Description

通信制御システム、基地局装置、通信制御方法、及びプログラムを格納した非一時的なコンピュータ可読媒体Communication control system, base station apparatus, communication control method, and non-transitory computer-readable medium storing program
　本発明は、移動通信システムにおける移動局の通信制御に関し、特に、移動基地局に接続する移動局の通信制御に関する。 The present invention relates to communication control of a mobile station in a mobile communication system, and more particularly to communication control of a mobile station connected to a mobile base station.
　電車、バス、航空機等の移動装置に設置される基地局が知られている。このような基地局は設置場所が固定されておらず移動性を有するため、「移動基地局」と呼ばれる。 Base stations installed on mobile devices such as trains, buses and aircraft are known. Such a base station is called a “mobile base station” because its installation location is not fixed and has mobility.
　なお、近年、フェムトセル基地局又はホーム基地局などと呼ばれる超小型の基地局が実用化されている。このような基地局は、移動通信サービスの利用者の宅内等に設置されることから、移動通信サービス事業者がその設置場所を把握することが困難である。そのため、フェムトセル基地局が周辺基地局からの無線信号を受信することで得られる周辺基地局の識別子や受信電力測定値を用いることによって、又はフェムトセル基地局若しくはフェムトセル基地局に接続する移動局に搭載されたＧＰＳ（Global Positioning System）受信機によって得られる位置情報を用いることによって、フェムトセル基地局の設置場所をコアネットワーク側で把握できるようにする技術が知られている（例えば、特許文献１を参照）。 In recent years, ultra-small base stations called femtocell base stations or home base stations have been put into practical use. Since such a base station is installed in the home of a mobile communication service user, it is difficult for the mobile communication service provider to grasp the installation location. Therefore, a femtocell base station uses a peripheral base station identifier or received power measurement value obtained by receiving a radio signal from a peripheral base station, or moves connected to a femtocell base station or a femtocell base station. A technique is known that enables the location of a femtocell base station to be determined on the core network side by using position information obtained by a GPS (Global Positioning System) receiver mounted on a station (for example, a patent) Reference 1).
　また、病院内や航空機内などの特定場所における移動局の使用を強制的に制限するために、これらの特定場所に設置された基地局から移動局に制御信号を送出することによって移動局の通信を制限する技術が知られている（例えば、特許文献２及び３を参照）。 In addition, in order to forcibly restrict the use of mobile stations in specific locations such as hospitals and airplanes, mobile station communication is performed by sending control signals to mobile stations from base stations installed in these specific locations. There are known techniques for limiting the above (for example, see Patent Documents 2 and 3).

　電車及びバス等の公共交通機関において移動局を用いた通話・通信を行うと周囲の乗客の迷惑になる場合がある等の理由によって、電車及びバス等の移動装置内における移動局の使用を制限することが望まれている。この要求に対処するため、上述した特許文献２及び３等は、移動装置内等の特定場所に設置された基地局に接続する移動局の通信を制限することを開示している。 Restricting the use of mobile stations in mobile devices such as trains and buses when talking or communicating using mobile stations in public transportation such as trains and buses may cause annoyance to nearby passengers It is hoped to do. In order to cope with this requirement, Patent Documents 2 and 3 described above disclose that communication of a mobile station connected to a base station installed in a specific place such as in a mobile device is restricted.
　本願の発明者は、特許文献２及び３に開示された技術では、移動局の通信規制を電車及びバス等の移動装置の移動状態に応じて柔軟に行うことができないという問題があることを見出した。例えば、電車が駅に停車中である場合に移動局に着呼があった場合、移動局の利用者は直ぐに電車から降りて通話を開始することができるため、移動局の通信規制を行う必要性が低いと考えられる。しかしながら、特許文献２及び３に開示された技術では、電車内において移動局の通信を一律に抑制するといった制御しか行うことができない。 The inventor of the present application has found that the technologies disclosed in Patent Documents 2 and 3 have a problem that the communication restriction of a mobile station cannot be flexibly performed according to the movement state of a mobile device such as a train and a bus. It was. For example, if a mobile station receives an incoming call when the train is stopped at a station, the mobile station user can immediately get off the train and start talking. It is thought that the nature is low. However, the techniques disclosed in Patent Documents 2 and 3 can only perform control such as uniformly suppressing communication of mobile stations in a train.
