Description

Method for managing safeguard man of position base}

The present invention relates to a location-based protected object management method that can periodically monitor the voice call and location with the protected object (child, elderly, etc.) using one phone number subscribed to the mobile communication provider.

Personal mobile phones are being developed in various ways such as cellular phones, PCS phones, satellite communication phones. In addition, his technical development is being made continuously, and even more advanced technologies are being developed, and functions and designs are being developed so that the limits of portable communication are unpredictable.

However, all research and commercialization is being made in the development of such advanced technologies, but there are problems in that mobile phones are being used as daily necessities in our daily life, and the additional functions are not easily reflected by the general public.

However, in order to make a voice call between mobile communication terminals, it is necessary to carry a terminal registered with each communication provider. Thus, if a young child, who is a protected subject, needs to carry an expensive device registered with a telecommunication service provider separately from the guardian's terminal, a service fee is charged. In addition, even if the guardian wants to check the location of the protected object in real time, the GPS signal is received and transmitted to the base station only when a call is connected (charged), and the accuracy of location tracking is also very low. lost.

In general, the location tracking methods and problems of the communication terminal are as follows.

First, through the base station identifier and pseudo noise (PN) code value of the mobile communication terminal registered in the Visitor Location Register (VLR) system of the mobile communication network using a cell base location tracking method. It is possible to know in which sector of which base station the mobile communication terminal is located. However, considering that one sector of one base station serves a large area in a mobile communication network, it is not suitable for a service requiring precise location tracking.

On the other hand, the base station ID (BID: Base station IDentifier) of the neighboring base station that the mobile communication terminal has moved by each of the adjacent neighbor base station and the PN chip delay time (TOD: Time Of Delay) The distance between the communication terminal and each neighboring base station is calculated, and the approximate latitude and longitude region of the current position of the mobile terminal is obtained by applying a mobile terminal location area calculation algorithm to the calculated distance and the latitude and longitude coordinate information of the neighboring base stations. Can be. However, the location area tracking of the mobile communication terminal by this method alone is not suitable for a service requiring precise location tracking.

When the mobile communication terminal responds to a disaster relief service or the like, it is difficult to accurately determine the location of the terminal holder in the related art, and thus the location is determined by the cell radius of the mobile phone base station. As a result, even if an emergency rescue request is made, problems such as time lag may occur, and there is a problem in that it is impossible to efficiently respond to an emergency disaster because it is impossible to provide a service in connection with GIS information that can cover the whole country. Due to these limitations, it was not possible to provide a highly accurate service for emergency rescue requests that terminal subscribers needed promptly. In addition, since most of the protected objects of the disaster relief target do not know exactly where they belong, there is a problem of delay in rescue because they cannot accurately express the location even when the emergency rescue request is made.

The present invention, which is proposed to solve the above problems, by using the number of the mobile communication terminal subscribed by the guardian, the voice call and the position periodically with the protected object through a low-cost portable terminal device capable of GPS reception An object of the present invention is to provide a location-based method for managing a protected object for monitoring and providing a quick and accurate emergency rescue service to a protected object since the exact location of the protected object in emergency disaster can be determined.

In order to achieve the above object, the present invention provides a method for managing a location-based protected object, comprising: a first step of managing a database with a same phone number by pairing a guardian terminal and a protected object terminal; A second step of analyzing a called number when calling from the guardian terminal; And a third step of connecting the protected object terminal to connect a call between the protector and the protected object when the calling number (the number of the guardian terminal) and the called number are the same according to the analysis result of the second step. It is characterized by.

In addition, the present invention is a fourth step in which the protected object terminal periodically reports its location; And a fifth step of transmitting the current location of the protected object terminal to the guardian terminal according to the request of the guardian terminal.

The present invention may also include a sixth step of identifying a current position of the protected object terminal according to a rescue request of the protected object terminal; And determining a rescue center closest to the current location of the protected object terminal to make a rescue request to the corresponding rescue center.

The present invention may further comprise an eighth step after the first step is performed, when the call is originated from the protected object terminal, connecting a corresponding guardian terminal to connect a call between the protected object and the guardian.

The present invention implements a low cost mobile terminal device capable of only GPS reception, voice signal and short message service (SMS) by sharing a telephone number subscribed by a guardian to a telecommunications carrier, and the base station when the guardian dials his / her own number. By connecting with the terminal device carried by the protected object, a voice call is possible between the protector and the protected object, and the location of the protected object may be monitored in real time. That is, the device carried by the protected subject periodically receives a GPS signal and transmits it to the terminal of the guardian, whereby the guardian can monitor the position of the child at any time. In addition, the terminal device carried by the protected object supports voice calls and emergency rescue services with the guardian.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a configuration of a hardware system for location-based protected object management to which the present invention is applied, and includes a radiotelephone-based communication network and a GPS satellite network (or broadcast network) for location detection, a control system for emergency rescue, and an emergency rescue system. By linking the centers (hospitals, fire departments, police stations, etc.), the guardian is shown an example of an environment that can effectively support advanced location services and emergency rescue services using wireless data services and telephone services.

