ision Multiple Access )方式を採用する場合にも、同様に生じる問題である。 When employing the ision Multiple Access) scheme it is equally caused problems.

【0007】 [0007]

【発明が解決しようとする課題】従来においては、大ゾーン方式を採用すると、周波数や拡散符号などの無線資源の利用効率が低く、収容できるユーザ数が少なく、一方小ゾーン方式を採用すると、ハンドオーバの発生頻度が高く、過大な処理能力を必要とするという問題があった。 In [0008] Conventionally, when employing a large zone system, low utilization efficiency of radio resources such as frequency and spreading code, small number of users can be accommodated, whereas when employing the small zone system, handover high frequency of occurrence is, there is a problem that requires excessive processing power.

【0008】この発明は上記の問題を解決すべくなされたもので、ハンドオーバ頻度を増大させることなく、多数のユーザを収容可能な無線通信基地局装置を提供することを目的とする。 [0008] The present invention has been made to solve the above problems, without increasing the handovers, and to provide a housing capable radio communication base station apparatus a number of users. また、この発明は、反射体などによるマルチパスの影響を抑制することが可能な無線通信基地局装置を提供することを目的とする。 The present invention also aims to provide a radio communication base station device capable of suppressing the effects of multipath due reflector.

【0009】 [0009]

【課題を解決するための手段】上記の目的を達成するために、この発明に係わる無線通信基地局装置は、無線回線を介して接続される通信装置を有線通信網に接続する無線通信基地局装置において、空間に第1のビームを形成して、通信装置と無線回線を介して通信を行なう複数の第1の通信手段と、この複数の第1の通信手段が形成する第1のビームよりも広いビーム幅の第2のビームを、第1のビームを包含するように形成し、通信装置と無線回線を介して通信を行なう第2の通信手段とを具備して構成するようにした。 To achieve the above object, according to the Invention The radio communication base station apparatus according to the invention, a radio communication base station that connects a communication device connected via a wireless line to a wired communication network in the apparatus, to form a first beam in the space, a plurality of first communication means for communicating via the communication device and the radio network, from the first beam the plurality of first communication means is formed the second beam is wide beamwidth, formed to include a first beam, and to constitute by comprising a second communication means for communicating via the communication device and a wireless line.

【0010】上記構成の無線通信基地局装置では、異なる幅のビームを形成する通信手段を2種備え、無線ゾーンを2種のビームを重畳して形成するようにしている。 [0010] In the radio communication base station apparatus having the above structure is in the communication means for forming a beam of different widths 2 Tanesonae, radio zones to be formed so as to overlap the two beams.
したがって、上記構成の無線通信基地局装置によれば、 Therefore, according to the radio communication base station apparatus having the above structure,
幅の狭い方のビームを形成する第1の通信手段を通じて通信装置と通信することにより、多数のユーザを収容でき、そして幅の広い方のビームを形成する第2の通信手段を通じて通信装置と通信することによりハンドオーバ頻度の増大を抑制することができる。 By communicating with the communication device through a first communication means for forming a narrow beam width, can accommodate a large number of users, and communication with the communication device through the second communication means for forming a wider beam width it is possible to suppress an increase of handovers by.

【0011】またこの発明では、第1の通信手段が通信装置との間で断続的になされる通信を行ない、第2の通信手段が通信装置との間で連続的に継続してなされる通信を行なうことを特徴とする。 [0011] In this invention, it performs communication by the first communication means is intermittently performed between the communication devices, the communication by the second communication means is made continuously to continue with the communication device and performing.

【0012】したがって、この発明によれば、ハンドオーバの影響を受けにくい断続的な通信をビーム幅の狭い第1の通信手段にて行ない、ハンドオーバの影響を受けやすい連続的に継続してなされる通信をビーム幅の広い第2の通信手段にて行なうため、ハンドオーバ頻度を増大させることなく、多数のユーザを収容することができる。 [0012] Therefore, according to the present invention performs susceptible intermittent communication the effect of handover in a narrow first communication means of the beam width, the communication to be made to continue handover susceptible continuously the order to perform over a wide second communication means of the beam width, without increasing the handovers, can accommodate a large number of users.