　なお、特許文献１に開示された技術は、基地局が設置された位置を把握することで、基地局が過去の設置場所から変更されたか否かをコアネットワークが検知するに過ぎない。言い換えると、特許文献１は、基地局がまさに移動中であるか否かを判定すること、及び基地局が移動中であるかに応じた移動局の通信規制に関して何ら開示していない。 In the technology disclosed in Patent Document 1, the core network only detects whether or not the base station has been changed from the past installation location by grasping the position where the base station is installed. In other words, Patent Document 1 does not disclose anything about determining whether or not the base station is moving, and communication restrictions of the mobile station depending on whether or not the base station is moving.
　本発明は、上述した発明者の知見に基づいてなされたものであって、基地局が電車及びバス等の移動装置に設置される事情に適応して、移動局の通信に対する規制を柔軟に行うことが可能な通信制御システム、基地局装置、通信制御方法、及びプログラムの提供を目的とする。 The present invention has been made on the basis of the above-described knowledge of the inventor, and flexibly regulates communication of mobile stations in accordance with the situation where base stations are installed in mobile devices such as trains and buses. An object of the present invention is to provide a communication control system, a base station apparatus, a communication control method, and a program that can be used.
　本発明の第１の態様は、通信制御システムを含む。当該通信制御システムは、基地局が移動中であると判定されるか否かに応じて、前記基地局に接続する移動局の通信に対する規制内容を変更する制御部を有する。 The first aspect of the present invention includes a communication control system. The communication control system includes a control unit that changes a restriction on communication of a mobile station connected to the base station depending on whether or not the base station is determined to be moving.
　本発明の第２の態様は、移動局と上位ネットワークの間の通信を中継する基地局装置を含む。当該基地局装置は、前記基地局装置が移動中であると判定されるか否かに応じて、前記移動局の通信に対する規制内容を変更する制御部を有する。 The second aspect of the present invention includes a base station device that relays communication between a mobile station and an upper network. The base station apparatus includes a control unit that changes a restriction on communication of the mobile station depending on whether or not the base station apparatus is determined to be moving.
　本発明の第３の態様は、通信制御方法を含む。当該通信制御方法は、基地局が移動中であると判定されるか否かに応じて、前記基地局に接続する移動局の通信に対する規制内容を変更することを含む。 The third aspect of the present invention includes a communication control method. The communication control method includes changing a restriction on communication of a mobile station connected to the base station depending on whether or not the base station is determined to be moving.
　本発明の第４の態様は、基地局に接続する移動局の通信制御方法をコンピュータに行わせるためのプログラムを含む。当該プログラムの実行により行われる通信制御方法は、基地局が移動中であると判定されるか否かに応じて、前記基地局に接続する移動局の通信に対する規制内容を変更することを含む。 The fourth aspect of the present invention includes a program for causing a computer to perform a communication control method for a mobile station connected to a base station. The communication control method performed by executing the program includes changing the content of restriction on communication of the mobile station connected to the base station, depending on whether or not the base station is determined to be moving.
　上述した本発明の各態様によれば、基地局が電車及びバス等の移動装置に設置される事情に適応して、移動局の通信に対する規制を柔軟に行うことが可能な通信制御システム、基地局装置、通信制御方法、及びプログラムを提供できる。 According to each aspect of the present invention described above, a communication control system and a base that can flexibly regulate the communication of the mobile station in accordance with the situation where the base station is installed in a mobile device such as a train and a bus.

