The present invention relates to a mobile communication terminal system having a precise positioning function and a control method thereof. In particular, a three-axis acceleration sensor is mounted on a terminal, and when a building is entered, drawing information about a corresponding building is generated to generate a path designated by a user. The present invention relates to a mobile communication terminal system equipped with a precise positioning function for tracking a target position and a control method thereof.

In general, a mobile communication terminal system refers to a system capable of transmitting or receiving voice or data mainly by using a mobile communication base station to a person having a transmission / reception facility installed in a mobile by a wireless communication method. The number of concurrent users in the region was variable, not fixed, and it was difficult to accurately predict the propagation path of radio waves due to reflection by features. However, when the mobile communication terminal uses a satellite positioning system (GPS) and a mobile communication network system located above the earth, positioning of the mobile communication terminal can be more easily processed.

Then, referring to the mobile communication system associated with the conventional mobile communication terminal as described above with reference to FIG. 1, receiving its position coordinates from the GPS 70 and using it as its location information and relaying the radio call of the mobile device. Location information of the base station system unit 72 composed of a plurality of base stations 71A-N and the base station system unit 72, for example, the corresponding base stations 71A-N received from three or more base stations 71A-N. It includes a mobile communication terminal 73 to calculate its location information by using and to receive and receive the radio call.

On the other hand, looking at the location tracking method of the conventional mobile communication terminal as described above, first, when the mobile communication terminal 73 is turned on, the mobile communication terminal 73 from the base station (71A-N) that manages the cell of the location The positional coordinates of the base stations 71A-N and the data signal for call processing are always received so that they are in the idle state so that the call reception can be performed at any time. At this time, if the user of the mobile communication terminal 73 wants to check his or her location, and sets the positioning menu provided in the terminal 73, the corresponding location request signal of the base station system unit 72 The location server 74 is transmitted to the location server 74 and accordingly the location server 74 uses location information input from the terminal 73 and location information of a plurality of base stations 71A-N that manage the corresponding terminal. The location of the terminal 73 is calculated and then transmitted to the corresponding terminal 73. Then, the mobile communication terminal 73 displays the positioning information transmitted from the positioning server 74 on the display 75 of the terminal 73.

However, since the conventional method for determining a location of a mobile communication terminal is a method using a network using GPS, that is, location coordinates of three or more base stations, not the location information of the terminal itself, the distance or place between the base station and the base station or between the base station and the terminal. Because the error range is quite wide, it is impossible to precisely track the location of the terminal. Moreover, when the terminal moves in a specific building located in one base station cell, the location of the terminal cannot be measured in detail and it is very inconvenient to use. There was a problem.

Therefore, the present invention has been invented to solve the above problems, and since the terminal can accurately track the target position through the 3-axis sensor in a building or a large building where the location of the GPS cannot be tracked. It is an object of the present invention to provide a mobile communication terminal system having a precise positioning function and a control method thereof that can significantly improve the accuracy of terminal location tracking.

Another object of the present invention is to easily grasp the desired location information in a large building to move quickly to the corresponding location, according to the mobile communication terminal system equipped with a precise positioning function that can also maximize the user convenience of the terminal accordingly To provide a control method.

The present invention for achieving the above object is a mobile communication terminal for processing a radio call signal, is installed on one side of the mobile communication terminal and display the display data, etc. according to the location tracking of a specific building variable display according to the movement of the terminal A display unit for displaying data, a wireless module unit for receiving internal drawing information of a building transmitted from the wireless information transmitting / receiving unit of the specific building, and the movement of the terminal when the terminal enters into the specific building The three-axis acceleration sensor unit for measuring in detail, the display data of the specific building received as the terminal enters through the wireless module unit and the three-axis movement data of the terminal detected by the three-axis acceleration sensor unit is analyzed and processed A main control unit for displaying a variable position on a display unit, and from a specific building according to a storage control signal of the main control unit. Provides Shinhan display data and having a precise positioning capabilities including a memory for storing a variable-position information of the terminal within a particular building a mobile communication terminal system.

Another feature of the present invention is the building information receiving processing step of receiving and analyzing the drawing information inside the building from the wireless information transmitting and receiving unit of the building when the current precise location tracking function is set in the mobile communication terminal, and the building information receiving processing A terminal position calculating step of sensing the position of the terminal moved in the building through the three-axis acceleration sensor after the three-axis after the step and calculating the position, and the current position of the terminal calculated after the terminal position calculating step Provided is a control method of a mobile communication terminal system having a precise positioning function comprising a terminal position display step of displaying on a drawing implemented on a screen of a display unit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the present invention is installed on a part of the body of the mobile communication terminal 1 to display various information signals therein, and to display data according to the position tracking of a specific building 2, for example, a graphic process. Receives a display unit 3 for displaying the interior view of the building as variable display data according to the movement of the terminal 1 and internal drawing information of the building transmitted from the wireless information transmitting and receiving unit 4 of the specific building 2. And a wireless module unit 5 for processing radio call signals transmitted and received within the mobile communication terminal 1, and when the mobile communication terminal 1 enters a specific building 2, A three-axis acceleration sensor unit 6 measuring movement in three axes, for example, flat walking, ascending and descending, and a specific building 2 received as the terminal 1 enters through the wireless module unit 5. 3 of the terminal detected by the display data of the Main control unit 7 for analyzing the axis movement data to display the variable position of the terminal 1 on the display unit 3 and to control the overall function of the mobile communication terminal 1, and the main control unit 7 A codec unit 9 for converting an analog voice signal inputted through the handset 8 into a digital signal or converting a digital voice signal into an analog signal according to a call connection control signal of the control unit; Memory unit for storing the display data received from the specific building (2) and the variable position information of the terminal 1 and the various information of the mobile communication terminal (1) in accordance with the storage control signal of 10).

