Background
In recent years, in order to improve the efficiency of use, more and more areas such as classrooms, office spaces, activity spaces, and the like are configurable according to the needs of users. For example, when it is desired to use a specific office area such as a conference room, many enterprises allow employees to make reservation registrations, and allow the employees making reservation registrations to use the specific office area at a reservation time. When users use these areas, it is often desirable to use not only the space resources of the area, but also the service resources in the space, for example, wireless networks, printers, projectors, and the like.
It has been proposed to provide means such as infrared, near field, etc. at the entrance of a specific area to determine whether a user enters a reserved area as reservation registration is made, and to allow the user to access a regional service resource when it is determined that the user enters the reserved area. However, the infrared device, the near field device, and the like are fixed in position, and it is inconvenient to flexibly adjust the boundary of the area to be used according to the user's needs. Furthermore, installation of infrared, near field, etc. devices increases the cost of configuring the area.

Detailed Description
In order that those skilled in the art will better understand the present invention, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Note that in the present specification and the drawings, steps and elements having substantially the same structure are denoted by the same reference numerals, and repeated explanation of the steps and elements will be omitted.
In an embodiment according to the invention, the terminal device and the reference device may be removable devices capable of transmitting wireless signals, e.g. WIFI signals, bluetooth signals, etc. Specific forms of terminal devices and reference devices may include, but are not limited to, mobile phones, portable computers, multimedia players, cameras, game consoles, and the like. Further, the access area may be an area in which a particular room in the floor is located. Further, in the embodiment according to the present invention, it is assumed that the terminal device is a device which has made a reservation and has an authority to use a service in the access area.
Fig. 1 is a flow chart describing an access control method according to one embodiment of the present invention. Next, an access control method 100 according to an embodiment of the present invention will be described with reference to fig. 1. As shown in fig. 1, in step S101, the location information of the terminal device is determined according to the signal characteristic value of the terminal device. And in step S102, it is determined whether the terminal device passes through the boundary of the access area to enter the access area based on the location information obtained in step S101. In an embodiment according to the present invention, the boundary of the access area may be determined according to a previously obtained signal characteristic value of the reference device.
The characteristic value may be one value or an array containing a plurality of values. For example, a signal characteristic value may be generated based on the strength of the transmitted signal. According to one example of the present invention, the RSSI (received signal strength indicator) of a signal transmitted by a terminal device or a reference device may be calculated as a signal characteristic value using a signal space attenuation model. For example, the RSSI of a signal transmitted by a device may be calculated by the following equation (1):
where n is the path loss index, d is the distance of the device, d0Is a reference distanceA is at a reference distance d0Reference RSSI of (c).
Further, for example, when the position information determined from the signal characteristic value of the terminal device matches the boundary of the access area determined from the signal characteristic value of the reference device obtained previously, it is determined that the terminal device has passed the boundary of the access area and entered the access area.
According to an example of the present invention, the access area may include one candidate area or may include a plurality of candidate areas. In particular, the candidate regions included by the access region may be determined based on region selection input from the user. Further, the physical location desired as the boundary of each candidate region may be determined in advance, the signal characteristic value of a reference device at the determined physical location may be measured and/or calculated, and the obtained signal characteristic value at the determined physical location may be taken as the boundary of the candidate region.
After determining the candidate regions that the access region includes based on the region selection input from the user, the boundaries of the access region may be generated based on the determined boundaries of the candidate regions. For example, when it is determined that the access region includes one candidate region according to the region selection input from the user, the boundary of the candidate region may be used as the boundary of the access region. For another example, when it is determined that the access region includes a plurality of candidate regions according to the region selection input from the user, a boundary located at the periphery of the composed access region among the boundaries of the plurality of candidate regions may be used as the boundary of the access region.