　以下では、本発明を適用した具体的な実施の形態について、図面を参照しながら詳細に説明する。各図面において、同一要素には同一の符号が付されており、説明の明確化のため、必要に応じて重複説明は省略される。 Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted as necessary for the sake of clarity.
＜発明の実施の形態１＞
　図１は、本実施の形態にかかる移動通信システムの構成例を示すブロック図である。移動基地局１０は、移動装置８０内に設置され、移動装置８０の移動に従って移動する。移動装置８０は、例えば、電車又はバスである。移動基地局１０は、移動装置８０内に位置する移動局１１とコアネットワーク１２の間の通信を中継する。 <Embodiment 1 of the Invention>
FIG. 1 is a block diagram showing a configuration example of a mobile communication system according to the present embodiment. The mobile base station 10 is installed in the mobile device 80 and moves according to the movement of the mobile device 80. The moving device 80 is, for example, a train or a bus. The mobile base station 10 relays communication between the mobile station 11 located in the mobile device 80 and the core network 12.
　通信制御システム１００は、移動中判定部１３及び端末通信制御部１４を含む。移動中判定部１３は、移動基地局１０が移動中であるか否かを判定する。具体的には、移動中判定部１３は、移動基地局１０の位置判定に利用可能な情報（以下、位置判定情報と呼ぶ）を繰り返し取得し、位置判定情報の時間変化、又は位置判定情報から推定される移動基地局１０の位置の時間変化を監視することによって、移動基地局１０が移動中であるか否かを判定すればよい。移動中判定部１３は、位置判定情報を移動基地局１０から受信すればよい。 The communication control system 100 includes a moving determination unit 13 and a terminal communication control unit 14. The moving determination unit 13 determines whether or not the mobile base station 10 is moving. Specifically, the moving determination unit 13 repeatedly acquires information that can be used for position determination of the mobile base station 10 (hereinafter referred to as position determination information), and changes the position determination information with time or position determination information. What is necessary is just to determine whether the mobile base station 10 is moving by monitoring the time change of the position of the mobile base station 10 estimated. The moving determination unit 13 may receive the position determination information from the mobile base station 10.
　位置判定情報の一例として、移動基地局１０の周囲に位置する周辺基地局の基地局ＩＤを利用することができる。また、周辺基地局の基地局ＩＤに代えて、又は周辺基地局の基地局ＩＤと組み合わせて、周辺基地局から送信される無線信号（例えばパイロット信号）の受信品質を位置判定情報として用いてもよい。無線信号の受信品質とは、例えば、受信電力、ＳＩＲ（Signal to Interference Ratio）である。最隣接の周辺基地局の基地局ＩＤの時間変化、若しくは受信品質の時間変化、又はこれらの組合せを監視することで、移動基地局１０が移動中であるか、又は実質的に静止しているのかを判定することができる。 As an example of the position determination information, base station IDs of peripheral base stations located around the mobile base station 10 can be used. Further, instead of the base station ID of the peripheral base station or in combination with the base station ID of the peripheral base station, the reception quality of a radio signal (for example, a pilot signal) transmitted from the peripheral base station may be used as the position determination information. Good. The reception quality of the radio signal is, for example, reception power and SIR (Signal-to-Interference Ratio). The mobile base station 10 is moving or substantially stationary by monitoring the time change of the base station ID of the nearest neighbor base station, the time change of the reception quality, or a combination thereof. Can be determined.
