Description

  The present invention relates to a radio base station apparatus that performs radio communication.

  Conventionally, techniques for restricting wireless communication in a wireless communication environment have been proposed. The techniques described in Patent Document 1 and Patent Document 2 are examples of such a technique.

  For example, in the technique described in Patent Document 1, the communication connection management device stores terminal identification information, a maximum usable time, and an elapsed connection time in association with each other using a user ID as a key. Then, the communication connection management device sets an available time corresponding to a usage fee such as a food and drink paid by the user, and permits the client terminal to access the Internet. The communication connection management device notifies the user's terminal when the remaining time is short, and prompts the user to perform a service extension procedure.

  Thereby, access to the Internet from a client terminal in a wireless LAN free spot such as a restaurant is limited to a use time preset for each user.

  In the technique described in Patent Document 2, a relay device serving as a wireless LAN access point pays attention to a packet indicating a communication start request among packets to be relayed between terminal devices, and a terminal included in the packet Record device identification information. When the number of terminal devices that have recorded the identification information exceeds a preset upper limit value, the relay device disconnects communication related to the latest recorded identification information by transmitting a disconnect command or discarding the packet.

  As a result, the relay device disconnects communication exceeding the upper limit value regarding the number of communication. Therefore, the relay device can protect the number of communications suitable for streaming communication. Thereby, the relay device can prevent the quality deterioration of the streaming communication.

  However, it is not easy for the radio base station apparatus to perform radio communication exclusively with one radio communication terminal suitable as a communication partner.

  For example, in a place where a plurality of unspecified people gather, it may not be appropriate in terms of security for a plurality of wireless communication terminals possessed by a plurality of people to perform wireless communication with a wireless base station device at the same time. In order to avoid a plurality of wireless communication terminals performing wireless communication with the wireless base station apparatus at the same time, the number of wireless communication terminals that can be connected to the wireless base station apparatus may be limited to one. However, other wireless communication terminals can automatically connect to the wireless base station apparatus, and a problem that a wireless communication terminal that should perform wireless communication cannot connect to the wireless base station apparatus may occur.

  In addition, it is assumed that the radio base station apparatus receives the input of identification information or the like of the radio communication terminal that should perform radio communication and performs radio communication exclusively with the radio communication terminal. However, input of identification information and the like involves complicated operations, and the complicated operations impede smooth wireless communication.

  Therefore, an object of the present invention is to provide a radio base station apparatus capable of performing radio communication exclusively with one radio communication terminal suitable as a communication partner.

  A radio base station apparatus according to an aspect of the present invention is a radio base station apparatus that performs radio communication, a communication interface unit that transmits and receives radio signals, and a communication that controls radio communication performed via the communication interface unit A control unit, wherein the communication control unit is connected between the radio base station apparatus and the radio communication terminal until a predetermined connection period elapses after the radio base station apparatus and the radio communication terminal are connected by radio. When a communication request that is a request for wireless communication and is a request transmitted from the wireless communication terminal according to an operation on the wireless communication terminal is received by the wireless base station device, the wireless base station device and the wireless communication terminal The communication request is permitted until the predetermined connection period elapses after the wireless communication is permitted and the wireless base station device and the wireless communication terminal are wirelessly connected. If not received by the device, the wireless base station device and the wireless communication terminal are disconnected, and the wireless base station device and the wireless communication terminal are allowed to communicate with the wireless base station while wireless communication is permitted. The wireless connection between the station device and another wireless communication terminal is prohibited.

  Thereby, the radio base station apparatus can exclusively perform radio communication with one radio communication terminal suitable as a communication partner. Therefore, the radio base station apparatus can improve security related to radio communication.

  For example, the communication control unit disconnects a wireless connection between the wireless base station device and the other wireless communication terminal when the wireless base station device and the other wireless communication terminal are wirelessly connected. And rejecting a new wireless connection between the wireless base station device and the other wireless communication terminal when the wireless base station device and the other wireless communication terminal are not wirelessly connected, Wireless connection between the wireless base station device and the other wireless communication terminal may be prohibited.

  Thereby, the radio base station apparatus can appropriately eliminate unnecessary radio connections, and can appropriately perform exclusive radio communication.

  In addition, for example, the communication control unit is configured such that the wireless base station device is in a period from when the wireless base station device and the wireless communication terminal are wirelessly connected until the communication request is received by the wireless base station device. And wireless communication between the wireless base station device and the other wireless communication terminal, and when the communication request is received by the wireless base station device and wireless communication between the wireless base station device and the wireless communication terminal is permitted, Prohibition of wireless connection between the wireless base station device and the other wireless communication terminal may be started.

  Thereby, the radio base station apparatus can permit radio connection between the radio base station apparatus and the plurality of radio communication terminals until a communication request is received. Therefore, the radio base station apparatus can appropriately receive a communication request from any one of a plurality of radio communication terminals.

  Also, for example, the communication control unit starts prohibiting wireless connection between the wireless base station device and the other wireless communication terminal when the wireless base station device and the wireless communication terminal are wirelessly connected. May be.

  Thereby, the radio base station apparatus can exclusively perform radio connection and can appropriately perform exclusive radio communication. In addition, since unnecessary wireless connections that do not perform wireless communication are disconnected after the lapse of a predetermined connection period, the wireless communication terminal that is to perform wireless communication cannot be connected to the wireless base station device by other exclusive wireless connection. It is suppressed.

  In addition, for example, the communication control unit may further perform radio communication between the radio base station apparatus and the radio communication terminal when the communication request is not received by the radio base station apparatus before the predetermined connection period elapses. After the connection is disconnected, a new wireless connection between the wireless base station device and the wireless communication terminal may be rejected.

  Thereby, the radio base station apparatus can suppress the radio base station apparatus and a radio communication terminal not having a communication schedule from being wirelessly connected again. Therefore, the radio base station apparatus can appropriately eliminate unnecessary radio connections.

  In addition, for example, the radio base station apparatus further includes an operation interface unit that receives an operation on the radio base station apparatus, and the communication control unit has a predetermined validity period after the operation on the radio base station apparatus is received. Until the elapse of time, the wireless base station apparatus and the wireless communication terminal are enabled to start a wireless connection start process, and after the predetermined validity period has elapsed, the wireless base station apparatus and the wireless communication terminal start wireless connection. Processing may be disabled.

