【発明の属する技術分野】本発明は、複数の無線ゾーンでサービスエリアを構成する移動通信方式において、無線チャネルを必要に応じてダイナミックに割り当てる無線チャネル割当方法に関する。 The present invention relates, in the mobile communication system constituting a service area with a plurality of radio zones, a radio channel assignment method for assigning dynamically as required radio channel.

【0002】 [0002]

【従来の技術】複数の無線ゾーンでサービスエリアを覆う移動通信システムにおいて、従来のダイナミックチャネル割当方法は、各無線ゾーンに共通使用可能な複数の無線チャネルを割り当て、移動局からの無線通信チャネル割り当て要求の都度、これから割り当てを行おうとする無線通信チャネルが他の無線ゾーンで使用されているか否かを、無線通信チャネルの干渉波レベル測定によって検索し、無線通信チャネルの通信路としての所要品質を満足しているかを判断して、この所要品質を満足していると判断した場合に、当該無線通信チャネルを割り当てていた。 BACKGROUND ART In a mobile communication system for covering a plurality of service areas in a wireless zone, a conventional dynamic channel allocation method allocates the plurality of wireless channels available common use for each radio zone, the radio communication channel assignment from the mobile station each request, whether the wireless communication channel is being used by another radio zone to be performed from now assigned to search by interference wave level measurement of radio communication channels, the required quality of the communication channel of the wireless communication channel to determine whether the satisfied, when determining that satisfies the required quality, and assigns the wireless communication channel. このとき、これから行おうとする音声、データ等の無線通信チャネルの通信種別とは無関係に一律に一定の所要品質で無線通信チャネルの割り当てを行っている。 At this time, and it assigns radio communication channel at the required quality constant independently of uniformly to the future Gyoo it to voice, communication type of the radio communication channel data.

【0003】 [0003]

【発明が解決しようとする課題】従来の移動通信システムにおいては、移動局の移動または車両の移動等の無線伝搬路の変化により、通信中に干渉による品質劣化が生じた場合、品質劣化を回避するために通信チャネル切り替え等の干渉回避機能を具備している。 In the [0008] conventional mobile communication system, changes in the radio propagation path such as movement of the moving vehicle or mobile station, when the quality deterioration due to interference during communication occurs, avoiding quality deterioration and it includes an interference avoidance function such as communication channel switch to. しかし、この制御においては、通信チャネル切り替えを伴うため、通信を一時的にでも断状態にせざるを得ない。 However, in this control, since with a communication channel switching, forced to cross state even communication temporarily the. このことは、 This means that,
特に、データ通信のサービスにおいては、伝送データの欠損を引き起こし、欠損データの再送制御のための制御負荷の増加、データ伝送スループットの低下という問題を招く結果となる。 In particular, in the data communication services, causing a loss of transmission data, increase in the control load for retransmission control of missing data, resulting in causing a problem of reduced data transmission throughput.

【0004】この対策として、無線通信チャネルの所要品質を高く設定しておき、ある程度の干渉波のレベル増加があった場合でも、所要品質を下回ることがないような無線通信チャネルを割り当てることが考えられる。 [0004] As a countermeasure, previously set high required quality of the radio communication channels, considered to allocate a wireless communication channel, such as not to fall below any, required quality when there is increased levels of some interference waves It is. しかし、この方法では、無線通信チャネルの利用効率が低下し、所要システムチャネル数が増大する。 However, in this method, it reduces the utilization efficiency of the wireless communication channel, the required system the number of channels increases. これは、音声通信のようにある程度の無線通信チャネルの切り替えが許容されている無線通信チャネル、つまり、データ通信を行う無線通信チャネルよりも所要品質が低い無線通信チャネルに対しても通信内容には無関係に一律一定の高い所要品質で無線通信チャネルの割り当てを行うために、通信チャネルの利用効率が低下するためである。 This is somewhat of a wireless communication channel a wireless communication channel switching is acceptable as voice communication, i.e., the communication content even to wireless communication channel required quality is lower than the radio communication channel for performing data communication in order to perform allocation of radio communication channels independent uniform constant high required quality, utilization efficiency of the communication channel is lowered.