　また、位置判定情報として、ＧＰＳ(Global Positioning System)受信機によって取得される位置情報を用いてもよい。この場合、ＧＰＳ受信機は、移動基地局１０に搭載されてもよいし、移動局１１に搭載されてもよいし、移動装置８０に設置されてもよい。移動局１１に搭載されたＧＰＳ受信機を利用する場合、移動基地局１０は、移動局１１から位置情報を受信すればよい。また、移動装置８０に設置されたＧＰＳ受信機を利用する場合、移動基地局１０にＬＡＮ（Local Area Network）インタフェースを設け、移動装置８０の情報システムを介して位置情報を移動基地局１０に送ればよい。 Further, as the position determination information, position information acquired by a GPS (Global Positioning System) receiver may be used. In this case, the GPS receiver may be mounted on the mobile base station 10, the mobile station 11, or the mobile device 80. When using a GPS receiver mounted on the mobile station 11, the mobile base station 10 may receive position information from the mobile station 11. When a GPS receiver installed in the mobile device 80 is used, the mobile base station 10 can be provided with a LAN (Local Area Network) interface, and position information can be sent to the mobile base station 10 via the information system of the mobile device 80. That's fine.
　端末通信制御部１４は、移動中判定部１３によって移動基地局１０が移動中状態であると判定されるか否かに応じて、移動局１１の通信に対する規制内容を変更する。具体的には、移動基地局１０が移動中であると判定される場合には、移動基地局１０が実質的に静止していると判定される場合に比べて、移動局１１の上り通信又は下り通信のうち少なくとも一方を抑制する。例えば、端末通信制御部１４は、移動基地局１０が移動中であると判定される場合に、移動局１１からの通信要求（発呼）に基づく通信、及びコアネットワーク１２から到達する通信要求（着呼）に基づく通信のうち少なくとも一方を禁止してもよい。 The terminal communication control unit 14 changes the content of restriction on the communication of the mobile station 11 depending on whether or not the mobile base station 10 is determined to be in the moving state by the moving determination unit 13. Specifically, when it is determined that the mobile base station 10 is moving, the uplink communication of the mobile station 11 or when the mobile base station 10 is determined to be substantially stationary At least one of the downlink communications is suppressed. For example, when it is determined that the mobile base station 10 is moving, the terminal communication control unit 14 performs communication based on a communication request (call) from the mobile station 11 and communication request ( At least one of communication based on an incoming call may be prohibited.
　図２は、端末通信制御部１４による通信規制処理手順の具体例を示すフローチャートである。ステップＳ１１では、端末通信制御部１４は、移動基地局１０が「移動中状態」であるか否か確認する。本明細書で用いる「移動中状態」との用語は、基地局が実質的に静止しておらず移動中であると判定された状態、又は移動中に対応した基地局の動作状態を意味する。移動基地局１０が「移動中状態」でない場合（ステップＳ１１でＮＯ）、端末通信制御部１４は、移動局１１に対する通信規制を相対的に緩和する（ステップＳ１２）。一方、移動基地局１０が「移動中状態」である場合（ステップＳ１１でＹＥＳ）、端末通信制御部１４は、移動局１１に対する通信規制を相対的に強化する（ステップＳ１３）。 FIG. 2 is a flowchart showing a specific example of a communication restriction processing procedure by the terminal communication control unit 14. In step S11, the terminal communication control unit 14 checks whether or not the mobile base station 10 is in the “moving state”. As used herein, the term “moving state” means a state in which a base station is determined not to be substantially stationary and moving, or an operating state of a corresponding base station during movement. . If the mobile base station 10 is not in the “moving state” (NO in step S11), the terminal communication control unit 14 relatively relaxes communication restrictions on the mobile station 11 (step S12). On the other hand, when the mobile base station 10 is in the “moving state” (YES in step S11), the terminal communication control unit 14 relatively strengthens communication restrictions on the mobile station 11 (step S13).
