  Recently, an increasing number of terminals use a wireless local area network (LAN) such as a PC or a mobile phone. For this reason, a situation occurs in which the wireless band used by the wireless LAN is congested. When the base unit and the handset perform wireless LAN communication, communication is performed using a plurality of channels (frequency channels).

  The user sets the plurality of channels in advance so as not to interfere with each other. However, the wireless LAN communication is easily affected by a dynamically changing environment such as the surrounding radio wave environment and the wireless LAN usage status of other terminals. The optimum channel for wireless LAN communication changes according to environmental changes. Therefore, the wireless LAN communication channel may not be optimal due to changes in the surrounding environment even if it is optimal at the time of setting. Patent Documents 1 and 2 show a method of measuring the traffic for each traffic and selecting a line based on the result.

For example, IEEE 802.11, which is a general standard for wireless LAN communication, searches the surrounding situation by the number of beacons received in a certain time. If this method is used, the number of surrounding terminals can be grasped, but it cannot be determined how much traffic is actually generated in which terminal's channel. In addition, this method cannot determine the influence of the physical environment such as the influence of other communication devices on the wireless communication speed.

  The routing unit 15 has a general router routing function. In the present embodiment, the routing unit 15 performs routing between the packet input by the wireless unit 11 and the packet generated by the packet generation unit.

  The packet generator 16 generates a packet to be transmitted by the HGW 10. The packet generator 16 generates a Ping packet. The packet generator 16 uses the Ping packet to measure the response time between the HGW 10 and the terminal 20 belonging to the HGW 10. In this embodiment, Ping is used to measure the response speed, but packets other than Ping may be used as will be described later.

  That is, the assigning unit 111 has a function of selecting and assigning an appropriate channel at an appropriate time based on measurement values (response speed, communication amount).

  As described above, the HGW 10 is a wireless relay device connected to the communication network 50. The HGW 10 is connected to the terminal 20 and the terminal 60, and enables communication with other devices and the like connected to the communication network 50 by the terminal 20 and the terminal 60.

  Next, the terminal 20 in the radio communication system 100 will be described. The terminal 20 is a terminal having a wireless communication function belonging to the HGW 10. In the present embodiment, the terminal 20 has a Ping response function. The terminal 20 has an IP address 102. The IP address of the terminal 20 may be distributed by DHCP by the HGW 10 or may be fixedly set. The basic configuration of the terminal 60 is the same as that of the terminal 20.

In the present embodiment, wireless communication system 100 can assign a wireless communication channel between HGW 10 and terminal 20 and terminal 60, and can communicate using an optimal channel with such a configuration.

Explanation of Processing Next, channel assignment processing of the wireless communication system 200 according to the first embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing channel assignment processing of the wireless communication system 100. The response speed measuring unit 114 measures the response speed of each channel in which the HGW 10 and each terminal are performing wireless communication (S201). Next, the communication amount measuring unit 12b measures the communication amount of each terminal (S202). Next, the assigning unit 111 assigns an optimum channel to each terminal based on the terminal communication information (S203).

  Next, the process of the component of the radio | wireless communications system 100 concerning Embodiment 1 is demonstrated in detail using FIG.

  First, a process in which the wireless communication system 100 measures response speeds of a plurality of channels will be described. FIG. 5 shows a processing sequence of the communication system 100 according to the present embodiment. The HGW 10 is in communication with the terminal 20 and the terminal 60. Consider a case where the HGW 10 and the terminal 20 have already been assigned in ch1. Consider a case where the HGW 10 has an IP address 101 and the terminal 20 has an IP address 102.

  The radio control unit 14 instructs the packet generation unit 16 to generate a Ping packet addressed to the terminal 20 (S101). In addition, the wireless control unit 14 notifies the management unit 13 of the channel currently used by the HGW 10 and the terminal 20 for wireless communication (S102). After receiving the command, the packet generator 16 generates a Ping packet and sends it to the routing unit 15 (S103). The routing unit 15 performs routing of the received Ping packet. Since the present embodiment is addressed to the terminal 20, the routing unit 15 sends a Ping packet to the radio unit 11 (S104).