【0005】本発明は、このような従来技術の問題を解決するもので、無線通信チャネルの周波数利用効率の高い移動通信システムの無線通信チャネル割当方法を提供することを目的とする。 [0005] The present invention is intended to solve the problems of the prior art, and an object thereof is to provide a radio communication channel assignment method of high mobile communication system frequency utilization efficiency of the wireless communication channel. また、データ通信等においては、伝送データの欠損を引き起こすチャネル切り替え制御の発生確率が低下し、データの再送制御のための制御負荷を低減し、データ伝送スループットが向上できる無線チャネル割当方法を提供することを目的とする。 Further, in the data communication or the like, the probability of the channel switch control that causes loss of transmission data is reduced, reducing the control load for retransmission control of data and provides a radio channel allocation method capable of improving data transmission throughput and an object thereof.

【課題を解決するための手段】本発明は、移動通信システムにおいて、移動局が無線基地局に対して発する無線通信チャネルの通信種別の情報に基づいて、各通信種別ごとの所要品質を満足する無線通信チャネルを割り当てることを特徴とする。 Means for Solving the Problems The present invention, in a mobile communication system, the mobile station based on the information of the communication type of the radio communication channel that emits the radio base station satisfies the required quality for each communication type and allocating the radio communication channel.

【0007】本発明は、無線基地局と移動局との間で無線回線を介して双方向の通信が行われ、前記移動局からの通信接続要求が発生したときに、通信路として所要品質を満足する無線通信チャネルを選択して割り当てる無線通信チャネル割当方法において、前記所要品質として希望波対干渉波電力比を用いる場合、前記無線基地局は、前記移動局からの通信接続要求があったときに、前記移動局からの制御信号に基づいて前記移動局が要求した通信種別を判断するとともに前記移動局からの通信接続要求の制御信号の受信レベルを測定し、この制御信号の受信レベルと各無線通信チャネルにおける干渉波受信レベルとに基づいて各無線通信チャネルの希望波対干渉波電力比を算出し、算出された希望波対干渉波電力比の値が前記移動局から [0007] The present invention, bidirectional communication is performed through a radio line between a radio base station and a mobile station, when the communication connection request from the mobile station is generated, the required quality as a communication channel in the wireless communication channel assignment method for assigning select a satisfactory radio communication channel, when using the signal to interference ratio as the required quality, the radio base station, when a communication connection request from the mobile station in the receiving level of the control signal of communication connection request from the mobile station as well as determine the communication type in which the mobile station has requested measured based on a control signal from the mobile station, each and receiving level of the control signal based on the interference wave receiving level in a radio communication channel to calculate the signal to interference power ratio of each radio communication channel, the value of the calculated signal to interference ratio from said mobile station 信接続要求のあった通信種別に対応した所要品質を満足するとき、当該無線通信チャネルを移動局に割り当てる。 When satisfying the required quality corresponding to the communication type for which the signal connection request, assigns the wireless communication channel to the mobile station.

【0008】本発明では、移動通信システムにおいて、 [0008] In the present invention, in a mobile communication system,
移動局が無線基地局に対して要求するデータ通信、音声、Fax等の通信種別に応じて、その所要品質が定められている。 Data communication mobile station requests the radio base station, speech, according to the communication type Fax such, the required quality is determined. 移動局が通信接続要求を行うと、無線基地局は、移動局の接続要求する通信種別に応じてその所要品質を満足する通信路を検索して無線通信チャネルを割り当てる。 When the mobile station performs communication connection request, the radio base station assigns a radio communication channel by searching the channel that satisfies the required quality depending on the communication type to the connection request of the mobile station. これにより、通信種別に一律に所要品質を設定して無線通信チャネルを割り当てる方法に比べて無線通信チャネルの周波数利用効率を高めることができ、また、データ通信のサービスにおいては、伝送データの欠損を引き起こすチャネル切り替え制御の発生確率が低下するので、データ再送制御のための制御の負荷を低減でき、データ伝送スループットを向上することができる。 Thus, compared with a method of assigning radio communication channels to set the required quality uniformly on the communication type can improve the frequency utilization efficiency of the wireless communication channel, also in the data communication service, the loss of transmitted data since the probability of the channel switch control to cause drops can reduce the load of the control for data retransmission control, it is possible to improve the data transmission throughput.