  As a result, the radio base station apparatus can limit the period in which the radio connection between the radio base station apparatus and the radio communication terminal starts, and suppress unnecessary radio connection between the radio base station apparatus and the radio communication terminal. Can do.

  Further, for example, the communication control unit causes the radio base station apparatus and the radio communication terminal to transmit at least one of a beacon and a probe response from the radio base station apparatus until the predetermined effective period elapses. The wireless connection start process of the wireless base station apparatus and the wireless communication terminal are not transmitted after the predetermined validity period has elapsed, by not transmitting a beacon and a probe response from the wireless base station apparatus. The start process may be invalidated.

  Thereby, the radio base station apparatus can appropriately prohibit the start of the radio connection between the radio base station apparatus and the radio communication terminal after the predetermined effective period has elapsed.

  In addition, for example, the communication control unit may perform wireless communication between the wireless base station device and the wireless communication terminal after a predetermined communication period has elapsed since wireless communication between the wireless base station device and the wireless communication terminal has been permitted. When disconnecting and disconnecting the wireless connection between the wireless base station device and the wireless communication terminal, the wireless base station device and the wireless communication terminal are released from the wireless communication permission, and the wireless base station device The prohibition of wireless connection with the other wireless communication terminal may be lifted.

  Thereby, the radio base station apparatus can suppress that the radio communication terminal continues to dedicate the radio base station apparatus.

  A radio communication system according to an aspect of the present invention includes the radio base station apparatus and the radio communication terminal, and the radio communication terminal transmits the communication request according to an operation on the radio communication terminal. By executing this, the communication request is transmitted in accordance with an operation on the wireless communication terminal.

  Thereby, the radio | wireless communications system can transmit a communication request | requirement from a radio | wireless communication terminal appropriately according to operation with respect to a radio | wireless communication terminal, and can receive a communication request | requirement appropriately in a radio base station apparatus.

  In addition, the communication control method according to one aspect of the present invention provides a communication between the wireless base station device and the wireless communication terminal until a predetermined connection period elapses after the wireless base station device and the wireless communication terminal are wirelessly connected. When a communication request that is a request for wireless communication and is a request transmitted from the wireless communication terminal according to an operation on the wireless communication terminal is received by the wireless base station device, the wireless base station device and the wireless communication terminal When wireless communication is permitted and the communication request is not received by the wireless base station device after the predetermined connection period has elapsed since the wireless base station device and the wireless communication terminal are wirelessly connected, While the wireless connection between the wireless base station device and the wireless communication terminal is disconnected and wireless communication between the wireless base station device and the wireless communication terminal is permitted, the wireless base station device and another Prohibiting a wireless connection between the line communication terminal.

(Embodiment)
FIG. 1 is an image diagram showing an implementation example of a wireless communication system 400 according to the present embodiment. The wireless communication system 400 includes the wireless base station device 100, the wireless communication terminal 201, and the like. The radio base station apparatus 100 is connected to a file server 301, a printer 302, and the like via a wired communication line 303. The wireless communication system 400 may be connected to a communication network such as the Internet via a wired communication line 303.

  The wireless base station device 100 is a device that performs wireless communication, and is also called a wireless LAN access point or a wireless LAN router. The radio base station apparatus 100 performs radio communication with one radio communication terminal among a plurality of radio communication terminals 201 and 202 and the like at the same time. Then, the radio base station apparatus 100 performs radio communication with another radio communication terminal at another time. That is, the radio base station apparatus 100 restricts radio communication so that only one radio communication terminal among the plurality of radio communication terminals 201 and 202 performs radio communication at the same time.

  The radio base station apparatus 100 performs wired communication with a plurality of other apparatuses including the file server 301 and the printer 302 via the communication line 303. The wireless base station device 100 may perform wired communication with a plurality of other devices at the same time, together with wireless communication with one wireless communication terminal. For example, the radio base station apparatus 100 relays communication between the radio communication terminal 201 and the printer 302.

  Wireless communication is performed using, for example, a wireless LAN that conforms to the IEEE802.11a, b, g, or n standards. Wired communication is performed using, for example, a wired LAN conforming to the IEEE 802.3 standard.

  Each of the wireless communication terminals 201 and 202 is a device that performs wireless communication with the wireless base station device 100. Each of the wireless communication terminals 201 and 202 may communicate with the file server 301 or the printer 302 via the wireless base station device 100 and the communication line 303. Each of the wireless communication terminals 201 and 202 may be a smartphone, a tablet terminal, a portable personal computer, a mobile phone, or the like.

  For example, the wireless communication system 400 is constructed in a place where a plurality of unspecified people gather. If the wireless communication terminals 201 and 202 can communicate with the printer 302 at the same time, the printed material output by the instruction of the wireless communication terminal 201 and the printed material output by the instruction of the wireless communication terminal 202 are mixed. There is a possibility to fit. If these printed materials have contents that require confidentiality, it is not appropriate from the viewpoint of security to separate them visually.

  Also, if the wireless communication terminals 201 and 202 can communicate with the file server 301 at the same time, the processing load on the wireless base station device 100 and the file server 301 may increase. Then, the radio base station apparatus 100 or the file server 301 may stop due to overload.

  Therefore, as described above, the radio base station apparatus 100 restricts radio communication so that only one radio communication terminal among the plurality of radio communication terminals 201 and 202 performs radio communication at the same time. Thereby, the radio base station apparatus 100 can restrict radio communication so that the radio communication terminals 201 and 202 do not communicate with the file server 301 or the printer 302 at the same time.

  On the other hand, when the radio base station apparatus 100 can be connected to only one of the plurality of radio communication terminals 201 and 202, the radio base station apparatus 100 performs radio communication among the plurality of radio communication terminals 201 and 202, etc. This may cause a problem that it is not possible to connect to the wireless communication terminal that should perform the communication. For example, since the radio base station apparatus 100 is automatically connected to another radio communication terminal 202 that does not have a plan to perform radio communication, the radio communication terminal that originally has a plan to perform radio communication 201 may not be connected.

