  However, by appropriately assigning communication opportunities to a plurality of wireless communication terminals, appropriate communication may be hindered. For example, in the conventional technology that assigns communication opportunities fairly to a plurality of wireless communication terminals, communication is performed according to the uniformly assigned communication opportunities, so it is difficult to prioritize communication with high priority. .

  Therefore, an object of the present invention is to provide a radio base station apparatus that can flexibly give a communication opportunity to each of a plurality of radio communication terminals.

  The radio base station apparatus according to an aspect of the present invention wirelessly communicates with each of the plurality of radio communication terminals according to the communication opportunity, an assignment unit that allocates a communication opportunity at a predetermined ratio to each of the plurality of radio communication terminals. A communication unit that performs the communication, and when the predetermined communication is performed, the allocation unit changes a ratio of the communication opportunity allocated to each of the plurality of wireless communication terminals from the predetermined ratio.

  Thereby, the radio base station apparatus changes the ratio of communication opportunities allocated to each of the plurality of radio communication terminals from the predetermined ratio when predetermined communication (for example, communication with high priority) is performed. Can do. Therefore, the radio base station apparatus can flexibly give a communication opportunity to each of the plurality of radio communication terminals.

  For example, the predetermined ratio may be an equal ratio in the plurality of wireless communication terminals.

  Thereby, the radio base station apparatus can change the ratio of communication opportunities from an equal ratio when predetermined communication is performed. Therefore, the radio base station apparatus can flexibly give a communication opportunity to each of the plurality of radio communication terminals.

  In addition, for example, the allocating unit changes the ratio of the communication opportunity when the predetermined communication is performed, so that the wireless communication terminal that performs the predetermined communication among the plurality of wireless communication terminals The communication opportunity for performing predetermined communication may be assigned.

  Thereby, the radio base station apparatus can assign a communication opportunity to a predetermined radio communication terminal so that the predetermined radio communication terminal can perform predetermined communication.

  Further, for example, the allocating unit may further return the communication opportunity ratio to the predetermined ratio after the predetermined communication is performed.

  Thereby, the radio base station apparatus can change the ratio of the communication opportunity when the predetermined communication is performed, and can restore the ratio of the communication opportunity after the predetermined communication is performed. That is, the radio base station apparatus can temporarily change the ratio of communication opportunities when predetermined communication is performed.

  Further, for example, the radio base station apparatus further includes a detection unit that detects that the predetermined communication is performed, and the allocation unit is configured to perform the predetermined communication according to a detection result that the predetermined communication is performed. When communication is performed, the communication opportunity ratio may be changed from the predetermined ratio.

  Thereby, the radio base station apparatus can detect that predetermined communication is performed and can change the ratio of communication opportunities.

  In addition, for example, the detection unit receives the predetermined wireless communication when a predetermined wireless communication terminal is notified from the predetermined wireless communication terminal to the wireless base station device. It may be detected that the predetermined communication is performed according to the notification made from the communication terminal.

  Thereby, the radio base station apparatus can detect that predetermined communication is performed according to the notification performed from the radio communication terminal.

  In addition, for example, the detection unit may detect the predetermined wireless communication terminal when data content of communication performed by the predetermined wireless communication terminal among the plurality of wireless communication terminals corresponds to the data content of the predetermined communication. It may be detected that the predetermined communication is performed according to the data content of the communication performed by.

  Thereby, the radio base station apparatus can detect that predetermined communication is performed according to the data content of communication performed by the radio communication terminal.

  In addition, for example, the detection unit further detects that the predetermined communication is not performed, and the allocation unit further determines that the communication opportunity ratio is changed from the predetermined ratio. The ratio of the communication opportunities may be returned to the predetermined ratio according to a detection result that predetermined communication is not performed.

  Thereby, the radio base station apparatus can detect that predetermined communication is not performed, and can restore the ratio of communication opportunities.

