Description

Location inquiry and reliable service method of mobile communication terminal equipped with PCS {METHOD OF POSITION-REPORT AND RELIEF SERVICE BY MOBILE COMMUNICATION DEVICE INCLUDING GPS}

The present invention provides a location query and a reliable service method using a mobile communication terminal having a Global Positioning System (GPS). When the guardian terminal requests the server for location information of the terminal to be protected, the server performs real-time positioning of the terminal to be protected. The present invention relates to a service method for informing location information of a current protection target terminal to a guardian by obtaining location information by activating and transmitting the acquired location information to a guardian terminal.

Recently, so-called care services have been proposed incorporating IT technology, particularly mobile communication terminal technology, in the social welfare field as well as in traffic accidents, child crime prevention, the elderly and the disabled. For example, in the case of SK Telecom in Korea, by providing a "any care service" using a mobile communication terminal dedicated to the elderly people living alone in the Seosan region, the so-called "U-care service" (Ministry of Health, Welfare and Family Affairs) Is a new welfare service for elderly people aged 65 years or older who use the remote electronic control system to check safety and to rescue quickly when an emergency occurs. .

Currently, as an additional service provided by Applicant's "I-Search Service" (KT (KT)), if you apply for the I-Search service on your child's mobile phone and register the corresponding parent's mobile phone number on the KT server, In the case of notifying parents 'mobile phones every hour, or setting a safe area so that the parents' mobile phones can check their children's entry and exit in the area, the target mobile phone (ie, cell-based location search function using a normal mobile phone) To provide the guardian with the location of their child's mobile phone. In addition, a service for receiving a notification of the location of a child by SMS every setting period by setting a predetermined time period is conventionally provided, and by setting a security zone (a specific area selected by a guardian), for example, within a setting range of about 2 km. In the prior art, a service for allowing a guardian to receive a letter notification when a child enters or exits an area set as a safe zone is provided.

However, since the iSearch service method is based on a mobile phone base station rather than a satellite detection function, the location of the base station is determined as the location of the child by detecting a location depending on the mobile phone base station in the vicinity of the child where the child is located, not a precise location such as navigation. Since the system is notified to the user, there is a problem in that there is a limit in accurately grasping the location information of the person to be protected. In addition, there is a problem that the need for the service is degraded by using the service itself for location data lookup.

In addition, in the elderly or disabled people who have difficulty in operating a mobile communication terminal such as a mobile phone or a smart phone, even if the user possesses the terminal, it is difficult to use the service in the event of an accidental change of settings or in an emergency situation, and thus the Anycare service or In many cases, they did not receive the substantial benefits of reassuring services such as iSearch.

Therefore, the present invention provides a function that allows the guardian to remotely control the function setting of the terminal to be protected for the vulnerable layer (for example, the elderly, disabled, etc.) that is not easy to operate the mobile phone, using an emergency button in an emergency It aims to provide location and security services for children and the elderly by making a video call function so that they can make a phone call with a guardian or contact a security operator affiliated call center.

The present invention provides a location query and security service method using a mobile communication terminal having a GPS, comprising: requesting, by a guardian terminal, server location information of a terminal to be protected; The server receiving the request, activating real-time location by sending a USSD message to the protected terminal with GPS; The terminal receiving the USSD message, performing the positioning operation to obtain location information of the terminal to be protected, and transmitting the obtained location information to the server; Transmitting, by the server, the transmitted location information to a guardian terminal; And displaying the location information received from the server on the guardian's terminal.

In addition, the terminal to be protected includes an emergency button, and when the emergency button is activated, the terminal to be protected is forced to activate real-time location, even if the USSD message is not transmitted, and the terminal to be protected is located in real time. It is possible to provide a location query and peace of mind service method for transmitting the location information with the emergency message to the server, and transmits the emergency message and the current location information received by the server to the guardian terminal. When the emergency button is activated, the terminal to be protected may also implement an emergency situation notification sound to the outside, take a photo of the field, or perform an automatic video call with a guardian.

Furthermore, the guardian terminal and the protected terminal have a dedicated application for implementing the service, and when the setting of the application is changed in the guardian terminal located remotely from the protected terminal, the change information is automatically sent to a server. And a server transmitting the change information to the terminal to be protected, automatically synchronizing application settings of the terminal to be protected, and storing the changed setting according to the synchronization.

