≪ Desc / Clms Page number 1 > METHOD AND APPARATUS FOR PROVIDING WIRELESS LOCATION SERVICE BASED ON HYBRID &

Embodiments of the present invention are directed to techniques for determining a user's current location using a beacon and a wireless access point and providing a location based service based on the user's current location.

The wireless positioning service is a technique for measuring the location of a user to provide location-based services (LBS) based on the user's current location. The location-based service provides services such as indoor maps based on the location of a smart phone, a PDA, a tablet PC, etc. located in the building using GPS, Wi-Fi (WIFI)

However, in the case of GPS and Wi-Fi, there is a difficulty in providing an appropriate location-based service because the position error of the terminal measured inside the building is large.

For example, when a user is located in an elevator or an escalator used for interlayer movement inside a building, the position of the user on the indoor map is erroneously displayed. In the case of an elevator, since there is no wall between the layers, the entire WiFi signal spreads all over the floor because it is pierced by one passage throughout the floor. As a result, when the user moves from the second floor to the fifth floor and descends from the elevator, the user's position is displayed as two floors even though the floor is the fifth floor. In addition, even if the user is not moved to the elevator and is located around the elevator on the fifth floor, the position of the user is displayed differently, such as the second floor, the third floor, and the like.

As described above, since the position of the user is erroneously determined due to the characteristic that the Wi-Fi signal travels between the layers, the location-based service corresponding to the wrongly determined position is provided to the user. For example, a user is located in a shop around a five-story elevator, and a location-based service corresponding to a wrong location, such as an indoor map on the second floor or a POI on the second floor, is provided to the user.

Accordingly, there is a need for a technique for providing a location based service by more precisely measuring the location of a user even if the user is located in the vicinity of an interlayer movement or interlayer movement providing means (for example, an elevator, an escalator, etc.).

There is provided a method and an apparatus for providing a wireless positioning service that more precisely measures a position of a user by using a beacon signal in a space where a WiFi signal is poorly received or a positioning error occurs such as an escalator or an elevator.

There is provided a method and an apparatus for providing a wireless positioning service for controlling a state of a Wi-Fi module and a Bluetooth module to be ON or OFF according to a position of a user terminal in a building to reduce battery consumption.

There is provided a method and an apparatus for providing a detailed positioning route of a user using a gyro sensor.

In one embodiment of the present invention, a method of providing a wireless positioning service performed by a wireless positioning service system including an information receiving unit, a positioning unit, and a service providing unit includes the steps of: Receiving a beacon signal and a wireless access point signal collected from peripheral beacon transmitters and wireless access points, and transmitting the beacon signal and the wireless access point signal from the beacon transmitters and the wireless access points using at least one of the beacon signal and the wireless access point signal, Determining a location, and in the service provisioning, providing a location-based service based on the user's current location to the user terminal.

In an embodiment of the present invention, the wireless positioning service system may be configured such that, in the information receiving unit, via the application installed in the user terminal, beacon signals collected from beacon transmitters and wireless access points located around the user, A positioning unit for determining a current position of a user by using at least one of the beacon signal and the wireless access point signal in the positioning unit; Based service to the user terminal.

According to an embodiment of the present invention, a file distribution system for distributing an installation file for installing an application to a user terminal includes an installation file management unit for storing and managing the installation file, Wherein the application collects wireless access point signals transmitted from a wireless access point located in the vicinity of the user and transmits the wireless access point signals located around the beacon transmitter to the collected wireless access point signals If the signal transmitted from the wireless access point is included, the beacon signal may be used to control the user terminal to receive the location based service based on the determined current location of the user.

In one embodiment of the present invention, a wireless location service system comprises: a signal collector for collecting wireless access point signals transmitted at a wireless access point located around a user; And a service providing unit for providing the location based service based on the current location of the user determined by using the beacon signal when the signal transmitted from the wireless access point including the wireless access point is included.

In a space where a WiFi signal is poorly received, or a positioning error such as an escalator or an elevator is largely generated, a beacon signal can be used to more precisely measure the position of the user.

The battery consumption can be reduced by controlling the states of the Wi-Fi module and the Bluetooth module to be ON or OFF according to the position of the user terminal in the building.

