Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a relay device for radio communication. [Prior Art] "Packet communication" has been used in the past - generally, a communication device conforming to TCP/IP (Transmission Control Protocol/Internet Protocol) is used and a router is used ( A network device such as a router or a switch performs packet transfer between networks. Routers usually connect multiple networks in a wired manner. Moreover, the router sends or forwards the input data packet to other networks according to the transmission destination information contained in the data packet when the data packet sent by the connected network is input. In contrast, there are also wireless routers that connect wirelessly to a plurality of networks. k This wireless routing benefit replaces the interface of the router with a wireless interface (for example, Non-Patent Document 2 and Non-Patent Document 2). In recent years, wireless terminals that users carry have become more diverse, and wireless interfaces that follow a wide variety of wireless communication specifications have been used. For example, a wireless LAN (Local Area Network) or a mobile phone that complies with the Wi-Fi (Wireless Fidelity) (registered trademark) specification (IEEE802.il), and follows the WiMAX (registered trademark) specification (IEEE802). .16) or a wireless terminal (Bluetooth) (registered trademark) specification (IEEE8〇2) 5· i). 321124 201004179 Because there is no interchangeability between the various specifications, wireless terminals with only a specific wireless interface can only connect to the Internet in the area where the corresponding wireless communication specifications are provided. In addition, each of the wireless communication methods has its own advantages and disadvantages. However, it has not been possible to provide communication of a wireless communication standard having a wide communication range and a wide communication range regardless of where it is used. On the other hand, with the increase in the number of wireless terminals that are inherently portable and small wireless communication devices, the communication needs of users using wireless terminals in moving places or moving are also high. However, wireless terminals typically only have a wireless interface that corresponds to a communication specification. On the other hand, wireless communication services that follow various communication specifications are provided in various regions and places (e.g., in stations, commercial facilities, etc.) and their scope is continuously expanded. However, wireless terminals do not accept wireless communication services as long as they have inconsistent communication specifications. However, there is a problem that mobile terminals that are more mobile and more mobile, or mobile communication environments cannot be fully utilized.

The following is the configuration of the implementation of the present invention and the operation of the radio relay device. The electric device (the first embodiment) is configured. The line relay is installed as a relay device of the radio relay station and the external network.... The final WAN (t!^ Zhongxian A1 has communication with the external _ road ( "Network" side communication unit A1〇 (the communication unit LAN (local area network) side communication unit Μ (321124 8 201004179). In addition, the radio relay unit A1 is equipped with a relay function unit. A5 is connected to the WAN side communication unit A10 and the LAN side communication unit All. The data transfer between the WAN side communication unit A10 and the LAN side communication unit A1 is performed; and the interface selection unit A8 selects one of the communication interface faces of the WAN side communication unit A10 for communication. Further, the radio relay device A1 Further, the timer unit A9 notifies the interface selection unit A8 that the predetermined period has elapsed, and the battery unit A6 supplies the power supply for the operation of the radio relay unit A1. The WAN side communication unit A10 has three communication units. The face (the first communication face). These communication faces are: wireless LAN interface face A2, which is connected with the external network to communicate according to IEEE802.11 specification; 3G/3.5G mobile phone face A3 It is connected to the external network to communicate with the 3rd and 3.5th generation mobile phone specifications; and the WiMAX interface A4 is used as the broadband mobile wireless interface for WiMAX-compliant communication. The so-called 3rd and 3.5th generation mobile phone specifications refer to, for example, WCDMA (Wide Band Code Division Multiple Access), HSDPA (High Speed Downlink Packet Access), EDGE (High Speed Downlink Packet Access) Enhanced Data Rates for GSM Evolution; Enhanced GSM Data Transmission). The LAN side communication unit A11 has a communication medium face (second communication medium face). The communication interface is a wireless LAN interface A7 that communicates with the wireless terminal to comply with the IEEE802.il standard. 