server 200 automatically when the protected terminal 300 does not report the location. Specifically, as shown in FIG. 4, the guard terminal requests updating of the position notification every cycle, and the server 200 receiving the request transmits a USSD message to the protection target terminal 300 , The periodic time is set in the same manner as the period set by the guardian terminal in the application of the protection target terminal, and the position determination is performed every set period and the position information of the protection target is transmitted.

FIG. 5 shows a function of notifying whether or not the relief zone is detached, in relation to the periodic position information notification. The guardian can set a specific number of areas or buildings (for example, three, houses, schools, academies) in the application of the protected terminal. When setting the specific area or building, a 'safety zone' is automatically designated within a radius of 2 km, for example, at a designated position on the map. Therefore, the relief zone refers to the area within a certain radius from the area or distance set by the guardian. The radial distance may be changed at the request of the guardian.

The guardian terminal 100 requests update of the location information of the protected object in the set period as shown in FIG. The server 200 receives the request, transmits the USSD message to the protection target terminal 300, sets the same period as the protection terminal, and also sets the security zone designation to be the same. Therefore, according to the setting, the protection target terminal 300 performs position determination every set period to determine whether it is located in the security zone. The protection target terminal transmits location information including the security zone detachment to the server 200, and the server transmits the received information to the guardian terminal 100. When leaving, the location information including the alarm message can be sent. In one embodiment, if the protected terminal 300 does not leave the safe zone, the location information may not be notified.

In case of children or elderly people, since the living radius does not deviate greatly from the house level, most of the terminals to be protected will be located in the safe zone. When leaving, the alert message can be notified to the guardian in the form of letters, pictures, etc. using vibration, a buzzer, a lamp, etc., and when the position is departed, the positional positioning can be implemented to operate in a shorter period (e.g., 5 minutes or 10 minutes) It will be possible. In this implementation, the service further includes a function of allowing the server to transmit the configuration data of the protector to the protection target terminal, and in case of the protection target terminal, the server should be provided with a function of determining whether or not the protection zone is detached. Alternatively, the server may receive the location information and determine whether the secure zone is deviated or not, and may transmit the determined result to the guardian terminal.

FIG. 6 illustrates an action of the emergency terminal in the protection target terminal. The protection target terminal 300 may have an emergency button prepared for an emergency. The emergency button can be implemented, for example, to be operated when the user depresses the button for a long time or presses the button more than once continuously. When the emergency button is pressed, the protection target terminal 300 can transmit a notification sound (e.g., a siren, a whistle sound, and the like) for informing the outside of the emergency to guide the other party to run away or notify the surrounding people of the dangerous situation Crime prevention is effective.

In addition, when the emergency button operates, a photograph can be automatically photographed using a camera equipped with the protection target terminal automatically at a time when a beep sounds or after a few seconds, and position information can be obtained by performing positional positioning. Then, the photographed photograph and the location information are transmitted to the server, and the server stores the photograph, determines the correct address through the photograph and the location information, and sends the registered registered guard and / Message format. In one embodiment, a short message including an indication that the emergency button has been operated together with the photographed image may be automatically transmitted to the guardian and / or a registered security company dispatch company control center or the like. In addition, after the message is transmitted, the video call function may be automatically activated and transmitted to the guardian. Through this function, the above-mentioned guardian can make a quick and accurate perception and judgment by talking to the person to be protected.

7 shows a procedure for controlling the functions of the protection target terminal 300 by transmitting application setting data of the guardian terminal 100 to the protection target terminal. It is necessary to remotely control the operation of the terminal when the person to be protected is the elderly person or the disabled person whose operation or control of the terminal is difficult. 7, in the application of the guardian terminal 100, setting data (e.g., phone book data (name, telephone number, photograph, etc.), periodic positioning period, safe zone setting, Setting data is transmitted to and stored in the server when the control of the mobile phone, the reception of the unregistered number telephone call, the remote power on / off, the home screen screen / name and sound effect, The server may transmit the USSD message to synchronize the application setting data of the protection target terminal 300 with the stored setting data.

The protected terminal 300 stores and operates the synchronized or changed setting data. By using such a function, it is possible to prevent personal information from being weakened by granting authority to only one representative, and to use the terminal for persons who have difficulty in using the terminal.

FIG. 8 shows a procedure for implementing the function of reserving the position alarm in the positioning of the protected terminal 300. FIG. Such a reserved position alarm function can perform positioning at a specific time (for example, a specific day of the week, a specific time (several minutes)) to the protected terminal 300, and notify the position information to the guardian terminal at that time.

First, the guardian terminal 100 can update the reservation server alarm information including the desired time (for example, every Wednesday at 5:00 pm) to the service server 200, and the service server stores such reservation alarm information, You can update existing data if you have one. The stored reservation position alarm information may include a reservation time and the service server 200 may transmit the reservation position alarm information to the protection target terminal 300 so that the reservation target terminal 300 sets the reservation time of the position determination Can be implemented. In one embodiment, the reservation position alarm time is set in the protected terminal 300 that has received the reservation position alarm information, and position positioning can be performed at that time. Here, the protected terminal 300 can perform the real-time location positioning and transmit location information according to the algorithm described in FIG. In another embodiment, the service server 200 stores the reservation time according to the reservation position alarm information, transmits the USSD message to the protection target terminal 300 at the reservation time, activates the position determination, acquires the position information And transmit it. When positioning is performed in the protected terminal 300 at the reservation time, the location information is transmitted to the service server 200. The service server 200 receiving the location information may transmit the location information in various forms The guardian terminal 100 can be notified of the location information of the protection target terminal. With this reservation position alarm function, the guardian can be automatically notified of the position at the reservation time, and it is possible to solve the trouble of requesting the position detection for the protection target every time the position is desired.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents. .