By providing the location based service using the gyro sensor of the user terminal, the detailed movement route of the user can be provided.

In addition, if there is a Wi-Fi transmitter in the vicinity of the beacon transmitter, the user terminal 103 may receive both the beacon signal and the Wi-Fi signal. For example, if there is a Wi-Fi transmitter within a predetermined reference radius based on the beacon transmitter, or if a beacon transmitter is installed in the Wi-Fi transmitter, the user terminal 103 may receive both the beacon signal and the Wi-Fi signal.

The wireless positioning service system 100 may provide the user with a wireless positioning service based on a beacon signal or a WiFi signal.

2 is a diagram illustrating a beacon transmitter and a wireless access point disposed within a building in an embodiment of the present invention.

The wireless access points may be placed at regular intervals in the passageways within the building and may be located within each store within the building and the beacon transmitters may be located in an underground parking lot, elevator, escalator or the like of the building. A plurality of wireless access points are arranged than the beacon transmitters and the beacon transmitter is arranged to provide wireless positioning and location based services in a shadow area (e.g., a parking lot, an elevator, an escalator, etc.) .

2, for example, the beacon transmitters B may be arranged in a manner such that the elevator surrounding places inside the building (for example, the ceiling of the corresponding floor where the elevator is located), the place where the escalator starts, Place, and where the escalator ends.

For example, if the ascending escalator ascends from the first floor to the second floor, the beacon transmitter 201 is placed in a facility near the escalator on the first floor where the escalator starts (for example, a counter, a pillar, a shelf, A beacon transmitter 202 is disposed at an intermediate position of the escalator such as a billboard, and a beacon transmitter (not shown) is installed in a facility near a two-story escalator in which an escalator ends (for example, 3 203 may be disposed.

And, at least one wireless access point may be disposed around the beacon transmitter. For example, wireless access point 1 (204) is disposed around beacon transmitter 1 (201), wireless access point 2 (205) and wireless access point 3 (206) are disposed around beacon transmitter 3 (203) Wireless access point 4 (208) may be located around beacon transmitter 4 (207).

FIG. 4 is a block diagram illustrating an internal configuration of a radio positioning service system in an embodiment of the present invention, and FIG. 5 is a flowchart illustrating a radio positioning service method in an embodiment of the present invention.

The wireless positioning service system 400 according to the present embodiment may include a processor 410, a bus 420, a network interface 430, and a memory 440. The memory 440 may include an operating system 441 and a wireless location service providing routine 442. The processor 410 may include an information receiving unit 411, a positioning unit 412, and a service providing unit 413. In other embodiments, the wireless location service system 400 may include more components than the components of FIG. For example, the wireless location service system 400 may include other components such as a display or a transceiver.

The memory 440 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. Also, the memory 440 may store program codes for the operating system 441 and the wireless positioning service providing routine 442. [ These software components may be loaded from a computer readable recording medium separate from the memory 440 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 440 via the network interface 430 rather than from a computer readable recording medium.

The bus 420 may enable communication and data transmission between components of the wireless location service system 400. [ The bus 420 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or any other suitable communication technology.

The network interface 430 may be a computer hardware component for connecting the wireless location service system 400 to a computer network. The network interface 430 may connect the wireless location service system 400 to a computer network via a wireless or wired connection.

Processor 410 may execute a wireless positioning service provisioning routine stored in memory 440 to determine the user's current location within the building in which the user is located and to provide location based services based on the current location.

The processor 410 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations of the wireless location service system 400. The instructions may be provided by the memory 440 or network interface 430 and to the processor 410 via the bus 420. The processor 410 may be configured to execute program codes for the information receiving unit 411, the positioning unit 412, and the service provider 413, and such program codes may be stored in a recording device such as the memory 440 Lt; / RTI >

The information receiving unit 411, the positioning unit 412, and the service providing unit 413 may be configured to perform the steps 510 to 550 of FIG. Hereinafter, a case where a wireless positioning is provided based on a wireless access point signal (for example, a Wi-Fi signal) to provide a wireless positioning by mixing a wireless access point signal and a beacon signal will be described.

In step 510, the information receiving unit 411 can receive a wireless access point signal through an application installed in the user terminal 103. [ At this time, the user terminal 103 may collect wireless access point signals from at least one wireless access point located around the user among a plurality of wireless access points disposed inside the building.

