Description of the Invention: [Technical Field of the Invention] The present invention relates to a mobile communication system in a DS-CDMA (Direct Spread-Code Multiple Division) system or the like The wireless relay used. [Prior Art] In a mobile communication system, a wireless relay device for relaying a wireless signal to a relay is provided between a base station (BS: Base stati〇n) and a mobile station (MS: Mobile Station). In this way, it is possible to improve the communication environment of a region (so-called blind zone) where radio waves are difficult to reach. In this way, the area covered by the base station can be expanded without the need to construct a new base station. Patent Document 1 discloses a wireless relay device for the purpose of reducing the power consumption of the ▲ clothes in the wireless, and reducing the operating power of the amplifier when there is no signal to be relayed. Specifically, the patent document discloses that the wireless relay device receives the wireless signal transmitted by the wireless communication station of the relay source, and amplifies the received signal by the amplifier and transmits it to the wireless communication station of the relay destination. In this case, the wireless relay device disclosed in Patent Document 1 reduces the operating power of the amplifier for signal amplification when the signal power of the received signal before being input to the amplifier is less than a predetermined threshold level. Or set the action power to zero (z(10)). In other words, the wireless relay device disclosed in Patent Document 1 determines that the relay in the direction of the uplink (uPlink) that has not been received from the mobile station to the base station is not received based on the number of the transmitted and transmitted numbers. In the case of the target signal, the amplification of the relay target signal with 5 319522 200814584 = line direction is transmitted to the base station; i is also #利文! The disclosed wireless relay device does not (4) the downlink key transmitted from the base station to the mobile station ^ (Wnlmk) side (four) relay object signal, used to forward the relay target signal in the downlink direction The amplifier that the station is transmitting stops. [Brief Description of the Invention] The wireless relay device disclosed in Patent Document 1 is independently stopped from the base in February: "the downlink direction of the station" Relay processing, and stopping the relay processing from the power-on port to the uplink direction of the base station. Therefore, the disclosed wireless relay device cannot provide a mobile body even in the absence of a base station or a base fault or the like. In the case of the communication service, the relay operation of the signal transmitted by the mobile station can also be followed. Therefore, the 中继 &# % ^ Θ..., , slice, and 4唬 are transmitted by the line relay device. It exists in the wireless relay device attached to, /, the interference wave of his wireless system.

Here, the downlink amplifier is for amplifying a downlink reception signal received by the base station side receiving antenna. The above action The station side transmission antenna is used to output the signal amplified by the downlink amplifier to the mobile station of the relay destination. The foregoing uplink amplifying system is used to amplify the uplink received signal received by the receiving antenna on the receiving side of the action thunder. The base station side transmission line system is configured to amplify the uplink line: the amplified signal is output to the base station of the relay destination. The pre-relay control segment detects that the signal is not received from the aforementioned downlink received signal to indicate the presence of the base station from the base station. Amplification relay of the signal and amplification relay of the aforementioned uplink received signal. According to this configuration, "there is no detection of the existence of the base station transmitted from the base station" (for example, W-CDMA (Wideband - Code Dmsion Multiple Access; In the case of this general production, s, and, the way to enter, h, general 曰 曰 通 ( ( ( ( nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn nn In the downlink direction, the link direction relaying process can also be performed.

