チヤネル制御装置およびチャネル制御方法  Channel control device and channel control method
本発明は、 w L Lシステムの基地局制御局または無線基地局においてチャネル 制御を行うチャネル制御装置と、 そのチャネル制御装置において実行されるチヤ ネル制御方法とに関する。 The present invention relates to a channel control device for performing channel control in a base station control station or a radio base station of a wLL system, and a channel control method executed in the channel control device.
近年、 移動通信システムを構成する機器は、 製造者の競争および技術開発の下 で価格性能比に併せて、 付加価値が高められつつある。 In recent years, the added value of the equipment that composes the mobile communication system has been increasing along with the price-performance ratio due to the competition of manufacturers and technological development.
また、 このような機器は、 チャネル制御や加入者情報の管理にかかわる処理の 形態が変更されることによって、 固定の加入者に対する電話系およびデ一夕系の 通信サービスの提供にも適用され得るために、 加入者線が無線伝送路で代替され ることによって、 安価に確度高く、 かつ迅速に多くの加入者を収容可能である w In addition, such devices can be applied to the provision of telephone and overnight communication services to fixed subscribers by changing the mode of processing related to channel control and management of subscriber information. Therefore, by replacing the subscriber line with a wireless transmission line, it is possible to accommodate a large number of subscribers at low cost, with high accuracy, and quickly.
LL (Wireless local Loop)システムに積極的に転用されている。 Actively diverted to the LL (Wireless local Loop) system.
図 6は、 WLLシステムの構成例を示す図である。  FIG. 6 is a diagram showing a configuration example of the WLL system.
図において、 無線基地局 41-1-41-n によって形成される無線ゾーン 42-1 〜42-nには加入者装置 (SU) 43-1〜43-nが設置され、 これらの無線基地 局 41-1〜41-nは、 それそれ通信リンク 44-:!〜 44-nを介して基地局制御装 置 45に接続される。 基地局制御装置 45は、 保守監視装置 46に接続され、 か つ加入者線交換機 47を介して公衆電話網 48に接続される。  In the figure, subscriber units (SU) 43-1 to 43-n are installed in wireless zones 42-1 to 42-n formed by the wireless base stations 41-1-41-n. 41-1 to 41-n are connected to the base station controller 45 via communication links 44- :! to 44-n, respectively. The base station control unit 45 is connected to a maintenance monitoring unit 46, and is connected to a public telephone network 48 via a local exchange 47.
なお、 以下、 加入者装置 43-:!〜 43-n に共通の事項と、 無線基地局 41-1〜 41-nに共通の事項とについては、 添え番号 「1」 〜 「n」 の何れかを意味する 添え文字 「c」 を符号 「43」 、 「41」 にそれぞれ付加して記述する。  Hereinafter, items common to the subscriber units 43- :! to 43-n and items common to the radio base stations 41-1 to 41-n will be described with reference to any one of the appendix numbers “1” to “n”. The suffix “c” is added to the signs “43” and “41”, respectively.
このような構成の WLLシステムでは、 加入者装置 43-cは、 既述の移動通信 システムの端末が有する機能の全てを具備し、 始動時には、 規定のチャネル構成 およびゾーン構成に適合したチャネル制御の下で 「自局が位置する無線ゾーン 4 1 -cの識別」 と、 「その無線ゾーン 4 1 -cが属する位置登録エリアに対する位置 登録」 とを行った後に、 発信および着信が可能な 「待ち受け状態」 に移行する。 基地局制御装置 4 5は、 このような位置登録を達成するチャネル制御の手順に 基づいて、 該当する加入者装置 4 3 -cを識別し、 その加入者装置 4 3 -cが在圏す る無線ゾーンと、 この加入者装置 4 3 -cに対する通信サービスの提供に際して参 照されるべき種々の属性 (サービスオーダを含む。 ) とを一元的に管理し、 かつ' 適宜更新する。 In the WLL system having such a configuration, the subscriber unit 43-c has all the functions of the terminal of the mobile communication system described above, and at the time of startup, performs channel control conforming to the prescribed channel configuration and zone configuration. Under "Wireless zone 4 where your station is located After performing “identification of 1-c” and “location registration for the location registration area to which the wireless zone 41-c belongs”, the mobile terminal shifts to the “standby state” where transmission and reception are possible. The base station controller 45 identifies the corresponding subscriber unit 43-c based on the channel control procedure for achieving such location registration, and the subscriber unit 43-c is located. The wireless zone and various attributes (including the service order) to be referred to when providing the communication service to the subscriber unit 43-c are centrally managed and updated as appropriate.
