  An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 1 schematically shows the configuration of a wireless communication system. The wireless communication system 1 includes a base station 2 and a terminal station 3, and is configured to transmit and receive transmission packets between the base station 2 and the terminal station 3. Hereinafter, the case where the base station 2 transmits a transmission packet to the terminal station 3 will be described, but the same applies to the case where the terminal station 3 transmits a transmission packet to the base station 2. The same applies when the base station 2 transmits a transmission packet to another base station 2 or when the terminal station 3 transmits a transmission packet to another terminal station 3.

  FIG. 2 shows the configuration of the base station 2 as a functional block diagram. The base station 2 includes a communication control unit 4, a modem 5, an IF unit 6, and an RF unit 7. The communication control unit 4 includes a channel controller 8 that controls the overall operation of the base station 2, a transmission buffer 9 that temporarily stores transmission packets to be transmitted to the terminal station 3, and temporary received packets received from the terminal station 3. The reception buffer 10 that accumulates automatically, and transmission control units 111 to 11n and reception control units 121 to 12n corresponding to each of a plurality of channels (n (n is a natural number of 2 or more) channels) are configured.

  A transmission packet is input to the transmission buffer 9 from, for example, Ethernet (registered trademark). When a transmission packet is input from the transmission buffer 9 through the channel controller 8, each transmission control unit 111 to 11n performs transmission processing on the input transmission packet and outputs the transmission packet to each modem 51 to 5n. When the transmission packets transmitted from the transmission control units 111 to 11n are input to the modems 51 to 5n, the data strings of the input transmission packets are modulated and output to the IF units 61 to 6n.

  When the signals obtained by modulating the data strings of the transmission packets are input from the modems 51 to 5n, the IF units 61 to 6n up-convert the input signals to a predetermined frequency and output the signals to the RF unit 7. Then, when the up-converted signals are input from the IF units 61 to 6n, the RF unit 7 up-converts the input signals and performs addition processing for a plurality of channels to radiate from the antenna 13 as transmission radio waves. To do.

  In the configuration described above, the channel controller 8 outputs a control signal to each of the transmission control units 111 to 11n, each of the reception control units 121 to 12n, and each of the modems 51 to 5n, so that each of the transmission control units 111 to 11n, The reception control units 121 to 12n and the modems 51 to 5n are controlled. In FIG. 2, the flow of the control signal is indicated by a broken line arrow, and the flow of the transmission packet and the received packet is indicated by a solid line arrow.

Next, the operation of the above configuration will be described with reference to FIGS. here,
(1) Process in which base station 2 transmits each of a plurality of transmission packets to terminal station 3 in parallel on a plurality of channels in packet units (2) Relationship between base station 2 and terminal station 3 between a master station and a slave station For registering and authenticating whether or not multiple channels are established (processing corresponding to claims 1 to 23 in the present invention)
Each will be described in turn.
(1) Process in which base station 2 transmits each of a plurality of transmission packets in parallel in a plurality of channels to terminal station 3 in the unit of packets First, “Base station 2 transmits a plurality of transmission packets in a unit of packets in a plurality of channels The process of transmitting to the terminal station 3 in parallel with reference to FIG. 3 to FIG. FIG. 3 is a flowchart showing processing performed by the channel controller 8 in the base station 2.

  The channel controller 8 periodically monitors whether or not the transmission packet is accumulated in the transmission buffer 9 (step S1), and detects that the transmission packet is accumulated in the transmission buffer 9 (step S1). "YES"), a transmission counter (transmission timer) is started (step S2).

  Next, the channel controller 8 monitors whether or not the number of transmission packets stored in the transmission buffer 9 has reached a predetermined number (step S3), and at the same time, the transmission counter counts up (time up). It is monitored whether or not (step S4). In this case, the specified number corresponds to a number equal to or less than the number on the hardware of the transmission control units 111 to 11n (the modems 51 to 5n and the IF units 61 to 6n), and is described as “n” here. .

  As shown in FIG. 4, the channel controller 8 detects that the number of transmission packets stored in the transmission buffer 9 has reached a predetermined number n before the transmission counter counts up. Then ("YES" in step S3), n transmission packets stored in the transmission buffer 9 at that time are output from the transmission buffer 9 to the transmission control units 111 to 11n, thereby transmitting n transmissions. The packet is transmitted to the terminal station 3 in parallel by n channels (step S5).