9 321124 201004179 LAN恻Communication Department All can also have multiple communication interface faces. For example, the LAN side communication unit Al 1 may have a wireless communication face that communicates in accordance with the Bluetooth (registered trademark) standard, and a communication face that communicates in accordance with the ZigBee (registered trademark) specifications. When the relay function unit A5 relays communication data between communication interfaces of different wireless communication specifications, the data format is changed according to the wireless communication standard to be used to transmit the received communication data. Fig. 2 is a schematic view showing transmission and reception of communication data when communication is performed using the radio relay device A1 of the first embodiment. The radio relay device A1 itself is a wireless router, and the wireless LAN interface A7 of the LAN side communication unit All performs transmission and reception of communication data with the wireless terminal device B11. Further, when the radio relay device A1 is located in the wireless LAN service area B4 of the wireless LAN base station B3, the radio relay device A1 communicates with the wireless LAN base station B3 via its wireless LAN interface A2. When the radio relay device A1 is located in the 3G mobile phone area B6 of the 3G mobile phone base station B5, the radio relay device A1 is connected by the 3G/3.5G mobile phone face A3 to the 3G mobile phone base station B5. communication. When the radio relay device A1 is located in the WiMAX service area B8 of the WiMAX base station B7, it is connected to the WiMAX base station B7 for communication. 10 321124 201004179 - When the WAN side communication unit A10 can communicate using a plurality of communication planes, the interface selection unit A8 selects the communication interface to be used for communication. That is, the interface selecting unit A8 selects one of the wireless LAN interface portions A2, 3G/3.5 (3 mobile phone interface face A3, and WiMAX interface face A4 for communication. Fig. 3 shows the selection of the radio relay device A1. Flowchart of the processing procedure of the communication interface. First, the radio relay device A1 is turned on (ON) to obtain the supply of the power source (step S3〇1). The sweat interface selection unit A8 starts the operation. The signal is output to the LAN side communication unit A1. The wireless LAN interface provided in the LAN side communication unit starts operation and starts communication with the wireless terminal Bn (step S3〇2). Next, the interface selection unit A8 detects the base station. The start signal is output to the WAN side communication unit A10. The operation start signal is output from the interface selection unit A8, the wireless LAN interface part 2, the 3G/3.5G mobile phone face A3, and the WiMAX provided in the WAN side communication unit A10. The interface A4 performs the detection of the base station, and outputs the result of the detection to the interface: A8 (step S303). ^ The above communication interface detecting interface selecting unit A8 determines whether there are two detected base stations (step S30). 4) In the case where the WAN side communication unit A10, * two or more communication medium faces have detected the base station (the result of step S304 is "YES,"), the processing of step S305 is performed. In other words, according to the memory in advance The power consumption value of the communication standard used in each communication interface of the interface selection unit as ^, and the A8 selects the communication communication face of the communicable communication interface which is the lowest power consumption communication face (step S305). In the power consumption value of the interface selection unit A8, the communication interface of the 3G/3.5 G mobile phone face A3, the WiMAX face A4, and the wireless LAN face A2 is recorded in order of high and low order. On the other hand, in the case where the WAN side communication unit A10 does not have two or more communication planes capable of detecting the base station (NO in step S304), the processing in step S306 is performed. In other words, the interface selection unit A8 determines whether or not the wireless LAN interface A2, the 3G/3.5G mobile phone interface A3, and the WiMAX interface A4 included in the WAN-side communication unit A10 are all in the out-of-circle state (step S306). In the WAN side communication unit A10, no communication medium can detect the base station, and each communication interface is outside the circle (the result of step S306 is YES), and then the processing of step S303 is performed. In other words, The interface selection unit A 8 outputs the signal for starting the base station detection to the WAN side communication unit A10. Thereafter, the processing of step S303 and subsequent steps is performed. On the other hand, in the WAN side communication unit A10, any communication interface is detected. In the case of the circle of the base station (the result of the step S306 is "NO"), the processing of the step S307 is performed. In other words, the interface selecting unit A8 selects the communication interface portion located in the circle (step S307). The relay function unit A5 performs communication between the communication interface of the WAN side communication unit A10 selected by the interfacing unit A8 and the wireless LAN interface A7 of the LAN side communication unit A1 in step S305 or step S307. 