Further, according to another example of the present invention, the boundary of the access area may include a plurality of boundaries corresponding to each entry of the access area. In step S102, when it is determined that the terminal device passes through at least two boundaries of the plurality of boundaries of one entry of the access area in the predetermined order based on the position information, it is determined that the terminal device enters the access area. For example, the boundaries of the access area include at least an inner boundary provided at each entrance of the access area and an outer boundary on a path leading to the entrance. And when the terminal equipment is determined to pass through the outer boundary and then the inner boundary according to the position information, determining that the terminal equipment enters the access area. According to an example of the present invention, an entry to an access area and a path to the entry are predetermined valid entries and paths, and the number of valid entries and paths is limited.
An exemplary scenario for setting the boundaries of the access area according to an embodiment of the present invention will be further explained in connection with fig. 2a and 2 b. Fig. 2a is an explanatory diagram showing an exemplary case of setting a boundary of an access area according to an embodiment of the present invention. Fig. 2b is an explanatory diagram showing an exemplary case of setting a boundary of an access area according to another embodiment of the present invention. In the example scenario shown in fig. 2a and 2b, there is a first candidate area 210 and a second candidate area 250 in the floor 200. The first candidate region 210 has one entry and three paths may lead to the entry. The first candidate region 210 has one entry and three paths may lead to the entry. The second candidate region 250 has one entry and there are two paths to the entry. The inner boundary 211 of the first candidate region 210 is previously set at the entrance of the first candidate region 210 according to the signal characteristic value of the reference device at the entrance of the first candidate region 210, and the outer boundaries 212, 213, and 214 of the first candidate region 210 are respectively set at three paths near the entrance according to the signal characteristic values of the reference device at the three paths near the entrance. The inner boundary 251 of the second candidate region 250 is previously set at the entrance of the second candidate region 250 according to the signal characteristic value of the reference device at the entrance of the second candidate region 250, and the outer boundaries 252 and 253 of the second candidate region 250 are respectively set on two paths near the entrance according to the signal characteristic values of the reference device on the two paths near the entrance.
In the example shown in fig. 2a, the access region is determined to be the first candidate region 210 according to a region selection input from the user. In this case, the inner boundary 211 and the outer boundaries 212, 213, and 214 of the first candidate area 210 may be used as the boundaries of the access area. For example, as indicated by the dashed line 220 in fig. 2a, when it is determined from the location information that the terminal device passes the outer boundary 212 first and then the inner boundary 211, it is determined that the terminal device enters the access area 210.
Also in the example shown in fig. 2b, the access regions are determined to be the first candidate region 210 and the second candidate region 250 according to the region selection input from the user. In this case, it is preferable that,
the boundaries 212, 213, and 253 of the boundaries of the first candidate region 210 and the second candidate region 250, which are located at the periphery of the composed access region, may be used as the outer boundaries of the access region, the inner boundaries of the first candidate region 210 and the second candidate region 250 may be used as the inner boundaries of the access region, and the first candidate region 210 outer boundary 214 and the first candidate region 210 outer boundary 252 located inside the access region may not be used. When it is determined that the terminal device passes through one of the outer boundaries 212, 213, and 253 and passes through one of the inner boundaries 211 and 251 according to the location information, it is determined that the terminal device enters the access area.
It should be noted that although the example shown in fig. 2 illustrates an inlet having an inner boundary and an outer boundary, the present invention is not limited thereto. For example, intermediate boundaries can be directly arranged on the inner boundary and the outer boundary to further determine the moving mode of the terminal equipment.
Returning to fig. 1, when it is determined that the terminal device enters the access area, the terminal device is allowed to use the service in the access area in step S103.
Further, according to another example of the present invention, for each path to an access area, the path may be partitioned according to a signal characteristic value that the reference device previously had on the path. In step S101, a current block in which the terminal device is located may be determined among the divided blocks according to the signal characteristic value of the terminal device, and the current block may be used as the location information of the terminal device. Therefore, the position information of the terminal equipment can be obtained only by determining the block where the terminal equipment is located, and the accurate position information of the terminal equipment is not needed, so that the operation required for obtaining the position information of the terminal equipment is simplified.