Then, the channel controller 8 resets the transmission counter (step S6), returns to step S1, and repeats the above processing.
On the other hand, as shown in FIG. 5, the channel controller 8 counts up the transmission counter before the number of transmission packets stored in the transmission buffer 9 reaches a predetermined number n. When it is detected (“YES” in step S4), n transmission packets less than n (here, (n−1)) in the transmission buffer 9 are stored from the transmission buffer 9 at that time. The less than n transmission packets are output to the terminal station 3 in parallel via the less than n channels by outputting to less than each transmission control unit (step S7).

  Then, the channel controller 8 resets the transmission counter (step S8), returns to step S1, and repeats the above processing. If the number of transmission packets stored in the transmission buffer 9 at the time when the transmission counter is counted up is less than (n−1), the channel controller 8 transmits less than (n−1) transmission packets. To send. 4 and 5, the specified count time of the transmission counter (the time from the start to the count-up) is indicated as “T1”, and the specified count time of the transmission counter depends on, for example, the system configuration The time can be set arbitrarily.

  Through the processing described above, the base station 2 does not divide each of the n transmission packets and transmits the divided packets to the terminal station 3, but in parallel with each of the n transmission packets in n channels in packet units. Transmit to the terminal station 3.

  Incidentally, as shown in FIG. 6, the base station 2 can transmit n transmission packets having the same packet length (data capacity) to the terminal station 3 in parallel through n channels. However, as shown in FIG. 7, it is also possible to transmit n transmission packets having different packet lengths in parallel through n channels to the terminal station 3 (in FIG. 7, the packet length of the transmission packet (2) is Different from others).

  Further, after transmitting the transmission packet to the terminal station 3, the base station 2 monitors whether or not the ACK packet is received from the terminal station 3 within a specified time, as shown in FIGS. When it is detected that the ACK packet has not been received from the station 3 within the specified time, it is also possible to retransmit the transmission packet that was not normally received by the terminal station 3.

  More specifically, the base station 2 starts an ACK packet reception counter immediately after transmitting a transmission packet to the terminal station 3, monitors whether an ACK packet is received from the terminal station 3, and simultaneously receives an ACK packet. Monitors whether the reception counter has counted up. When the base station 2 detects that the ACK packet is received from the terminal station 3 before the ACK packet reception counter is incremented, the base station 2 recognizes that the transmission packet has been normally received by the terminal station 3. To do.

  On the other hand, when the base station 2 detects that the ACK packet reception counter has counted up before the ACK packet is received from the terminal station 3, the transmission packet is not normally received by the terminal station 3. The terminal station 3 retransmits the transmission packet that was not normally received.

  In this case, as shown in FIG. 9, the base station 2 detects that the ACK packet reception counter has counted up and then transmits a predetermined number of transmission packets (in FIG. 9, transmission packets (4) to (6) ) Can be retransmitted after being transmitted to the terminal station 3 (in FIG. 9, the transmission packet (3)), and an ACK packet is received as shown in FIG. Immediately after the counter counts up, it is also possible to retransmit the transmission packet that was not normally received by the terminal station 3 (also the transmission packet (3) in FIG. 10). 9 and 10, the specified count time of the ACK packet reception counter (the time from the start to the count-up) is indicated as “T2”, and the specified count time of the ACK packet reception counter is also the above-described transmission counter. In the same manner as the specified count time, for example, the time can be arbitrarily set according to the system configuration.

  Further, after transmitting the transmission packet to the terminal station 3, the base station 2 monitors whether or not an ACK packet or a NACK packet has been received from the terminal station 3, as shown in FIG. 11 and FIG. When it is detected that a NACK packet is received from 3, it is also possible to retransmit a transmission packet that was not normally received by the terminal station 3.

  Specifically, when a plurality of transmission packets are received from the base station 2, the terminal station 3 detects that the transmission packet has been normally received for each of the plurality of transmission packets received. When it does, the ACK packet is transmitted to the base station 2 within a specified time. On the other hand, when it is detected that the transmission packet has not been normally received, the NACK packet is transmitted to the base station 2 within the specified time. .

