Description

Method of controlling the number of positioning and a terminal therefor {Method and Terminal for Controlling Positioning Count}

The present invention relates to a positioning number control method and a terminal therefor. More specifically, by reducing the number of periodically repeated positioning in the situation that the terminal does not move, the positioning number control method for reducing the load and battery consumption of the terminal due to unnecessary positioning that does not affect the positioning accuracy and the terminal therefor It is about.

There are two types of positioning methods for providing a current location-related service, a network based positioning method and a mobile terminal based (MS Based) positioning method according to a subject performing the positioning.

In a network-based positioning method, a positioning server receives positioning-related data from a corresponding terminal at a positioning server, performs a position calculation of the corresponding terminal, and provides a location-related service by transmitting the performed position calculation result as a positioning result to the corresponding terminal. to be. On the other hand, the terminal-based positioning method is a positioning method in which the terminal receives positioning-related data once from the positioning server, calculates its position directly without interlocking with the positioning system, and receives a location related service.

The above-described network-based positioning method is suitable for services that require one-time positioning, so it can be used for services such as searching my location and finding friends, and the terminal-based positioning method is suitable for services requiring positioning, so navigation services and tracking ( Tracking) and zone based services.

In the case of navigation services using the terminal-based positioning method, since the positioning target is mostly moving, it is not necessary to adjust the number of positioning periodically, but in the services such as tracking service and zone based service, the positioning target is required. It is necessary to adjust the number of positioning according to the user environment because it may be in a fixed position for a certain time or may have mobility with little change in movement.

However, in the conventional terminal-based positioning method, by performing periodic repetitive positioning without considering whether the terminal to be positioned is moving or at a fixed position, periodically repetitive positioning even in a terminal having a fixed position or a small amount of change in movement. Will be performed. As a result, unnecessary positioning that does not affect the accuracy of the positioning result is repeatedly performed, thereby increasing the load and battery consumption of the terminal.

The present invention for solving the above-described problems, by reducing the number of times of repeated positioning in the situation that the terminal does not move, reducing the load and battery consumption of the terminal by unnecessary positioning that does not affect the positioning accuracy There is a main purpose.

According to an aspect of the present invention for achieving the above object, a method for controlling the number of positioning performed in the terminal, the method comprising: (a) collecting a positioning result by the positioning performed for each positioning execution period; (b) determining whether the terminal moves by using the collected positioning result and a predetermined mobility determination distance value; (c) controlling the positioning frequency by adjusting the positioning performance period according to the determined movement, and after step (c), using the adjusted positioning performance period, steps (a), (b) and steps Provided is a method for controlling the number of positioning, characterized in that the step (c) is repeated.

According to another aspect of the present invention for achieving the above object, a terminal for providing a positioning count control function, comprising: a positioning result collecting unit by positioning performed every positioning execution period; A movement determination unit determining whether the terminal is moved using the collected positioning result and a predetermined mobility determination distance value; And a positioning count control unit controlling the positioning count by adjusting the positioning execution period according to the determined movement.

As described above, according to the present invention, there is an effect of reducing the load and battery consumption of the terminal due to unnecessary positioning, which does not affect the positioning accuracy, by controlling the number of repeated positions periodically according to the movement of the terminal.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function is obvious to those skilled in the art or may obscure the gist of the present invention, the detailed description thereof will be omitted.

1 is a flowchart illustrating a positioning number control method according to the present invention.

As shown in FIG. 1, in the method of controlling the number of positioning performed by the terminal, collecting the positioning result by the positioning performed at each positioning execution period (S100), the positioning result collected in step S100, and the predetermined mobility determination distance. And determining the movement of the terminal using the value (S102) and controlling the number of positioning by adjusting the positioning execution period according to the movement determined in the operation S102 (S104).

After the above-described step S104, steps S100, S102 and S104 are repeatedly performed using the positioning performance cycle adjusted in step S104.

The above-described positioning performed in step S100 is a "mobile station based (MS Based) positioning method" which performs location calculation directly on the terminal without interworking with the positioning system after receiving the positioning related information from the positioning system.

Positioning performed in the above-described step S100 is performed every "location execution period" during a predetermined "location result collection time", and determines whether the terminal moves after the location result collection time. However, the positioning result collection time may be applied by changing the set value in view of the positioning efficiency.

For example, referring to FIG. 3A, when the positioning result collection time is 8 seconds and the positioning execution period is 8/6 seconds, six positioning results are collected during 8 seconds in step S100.

In step S102, it is determined whether the corresponding terminal moves by using the positioning result collected in step S100. Information for such a determination is obtained. The difference value of successive positioning results in the collected positioning results becomes information for determination.

Referring to (b) of FIG. 3, the difference value (2,1) between the second and the first positioning result, the difference between the third and second positioning result (3, 2), the difference between the 4th and 3rd positioning results (4,3), the difference between the 5th and 4th positioning results (5,4) and the difference between the 6th and 5th positioning results. Five difference values including the values (6, 5) are obtained, and the five difference values obtained are information for determining whether to move.