[Embodiment] The t t ... and the drawings are directed to the specific implementation to which the present invention is applied. In the drawings, the same elements are added to the same elements and are confirmed by the five brothers (fourth). Therefore, the overlapping descriptions are omitted as needed. _ (Embodiment of the invention), and the wireless relay attack system of the present embodiment A device for performing U-hull relay between a base station (BS) and a mobile station (ms) in a w_cdma mode wireless communication system. The configuration of the wireless relay device 1 is shown in the second satellite, and the signal relaying device 1 of the downlink station of the mobile station to the mobile station is connected to the base station by the base station side antenna 1 The signal 'is transmitted' and amplified by the amplifier 14 is transmitted by the action = station side antenna 11. On the other hand, when performing signal relay from the mobile station to the uplink of the land station, the wireless relay device! The transmission signal of the mobile station is received by the moving station side antenna 11 by 319522 13 200814584 =, and the received signal is amplified by the amplifier 15, and then transmitted by the base station side antenna 1 . Hereinafter, each component shown in FIG. 1 will be described. * In Fig. 1, the base station side antenna 10 is an antenna for receiving signals transmitted from the base station and transmitting signals to the base station. Further, the mobile station side antenna 11 is an antenna for transmitting signals to and from the mobile station. A duplexer 12 is provided to share the base station side antenna 10 in reception and transmission. Specifically, the # of the downlink frequency band (for example, 21 GHz band in W_CDMA) received by the base station side antenna is allocated to the amplifier 14. Further, the duplexer 12 outputs a signal of an uplink frequency band (for example, a range of 19 (}1^ in W_CDMA) input to the amplifier 15 to the base station side antenna 10. Further, the worker 13 is further set to It is used to share the mobile station side antenna 11 in reception and transmission. Specifically, the signal of the frequency band of the 肇 uplink received by the mobile station side antenna n is distributed to the amplifier 15. Further, the duplexer will be from the amplifier 14. The signal of the downlink frequency band input via the switch 16 is output to the mobile station side antenna 11. The amplifier 14 is used for the amplification of the power amplification in the frequency domain range of the downlink key for inputting the duplexer 12 The signal power of the signal is amplified and output. Further, the amplifier 15 is an amplifier that performs power amplification in the frequency domain of the uplink to amplify and output the signal power of the signal that is input by the duplexer 13. The 16 series is arranged to electrically connect the amplifier 14 and the duplex crying 13 to the line η of the signal detecting portion 17 of the 319522 14 200814584 === system=== description. Used to control amplification That is, the electrical connection between the switch 16 system state and the mobile station side antenna 11 is not correct: :: 2 :, 17 is determined by using the turn-off signal of the amplifier 14; The relay signal (that is, the gate κ + that is opened when the relay station transmits a downlink signal that should be relayed when the switch does not exist, so that the output signal of the amplifier 不会 does not move, and The control by the signal detecting unit 17 and the four-off control are performed based on the switch control signal S1. One of the outputs of the = output signal and the down-link signal is one of the components, and the amplifier 14 is used. The gain is substantially the same as that of the fixed gain amplifier, and the output of the amplifier 14 is compared with the predetermined threshold level. The body is amplified and the output signal of the benefit 14 is compared. When the limit value is still large, the second measuring unit 17 closes the switch 16 to output the output signal of the amplifier 14 and the working station side antenna η. On the other hand, the rim of the 14 is transmitted to the taste > ^大益△衿 "Hu power is less than the predetermined threshold, The signal detecting unit transmits the open switch 16 to thereby disconnect the amplifier 14 from the duplexer 13. However, in the above simple configuration, the presence or absence of the downlink signal to be relayed is determined to be very good. For example, in the case where there is an obstacle wave in the (4) of the downlink key, the output signal power of the amplifier 14 exceeds the threshold level because the wave is prevented from being amplified, even if there is no 319522 15 200814584 The downlink signal of the middle and the 纟k may also perform relay processing. To prevent such malfunction, it is preferable to use the inverse signal of the signal transmitted by the base station for the output signal of the amplifier 14 and then use it. The inverse, diffused signal is used to determine the presence or absence of a downlink signal. Specifically, it is only necessary to perform inverse diffusion processing for demodulating the pilot signal transmitted by the base station over time. The second diagram is a configuration example of the signal detecting unit 14 that does not determine whether or not the pilot signal transmitted from the base station is present.