  Accordingly, the base station 2 recognizes that the transmission packet has been normally received by the terminal station 3 by detecting that the ACK packet has been received from the terminal station 3 within the specified time. On the other hand, by detecting that the NACK packet is received from the terminal station 3 within the specified time, it is recognized that the transmission packet has not been normally received by the terminal station 3. When the base station 2 detects that a NACK packet has been received from the terminal station 3, the base station 2 retransmits a transmission packet that was not normally received by the terminal station 3.

Authentication process First, “the base station 2 and the terminal station 3 communicate with each other between the base station 2 and the terminal station 3 by transmitting and receiving beacons, registration packets, and authentication packets as independent data over a plurality of channels. The process of registering and authenticating whether or not the relationship with the station has been established through a plurality of channels will be described with reference to FIG.

  The base station 2 transmits each of the n beacons in synchronization with the terminal station 3 in parallel on n channels as independent data between n channels. In this case, information (BSSID etc.) stored in each of the n beacons is different from each other. Next, when n beacons are received from the base station 2, the terminal station 3 transmits each of the n registration packets in synchronization with the terminal station 3 in parallel on n channels as independent data between n channels. To do.

  Next, when n registration packets are received from the terminal station 3, the base station 2 accepts a registration request from the terminal station 3, and when the registration is normally completed, each of the n registration correct / incorrect packets is changed to n. The data is transmitted in synchronization with the terminal station 3 in parallel on n channels as independent data between channels. Next, when n registration correct / incorrect packets are received from the base station 2, the terminal station 3 synchronizes each of the n authentication packets with the base station 2 in parallel on the n channels as independent data between the n channels. To send.

  Then, when n authentication packets are received from the terminal station 3, the base station 2 accepts an authentication request from the terminal station 3, and when the authentication is normally completed, each of the n authentication pass / fail packets is changed to n. The data is transmitted in synchronization with the terminal station 3 in parallel on n channels as independent data between channels.

Through the processing described above, in each of the n channels between the base station 2 and the terminal station 3, a beacon, a registration packet, By transmitting and receiving a registration correct / incorrect packet, an authentication packet, and an authentication correct / incorrect packet, the base station 2 and the terminal station 3 register and authenticate whether or not the relationship between the master station and the slave station is established through n channels.

The base station 2 and the terminal station can transmit and receive data through multiple channels.
3 and register whether or not the relationship between the master station and the slave station is established with multiple channels and
Next, “the base station 2 and the terminal station 3 can communicate with each other by transmitting and receiving the beacon, the registration packet, and the authentication packet as a common data between the base station 2 and the terminal station 3 through a plurality of channels. The process of registering and authenticating whether or not the relationship with the slave station is established through a plurality of channels will be described with reference to FIG.

  The base station 2 stores a base station identifier individually assigned to each of the n beacons for each base station 2, and each of the n beacons in which the base station identifiers are stored is shared among n channels. Data is transmitted in synchronization with the terminal station 3 in parallel on n channels.

  Next, when n beacons are received from the base station 2, the terminal station 3 recognizes that the base station identifier stored in each of the received n beacons is common to n channels, and n A terminal station identifier individually assigned to each terminal station 3 is stored in each of the registration packets, and each of the n registration packets in which the terminal station identifiers are stored is used as data common to the n channels. Then, the data is transmitted in parallel with the base station 2 in parallel.

  Next, when n registration packets are received from the terminal station 3, the base station 2 accepts a registration request from the terminal station 3, and the terminal station stored in each of the received n registration packets. When the identifier is recognized as common to the n channels and registration is completed normally, each of the n registration correct / incorrect packets is transmitted in synchronization with the base station 2 in parallel on the n channels as independent data between the n channels. .

  Next, when n registration authentication packets are received from the base station 2, the terminal station 3 stores the terminal station identifiers individually assigned to the terminal stations 3 in each of the n authentication packets. Each of the n authentication packets in which the station identifiers are stored is transmitted as data common to the n channels in synchronization with the base station 2 in parallel on the n channels.

  When the n authentication packets are received from the terminal station 3, the base station 2 accepts the authentication request from the terminal station 3, and the terminal station stored in each of the received n authentication packets. Recognizing that the identifier is common to n channels, recognizing that the terminal station 3 is a slave station common to n channels, and making each of the n authentication pass / fail packets n independent data between n channels The n channel is transmitted in parallel with the base station 2 in parallel.