  In addition, for example, the detection unit receives the notification that the predetermined communication is not performed from a predetermined wireless communication terminal of the plurality of wireless communication terminals to the wireless base station device. It may be detected that the predetermined communication is not performed according to the notification made from the wireless communication terminal.

  Thereby, the radio base station apparatus can detect that predetermined communication is not performed according to the notification made from the radio communication terminal.

  In addition, for example, the detection unit may detect the predetermined wireless communication terminal when the data content of communication performed by the predetermined wireless communication terminal among the plurality of wireless communication terminals does not correspond to the data content of the predetermined communication. It may be detected that the predetermined communication is not performed according to the data content of the communication performed by.

  Thereby, the radio base station apparatus can detect that predetermined communication is not performed according to the data content of communication performed by the radio communication terminal.

  Further, for example, when the predetermined communication is performed by a wireless communication terminal registered in advance among the plurality of wireless communication terminals, the allocating unit changes the communication opportunity ratio from the predetermined ratio, When the predetermined communication is performed by a wireless communication terminal different from the pre-registered wireless communication terminals among the plurality of wireless communication terminals, the communication opportunity ratio may be maintained at the predetermined ratio. .

  Thereby, the radio base station apparatus can change the ratio of communication opportunities when predetermined communication is performed by a pre-registered radio communication terminal. That is, the radio base station apparatus can limit the radio communication terminals that influence the rate of communication opportunities to pre-registered radio communication terminals.

  For example, the pre-registered wireless communication terminal may be a teacher wireless communication terminal, and the wireless communication terminal different from the pre-registered wireless communication terminal may be a student wireless communication terminal. .

  Accordingly, the radio base station apparatus can change the ratio of communication opportunities when predetermined communication is performed by the teacher radio communication terminal. The radio base station apparatus can maintain the communication opportunity ratio when predetermined communication is performed by the student radio communication terminal. That is, the radio base station apparatus can limit the radio communication terminals that affect the rate of communication opportunities to teacher radio communication terminals.

  Further, for example, the predetermined communication may be communication determined as communication having a higher priority than communication different from the predetermined communication.

  Thereby, the radio base station apparatus can change the ratio of communication opportunities from a predetermined ratio when high priority communication is performed.

  The communication control method according to an aspect of the present invention is a communication control method in a radio base station, wherein a communication opportunity is allocated to each of a plurality of radio communication terminals at a predetermined rate, and the plurality of the communication opportunities according to the communication opportunity. When wireless communication is performed with each of the wireless communication terminals and predetermined communication is performed, the ratio of the communication opportunity assigned to each of the plurality of wireless communication terminals is changed from the predetermined ratio.

  Thereby, the apparatus etc. which perform this communication control method can change the ratio of the communication opportunity allocated with respect to each of a some radio | wireless communication terminal from a predetermined ratio, when predetermined communication is performed. Therefore, a device or the like that executes this communication control method can flexibly give a communication opportunity to each of a plurality of wireless communication terminals.

(Embodiment)
FIG. 1 is a schematic diagram illustrating a configuration example of a communication system 150 including a radio base station apparatus 100 according to the present embodiment. The communication system 150 includes the radio base station apparatus 100 and a plurality of radio communication terminals. The radio base station apparatus 100 is connected to the communication network 102 via a wired communication line 101. The communication network 102 is the Internet, for example.

  The radio base station apparatus 100 is an apparatus that performs radio communication with each of a plurality of radio communication terminals. The radio base station apparatus 100 performs wired communication with another communication apparatus 103 via the communication line 101 and the communication network 102. The wireless base station device 100 is also called a wireless LAN access point or a wireless LAN router. The radio base station apparatus 100 may relay communication between a plurality of radio communication terminals, or between another communication apparatus 103 connected to the communication network 102 and any one of the plurality of radio communication terminals. May be relayed.

  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. In this example, the radio base station apparatus 100 is installed in the classroom 104. Radio base station apparatus 100 performs radio communication with each of a plurality of radio communication terminals in classroom 104. The radio base station apparatus 100 performs wired communication with another communication apparatus 103 outside the classroom 104.