The diffusion code generation unit 144 supplies a diffusion code common to the diffusion code (specifically, the channelization code 16 319522 200814584 and the scrambling code) used in the diffusion processing of the CPICH in the base station to the cpiCH inverse. Diffusion portion 143. The signal level determining unit 145 compares the signal power of the signal narrowed by the inverse diffusion processing in the CPICH inverse diffusion unit 143 with a predetermined threshold value, and outputs the switching control based on the comparison result. Signal S1. More specifically, the signal level determining unit 145 outputs the switch control signal S1 闭合 such that the switch 16 is closed when the signal power after the reverse diffusion process is greater than a predetermined threshold, and is smaller than a predetermined threshold. Then the switch 16 is opened. Further, the threshold value applied to the signal level determining unit 145 is preferably set to a power level in which the processing gain of the inverse diffusion of the CPICH is considered (that is, the inverse diffusion using the spreading code corresponding to the CPICH is performed, Thereby, the signal power of the interference wave other than the CPICH is reduced to an average of one of the spread factor. Therefore, the presence or absence of the downlink signal to be relayed is determined by the presence or absence of the back-spread cpicH, whereby it is possible to suppress the erroneous determination when the downlink frequency band has an obstacle wave. • As described above, the wireless relay device 1 of the present embodiment determines whether or not the downlink signal to be relayed is determined by using the signal amplified by the source 14. Thereby, even in the case where the signal power of the received signal received by the base station is extremely small, the wireless relay device j can acquire the signal power required for the determination of the presence or absence of the downlink key. Therefore, compared with the configuration of determining whether or not the signal to be relayed is determined by the signal value of the received signal before amplification, the boosting should be performed with respect to the accuracy of the signal to be relayed. Further, the wireless relay device 1 is configured such that when there is no signal to be relayed, the connection between the occlusion amplifier 14 and the mobile station side antenna u is 319522 17 200814584. Therefore, it is possible to stop the operation of the second direction amplifier 14 in the downlink direction without stopping the relay of the helmet. In other words, since the wireless relay device does not need to perform the gain change control of the amplifier 14, it can be used, and the simple configuration of the amplifier can be reduced in cost. Further, when the wireless relay apparatus shown in FIG. 2 adopts a configuration in which the gain of the amplifier is changed according to the reception level, the gain of the amplifier or the gain of the amplifier cannot be sufficiently changed in the case where the signal level of the frequency reception signal fluctuates. Follow-up: The secret number is changed, but this problem can be solved by using the simple configuration of the amplifier used. (Another embodiment) The relay device 1 is configured to control the amplifier 14 by controlling the signal S1 according to the control signal S1 to control the electrical connection between the amplifier 14 and the mobile station side antenna U. / The electrical connection between the antenna side of the electric port side is also: r is amplified... The port is to be in the absence of = α can be placed in the case of the device. In this configuration, the person, when the CPICH is not detected It is possible to reduce the attenuation amount of the variable attenuator when the CPICH is detected, and to make the amplifier included in the wireless relay device 1 two-to-blood-transparently fixed. However, the amplifier 14 amplifies, for example, the amplifier 14 as a variable gain; the gain control 俾 causes the output signal power of the amplifier 14 to be ', p into the so-called AGC (AUt〇matieGainC() ntn) 1; From 319522 18 200814584 dynamic gain control)). • The above-described wireless relay device 1 is configured to stop only the signal relay in the downlink direction depending on the presence or absence of a signal to be relayed, but may be configured to 'depend on the presence or absence of a signal to be relayed. And stop the signal relay of the uplink key. The wireless signal in the downlink direction and the uplink direction is configured to be based on whether or not the downlink signal to be relayed is specifically based on whether or not the pilot signal transmitted by the base station can be detected. County Zan 2 is shown in Figure 3. The switch 26 of Fig. 3 is provided on the wiring for connecting the amplifier 15 and the duplexer 12, and the amplifier 15 and the base station side antenna 1 are connected based on the switch control signal S1 output from the signal detecting portion ρ. A circuit that electrically connects or disconnects between turns. ...the description of the wireless relay device is used as the wireless relay device used in the w_CDMa wireless communication system. (4) It can also be applied to the Cdma2000 system, etc. CDMA mode. In addition, it is not limited to the DS_CDMA method, and can also be applied to other direct diffusion wireless communication systems and other wireless communication systems. (Embodiment 2 of the Invention) The wireless relay device 3 of the present embodiment is configured to perform signal relay between a base station (Bs) and a mobile station (na) in a w_cdma matrix, a line communication system, and a system. Device. The configuration of the wireless relay device 3 is shown in FIG. 4: The wireless relay device 3 receives the base station by the base station side antenna 1〇, and is included in the downlink link relay unit 34. The amplifier (4) 319522 19 200814584 amplifies the received signal and transmits the amplified downlink signal by the mobile station side antenna u. Thereby, signal relaying from the base station to the (four) station in the downlink direction is performed. Further, the wireless relay device 3 receives the developed signal of the battery port by the mobile station side antenna 11 and amplifies the received signal by the amplifier 351 included in the uplink link relay unit %, and is amplified by the base. The station side antenna transmits the amplified uplink signal. Thereby, signal relay from the mobile station to the base station in the uplink direction is performed. Hereinafter, each constituent element shown in the fourth port diagram will be described. In the fourth diagram, the base station side antenna, the line 10, the mobile station side antenna 11, the duplexer 12, and the duplexer 13 are connected to the above-described embodiment of the invention. The downlink relay unit 34 has an amplifier 341. And a switch 342. The amplifier 341 is amplified in the downlink frequency band to amplify the signal power of the signal input by the duplexer 12, and the switch 342 is set in the 甩 to connect the amplifier 341 and the duplexer. 