The present invention improves the accessibility and necessity of the service by improving the inaccuracy of the location information of the terminal to be protected, based on the GPS, and providing a dedicated application to a general guardian's mobile phone using a mobile communication terminal having a GPS. You can. In addition, when using the USSD method using the WCDMA wireless communication network, the transmission speed is up to 7 times faster than SMS because it is not a storage and transmission method.

Therefore, the present invention provides functions such as providing accurate location information, operating an alarm sound in an emergency, automatic video call with a guardian, and sending a photo of the scene, thereby preventing accidents through quick dispatch, and quickly and accurately grasping the site situation. It has an effect.

Like reference symbols in the various drawings indicate like elements.

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, an Unstructured Supplementary Service Data (USSD) message transmission scheme using Wideband Code Division Multiple Access (WCDMA) scheme is exemplified, but code division multiplexing (CDMA) is used. It is also possible to use Short Message Service (SMS) messages based on Access. 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 data path setting / release method like a data service, not a storage and transmission method. In addition to the USSD, it may be implemented as a multimedia messaging system (MMS) including a picture, a video, and a voice using a 3G mobile communication network.

1 illustrates a service method of the present invention through the operations and procedures between components. The system 1000 according to the present invention includes, for example, a guardian terminal 100, a server 200, and a terminal to be protected 300. The guardian terminal 100 and the protected terminal 300 are, for example, a mobile phone having a GPS module, a 3G mobile communication network access function, a USSD message processing capability, a location based service (LBS) infrastructure access function, a PDA (PDA) personal digital assistants, smart phones, tablet PCs, notebook computers, personal computers, and the like. More specifically, the guardian terminal 100 may be an application running on a smartphone or a computer. In addition, the server 200 refers to a dedicated server according to an embodiment of the present invention having a terminal authentication function, subscriber change information collection function, location history management function and the like.

As shown in FIG. 1, when the guardian terminal 100 wants to know the location of the protected terminal 300, the guardian terminal 100 transmits the location information to the server 200 using an application of the protected terminal 300. You can request The application is a dedicated application program according to an embodiment of the present invention can be used for the computer application, the smartphone application according to the terminal (100, 300) of the present invention. Upon receiving the request, the server 200 requests a USSD message for activating real-time positioning of the GPS to the protection target terminal 300 having the GPS. Here, the USSD is a means for transmitting specific information or commands using a GSM (Global System for Mobile communications) network, and there are two types of MMI (Multi Model Interface) mode and application mode. The string is transmitted to the network or vice versa, and the 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 from GSM. Therefore, WCDMA is compatible with GSM and can use USSD service. In addition, the positioning technology refers to a technology for determining the exact location of the service request terminal using the GPS or the location of the base station of the wireless network.

Upon receiving the USSD message from the server, the terminal to be protected 300 obtains its location information by locating its location, encrypts the location information, and transmits the location information to the server 200. The server 200 receiving the encrypted location information from the protection target terminal 300 transmits the location information back to the protection target terminal 100.

The terminal 100 to be protected may display location information received through the application on a screen of the guardian terminal 100 using content such as a text message, a photo, or a map. Even when the terminal to be protected 300 is a computer, location information can be received using a network (eg, the Internet), and location information can be displayed using an application.

According to the present invention, unlike the cell positioning method using the existing mobile phone base station, the present invention has an effect that it is possible to determine the exact location of the subject of protection without relying on the base station using the GPS equipped with the satellite detection function. have.

2 illustrates a specific real-time location positioning step using the USSD message. As shown in FIG. 2, upon requesting a real-time location inquiry on a guardian terminal or computer network (eg, Web) 100, the service server 200 requests the USSD message transmission to the gateway server 250 and the service. The gateway server 250 interworking with the server 200 may activate the real-time location lookup by transmitting the USSD message to the terminal 300 to be protected. Here, the gateway server 250 has a function of converting a protocol between a plurality of communication networks having different protocols so as to exchange information, and receive encrypted location information from the terminal to be protected. In this description, the illustration of the gateway server 250 is omitted in some cases, and included in the function of the server 200 to explain the operations and procedures between the components. However, it is a matter of course that the gateway server 250 may be physically integrated or separated from the service server 200.