Then, five difference values (difference values (2, 1), difference values (3, 2), difference values (4, 3), difference values (5, 4), difference values (6) (5)) is compared with each of the mobility determination distance values, and a difference value greater than or equal to the mobility determination distance value is extracted. Here, the "difference value" means how much the positioning result for the terminal has changed, and the "mobility determination distance value" is a preset value which is a reference value for determining whether the amount of change in positioning result for the terminal is large or small. It can also be changed and set in light of efficiency.

Thereafter, there are two methods for determining whether the terminal is moved during the positioning result collection time. The first method is to determine how many consecutive difference values of the mobility determination distance value are abnormal. The second method is to determine how many difference values of the mobility determination distance value are abnormal during the positioning result collection time. It is a way of judging whether it occurs. The above two moving determination methods may be distinguished by specific parameters.

First, the first method of determining whether the terminal is moved will be described based on the number of consecutive differences in the mobility determination distance value.

In step S102, the number of cases where the difference value between the nth positioning result and the n-1th positioning result is greater than or equal to the predetermined mobility determination distance value in the positioning results collected for each positioning performance period during the positioning result collection time in step S100 is obtained. If more than a predetermined number of consecutive occurrences occur for a period of time, it is determined that the terminal has moved. However, the terminal is determined to be fixed when the number of cases where the difference between the nth positioning result and the n-1th positioning result is greater than the predetermined mobility determination distance value from the positioning result collected in step S100 occurs below the predetermined number of occurrences. .

Referring to FIG. 3, the first method is described as an example. As shown in FIG. 3A, the positioning result collection time is 8 seconds, the initial positioning execution period is 8/6 seconds, and the number of occurrences is preset to 4. Assume In the six positioning results collected in step S100 for 8 seconds, the difference between the second and the first positioning result (2,1), the difference between the third and second positioning results (3,2) , The difference between the 4th and 3rd positioning results (4,3), the difference between the 5th and 4th positioning results (5,4) and the difference between the 6th and 5th positioning results ( 6,5) are compared with the predetermined mobility determination distance value, respectively, to see how many times the difference value that is greater than or equal to the mobility determination distance value appears continuously, and if the difference value is greater than or equal to the mobility determination distance value, 4 (preset occurrence) Number of times), the terminal is determined to have moved. However, if the difference value is more than four (preset number of occurrences) consecutively more than the mobility determination distance value, it is determined that the terminal is fixed.

Next, a method of determining whether or not a difference value having a mobility determination distance value that is a second method of determining whether the terminal is moved by a predetermined number during the positioning result collection time will be described as follows.

If the number of cases where the difference between the nth positioning result and the n-1th positioning result is greater than or equal to the mobility determination distance value from the positioning result collected in step S100 occurs more than a predetermined number of occurrences, the terminal determines that the terminal has moved, and the predetermined number of occurrences If less than, it is determined that the terminal is fixed.

Referring to FIG. 3, the first method is described by way of example. It is assumed that the positioning result collection time is 8 seconds, the positioning execution period is 8/6 seconds, and the preset number of occurrences is preset to 4. In the six positioning results collected in step S100 for 8 seconds, the difference value (2,1) of the second and first positioning results, the difference value of the third and second positioning results (3,2) , The difference between the 4th and 3rd positioning results (4,3), the difference between the 5th and 4th positioning results (5,4) and the difference between the 6th and 5th positioning results ( 6,5) are compared with the predetermined mobility determination distance value, respectively, and it is confirmed how many times the mobility determination distance value or more appears during the measurement result collection time, and if the difference value is more than the mobility determination distance value, 4 ( If the occurrence occurs more than a predetermined number of times), it is determined that the corresponding terminal has moved. However, if the difference is less than 4 (the predetermined number of occurrences) when the difference value is greater than or equal to the mobility determination distance value, it is determined that the terminal is fixed.

The difference between the two methods will be described through the first and second methods described above.

If the difference value except the difference value of the 3rd positioning result and the 2nd positioning result among the 5 difference values is greater than or equal to the mobility determination distance value, that is, the difference value (2,1), difference value (4,3), difference If the values 5 and 4 and the difference values 6 and 5 are equal to or greater than the mobility determination distance value, the terminal is determined to be fixed by applying the first method, and the terminal is moved by applying the second method. And, the above-mentioned predetermined number of occurrences may change the setting in view of the positioning efficiency.

After performing step S102 of determining whether the corresponding terminal is moved, in step S104 described above, the number of positioning performed during the positioning result collection time is increased or decreased by increasing or decreasing the positioning execution period according to the result of determining whether the terminal is moved.