One end of the main control unit 7 is connected to a key panel unit 11 for inputting a user function setting signal to the main control unit 7.

Next, a control method applied to the above apparatus will be described.

The method of the present invention proceeds from the initial state S1 to the function setting checking step S2 as shown in FIG. 3 and checks whether the current precise position tracking function is set in the mobile communication terminal. At this time, if the current position tracking function is not set in the mobile communication terminal as a result of checking the function setting step (S2), the process proceeds to the general call processing function execution step (S3) to execute the general call processing set in the mobile communication terminal. Let's do it.

That is, when power is applied to the mobile communication terminal 1 of the present invention, the main control unit 3 of the mobile communication terminal 1 proceeds to an initializing state to form necessary information from the internal memory unit 10 to perform an initialization process. Run it and proceed to standby.

At this time, the main control unit 3 of the terminal 1 recognizes when the user inputs a phone number through the key panel unit 11 and presses a call button, and the user inputs the phone number to the memory unit 10. In addition to the storage, the system accesses the base station system unit 12 using the access channel through the wireless module unit 5, and then transmits an outgoing signal to the corresponding telephone number. Then, the base station system unit 12 processes the outgoing signal sent from the terminal 1 and transmits an incoming signal to the counterpart terminal 13 to form a call. Then, when the user of the terminal 1 inputs a voice signal through the handset phone 8, the codec unit 9 of the terminal 1 signals the voice signal input through the handset phone 8. Process and input to the wireless module unit (5). In addition, the wireless module unit 5 under the function control of the main control unit 7 of the terminal 1 wirelessly processes the voice signal input through the codec unit 9 and passes through the base station system unit 12. Since the transmission to the terminal 13 makes a normal call.

On the other hand, if the current position tracking function is set in the mobile communication terminal as a result of checking during the function setting confirmation step (S2) proceeds to the building information receiving processing step (S4) when the building enters the building from the wireless information transmitting and receiving unit of the building inside the drawing Receive and analyze the information. Then, after the building information receiving processing step (S4) proceeds to the path generation step (S5) to generate a path according to the tracking target position set by the user of the terminal and drives the three-axis acceleration sensor. In addition, after the path generation step (S5) proceeds to the terminal position calculation step (S6) to calculate the position of the terminal to be moved to the three axes in the building through the three-axis acceleration sensor to calculate the position. On the other hand, after the terminal position calculating step (S6) to proceed to the terminal position display step (S7) to display the current position in the building of the terminal calculated on the screen implemented on the screen of the display unit.

    In other words, when the user of the terminal 1 of the present invention goes to any specific position in the specific building 2, the user may set the corresponding menu through the key panel unit 11. At this time, the main control unit 7 of the terminal 1 executes a precise position tracking function and when the terminal 1 is moved, when the specific building 2 enters, the radio information transmitting and receiving unit 4 of the corresponding building 2 is moved. Drawing information inside the building is received and analyzed through the wireless module unit 5 and then stored in the memory unit 10. Then, the main control unit 7 automatically generates a path according to the target position in the building set by the user and guides the target position on the building drawing implemented on the display unit 3. At this time, the main control unit 7 drives the three-axis acceleration sensor unit 6 to track the position of the terminal in three axes, for example, flat walking, ascending and descending details as shown in FIG. After recognizing the location of the terminal, the location of the terminal is calculated based on this. The main control unit 7 then displays the calculated current position of the terminal on the drawing implemented in the display unit 3.

Here, the main controller 7 obtains the current state displacement C (k) as shown in Equation 1,

C (k) = {Cx (k), Cy (k), Cz (k)}

In addition, the displacement vector calculation when the movement motion is detected can be obtained as shown in Equation 2.

Cx (k + 1) = Cx (k) + Slcos (2πAh),

Cy (k + 1) = Cy (k) + Slsin (2πAh),

 Cz (k + 1) = Cz (k) + Ss

Where Sl is the unit stride, Ss is the height of one stairway, Ah is the user's direction of travel (angle), and x, y, and x is the xyz coordinate system subscript.

As described above, the present invention is equipped with a three-axis acceleration sensor in the terminal and receives the drawing information for the building upon entering the building by creating a path designated by the user to move the target location to track, building or GPS location tracking is impossible Since the terminal can precisely track the target position through the 3-axis sensor in a large building, it has an advantage of significantly improving the accuracy of the terminal position tracking.

Another object of the present invention is to easily grasp the desired location information in a large building to move quickly to the corresponding location, thereby also maximizing the user convenience of the terminal.
