Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an example of a communication system usage situation according to an embodiment of the present invention.
As shown in FIG. 1, in one embodiment of the present invention, information is transmitted to a visitor via a communication terminal distributed by the facility to the visitor indoors such as an art museum or a museum. A surveillance camera (hereinafter sometimes referred to as a camera) is installed in the hall, and the image information obtained by shooting with this camera can be used.

Under such circumstances, the communication prohibited area, the low-speed communication area by Bluetooth communication, and the high-speed communication area by Wi-Fi communication are geographically set within the field of view of the camera, and the user is positioned based on the image information. Execute communication standard switching control according to the area to be used.

For example, when the user's position is in the low-speed communication area, the communication standard between the communication terminal carried by the user and the content distribution server (not shown) is Bluetooth communication, and the user's position is in the high-speed communication area. Sets the communication standard between the communication terminal carried by this user and the content distribution server as Wi-Fi communication, and when the user's position is within the communication prohibited area, the communication terminal carried by this user and the content distribution server Communication with is disabled.

Secure by using the above control to prohibit or limit communication in the aisle or outdoors, for example, allowing the communication terminal to communicate in the area in front of the work in the hall, for example, area A shown in FIG. It also makes it possible to create a comfortable data distribution environment.

In addition, by switching and controlling Wi-Fi communication, which has a high communication speed but high power consumption, to Bluetooth communication, which has a low communication speed but low power consumption, it is possible to achieve power saving of the communication terminal.

In one embodiment of the present invention, communication control using high-precision position estimation using a camera and precise communication area control are performed, respectively, to eliminate the trade-off between power saving and increase in content acquisition time.

FIG. 2 is a diagram showing a functional configuration example of the communication system according to the embodiment of the present invention. FIG. 3 is a diagram illustrating an example of a processing operation by the communication system according to the embodiment of the present invention.
As shown in FIG. 2, the communication system according to the embodiment of the present invention includes a communication control device 1, a camera 2, an access point (AP) 3, and a communication terminal (STA) 4.
The communication control device 1 includes an area setting control unit 11, a camera image processing unit 12, a terminal information processing unit 13, a terminal position estimation unit 14, and a terminal control determination unit 15.
The access point 3 has a terminal information acquisition unit 31 and a communication control unit 32. The communication terminal 4 has a state acquisition unit 41, a control determination unit 42, and a control unit 43.

In this communication system, access to information on a server (not shown) by the communication terminal 4 can be restricted as necessary based on the position information of the communication terminal 4.
The status acquisition unit 41 of the communication terminal 4 uses the application program mounted on the communication terminal 4 (communication execution) status, communication band usage (traffic) associated with the use of the application program, RSSI information, communication delay, and communication. Information indicating the sleep state of the RF unit (transmission / reception unit) in the terminal 4 (not shown) can be acquired as terminal information. The state acquisition unit 41 can transmit the acquired terminal information to the access point 3.

Based on the above acquisition result, the control determination unit 42 determines the content of the ON / OFF control of the sleep state of the communication terminal 4 and the control related to the increase / decrease in traffic by determining whether or not the bandwidth usage is equal to or higher than the threshold value. can.

Based on the determined content, the control unit 43 executes ON / OFF control of the sleep state of the communication terminal 4 and control related to traffic increase / decrease.

The terminal information acquisition unit 31 of the access point 3 acquires the terminal information transmitted from the communication terminal 4 and transmits this terminal information to the communication control device 1.
The terminal information processing unit 13 in the communication control device 1 converts the RSSI information indicated by the terminal information into a distance, and sends the information indicating this distance to the terminal position estimation unit 14.

The camera 2 constantly captures an image in the vicinity, and transmits the image information obtained by this imaging to the camera image processing unit 12 of the communication control device 1.
The camera image processing unit 12 recognizes the user carrying the communication terminal 4 from the image information transmitted from the camera 2, and sends the user recognition result to the terminal position estimation unit 14.

The area setting control unit 11 of the communication control device 1 sets an area design guideline based on the coordinates in the real space and the virtual space based on the operation by the administrator of the communication control device 1, and based on this guideline. , An area that allows access to a content distribution server (not shown) for content acquisition by the communication terminal 4 and an area that prohibits access are set, respectively. The area design guideline in the virtual space is a communication area design guideline based on the coordinates in the virtual space in which an arbitrary section is drawn on the camera image and this section is used as the area. If the above guidelines are changed, each area will be changed according to the changed guidelines.