　本実施の形態で説明した通信制御システム１００によれば、移動基地局１０が移動中であると判定されるか否かに応じて、移動基地局１０に接続する移動局１１の通信に対する規制内容を変更することができる。このため、移動基地局１０が電車及びバス等の移動装置８０に設置される場合に、移動装置８０が移動中であるときは移動局１１の通信規制を強化し、移動装置８０が実質的に停止している際には移動局１１の通信規制を緩和する等の通信規制を行うことができる。つまり、通信制御システム１００によれば、移動基地局１０が電車及びバス等の移動装置８０に設置される事情に適応して、移動局１１の通信に対する規制を柔軟に行うことができる。 According to communication control system 100 described in the present embodiment, depending on whether or not mobile base station 10 is determined to be moving, the content of restrictions on communication of mobile station 11 connected to mobile base station 10 Can be changed. For this reason, when the mobile base station 10 is installed in a mobile device 80 such as a train and a bus, when the mobile device 80 is moving, the communication regulation of the mobile station 11 is strengthened, and the mobile device 80 is substantially When it is stopped, it is possible to perform communication regulation such as relaxation of communication regulation of the mobile station 11. That is, according to the communication control system 100, it is possible to flexibly regulate the communication of the mobile station 11 in accordance with the situation where the mobile base station 10 is installed in the mobile device 80 such as a train and a bus.

For example, the mobile base station 10 regulates communication based on a communication request (calling) from the mobile station 11 and the communication restriction based on a communication request (incoming call) arriving from the core network 12 is arranged in the core network 12 May be performed by the device.

　本実施の形態で述べた通信制御システム１００の変形について、以下に述べる発明の実施の形態２～６において詳しく説明する。 Modifications of the communication control system 100 described in this embodiment will be described in detail in Embodiments 2 to 6 of the invention described below.
＜発明の実施の形態２＞
　図３は、本実施の形態にかかる移動通信システムの構成例を示すブロック図である。本実施の形態では、移動基地局２０が移動中であるか否かの判定とコアネットワーク１２から到達する通信要求（着呼）に基づく通信の規制を基地局管理装置２３が行い、移動局１１からの通信要求（発呼）に基づく通信の規制を移動基地局２０が行う。 <Embodiment 2 of the Invention>
FIG. 3 is a block diagram showing a configuration example of the mobile communication system according to the present embodiment. In the present embodiment, the base station management device 23 performs communication regulation based on a determination as to whether or not the mobile base station 20 is moving and a communication request (incoming call) that arrives from the core network 12. The mobile base station 20 regulates communication based on a communication request (call) from the mobile phone.
　図４は、移動基地局２０の構成例を示すブロック図である。図４において、端末通信部２００は、移動局１１との通信に使うプロトコルを用いて、移動局１１との間でデータ送受信を行うための無線通信経路を確立する。コア網通信部２０１は、コア網との通信に使うプロコトルを用いて、コアネットワーク１２との間でデータ送受信を行うための無線通信経路を確立する。なお、コア網通信部２０１は、無線アクセスネットワーク内の他の基地局や中継局を経由してコアネットワーク１２と通信を行ってもよい。 FIG. 4 is a block diagram illustrating a configuration example of the mobile base station 20. In FIG. 4, the terminal communication unit 200 establishes a wireless communication path for performing data transmission / reception with the mobile station 11 using a protocol used for communication with the mobile station 11. The core network communication unit 201 establishes a wireless communication path for performing data transmission / reception with the core network 12 using a protocol used for communication with the core network. The core network communication unit 201 may communicate with the core network 12 via other base stations and relay stations in the radio access network.
　位置検出部２０２は、位置判定情報を取得し、これを基地局管理装置２３にコア網通信部２０１を経由して送信する。位置判定情報の具体例については、実施の形態１で既に述べたのでここでは説明を省略する。 The location detection unit 202 acquires location determination information and transmits it to the base station management device 23 via the core network communication unit 201. Since a specific example of the position determination information has already been described in the first embodiment, description thereof is omitted here.