  Each of the plurality of wireless communication terminals is a device that performs wireless communication with the wireless base station device 100. Each of the plurality of wireless communication terminals may communicate with other wireless communication terminals via the wireless base station device 100, or may be connected to the communication network via the wireless base station device 100, the communication line 101, and the communication network 102. You may communicate with the other communication apparatus 103 connected to 102. FIG. Each of the plurality of wireless communication terminals is, for example, a tablet terminal. Each of the plurality of wireless communication terminals may be a portable personal computer or the like.

  In this example, the plurality of wireless communication terminals in the classroom 104 include a teacher wireless communication terminal and a student wireless communication terminal. The teacher wireless communication terminal is operated by the teacher, and the student wireless communication terminal is operated by the student. In addition, a large display 105 is connected to the teacher wireless communication terminal, and the teacher wireless communication terminal can display information to be shown to the student on the display 105.

  The radio base station apparatus 100 allocates a communication opportunity to each of a plurality of radio communication terminals at a predetermined rate. The communication opportunity may be defined by communication time (that is, air time) or may be defined by communication data amount. The predetermined ratio corresponds to the initial ratio, and specifically is an equal ratio in a plurality of wireless communication terminals. That is, the radio base station apparatus 100 assigns to each of the plurality of radio communication terminals a communication opportunity equivalent to the communication opportunity assigned to the other radio communication terminal.

  For example, the radio base station apparatus 100 performs radio communication sequentially with a plurality of radio communication terminals at the same time. At that time, the radio base station apparatus 100 may sequentially perform radio communication with a plurality of radio communication terminals such that the length of communication time is equal among the plurality of radio communication terminals. Specifically, the radio base station apparatus 100 delays the start of the next communication as the one communication time is longer for each radio communication terminal, and the next communication as the one communication time is shorter. May start earlier. Thereby, a communication opportunity is equally allocated in a some radio | wireless communication terminal.

  Alternatively, the radio base station apparatus 100 may sequentially perform radio communication with a plurality of radio communication terminals so that the communication data amount is equal among the plurality of radio communication terminals. Specifically, for each wireless communication terminal, the radio base station apparatus 100 delays the start of the next communication as the amount of one communication data is larger, and the smaller the amount of one communication data is, The start of communication may be accelerated. Thereby, a communication opportunity is equally allocated in a some radio | wireless communication terminal.

  Alternatively, the radio base station apparatus 100 may allocate communication opportunities evenly in a plurality of radio communication terminals by adjusting the time of communication performed continuously or the amount of data of communication performed continuously. .

  The radio base station apparatus 100 can suppress monopolization of communication opportunities by one radio communication terminal by allocating communication opportunities equally among a plurality of radio communication terminals. Thereby, the radio base station apparatus 100 can give a communication opportunity to each of the plurality of radio communication terminals according to fairness in the plurality of radio communication terminals.

  However, for example, a teacher's wireless communication terminal may perform video streaming playback via the communication network 102 and the like, and display the video on the display 105 in order to show the video to the student. Even in such a case, since communication opportunities are evenly allocated in a plurality of wireless communication terminals, there is a possibility that sufficient communication opportunities are not given to the teacher wireless communication terminal and streaming playback is not performed appropriately. is there. As a result, the video may not be displayed properly.

  The radio base station apparatus 100 changes the ratio of communication opportunities when predetermined communication is performed in order to suppress adverse effects caused by equal allocation of communication opportunities. For example, the wireless base station device 100 increases the ratio of the communication opportunity for the teacher wireless communication terminal when the communication for streaming playback is performed as the predetermined communication by the teacher wireless communication terminal, Reduce the rate of communication opportunities for wireless communication terminals.