The terminal position estimation unit 14 of the communication control device 1 calculates the estimated position of the communication terminal 4 based on the distance information sent from the terminal information processing unit 13. Further, the terminal position estimation unit 14 calculates the estimated position of the user based on the user recognition result sent from the camera image processing unit 12.

The terminal control determination unit 15 determines whether the terminal position and the user position estimated by the terminal position estimation unit 14 are within or outside the area set by the area setting control unit 11. Here, when it can be considered that the terminal position and the user position are the same, the terminal control determination unit 15 determines whether the user position is within the area set by the area setting control unit 11 based only on the user position. It may be determined whether it is outside. In this case, the time required for determination can be shortened. The terminal control determination unit 15 determines the control content regarding the ON / OFF control of the sleep state of the communication terminal 4 and the increase / decrease in traffic according to the determination result.

For example, when the user's position is outside the above-set area, the communication standard between the communication terminal 4 carried by the user and the content distribution server is set to Bluetooth communication, and the user's position is within the above-set area. In this case, the communication standard between the communication terminal 4 carried by this user and the content distribution server is Wi-Fi communication.
Further, instead of determining whether the user's position is inside or outside the set area, a plurality of types of areas are set, such as a low-speed communication area, a high-speed communication area, and a communication prohibited area, as described above. , The area to which the user's position belongs may be determined, and the control content may be determined according to the area to which the user's position belongs.

The determined control content is transmitted to the communication terminal 4 via the communication control unit 32 of the access point 3. The control unit 43 of the communication terminal 4 executes the control of the own terminal, the ON / OFF control of the sleep state, and the control related to the increase / decrease of traffic, according to the control content.

Further, in the present embodiment, the area setting control unit 11 of the communication control device 1 has the position estimated by the terminal position estimation unit 14, the control content determined by the terminal control determination unit 15, the area determination result, and the communication terminal 4. It is also possible to acquire the communication history of the above and automatically change the area based on the acquired contents so that, for example, the relationship between the area, the user position, and the control contents becomes appropriate.

As described above, the communication system according to the embodiment of the present invention uses the camera 2 to estimate the position of the user carrying the communication terminal 4. This estimated position is more accurate than the position of the communication terminal 4 estimated based only on terminal information such as RSSI information. Therefore, it is possible to realize communication control using Geo-Fencing technology by setting a minute area.
Further, by automatically setting the communication prohibition or permission area by the communication control device 1, it is possible to provide a flexible service.

Next, industrial utilization of the communication system according to the embodiment of the present invention will be described.
The communication system according to the embodiment of the present invention enables power saving of the communication terminal 4 by limiting the communication area by the communication terminal 4 to a place permitted by the system in a museum or a museum. .. This communication system is also applied in terms of realizing a content distribution environment limited to a specific area, preventing accidents due to warnings near passages or doorways, and ensuring security by limiting communication to a designated area in the hall. Wide.

Next, a specific example of the implementation by the communication system in one embodiment of the present invention will be described.
FIG. 4 is a diagram showing an example of a model of a proof-of-concept experiment applied to a communication system according to an embodiment of the present invention.
In the Proof-of-Concept experiment shown in FIG. 4, control is performed when the communication area is fixed. The control PC and the control AP can communicate with each other by a control line by 5G communication. Further, in this experiment, Wi-Fi communication and Bluetooth communication are assumed as communication standards to be mounted on the communication terminal 4 carried by the user.

In this experiment, a user carrying a controlled STA (corresponding to the communication terminal 4 shown in FIG. 1) in a room, and three APs (access points shown in FIG. 1) that monitor the status of the STA and control communication. Consider an environment in which a camera for monitoring the inside of the room (corresponding to the camera 2 shown in FIG. 1), a control PC, and a control AP exist (corresponding to 3). The communication control device 1 shown in FIG. 1 can be realized by the control PC and the control AP.

In this communication system, assuming an actual application mounted on the communication terminal 4, a communication recommended area, for example, a high-speed communication area where Wi-Fi communication is possible is provided, and the traffic of the communication terminal 4 is increased or decreased or increased or decreased in this area. RF section Performs activation control in the sleep state.

FIG. 5 is a diagram showing an example of detailed movement of a user in a model of a proof-of-concept experiment applied to a communication system according to an embodiment of the present invention.
In the example shown in FIG. 5, the user moves from time t = 0 [s] to 180 [s]. Assuming the movement shown in FIG. 5, the user enters the recommended communication area at time t = 45 [s] and exits the recommended communication area at time t = 135 [s]. The communication control device 1 estimates the terminal position from the image taken by the camera 2, monitors the movement of the user carrying the communication terminal 4, and executes the switching control of the communication standard.