  Further, for example, the radio base station apparatus 100 communicates with a radio communication terminal that is to perform radio communication via input of identification information or the like of the radio communication terminal that is to perform radio communication among the plurality of radio communication terminals 201 and 202. The wireless communication may be performed by connecting with. However, input of identification information and the like involves complicated operations, and the complicated operations impede smooth wireless communication.

  Therefore, for example, when the wireless base station device 100 receives a communication request from the wireless communication terminal 201 after the wireless connection with the wireless communication terminal 201 until the predetermined connection period elapses, Wireless connection with the wireless communication terminal 202 or the like is prohibited. In this case, the radio base station apparatus 100 permits radio communication between the radio base station apparatus 100 and the radio communication terminal 201. For example, only in this case, the radio base station apparatus 100 may perform radio communication processing and perform radio communication with the radio communication terminal 201.

  In addition, when the wireless base station device 100 does not receive a communication request from the wireless communication terminal 201 before the predetermined connection period elapses after wirelessly connecting to the wireless communication terminal 201, the wireless base station device 100 wirelessly communicates with the wireless base station device 100. The wireless connection with the communication terminal 201 is disconnected.

  The communication request is a request for wireless communication. In a state where the wireless base station device 100 and the wireless communication terminal 201 are connected wirelessly, an operation on the wireless communication terminal 201 causes a wireless base station device to operate. 100. The operation on the wireless communication terminal 201 is, for example, an operation for selecting an object using a GUI, and may be a simple operation different from a complicated operation such as character input.

  In the above operation, the radio base station apparatus 100 is connected to the radio communication terminal 201 by radio, but the operation when the radio base station apparatus 100 is connected to the radio communication terminal 202 by radio is the same. That is, in the above description, the wireless communication terminal 201 and the wireless communication terminal 202 may be interchanged.

  In an environment including three or more wireless communication terminals, a wireless communication terminal different from the two wireless communication terminals 201 and 202 may be handled in the same manner as the other wireless communication terminals 202. For example, when receiving a communication request from the wireless communication terminal 201, the wireless base station device 100 prohibits wireless connection between the wireless base station device 100 and a wireless communication terminal different from the two wireless communication terminals 201 and 202. .

  Through the above operation, the radio base station apparatus 100 can perform radio communication exclusively with one radio communication terminal suitable as a communication partner. Therefore, the radio base station apparatus 100 can improve security regarding radio communication. Moreover, since the radio base station apparatus 100 eliminates unnecessary radio connections, the processing load can be reduced.

The communication control unit 112 prohibits wireless connection with another wireless communication terminal at least while wireless communication with a certain wireless communication terminal is permitted. If the communication control unit 112 does not receive a communication request from the wireless communication terminal before the predetermined connection period elapses after the start of the wireless connection with the certain wireless communication terminal, the communication control unit 112 disconnects the wireless connection.

  The communication interface unit 113 is an electric circuit that transmits and receives radio signals.

  Thereafter, the wireless communication terminal 201 receives an operation on the wireless communication terminal 201 (S103). Specifically, the operation interface unit 211 of the wireless communication terminal 201 receives an operation on the wireless communication terminal 201.

  Then, the radio communication terminal 201 transmits a communication request to the radio base station apparatus 100 in accordance with an operation on the radio communication terminal 201 (S104). Specifically, the communication control unit 212 of the wireless communication terminal 201 transmits a communication request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 to the wireless base station device 100 in accordance with an operation on the wireless communication terminal 201. .

  In this example, the radio base station apparatus 100 receives a communication request until a predetermined connection period elapses after the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. That is, the communication control unit 112 of the radio base station apparatus 100 communicates via the communication interface unit 113 until a predetermined connection period elapses after the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. Receive a request. The predetermined connection period is, for example, 1 minute, but may be arbitrarily defined.

  In response to the communication request, the radio base station apparatus 100 permits radio communication between the radio base station apparatus 100 and the radio communication terminal 201, and transmits a communication permission to the radio communication terminal 201 (S105). For example, the communication control unit 112 of the wireless base station device 100 enables wireless communication processing, and wirelessly permits wireless communication between the wireless base station device 100 and the wireless communication terminal 201 via the communication interface unit 113. Transmit to the communication terminal 201.

  Thereby, wireless communication between the wireless base station device 100 and the wireless communication terminal 201 becomes possible. On the contrary, wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is not possible until a communication request is received. That is, the radio base station apparatus 100 does not relay communication before receiving a communication request, but relays communication after transmitting a communication permission. The radio base station apparatus 100 prohibits wireless connection between the radio base station apparatus 100 and another radio communication terminal 202 after receiving the communication request.

  In this example, after a communication request is received by the radio base station apparatus 100 from the radio communication terminal 201, another radio communication terminal 202 transmits a connection request for radio connection between the radio base station apparatus 100 and the radio communication terminal 202. (S106). In response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 202 (S107). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits, to the radio communication terminal 202, a connection rejection of the radio connection between the radio base station apparatus 100 and the radio communication terminal 202 via the communication interface unit 113. .

  That is, when the communication control unit 112 of the radio base station apparatus 100 receives a communication request from the radio communication terminal 201 via the communication interface unit 113, the communication control unit 112 establishes a radio connection between the radio base station apparatus 100 and another radio communication terminal 202. Ban. Thereby, exclusive wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is more reliably performed. Also, unnecessary wireless connections are eliminated.

  In the above description, the wireless communication terminal 201 and the wireless communication terminal 202 may be interchanged. In the above description, the operations of the two wireless communication terminals 201 and 202 are shown for convenience of explanation, but three or more wireless communication terminals may be used. For example, a new wireless communication terminal different from the two wireless communication terminals 201 and 202 can be handled in the same manner as the wireless communication terminal 202. The same applies to the description of the subsequent operation examples.

  FIG. 7 is a sequence diagram showing a second operation example of the wireless communication system 400 shown in FIG. In this example, a communication request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is not received until the predetermined connection period elapses, and the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is established. Disconnected.

  Specifically, first, the radio communication terminal 201 transmits a connection request to the radio base station apparatus 100 (S201). In response to the connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 201 (S202). Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. These processes (S201, S202) are the same as the processes (S101, S102) in the example of FIG.

  In this example, the wireless base station device 100 does not receive a communication request until a predetermined connection period elapses after the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected. In this case, the radio base station apparatus 100 disconnects the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 (S203). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits a signal for disconnecting the radio connection to the radio communication terminal 201 via the communication interface unit 113 to disconnect the radio connection.