3 is a flowchart illustrating a method of positioning by a protected terminal receiving a USSD message. Before the terminal to be protected receives the USSD message of the location request from the server, the terminal to be protected 300 is in a state of storing a final location result, that is, final location information.

After receiving the USSD message, the location positioning is activated, and first, whether the activity of the terminal is determined by the activity check sensor mounted on the terminal 300 to be protected. The active amount check sensor is a sensor mounted on the protection target terminal 300 to detect a movement of the protection target. When it is determined that there is no movement of the terminal to be protected after the determination, the final location information is transmitted to the server as a location positioning result.

However, when it is determined that there is movement of the terminal, it is determined whether GPS positioning is possible. When GPS positioning is possible, A-GPS (Assisted-Global Positioning System) positioning is performed to transmit the location information obtained through the positioning to the server. Here, A-GPS is a positioning technology in which the chip embedded in the terminal reads the location information sent from the satellite. Even when using GPS satellites, accuracy and usability are poor in urban areas or indoors. In combination with the network method of, the location of the terminal is measured by mixing the location information sent by the terminal and the information generated by the base station.

 On the other hand, when GPS positioning is impossible, the server requests a cell positioning to the server, receives a result of the request, stores the result in the terminal to be protected, and retransmits the result to the server. As mentioned above, when the GPS positioning is difficult as described above, the cell phone base station nearby detects the current location and the current location of the base station is notified to the guardian terminal.

In this manner, the present invention provides fast positioning and accurate location information by transmitting final location information or GPS positioning when there is no movement of the terminal to be protected or when using real-time GPS positioning in comparison with the existing positioning service. Even if the real-time GPS positioning fails, it is possible to perform the cell positioning based on the base station to provide the result quickly.

4 illustrates a method for periodically notifying a location in the service method of the present invention. In the step of requesting the server 200 to the location information of the terminal 300 to be protected, the guardian terminal 100 receives a predetermined time period (eg, time, day of the week, etc.) through an application of the guardian terminal 100. Can be set. By periodically requesting location information according to the set period, the protection target terminal 300 may perform the real-time location positioning according to the algorithm mentioned in FIG. 3 and transmit location information.

For example, according to FIG. 4, the guardian may set a time when the guardian is away from the guardian (eg, when the child is at school and when the parent is at work). You can set the function to be notified.

The guardian terminal 100 automatically receives periodic location notification, and when the protection target terminal 300 does not provide the location notification, the server 200 may automatically notify the location of the terminal through cell positioning. Specifically, as shown in FIG. 4, the server 200 requests the update of the location notification every period set by the guardian terminal, and the server 200 receiving the request transmits a USSD message to the protected terminal 300. In the application of the terminal to be protected, the cycle time is set in the same manner as the period set by the guardian terminal to perform location positioning for each set period and transmit the location information of the protected object.

FIG. 5 illustrates a function for notifying whether or not the security zone has deviated with respect to periodic location information notification. The guardian can set a specific number of areas or buildings (eg, three; home, school, and academy) in the application of the terminal to be protected. When setting the specific area or building, a 'zone' is automatically designated within a radius of 2 km, for example, at a designated location on the map. Thus, the relief zone refers to an 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 an update of the location information of the protection target at a set period as shown in FIG. 4. The server 200 receives the request and transmits the USSD message to the protected terminal 300, and the protected terminal not only sets the same period as the guardian terminal, but also sets the safety zone as the same. Therefore, according to the setting, the protection target terminal 300 performs location positioning for each setting period, and determines whether it is located in the security zone. The terminal to be protected transmits the location information including whether the security zone has left the server 200, and the server transmits the received information to the guardian terminal 100. In case of departure, the location information including the alarm message can be sent. In one embodiment, when the protection target terminal 300 does not leave the security zone, location information may not be notified.

