In a system that detects a wireless tag and collects the information on the server side as in the technique of Patent Document 1, even if one mobile terminal scans or a plurality of mobile terminals scan. As long as you are scanning the same wireless tag, the effect will not change. Therefore, in such a case, only one mobile terminal needs to scan, the other mobile terminal wastefully scans, and the other mobile terminal consumes a lot of power. is there.

Therefore, an object of the present invention is to provide a terminal management device capable of appropriately controlling the scanning interval for a communication terminal that scans the same wireless tag.

In order to solve the above-mentioned problems, the terminal management device of the present invention identifies the tag IDs of a plurality of wireless tags from one or a plurality of communication terminals that detect the wireless tags at predetermined scan intervals. By comparing the receiving unit received together with the device ID for the device and the plurality of tag IDs of each of the plurality of communication terminals received by the receiving unit, the scan area for the wireless tag of the communication terminal is the same or Frequency of scanning processing for at least one communication terminal among the similar area determination unit that selects a plurality of communication terminals that form similar similar areas and the plurality of communication terminals selected by the similar area determination unit. It is provided with a control unit that controls the suppression of the noise.

For example, the control unit may control the scan interval of the communication terminal to be longer than the scan interval immediately before, or to instruct the stop of the scan for a predetermined time.

According to the present invention, a plurality of communication terminals forming a similar area, which is the same or similar scan area, are selected based on the received tag ID, and at least one communication among the selected plurality of communication terminals is performed. Control is performed to reduce the scanning frequency of the terminal, for example, to lengthen the scanning interval, or to instruct to stop scanning for a predetermined time. When a plurality of communication terminals form the same or similar scan area, the same wireless tag is scanned. Even if some communication terminals have a long scanning interval or are stopped for a predetermined time, if other communication terminals do not change the scanning interval, some communication terminals scan the wireless tag without changing the scanning accuracy. Can be done. Therefore, the battery consumption of other communication terminals can be reduced without changing the scanning accuracy of the entire system.

An embodiment of the present invention will be described with reference to the accompanying drawings. When possible, the same parts are designated by the same reference numerals and duplicate description is omitted.

FIG. 1 is a diagram showing a system configuration of a communication system using the service server 300 of the present embodiment. As shown in the figure, this communication system includes a mobile terminal 100, a fixed terminal 150, wireless tags 200a to 200d, and a service server 300. Although it is described as a single number in the figure, a plurality of mobile terminals 100 and fixed terminals 150 may exist.

The mobile terminal 100 and the fixed terminal 150 are communication terminals capable of scanning and detecting wireless tags 200a to 200d by short-range wireless communication such as Bluetooth. The mobile terminal 100 and the fixed terminal 150 transmit the detected tag IDs of the wireless tags 200a to 200d to the service server 300. The service server 300 can recognize that the mobile terminal 100 and the fixed terminal 150 form the same or similar scan area (similar area) based on the received tag ID. Area A in FIG. 1 shows a scan area of the mobile terminal 100, and Area B schematically shows a scan area of the fixed terminal 150. Since the detected wireless tags are the same, they are recognized as similar areas.

The usage scenes of the mobile terminal 100 include the following. The mobile terminal 100 transmits the tag ID of the wireless tag 200 existing around the mobile terminal 100 to the management server. As a result, the existence of wireless tags around it can be grasped on the management server side. For example, by giving the wireless tag 200 to a child, an elderly person, a pet, or the like, the management server can grasp where the user is. Such a mobile terminal 100 is owned by a general user.

FIG. 2 is a block diagram showing a functional configuration of the service server 300. As shown in FIG. 2, the service server 300 functions as a terminal management device that manages communication terminals such as the mobile terminal 100, and is a receiving unit 301, a terminal information storage unit 302, a similar area determination unit 303, and a terminal. It includes a determination unit 304 (control unit) and a notification unit 305.

FIG. 3 is a hardware configuration diagram of the service server 300. Physically, as shown in FIG. 3, the service server 300 shown in FIG. 2 includes one or a plurality of processors 1001, a memory 1002 as a main storage device, a storage 1003 such as a hard disk or a semiconductor memory, a network card, or the like. It is configured as a computer system including a communication device 1004, an input device 1005, an output device 1006 such as a display, etc., which are data transmission / reception devices. Each function in FIG. 2 operates the input device 1005, the output device 1006, and the communication device 1004 under the control of the processor 1001 by loading predetermined computer software on the hardware such as the memory 1002 shown in FIG. It is realized by reading and writing data in the memory 1002 and the storage 1003.