  At this time, the radio base station apparatus 100 may shorten the interval of communication performed a plurality of times with respect to the teacher radio communication terminal, or may increase the time of communication performed continuously. However, the data amount of communication performed continuously may be increased. The radio base station apparatus 100 may increase the interval of communication performed over a plurality of times with respect to the student radio communication terminal, or may shorten the time of communication performed continuously. The data amount of communication performed continuously may be reduced.

  Thereby, the radio base station apparatus 100 can give a sufficient communication opportunity to the teacher radio communication terminal when communication for streaming reproduction is performed by the teacher radio communication terminal. As a result, streaming playback is appropriately performed and video is appropriately displayed.

  FIG. 2 is a block diagram showing a configuration example of the radio base station apparatus 100 shown in FIG. The radio base station apparatus 100 includes a registration unit 111, a detection unit 112, an allocation unit 113, and a communication unit 114.

  For example, each of these components is an electric circuit. These components may be implemented by a processor, a memory, and the like. That is, the radio base station apparatus 100 may include a processor and a memory, and may operate as the registration unit 111, the detection unit 112, the allocation unit 113, and the communication unit 114 when the processor performs information processing.

  The registration unit 111 is an electric circuit that registers a wireless communication terminal. For example, the registration unit 111 registers a teacher wireless communication terminal. The registration unit 111 may register the wireless communication terminal by storing information indicating the wireless communication terminal in a memory. The information indicating the wireless communication terminal may be the MAC address of the wireless communication terminal, the IP address of the wireless communication terminal, or another identifier of the wireless communication terminal.

  For example, when predetermined communication is performed by the wireless communication terminals registered by the registration unit 111, the ratio of communication opportunities assigned to each of the plurality of wireless communication terminals is changed from an equal ratio. And when predetermined | prescribed communication is performed by the radio | wireless communication terminal which is not registered by the registration part 111, the ratio of the communication opportunity allocated with respect to each of several radio | wireless communication terminals is maintained at an equal ratio.

  For example, the registration unit 111 may receive information indicating a teacher wireless communication terminal from the teacher wireless communication terminal via the communication unit 114. Then, the registration unit 111 may register the teacher wireless communication terminal by storing the received information in the memory as information indicating the teacher wireless communication terminal.

  The detection unit 112 is an electric circuit that detects that predetermined communication is performed. The predetermined communication may be communication for streaming reproduction. For example, when the wireless communication terminal for teachers notifies the wireless base station device 100 that predetermined communication is performed, the detection unit 112 detects that predetermined communication is performed based on the notification. Alternatively, the detection unit 112 detects that the predetermined communication is performed based on the data content of the communication when the data content of the communication performed by the teacher wireless communication terminal corresponds to the data content of the predetermined communication. .

  Moreover, the detection part 112 may detect that predetermined | prescribed communication is not performed. For example, when the wireless communication terminal for teachers notifies the wireless base station device 100 that the predetermined communication is not performed, the detection unit 112 detects that the predetermined communication is not performed based on the notification. Alternatively, the detection unit 112 detects that the predetermined communication is not performed based on the data content of the communication when the data content of the communication performed by the teacher wireless communication terminal does not correspond to the data content of the predetermined communication. To do.

  The assigning unit 113 is an electric circuit that assigns communication opportunities to each of a plurality of wireless communication terminals at a predetermined rate. Specifically, the assigning unit 113 assigns communication opportunities equally to each of the plurality of wireless communication terminals.

  Then, the allocation unit 113 changes the ratio of communication opportunities from an equal ratio when predetermined communication is performed. For example, the assigning unit 113 assigns a communication opportunity for performing predetermined communication to a wireless communication terminal performing predetermined communication by changing the ratio of communication opportunities from an equal ratio. That is, the allocating unit 113 secures a communication opportunity for performing predetermined communication with a wireless communication terminal that performs predetermined communication by changing the ratio of communication opportunities from an equal ratio.

  Specifically, the assignment unit 113 may assign communication opportunities to wireless communication terminals that perform predetermined communication at a rate determined as a rate for performing predetermined communication.