12 321124 201004179 Relay of data (step S308). At the beginning of the relay operation, the timer unit A9 starts counting and outputs a signal indicating that the situation has elapsed for a certain period of time to the interface selecting unit A8. The interface selection unit A8 detects whether or not a certain period of time has elapsed since the start of the relay between the WAN side communication unit A10 and the LAN side communication unit A1 by the signal input from the timer unit A9 (step S309). When a certain period of time has elapsed (the result of step S309 is #YES), the interface selecting unit A8 performs an operation similar to step S303. In other words, the interface selection unit A8 outputs the signal for starting the base station detection, and the wireless LAN interface A2, the 3G/3.5G mobile telephone interface A3, and the WiMAX interface A4 provided in the WAN side communication unit A10 perform the detection of the base station. Thereafter, the processing from step S303 onward is repeated. On the other hand, if the time has not elapsed (the result of step S309 is "NO"), the processing of step S308 is performed. In other words, the relay function unit A5 relays the communication between the communication interface of the WAN side communication unit A10 selected by the interface selection unit A8 and the wireless LAN interface A7 of the LAN side communication unit All. Thereafter, the operation of step S309 is performed again. As described above, the radio relay apparatus A1 selects one of the plurality of communication planes in the communicable circle among the communication planes of the WAN side communication unit A10, and selects one of the power consumption to perform communication. Therefore, the radio relay device A1 can select a communication medium face that consumes less power when a plurality of communication medium faces can be used for communication, and can suppress the consumption of electric power stored in the battery unit A6. 13 321124 201004179 The fixed time counted by the timer unit A9 is set to, for example, 1 minute or 5 minutes. Thereby, in the case where the radio relay device A1 moves, the connection state on the WAN side is detected at a predetermined interval, and the radio relay device A1 can detect the change in the reception state of the communication interface on the WAN side in step S303. . Further, the radio relay device A1 can select the communication medium face to communicate in the case where the communication medium having a low power consumption is in the circle. Therefore, the radio relay device A1 can reduce power consumption. Fig. 4 is a schematic diagram showing an outline of a specific communication operation of the wireless terminal device B11 using the radio relay device A1 of the first embodiment. Here, the radio relay device A1 as the wireless router is placed in the bag taken by the user or placed in the user's pocket, and the user communicates with the wireless terminal device B11 taken along the solid line B2. The path shown is moving. The user moves from the wireless LAN service area B4 indicating the range in which the wireless communication service is provided toward the wireless LAN service area B10 as indicated by the solid line B2. First, the radio relay device A1 is located in the wireless LAN service area B4 that performs wireless communication through the wireless LAN base station B3, and is in a circle that can communicate with the wireless LAN base station B3. Further, the radio relay device A1 is also located in the 3G service area B6 of the service for performing wireless communication through the 3G mobile phone base station B5, and is in a circle that can communicate with the 3G mobile phone base station B 5 . Here, in the radio relay apparatus A1, the interface selecting section A8 enters 14 323124 201004179 to select the communication interface as shown in FIG. 3, and selects the wireless LAN 'interface A2. The radio relay device A1 communicates with the wireless terminal device B11 via the wireless LAN interface A7 provided in the LAN side communication unit A1, and the wireless LAN interface A2 and the wireless LAN access point provided in the WAN side communication unit A10. (access point) B3 for communication. In this way, the radio relay device A1 relays the communication data between the wireless terminal device B11 and the wireless LAN base station B3. Therefore, the wireless terminal B11 can communicate with the wireless LAN base f via the radio relay device A1. Then, the user moves along the solid line B2, and the 3G/3.5G mobile phone face A3 provided in the WAN side communication unit A10 is in the circle, except for the wireless LAN service area B4. The interface selecting unit A8 then selects the 3G/3.5G mobile phone face A3. The wireless terminal unit B11 communicates with the 3G mobile telephone base station B5 via the radio relay device A1. At this time, the radio relay apparatus A1 changes the connection on the WAN side in accordance with the procedure shown in FIG. Therefore, the user is not allowed to have a feeling other than the wireless LAN service area B4, that is, the user can continue the relaying operation without feeling the connection state on the WAN side. Next, the user moves along the solid line B2, and the radio relay device A1 enters the WiMAX service area B8 in which the wireless communication service is performed by the WiMAX base station B7. Therefore, the WiMAX interface A4 provided in the WAN side communication unit A10 enters the circle. Here, the interface selection unit A8 selects the WiMAX interface A4 having less power consumption than the 3G73.5G line 15 321124 201004179 mobile phone interface A3. Therefore, the wireless terminal unit B11 communicates with the WiMAX base station B7 via the radio relay device A1. The user continues to move along the solid line B2 and moves