Hereinafter, each function will be described based on the functional block shown in FIG.

The receiving unit 301 receives scan information including a scan result (tag ID), a device ID, a scan date and time (year, month, day, hour, minute, second), and an estimated remaining operation time from a mobile terminal 100 or a fixed terminal 150 via a network. This is the part to receive.

The terminal information storage unit 302 is a unit that stores scan information received by the reception unit 301.

FIG. 4 is an explanatory diagram of a scan information table stored in the terminal information storage unit 302. As shown in FIG. 4, the scan information table stores the device ID, the tag ID, the scan date and time, and the estimated remaining operation time in association with each other. The device ID is an ID indicating the mobile terminal 100 or the fixed terminal 150. The tag ID is an ID of a wireless tag scanned and detected by the mobile terminal 100 or the fixed terminal 150. The scan date and time is the date and time when the mobile terminal 100 or the fixed terminal 150 scans. The estimated remaining operating time indicates the operating time calculated based on the remaining battery level of the mobile terminal 100. The remaining operating time may be used instead of the remaining operating time.

The similar area determination unit 303 forms a scan area having the same or similar tag ID based on the scan information stored in the terminal information storage unit 302 each time the scan information is received by the reception unit 301. This is a part for determining and extracting the terminal 100 and the fixed terminal 150.

Taking FIG. 3 as an example, in the similar area determination unit 303, since the tag IDs of the device IDs aaa and bbb all match, these mobile terminals 100 (or fixed terminals 150) have the same or similar scan areas (similar). It is extracted as forming an area). Even if the tag IDs are partially different, it may be determined as a similar area as long as it is within a predetermined number or matching ratio.

Further, the similar area determination unit 303 has a similar area management table that manages terminal IDs that form similar areas. FIG. 5 shows a specific example of the similar area management table. As shown in the figure, the group and the terminal ID are stored in association with each other. Here, the terminal ID: aaa and the terminal ID: bbb are managed as forming a similar area.

The similar area determination unit 303 determines whether or not the mobile terminal 100 that has transmitted the scan information using the similar area management table is already forming a similar area. If a similar area is being formed, it is determined based on the scan information table whether or not the tag ID has been changed. If the similar area is not being formed, the similar area is created.

The terminal determination unit 304 determines one mobile terminal 100 or one fixed terminal 150 among the mobile terminal 100 and the fixed terminal 150 extracted here. When trying to determine one terminal from a mixture of the mobile terminal 100 and the fixed terminal 150, it is preferable to determine one fixed terminal 150. The fixed terminal 150 may be determined from the device ID, or the device type information may be separately transmitted from the mobile terminal 100 and the fixed terminal 150 and determined based on the device type. .. Further, when trying to determine one terminal from only a plurality of mobile terminals 100, the mobile terminal 100 having the longest estimated remaining operating time (or the largest remaining battery level) is determined based on the estimated remaining operating time. Is good.

The notification unit 305 notifies a terminal other than the mobile terminal 100 or the fixed terminal 150 determined by the terminal determination unit 304 of an instruction signal to stop scanning. In addition, instead of stopping the scan, an instruction signal for lengthening the scan interval or a scan interval longer than the scan interval set immediately before in each mobile terminal 100 is calculated, and the calculated scan interval is notified. It may be. In the calculation method, the scan interval can be lengthened or shortened by adding or subtracting a predetermined numerical value to the scan interval determined by default.

Next, the function of the mobile terminal 100 will be described. FIG. 6 is a block diagram showing the functions of the mobile terminal 100. As shown in FIG. 6, the mobile terminal 100 includes a wireless communication unit 101, a short-range wireless communication unit 102, and a communication control unit 103. The mobile terminal 100 is also composed of hardware as shown in FIG. In the present embodiment, the mobile terminal 100 is, for example, a mobile phone or a smartphone.