In the case of children or the elderly, since the radius of living does not deviate greatly from the house, most of the terminals to be protected will be located in the security zone, so notification is important when leaving, rather than notification of entering the security zone. In case of departure, the alarm message can be notified to the guardian by text, picture, etc. using vibration, alarm sound, lamp, etc., and in case of departure, the positioning can be performed at a shorter period (eg, 5 minutes or 10 minutes). Could be. In such an implementation, the service further includes a function that allows the server to deliver the protector's setting data to the terminal to be protected, and the terminal to be protected must have a function of determining whether to leave the security zone. Alternatively, the server may receive location information and determine whether to leave the zone of security and deliver the location information to the guardian terminal.

Figure 6 illustrates the action according to the emergency button operation of the terminal to be protected. The protection target terminal 300 may be provided with an emergency button for emergency. The emergency button may be implemented to operate when, for example, long pressing or pressing two or more times in succession. When the emergency button is pressed, the protection target terminal 300 may transmit a notification sound (eg, siren, whistle, etc.) for notifying the outside of an emergency situation so that the other party may run away or notify a surrounding situation of danger. Crime prevention is effective.

In addition, when the emergency button operates, at the same time as the notification sound or after a few seconds, the camera automatically takes a picture using the camera provided with the terminal to be protected, and positioning can be performed to obtain location information. Then, the photographed picture and the location information are transmitted to a server, and the server stores the picture and obtains an accurate address through the picture and the location information, so that a short message is provided to a registered guardian and / or a registered security dispatcher. It may be implemented to transmit in the form of a message. In an embodiment, a short message including an indication that the emergency button is operated together with the photographed picture may be automatically transmitted to the guardian and / or the registered security operator control center. In addition, after the message is sent, a video call function may be automatically activated to be sent to the guardian. This function helps the guardian to recognize and judge the situation quickly and accurately by talking to the guardian.

FIG. 7 illustrates a procedure of controlling a function of the protection target terminal 300 by transmitting application setting data of the protection terminal 100 to the protection target terminal. If the person to be protected is a senior citizen or a disabled person who has difficulty in operating or controlling the terminal, it is necessary to remotely control the operation of the terminal. Therefore, as shown in Figure 7, in the application of the parental terminal 100 (e.g., phonebook data (name, phone number, photo, etc.), periodic location positioning period, the location of the security zone when leaving and leaving, the positioning period, volume Control data, whether or not to allow unregistered number calls, remote power on / off, home screen display / name and sound effects, ringtones, etc., are transferred to the server and stored. Subsequently, the server may transmit the USSD message to synchronize the application setting data of the terminal 300 to be protected with the stored setting data.

The protection target terminal 300 is synchronized, that is, stores and operates changed configuration data. When using such a function, only one representative protector is authorized to prevent the weakening of personal information protection, and the terminal can be used by those who were difficult to use the terminal.

FIG. 8 illustrates a procedure for implementing a function of reserving a location alarm in positioning of the terminal 300 to be protected. The reserved location alarm function may perform location positioning on the protection target terminal 300 at a specific time (for example, a specific day of the week and a specific time (hours and minutes)), and notify the guardian terminal of the location information at the corresponding time.

First, the guardian terminal 100 may update the reserved location alarm information including the desired time (for example, every Wednesday 5 pm) to the service server 200, and the service server stores the reserved location alarm information, If you have existing data, you can update it. The stored reserved location alarm information may include a reserved time, and the service server 200 transmits the reserved location alarm information to the protected terminal 300 to set the reserved time of the location positioning on the protected terminal 300. Can be implemented. As an embodiment, the reserved location alarm time may be set in the protection target terminal 300 that has received the reserved location alarm information, and location positioning may be performed at that time. Here, the terminal to be protected 300 may perform the real-time positioning and transmit the location information according to the algorithm mentioned in FIG. In another embodiment, the service server 200 stores a reservation time according to the reservation location alarm information, and then transmits a USSD message to the protection target terminal 300 at the reservation time to activate location location and obtain location information. Can be implemented. When the location is made to the protection terminal 300 at the time of reservation, the location information is transmitted to the service server 200, the service server 200 receiving the location information in various forms such as, for example, SMS messages, e-mail The guardian terminal 100 may notify the location information of the terminal to be protected. Through the reserved location alarm function, the guardian can be notified of the location automatically at the time of reservation, eliminating the hassle of having to request the location of the protected object every time the location is desired.

Although the invention has been described in detail only with respect to the specific examples described, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