outside the 3G service area B6 and outside the WiMAX service area B8. In this case, since all the communication interface portions of the WAN side communication unit A10 cannot communicate, the radio relay device A1 can no longer relay the communication data of the wireless terminal B11. Therefore, the wireless terminal unit B11 is in a state in which communication is impossible. At this time, the radio relay apparatus A1 repeats the operations of steps S303, S304, and S306 shown in Fig. 3 until any of the communication planes provided in the WAN side communication unit A10 enters the circle. The user continues to move along the solid line B2 and enters the wireless LAN service area B10 for wireless communication service by the wireless LAN base station B9. Therefore, the wireless LAN interface face A2 of the WAN side communication unit A10 enters the communicationable circle. The wireless LAN interface A2 enters the circle, and the interface selection unit A8 selects the wireless LAN interface A2. The interface selection unit A8 selects the wireless LAN interface A2, and the relay function unit A5 relays the communication data between the wireless LAN interface A7 of the LAN side communication unit All and the wireless LAN interface A2 of the WAN side communication unit A10. Therefore, the wireless terminal device b 1J communicates with the wireless LAN base station B9 via the radio relay device A1. As described above, the radio relay device A1 is in the WAN side communication unit A10 16 321124 201004179. • When there are a plurality of communication medium faces in the circle, the communication device that consumes less power is selected to perform the communication data of the wireless terminal device B11. Relay. In this case, the radio relay device A1 can reduce the power consumed and extend the time during which the power supplied from the battery unit A6 can be operated. In addition, by providing a plurality of communication face portions on the WAN side communication unit A10, the wireless terminal device Bu can pass through the radio 〆 relay device even in the area where the communication service is provided in the communication standard where the wireless terminal device Bu cannot be connected. Connect to an external network. (Second Embodiment) The second embodiment differs from the first embodiment in that the interface selecting unit A8a of the radio relay apparatus A1a according to the second embodiment performs the communication interface of the WAN side communication unit A10 in accordance with the moving speed. Department of choice. Fig. 5 is a schematic block diagram showing the configuration of the radio relay device a & The radio relay device Ala selects the communication interface of the WAN side communication unit A10 according to the moving speed I of the own device. The radio relay device A1a is configured to include a moving speed detecting unit A12 in the configuration of the radio relay device A1 of the first embodiment. In the radio relay apparatus A1a, the configuration other than the interface selection unit A8a and the movement speed detecting unit A12 is the same as that of the radio relay apparatus A1 of the first embodiment, and therefore the same reference numerals will be given thereto, and the description thereof will be omitted. Hereinafter, the interface selection unit A8a and the movement speed detecting unit A12 will be described. The moving speed detecting unit A12 detects and memorizes the moving speed of the own device, that is, the radio relay device A1a. The interface selection unit A8a selects which of the communication face portions of the WAN side communication unit A10 to communicate with based on the moving speed input by the group moving speed detecting unit a12. Fig. 6 is a flow chart showing the processing procedure of the selective communication interface of the radio relay apparatus A1a in the second embodiment. First, the radio relay apparatus A1a is turned "ON" in the operation of the user to obtain the supply of the power source (step S6〇1). The interface selecting unit A8a outputs the signal of the start of the operation to the side communication unit All. The wireless LAN interface a in the LAN side communication unit A11 starts to operate and starts communication with the wireless terminal B (step s 6 〇 2). Next, the interface selecting unit A8a outputs the signal for starting the base station detection to the WAN side communication #Α10. The signal for starting the operation is output from the interface selection unit, and the wireless LAN interface, the 3G/3.5G mobile phone interface Α3, and the Μαχ介面μ, which are provided in the WAN side communication unit A, are respectively detected by the base station.

In this way, in the case of a stop, or a slow V ^ walking degree, the communication face with a fast communication speed can be preferentially selected. In the WAN side communication department A1〇, there are more than two channels:: face: the case where the base station can be detected (__(4) is the second choice: the following step S607. In other words, the interface selection unit A10 The wireless LAN is equipped with two or two 5G mobile phone face A3 and WIMAX face A4, all of which are outside the circle (step s6〇7). In the TM side communication part A1〇, it cannot be used in every communication face. 321324 19 201004179 When the base station is detected and is outside the ring that cannot be communicated (YES in step S607), the following process of step S603 is performed.