In some cases, it may be desirable to prohibit any device from entering the access area from a path that is never valid, for security reasons. In this case, the terminal device may be further authenticated by the trace. Specifically, the movement trajectory of the terminal device may be determined from the position information. As described above, the movement trajectory of the terminal device may be generated according to the current block in which the terminal device is located.
For example, the proximity of the terminal to each tile may be determined by matching. When the user carrying the terminal device travels and sequentially passes through each block, the sequence of characteristic values of the signal transmitted by the terminal device can be recorded, and the moving track of the terminal device, namely the block in which the terminal device appears at a specific moment, can be roughly judged through the sequence. Preferably, the signal characteristic value corresponding to each block may be an array including a plurality of values to provide higher determination accuracy.
In step S103, when it is determined that the movement trajectory matches one of the paths to the access area and the terminal device enters the access area, the terminal device is allowed to use the service in the access area. For example, when it is determined that the movement trajectory passes through all blocks on a path, it may be determined that the movement trajectory matches the path. Alternatively, when it is determined that the number of matches of the movement trajectory with the patches on one path exceeds a predetermined threshold, it may be determined that the movement trajectory matches the path.
Further, according to another example of the present invention, the method illustrated in fig. 1 may further include determining whether the terminal device leaves the access area according to the location information, and prohibiting the terminal device from reusing the service in the access area when it is determined that the terminal device leaves the access area.
In the above access control method provided according to the embodiment of the present invention, by determining the boundary of the access area according to the signal characteristic value of the reference device previously at the boundary and determining whether the terminal device enters the predetermined access area according to the boundary and the location information of the terminal device determined based on the signal characteristic value of the terminal device, the boundary of the access area can be flexibly accessed, and it is not necessary to provide infrared, near field, or the like at the entrance of a specific area, thereby saving expenses.
Next, an access control device according to an embodiment of the present invention will be described with reference to fig. 3. Fig. 3 is a block diagram illustrating an exemplary structure of an access control apparatus 300 according to an embodiment of the present invention. As shown in fig. 3, the access control device 300 of the present embodiment includes a location acquisition unit 310, an area entry determination unit 320, and a service providing unit 330. The access control device 300 may perform the various steps/functions of the access control method 100 of fig. 1 described above, respectively. Therefore, only the main components of the access control device 300 are described below, and details that have been described above in connection with fig. 1 are omitted.
Specifically, the location acquisition unit 310 determines the location information of the terminal device according to the signal characteristic value of the terminal device. And the area entry determination unit 320 determines whether the terminal device passes through the boundary of the access area to enter the access area according to the location information obtained by the location acquisition unit 310. In an embodiment according to the present invention, the boundary of the access area may be determined according to a previously obtained signal characteristic value of the reference device.
For example, the characteristic value may be one value or an array containing a plurality of values. Signal characteristic values may be generated based on the transmitted signal strength. According to one example of the present invention, the RSSI (received signal strength indicator) of a signal transmitted by a terminal device or a reference device may be calculated as a signal characteristic value using a signal space attenuation model. For another example, when the location information determined from the signal feature value of the terminal device matches the boundary of the access area determined from the signal feature value of the reference device obtained previously, the area entry determination unit 320 may determine that the terminal device passes through the boundary of the access area and enters the access area.
According to an example of the present invention, the access area may include one candidate area or may include a plurality of candidate areas. Specifically, the region entry determining unit 320 may determine a candidate region included in the access region according to a region selection input from the user. Further, the access control device 300 may determine in advance a physical location desired as a boundary of each candidate region, measure and/or calculate a signal characteristic value of a reference device at the determined physical location, and regard the obtained signal characteristic value at the determined physical location as the boundary of the candidate region.