  The wireless unit 11 that has received the Ping packet from the routing unit 15 transmits the Ping packet to the terminal 20 (S105). Further, the wireless unit 11 notifies the response speed measuring unit 12a that the Ping packet has been transmitted in order to measure the response time (S106). The terminal 20 responds to the Ping packet received from the HGW 10 (S107). The wireless unit 11 receives the response transmitted by the terminal 20 (S108). In addition, the wireless unit 11 notifies the response speed measuring unit 12a that it has been received (S109). The response speed measuring unit 12a measures a time (response time) from when the wireless unit 11 transmits a Ping to when a response is received (S110). The response speed measurement unit 12a transmits the measurement result to the management unit 13 (S111).

The management unit 13 first stores the channel information received from the wireless control unit 14 in association with the measurement result received from the response speed measurement unit 12a (S112). Also, the management unit 13 notifies the wireless control unit 14 that the data has been saved (S113).
Then, the radio control unit 14 transmits an instruction to the radio unit 11 to change the channel used for radio communication with the terminal 20 from ch1 to ch2 to the radio unit 11 (S114). The radio unit 11 changes the channel from ch1 to ch2 (S115). The HGW 10 tentatively connects to the terminal 20 via the channel ch2.

  Through the above processing, the HGW 10 and the terminal 20 are in a state belonging to ch2. Through the same processing as S101 to S1115, the HGW 10 measures the response time at ch2 using the Ping packet. Similarly, the HGW 10 can store the response times of all channels in the management unit 13 at predetermined intervals by measuring the response speed of each channel such as ch3 and ch4. That is, after measuring the response time for each channel, the HGW 10 temporarily allocates a channel with the fastest communication speed to the terminal 20 and connects to the terminal 20. Further, the HGW 10 assigns a channel having the second communication speed to the terminal 60 and connects to the terminal 60. By such processing, the HGW 10 can select an optimum channel and switch the channel based on the measurement result of the response time of each channel.

  Next, a process in which the HGW 10 measures the traffic of a plurality of terminals and allocates channels will be described. The communication amount measuring unit 12b measures the communication amount communicated through the wireless unit 11 with the terminal (S116). The traffic volume measuring unit 12b transmits the traffic volume measurement result to the management unit 13 (S117). The management unit 13 stores the measured traffic data in correspondence with the terminal (S118). In addition, the management unit 13 notifies the wireless control unit 14 that the data has been saved (S119). The wireless control unit 14 reads two pieces of information (terminal communication information) of the traffic data and the response speed stored in the management unit 13 (S120).

  Then, the wireless control unit 14 compares the terminal communication information for each terminal, and transmits a command to the wireless unit 11 to change the channel used for wireless communication with the terminal 20 from ch1 to ch2. (S121). The radio unit 11 changes the channel from ch1 to ch2 (S122). For example, the wireless control unit 14 preferentially assigns the channel ch1 with the fastest communication speed to the terminal 20 that performs the most communication. Then, the radio control unit 14 assigns the channel ch2 having the next highest communication speed to the terminal 60 having the next largest communication volume.

  Moreover, the management part 13 connects terminal communication information and time at the time of preservation | save of terminal communication information. The wireless management unit 14 acquires a tendency of a time zone when there is a lot of communication for each terminal by using this terminal communication information. By analyzing this data, the radio management unit 14 performs a smooth channel selection process such as giving priority to a terminal with a large amount of communication when a predetermined channel is selected and allocated to a terminal at a predetermined time.

  As described above, the wireless control unit 14 can automatically select the optimum channel with reference to the response time of each channel stored in the management unit 13. The wireless control unit 14 transmits an optimum channel to the wireless unit 11 while the system performs wireless communication. Using this result, the radio control unit 14 selects the optimum channel and enables the channel to be changed. Further, the wireless control unit 14 can automatically perform channel design in accordance with the environment by periodically measuring the response time in an environment where the wireless environment is likely to change dynamically.