The user (guardian) of the mobile communication terminal 20 registered in the mobile communication provider applies for the use of the portable terminal device 10 to manage a protected object (child, senior citizen, etc.) to make a phone call to his / her number. A voice call can be made with (10). That is, the network control station (central center 30) of the mobile communication operator makes a call with the portable terminal device 10 when the mobile communication terminal 20 applying for use of the portable terminal device 10 attempts its own number. Determine if you want, find it and connect. You can also send text messages in the same way.

The portable terminal device 10 does not need to be additionally assigned a number, and only the reception is possible by sharing the phone number with the ESN of the mobile communication terminal 20 registered in the mobile communication service provider. However, if necessary, as shown in FIG. 2, an emergency rescue center 40 such as 119 or a call with a guardian (a call with the mobile communication terminal 20 applying for the use of the portable terminal device 10) may be available. . In addition, the portable terminal device 10 should be capable of GPS reception. Thus, when the GPS signal is periodically received and transmitted to the central center 30 through the wireless communication network, the central center 30 interprets the position of the portable terminal device 10 so that the mobile communication terminal 20 may be a portable terminal device. Tell us immediately when you want the location of (10).

The portable terminal device 10 provided by a protected object (child, senior citizen, etc.) shares a telephone number of a guardian (parent, etc.) with a communication service provider, but can only be received by the guardian's mobile terminal 20. Calls to other numbers are not possible and can only be sent to the guardian's mobile terminal 20.

As shown in FIG. 2, the portable terminal 10 includes a call button (call button) for voice call with a guardian, an emergency rescue button (emergency button), an LCD, an ear jack, and the like. And periodically receive the GPS signal through the GPS satellite network (or broadcasting network) to determine the current exact location in real time and send it to the central center 30 through the wireless communication network, and direct call with the guardian through the call button It is possible, without a direct call with the counselor residing in the center center 30 can be requested by SMS automatically with a simple operation (emergency rescue button) only.

That is, the portable terminal device 10 provided by the protected object receives a GPS signal through a GPS satellite network (or a broadcasting network), grasps the current accurate location in real time, and transmits the same to the central center 30 through a wireless communication network. When the protected object presses the call button for the guardian's call, the protector connects the call with the guardian's mobile communication terminal 20. In addition, when the protected object notifies that an emergency has occurred through a button operation (that is, pressing an emergency rescue button), the portable terminal 10 recognizes that an emergency has occurred and identifies the type of emergency and processes it into an SMS form. To the central center 30 through a wireless communication network. At this time, when generating an emergency rescue SMS message, a predefined code (for example, TI code of the SMS message, etc.) is automatically generated. Of course, when an emergency occurs, the protected object may be confirmed by pressing the emergency rescue button, it is obvious that voice recognition technology may be confirmed by voice (for example, "emergency", "emergency situation", etc.). In addition, a one-on-one call with a counselor residing in the central center 30 is also possible by pressing the emergency rescue button.

Here, the portable terminal device 10 corrects the position data received from the GPS satellite network (or the broadcasting network) by using the D-GPS, generates accurate position information, and transmits it to the central center 30 in real time. That is, the GPS correction value is set based on the coordinate set as the absolute measurement value, and the error of the position data is compared and corrected to generate accurate position information and transmitted to the central center 30 in real time through the wireless communication network. Therefore, whenever the guardian's mobile communication terminal 20 requests the position confirmation of the protected object, the central center 30 can grasp the current position of the protected object and notify the guardian's mobile communication terminal 20.

The wireless communication network includes a communication means composed of a base station, a control station, an exchange station, a short message service center, a short message service server, and the like for transmitting and receiving data using SMS, and code division multiplexing the emergency rescue message from the portable terminal device 10. It transmits / receives with the central center 30 through SMS through a Code Division Multiple Access (CDMA) network.

Here, the short service center connects each portable terminal device 10 to the central center 30 through the short service server using SMS. Accordingly, the portable terminal device 10 generates an emergency rescue SMS field based on the SMS message to be transmitted, and the central center 30 analyzes the SMS message to recognize that the location and emergency situation of the protected object have occurred and identify the type of emergency. Figure out.

That is, the central center 30 receives the SMS message transmitted through the wireless communication network, and analyzes it in the SMS processing unit 31 under the control of the control unit 32 to identify the emergency situation and the type of emergency, The GIS 33 is searched using a message (D-GPS information included in the message) to determine the exact location of the protected object by linking a road name, an administrative district name, a distance, and the like on a map. That is, the exact location of the protected object is determined by mapping subscriber information on a map and predefined emergency rescue center information.