  Further, in this example, after the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected, another wireless communication terminal 202 issues a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202. Transmit (S204).

  In response to this connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 202 (S205). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits connection permission for radio connection between the radio base station apparatus 100 and the radio communication terminal 202 to the radio communication terminal 202 via the communication interface unit 113. . Thereby, the radio base station apparatus 100 and the radio communication terminal 202 are connected by radio.

  Thereafter, the wireless communication terminal 202 receives an operation on the wireless communication terminal 202 (S206). Then, the wireless communication terminal 202 transmits a communication request to the wireless base station device 100 in accordance with an operation on the wireless communication terminal 202 (S207). In this example, the radio base station apparatus 100 receives a communication request until a predetermined connection period elapses after the radio base station apparatus 100 and the radio communication terminal 202 are connected by radio.

  Then, in response to the communication request, the radio base station device 100 permits radio communication between the radio base station device 100 and the radio communication terminal 202, and transmits a communication permission to the radio communication terminal 202 (S208). For example, the communication control unit 112 of the radio base station apparatus 100 validates the radio communication process, and permits the radio communication communication permission between the radio base station apparatus 100 and the radio communication terminal 202 via the communication interface unit 113. Transmit to terminal 202. Thereby, wireless communication between the wireless base station device 100 and the wireless communication terminal 202 becomes possible.

  In the above operation, since the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected after the predetermined connection period has elapsed, unnecessary wireless connections are eliminated. Therefore, the processing load in the radio base station apparatus 100 is suppressed. Thereafter, the wireless base station device 100 and the wireless communication terminal 202 can perform wireless communication by connecting wirelessly.

  FIG. 8 is a sequence diagram showing a third operation example of the radio communication system 400 shown in FIG. In this example, wireless connection between the wireless base station device 100 and another wireless communication terminal 202 is permitted until a communication request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is received.

  Specifically, first, the wireless communication terminal 201 transmits a connection request to the wireless base station device 100 (S301). In response to the connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 201 (S302). Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. These processes (S301, S302) are the same as the processes (S101, S102) in the example of FIG.

  In this example, next, another wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202 (S303). At this time, the radio base station apparatus 100 has not received a communication request. Therefore, in response to this connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 202 (S304). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits connection permission for radio connection between the radio base station apparatus 100 and the radio communication terminal 202 to the radio communication terminal 202 via the communication interface unit 113. .

  Thereby, the radio base station apparatus 100 and the radio communication terminal 202 are connected by radio. That is, a plurality of radio communication terminals 201 and 202 are connected to the radio base station apparatus 100.

  Thereafter, the wireless communication terminal 201 receives an operation on the wireless communication terminal 201 (S305). Then, the wireless communication terminal 201 transmits a communication request to the wireless base station device 100 in accordance with an operation on the wireless communication terminal 201 (S306). In response to the communication request, the radio base station apparatus 100 transmits a communication permission to the radio communication terminal 201 (S307). These processes (S305 to S307) are the same as the processes (S103 to S105) in the example of FIG.

  Further, the radio base station apparatus 100 disconnects the radio connection between the radio base station apparatus 100 and the radio communication terminal 202 (S308). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits a signal for disconnecting the radio connection to the radio communication terminal 202 via the communication interface unit 113 to disconnect the radio connection. This disconnection process may be performed before transmission of the communication permission.

  Thereafter, the other wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202 (S309). In response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 202 (S310). These processes (S309, S310) are the same as the processes (S106, S107) in the example of FIG.

  In the above operation, another wireless connection is permitted until a communication request for wireless communication is received. That is, other wireless connections are not prohibited until a communication request for wireless communication is received. Thereby, the radio base station apparatus 100 can permit radio connection between the radio base station apparatus 100 and each of the plurality of radio communication terminals 201 and 202. Therefore, the radio base station apparatus can appropriately receive a communication request from any one of the plurality of radio communication terminals 201 and 202.

  FIG. 9 is a sequence diagram illustrating a fourth operation example of the wireless communication system 400 illustrated in FIG. In this example, prohibition of wireless connection between the wireless base station device 100 and another wireless communication terminal 202 is started when the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected.

  Specifically, first, the radio communication terminal 201 transmits a connection request to the radio base station apparatus 100 (S401). In response to the connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 201 (S402). Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. These processes (S401, S402) are the same as the processes (S101, S102) in the example of FIG.

  In this example, the communication control unit 112 of the wireless base station device 100 prohibits wireless connection between the wireless base station device 100 and another wireless communication terminal 202 when the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected. To start.

  After that, another wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202 (S403). Therefore, in response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 202 (S404). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits, to the radio communication terminal 202, a connection rejection of the radio connection between the radio base station apparatus 100 and the radio communication terminal 202 via the communication interface unit 113. .

  Therefore, the radio base station apparatus 100 and the radio communication terminal 202 are not connected by radio. That is, only the radio communication terminal 201 among the plurality of radio communication terminals 201 and 202 is connected to the radio base station apparatus 100.

  Thereafter, the wireless communication terminal 201 receives an operation on the wireless communication terminal 201 (S405). Then, the wireless communication terminal 201 transmits a communication request to the wireless base station device 100 in accordance with an operation on the wireless communication terminal 201 (S406). Then, in response to the communication request, the radio base station apparatus 100 transmits a communication permission to the radio communication terminal 201 (S407). These processes (S405 to S407) are the same as the processes (S103 to S105) in the example of FIG.

  Further, thereafter, the other wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202 (S408). In response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 202 (S409). These processes (S408, S409) are the same as the processes (S106, S107) in the example of FIG.

  In the above operation, prohibition of other wireless connections is started at the time of wireless connection. Thereby, the radio base station apparatus 100 can perform radio connection exclusively, and can appropriately perform exclusive radio communication. Note that unnecessary wireless connections in which wireless communication is not performed are disconnected after a predetermined connection period has elapsed, and thus adverse effects caused by exclusive wireless connections are suppressed.

  FIG. 10 is a sequence diagram illustrating a fifth operation example of the wireless communication system 400 illustrated in FIG. In this example, a communication request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is not received until the predetermined connection period elapses, and the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is established. Disconnected. Furthermore, a new wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is rejected.