【0013】さらに、この発明に係わる無線通信基地局装置では、無線回線を介して接続される通信装置との間でなされる通信の種別を判定する通信種別判定手段と、 Furthermore, in the radio communication base station apparatus according to the present invention includes a communication type determination means for determining the type of communication performed between the communication apparatus connected via a radio channel,
この通信種別判定手段の判定結果に応じて、第1の通信手段と第2の通信手段のうち、いずれか一方を選択して通信装置と通信を行なう切換制御手段とを備えることを特徴とする。 According to the determination result of the communication type determination means, of the first communication means and second communication means, characterized in that it comprises a switching control means for communicating with any selected one by communication device .

【0014】したがって、この発明によれば、通信の種別に応じて異なるビーム幅の通信手段を選択的に使用して通信を行なうため、例えば1回の通信時間が短くハンドオーバの影響を受けにくい、発着信に係わる制御信号やパケットデータ通信のような断続的な通信をビーム幅の狭い第1の通信手段にて行ない、ハンドオーバの影響を受けやすい、音声による通話のような連続的に継続してなされる通信をビーム幅の広い第2の通信手段にて行なうようにすることにより、ハンドオーバ頻度を増大させることなく、多数のユーザを収容することができる。 [0014] Therefore, according to the present invention, for performing communication using selectively the communication means different beam width according to the communication type, for example, one communication time is hardly affected by the short handover, the intermittent communication such as control signals and packet data communications according to the incoming and outgoing calls performed by a narrow first communication means of the beam width, susceptible to handover, continue to continuously such as communication by speech communications to be made by the performed over a wide second communication means of the beam width, without increasing the handovers, can accommodate a large number of users.

【0015】さらにまた、この発明では、無線回線を介して接続される通信装置の移動速度が高速か否かを判定する移動速度判定手段と、この移動速度判定手段の判定結果に応じて、第1の通信手段と第2の通信手段のうち、いずれか一方を選択して通信装置と通信を行なう切換制御手段とを具備することを特徴とする。 [0015] Further, in this invention, a moving speed determining means determines the moving speed of whether high-speed communication device connected via a radio channel, in accordance with the determination result of the moving speed determining means, the of the first communication means and second communication means, characterized by comprising a switching control means for performing communication with the selected and the communication device either.

【0016】したがって、この発明によれば、通信装置の移動速度が高速か否かに応じて異なるビーム幅の通信手段を選択的に使用して通信を行なうため、例えばハンドオーバの影響を受けにくい、高速移動しない通信装置との通信にはビーム幅の狭い第1の通信手段にて行ない、ハンドオーバの影響を受けやすい、高速移動する通信装置との通信にはビーム幅の広い第2の通信手段にて行なうようにすることにより、ハンドオーバ頻度を増大させることなく、多数のユーザを収容することができる。 [0016] Therefore, according to the present invention, since the moving speed of the communication apparatus performs communication by selectively using the communication means of different beam widths depending on whether a high speed, for example, less susceptible to the handover, performed at the narrow first communication means of the beam width in communication with the communication apparatus not go fast, susceptible to handover, a wide second communication means of the beam width in communication with the communication device moving fast by so performed, without increasing the handovers, it can accommodate a large number of users.

【0017】また、この発明では、通信装置より受信した信号より、その通信品質を判定する通信品質判定手段と、この通信品質判定手段の判定結果に応じて、第1の通信手段と第2の通信手段のうち、いずれか一方を選択して通信装置と通信を行なう切換制御手段とを具備することを特徴とする。 Further, in this invention, than is received from the communication device signal, and a communication quality judging means for judging the communication quality, in accordance with the determination result of the communication quality judging means, first communication means and the second in the communication means, characterized by comprising a switching control means for performing communication with the selected and the communication device either.