Through the processing described above, in this case as well, in each of the n channels between the base station 2 and the terminal station 3, beacons are transmitted in the same manner as the registration and authentication procedures when transmitting and receiving transmission packets on a single channel. , Registering whether or not the base station 2 and the terminal station 3 have established the relationship between the master station and the slave station in the n channel by transmitting and receiving a registration packet, a registration correct / incorrect packet, an authentication packet, and an authentication correct / incorrect packet. Certify.
(2-3) The beacon, registration packet and authentication packet are exclusively used between the base station 2 and the terminal station 3.
The base station 2 and the terminal station 3 can communicate with each other by transmitting and receiving with a single channel.
Next, the process of registering and authenticating whether or not the relationship with the station has been established over a plurality of channels. Next, “transmitting and receiving beacons, registration packets and authentication packets between the base station 2 and the terminal station 3 using a dedicated single channel. The process of registering and authenticating whether or not the base station 2 and the terminal station 3 have established the relationship between the master station and the slave station through a plurality of channels will be described with reference to FIG.

  The base station 2 stores a base station identifier individually assigned to each beacon in one beacon, and a single channel (in FIG. 15, "F1") to the terminal station 3.

  Next, when a beacon is received from the base station 2, the terminal station 3 recognizes that the base station identifier stored in the received one beacon is common to the n channels and recognizes it as one registration packet. A terminal station identifier assigned to each terminal station 3 is stored, and one registration packet storing the terminal station identifier is transmitted to the base station 2 through a dedicated single channel.

  Next, when a registration packet is received from the terminal station 3, the base station 2 accepts a registration request from the terminal station 3, and sets the terminal station identifier stored in the received one registration packet with n channels. When they are recognized as common and registration is completed normally, one registration correct / incorrect packet is transmitted to the base station 2 through a dedicated single channel.

  Next, when the registration correct / incorrect packet is received from the base station 2, the terminal station 3 stores the terminal station identifier individually assigned to each terminal station 3 in one authentication packet, and the terminal station identifier is stored. One authentication packet is transmitted to the base station 2 through a dedicated single channel.

  Then, when the authentication packet is received from the terminal station 3, the base station 2 accepts the authentication request from the terminal station 3, and uses the n channel for the terminal station identifier stored in the received one authentication packet. The terminal station 3 recognizes that the terminal station 3 is a slave station common to n channels, and transmits one authentication pass / fail packet to the base station 2 using a dedicated single channel.

  By the processing described above, the registration and authentication procedures when transmitting / receiving a transmission packet with a single channel using a dedicated single channel representing the n channel between the base station 2 and the terminal station 3 are performed in the same manner. Whether or not the base station 2 and the terminal station 3 have established the relationship between the master station and the slave station by n channels by transmitting and receiving beacons, registration packets, registration correct / incorrect packets, authentication packets, and authentication correct / incorrect packets. Register and authenticate.

  By the way, the above describes the case where registration and authentication are performed by the same method, but registration and authentication can also be performed by different methods. That is, for example, the above-described method (2-1) is adopted as registration, the above-described method (2-2) is adopted as authentication, and the base station 2 and the terminal station 3 are related to the master station and the slave station. It is also possible to register and authenticate whether or not is established with multiple channels.

  As described above, according to the present embodiment, when the base station 2 transmits a transmission packet to the terminal station 3 in the wireless communication system 1, each of the n transmission packets is divided into the terminal station 3. Instead of transmitting, since each of the n transmission packets is configured to be transmitted to the terminal station 3 in parallel on the n channel as a packet unit, the base station 2 performs processing for dividing the transmission packet or divided transmission packet Can be made unnecessary, and the terminal station 3 can eliminate the configuration for receiving the divided transmission packet, thereby simplifying the base station 2 processing and the terminal station 3 processing. it can.

  Also, as the terminal station 3, not only a station designed to receive transmission packets in parallel on n channels but also a station designed to receive transmission packets on a single channel should be used. The terminal station 3 that receives transmission packets in parallel on n channels and the terminal station 3 that receives transmission packets on a single channel can coexist.