  Further, the assignment unit 113 changes the ratio of communication opportunities from an equal ratio when predetermined communication is performed by the teacher wireless communication terminal, and when predetermined communication is performed by the student wireless communication terminal. The communication opportunity ratio may be maintained at an equal ratio. For example, when predetermined communication is performed by a registered wireless communication terminal, the ratio of communication opportunities is changed from an equal ratio, and when predetermined communication is performed by an unregistered wireless communication terminal, The ratio may be maintained at an equal ratio.

  For example, the allocating unit 113 returns the ratio of communication opportunities to an equal ratio after predetermined communication is performed. That is, the assigning unit 113 assigns communication opportunities equally to each of the plurality of wireless communication terminals after predetermined communication is performed.

  The communication unit 114 is an electric circuit that performs wireless communication with each of a plurality of wireless communication terminals. The communication unit 114 performs wired communication with other communication devices 103.

  The communication unit 114 performs wireless communication with each of the plurality of wireless communication terminals according to the communication opportunity. As the communication opportunity assigned to the wireless communication terminal increases, the communication unit 114 can use a longer communication time or a larger communication data amount for communication with the wireless communication terminal.

  FIG. 3 is an image diagram illustrating an implementation example of the radio base station apparatus 100 illustrated in FIG. 1 and the like. For example, the radio base station apparatus 100 includes an antenna 121, a connection terminal 122, a processor 123, and a memory 124. The registration unit 111, the detection unit 112, and the allocation unit 113 are configured by a processor 123 and a memory 124. The communication unit 114 includes an antenna 121, a connection terminal 122, a processor 123, and a memory 124.

  That is, the processor 123 and the memory 124 operate as the registration unit 111, the detection unit 112, and the allocation unit 113. The antenna 121, the connection terminal 122, the processor 123, and the memory 124 operate as the communication unit 114.

  The antenna 121 is an antenna for wireless communication. Information transmitted or received by wireless communication is transmitted or received by radio waves by the antenna 121. The connection terminal 122 is a connection terminal for wired communication, to which the communication line 101 is connected. Information transmitted or received by wired communication is transmitted or received via the connection terminal 122 and the communication line 101.

  The processor 123 is a processor that performs information processing. For example, the processor 123 performs information processing for the antenna 121, the connection terminal 122, the processor 123, and a part or all of the memory 124 to operate as the registration unit 111, the detection unit 112, the allocation unit 113, and the communication unit 114. Do.

  The processor 123 may be a general-purpose processor or a dedicated processor. For example, when the processor 123 is a general-purpose processor, the processor 123 performs the above-described information processing by reading a program from the memory 124 and executing the program.

  The memory 124 is a memory for storing information. The memory 124 may store data for the processor 123 to perform information processing, or may store a program for the processor 123 to perform information processing. The memory 124 may store information indicating registered wireless communication terminals. The memory 124 may include a volatile memory, may include a nonvolatile memory, may include a ROM, or may include a RAM.

  The radio base station apparatus 100 may include a plurality of antennas, a plurality of connection terminals, a plurality of processors, and a plurality of memories. The radio base station apparatus 100 may include a different processor and memory for each of the registration unit 111, the detection unit 112, the allocation unit 113, and the communication unit 114.

  FIG. 4 is a schematic diagram illustrating an example of communication opportunities equally allocated by the radio base station apparatus 100 illustrated in FIG. 1 and the like. In FIG. 4, the thickness of the arrow corresponds to the amount of communication opportunities. For example, the radio base station apparatus 100 allocates a communication opportunity to each of a plurality of radio communication terminals including a teacher radio communication terminal and a student radio communication terminal. In a normal case, the radio base station apparatus 100 allocates communication opportunities equally among a plurality of radio communication terminals.