After determining a candidate region included in the access region according to a region selection input from the user, the region entry determining unit 320 may generate a boundary of the access region according to the determined boundary of the candidate region. For example, when it is determined that the access region includes one candidate region according to the region selection input from the user, the region entry determining unit 320 may take the boundary of the candidate region as the boundary of the access region. For another example, when it is determined that the access region includes a plurality of candidate regions according to the region selection input from the user, the region entry determining unit 320 may set, as the boundary of the access region, a boundary located at the periphery of the composed access region among the boundaries of the plurality of candidate regions.
Further, according to another example of the present invention, the boundary of the access area may include a plurality of boundaries corresponding to each entry of the access area. The area entry determining unit 320 may determine that the terminal device enters the access area when it is determined that the terminal device passes through at least two boundaries of the plurality of boundaries of one entry of the access area in a predetermined order based on the location information. For example, the boundaries of the access area include at least an inner boundary provided at each entrance of the access area and an outer boundary on a path leading to the entrance. When it is determined that the terminal device passes through the outer boundary and then passes through the inner boundary according to the location information, the area entry determining unit 320 determines that the terminal device enters the access area. According to an example of the present invention, an entry to an access area and a path to the entry are predetermined valid entries and paths, and the number of valid entries and paths is limited.
When it is determined that the terminal device enters the access area, the service providing unit 330 allows the terminal device to use the service in the access area.
Further, according to another example of the present invention, the access control device 300 may further include an area division unit. For each path to the access area, the area dividing unit may block the path according to a signal characteristic value of the reference device previously on the path. The location obtaining unit 310 may determine, from the signal feature value of the terminal device, a current block in which the terminal device is located in the divided blocks, and use the current block as the location information of the terminal device. Therefore, the location obtaining unit 310 can obtain the location information of the terminal device only by determining the block where the terminal device is located, and does not need to obtain the accurate location of the terminal device, thereby simplifying the operation required for obtaining the location information of the terminal device.
In some cases, it may be desirable to prohibit any device from entering the access area from a path that is never valid, for security reasons. In this case, the terminal device may be further authenticated by the trace. Specifically, the access control apparatus 300 may further include a trajectory determination unit to determine a movement trajectory of the terminal device according to the location information. As described above, the trajectory determination unit may generate the movement trajectory of the terminal device according to the current block in which the terminal device is located.
For example, the trajectory determination unit may determine the proximity of the terminal to each tile through matching. When the user carrying the terminal device travels and sequentially passes through the respective blocks, the trajectory determination unit may record a sequence of characteristic values regarding the signal transmitted by the terminal device, and roughly determine, from the sequence, a movement trajectory of the terminal device, i.e., at which block the terminal device appears at a specific time. Preferably, the signal characteristic value corresponding to each block may be an array including a plurality of values to provide higher determination accuracy.
The service providing unit 330 allows the terminal device to use the service in the access area only when it is determined that the movement trajectory matches one of the paths to the access area and the terminal device enters the access area. For example, the service providing unit may determine that the movement trace matches a path when determining that the movement trace passes through all blocks on the path. Alternatively, when it is determined that the number of the movement trajectory matching the patches on one path exceeds a predetermined threshold, the service providing unit may determine that the movement trajectory matches the path.
Further, according to another example of the present invention, the area entry determination unit 320 may also determine whether the terminal device leaves the access area according to the location information, and the service providing unit 330 prohibits the terminal device from reusing the service in the access area when it is determined that the terminal device leaves the access area.
In the access control apparatus provided above according to the embodiment of the present invention, by determining the boundary of the access area from the signal characteristic value of the reference device previously at the boundary and determining whether the terminal device enters the predetermined access area from the boundary and the location information of the terminal device determined based on the signal characteristic value of the terminal device, the boundary of the access area can be flexibly accessed, and it is not necessary to provide infrared, near field, or the like at the entrance of a specific area, thereby saving expenses.
