Next, various functions provided by the portable terminal device of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 2, the portable terminal device 100 provides a location notification function, a location tracking function, a general GPS terminal function, an information display function, a communication device connection function, a GPS status data receiving function, and the like. The notification function and the location tracking function will be described with reference to FIGS. 3 and 4.

3 is a flowchart illustrating a process of transmitting location information to a control server through a portable terminal device according to an exemplary embodiment of the present invention.

First, since the terminal device 100 of the present invention has a built-in cellular phone function, it is possible to make a call with the other party through the CDMA communication network of the CDMA communication module unit 120 at normal times. The call mode is operated by the same method as using a normal mobile phone by operating a call key or the like.

In the state of carrying such a terminal device (ST100), if the terminal device user is distressed or has an accident, the user must accurately notify the third party of his location and receive the rescue (ST102).

This is possible because the GPS module unit 102 continuously receives radio waves from the GPS satellite 1 and calculates position information of the terminal device, so that the position information is transmitted to the central processing unit 101. Here, the GPS module unit 102 receives satellite data propagation from one or more satellites through a satellite antenna and calculates coordinates for the current position, using an optimal number of satellites in order to minimize errors in the position information (ST104). ).

As described above, when the central processing unit 101 receives the location information from the GPS module unit 102 and transmits the location information to the CDMA communication module unit 120, the CDMA communication module unit 120 supports the location information. The transmission is transmitted to the control server 140 through the CDMA communication network (ST106).

The control server 140, upon receiving the location information, grasps the current location of the terminal device 100 according to its own control process and displays the location information on a display unit (not shown), or displays the location information in another mobile communication. It is to be delivered to a terminal or a computer terminal (for example, 119 rescue team, police, etc.) so that the risk can be coped quickly (ST108).

Here, since there is no way for the user of the terminal device 100 to know whether an emergency situation such as distress or accident has occurred, the control unit according to the present invention has a position for changing to a mode for notifying location information in a general call mode. Preferably, an information notification key is provided.

Location information by this process has the advantage that can be more accurate than the location information tracking service through the conventional mobile phone.

On the other hand, when a terminal device user stores his route to use location tracking, or when the terminal device user is a child or difficult to operate directly due to a disability, the terminal device user can check the current location of the user through the location tracking method.

This will be described with reference to FIG. 4, which is a flowchart showing a location tracking process according to the present invention.

First, the terminal device of the present invention is a service capable of checking a user's movement path by storing his path (ST110).

This is when the user needs to check his or her location when moving to a certain point in the state of carrying the terminal device 100 (YES in ST112), when the user operates the location information confirmation key, the central processing unit 101 ) Displays the current position information grasped by the GPS module unit 102 on the output display unit 106 (ST114). In this case, the location information is stored in the memory 108 at a predetermined time according to a state in which the location information confirmation key is operated, or when the key is operated, or according to a programmed control process of the central processing unit 101. In operation ST116, the user can confirm the path of the user's movement through the location information confirmation key operation.

In addition, when a location confirmation request is generated from an individual or an institution that wants to know the location of a user who has a terminal device 100 and a contact for a certain period of time from contact with a child or a disabled person who has difficulty in operating the terminal (ST118), The server 140 requests an attempt to establish a call with the terminal device 100 through the CDMA communication module unit 120, and the central processing unit 101 communicates with the control server 140 according to the call call setting signal request. Control to activate the path (ST120).

Thereafter, the central processing unit 101 receives the current location information of the terminal device 100 from the GPS module unit 102 and transmits the location information to the control server 140 through the set path (ST122). .

Then, the control server 140 may check the current position of the terminal device 100 (ST124). This makes it possible to easily cope with accidents, distress and lost children.

On the other hand, the terminal device 100 of the present invention is the initial on (on) driving or when the GPS module unit 102 receives poor reception sensitivity from the GPS satellite 1, the GPS module unit 102 is the GPS satellite (1) Since it takes a minimum of several minutes to several ten minutes to calculate the location information by receiving radio waves from the control panel, the control server 140 may not be able to receive the current location information of the corresponding terminal device 100 smoothly. .

Accordingly, the reception signal detecting unit 104 of the terminal device 100 continuously detects the signal provided from the GPS satellite 1, and if the satellite signal provided from the GPS satellite 1 is weak, the terminal device 100 If the GPS reception sensitivity level that can be normally operated is less than or equal to the reference level value, the central processing unit 101 receives the detection signal from the reception signal detection unit 104 and the GPS module unit 102 can operate faster. A process of reducing the effective data acquisition time of the GPS module unit 102 is performed.

The process is that when the satellite earth station 2 provides the real-time satellite situation data to the satellite situation data server 3, the satellite situation data server 3 stores the satellite state data, and the central processing unit 101 The GPS module unit 102 is controlled to connect to the satellite data server 3 through the communication device 130 and to download the satellite data from the satellite data server 3.

In accordance with the download of the satellite situation data, the GPS module unit 102 is in a state in which a normal operation capable of quickly receiving information about the GPS satellite 1 is possible, and the central processing unit 101 controls the location information. Send to 140 to ensure that the location is always available.

On the other hand, the terminal device 100 can be used by receiving power from the built-in battery, but in this case, if the user keeps on (on) in order to prevent the use time due to battery consumption is reduced by the user's sleep key When this is manipulated, the current mode is switched to the standby mode, thereby reducing the power consumption.

Of course, in the standby mode, the GPS module unit 102 receives the signal from the GPS satellite at a predetermined time or randomly so that the location information is provided, even if the location tracking service is provided, the control server 140 easily checks the location. Can be.

In addition, the terminal device 100 may be connected to a wireless communication device such as a mobile phone (CDMA, GSM, TRS, etc.), wireless Internet (Wibro, Wimax, WiFi) and wired communication device to the communication device connection unit 122, In this case, various types of news and life information provided from the wireless communication device and the wired communication device may be displayed on the output display unit 106.

Here, in the state where the wired / wireless communication device is connected to the communication device connection unit 122, if the charge battery provided in the terminal device 100 of the present invention is discharged and cannot be used, the central processing unit 101 The controller controls the power of the wired / wireless communication device connected to the communication device connection unit 122 automatically according to the remaining charge of the rechargeable battery.

In addition, the communication device connection unit 122 provides a protocol automatic conversion function so that signal transmission and reception are performed by applying the same communication method according to the type of wired or wireless communication device (CDMA, GSM, TRS, Wibro, Wimax, WiFi, etc.) to be connected. As a result, a separate protocol conversion work is not required, and convenience of use can be expected.

As described above, according to the portable terminal device and the method of using the GPS and the communication function of the present invention, using the terminal device to notify the location of the desired location, or the control server to accurately check the current location of the terminal device Because of this, even in an emergency situation such as accidents, distress, lost children, there is an effect that can be replaced quickly and easily.

In addition, in the present invention, even if the reception sensitivity is not smoothly provided from the GPS satellites, since the GPS module unit receives the satellite situation data from the satellite situation data server, the effective data acquisition time required for driving the GPS module unit is shortened, thereby providing location information. It is easy to search.

In addition, since the terminal device of the present invention is portable due to its own power supply and has various functions such as the above-described positioning function, GPS terminal function, news information display function, and various communication network connection functions, product competitiveness is superior to similar products. It can dominate.