Description of Effect The wireless communication system 100 measures the response speed of each channel between the parent device and the child device, so that not only the number of surrounding terminals (beacon acquisition information) but also the channel considering the actual radio wave environment Allows design. In addition, the wireless communication system 100 can automatically perform channel design corresponding to a dynamically changing wireless environment by periodically measuring a response speed. Furthermore, the wireless communication system 100 uses Ping for measuring the response speed of the wireless communication system 100, and a terminal belonging to the HGW 10 does not need a special function, and thus is versatile and applied to various wireless communication devices. Is possible.

  Then, in addition to measuring the response speed of each channel between the parent device and the plurality of child devices, the wireless communication system 100 measures the communication amount of the child device connected to the parent device, and the actual radio wave environment It is possible to design a channel that takes into account the traffic of the terminals connected to the. Also, the radio communication system 200 can automatically perform channel design corresponding to a dynamically changing radio environment by periodically measuring terminal communication information.

Embodiment 2
A second embodiment according to the present invention will be described with reference to FIG.
In the first embodiment, when the HGW 10 measures the response speed of the terminal, the measurement is performed while changing the channel. For this reason, the HGW 10 performs measurement while repeating the process of belonging to the terminal for each channel and losing the belonging. As a result, the wireless communication system 100 temporarily disconnects the wireless communication between the parent device (HGW 10) and the child device (terminal). The present embodiment provides a wireless communication system 200 that allows the terminal 20 to connect to the Internet network without disconnecting communication.

  FIG. 6 is a schematic diagram of a wireless communication system 200 according to the second embodiment. As illustrated in FIG. 7, the wireless communication system 200 according to the second embodiment has a configuration in which a speed measurement terminal 70 is added to the wireless communication system 100. In FIG. 7, the HGW 10 and the terminal 70 are connected by both wireless and wired lines. The terminal 20 is wirelessly connected to the HGW 10 and the terminal 70.

  Next, the internal configuration of the wireless communication system 200 will be described in detail. FIG. 7 is a diagram illustrating an internal configuration of the wireless communication system 200. The HGW 10 includes a wireless interface 201 (first wireless line) that wirelessly communicates with the terminal 20 and the terminal 70, a wired interface 202 that performs wired communication with the terminal 70, and a relay unit 203 that connects the terminal 20 and the terminal 70. .

  The terminal 70 includes a wireless interface 204 (second wireless line) that is wirelessly connected to the HGW 10, a wired interface 205 that is wired to the HGW 10, and a wireless interface 206 (first wireless line) that wirelessly communicates with the terminal 20. . With such a configuration, the terminal 70 includes a wireless slave unit function for wireless connection with the HGW 10 and for speed measurement, and a parent unit function for wireless connection with the terminal 20. That is, the terminal 70 is a special terminal for speed measurement.

  The terminal 20 includes a wireless interface 208 (first wireless line) wirelessly connected to the HGW 10 and a wireless interface 207 (first wireless line) wirelessly communicating with the terminal 70. With such a configuration, the terminal 20 includes a slave unit function that is wirelessly connected to the HGW 10 and serves as a slave unit of the HGW 10, and a slave unit function that serves as a slave unit of the terminal 70. The terminal 20 is a terminal having a wireless communication function such as a PC used by a user. The wireless interface 206 and the wireless interface 207 between the terminal 20 and the terminal 70 may use Bluetooth (registered trademark) or other wireless methods in addition to the wireless LAN. In addition, each wireless interface may be configured as one interface in each device. The priority order of the parent device to which the terminal 20 belongs is the order of the HGW 10 and the terminal 70.