【0018】したがって、この発明によれば、通信装置との通信の品質に応じて異なるビーム幅の通信手段を選択的に使用して通信を行なうため、例えばマルチパスなどにより大きな遅延が生じる場合に、ビーム幅の狭い第1の通信手段にて行なうことにより、反射体などによるマルチパスを抑制することができる。 [0018] Therefore, according to the present invention, since using the communication means of different beam widths depending on the quality of the communication with the communication device selectively communicates, for example, if a large delay due multipath occurs by performing at narrower first communication means of the beam width, it is possible to suppress the multipath due reflector.

【0099】次に、図8および図9を参照して、上記構成の無線通信基地局装置BS3の動作を以下に説明する。 [0099] Next, with reference to FIGS. 8 and 9, the operation of the radio communication base station apparatus BS3 of the structure below. まず、図8に示す移動局PS1が発信を行なう場合の動作について説明する。 First, the mobile station PS1 is the operation of the case of a call as shown in FIG.

【0100】図9に示すように、移動局PS1が発信を行なうと、これを通信リンク開設制御手段53aが、移動局PS1の位置する領域ZL1に対応する広ビーム無線部21を通じて受け付け、移動局PS1との間に通信リンクを開設する。 [0100] As shown in FIG. 9, when the mobile station PS1 performs an outgoing, this communication link establishment controller 53a is accepted through the wide beam radio unit 21 corresponding to the position region ZL1 mobile station PS1, the mobile station to establish a communication link between the PS1.

【0101】そして次に、通信品質判定手段53bが、 [0101] and then, the communication quality judgment means 53b is,
広ビーム無線部21において移動局PS1から送信信号をレイク受信する際のマルチパスの遅延スプレッドを監視する。 Monitoring the delay spread of the multipath when rake receiving a transmission signal from the mobile station PS1 in a wide beam radio unit 21.

【0102】尚、この際、当該無線通信基地局装置BS [0102] At this time, the radio communication base station apparatus BS
3には、移動局PS1より遅延量の大きいマルチパス信号が到来しないため、通信品質判定手段53bは、通信品質が劣化していないものと判定する。 3, since the larger the multipath signal delay amount from the mobile station PS1 does not arrive, the communication quality judging unit 53b judges as the communication quality is not degraded.

【0103】すると、無線部切換制御手段53cは、通信品質判定手段53bが通信品質の劣化を検出しないため、移動局PS1との間の通信を、通信リンクの開設時と同様に、広ビーム無線部21を用いて行なうよう制御する。 [0103] Then, the wireless unit switching control unit 53c, since the communication quality judging unit 53b does not detect the deterioration of the communication quality, the communication between the mobile station PS1, similarly to the time of establishment of the communication link, wide beam radio controlling to perform using parts 21.

【0104】次に、移動局PS2が発信を行なう場合の動作について説明する。 [0104] Next, the mobile station PS2 will be described operation when performing a call. 図9に示すように、移動局PS As shown in FIG. 9, the mobile station PS
2が発信を行なうと、これを通信リンク開設制御手段5 When 2 performs an outgoing communication link establishment controller 5 so
3aが、移動局PS2の位置する領域ZL1に対応する広ビーム無線部21を通じて受け付け、移動局PS2との間に通信リンクを開設する。 3a is accepted through the wide beam radio unit 21 corresponding to the position region ZL1 mobile station PS2, to establish a communication link between the mobile station PS2.

【0105】そして次に、通信品質判定手段53bが、 [0105] and then, the communication quality judgment means 53b is,
広ビーム無線部21において移動局PS2から送信信号をレイク受信する際のマルチパスの遅延スプレッドを監視する。 Monitoring the delay spread of the multipath when rake receiving a transmission signal from the mobile station PS2 in a wide beam radio unit 21.

