Description

SYSTEM AND METHOD FOR GEO-FENCE ESTABLISHMENT

The present invention relates to a geofence building system and method, and more particularly, to a geofence building system and method, in which a location provider is changed based on a priority or a density of POIs based on a current location, To a geofence building system and method for constructing a fence.

Geofence refers to a system in which a user enters or departs within a predetermined radius based on POI (Point of Interest).

When the client sends the current location to the server, the server delivers the neighboring POI information to the client based on the received location. Then, the client builds a geofence based on the corresponding POI information, and confirms whether each geofence is entered or departed based on the currently set location provider.

However, conventionally, since the location provider is not changed dynamically according to the density or importance of the POI, if the error rate of the current location provider is high, the accuracy is not guaranteed and even if the geographical fence is not entered or departed, there is a problem. For example, in the case of a busy street such as Myeongdong, it can be seen that the POI data to be used are concentrated. Since the distance of each POI is usually 3 to 4 meters, most of the location providers provided by the client are unreliable when measured by Cell or WIFI with a larger error range.

In addition, when moving to the boundary of the received POI information group, the client must request the server to receive the new POI information group, and the POI information group in the region which is overlapped due to the low accuracy of the current location It has a drawback that it consumes low efficiency and unnecessary battery.

In addition, high accuracy location providers are highly reliable, but battery consumption is also proportionate. Therefore, if the POI around the current location is small, the error rate of entry or departure of Taji fence will be lowered, so there is no need for highly accurate location provider. At present, however, battery efficiency is low because no such dynamic location provider usage is applied.

The foregoing and other objects, features, and advantages of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

1 is a diagram illustrating a geofence building system according to an embodiment of the present invention.

Referring to FIG. 1, a geofence building system includes a terminal device 100 and a service device 200.

The terminal device 100 receives the POI information by transmitting the POI information request signal including the current location to the service device 200 and changes the location provider based on the priority or density of each POI included in the POI information, Build a fence. At this time, the terminal device 100 selects a global positioning system (GPS) as a location provider when the density is high, selects a location provider having the least battery consumption when the density is low, If a POI with a high priority is checked, the current location provider is checked. If the location provider is a low-reliability location provider, it is checked whether or not the user has actually entered the site through the GPS again. You can keep your location provider by GPS until you leave. Here, the location provider is an apparatus for locating and providing the current location of the terminal device 100, and may include, for example, a GPS, a base station, a Wi-Fi AP (Access Point)

The terminal device 100 is a device having a wireless communication function that the user can move and carry. Such a terminal device 100 can be applied to any user device including a communication function. For example, a navigation device, a notebook, a mobile communication terminal, a smart phone, a portable media player (PMP), a personal digital assistant (PDA), a tablet PC, a set- Smart TV and so on. Also, the terminal device 100 can recognize the current location of the terminal through a location positioning system (not shown), and can support location measurement with its own GPS module.

The terminal device 100 will be described in detail with reference to FIG.

When the POI information request signal including the location information is received from the terminal device 100, the service device 200 searches the POI database to extract POIs based on the location information, and extracts the density and importance of the extracted POIs And transmits the POI information having the priority set to the terminal device 100. [

The service device 200 will be described in detail with reference to FIG.

FIG. 2 is a block diagram schematically showing a configuration of a terminal device according to an embodiment of the present invention, and FIG. 3 is a detailed view of the geofence building unit shown in FIG.

2, the terminal device 100 includes a communication unit 110, an input unit 120, an output unit 130, a storage unit 140, a position measurement unit 150, a geofence building unit 160, (170).

The communication unit 110 communicates with the service device through a communication network. The communication unit 110 transmits a POI information request signal to the service device and receives POI information from the service device.

The input unit 120 is a means for receiving a user request for controlling the operation of the terminal device 100, and converts the request of the user into an electric signal according to a user's operation. The input unit 120 may be a keyboard, a keypad, a touch screen, a visual sensing unit, a tactile sensing unit, a motion sensing unit, , Voice input means, and the like.

The output unit 130 displays a geofence constructed based on the current location. The output unit 130 may be a form of a display that can be visually confirmed, a form that can be visually verified such as a speaker, or any other form capable of identifying a geofence.

The storage unit 140 stores a program necessary for controlling the operation of the terminal device 100 and data generated during the execution of the program.

The position measuring unit 150 measures the current position of the terminal device 100. The position measuring unit 150 can determine the current position through the position locating system, and can measure the position with its own GPS module. There are various positioning methods, such as a method of measuring the position using the cell information of the currently connected base station or the base station of the terminal 100, and a method of measuring the positional information using GPS satellites.