【0011】図2は、無線基地局の構成を示すものであり、アンテナ20と、変復調機能を含む送受信部(TR [0011] FIG. 2 shows a configuration of a radio base station, an antenna 20, transceiver including a modem function (TR

【0012】図3は、本発明が実施される移動通信システムにおける呼接続シーケンスを示すものである。 [0012] Figure 3 shows a call connection sequence in a mobile communication system to which the present invention is implemented. すなわち、通信を行うために移動局から呼接続要求が発生すると、移動局が無線基地局に対して制御チャネル上で、 That is, when the call connection request is generated from the mobile station to communicate, on the control channel the mobile station to a radio base station,
通信チャネル要求信号を送出する。 It sends a communication channel request signal. この通信チャネル要求信号を無線基地局が受信すると、無線通信チャネル割当アルゴリズムにしたがって、所要品質を満足する無線通信チャネルを検索し、所要品質を満足する無線通信チャネルが検索された場合、移動局に対して無線基地局は、通信チャネル割当信号によって、無線通信チャネルの割り当てを行う。 When the communication channel request signal radio base station receives, according to a wireless communication channel assignment algorithm searches the wireless communication channel which satisfies the required quality, when the wireless communication channel which satisfies the required quality has been searched, the mobile station the radio base station for, by a communication channel assignment signal, performs allocation of radio communication channels.

【0013】ここにおいて、本発明の特徴とする点は、 [0013] In this case, that is a feature of the present invention,
無線基地局4は、移動局5からの通信接続要求があったときに、移動局5からの制御信号に基づいて移動局5が要求した通信種別を判断するとともに移動局5からの通信接続要求の制御信号の受信レベルを測定し、この制御信号の受信レベルと各無線通信チャネルにおける干渉波受信レベルとに基づいて各無線通信チャネルの希望波対干渉波電力比を算出し、算出された希望波対干渉波電力比の値が前記移動局から通信接続要求のあった通信種別に対応した所要品質を満足するとき、当該無線通信チャネルを移動局5に割り当てることにある。 The radio base station 4, when there is a communication connection request from the mobile station 5, a communication connection request from the mobile station 5 with the mobile station 5 determines communication type requested based on the control signal from the mobile station 5 the reception level of the control signal is measured in hope this calculates the signal to interference power ratio of each radio communication channel based on the reception level of the control signal and the interference wave receiving level in each radio communication channel, which is calculated when the value of the wave interference power ratio satisfies the required quality corresponding to a communication type of the communication connection request from the mobile station is to assign the radio communication channel to the mobile station 5.

【0014】まず、本実施の形態では、無線基地局4内にある記憶部25に通信種別ごとに所要品質値を記憶している。 [0014] First, in the present embodiment, it stores the required quality value for each communication type in the storage unit 25 in the radio base station 4. 図4は、この通信種別ごとの所要品質値の記憶状態を示したものであり、通信種別A1は、所要品質値C1、通信種別A2は、所要品質値C2というように、 4, this is limited to showing a storage state of the required quality value for each communication type, communication type A1 is required quality value C1, communication type A2, as that required quality value C2,
通信種別Amにまで、通信種別ごとに無線通信路の所要品質が記憶されている。 Until the communication type Am, required quality of wireless channel is stored for each communication type.