Next, processing of the wireless communication system 200 will be described.
The HGW 10 and the terminal 20 belong to the first wireless line. Here, in the communication between the first embodiment and the HGW 10 and the terminal 70, the response speed measuring means 114 measures the speed of each channel using the first radio line. At this time, the wireless control unit 14 performs a first wireless line disconnection process on the terminal 20. When the HGW 10 and the first wireless line are disconnected, the terminal 20 is connected to the terminal 70 through the second wireless line with the terminal 70 having the second highest priority as the parent device.

  The terminal 70 and the HGW 10 are connected by a wired line. Here, the relay unit 203 connects to the terminal 70 via a wired line and relays the terminal 20 via the second wireless line. That is, the terminal 20 uses the second wireless line between the terminal 20 and the terminal 70 and the wired line between the terminal 70 and the HGW 10 while the HGW 10 and the terminal 70 are measuring the speed. As a result, the terminal 20 can communicate with the communication network 50 without disconnecting the communication.

  Next, it is assumed that the speed measurement is completed and the HGW 10 determines the optimum channel. The HGW 10 is waiting for the attribution of the slave unit on the optimum channel. The relay unit 203 performs a process of disconnecting the second wireless line between the terminal 70 and the terminal 20. Next, the assigning unit 111 assigns the optimum channel having the highest priority to the terminal 20. The relay unit 203 switches the connection between the terminal 20 and the HGW 10 to the first wireless line, and the terminal 20 belongs to the HGW 10 via the first wireless line.

Description of Effects As described above, the wireless communication system 300 includes the terminal 70 for speed measurement, so that the terminal 20 can be connected to the Internet network without disconnecting communication.

Embodiment 3
In the first embodiment, Ping is used to measure the response speed. The third embodiment provides a communication system using a packet capable of measuring a response speed other than Ping.

  The wireless communication system 100 uses a special time information packet in which time information for measuring a response speed is embedded, which is a packet other than Ping. Then, the parent device (HGW 10) transmits a time information packet to the child device (terminal 20). The terminal 20 transfers the packet received from the HGW 10 to the HGW 10. The HGW 10 compares the time information of the time information packet received from the terminal 20 with the time of reception, and measures the time taken for communication.

  The time information packet sets the MAC address of the terminal 20 as the destination of the terminal 20 and the IP address of the HGW 10 as the destination of the HGW 10. Then, since the terminal 20 routes and transmits the time information packet to the HGW 10, it is possible to return the time information packet to the HGW 10 without setting a special rule for the terminal 20.

  As another method, a method in which a special rule is set in the terminal 20 and a packet corresponding to the rule is transferred to the HGW 10 may be used. As an example, the terminal 20 transfers the measurement packet transmitted from the HGW 10 to the terminal 20 to the HGW 10. The HGW 10 receives the packet and measures its communication time.

  Further, when a VoIP (Voice over Internet Protocol) function is used wirelessly, time information is included in a timestamp portion of RTP (Real-time Transport Protocol). The wireless communication system 100 can also use a method of measuring delay (response speed) using this time information.

  Further, when the slave unit (terminal) is a PC, a smartphone, or the like, there is a method of installing an application for channel selection according to the type of each slave unit. This application is configured to have a function of measuring a response speed and changing a channel in accordance with the parent device when the child device and the parent device are in a communication state. The wireless communication system 100 can use the channel selection function in a wide range of terminals by communicating with each terminal installed with this application.

Other Embodiments The wireless relay device control method described above may be implemented using a semiconductor processing device including an ASIC (Application Specific Integrated Circuit). These processes may be realized by causing a computer system including at least one processor (eg, a microprocessor, MPU, DSP (Digital Signal Processor)) to execute a program. Specifically, one or a plurality of programs including an instruction group for causing the computer system to perform an algorithm related to the transmission signal processing or the reception signal processing may be created, and the programs may be supplied to the computer.

  These programs can be stored using various types of non-transitory computer readable media and supplied to a computer. Non-transitory computer readable media include various types of tangible storage media.

  Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / W and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)) are included.

  The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire and an optical fiber, or a wireless communication path.