The geofence establishing unit 160 transmits a POI information request signal including the current position measured by the position measuring unit 150 to the service device through the communication unit 110. When the POI information is received from the service device, The geofence is constructed by changing the location provider based on the priority or density of the POIs included in the information.

That is, the geofence establishing unit 160 defines a dynamic geofence area for a location provider that is set based on the current location of the terminal device 100. The dynamic geofence area can be any polygon, most simply a circle. The dynamic geofenced area is defined for the location provider by selecting a specific geographic boundary for the location provider and thereby defining a dynamic geofenced area. The location provider may be any distance from the dynamic geofenced area including the interior of the dynamic geofenced area, the boundary of the dynamic geofenced area, or the outside of the dynamic geofenced area. One of the simplest arrangements for defining a dynamic geophone region for a location provider is to have the location provider at the center of the circle, which defines a dynamic geofenced area with a specified radius.

3, the geofence establishing unit 160 includes a POI information receiving module 162, a location provider changing module 164, and a geofence building module 166 .

The POI information receiving module 162 transmits the POI information request signal including the current location to the service device, and receives the POI information including the radius, priority, density, etc. of POIs from the service device. Here, the POI information request signal may include a current location, terminal device identification information, and the like.

The location provider change module 164 changes the location provider based on the priority or density included in the POI information received by the POI information reception module 162. [ That is, the location provider change module 164 may select GPS as a location provider when the density of POIs is high, and a location provider with the least battery consumption when the density of POIs is low. Here, when the density of the POIs is high, the POIs are dense at a predetermined density or more, and when the density of the POIs is low, the POIs are dense at a density lower than the reference density. Since the location provider is predetermined in order of the battery consumption in the order of GPS, WI-FI AP, etc., the battery consumption of the terminal device 100 is set in advance by the location provider change module 164, so that when the density of POIs is low, You can choose a small number of location providers.

In addition, the location provider change module 164 makes a measurement with the presently set location provider when a predetermined number of POIs having a high priority is low although the density of POIs is low, It is possible to check whether or not the provider has actually entered the site through the GPS in the case of a low-reliability location provider, and to maintain the GPS location provider until the exit when the user actually enters the site. At this time, since the location provider change module 164 is provided with the reliability value when the location information is provided from the location provider, it is possible to check the reliability of the current location provider, and if the reliability value is less than the preset reference reliability value, , It is confirmed whether or not the GPS has actually entered again to the side.

As described above, the location provider change module 164 uses a location provider with high reliability to improve the accuracy of geofence measurement when the POIs are configured with a higher density than the standard. In addition, the location provider change module 164 uses a medium reliability location provider to save battery power if the POIs are configured with less than standard density. In addition, the location provider change module 164 allows the high reliability POI to be measured with a high reliability location provider, thereby increasing the reliability of the geofenced system and the resource efficiency of the terminal device.

The geofence building module 166 builds a geofence using the location provider changed in the location provider change module 164.

The notification unit 170 notifies whether the geofence built in the geofence establishing unit 160 enters or leaves. At this time, the notification unit 170 can notify the entry or departure of the geofence by using a warning sound, a notification sound, or the like.

4, the service apparatus 200 includes a POI database 210, a location information receiving unit 220, a POI searching unit 230, a priority determining unit 240, and a POI information providing unit 250 .

The POI database 210 stores information on POIs. That is, the POI database 210 stores POI information including position, radius, density, importance, and priority of POIs.

The location information receiving unit 220 receives a POI information request signal including location information from a terminal device through a communication network.

The POI searching unit 230 searches the POI database 210 and extracts POIs based on the location information of the terminal. That is, the POI searching unit 230 extracts POIs included in the predetermined radius range around the position information from the POI database 210. At this time, all POIs included in the range are searched and extracted.

The priority definition unit 240 sets priorities of the POIs based on the density and importance of the POIs extracted from the POI search unit 230. That is, since the importance and density of each POI are stored in advance, the priority defining unit 240 identifies the priority of the POIs in order of importance, checks the importance of the extracted POIs, . At this time, the number of POIs to be extracted in priority order from the service manager or the terminal device can be set. That is, the priority definition unit 240 extracts POIs according to a predetermined number of priorities. Here, the importance is information set at POI establishment, for example, the importance of the medical institution can be set high and the importance of the clothing store can be set low. The importance may be a value set using a numerical value or the like.

The POI information providing unit 250 transmits the POI information having the priority set to the priority defining unit 240 to the terminal device. Here, the POI information may include the POI, the radius, the priority, the density of the POI group, and the like.