  For example, when radio communication is performed between the radio base station apparatus 100 and each of 10 radio communication terminals in the same period, the radio base station apparatus 100 performs communication with each of the 10 radio communication terminals. A communication opportunity corresponding to 1/10 of the entire communication opportunity is assigned. The radio base station apparatus 100 does not give a communication opportunity to a radio communication terminal that does not perform radio communication, but gives a communication opportunity to a radio communication terminal that performs radio communication, thereby performing a radio communication terminal. Can provide greater communication opportunities.

  FIG. 5 is a schematic diagram illustrating an example of communication opportunities assigned at a rate changed by the radio base station apparatus 100 illustrated in FIG. 1 and the like. In FIG. 5, the thickness of the arrow corresponds to the amount of communication opportunities. For example, when predetermined communication is performed by a teacher's wireless communication terminal, the wireless base station device 100 changes the ratio of communication opportunities from an equal ratio. Specifically, in this case, the radio base station apparatus 100 increases the ratio of communication opportunities allocated to the teacher radio communication terminals, and increases the ratio of communication opportunities allocated to the student radio communication terminals. Reduce the ratio.

  For example, when communication for streaming playback is performed by a teacher wireless communication terminal, the radio base station apparatus 100 changes the ratio of communication opportunities so that communication for streaming playback is appropriately performed. The radio base station apparatus 100 may assign a communication opportunity corresponding to the communication time or communication data amount required for the communication for streaming reproduction to the teacher wireless communication terminal by changing the ratio of the communication opportunity. .

  Then, the radio base station apparatus 100 gives the remaining communication opportunities to the plurality of student radio communication terminals by removing the communication opportunities assigned to the teacher radio communication terminals from the overall communication opportunities. For example, the radio base station apparatus 100 has the remaining communication opportunities for each of the nine radio communication terminals for students among the ten radio communication terminals that perform radio communication with the radio base station apparatus 100 at the same time. A communication opportunity corresponding to 1/9 of is assigned.

  Thereby, the radio base station apparatus 100 changes the ratio of communication opportunities assigned to each of the plurality of radio communication terminals from an equal ratio.

  Further, for example, the radio base station apparatus 100 allocates a communication opportunity four times the equal ratio to the teacher radio communication terminals, and an equal ratio is allocated to each of the nine radio communication terminals for students. A 2/3 communication opportunity may be assigned. In this case, a communication opportunity corresponding to 2/5 of the entire communication opportunity is allocated to the teacher's wireless communication terminal, and a communication opportunity corresponding to 1/15 of the entire communication opportunity is nine wireless for students. Assigned to each of the communication terminals.

  Note that the ratio of communication opportunities may not be defined as an absolute value. For example, the proportion of communication opportunities may be relatively defined, such as the proportion of communication opportunities that are assigned to teacher wireless communication terminals more than student wireless communication terminals.

  FIG. 6 is a flowchart showing an operation example of the radio base station apparatus 100 shown in FIG. For example, each component shown in FIG. 2 operates according to the operation example of FIG.

  Specifically, first, the registration unit 111 registers a wireless communication terminal (S101). For example, the registration unit 111 receives information indicating the teacher wireless communication terminal from the teacher wireless communication terminal via the communication unit 114 and stores the information indicating the teacher wireless communication terminal in the memory 124. Thus, a teacher wireless communication terminal may be registered.

  Next, the assigning unit 113 assigns communication opportunities to each of the plurality of wireless communication terminals at an equal rate (S102). Next, the communication unit 114 performs wireless communication with a plurality of wireless communication terminals according to the communication opportunity (S103).

  Thereafter, the assigning unit 113 determines whether or not predetermined communication is performed in the registered wireless communication terminal (S104). For example, when the detection unit 112 detects that predetermined communication is performed at the registered wireless communication terminal, and the allocation unit 113 performs predetermined communication at the registered wireless communication terminal based on the detection result. You may judge. Alternatively, the detection unit 112 detects that predetermined communication is not performed at the registered wireless communication terminal, and the allocation unit 113 performs predetermined communication at the registered wireless communication terminal based on the detection result. It may be determined that there is not.