【0106】尚、この際、当該無線通信基地局装置BS [0106] At this time, the radio communication base station apparatus BS
3には、図8に示す反射体Rの存在により移動局PS2 3, the mobile station PS2 by the presence of the reflector R shown in FIG. 8
より遅延量の大きいマルチパス信号が到来しているため、通信品質判定手段53bは、通信品質が劣化しているものと判定する。 Since the large multipath signal more delay is reached, the communication quality judging unit 53b judges as the communication quality is degraded.

【0107】すると、無線部切換制御手段53cは、通信品質判定手段53bが通信品質の劣化を検出しているため、移動局PS2との間の通信を、移動局PS2の位置する領域ZS2に対応する狭ビーム無線部12を用いて行なうよう制御する。 [0107] Then, the wireless unit switching control unit 53c, since the communication quality judging unit 53b has detected the deterioration of the communication quality, the corresponding communication between the mobile station PS2, the position area ZS2 of the mobile station PS2 controlling to perform using narrow beam radio unit 12.

【0108】以上のように、上記構成の無線通信基地局装置BS3では、通信信号に遅延スプレッドが生じていても、レイク受信によって通信品質の劣化を引き起こさないような場合には、広ビーム無線部21〜23を通じて行ない、一方、通信信号に大きな遅延スプレッドが生じレイク受信でも受信が不可能な場合には、狭ビーム無線部11〜1nを通じて行なうことにより、反射体R方向への送信を抑制するようにしている。 [0108] As described above, in the configuration of the radio communication base station apparatus BS3, when the delay spread in the communication signal even has occurred, such as not to cause degradation of communication quality by rake reception, wide beam wireless unit conducted through 21 to 23, on the other hand, when a large delay spread in the communication signal is not possible is received in rake receiver occurs, by performing through narrow beam radio unit 11 to 1n, suppress transmission to the reflector R direction It is way. すなわち、ビルなどの反射体Rにより大きな遅延スプレッドが生じる場合には、ビーム幅を狭めて通信を行なうようにしている。 That is, when a large delay spread caused by the reflector R in buildings is to perform the communication by narrowing the beam width.

【0109】したがって、上記構成の無線通信基地局装置BS3によれば、上述のような遅延スプレッドの大きいマルチパス信号による通信品質の劣化を防止することができる。 [0109] Thus, according to the radio communication base station apparatus BS3 above configuration, it is possible to prevent deterioration of communication quality due to delay spread of large multipath signals as described above.

【0110】尚、この発明は上記実施の形態に限定されるものではない。 [0110] The present invention is not limited to the above embodiment. 例えば、上記実施の形態では、マルチパス信号に起因する通信品質の劣化を防止するようにしたが、これに代わって例えば、移動局PS1〜PSjからの受信信号の信号対雑音比(CNR)を監視し、この監視結果に応じて通信に用いる無線部を切換制御するようにしてもよい。 For example, in the above embodiments, and to prevent the degradation of communication quality due to multipath signals, for example, Instead of this, the signal-to-noise ratio of the received signal from the mobile station PS1~PSj the (CNR) monitoring, the wireless unit to be used for communication in accordance with the monitoring result may be switching control.

【0111】これによれば、移動局PS1〜PSjの送信出力が伝送情報量に比べて不足する場合や、伝搬損が大きい場合に低下して、信号対雑音比が低下した際に、 [0111] According to this, or if the transmission output of the mobile station PS1~PSj is insufficient compared to the amount transmitted information, and reduced when the propagation loss is large, when the signal-to-noise ratio is reduced,
アンテナ利得の高い狭ビーム無線部11〜1nを通じて通信することにより、通信を行なうことができる。 By communicating through a high narrow beam radio unit 11~1n the antenna gain can communicate.