For example, if the user moves through an in-building passageway or is located around an escalator, the user terminal 103 may receive a Wi-Fi signal transmitted from Wi-Fi transmitters located around the user via the Wi-Fi module. The Wi-Fi signal may include a MAC address, which is identifier information of a Wi-Fi transmitter.

In step 520, the positioning unit 412 can check whether at least one signal received from the user terminal 103 includes a signal transmitted from a Wi-Fi transmitter located in the vicinity of the beacon transmitter.

For example, in building an indoor map of a building in advance, Wi-Fi transmitters located around the beacon transmitters among the Wi-Fi transmitters located within the building can be known in advance. That is, the MAC addresses of the Wi-Fi transmitters located around the beacon transmitters can be established. The positioning unit 412 can check whether the MAC address of the Wi-Fi signals received through the application installed in the user terminal 103 matches the MAC address of the Wi-Fi transmitter located around the beacon transmitter.

In the case of matching (520: YES), the positioning unit 412 can control the application to change the operating state of the Bluetooth module of the user terminal 103 to the ON state. Then, the user terminal 103 may collect the beacon signal transmitted from the at least one beacon transmitter through the Bluetooth module, and provide the collected beacon signal to the wireless positioning system 100 through the application.

In step 530, the position determination unit 412 may determine the current position of the user based on the beacon signal. For example, the positioning unit 412 may stop the operation of determining the user's current position based on the Wi-Fi signal, and may determine the current position of the user based on the beacon signal.

In step 540, the service provider 413 may provide location based services based on the user's current location. For example, the service provider 413 may provide an indoor map such as a route guide based on the user's current location in the building, or provide an event corresponding to each store in the building, coupon discount information, etc. Can be provided.

If the MAC address of the Wi-Fi signals does not match the MAC address of the Wi-Fi transmitter located in the vicinity of the pre-stored beacon transmitter (520: NO), the position determination unit 412 determines, based on the Wi- (550). ≪ / RTI > The service providing unit 413 may provide the location based service based on the current location of the user.

For example, if not matched, the positioning unit 412 can continue to provide wireless positioning based on the Wi-Fi signal. At this time, the positioning unit 412 confirms the operation state of the Bluetooth module through the application installed in the user terminal 103, and controls the operation of the user terminal 103 so that the operation state of the Bluetooth module is turned off Can be controlled.

For example, when the operating state of the Bluetooth module is ON, the positioning unit 412 can change the operating state of the Bluetooth module to OFF through the application. For example, if the user moves from the first floor to the second floor with the escalator and then walks the second floor inner passage, the operating state of the Bluetooth module may be ON. Thereafter, when the user moves the second floor inner path and there is no beacon transmitter around the user, it is no longer necessary to keep the operating state of the Bluetooth module ON. Then, the positioning unit 412 can change the operation state of the Bluetooth module to the OFF state, thereby saving battery consumption.

As another example, when the operating state of the Bluetooth module is OFF, the positioning unit 412 can control the user terminal 103 through the application so that the operating state of the Bluetooth module remains OFF have.

Figure 6 is a flow diagram illustrating a detailed operation for performing a wireless positioning based on a beacon signal in one embodiment of the present invention.

6, each of the steps 610 to 630 may be performed by the information receiving unit 411, the positioning unit 412, and the service providing unit 413.

Referring to FIG. 6, the information receiving unit 411 may receive a Wi-Fi signal transmitted from a Wi-Fi transmitter located in the vicinity of the beacon transmitter.

In operation 610, the positioning unit 412 may change the operation state of the Bluetooth module to the ON state through the application installed in the user terminal 103.

The user terminal 103 may collect the beacon signal transmitted from the beacon transmitter through the Bluetooth module.

In operation 620, the information receiving unit 411 may receive the beacon signal collected from the user terminal 103 through the application.

In step 630, the positioning unit 412 determines which of the beacon signal and the Wi-Fi signal is to be used to provide the wireless positioning based on the level of the beacon signal (for example, the signal strength of RSSI or the like) Can be determined.