13 connected between the wiring. _ 3 4 2 is a circuit for electrically connecting or disconnecting the amplifier 341 and the mobile station side antenna according to the relay control unit 37 = return (four) control signal S1 to be described later. That is, the open relationship is a circuit in which the downlink (fourth) path of the downlink _ 34 is processed to stop the signal input from the amplifier 341 to the mobile station side antenna u to cover the fe/f. 315 and switch 352. The uplink relay unit 35 has an amplifier 319522 20 200814584 $Day 351 is used for amplification of power amplification in the uplink frequency band. The signal power of the 3 input signals is amplified and output. The switch 352 is disposed on the wiring for connecting the amplifier 351 to the duplexer 12. The switch 352 is a circuit that electrically connects or disconnects the amplifier 351 and the base station side antenna ι according to the control signal S1 output from the relay control unit π, which will be described later. In other words, the switch is a circuit for interrupting the signal input from the amplifier 351 to the base station side antenna 1G in order to stop the uplink relay processing by the uplink relay unit 35. In addition, the amplifiers 341 and 35 can be used as a variable gain amplifier having an AGC f path for controlling the amplification of the signal power, or as a fixed gain amplifier with a substantially fixed booster cup. The operator identifies the operator identification information in the downlink signal sent by the base station. Here, the so-called business identification information system refers to information for identifying a communication provider that provides a mobile communication service. That is, the operator identification information transmitted by the base station is used to display the signal of the presence of the base station and is a signal of the communication provider for displaying the transmission source of the signal. For example, in the case of the W-CDMA system, the notification information including the PLMNid (Public "Μμ〇μ^ Network identifier; network identification number) shown in Fig. 6 is transmitted from the base station. In addition, the PLMNid contains the country code (MCC: c〇untry c〇de; mobile phone country code) and the operator code (MNC: Mobile Network Code; action 319522 21 200814584 telephone network code). Therefore, the PLMNid can be used as the operator identification information. The notification information including the PLMNid is included in the BCH (Broadcast Channel) of the Common Transport Channel as the downlink side. Further, the BCH is transmitted from the base station using P_CCPCH (Primary Common Control Physical Channel) which is a Common Physical Channel of the downlink direction. The relay control unit 37 compares the operator identification information obtained by the company identification information acquisition unit 36 with the comparison information. Here, the comparison information is used to verify whether or not the company identification information obtained by the company identification information acquisition unit 36 is information indicating that the operator is the target of the signal relay. Specifically, it is only necessary to use the operator identification information corresponding to the operator who should be the target of the signal relay as the comparison information. As an example, when the W_CDMA system is used, the PLMNid corresponding to the operator who should be the target of the signal relay may be used as the comparison information. Further, the relay control unit 37 controls the operations of the switches 342 and 352 by the control signal S1 based on the comparison result between the operator identification information and the comparison information. Specifically, when the operator identification information matches the comparison information, the relay control unit 37 closes the switches 342 and 352 to relay signals in the downlink direction and the uplink direction. On the other hand, when the operator identification information does not match the comparison information, the relay control unit 37 opens the switches 342 and 352 to stop the signal relay in the downlink direction and the uplink direction. The power supply unit 38 inputs a commercial alternating current source such as AC100V or AC240V to perform voltage conversion, rectification, and smoothing, and then supplies operating power to each unit included in the wireless relay device 3 22 319522 200814584. The receiver's description of the operator identification information acquisition unit 36 is explained. The operator identifies the capital, and the "body configuration example is added. In the case of (10), the configuration example shows... frequency-signal. Specific: =: is a diagram), local oscillator (not shown), low-pass Waves, = > Kunsaki A/D converter (not shown). She 乂 (not shown), and, :: τ and local oscillator _;:::=^ will be in the low-pass filter The output signal of the mixer is performed: In the A/D converter, the low-pass-mike signal is sent in and out of the sampled digital signal. The sub-input matching filter 361 is taken by the corresponding P_CCPCH replica (replica) The correlation calculation of the input signal is performed to perform the inverse diffusion code generation unit 362 to output the common diffusion code (specifically, the channel code and the scrambling code) used by the base station at p_ccpcH = to the matched filter 361. (4) The matching chopper 3M performs inverse diffusion processing by a correlation operation corresponding to the input signal of the diffusion replica disk having cpiCH. The diffusion code is generated; the 364 system output is common to the diffusion code used by the base station in the CPICH diffusion processing. The diffusion code is matched to the matched filter 363. The channel estimation unit 365 uses the matched filter 363. The output signal is used for channel estimation, and generates a delay profile corresponding to a multipath (base) between the base stations. The rake synthesis unit 366: uses the