したがって、 加入者装置 4 3 -cと無線基地局 4 1 -cとの間には、 無線伝送路で 代替された加入者線が安価に速やかに形成され、 この加入者装置 4 3 -cには、 移 動通信用に標準化され、 高い付加価値を有する端末装置が転用されることによつ て、 固定の端末装置より安価に多様な通信サービスが提供される。  Therefore, a subscriber line replaced by a wireless transmission line is quickly and inexpensively formed between the subscriber unit 43-c and the radio base station 41-c. Is standardized for mobile communications, and by diverting terminal devices with high added value, various communication services are provided at a lower cost than fixed terminal devices.
なお、 上述した W L Lシステムでは、 無線ゾーン 4 2 -1〜4 2 -nは、 それそれ 無線基地局 4 1 -:!〜 4 1 -nによって単一のォムニゾーンとして形成されている。  In the WLL system described above, the wireless zones 4 2 -1 to 4 2 -n are each formed as a single omni zone by the wireless base stations 4 1-:! to 4 1 -n.
しかし、 これらの無線ゾーン 4 2 -:!〜 4 2 -nは、 何れも複数のセクタゾーンの 集合として構成されてもよい。  However, any of these wireless zones 42- :! to 42-n may be configured as a set of a plurality of sector zones.
ところで、 上述した従来例では、 加入者装置 4 3 -cは、 既述の移動通信システ ム用の端末装置の転用によって実現されるために、 例えば、 ビルの建築等に起因 してこの加入者装置 4 3 -cと無線基地局 4 1 -cとの間におけ.る無線伝送の伝送品 質が著しく劣化した場合には、 無線ゾーン 4 2 -c以外の無線ゾーンを介して基地 局制御装置 4 5にアクセスし得る。  By the way, in the above-described conventional example, the subscriber device 43-c is realized by diverting the terminal device for the mobile communication system described above. If the transmission quality of the wireless transmission between the device 43-c and the wireless base station 41-c is significantly degraded, the base station is controlled via a wireless zone other than the wireless zone 42-c. Access to devices 45.
また、 基地局制御装置 4 5によって行われる加入者情報の管理の下でこのよう なアクセスが規制される場合には、 加入者装置 4 3 -cは、 その加入者装置 4 3 -c の管理にかかわる加入者情報その他の局情報が更新されるまで、 通信サービスの 提供を受けることはできない。  In the case where such access is regulated under the management of the subscriber information performed by the base station controller 45, the subscriber unit 43-c manages the subscriber unit 43-c. Until the subscriber information and other station information related to are updated, communication services cannot be provided.
さらに、 この局情報が更新されるためには、 加入者装置 4 3 -cが位置する地点 に形成されている無線ゾーンの内、 好適な無線ゾーンがフィ一ルドテスト等に基 づいて確定されなければならなかった。  Furthermore, in order to update this station information, a suitable wireless zone among the wireless zones formed at the point where the subscriber unit 43-c is located must be determined based on a field test or the like. I had to.
また、 このような局情報が更新されても、 加入者装置 4 3 -cに備えられたアン テナの主ローブの方向が上述した好適な無線ゾーンを形成する無線基地局の方向 に変更されなければ、 その加入者装置 4 3 -cは、 良好な伝送品質で通信サービス の提供を受けることができるとは限らなかった。 Also, even if such station information is updated, the direction of the main lobe of the antenna provided in the subscriber unit 43-c is the direction of the radio base station forming the preferable radio zone described above. If not changed, the subscriber unit 43-c could not always be provided with a communication service with good transmission quality.
しかし、 上述した伝送品質の劣化は、 W L Lシステムが稼働する期間が長いほ ど発生する可能性が高く、 かつ突発的に、 あるいは経年的にも発生し得る。  However, the above-described degradation of transmission quality is more likely to occur as the period during which the WLL system operates is longer, and may occur suddenly or over time.