For example, if the level of the received beacon signal is higher than the reference level (630: YES), the positioning unit 412 stops the Wi-Fi-based positioning that was previously used for the wireless positioning, The position can be determined. As the user is located close to the beacon transmitter, such as by being located around the elevator or boarding an elevator, the level of the received beacon signal (RSSI) can be large. Since the WiFi signal is not well received due to the interlayer movement characteristic of the WiFi signal in the vicinity of the elevator, the error of the wireless positioning using the WiFi signal may become large. Accordingly, when the level of the beacon signal is equal to or higher than the reference level, the positioning unit 412 determines the current position of the user more accurately by using the beacon signal instead of the Wi-Fi signal, and can provide a more accurate location-based service.

If the level of the received beacon signal is smaller than the reference level (630: NO), the user may move to the destination after getting off the elevator or escalator rather than boarding the elevator or escalator. Accordingly, the positioning unit 412 can repeat the process of checking whether the collected Wi-Fi signal is transmitted from a Wi-Fi transmitter located around the beacon transmitter, Can be determined.

7 is a diagram provided for explaining an operation of performing a wireless positioning based on a beacon signal, in an embodiment of the present invention. Fig. 7 is a view for explaining the assumption that the user moves on the escalator in the upward direction, but the same method can also be applied when moving in the downward direction other than the upward direction.

7, when a user moves inside a building from wireless access point 1 701 to wireless access point 3 703, when a user moves between wireless access point 1 701 and wireless access point 2 702 The user terminal 103 may receive a Wi-Fi signal from the wireless access points 1 and 2 (701, 702). The information receiving unit 411 can receive the Wi-Fi signal collected by the user terminal 1020 through the application. The positioning unit 412 determines the current position of the user based on the received Wi-Fi signal, The study 413 may provide location based services based on the current location of the determined user.

At this time, when the user moves from the wireless access point 2 702 to the third wireless terminal 703, the user terminal 103 receives the Wi-Fi signals transmitted from the wireless access points 2 and 3 702 and 703, To the information receiving unit 411. The positioning unit 412 can confirm that the beacon transmitter 1 704 is located in the vicinity based on the MAC address of the Wi-Fi signal received from the wireless access point 3 (703). Then, the positioning 412 can control the user terminal 103 such that the operating state of the Bluetooth module is changed to the ON state. When the Bluetooth module is turned on, the user terminal 103 can receive a beacon signal from the beacon transmitter 1 704. [ If the user is away from the beacon transmitter 1 704 simply past the escalator or past the store near the escalator without boarding the escalator, the level of the received beacon signal may be below the reference level. Then, the positioning unit 412 determines the current position of the user based on the Wi-Fi signal, and controls the user terminal 103 such that the operating state of the Bluetooth module is turned off.

On the other hand, when the level of the beacon signal 1 received from the beacon transmitter 1 704 is equal to or higher than the reference level, the user terminal 103 acquires the beacon signal 2 from the beacon transmitter 2 705, The positioning unit 412 can determine that the user is moving in the direction from the first floor to the second floor with the escalator. For example, the positioning unit 412 can confirm that the signal transmitted from the beacon transmitter 1 disposed around the escalator of the first floor is received based on the MAC address of the beacon transmitter 1. In the same way, based on the MAC addresses of the beacon transmitters 2 and 3, the positioning unit 412 receives the signals transmitted from the beacon transmitter 2 disposed on the billboards surrounding the escalator between the first and second layers, It can be confirmed that the signal transmitted from the beacon transmitter 3 disposed in the vicinity is received. The positioning unit 412 can determine that the user is moving in the ascending direction from the beacon transmitter 1 704 to the beacon transmitter 3 705 by ascertaining the escalator.

In addition to the MAC address of the beacon signal, the positioning unit 412 can determine that the user is moving in the upward direction of the escalator based on the strength of the signal. For example, when a user moves from the first floor to the second floor by boarding the escalator, the strength of the beacon signal 1 received from the beacon transmitter 1 704 gradually weakens, and then the beacon signal 1 received from the beacon transmitter 2 The intensity of the beacon signal 2 is again weakened and the intensity of the beacon signal 3 received from the beacon transmitter 3 706 may be intensified. As described above, the positioning unit 412 can determine that the user is moving from the first floor to the second floor in the escalator through the change in RSSI of the beacon signal.