delay profile measured by the channel estimation unit 365 to perform rake 319522 23 200814584 Synthesis The BCH decoding unit 367 performs de-interleaving and channel decoding on the RAKE-combined data sequence to decode the BCii. The PLMNid extraction unit 367 extracts the decoded information from the decoded BCH. PLMNid As described above, the wireless relay device 3 of the present embodiment is in the case of the downlink direction and the uplink direction when the operator identification information included in the downlink signal signal does not match the previously held comparison information. Signal relay. That is, it can be determined that the carrier using the wireless frequency band to be relayed by the base station has been changed, and the downlink direction and uplink are stopped based on the determination result. In addition, the wireless relay device 3 of the present embodiment is based on the operator included in the downlink key The comparison result of the other information not only the downlink direction, but also the signal relay in the uplink direction, that is, the service is stopped at the base station, the base station fails, and the allocation of the wireless communication is changed. Can not mention #乡...,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, Therefore, in the wireless relay device 3, the relays 7m A and k of the signals of the two signals do not become obstacle waves of other wireless systems in the presence of two. In addition, the power supplied by the wireless relay-stream power supply of the present embodiment comes in:: It is used by most of the commercial equipment manufacturers, and it is difficult to set the general traffic user 34 home and material t #, can == Body communication service (another embodiment) A wireless relay device is also provided. 319522 24 200814584 The above-mentioned wireless relay device 3 is also a carrier frequency that changes the downlink link signal transmitted to the mobile station, the frequency conversion of the younger brother, and the downlink signal of the wide _ phase Angu t. = 'The change of the uplink signal t 7 F1 ^ - λα ^ transmitted to the base station is shown in Fig. 7. Two: = The wireless relay device 4 is not provided with a frequency conversion (10), a carrier frequency of the two-way signal, and a frequency conversion unit 453, which is a carrier frequency of the St. According to this configuration, even when the allocation of the second/! communication range is changed, and the radio band in which the base station is replaced by the base station is changed, the action X is performed by using the radio band before the change. communication. Therefore, the signal of the hotline band after the genus is transmitted to the mobile station side, and the signal after the suppression band is changed becomes the interference wave of the other wireless system existing around the wireless relay device. In the above-described hot line relay device 3, the relay control unit 37 2 holds a plurality of pieces of comparison information, and the received downlink information = the business information and the plurality of comparison information. Signal relay can also be performed when any one is consistent with the poor news. In addition, the wireless relay device 3 described above may be configured to hold a list data (tabl "ata" for displaying the correspondence relationship between the # identification information and the carrier frequency shown in the figure 8 and to identify the information based on the operator. The carrier frequency applied to the transmission of the downlink signal and the reception of the uplink signal is changed. A variation of the wireless relay device 3 is shown in Fig. 9. The wireless relay device 5 shown in Fig. 9 is maintained. The list data shown in FIG. 8 is determined based on the received business identification information (PLMNid). The change of the carrier frequency is 319522.25 200814584. Next, the relay control unit 57 of the hot line relay device 5 is used for output. The control signal S2 indicating the change of the carrier frequency is used. The frequency conversion units 3 4 3 and 3 5 3 of the radio = relay device 5 change the carrier frequency according to the control signal § 2. ^ Further, the above-described wireless relay device (3) Although the PLMNid included in the notification information from the known base station is used as the identification information of the operator, the composition of the information is only an example. That is, the identification information of the operator is not limited to the pLMNid, and may be identifiable. Further information of the above-mentioned wireless relay device 3 uses switches 342 and 352 as a circuit for blocking the signal input from the amplifier 341 toward the mobile station side antenna u and for using the amplifier 351 toward The signal input to the base station side antenna 10 is blocked. However, the configuration for blocking the signal input is not limited to the switch for controlling the electrical connection state and the 3^2. For example, the fading can be changed. The variable attenuator is placed on the wiring between the 341 舁 mobile private side antenna 丨, and the wiring between the amplifier 351 and the base station side antenna 10. In this case, the operator When the comparison result of the identification information is inconsistent, the attenuation amount of the variable attenuator may be reduced. Further, in the case of the configuration of the preamplifier of the amplifier 341, the operator is employed. When the result of the comparison of the identification information is not correct, the gain of the amplifier 341 can be reduced. - Further, the above-described wireless relay device 3 transmits the base station side antenna 10 and the mobile electric port side antenna 11 It is shared at the time of reception, but the transmitting antenna and the receiving antenna can be independently set. The above-mentioned wireless relay|setting 3 is configured to be a commercial exchange. 319522 26 200814584 The package originally operates, but may be configured by In place of this configuration, the power supplied from the DC power supply device of the external port p such as the DC stabilized power supply is operated.