On the other hand, in the WAN side communication unit A10, any one of the communication interface faces is detected in the circle of the base station (step S607). If the result is "NO", the processing of the following step S608 is performed. In other words, the interface selecting unit A8a selects the communication interface portion located in the circle (step S608). The relay function portion A5 performs the interfacing at step S606 or step S608. select The communication medium between the communication interface of the WAN side communication unit A10 selected by the unit A8a and the wireless LAN interface A7 of the LAN side communication unit All is relayed (step S609). At the beginning of the relay operation, the timer unit A9 When the time has elapsed, a signal indicating that a certain period of time has elapsed is output to the interface selection unit A8a. The interface selection unit A8a detects the communication unit A10 from the WAN side by using the signal input from the timer unit A9. Whether or not a certain period of time has elapsed after the start of the relay between the LAN side communication units A1 (step S610). If a certain period of time has elapsed (the result of step S610 is YES), the interface selecting unit A8a performs the same as step S603. In other words, the wireless LAN interface A2, the 3G/3.5G mobile phone interface A3, and the WiMAX interface A4 provided in the WAN side communication unit A10 perform detection of the base station, respectively, and then repeat steps S603 and subsequent steps.

The field A5 performs a relay step of communication between the communication interface of the communication unit A10 and the wireless LAN π face VIII of the secondary communication unit 51 selected by the interface selection unit. (10) The operation of $. Thereafter, the operation of step S610 is performed again. As described above, in the case where the radio relay apparatus Ala is moving, the wireless, relay apparatus A1a has communication from the WAN side communication unit A1; In a plurality of communication faces in the communication circle, the communication face is selected for communication according to the private speed, and communication is performed. In this case, the radio relay device Ala can select a communication interface with a wide communication range when a plurality of communication interfaces 4 can be used for communication, and can prevent communication of the WAN side communication unit ai〇 due to the movement; When the ι face changes frequently to the out-of-circle state, the wireless terminal device can stably communicate. I- (Third Embodiment) The second embodiment differs from the second embodiment in that the interface selecting unit A 8 a of the radio relay device A 第三 a in the third embodiment performs a communication interface in accordance with the moving speed. In addition to the selection of the department, the processing of the communication interface is selected according to the communication protocol (Prot〇c〇l) used in the 5th hole. The radio relay device Ala is selected as shown in Figs. 7 and 8; Fig. 7 and Fig. 8 are flowcharts showing the processing procedure of the selection of the communication interface portion of the % device A1a in the radio system in the third embodiment. 321124 21 201004179 The steps of steps S701 to S708 perform the same operations as the steps of steps S601 to S608 shown in Fig. 6. Step S701 and step S6 (H, step S702 and step S602, step S703 and step S603', step S704 and step S604, step S705 and step S605, step S706 and step S606, step S707 and step S607, step S708 and step S608, respectively Step S709 is a process of relaying the communication data of the wireless terminal device B11, and is described in detail using FIG. 8. First, at the beginning of the relay operation, the radio relay device Ala enters and waits from the WAN side. The communication and the standby state of the communication from the LAN side (step S801). When the packet is received by the communication interface of the WAN side communication unit A10 (the result of step S801 is "received packet on the WAN side"), the steps are performed. In other words, the relay function unit A5 inputs the packet from the communication interface selected by the WAN side communication unit A10, and outputs the input packet to the wireless LAN interface A7 of the LAN side communication unit A1. Wireless LAN interface The unit A7 transmits the packet to the connected wireless terminal device B11 as soon as the packet is input (step S802). On the other hand, the wireless LAN interface A7 of the LAN side communication unit All When the packet is received (the result of step S801 is "receive packet on the LAN side"), the process of step S804 is performed. In other words, the wireless LAN interface A7 receives the packet (step S804), and determines the protocol used for the packet. When the interface selection unit A8a inputs the communication protocol information 321124 201004179 indicating the communication protocol from the wireless LAN interface A7, the interface selection unit A8a selects the priority of the communication interface that is associated with the movement speed information and the communication protocol information in advance. Selecting the communication interface of the WAN side communication unit A10 (step S805). Here, the priority order for selecting the communication interface that is associated with the communication protocol information in advance is that the transmission amount of the communication data is large. The communication protocol can use the order of wider communication bandwidth to establish the superiority. The communication protocol with a large amount of communication data is, for example, FTP for file transfer (File Transfer Protocol; ), RTSP (Real Time Streaming Protocol) for streaming data (Stream) In this case, the priority order is the order of WiMAX interface A4, wireless LAN interface A2, 3G/3.5G mobile phone face A3. In addition, in the case of a communication protocol with a small amount of communication data transmission The priority order is the order of the 3G/3.5G mobile phone interface I, the part A3, the wireless LAN interface A2, and the WiMAX interface A4, which are opposite to the above. A communication protocol having a small amount of transmission of communication data includes, for example, VoIP (Voice over Internet Protocol) for voice communication. The relay function unit A5 inputs the packet from the wireless LAN interface A7 of the LAN side communication unit A1, and outputs the input packet to the communication interface of the WAN side communication unit A10 selected in step S805. The communication interface of the WAN side communication unit A10 transmits the input packet (step S806). Next, the interface selection unit A8a detects whether or not the _ π π of the communication unit A11 has passed through the relay from the WAN side communication unit Ai by using the signal 23 321124 201004179 input from the timer unit A9. — 士 g 疋 time (step S803) 〇 already... a certain time (step) “Yes,,”, the interface selection unit A8a ends I, and the result is that the communication data is relayed, and then In the figure shown in Figure 7, the shoulders are in the middle of the 7th 丄 丄 + MS7 〇 3 after the action.