The wireless communication unit 101 is a part that communicates with the service server 300 or the management server (not shown) via a network, and transmits scan information.

The short-range wireless communication unit 102 is a portion that scans and detects a wireless tag at predetermined scan intervals. For example, Bluetooth communication can scan the advertisement signal transmitted from the wireless tag.

The communication control unit 103 is a part that controls communication between the wireless communication unit 101 and the short-range wireless communication unit 102. Here, the communication control unit 103 controls the scan interval of the short-range wireless communication unit 102.

The processing of the mobile terminal 100 and the service server 300 configured in this way will be described. FIG. 7 is a sequence diagram showing basic processing between the mobile terminal 100 and the service server 300. Here, as the mobile terminal 100, the mobile terminal a and the mobile terminal b will be described separately.

The wireless tag 200 periodically outputs an advertisement signal including the tag ID (S101). When the mobile terminal a scans and detects this, scan information including the tag ID, the device ID, the scan date and time, and the estimated remaining operating time is transmitted (S102).

Then, in the service server 300, the scan information is stored in the terminal information storage unit 302 (S103), and the similar area determination unit 303 determines whether or not there is a similar area (S104). In the example of FIG. 7, since the scan information comes only from the mobile terminal a, it is determined that there is no similar area.

After that, an advertisement signal is output from the same wireless tag 200, scanned by the mobile terminal b, and detected (S105). Then, the scan information is transmitted to the service server 300 (S106).

In the service server 300, the transmitted scan information is stored in the terminal information storage unit 302 (S107), and the similar area determination unit 303 determines the similar area (S108). Here, since it is the same as the tag ID transmitted from the mobile terminal a, it is determined that there is a similar area. Then, the mobile terminal 100 to be stopped by scanning is determined based on the estimated remaining operation time (S109). Here, it is determined that the estimated remaining operating time of the mobile terminal a is shorter than that of the mobile terminal b, and the service server 300 transmits a scan stop notification including the scan stop time to the mobile terminal a (S110).

When the scan stop notification is received from the service server 300 on the mobile terminal a, the scan is stopped for the scan stop time (S111). Here, you may give an instruction to lengthen the scan interval.

In this way, when the similar area is determined and a plurality of mobile terminals 100 can be extracted, a process of lengthening the scan interval of other mobile terminals 100 other than the determined mobile terminal 100 is performed. Thereby, the battery consumption of the other mobile terminal 100 can be reduced.

Next, more detailed processing of the service server 300 and the mobile terminal 100 of the present embodiment will be described. FIG. 8 is a flowchart showing the processing of the mobile terminal 100 and the service server 300.

In the mobile terminal 100, scanning is performed at predetermined scanning intervals (S201). Then, when one or more wireless tags 200 are detected, the tag list, the scan date and time, and the estimated remaining operation time, which are a list of the tag IDs, are transmitted to the service server 300 together with the device ID (S203).

In the service server 300, the tag list, the scan date and time, and the estimated remaining operation time are received from the mobile terminal 100 (S301), and the similar area determination unit 303 determines whether or not there are a plurality of mobile terminals 100 having similar tag lists. (S302). Here, when there are a plurality of mobile terminals 100 that can be determined to be similar areas, such as when all the tag lists match (S303: YES), the terminal determination unit 304 determines the remaining operating time of the plurality of mobile terminals 100. The longest one is determined, and the other mobile terminal 100 is selected (S303). Then, an instruction to stop scanning indicating a certain period of time is transmitted to the selected mobile terminal 100 (S304).

When the instruction to stop the scan is received in the mobile terminal 100 (S204), the scan is stopped for the scan stop time (S205). Then, when the scan stop time elapses (S206), the scan is performed again, and these processes are repeated. In S304, the service server 300 sends an instruction to stop scanning for a certain period of time, but instead, only an instruction to stop scanning is transmitted, and the mobile terminal 100 side gives an instruction to stop scanning. When it is received, it may be stopped for a scan stop time set in advance on the mobile terminal 100 side.

Next, a process for resetting the similar area in a state where the similar area has already been formed will be described. FIG. 9 is a flowchart of the mobile terminal 100 and the service server 300 that perform the processing.

The mobile terminal 100 performs a scan process, and scan information such as a tag list is transmitted to the service server 300 (S201-S203).