さらに、 加入者装置 4 3 -cは、 該当する加入者が地理的に隔たった場所へ転居 し、 あるいは移動した場合であっても、 下記の条件が成立する限り、 何れかの無 線ゾーンにおいて待ち受け状態となり、 その無線ゾーンを介して発信又は着信呼 に対する応答を行い、通話信号の送受に供されるべき無線チャネルを捕捉し得る。 • 加入者装置 4 3 -cに駆動電力が供給される。  In addition, even if the subscriber moves or moves to a geographically separated location, the subscriber unit 43-c will be able to operate in any of the radio zones as long as the following conditions are satisfied. The mobile station enters a standby state, responds to an outgoing or incoming call through the wireless zone, and can acquire a wireless channel to be used for transmitting and receiving a call signal. • Drive power is supplied to the subscriber unit 43-c.
· 空中線系が維持され、 あるいは何らかのアンテナで代替される。  · Antenna system is maintained or replaced by some antenna.
• 加入者装置 4 3 -cが位置する地点に、 周波数配置、 チャネル構成、 多元接続 方式、 変復調方式その他の面で互換性を満たす無線ゾーンが形成され、 その無線 ゾーンに対するアクセスを妨げる要因(例えば、輻輳に適応するトラヒック制御) がない。  • A wireless zone that satisfies compatibility in terms of frequency allocation, channel configuration, multiple access method, modulation and demodulation method, etc. is formed at the location where the subscriber unit 43-c is located, and factors that hinder access to that wireless zone (eg, Traffic control to adapt to congestion).
しかし、 このような無線チャネルの捕捉が何ら規制されることなく許容される 場合には、 例えば、 下記の問題が発生する。  However, if the capture of such a wireless channel is permitted without any restrictions, for example, the following problem occurs.
• 移動通信サービスの提供者と W L Lシステムを介する固定通信サ一ビスとの 提供者の間における営業やサービスの形態の相違が不明確となる。  • It is unclear how sales and service types differ between mobile communication service providers and fixed-line communication service providers via the WLL system.
• 加入者装置 4 3 -cを介して実質的な移動通信サービスが提供され得るために、 本来の移動通信サ一ビスの加入者との間に不公正な料金の格差が生じる。 • Since substantial mobile communication services can be provided via the subscriber unit 43-c, there will be an unfair disparity in rates with the subscribers of the original mobile communication service.
• 移動通信システムの加入者の増加が不当に阻害される。  • The increase in mobile communication system subscribers is unduly hindered.
- 発信元や着信先である加入者装置 4 3 -cの位置に適応した料金の設定の基準 が損なわれ、 移動通信サービスと固定通信サービスとの間における料金体系の相 違が維持され難くなる。  -The standard for setting fees that is appropriate for the location of the subscriber device 4 3 -c, which is the source or destination, is impaired, making it difficult to maintain the difference in the fee structure between the mobile communication service and the fixed communication service .
· 無線ゾーン毎のトラヒックの分布が不適正に偏る可能性がある。 昍の闘示  · The distribution of traffic in each wireless zone may be improperly biased.闘

The control unit 11 performs channel control related to the subordinate wireless zone. The positioning means 12 obtains the position of each wireless terminal accessed via this wireless zone. The control means 11 is determined by the positioning means 12 and is transmitted via the above-mentioned wireless zone. When the deviation or rate of change of the position of the wireless terminal that has been accessed exceeds the specified threshold, the channel control for that wireless terminal is restricted.
すなわち、 生起した呼の呼設定、 あるいは位置登録やハンドオフの過程で上述 した無線ゾーンを介してアクセスした無線端末にかかわるチャネル制御は、 その 無線端末が予め限定された地点以外に移設され、 あるいは車両等の移動体に搭載 されることにより移動した場合には、 正常には行われない。  In other words, the call control of the generated call, or the channel control related to the wireless terminal accessed via the wireless zone in the process of location registration and handoff in the process of the above-mentioned call, is performed by moving the wireless terminal to a location other than the previously defined point, or If it moves by being mounted on a mobile object such as, it will not be performed normally.
したがって、 これらの無線端末は、 適正な地点に設置され、 かつ移動すること なく運用される場合に限って、 通信サービスが提供される。  Therefore, communication services are provided only when these wireless terminals are installed at appropriate locations and operated without moving.
本発明にかかわる第二のチャネル制御装置の原理は、 下記の通りである。 測位手段 1 2は、 上述した無線ゾーンを介してアクセスした個々の無線端末の 無線基地局を基準とした方位と距離との双方もしくは何れか一方として、 その無 線端末の位置を求める。  The principle of the second channel control device according to the present invention is as follows. The positioning means 12 obtains the position of each wireless terminal accessed via the above-described wireless zone as the azimuth and / or distance of the wireless base station with reference to the wireless base station.