At this time, the user may move from the first floor to the second floor by taking the escalator, and then move to the destination of the second floor by taking the escalator, or may move to the third floor, the fourth floor and so on. The user terminal 103 continues to collect the beacon signal from the beacon transmitters installed in the vicinity of the escalator and provides the beacon signal to the information receiving unit 411. The position determining unit 412 determines the beacon signal based on the beacon signal It can be determined that the user is moving to the third, fourth, and so on.

If the user moves down from the second floor, the signal level of the beacon transmitter 3 706 is higher than the reference level until the user gets off the beacon. However, when the user moves toward the destination after the beacon, . When the beacon transmitter 3 706 has a signal level lower than the reference level and a Wi-Fi signal is received from the wireless access points 4 707 and 5 708, the positioning unit 412 determines the operation state of the Bluetooth module And can determine the current location of the user based on the Wi-Fi signal received from the wireless access points 4 (707) and 5 (708).

At this time, the user can get off the second floor and turn to the left, right, etc., and move toward the destination. In this way, when the user turns the direction, the gyro sensor mounted on the user terminal 103 can sense the direction change of the user.

For example, the service provider 413 receives the rotation angle and the step counter detected by the gyro sensor through the application in accordance with the direction change of the user, and determines whether the user has been rotated based on the received rotation angle and the step counter Can be determined. The service provider 413 can confirm that the user has rotated 30 degrees, 45 degrees, 90 degrees or the like even if the reference point is not known through the gyro sensor. Then, the service providing unit 413 can reflect the change in the position as the user switches the direction to the left or right direction, or the user changes the direction at the pathway, intersection, etc. inside the building, directly on the indoor map. For example, the service provider 413 can rotate the indoor map on the basis of the direction in which the user has switched and provide the indoor map to the user.

7, it is described that the service provider 413 reflects the change of direction of the user detected by the gyro sensor on the indoor map. However, the direction of the user is reflected on the indoor map by the user terminal 103 And display it. For example, the user terminal 103 can determine whether or not the user has been rotated based on the rotation angle detected by the gyro sensor and the step counter. The user terminal 103 can rotate and display the indoor map on the basis of the determined turning movement value. The operation of providing the detailed movement path of the user using the gyro sensor will be described later with reference to FIG.

8 is an exemplary diagram for explaining an operation of providing a detailed movement path of a user using a gyro sensor in an embodiment of the present invention.

In the interior of the building, there are many structures that affect the magnetism such as sewage pipe, electric wiring, etc. Therefore, the magnetic properties of the north, south, east and west are all different. When a compass determines a user's direction (for example, north, south, east, and west) indoors, the error is so great that a completely different direction is determined for the user's direction. Accordingly, in this embodiment, the operation of using the gyro sensor and the beacon to accurately determine the direction of the user in the room will be described with reference to FIG. For example, if you use a gyro sensor, you do not know the direction of north, south, east, but you can see how much it is based on the sensing value. By using the beacon transmitter and the wireless access point, the reference point can be known. Then, it can be confirmed that the radio positioning service system generates a direction change of 90 degrees or 180 degrees based on the reference point. That is, the radio positioning service system can determine not only the rotation angle but also the rotation direction.

Referring to FIG. 8, when a user having a user terminal 103 such as a smart phone moves inside the building, rather than constantly moving the center of the passageway, the user can view the products displayed on the shops on both sides, Move away from people and move to the left, right, etc. to the destination. In addition, the user moves through the interlayer through a moving means such as an elevator or an escalator, and then moves to a destination. In this way, when moving to the destination, the wireless positioning service system 400 can reflect the detailed travel route 801 of the user on the indoor map by using the gyro sensor and provide it to the user terminal 103. The direction that is changed according to the detailed movement of the user may be reflected on the indoor map, and the map may be rotated and provided to the user.

For example, when the user moves from the escalator to the left after moving to the left, the gyro sensor 450 can immediately detect that the 90 degree rotation movement has occurred. At this time, the user terminal 103 collects a Wi-Fi signal from the wireless access point 1 802 until the rotation movement detection time, and collects the Wi-Fi signal from the wireless access point 2 (803) can do.