Therefore, the interface selection unit selects the communication interface corresponding to the communication data developed by the wireless terminal B11, and can perform communication data without securing the unnecessary communication frequency. Send In addition, in the process of selecting the communication interface, the processing of selecting the communication interface according to the moving speed of the radio relay device A1 may not be included. In this case, the communication interface of the WAN side communication unit A10 is used, for example, before use. The communication interface is used, or a predetermined communication interface is used, and then the communication interface of the WAN side communication unit A10 is selected according to the communication protocol after the start of the relay. (Fourth Embodiment) Radio Relay in the fourth embodiment The device Alb is different from the first to third embodiments in that the wireless side of the LAN side communication unit A11 is 24 321124 201004179 • the communication operation performed by the LAN interface A7. Fig. 9 shows the radio in the fourth embodiment. A schematic block diagram of the configuration of the splicing frame 。. The radio relay device Alb has a configuration other than the relay, the functional unit (10), and the sleep time calculating unit Απ, and the radio in the first embodiment of the first and second embodiments. Since the device A1 is the same, the same reference numerals will be given thereto, and the description thereof will be omitted. The following is the case of the relay function unit A 5 b and the sleep time meter f for different configurations. The communication unit A3b performs the transfer of the communication data between the purchase side communication unit ai〇 and the (4) side center red ANn. Further, the relay function unit side passes ==:=, =TM is reserved. The average communication speed of time is rounded up to the middle of the communication between the two faces of the communication device. The communication data is sent out according to the change of the receiving material form. The fabric (4) surface axis specifications are carried out. The line calculation unit 13 calculates the wireless LAN interface portion A10 to the wireless LAN interface Α7ϋ 々 sleep time based on the communication bandwidth 盥-frequency bandwidth of the LAN-side communication unit's benefit line LAN interface A7. The line of transmission LA Α Α Α Α Α 7: The sleep time of the stomach is the time of no news. If the H terminal does not pass between, the dormant phase is calculated as described in "The following." 321124 25 201004179 First, the ratio of the maximum communication speed based on the specification of the communication interface selected by the WAN side communication unit A10 to the maximum communication speed set by the IEEE802.il of the wireless LAN interface A7 is calculated. This ratio is used as the communication speed ratio, that is, (the communication speed is higher than the output (the maximum communication speed of the communication unit A1〇)/(the maximum communication speed of the wireless LAN interface A7). The communication speed ratio is less than one. It indicates that the communication bandwidth of the LAN side communication unit A1 is wider than the communication bandwidth of the WAN side communication unit A10. At this time, there is a communication band that is not used for communication data transfer in the communication bandwidth of the LAN side communication unit All. For example, the 3G/3.5G mobile phone interface A3' is selected in the WAN side communication unit A10 and the 3G/3.5G mobile phone interface face A3 follows the WCDMA standard, and the wireless LAN interface A7 follows the IEEE802.11b case, and the WAN side communication unit The maximum communication speed of A10 is 384Kbps, and the maximum communication speed of wireless LAN interface A7 is 11Mbps. The communication speed at this time is as follows: (communication speed ratio) = (384Kbps) / (llMbps) = (0.035). At this time, LAN Nearly 90% of the communication band of the side communication unit All is not used for the transfer of the communication data. Here, the wireless LAN interface A7 uses the communication speed ratio calculated by the sleep time calculation unit A13 to (sleep ratio)=1-( Communication speed ratio) The wireless LAN interface A7 does not transmit and receive in the communication band not used for communication data transfer according to the input sleep ratio to reduce power consumption. Fig. 10 shows the compliance with IEEE802.11 in the fourth embodiment. The outline of the operation of the wireless LAN interface A7 of the LAN side communication unit A1 of the specification 26 321124 201004179.