このような方位や距離は、 一般に、 位置を求める演算に比べて、 少ない処理量 で簡便に、 かつ高速に求められる。  Such azimuths and distances can generally be obtained simply and at high speed with a small amount of processing compared to the calculation for obtaining the position.
したがって、 上述した方位や距離が並行して求められるべき無線端末の数が大 きい場合であっても、 これらの無線端末が移動したことと、 移動しつつあること とが効率的に確度高く識別され、 その結果に応じてチヤネル制御の規制が適正に 行われる。  Therefore, even when the number of wireless terminals whose azimuths and distances are to be obtained in parallel is large, it is possible to efficiently and accurately identify that these wireless terminals have moved and that they are moving. According to the result, the channel control is properly regulated.
本発明にかかわる第三のチャネル制御装置の原理は、 下記の通りである。 測位手段 1 2は、 上述した無線ゾーンを形成する単一の無線基地局に無線端末 から到来した受信波に規定の航法を適用することによって、 その無線端末の位置 を求める。  The principle of the third channel control device according to the present invention is as follows. The positioning means 12 obtains the position of the wireless terminal by applying prescribed navigation to the received wave arriving from the wireless terminal to the single wireless base station forming the wireless zone described above.
すなわち、 無線端末の測位は、 複数の無線基地局が連係することなく達成され o  That is, the positioning of the wireless terminal is achieved without the cooperation of a plurality of wireless base stations.
したがって、 無線端末の測位に伴うチヤネル制御の遅延が最小限度に抑えられ る。  Therefore, the delay of the channel control due to the positioning of the wireless terminal can be minimized.
本発明にかかわる第四のチャネル制御装置の原理は、 下記の通りである。 測位手段 1 2は、 上述した無線ゾーンとその無線ゾーン以外の無線ゾーンとを 形成する無線基地局に無線端 ¾から到来した受信波に規定の航法を適用すること によって、 その無線端末の位置を求める。 The principle of the fourth channel control device according to the present invention is as follows. The positioning means 12 is to apply a prescribed navigation to a received wave arriving from a wireless terminal to a wireless base station forming the wireless zone described above and a wireless zone other than the wireless zone. To determine the location of the wireless terminal.
すなわち、 無線端末の測位は、 その無線端末が位置し得る無線ゾーンが広い場 合であっても、 精度よく達成される。  In other words, positioning of the wireless terminal can be accurately achieved even when the wireless zone where the wireless terminal can be located is wide.
したがって、 多様なゾーン構成に対する柔軟な適応が可能となる。  Therefore, flexible adaptation to various zone configurations becomes possible.
本発明にかかわる第五のチャネル制御装置の原理は、 下記の通りである。  The principle of the fifth channel control device according to the present invention is as follows.
測位手段 1 2は、 上述した無線端末によって自立的に求められ、 その無線端末 によって通知された情報を処理することによって、この無線端末の位置を求める。 すなわち、 無線端末の測位は、 その無線端末に備えられ、 かつ所定の電波航法 や自立航法に基づいて自局の位置を自立的に求める手段との機能分散の下で、 負 荷が無用に増加することなく確実に達成される。  The positioning means 12 obtains the position of the wireless terminal by processing the information autonomously obtained by the above-described wireless terminal and notified by the wireless terminal. In other words, the load on the wireless terminal is unnecessarily increased under the function dispersion of the function provided by the wireless terminal and the means for independently obtaining the position of the own station based on the predetermined radio navigation or the independent navigation. Without fail.
したがって、 無線端末との連係と、 その連係によって達成される分散処理との 下で、 構成の簡略化に併せて、 信頼性の向上が図られる。  Therefore, the reliability is improved along with the simplification of the configuration under the linkage with the wireless terminal and the distributed processing achieved by the linkage.
本発明にかかわる第六のチャネル制御装置の原理は、 下記の通りである。  The principle of the sixth channel control device according to the present invention is as follows.
測位手段 1 2は、 制御手段 1 1によって行われるチャネル制御の手順に基づい て無線端末から到来した受信波に規定の無線航法に基づく処理を施すことによつ て、 その無線端末の位置を求める。  The positioning means 12 obtains the position of the wireless terminal by performing processing based on a prescribed wireless navigation on a received wave arriving from the wireless terminal based on the channel control procedure performed by the control means 11 .