  Specifically, first, the wireless communication terminal 201 transmits a connection request to the wireless base station device 100 (S501). In response to the connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 201 (S502). Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio. Thereafter, until the predetermined connection period elapses, the wireless base station device 100 does not receive a communication request, and the wireless base station device 100 disconnects the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 (S503). ).

  The above processing (S501 to S503) is the same as the processing (S201 to S203) in the example of FIG. In this example, after that, the communication control unit 112 of the radio base station apparatus 100 rejects a new radio connection between the radio base station apparatus 100 and the radio communication terminal 201 by filtering.

  For example, the communication control unit 112 of the radio base station apparatus 100 holds the information of the radio communication terminal 201 when the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 is disconnected without receiving a communication request. . The information of the wireless communication terminal 201 may be the MAC address of the wireless communication terminal 201. Then, for example, when receiving a connection request from the wireless communication terminal 201 having the same MAC address, the communication control unit 112 transmits a connection rejection as a response.

  Specifically, in this example, after the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected, the wireless communication terminal 201 makes a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 201. Is transmitted (S504).

  In response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 201 (S505). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits to the radio communication terminal 201 a connection refusal of radio connection between the radio base station apparatus 100 and the radio communication terminal 201 via the communication interface unit 113. .

  In the above operation, if the wireless communication terminal 201 does not transmit a communication request, then wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is prohibited. Thereby, it is suppressed that the radio base station apparatus 100 and the radio communication terminal 201 not scheduled to perform radio communication are automatically connected by radio. Therefore, unnecessary wireless connections are eliminated, and the processing load on the radio base station apparatus 100 is suppressed. For example, the wireless base station device 100 and the other wireless communication terminal 202 can be smoothly connected wirelessly.

  FIG. 11 is a sequence diagram showing a sixth operation example of the radio communication system 400 shown in FIG. In this example, the radio base station apparatus 100 validates the wireless connection start process according to an operation on the radio base station apparatus 100.

  For example, the radio base station apparatus 100 does not transmit a beacon and a probe response when no operation is performed on the radio base station apparatus 100. That is, the communication control unit 112 of the radio base station device 100 does not transmit the beacon and the probe response from the communication interface unit 113 of the radio base station device 100 when the operation on the radio base station device 100 is not performed.

  Specifically, in this example, the wireless communication terminal 201 transmits a probe request (S601, S602). That is, the communication control unit 212 of the wireless communication terminal 201 transmits a probe request via the communication interface unit 213. In response to this probe request, the radio base station apparatus 100 does not transmit a probe response. That is, the communication control unit 112 of the radio base station apparatus 100 does not transmit a probe response from the communication interface unit 113 of the radio base station apparatus 100.

  Thereafter, the radio base station apparatus 100 receives an operation on the radio base station apparatus 100 (S603). Specifically, the operation interface unit 111 of the radio base station apparatus 100 receives an operation on the radio communication terminal 201. Then, after receiving the operation for the radio base station apparatus 100, the radio base station apparatus 100 transmits a beacon (S604). For example, the communication control unit 112 of the radio base station apparatus 100 transmits a beacon via the communication interface unit 113. The operation on the radio base station apparatus 100 includes, for example, that the user of the radio communication terminal 201 or an administrator of the system receiving the user's request presses an operation button provided on the radio base station apparatus 100. It is done.

  Then, the wireless communication terminal 201 transmits a probe request (S605). Specifically, the communication control unit 212 of the wireless communication terminal 201 transmits a probe request via the communication interface unit 213. In response to this probe request, the radio base station apparatus 100 transmits a probe response to the radio communication terminal 201 (S606). For example, the communication control unit 112 of the radio base station apparatus 100 transmits a probe response to the radio communication terminal 201 via the communication interface unit 113 of the radio base station apparatus 100.

  Then, the radio communication terminal 201 transmits an authentication request to the radio base station apparatus 100 (S607). Specifically, the communication control unit 212 of the wireless communication terminal 201 transmits an authentication request to the wireless base station device 100 via the communication interface unit 213. In response to this authentication request, the radio base station apparatus 100 transmits an authentication response to the radio communication terminal 201 (S608). For example, the communication control unit 112 of the radio base station apparatus 100 transmits an authentication response to the radio communication terminal 201 via the communication interface unit 113 of the radio base station apparatus 100.

  Then, the radio communication terminal 201 transmits an association request to the radio base station apparatus 100 (S609). Specifically, the communication control unit 212 of the wireless communication terminal 201 transmits an association request to the wireless base station device 100 via the communication interface unit 213.

  In response to this association request, the radio base station apparatus 100 transmits an association response to the radio communication terminal 201 (S610). For example, the communication control unit 112 of the radio base station apparatus 100 transmits an association response to the radio communication terminal 201 via the communication interface unit 113 of the radio base station apparatus 100.

  The association request may correspond to a connection request. Further, the association response may correspond to a connection permission or connection rejection response. For example, the wireless communication terminal 201 transmits an association request corresponding to a connection request to the wireless base station device 100, and the wireless base station device 100 transmits an association response corresponding to connection permission to the wireless communication terminal 201. Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio.

  Note that the connection request may include a probe request, an authentication request, and an association request, and the connection permission or connection rejection response may include a probe response, an authentication response, and an association response.

  In addition, the request and response in the above description may be omitted. Specifically, when beacon transmission / reception is performed, transmission / reception of probe requests and probe responses may be omitted. Further, when probe requests and probe responses are transmitted and received, beacon transmission and reception may be omitted. Also, the authentication request and the authentication response may be omitted.

  In the above operation, after the operation on the radio base station apparatus 100 is performed, the wireless connection start process becomes valid. This limits the start of wireless connection and eliminates unnecessary wireless connection. Therefore, the processing load in the radio base station apparatus 100 is suppressed. Further, an appropriate wireless connection is established by operating the wireless base station device 100 when using wireless communication.

  FIG. 12 is a sequence diagram showing a seventh operation example of the wireless communication system 400 shown in FIG. In this example, the radio base station apparatus 100 validates the wireless connection start process according to an operation on the radio base station apparatus 100, as in the example of FIG. In this example, the radio base station apparatus 100 further invalidates the wireless connection start process after a predetermined valid period has elapsed.