  Further, when accumulation of n transmission packets is completed before the transmission counter counts up, the base station 2 transmits each of the n transmission packets to the terminal station 3 through the n channel in packet units. Since it is configured, it is possible to promptly transmit n transmission packets to the terminal station 3 when the accumulation of n transmission packets is completed. On the other hand, when the transmission counter counts up prior to completing the accumulation of n transmission packets, the base station 2 uses less than n transmission terminals for each of the less than n transmission packets in a packet unit. Since the transmission is made to the station 3, the transmission delay of the transmission packet can be minimized by setting the time that can be allowed as the transmission delay in advance as the count time of the transmission counter.

  Further, since the terminal station 3 transmits the ACK packet to the base station 2 as independent data between n channels when the transmission packet is normally received by the terminal station 3, the terminal station 3 receives the ACK packet. To the base station 2, the base station 2 can recognize that the transmission packet has been normally received from the base station 2, and the base station 2 counts the ACK packet reception counter accordingly. By receiving the ACK packet from the terminal station 3 prior to the upload, it is possible to recognize that the transmission packet transmitted to the terminal station 3 before that is normally received by the terminal station 3.

  When the ACK packet reception counter counts up before the ACK packet is received from the terminal station 3, the base station 2 retransmits the transmission packet that has not been normally received by the terminal station 3 to the terminal station 3. Since the terminal station 3 is configured, even if the transmission packet is not normally received from the base station 2, it is possible to obtain an opportunity to receive the transmission packet that has not been normally received from the base station 2 thereafter. Further, by retransmitting the transmission packet in packet units, a retransmission procedure when a single transmission packet is retransmitted by a single channel can be used, and changes in the communication control procedure can be suppressed as much as possible.

  When the transmission packet is normally received by the terminal station 3, the terminal station 3 transmits the ACK packet to the base station 2 as independent data between the n channels, whereas the transmission packet is normally transmitted to the terminal station 3. 3, since the terminal station 3 is configured to transmit the NACK packet as independent data between n channels to the base station 2, the terminal station 3 transmits the ACK packet or the NACK packet to the base station 2. By transmitting, the base station 2 can recognize whether or not the transmission packet has been normally received from the base station 2, and accordingly, the base station 2 receives an ACK packet or NACK packet from the terminal station 3. By being received, it is possible to recognize whether or not the transmission packet transmitted to the terminal station 3 before that is normally received by the terminal station 3.

  Then, when the NACK packet is received from the terminal station 3 by the base station, the base station 2 is configured to retransmit the transmission packet that has not been normally received by the terminal station 3 to the terminal station 3. Even if the transmission packet is not normally received from the base station 2, the terminal station 3 can obtain an opportunity to receive a transmission packet that has not been normally received from the base station 2. Further, by retransmitting the transmission packet in packet units, a retransmission procedure when a single transmission packet is retransmitted by a single channel can be used, and changes in the communication control procedure can be suppressed as much as possible.

And the terminal station 3 can appropriately register and authenticate whether or not the relationship between the master station and the slave station is established through the n channel.

  Further, in the wireless communication system 1, as a third method for appropriately registering and authenticating whether or not the base station 2 and the terminal station 3 have established the relationship between the master station and the slave station by n channels, 2 transmits one beacon corresponding to each of the n channels to the terminal station 3 using a dedicated single channel, and the terminal station 3 transmits one registration packet corresponding to each of the n channels. One authentication packet is transmitted to the base station 2 through a dedicated single channel, and the base station 2 transmits one registration correct / incorrect packet or one authentication correct / incorrect packet representative for each of the n channels. Since it is configured to transmit to the terminal station 3 with one channel, registration when transmitting and receiving a transmission packet with a single channel with a dedicated single channel representing the n channel between the base station 2 and the terminal station 3 And the authentication procedure, In the same way as the first method and the second method described above, the base station 2 and the terminal station 3 connect the master station and the child station by transmitting and receiving the remote control, registration packet, registration correct / incorrect packet, authentication packet, and authentication correct / incorrect packet. It is possible to appropriately register and authenticate whether or not the relationship with the station is established through n channels.

  In the first method, the second method, and the third method, even if the terminal station 3 is a station designed to receive a transmission packet by a single channel, the base station 2 and the terminal station 3 Can properly register and authenticate whether or not the relationship between the master station and the slave station, and a terminal station 3 that receives transmission packets in parallel on n channels and a terminal that receives transmission packets on a single channel The station 3 can coexist. In addition, registration and authentication procedures when transmitting and receiving transmission packets through a single channel can be used, and changes in communication control procedures can be minimized.