すなわち、 無線端末の測位は、 チャネル制御の手順に基づいて本来的にその無 線端末から到来する受信波のみに上述した処理が施されることによって行われる c したがって、 このような測位がチヤネル制御の手順が変更されることなく達成 され、 かつ個々の無線ゾーンにおけるトラヒックの多様な分布に対する柔軟な適 応が担保される。 That is, the positioning of the wireless terminal, c is carried out by processes described above only in the reception waves arriving inherently from its free line terminal based on the procedure of the channel control is performed Accordingly, such positioning is channel control This procedure is achieved without change, and flexible adaptation to various distributions of traffic in individual wireless zones is ensured.
本発明にかかわる第七のチャネル制御装置の原理は、 下記の通りである。  The principle of the seventh channel control device according to the present invention is as follows.
測位手段 1 2は、 制御手段 1 1によって行われるチャネル制御の過程で無線端 末から通知された情報に規定の処理を施すことによって、 その無線端末の位置を 求める。  The positioning means 12 obtains the position of the wireless terminal by performing prescribed processing on the information notified from the wireless terminal in the course of the channel control performed by the control means 11.
すなわち、 無線端末の測位は、 その無線端末に備えられ、 かつ所定の電波航法 や自立航法に基づいて自局の位置を自立的に求める手段による負荷分散と、 チヤ ネル制御の手順に基づいてこの無線端末から受信されるべき情報の余剰のフィ一 ルドの活用との下で、 本発明にかかわるチャネル制御装置の負荷が無用に増加す ることなく確実に達成される。 That is, the positioning of the wireless terminal is performed based on the load distribution by means provided for the wireless terminal and autonomously obtaining the position of the own station based on predetermined radio navigation or self-contained navigation, and based on the channel control procedure. Unnecessarily increasing the load on the channel control device according to the present invention by utilizing the extra field of information to be received from the wireless terminal. Without fail.
したがって、 無線端末との連係と、 その連係によって達成される分散処理との 下で、 構成の簡略化に併せて、 信頼性の向上が図られる。  Therefore, the reliability is improved along with the simplification of the configuration under the linkage with the wireless terminal and the distributed processing achieved by the linkage.
本発明にかかわる第八のチャネル制御装置の原理は 下記の通りである。  The principle of the eighth channel control device according to the present invention is as follows.
記憶手段 1 3には、無線ゾーンを介してアクセスし得る無線端末が登録される。 制御手段 1 1は、 この無線ゾーンを介してアクセスした無線端末が記憶手段 1 3 に登録されていないときに、 この無線端末にかかわるチャネル制御の過程で識別 された事象に基づいて、 そのチャネル制御の続行と、 記憶手段 1 3に対するこの 無線端末の登録との双方もしくは何れか一方を行う。  In the storage means 13, a wireless terminal that can be accessed via the wireless zone is registered. When the wireless terminal accessed via this wireless zone is not registered in the storage means 13, the control means 11 performs the channel control based on the event identified in the channel control process for the wireless terminal. And / or registration of this wireless terminal in the storage means 13 is performed.
すなわち、 無線ゾーンを介してアクセスした無線端末にかかわるチャネル制御 は、 その無線ゾーンが予め記憶手段 1 3に登録された無線ゾーンに該当しない場 合には、 このチャネル制御の手順に基づいて適宜続行され、 その記憶手段 1 3に 対して該当する無線ゾーンが登録される。  That is, if the wireless zone does not correspond to the wireless zone registered in the storage means 13 in advance, the channel control for the wireless terminal accessed via the wireless zone is appropriately continued based on the channel control procedure. The corresponding wireless zone is registered in the storage means 13.
したがって、 通信サービスの提供の規制を目的として行われるチャネル制御の 規制は、 そのチャネル制御の対象である無線端末が単に移動しているときに行わ れる場合に比べて、多様なゾ一ン構成に柔軟に適応する形態で実現される。また、 無線端末によるアクセスが許容されるべき個々の無線ゾーンは、 人手を介するこ となく自動的に記憶手段 1 3に登録される。  Therefore, the regulation of channel control, which is performed for the purpose of restricting the provision of communication services, has a wider variety of zonal configurations than the case where the wireless terminal to be controlled is simply moved. It is realized in a form that flexibly adapts. Also, individual wireless zones to which access by wireless terminals should be permitted are automatically registered in the storage means 13 without manual intervention.