【0112】また、例えば、上記実施の形態では、CD [0112] Also, for example, in the above-described embodiment, CD
MA方式を例に挙げて説明したが、FDMA方式やTD The MA method has been described as an example, but, FDMA system and TD
MA方式の同様の無線通信基地局装置に適用しても効果が得られる。 Effect can be obtained by applying the same radio communication base station apparatus MA scheme. 尚、一般にFDMA方式やTDMA方式では、レイク受信は行なわないため、反射波などのマルチパスの問題は深刻であり、上述の第3の実施形態をこれらの方式に適用すれば、一層の効果を奏する。 In the general FDMA system and the TDMA system, since the rake receiver is not performed, the problem of multipath, such as a reflected wave is serious, if applied to these schemes the third embodiment described above, a further effect unlikely to.

【0113】さらに、上述では、すべての子局が移動局PS1〜PSjの場合について説明したが、子局が固定局の場合に適用することも可能である。 [0113] Further, in the above description, although all the slave station has been described for the case of the mobile station PS1~PSj, it is also possible to slave station is applied to the case of the fixed station. この場合には、 In this case,
固定子局の新設や撤去、仕様変更などに伴う、当該無線通信基地局装置のアンテナ管理の負担がなく、無線資源(周波数や拡散符号)の効率的運用を図ることができる。 New and removal of the stator station, accompanied by such specification changes, there is no burden on the antenna management of the radio communication base station apparatus, it is possible to efficiently operate radio resources (frequencies and spreading codes).

【0114】なぜなら、各固定子局に対して狭ビームアンテナを設置する場合に比べると、この発明では、広ビームアンテナを混在するようにしているため、広ビームでも不都合の生じない固定子局(例えば、送信電力に比べて通信容量が小さい子局)に対しては、広ビームによって通信を行ない、そして、大容量の通信を行なう固定子局に対しては優先的に狭ビームを割り当てて省電力化を図り、管理負担と無線資源との最適な組み合わせを得ることができる。 [0114] because each fixed as compared with the case of installing a narrow beam antenna with respect to the slave station, in this invention, a wide beam because it so the antenna mixed, wide does not cause inconvenience in the beam fixed slave station ( for example, for a slave station) communication capacity is smaller than the transmission power, performs communication by the wide beam, and, for a fixed slave station for communicating large capacity allocated preferentially narrow beam saving achieving power, it is possible to obtain an optimum combination of administrative burden and radio resources. その他、この発明の要旨を逸脱しない範囲で種々の変形を施しても同様に実施可能であることはいうまでもない。 Needless to say, the variously modified may be practiced as well without departing from the scope of the invention.

【0116】そして、通信装置との通信が断続的なものか連続的なものか、通信の種別は何か、あるいは通信装置の移動速度が高速か否かなどのハンドオーバの影響を受けやすさに関係する諸条件に応じて、通信手段を選択的に使用するようにしている。 [0116] Then, whether the communication with the communication device is intermittent ones or continuous ones, type of communication is something, or the moving speed of ease influenced by handover, such as whether high-speed communication device depending on the conditions involved, so that selective use of communication means. このため、この発明によれば、ハンドオーバ頻度を増大させることなく、多数のユーザを収容することが可能な無線通信基地局装置を提供できる。 Therefore, according to the present invention, without increasing the handovers, it can provide a radio communication base station apparatus capable of accommodating a large number of users.

【0117】また、この発明では、通信装置との通信の品質に応じて異なるビーム幅の通信手段を選択的に使用して通信を行なうため、例えばマルチパスなどにより大きな遅延が生じる場合に、ビーム幅の狭い第1の通信手段にて行なうことにより、反射体などによるマルチパスを抑制することが可能な無線通信基地局装置を提供できる。 [0117] Further, in the present invention, for performing communication using the communication means of different beam widths depending on the quality of the communication with the communication device selectively, if a large delay due multipath occurs for example, the beam by performing at narrower first communication unit width, it is possible to provide a radio communication base station device capable of suppressing a multipath due reflector.