【0015】次に、本発明の実施の形態における無線通信チャネルの割り当て動作を説明する。 [0015] Next, the allocation operation of the wireless communication channel in the embodiment of the present invention.

【0016】いま、移動局5が無線基地局4に対して、 [0016] Now, the mobile station 5 to the radio base station 4,
無線通信チャネルの要求を行うことについて説明する。 It described that makes a request for wireless communication channels.
移動局5が無線基地局4に対して、無線通信チャネルの要求を行うために、移動局5より無線制御チャネル上で、リンクチャネル確立要求信号によって、無線基地局に通信チャネル要求信号を送信する。 Mobile station 5 to the wireless base station 4, in order to make a request of the radio communication channel on the radio control channel from the mobile station 5, the link channel establishment request signal, transmits a communication channel request signal to the radio base station . この信号には、無線通信チャネルの通信種別情報も付随しており、無線基地局4は、当該信号の受信レベルを受信レベル測定部2 This signal, the communication type information of the wireless communication channels is also accompanied, wireless base station 4, the reception level measuring unit 2 a reception level of the signal
3で測定するとともに、処理部26で信号を解析し、当該移動局5より要求された無線通信チャネルの通信種別を判読する。 With measured at 3, it analyzes the signal processing unit 26, to decipher the communication type of the requested wireless communication channel from the mobile station 5.

【0017】図9は、この制御チャネル上の信号コーディングの例を示したものであり、メッセージ種別、通信種別、移動局番号を含んだ信号形態である。 [0017] Figure 9 is a drawing showing an example of a signal coding on the control channel, message type, communication type, a signal form that includes a mobile station number. 図10は、 Figure 10,
この信号コーディングの意味の例を示すものである。 It illustrates an example of the meaning of the signal coding. 通信種別としては、音声通信、データ通信、FAX等が設定されている。 The communication type, voice communication, data communication, FAX or the like is set. これにより、メッセージ種別4ビットがビットフォーマット“0001”であれば通信チャネル要求の信号であることが分かり、それに続く通信種別4 Thus, we notice that the message type 4 bit is a signal of the communication channel request if the bit format "0001", the communication type followed by 4
ビットが“0001”であれば、“音声”であることが判別できる。 If the bit is "0001", it can be determined to be a "voice".

【0018】処理部26は、あらかじめ無線基地局4内にある記憶部25に記憶されている通信種別ごとの所要品質値を読み出し、移動局から今回要求された無線通信の通信種別に対応した所要品質値Cを求める。 The processing unit 26 in advance reads the required quality value for each communication type stored in the storage unit 25 in the radio base station 4, required for the communication type of the currently requested radio communication from the mobile station determine the quality value C. 例えば、 For example,
要求された無線通信の通信種別がA1であった場合、所要品質値はC1であると求まる。 If the communication type of the requested radio communication was A1, the required quality value is determined to be C1. ここで、所要品質値としては、例えば所要CIR(希望波対干渉波電力比)を用いる。 Here, the required quality value is, eg, desired CIR (signal to interference ratio).

【0019】いま、移動局5から要求されている無線通信の通信種別がA1であり、当該無線基地局で受信された通信チャネル要求信号の受信レベルがBであったとする。 [0019] Now, the communication type of the radio communication being requested from the mobile station 5 is A1, the reception level of the communication channel request signal received by the radio base station is assumed to be B. 図5は、無線基地局4で測定された各無線通信チャネルの干渉波受信レベルおよび通信チャネル要求信号の受信レベルB(希望波受信レベル)より算出されたCI 5, was calculated from the reception level B (desired wave reception level) of the interference wave receiving level and the communication channel request signals of each radio communication channel measured in the radio base station 4 CI
Rの様子を示すものである。 It shows the state of R. CIRは、CIR=(希望波受信レベルB)/(干渉波受信レベル)により算出される。 CIR is calculated by CIR = (desired wave reception level B) / (interference wave reception level). このCIRは各無線通信チャネルごとに算出される。 The CIR is calculated for each radio communication channel.