本発明にかかわる第九のチャネル制御装置の原理は、 下記の通りである。  The principle of the ninth channel control device according to the present invention is as follows.
測位手段 1 2は、 無線ゾーンを介してアクセスした無線端末が記憶手段 1 3に 登録されていないことが識別される時点まで、 この無線端末の位置を求める処理 を保留する。  The positioning means 12 suspends the processing for obtaining the position of the wireless terminal until it is determined that the wireless terminal accessed via the wireless zone is not registered in the storage means 13.
すなわち、 チャネル制御の過程では、 そのチャネル制御の対象である無線端末 の測位にかかわる処理は、このような測位が必要である場合に限つて機能される。 したがって、 このような測位の要否の如何にかかわらず上述した処理がチヤネ ル制御の過程で起動される場合に比べて、 チャネル制御に要する平均的な処理量 が削減される。  That is, in the process of channel control, the processing related to the positioning of the wireless terminal that is the target of the channel control functions only when such positioning is necessary. Therefore, the average amount of processing required for channel control is reduced compared to the case where the above-described processing is started in the course of channel control regardless of whether or not positioning is required.

すなわち、 記憶手段 1 3には、 「個々の無線ゾーンを介してアクセスし得る無 • 線端末」 が無線端末毎ではなくこれらの無線ゾーン毎に登録される。  In other words, “wireless terminals that can be accessed via individual wireless zones” are registered in storage means 13 for each of these wireless zones, not for each wireless terminal.
したがって、 無線ゾーンの総数に比べて無線端末の総数が少ないほど、 記憶手 段 1 3の参照およびチャネル制御にかかわる処理の簡略化と、 その処理に要する 処理量の削減が図られる。  Therefore, the smaller the total number of wireless terminals is compared to the total number of wireless zones, the simplification of the processing relating to the reference to the storage means 13 and the channel control and the reduction of the processing amount required for the processing are achieved.

A combination of wireless zones is registered in the storage means 13 for each wireless terminal. The control means 11 sets the priority of the wireless zones other than the latest wireless zone accessed for each wireless terminal in the wireless zones registered in the storage means 13 in descending chronological order. Maintain and delete the wireless zone whose priority is lower than the specified lower limit.
すなわち、 記憶手段 1 3に無線端末毎に登録された無線ゾーンの内、 該当する 無線端末によるアクセスが長い時間に豆って行われていない無線ゾーンは、 自動 的に削除される。  That is, of the wireless zones registered in the storage means 13 for each wireless terminal, a wireless zone that has not been accessed by the corresponding wireless terminal for a long time is automatically deleted.
したがって、 個々の無線端末によってアクセスされ得ない無線ゾーンが記憶手 段 1 3に無用に登録され続けることが回避され、 このような記憶手段 1 3の参照 を伴うチヤネル制御の効率がおよび応答性が高く維持される。  Therefore, it is possible to prevent wireless zones that cannot be accessed by individual wireless terminals from being unnecessarily registered in the storage means 13, and the efficiency and responsiveness of such channel control with reference to the storage means 13 are improved. Will be kept high.

The control unit 11 communicates between the deleted one of the wireless zones registered in the storage unit 13 and the latest wireless zone accessed by the wireless terminal associated with the wireless zone. Output an identifier.
すなわち、 長時間に渡って無線端末によってアクセスされなかったために記憶 手段 1 3から何らかの無線ゾーンが削除されたときには、 その無線ゾーンに併せ て、 この無線端末によってアクセスされた最新の無線ゾ一ンが適宜通知される。 したがって、 記憶手段 1 3の更新が人手を介することなく自動的に行われるに もかかわらず、 保守や運用に携わる要員は、 その記憶手段 1 3に引き続いて登録 されている無線ゾーンを的確に把握することが可能となる。  That is, when any wireless zone is deleted from the storage means 13 because it has not been accessed by the wireless terminal for a long time, the latest wireless zone accessed by this wireless terminal is also added to the wireless zone. Notified as appropriate. Therefore, despite the automatic updating of the storage means 13 without manual intervention, the personnel engaged in maintenance and operation can accurately grasp the wireless zone registered subsequently to the storage means 13. It is possible to do.