The reason for adjusting the number of positioning in this way is to reduce unnecessary positioning since the positioning result by periodically repeated positioning is the same every time when the terminal to be positioned is not moving. Of course, in order to reduce the number of positioning it is necessary to determine whether or not the corresponding terminal moves in step S102.

Controlling the number of positioning in step S104 will be described by dividing the number of increasing and increasing the number of positioning.

When the first terminal is determined to be fixed and a control method for reducing the number of positioning is described, if it is determined in step S102 that the corresponding terminal is fixed, in step S104, the positioning execution period used in step S100 is increased by a predetermined time. Reduce the number of positioning performed during the resulting collection time.

Referring to (a) and (b) of FIG. 3, if it is determined that the terminal is fixed in step S102, the positioning result collection time of 8 seconds by increasing the positioning execution period from 8/6 seconds (about 1.33 seconds) to 2 seconds. Reduce the number of positioning performed from 6 to 4. However, it is assumed here that the duration of positioning is increased by 2 seconds.

The control method of increasing the number of positioning by determining that the second terminal has moved has been described. When it is determined that the corresponding terminal has moved in step S102, in step S104, the positioning execution period used in step S100 is reset to an initial value, thereby positioning results. Increase the number of positioning performed during collection time. However, if the positioning performance period used in step S100 is the initial value, the number of positioning is simply maintained.

Referring to (a) and (c) of FIG. 3, if it is determined that the terminal has moved in step S102, the positioning performance period is reduced from 8/6 seconds (about 1.33 seconds) to 1 second, which is the initial value of the positioning performance period. As a result, the number of positioning performed during an 8 second positioning result collection time is increased from six to eight times. However, it is assumed here that the initial value of the positioning performance cycle is 1 second.

In the control method of reducing the number of positioning times as the first terminal is determined to be fixed, when the positioning execution period is increased by a predetermined time, the positioning execution period is increased by using the positioning count reduction control information. The positioning execution period is generated by adding the square of the preset positioning count reduction control information to the positioning performing period used in step S100. Here, the square of the positioning number reduction control information becomes a predetermined time which is further increased.

After controlling the number of positioning by adjusting the positioning execution period in step S104 described above, the process is performed again from step S100.

If it is after the control to reduce the number of positioning by increasing the positioning performance period in step 304, performing the positioning for each of the extended positioning performance period in step S104 during the positioning result collection time, collecting the positioning results, thus obtained positioning results and mobility Determining whether the terminal is moved using the determination distance value, and if it is determined that the terminal is fixed, increasing the extended positioning period by a predetermined time to reduce the number of positioning performed during the positioning result collection time again. And if it is determined that the terminal has moved, resetting the increased positioning execution period to an initial value and increasing the number of positioning performed during the positioning result collection time.

As described above, using the positioning count control method, as shown in FIG. 4, if the terminal is fixed, the positioning execution period is increased by a predetermined time to decrease the number of periodically repeated positioning of the terminal according to the positioning. The load and battery consumption can be reduced, and if the terminal is moving, the positioning performance cycle can be reset to an initial value, thereby increasing the number of repeated cycles, thereby improving positioning accuracy.

2 is a terminal providing a positioning count control function.

As illustrated in FIG. 2, the terminal 200 providing the number of positioning control function collected by the positioning result collecting unit 210 and the positioning result collecting unit 210 for the positioning performed for each positioning performing period during the result collecting time. Positioning result by adjusting the positioning period according to the movement determination unit 220 and the movement determination unit 220 to determine the movement of the terminal using the positioning result and the predetermined mobility determination distance value It includes a positioning count control unit 230 for controlling the number of positioning performed during the collection time.

The above-described movement determination unit 220 is a preset number of cases where the difference value between the n-th positioning result and the n-1 th positioning result in the positioning result collected by the positioning result collection unit 210 is greater than or equal to a predetermined mobility determination distance value. If more than a predetermined number of occurrences occur during the positioning result collection time, it is determined that the terminal has moved, and if less than a predetermined number of occurrences, the corresponding terminal is determined to be fixed.

When the number of times of the control unit 230 determines that the terminal 200 is fixed by the movement determining unit 220, the positioning time period is increased by a predetermined time to reduce the number of times of positioning performed during the positioning result collection time.

The above-described positioning number control unit 230 resets the positioning period to an initial value when it is determined that the terminal 200 has moved by the movement determining unit 220 to increase the number of positioning performed during the positioning result collection time. If the positioning execution period before resetting was the initial value, the positioning count is simply maintained.

As described above, when the terminal performs the location calculation method in the terminal-based positioning method, as shown in FIG. 4, if the terminal 200 is not moving, the positioning execution period is increased by a predetermined time. By reducing the number of periodically repeated positioning, the load and battery consumption of the terminal 200 according to the positioning can be reduced. Of course, when the terminal 200 is moving, the positioning accuracy may be improved by resetting the positioning period to an initial value and increasing the number of times of repeating periodically.
