Description
The present invention relates to a method for shortening a positioning time in a security terminal, and more particularly, it relates to a method for shortening a positioning time in a security terminal by applying a condition for predicting the GPS positioning possibility, performing GPS positioning when it is determined that GPS positioning is possible within a given GPS positioning time- And to a method for shortening the positioning time by immediately stopping the GPS positioning and performing network-based positioning when it is judged impossible.
The security terminal includes a location tracking and location monitoring service in which a person to be protected (elderly person, preschool child, and lower grade elementary school children) carries a terminal and easily grasps location information by a carer, It is a dedicated terminal that provides an emergency notification service to notify the guardian of the emergency situation.
Therefore, in the position monitoring service for the safety terminal for the conventional technology, when a guardian executes a position monitoring function by setting a position monitoring area (e.g., position coordinates and radius) in a PC or a mobile terminal, ) To calculate the distance between the established surveillance coordinates and the acquired current location to check whether the surveillance area has entered or departed from the surveillance area and whether the surveillance subscriber has entered or exited the predetermined surveillance area To the server of the mobile communication company, and the mobile communication server informs the mobile communication terminal of the guardian through the text / voice message or informs the guardian through the voice message through the ordinary telephone.
As shown in FIG. 1, the method for acquiring location information of the security terminal according to the related art sets a GPS timeout period T, and when the location monitoring service requests location information, the GPS device of the security terminal is activated If the GPS positioning (with an error range of significantly less than 20-30 meters) starts and the GPS positioning is successful within a given timeout period (T), the GPS positioning result is used to provide position information, If the GPS positioning fails within the time T, the network-based positioning (e.g., positioning by neighboring base stations) (error range is in the order of tens to hundreds of meters) And a method of providing location information is used.
Therefore, when receiving the GPS positioning request, the security terminal waits until the GPS timeout time (T) and acquires the available visible satellites to calculate the position of the terminal by receiving GPS signals from four or more satellites. If the number of visible satellites is less than 4 or the signal intensity of some satellites is too weak even if the number of visible satellites is 4 or more as a result of searching for available visible satellites during the period T, .
Therefore, in the area where the security terminal normally receives the GPS signal, the GPS positioning is performed by receiving the GPS signal from the GPS satellite within the timeout period (T).
However, in an area where the GPS signal is not received or it is difficult to receive the signal, since the GPS positioning fails during the timeout period (T) and the network-based positioning information is received from the communication network, (After the elapse of the time-out time T), the network-based location location information is obtained. Therefore, there is a problem that a time which does not need to wait is awaited.
In addition, if the GPS device is a device consuming a lot of power and continuously attempts GPS positioning during the timeout period (T) even in an area where the GPS signal is not received or the signal is difficult to receive (the area where the GPS positioning fails) This unnecessary attempt of GPS positioning increases the power consumption and increases battery consumption of the security terminal.
SUMMARY OF THE INVENTION In view of these problems of the prior art, the present invention provides a method for shortening a positioning time in a security terminal.
According to an aspect of the present invention, there is provided a method for shortening a positioning time in a security terminal,
Setting a prediction condition for predicting whether a GPS positioning is possible, a timeout time (T1) until a prediction condition is confirmed, and a timeout time (T2) for a GPS positioning operation; When the safe terminal receives the positioning request, it starts the GPS positioning and determines whether it meets the prediction condition within the timeout time T1; Performing GPS positioning until a timeout period (T2) when it is determined that the GPS positioning is possible if the determination is made; And a step of stopping the GPS positioning and performing a network-based positioning when the determination result is not satisfied or the timeout time (T1) has elapsed, wherein the timeout time (T1) Out time (T2).
In the case where the GPS receiver can not perform the GPS positioning as a result of the determination based on the prediction condition, the GPS positioning is immediately stopped, the network-based positioning is performed, and the network- In addition, it is possible to shorten the time for providing location information, and it is possible to reduce the power consumption due to the GPS positioning attempt for a certain period of time despite the inability to perform the GPS positioning. It is possible to prevent delay in providing location information according to the location information.

Figure 2 shows the overall configuration of the present invention.