In addition, the center center 30 detects the emergency rescue center 40 nearest to the area where the protected object is located based on a predefined DB and connects an outbound call to the identified emergency rescue center 40. A rescue request is made and the guardian's mobile communication terminal 20 is connected to notify that the protected object is in an emergency situation. Of course, the central center 30 may notify the emergency matter (emergency type), the location of the protected object, etc. to the emergency rescue center 30 by using an ARS or a resident counselor using a voice call.

After the rescue request to the emergency rescue center 40, the central center 30 connects the call to the guardian to inform the completion of the emergency rescue request. At this time, a predefined SMS message is transmitted through the wireless communication network so that the guardian's mobile communication terminal 10 can be displayed or heard in voice. Then, the guardian's mobile communication terminal 20 receives the SMS message, interprets it, and automatically outputs it to the speaker or the display device. Of course, without using the SMS, the central center 30 may notify the guardian's mobile communication terminal 20 directly through the voice call completion of the emergency rescue.

Here, the emergency rescue center 40 means a public interest group (for example, a hospital, a fire station, a police station, etc.) such as a rescue request or a response to a crime report.

On the other hand, the GIS 33 allows the database to receive the results in a variety of map forms according to the needs of the user. In the GIS 33, geographic information is represented by geographic coordinates such as latitude and longitude, or by actual information such as an address, a postal code, and a house number. The GIS 33 converts this geographic information into a location on a map and displays it.

3A and 3B are flowcharts of an embodiment of a method for managing a location-based protected object according to the present invention.

As shown in FIG. 3A, a user (guardian) of a mobile communication terminal 20 registered in a mobile communication provider applies for the use of the portable terminal device 10 for a management object (child, elderly person, etc.) management service (304). When the user calls his / her number (301, 302), the mobile terminal 10 can make a voice call (306). That is, the network control station (central center 30) of the mobile communication provider when the call originating from the mobile communication terminal 20 (301), check the called number (302), if the called number is not the same as the calling number is general In step 303, the call processing procedure is regarded as the call origination, and if the called number is the same as the calling number, it is checked whether the mobile terminal 10 is applied for use (304).

As a result of the test, when the called number is the same as the calling number but the user does not apply for the use of the portable terminal device 10, an error message is sent and the called number is the same as the calling number and the user applies for the use of the portable terminal device 10. In the case of a call with the mobile terminal 10, the mobile terminal 10 is connected to the call with the portable terminal 10 (306).

On the other hand, the portable terminal device 10 does not need to be additionally assigned a number, and can receive only by sharing the phone number with the ESN of the mobile communication terminal 20 registered in the mobile communication provider. However, if necessary, a call with the emergency rescue center 40 or the guardian (a call with the mobile communication terminal 20 applying for the use of the portable terminal device 10) is possible. In addition, since the portable terminal device 10 is capable of GPS reception, the portable terminal device 10 periodically receives the GPS signal and transmits the GPS signal to the central center 30 through the wireless communication network.

Accordingly, as shown in FIG. 3B, when the network control station (central center 30) of the mobile communication operator receives a call 311 from the mobile terminal 10, the received call type is analyzed (312), and the GPS is analyzed. When the signal is received, the current accurate position of the portable terminal device 10 is identified and stored in real time (313) and stored (314), every time the position request of the protected object from the guardian's mobile communication terminal 20 is requested (315), The current location of the protected object is determined and notified to the guardian's mobile communication terminal 20 (316).

In addition, when a call button signal is detected, a call is sent to the mobile communication terminal 20 of the guardian mapped to the portable terminal 10 of the protected object to connect a direct call with the protected object and the guardian (317).

In addition, when the protected object notifies that the emergency has occurred through a button operation (that is, pressing an emergency rescue button), the portable terminal 10 recognizes that an emergency has occurred and identifies the type of emergency and processes it into an SMS form. Transmits to the central center 30 through a wireless communication network, and the central center 30 interprets the SMS message transmitted from the portable terminal apparatus 10 through the SMS processing unit 31 to recognize the emergency situation and the type of emergency. After checking the GIS 33 using the interpreted message (D-GPS information included in the message), the exact location of the protected object is identified by linking road names, administrative names, and distances on the map (318). By storing the current location of the terminal device 10 (319), by identifying the nearest emergency rescue center 40 in the area where the protected object is located by connecting a call (Outbound call) to the identified emergency rescue center 40 rescue A request is made (320) and the guardian's mobile communication terminal (20) is connected to notify that the protected object is in an emergency (321). At this time, the central center 30 uses an ARS or a resident counselor as an emergency rescue center (eg, a hospital, a fire station, a police station, etc.) 30 using voice calls to protect an emergency matter (emergency type). The location of the object may be informed.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible in the art without departing from the technical spirit of the present invention. It will be clear to those of ordinary knowledge.