Next, an example of experimental results expected when the communication system according to the embodiment of the present invention is used is shown.
First, the experimental results of traffic control will be described. FIG. 6 is a diagram showing an example of the result of performing traffic control using the communication system according to the embodiment of the present invention.
The conventional method of traffic control in the example shown in FIG. 6 is a position estimation method (conventional method) mainly composed of a communication control device using the above-mentioned BLE RSSI information, which is one of the 2.4 GHz band wireless standards, from a communication terminal. A). As shown in FIG. 6, the result of the traffic control by the Geo-Fencing method using a camera, which is applied to the communication system according to the embodiment of the present invention, shows that in the communicable area as compared with the conventional method A. The average throughput of communication terminals is significantly higher. This indicates that the communicable area setting is appropriate. That is, the Geo-Fencing method applied to one embodiment of the present invention enables traffic control according to a fine area setting.

Further, an example of the position estimation misrecognition rate in the Geo-Fencing method using a camera and the conventional method A applied to the communication system according to the embodiment of the present invention is shown in the following table. The position estimation erroneous recognition means that a place that should be determined to be inside the area is determined to be outside the area, and a place that should be determined to be outside the area is determined to be inside the area.

As shown in this table, compared to the Geo-Fencing method, the conventional method A has a large error in the position estimation misrecognition rate, that is, the position recognition accuracy, so it is difficult to realize indoor communication control for a small area. You can see that.

Next, the experimental results of power saving control will be described. Here, as a conventional method of power saving control, a conventional method A for performing position estimation using the above-mentioned BLE RSSI information and a method for performing control in the terminal based on the communication band usage status of the terminal (conventional method B). The experimental results are given by. Here, the result of the power consumption by the communication switching control and the content acquisition time by this control will be described respectively.

FIG. 7 is a diagram showing an example of the result of power consumption when power saving control is performed using the communication system according to the embodiment of the present invention.
As shown in FIG. 7, the Geo-Fencing method using a camera, which is applied to the communication system according to the embodiment of the present invention, is compared with the case where Wi-Fi communication is always turned on without performing communication switching control. The power saving property is excellent, but the power saving property is inferior to that of the conventional methods A and B. This is because when the camera 2 is used as in one embodiment of the present invention, the RF unit is turned on before the communication terminal 4 actually uses the application program, instead of the terminal-based control as in the conventional method B. This is because wasteful startup time is generated.
On the other hand, in the conventional method B, since the RF unit is turned on according to the band used by the communication terminal 4, the startup time of the RF unit can be suppressed to the minimum necessary.

FIG. 8 is a diagram showing an example of the result of the content acquisition time when power saving control is performed using the communication system according to the embodiment of the present invention. This result is the result of the content acquisition time when the communication terminal 4 starts acquiring the content when the communication standard before switching is Bluetooth communication. Further, here, the Geo-Fencing control using the camera according to the present embodiment is based only on the user position, and the user position is within or outside the area set by the area setting control unit 11. It shall be determined.

As shown in FIG. 8, in the present embodiment, the content acquisition time has the same performance as the case where the Wi-Fi communication is always turned on without performing the communication switching control. On the other hand, in the conventional method A, since the low-speed line by this Bluetooth communication is used for several seconds required for transmitting and receiving terminal information from the content acquisition start timing, the content acquisition time is longer than that of the present embodiment. Further, in the conventional method B, since the communication switching control is performed mainly by the communication terminal based on the traffic after the communication terminal 4 actually starts the communication, the content acquisition time is further longer than that in the conventional method A.

From the above, in the present embodiment, as compared with the conventional method, it is possible to realize communication control with finer area settings, achieve some power saving, and shorten the content acquisition time.

Here, an example of the area setting optimization formula will be described.
If the area size is too small, many communication terminals communicate with low throughput, which increases the content acquisition time. Further, if the area size is too large, many communication terminals communicate with each other with high throughput, so that the power consumption of the communication terminals increases.

Therefore, the power consumption of the communication terminal is _{set to P STA} , the area size set by Geo-Fencing is set to S _area , the content acquisition time is set to T _GetContent , and the required content acquisition time (for example, 2 [s]) is set to T. ^{* When} _GetContent is performed, the optimization formula for the area setting for reducing the content acquisition time to the required content acquisition time or less while suppressing the power consumption is as shown in (1) below.

min P _STA (S _area )… (1)
st T _GetContent (S _area ) ≤ T ^* _GetContent