Here, the wireless LAN 'section A7 calculates the sleep period F3 by multiplying the sleep ratio input from the sleep time calculation unit A13 by the beacon period interval. During this sleep period, the F3 is a period in which the wireless LAN interface A7 is not waiting for transmission and reception. The radio relay device Alb sets the sleep period in the duration block of the CTS-self (Clear To Send-self) frame F2, and then transmits the CTS-self frame F2 to the wireless terminal set B11. The wireless terminal unit B11 sets the sleep period F3 set in the duration field included in the received CTS-self frame F2 as the NAV (Network Allocation Vector) period F4. When the wireless terminal set B1 sets the NAV period F4, it is not in the NAV period (the transmission of the communication material is performed. In other words, the wireless LAN interface A7 enters during this period: does not receive the communication material, and makes the reply in order to end after the sleep period ends. The deep sleep mode in which all the circuits other than the minimum required for receiving the state of the communication data are stopped. Thereby, the wireless LAN interface A7 can reduce power consumption and extend the radio relay device. The time during which the Alb operates using the battery unit A6. In addition, when calculating the communication speed ratio, the communication speed of each communication can be used without using the maximum communication speed of each communication interface, and the communication speed of each communication in the predetermined most recent period is used. In this case, the sleep period is calculated based on the reception sensitivity of the radio that changes in accordance with the position of the radio relay apparatus Alb, and the power consumption can be reduced in accordance with the state of the communication, and the power can be used efficiently. In addition, the sleep period calculated by the wireless LAN interface A7 can be compared to the CTS-self frame F2. In the case where the predetermined period is long, the wireless LAN interface A7 divides the calculated sleep period into a plurality of periods, and sets the divided sleep period to the duration field of the plurality of CTS-self frames F2. Therefore, the wireless LAN interface A7 can enter the sleep mode or the deep sleep mode between the calculated sleep periods. In addition, in order to enable the wireless terminal B1 to set the NAV period F4, the wireless LAN interface A7 can also be in the beacon signal. The duration field of the box sets the sleep period. Moreover, when the sleep period exceeds the value that can be set in the duration field of the beacon frame, the wireless LAN interface A7 divides the calculated sleep period into a plurality of times. And set to the duration field of the plurality of beacon frames. Thereby, the wireless LAN interface A7 can enter the sleep mode or the deep sleep mode between the calculated sleep periods. (Fifth Embodiment) In the fifth In the radio relay device Ale of the embodiment, although not shown, the wireless LAN interface A7 is replaced, and a communication interface having a multi-connection method with time-division (for example, a WiMAX interface) is provided. In the same manner as the radio relay device A1b of the fourth embodiment, the calculation unit A13 calculates the sleep period and outputs the sleep period to the WiMAX face A14. The WiMAX face A14 is based on the input sleep ratio. In the communication band that is not used for communication data transfer, transmission and reception are not performed to reduce power consumption. Fig. 11 is a diagram showing the WiMAX interface of the LAN side communication unit All following the WiMAX (IEEE802.16) standard in the fifth embodiment. A schematic diagram of the operation of the unit A14. As shown in the figure, each frame G6 includes a sequenced signal Bch (Broadcast Channel) G1, a downlink frame (downlink frames G2 and G3), and a downlink frame and an uplink frame. During the period of TTG (Tx/Rx Transition Gap; transmission/reception transition gap), uplink frame (uplink subframes G4 and G5), RTG (Rx/Tx Transition Gap) as the period for switching the uplink frame and the next frame ; Receive / transfer conversion gap).

Further, the WiMAX interface A14 sets a dummy frame period G3 during a period in which it is not allocated to the wireless terminal device B11 for transmission in the downlink frame, and notifies the wireless terminal device B11. The wireless terminal transmits the communication data in the allocated period G2. The transmission operation is not performed during the dummy frame period G3. Therefore, the WiMAX interface face A14 can enter the sleep mode state during the dummy frame period. In addition, the WiMAX interface A14 also sets a dummy period 29 321124 201004179 frame period G5, thereby allowing the G5 to enter the sleep mode state during the dummy frame. As a result, the WiMAX interface A14 can reduce power consumption, and the time during which the radio relay device Ale operates using the battery unit A6 can be extended.