Then, when the service server 300 receives scan information such as a tag list from the mobile terminal 100 (S301), the similar area determination unit 303 determines whether or not the mobile terminal 100 has already formed a similar area. Judgment (S301a).

Here, if it is determined that the similar area is not being formed (S301a: NO), the extraction process of the plurality of mobile terminals forming the similar area and the selection process of the mobile terminal 100 for lengthening the scan interval are performed (S302, S303). Then, the selected mobile terminal 100 is notified (including a new scan interval time) to extend the scan interval (S304a). As described above, the stretching treatment of the scan interval is performed by adding a predetermined value, but other methods may be used. In S304a, the service server 300 transmits an extension instruction including the scan interval time, but instead, only the scan interval extension instruction is transmitted, and the mobile terminal 100 side scans. When the instruction for extending the interval is received, scanning may be performed at a scanning interval set in advance on the mobile terminal 100 side.

When the mobile terminal 100 receives the instruction to extend the scan interval (S204a), the scan process is performed at the extended scan interval (S205a).

Further, when the service server 300 determines in step S301a that a similar area is being formed (S301a: YES), whether or not the tag ID in the received tag list has changed from the previously received tag list. Is determined by the similar area determination unit 303 (S305). Here, if it is determined that they are not the same (S305: NO), the notification unit 305 notifies all the mobile terminals 100 forming this similar area that the scan interval is set to the default. (S306). When a similar area is formed by three or more mobile terminals 100, it is not necessary to reset the similar area other than the detected tag ID changed mobile terminal 100, and the mobile terminal 100 whose tag ID has changed. You may want to set it as the default for only.

When the mobile terminal 100 receives the default setting instruction (S207: YES), a process of returning the scan interval to the default is performed (S208).

Next, the operation and effect of the service server 300 of the present embodiment will be described. In the service server 300, the similar area determination unit 303 forms a plurality of mobile phones that form the same or similar scan area based on the tag ID received by the reception unit 301 and stored in the terminal information storage unit 302. Select terminal 100 or fixed terminal 150. Then, the terminal determination unit 304 controls to suppress the scanning frequency of at least one mobile terminal 100 or the fixed terminal 150 among the plurality of selected mobile terminals 100 or the fixed terminal 150. For example, the scan interval is made longer than the previous scan interval, or the scan is stopped for a predetermined time.

When a plurality of mobile terminals 100 or fixed terminals 150 form the same or similar scan area, the same wireless tag 200 is scanned. Among the plurality of mobile terminals 100 or fixed terminals 150, the scanning frequency of some of the mobile terminals 100 or fixed terminals 150 is suppressed, for example, even if the scanning interval is lengthened or the scanning is stopped for a predetermined time, other mobile phones are used. Unless the scan interval of the terminal 100 or the fixed terminal 150 is changed, the scan accuracy of the entire system is not changed. Therefore, the battery consumption of the other mobile terminal 100 can be reduced without changing the scanning accuracy of the system as a whole.

Further, in the service server 300 of the present embodiment, the terminal determination unit 304 controls to lengthen the scan interval of the mobile terminal 100 that has no margin in the resources determined based on the received resource information, so that the mobile terminal 100 Battery consumption can be reduced. For example, if the remaining battery power is smaller than that of other mobile terminals, it is significant to reduce the battery consumption of the mobile terminal 100. In addition, the CPU operating rate may be higher than that of other mobile terminals, or the free memory capacity may be smaller than that of other mobile terminals.

Further, in the service server 300, when the similar area determination unit 303 determines that the mobile terminal 100 or the fixed terminal 150 has already formed a similar area based on the received device ID, the mobile terminal further further. It is determined whether or not the tag ID received from the 100 or the fixed terminal 150 is the same as the tag ID received at the time of forming the similar area.

Then, when the similar area determination unit 303 determines that they are not the same, the notification unit 305 returns the scan interval of the mobile terminal 100 or the fixed terminal 150 forming the similar area to the initial value. To do. As a result, if the wireless tag 200 is different from the one scanned last time, such as when the wireless tag 200 moves out of the similar area while the similar area is already formed, it may be changed including the mobile terminal 100. In such a case, the scan interval is restored to enable proper scan processing.