  For example, the radio base station apparatus 100 does not transmit a beacon and a probe response before an operation on the radio base station apparatus 100 and after a predetermined effective period has elapsed since the operation on the radio base station apparatus 100. That is, the communication control unit 112 of the radio base station device 100 transmits a beacon and a probe response from the communication interface unit 113 of the radio base station device 100 before the operation on the radio base station device 100 and after a predetermined effective period has elapsed since the operation. Will not be sent.

  Specifically, the wireless communication terminal 201 transmits a probe request (S701, S702). In response to this probe request, the radio base station apparatus 100 does not transmit a probe response. Thereafter, the radio base station apparatus 100 receives an operation on the radio base station apparatus 100 (S703). These processes (S701 to S703) are the same as the processes (S601 to S603) in the example of FIG.

  The radio base station apparatus 100 transmits a beacon after receiving an operation on the radio base station apparatus 100 (S704, S705). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits a beacon via the communication interface unit 113. Thereafter, in this example, a probe request, an authentication request, and an association request are not received by the radio base station apparatus 100 from the radio communication terminal 201, and the predetermined effective period has elapsed.

  For example, the automatic connection of the wireless communication terminal 201 may be invalid, or the wireless communication terminal 201 may not exist within the communicable range. In such a case, the probe request, authentication request, and association request are not received by the radio base station apparatus 100 from the radio communication terminal 201. The radio base station apparatus 100 stops beacon transmission after the elapse of a predetermined valid period. The predetermined effective period is, for example, 1 minute, but may be arbitrarily defined.

  Thereafter, the wireless communication terminal 201 transmits a probe request (S706, S707). In response to this probe request, the radio base station apparatus 100 does not transmit a probe response. These processes (S706, S707) are the same as the processes (S701, S702) before the operation on the radio base station apparatus 100.

  In the above operation, the wireless connection start process becomes invalid after a predetermined valid period has elapsed since the operation on the radio base station apparatus 100. This limits the start of wireless connection and eliminates unnecessary wireless connection. Therefore, the processing load in the radio base station apparatus 100 is suppressed.

  FIG. 13 is a sequence diagram showing an eighth operation example of the wireless communication system 400 shown in FIG. In this example, the radio base station apparatus 100 allows radio communication between the radio base station apparatus 100 and the radio communication terminal 201 after a predetermined communication period has elapsed since the radio communication between the radio base station apparatus 100 and the radio communication terminal 201 has been permitted. Disconnect the connection.

  Specifically, first, the wireless communication terminal 201 transmits a connection request to the wireless base station device 100 (S801). In response to the connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 201 (S802). Thereby, the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio.

  Thereafter, the wireless communication terminal 201 receives an operation on the wireless communication terminal 201 (S803). Then, the radio communication terminal 201 transmits a communication request to the radio base station apparatus 100 in accordance with an operation on the radio communication terminal 201 (S804). In response to the communication request, the radio base station apparatus 100 permits radio communication between the radio base station apparatus 100 and the radio communication terminal 201, and transmits a communication permission to the radio communication terminal 201 (S805).

  Thereafter, the other wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202 (S806). In response to this connection request, the radio base station apparatus 100 transmits a connection refusal to the radio communication terminal 202 (S807).

  The above processing (S801 to S807) is the same as the processing (S101 to S107) in the example of FIG.

  In this example, the radio base station apparatus 100 performs radio communication between the radio base station apparatus 100 and the radio communication terminal 201 after elapse of a predetermined communication period after the radio communication between the radio base station apparatus 100 and the radio communication terminal 201 is permitted. The connection is disconnected (S808). Specifically, the communication control unit 112 of the radio base station apparatus 100 transmits a signal for disconnecting the radio connection to the radio communication terminal 201 via the communication interface unit 113 when a predetermined communication period has elapsed, Disconnect the connection. The predetermined connection period is, for example, 5 minutes, but may be arbitrarily defined.

  If the wireless base station device 100 and the wireless communication terminal 201 are in the middle of wireless communication when the predetermined communication period has elapsed, the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected after the wireless communication. May be. The predetermined communication period may be extended by some method based on the state of wireless communication. For example, the radio base station apparatus 100 receives an extension request from the user of the radio communication terminal.

  Further, the communication control unit 112 of the radio base station apparatus 100 permits the radio communication between the radio base station apparatus 100 and the radio communication terminal 201 when the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 is disconnected. Is released. The communication control unit 112 of the radio base station apparatus 100 may invalidate the radio communication process related to data relay. In addition, the communication control unit 112 of the radio base station apparatus 100 performs radio connection between the radio base station apparatus 100 and another radio communication terminal 202 when the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 is disconnected. Remove the prohibition.

  In this example, after the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected, another wireless communication terminal 202 transmits a connection request for wireless connection between the wireless base station device 100 and the wireless communication terminal 202. (S809). In response to this connection request, the radio base station apparatus 100 transmits a connection permission to the radio communication terminal 202 (S810). Thereby, the radio base station apparatus 100 and the radio communication terminal 202 are connected by radio.

  Thereafter, the wireless communication terminal 202 receives an operation on the wireless communication terminal 202 (S811). Then, the radio communication terminal 202 transmits a communication request to the radio base station apparatus 100 in accordance with an operation on the radio communication terminal 202 (S812). In response to the communication request, the radio base station apparatus 100 permits radio communication between the radio base station apparatus 100 and the radio communication terminal 202, and transmits a communication permission to the radio communication terminal 202 (S813). Thereby, wireless communication between the wireless base station device 100 and the wireless communication terminal 202 becomes possible.

  The above processing (S809 to S813) is the same as the processing (S204 to S208) in the example of FIG.

  In the above operation, the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected after a predetermined communication period has elapsed. Then, along with the disconnection of the radio connection between the radio base station apparatus 100 and the radio communication terminal 201, the permission of radio communication between the radio base station apparatus 100 and the radio communication terminal 201 is released, and the radio base station apparatus 100 and other The prohibition of wireless connection with the wireless communication terminal 202 is lifted. Therefore, the radio base station apparatus 100 can suppress the radio communication terminal 201 from continuing to dedicate the radio base station apparatus 100.

  FIG. 14 is a flowchart showing an operation example of the radio base station apparatus 100 shown in FIG.