  When predetermined communication is performed with the registered wireless communication terminal (Yes in S104), the assigning unit 113 changes the communication opportunity ratio from the equal ratio and assigns the communication opportunity at the changed ratio (S105). ). On the other hand, when predetermined communication is not performed in the registered wireless communication terminal (No in S104), the assigning unit 113 maintains or returns the ratio of communication opportunities to an equal ratio, and allocates communication opportunities at an equal ratio ( S106).

  Then, the assigning unit 113 and the communication unit 114 repeat communication processing and the like (S103 to S106).

  Thereby, the radio base station apparatus 100 can change the ratio of communication opportunities from an equal ratio when predetermined communication is performed. And the radio | wireless base station apparatus 100 can return the ratio of a communication opportunity to an equal ratio after predetermined | prescribed communication is performed.

  FIG. 7 is a schematic diagram illustrating an operation example in which the radio base station apparatus 100 illustrated in FIG. 1 and the like registers a radio communication terminal.

  In this example, a registration screen, which is a GUI for registering a teacher wireless communication terminal, is displayed on the touch panel of the teacher wireless communication terminal. Such a registration screen may be displayed by an application program transmitted from the wireless base station device 100 to the teacher wireless communication terminal. For security reasons, such a registration screen may be displayed when a predetermined password is input.

  In this example, the MAC address of the teacher's wireless communication terminal is displayed. The display may be an IP address. A registration button for registering a teacher wireless communication terminal is displayed. When the registration button is pressed, the MAC address of the teacher's wireless communication terminal is transmitted to the wireless base station device 100 (the above MAC address or IP address may be input by the user). The registration unit 111 acquires the MAC address of the teacher wireless communication terminal via the communication unit 114, and stores the MAC address of the teacher wireless communication terminal in the memory 124. sign up.

  Thereby, the radio base station apparatus 100 can register a radio communication terminal. Then, the radio base station apparatus 100 controls whether or not to change the communication opportunity ratio from an equal ratio according to whether or not a wireless communication terminal that performs predetermined communication is a registered wireless communication terminal. Can do.

  Note that this example is an example of an operation in which the radio base station device 100 registers a radio communication terminal, and the operation in which the radio base station device 100 registers a radio communication terminal is not limited to this example. Information indicating the wireless communication terminal for teacher is transmitted from a device different from the wireless communication terminal for teacher to the wireless base station device 100, and the registration unit 111 of the wireless base station device 100 acquires the transmitted information, A teacher wireless communication terminal may be registered.

  Alternatively, the radio base station apparatus 100 includes a user interface, and the registration unit 111 of the radio base station apparatus 100 acquires information indicating the teacher radio communication terminal via the user interface and registers the teacher radio communication terminal. May be.

  FIG. 8 is a schematic diagram illustrating an operation example in which the radio base station apparatus 100 illustrated in FIG. 1 and the like detects predetermined communication according to the notification.

  In this example, a setting screen that is a GUI for setting the streaming mode on or off is displayed on the touch panel of the teacher's wireless communication terminal. Such a setting screen may be displayed by an application program transmitted from the wireless base station device 100 to the teacher wireless communication terminal. For security reasons, such a setting screen may be displayed when a predetermined password is input.

Moreover, the radio base station apparatus 100 can detect that predetermined communication is not performed according to the data content of communication, and can maintain the ratio of communication opportunities at an equal ratio. Alternatively, the radio base station apparatus 100 can detect that predetermined communication is not performed according to the data content of communication, and can return the ratio of communication opportunities to an equal ratio.

  As in the above embodiment, the radio base station apparatus 100 assigns communication opportunities equally to each of the plurality of radio communication terminals. And the radio base station apparatus 100 communicates with each of a some radio | wireless communication terminal by radio | wireless according to the communication opportunity allocated equally. In addition, when predetermined communication is performed, the radio base station apparatus 100 changes the rate of communication opportunities, and performs radio communication with each of the plurality of radio communication terminals according to the communication opportunities assigned at the changed rate. .