FIG. 3 shows a flowchart of a method for providing location information according to the present invention.
Now, the overall configuration of the security terminal according to the present invention will be described in detail with reference to FIG.
As shown in FIG. 2, the safety terminal of the present invention includes a condition (prediction condition) for predicting whether a GPS positioning is possible, a timeout time (T1) until a prediction condition is confirmed and a timeout time (2) for determining whether the GPS positioning is successful within the timeout period (T1) according to the stored prediction condition, A GPS positioning unit 4 for performing a GPS positioning during a given timeout period T2 when the GPS positioning success determination unit 2 determines that the GPS positioning is possible and a GPS positioning success determination unit 2 A network-based positioning unit 5 for performing network-based positioning when it is determined that the GPS positioning is impossible, a condition storage unit 1, a GPS positioning success or failure determination unit 2, and a GPS positioning unit 4 ) And the network-based positioning unit 5 and performs the necessary processing Includes a control and processing unit (3). Here, the timeout time T1 is set to a timeout time T2.
Therefore, a condition (prediction condition) for predicting whether GPS positioning is possible in various terminals such as a PC, a mobile terminal and a security terminal (for example, four or more of the number of visible satellites and each satellite signal intensity is more than a certain level) If the timeout time T1 until the confirmation and the timeout time T2 of the GPS positioning operation are set, the prediction conditions and the timeout times T1 and T2 are stored in the condition storage unit 1 of the secure terminal do.
Now, the secure terminal receives a GPS positioning request through the location monitoring service, and the GPS positioning success / failure determination unit 2 determines the timeout time T1 and the prediction condition stored in the condition storage unit 1 when the GPS positioning starts It is determined within a timeout period T1 whether the number of visible satellites and the intensity of the satellite signal meet the above predictive condition.
If it is determined that the number of visible satellites is equal to or greater than 4 and the intensity of each satellite signal is equal to or greater than a certain level, it is determined that the GPS positioning is possible and the GPS positioning is performed through the GPS positioning unit 4 until the timeout period T2 do.
If it does not match or the timeout period T1 has elapsed, the GPS positioning is impossible or the timeout period T1 has elapsed. Therefore, the network-based positioning is immediately performed without performing the GPS positioning.
The operation sequence of the present invention will now be described with reference to FIG.
First, a timeout time T1 until a prediction condition is confirmed and a timeout time T2 of a GPS positioning operation are set (S1).
When the terminal receives the positioning request in the location monitoring service (S2) (the positioning request is performed by a request from a third party or a request by a voluntary self location information transmission service), the GPS positioning is started S3), and determines the number of visible satellites and the signal intensity during the timeout period T1 until the prediction condition is confirmed (S4).
As a result of the determination, if it is determined that the GPS positioning is successful, the process proceeds to step S5 to determine whether the GPS positioning is successful during the timeout period T2 of the GPS positioning operation (S5).
If it is determined that the GPS positioning is unsuccessful, the process proceeds to step S7 to immediately stop the GPS positioning, start the network-based positioning (S8), and provide the location information using the network-based positioning result S9).
If the GPS positioning is successful during the timeout period T2 of the GPS positioning operation in step S5, the flow advances to step S6 to provide position information using the GPS measurement result in step S6.
If the GPS positioning is not successful during the timeout period T2 of the GPS positioning operation in step S5, the flow advances to step S8 to start the network-based positioning (S8), and the network- And provides positional information (S9).
As a result, according to the present invention as described above, when the security terminal determines that the GPS receiver can perform GPS positioning, if it is determined that the GPS receiver is capable of GPS positioning, the GPS receiver continues the GPS positioning to provide the position information according to the GPS positioning, If the security terminal determines that the GPS positioning can not be performed at the location where the GPS terminal can not perform the positioning, the GPS positioning is immediately stopped and the network-based positioning is performed to provide the network-based position information.
Therefore, when the security terminal is located in a place where GPS positioning can not be performed, the GPS positioning is immediately stopped and the network-based positioning is performed, so that the position information providing time can be shortened (substantially shortened by T2-T1) It is possible to prevent the power consumption and the delay in providing the position information due to the GPS positioning attempt during the timeout period T2.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