  First, the communication control unit 112 determines whether or not the current time is within a predetermined valid period after the operation interface unit 111 receives an operation on the radio base station apparatus 100 (S901). If the current time is not within the predetermined valid period (No in S901), the communication control unit 112 invalidates the wireless connection start process (S903). On the other hand, when the current time is within the predetermined valid period (Yes in S901), the communication control unit 112 validates the wireless connection start process (S902).

  When the wireless connection start process is valid, the wireless connection is performed. For example, the radio base station apparatus 100 is wirelessly connected to the radio communication terminal 201 (S904). If the communication control unit 112 does not receive a communication request before the predetermined connection period elapses from the wireless connection (No in S905), the communication control unit 112 disconnects the wireless connection (S912) and prohibits reconnection (S913). .

  Further, when the communication control unit 112 receives a communication request before the predetermined connection period elapses from the wireless connection (Yes in S905), the communication control unit 112 permits the wireless communication (S906) and prohibits the other wireless connection (S907). . Thereby, the radio base station apparatus 100 performs radio communication (S908). For example, the radio base station apparatus 100 communicates with the radio communication terminal 201 connected to the radio base station apparatus 100 by radio. The radio base station apparatus 100 performs radio communication until a predetermined communication period elapses after the radio communication is permitted (No in S909).

  When the predetermined communication period has elapsed since the wireless communication was permitted (Yes in S909), the communication control unit 112 disconnects the wireless connection (S910). For example, when the radio base station apparatus 100 and the radio communication terminal 201 are connected wirelessly, the communication control unit 112 disconnects the radio connection between the radio base station apparatus 100 and the radio communication terminal 201. The communication control unit 112 cancels the permission of wireless communication and cancels the prohibition of other wireless connections as the wireless connection is disconnected.

  The wireless base station device 100 repeats the above operation to wirelessly connect to one wireless communication terminal suitable as a communication partner from a plurality of wireless communication terminals 201, 202, etc. It can communicate with the terminal wirelessly.

  FIG. 15 is an image diagram showing a display example of a GUI for operating the wireless communication terminal 201 shown in FIG. Here, the GUI of the wireless communication terminal 201 is shown, but the GUIs of the other wireless communication terminals 202 are the same.

  For example, the wireless communication terminal 201 displays an icon 231 for performing wireless communication on the touch panel 225. When the icon 231 displayed on the touch panel 225 is touched in a state where the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected, the wireless communication terminal 201 sends a communication request to the wireless base station device. To 100. The radio base station apparatus 100 permits radio communication according to the communication request. Thereby, wireless communication between the wireless base station device 100 and the wireless communication terminal 201 becomes possible.

  A program for transmitting a communication request to the radio base station apparatus 100 in accordance with an operation on the radio communication terminal 201 is preinstalled in the radio communication terminal 201 and executed by the communication control unit 212. For example, this program is a dedicated program for transmitting a communication request according to an operation. The communication control unit 212 can transmit a communication request according to a simple operation by executing a dedicated program.

  Further, for example, a dedicated program for transmitting a communication request according to an operation may be incorporated in the application program for printing. Then, a communication request may be transmitted when printing is performed according to an operation such as pressing a GUI print button displayed by an application program for printing. Such a mechanism can be applied to uses other than printing, for example, file operations.

  Moreover, not only a dedicated program but a general-purpose program may be used for transmission of a communication request. For example, a browser that is a general-purpose program for browsing a Web page may be used. The wireless communication terminal 201 may receive an operation on the wireless communication terminal 201 with a browser, access the wireless base station device 100, and transmit a communication request to the wireless base station device 100.

  Thereby, even if a dedicated program is not installed in the wireless communication terminal 201, the wireless communication terminal 201 can transmit a communication request to the wireless base station device 100.

  Note that the radio base station apparatus 100 may operate as a DHCP (Dynamic Host Configuration Protocol) server. When the wireless base station device 100 receives a communication request from the wireless communication terminal 201, the wireless base station device 100 assigns an IP address or the like to the wireless communication terminal 201, thereby performing wireless communication between the wireless base station device 100 and the wireless communication terminal 201. It may be possible. Thereby, the radio base station apparatus 100 can appropriately permit radio communication between the radio base station apparatus 100 and the radio communication terminal 201.

  In addition, a dedicated communication protocol may be used for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 instead of a general-purpose communication protocol. For example, a unique communication protocol in the upper layer of TCP / IP may be used for wireless communication between the wireless base station device 100 and the wireless communication terminal 201.

  As described above, the radio base station apparatus 100 and the radio communication system 400 according to an aspect of the present invention have been described based on the embodiments and the like.

For example, the radio communication system 400 may include only the radio base station apparatus 100 and the radio communication terminal 201. Other devices may or may not be included in other systems. For example, the radio base station apparatus 100 may include only the communication control unit 112 and the communication interface unit 113. The operation interface unit 111 may not exist.

That is, each step is executed by the processor obtaining data from a memory or the like and performing an operation, or outputting the operation result to a memory or the like.

  In addition, a plurality of components included in the radio base station apparatus 100 or the like may be realized as dedicated or general-purpose circuits, respectively. These components may be realized as a single circuit or may be realized as a plurality of circuits.

May be performed.

  Hereinafter, basic configurations, modifications, effects, and the like of the radio base station device 100 and the like according to an aspect of the present invention are described.

  (1) The radio base station apparatus 100 according to an aspect of the present invention is a radio base station apparatus that performs radio communication, and includes a communication interface unit 113 and a communication control unit 112. The communication interface unit 113 transmits and receives wireless signals. The communication control unit 112 controls wireless communication performed via the communication interface unit 113.

  Then, when the communication request is received by the radio base station apparatus 100 after the predetermined connection period elapses after the radio base station apparatus 100 and the radio communication terminal 201 are connected by radio, the communication control unit 112 Wireless communication between the base station apparatus 100 and the wireless communication terminal 201 is permitted. In addition, the communication control unit 112, when the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected, until the predetermined connection period elapses, the communication request is not received by the wireless base station device 100, The wireless connection between the wireless base station device 100 and the wireless communication terminal 201 is disconnected.