【0020】各無線通信チャネルの干渉波受信レベルの測定は、無線基地局が移動局から無線通信チャネルの要求を受けた時点で行ってもよいし、また常時継続的に行ってもよい。 [0020] Measurement of the interference wave reception level of each radio communication channel may be performed at the time the wireless base station has received a request for a wireless communication channel from a mobile station, or may be performed at all times continuously. 無線基地局が継続的に無線通信チャネルの状態監視を行うときに併せて干渉波受信レベルの測定を行うようにしていればよいため、特段の測定ステップを必要としない利点がある。 Since it is sufficient to perform the measurement of the interference wave receiving level together when the wireless base station continually monitors the status of the wireless communication channel, there is an advantage that does not require special measurement step.

【0021】無線基地局4内の処理部26は、各無線通信チャネル(1〜n)のCIRの計算を行い、先に求められた通信種別Aの所要品質値Cを越えている無線通信チャネルを検索する。 The processing unit 26 of the radio base station 4, each radio performs the computation of the CIR of the communication channel (1 to n), a radio communication channel exceeds the required quality value C of a communication type A obtained previously Search for. 所要品質値C1を越えている無線通信チャネルが検索されれば、当該無線通信チャネルを通信種別A1で通信チャネルを要求した移動局5に割り当てる。 If the wireless communication channel is retrieved that exceeds the required quality value C1, allocated to the mobile station 5 that has requested a communication channel the wireless communication channel for a communication type A1. なお、当該無線基地局4にすでに通信チャネルとして使用している通信チャネルは検索対象外である。 The communication channel used as already communication channel to the radio base station 4 is outside the search target.

【0022】図6はこの無線通信チャネル割り当て動作を説明するフローチャートである。 [0022] FIG 6 is a flowchart for explaining the wireless communication channel allocation operation. 無線基地局は、通信チャネルを1から順に使用中の通信チャネルを除いて、 The radio base station, with the exception of the communication channel in use a communications channel in order from 1,
通信種別に対応する所要品質値を満足するか否かを検索して、所要品質値を満足する通信チャネルKが見つかればそれを割り当て、システムに割り当てられている通信チャネルに通信種別に対応する所要品質を満足する通信チャネルがないときは、その旨を移動局に通知する。 Searching for whether to satisfy the required quality value corresponding to the communication type, assigns it if found communication channel K which satisfies the required quality value, corresponding to the communication type in the communication channel assigned to the system required when there is no communication channel which satisfies quality, notifies the mobile station.

【0023】図7に、本発明の効果を確認するためのシミュレーションの条件を説明するものである。 [0023] FIG. 7, illustrates the simulation of conditions for confirming the effect of the present invention. ここで、 here,
所要品質値のCIRとして、データ通信呼に「30d As the CIR of the required quality value, the data communication call "30d

【発明の効果】以上のように、本発明によると、無線通信チャネルの通信種別ごとの所要品質に基づいて無線通信チャネル割り当てを行うため、無線通信チャネルの周波数利用効率の高い移動通信システムを実現できる。 As is evident from the foregoing description, according to the present invention, for performing wireless communication channel assignment based on the required quality for each communication type of the radio communication channels, achieve high mobile communication system frequency utilization efficiency of the wireless communication channel it can. また、データ通信等の所要品質の高い無線通信チャネルが必要となる通信においては、所要品質の高い無線通信チャネルを割り当てるため、伝送データの欠損を引き起こすチャネル切り替え制御の発生確率が低下し、データの再送制御のための制御負荷が低減し、データ伝送スループットを向上できる効果がある。 In the communication of required quality with high wireless communication channel is required for data communication or the like, to assign a high required quality wireless communication channel, it reduces the probability of the channel switching control which causes loss of transmission data, the data control load is reduced for the retransmission control, there is an effect capable of improving data transmission throughput.