  Here, the communication request is a request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 and is a request transmitted from the wireless communication terminal 201 in accordance with an operation on the wireless communication terminal 201. The communication control unit 112 prohibits wireless connection between the wireless base station device 100 and another wireless communication terminal 202 while wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is permitted.

  Thereby, the radio base station apparatus 100 can perform radio communication exclusively with one radio communication terminal suitable as a communication partner. Therefore, the radio base station apparatus 100 can improve security regarding radio communication.

  (2) For example, the communication control unit 112 disconnects and rejects the wireless connection between the wireless base station device 100 and the other wireless communication terminal 202, thereby establishing a wireless connection between the wireless base station device 100 and the other wireless communication terminal 202. It may be prohibited.

  Here, the disconnection of the radio connection between the radio base station apparatus 100 and the other radio communication terminal 202 is performed when the radio base station apparatus 100 and the other radio communication terminal 202 are connected by radio. And disconnecting the wireless connection with the other wireless communication terminal 202. The rejection of the wireless connection between the wireless base station device 100 and the other wireless communication terminal 202 is performed when the wireless base station device 100 and the other wireless communication terminal 202 are not connected wirelessly. This means that a new wireless connection with another wireless communication terminal 202 is rejected.

  Thereby, the radio base station apparatus 100 can appropriately eliminate unnecessary radio connections and can appropriately perform exclusive radio communication.

  (3) For example, the communication control unit 112 waits until the wireless base station device 100 receives a communication request after the wireless base station device 100 and the wireless communication terminal 201 are connected wirelessly. And wireless connection with another wireless communication terminal 202 may be permitted. Then, when the communication request is received by the radio base station apparatus 100 and the radio base station apparatus 100 and the radio communication terminal 201 allow radio communication, the communication control unit 112 and the radio base station apparatus 100 and other radio Prohibition of wireless connection with the communication terminal 202 may be started.

  Thereby, the radio base station apparatus 100 can permit radio connection between the radio base station apparatus 100 and a plurality of radio communication terminals until a communication request is received. Therefore, the radio base station apparatus 100 can appropriately receive a communication request from any one of a plurality of radio communication terminals.

  (4) For example, the communication control unit 112 prohibits wireless connection between the wireless base station device 100 and another wireless communication terminal 202 when the wireless base station device 100 and the wireless communication terminal 201 are wirelessly connected. You may start. Thereby, the radio base station apparatus 100 can perform radio connection exclusively, and can appropriately perform exclusive radio communication. In addition, since unnecessary wireless connections in which wireless communication is not performed are disconnected after the elapse of a predetermined connection period, adverse effects that are hindered by other wireless connections exclusive for wireless communication are suppressed.

  (5) For example, when the communication request is not received before the predetermined connection period elapses, the communication control unit 112 disconnects the wireless connection between the wireless base station device 100 and the wireless communication terminal 201, and then the wireless base station device A new wireless connection between the wireless communication terminal 100 and the wireless communication terminal 201 may be rejected. Thereby, the radio base station apparatus 100 can suppress the unnecessary radio connection with the radio base station apparatus 100 from being repeated. Therefore, the radio base station apparatus 100 can appropriately eliminate unnecessary radio connections.

  (6) For example, the radio base station apparatus 100 may further include an operation interface unit 111 that receives an operation on the radio base station apparatus 100. Then, the communication control unit 112 enables the start processing of the wireless connection between the wireless base station device 100 and the wireless communication terminal 201 until the predetermined effective period elapses after the operation on the wireless base station device 100 is received. Good. Then, the communication control unit 112 may invalidate the wireless connection start process between the radio base station apparatus 100 and the radio communication terminal 201 after a predetermined valid period has elapsed.

  Thereby, the radio base station apparatus 100 can limit the period during which radio connection is started, and can suppress useless radio connection.

  (7) For example, the communication control unit 112 causes the radio base station apparatus 100 and the radio communication terminal 201 to transmit at least one of a beacon and a probe response from the radio base station apparatus 100 until a predetermined effective period elapses. The wireless connection start process may be validated. In addition, the communication control unit 112 performs wireless connection start processing between the wireless base station device 100 and the wireless communication terminal 201 by not transmitting the beacon and the probe response from the wireless base station device 100 after the predetermined effective period has elapsed. It may be disabled.

  Thereby, the radio base station apparatus 100 can appropriately prohibit the start of the radio connection after the elapse of the predetermined effective period.

  (8) For example, after the predetermined communication period has elapsed since the wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is permitted, the communication control unit 112 performs the communication between the wireless base station device 100 and the wireless communication terminal 201. The wireless connection may be disconnected. Then, when disconnecting the wireless connection, the communication control unit 112 cancels permission of wireless communication between the wireless base station device 100 and the wireless communication terminal 201, and wireless communication between the wireless base station device 100 and the other wireless communication terminal 202 is performed. Connection prohibition may be lifted.

  Thereby, the radio base station apparatus 100 can suppress that one radio communication terminal continues to dedicate the radio base station apparatus 100.

  (9) The wireless communication system 400 according to an aspect of the present invention includes the wireless base station device 100 and the wireless communication terminal 201. The wireless communication terminal 201 transmits a communication request according to an operation on the wireless communication terminal 201 by executing a program for transmitting the communication request according to an operation on the wireless communication terminal 201.

  Thereby, the wireless communication system 400 can appropriately transmit a communication request from the wireless communication terminal 201 in accordance with an operation on the wireless communication terminal 201, and the wireless base station apparatus 100 can appropriately receive the communication request.

  (10) In the communication control method according to one aspect of the present invention, when a communication request is received by the radio base station apparatus 100 from the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 until the predetermined connection period has elapsed, Wireless communication between the base station apparatus 100 and the wireless communication terminal 201 is permitted. Here, the communication request is a request for wireless communication between the wireless base station device 100 and the wireless communication terminal 201 and is a request transmitted from the wireless communication terminal 201 in accordance with an operation on the wireless communication terminal 201.

  Also, in this communication control method, when the communication request is not received by the radio base station apparatus 100 before the predetermined connection period elapses, the radio connection between the radio base station apparatus 100 and the radio communication terminal 201 is disconnected. In this communication control method, the wireless connection between the wireless base station device 100 and another wireless communication terminal 202 is prohibited while wireless communication between the wireless base station device 100 and the wireless communication terminal 201 is permitted.