　続いて、基地局管理装置２３について説明する。基地局管理装置２３は、コアネットワーク１２、又はコアネットワーク１２と無線アクセスネットワークの境界に配置される。基地局管理装置２３は、管理対象の移動基地局２０の無線リソース制御、送信電力等の無線パラメータ制御、移動基地局２０に接続する移動局１１の通信制御を行う。例えば、ＵＭＴＳ（Universal Mobile Telecommunications System）の場合、基地局管理装置２３はＲＮＣ（Radio Network Controller）に相当する。 Subsequently, the base station management device 23 will be described. The base station management device 23 is arranged at the core network 12 or the boundary between the core network 12 and the radio access network. The base station management device 23 performs radio resource control of the mobile base station 20 to be managed, radio parameter control such as transmission power, and communication control of the mobile station 11 connected to the mobile base station 20. For example, in the case of UMTS (Universal Mobile Telecommunications System), the base station management device 23 corresponds to an RNC (Radio Network Controller).
　図５は、基地局管理装置２３の構成例を示すブロック図である。基地局通信部２３０は、管理対象の移動基地局２０との通信を担う。基地局制御部２３１は、管理対象の移動基地局２０のパラメータの制御を行う。移動基地局２０が移動している場合には、例えば移動基地局２０の無線送信電力を適切に制御する必要がある。このため、移動基地局２０およびその周囲に位置する周辺基地局の送信電力の調整を行う。 FIG. 5 is a block diagram showing a configuration example of the base station management device 23. As shown in FIG. The base station communication unit 230 is responsible for communication with the mobile base station 20 to be managed. The base station control unit 231 controls parameters of the mobile base station 20 to be managed. When the mobile base station 20 is moving, for example, it is necessary to appropriately control the radio transmission power of the mobile base station 20. For this reason, the transmission power of the mobile base station 20 and peripheral base stations located around the mobile base station 20 is adjusted.
　位置履歴記憶部２３２は、移動基地局２０から受信される位置判定情報を保持する。位置履歴記憶部２３２は、例えば、図６Ａ及び６Ｂに示すような位置履歴テーブルを保持すればよい。図６Ａ及び６Ｂに示す位置履歴テーブルは、移動基地局２０から受信した位置判定情報とその取得時刻が記録されている。図６Ａの位置履歴テーブルは、周辺基地局の基地局ＩＤ及び受信電力を位置判定情報として使用する場合の具体例である。図６Ｂの位置履歴テーブルは、ＧＰＳ受信機によって取得される位置情報（緯度及び経度）を位置判定情報として使用する場合の具体例である。 The location history storage unit 232 holds location determination information received from the mobile base station 20. The position history storage unit 232 may hold a position history table as shown in FIGS. 6A and 6B, for example. In the position history table shown in FIGS. 6A and 6B, position determination information received from the mobile base station 20 and its acquisition time are recorded. The position history table in FIG. 6A is a specific example in the case of using the base station IDs and received power of neighboring base stations as position determination information. The position history table of FIG. 6B is a specific example in the case of using position information (latitude and longitude) acquired by a GPS receiver as position determination information.
　図６Ａの例では、再隣接の基地局（＃１）から第３隣接の基地局（＃３）までの情報を保持可能である。例えば、２０１０年３月１１日１２時０９分のレコードを見ると、再隣接基地局の基地局ＩＤが「ＲＲ」であり、この基地局からの受信電力が－１５ｄＢｍであることが記録されている。なお、必ずしも複数の周辺基地局ＩＤが必要というわけではなく、再隣接基地局の基地局ＩＤのみを用いて移動基地局２０が移動中か否かを検出することも可能である。この場合、移動基地局２０は、最も強い受信電力を観測した周辺基地局の基地局ＩＤのみを基地局管理装置２３に送信してもよい。 In the example of FIG. 6A, information from the re-adjacent base station (# 1) to the third adjacent base station (# 3) can be retained. For example, when viewing a record of 12:09 on March 11, 2010, it is recorded that the base station ID of the re-adjacent base station is “RR” and the received power from this base station is −15 dBm. Yes. A plurality of neighboring base station IDs are not necessarily required, and it is also possible to detect whether or not the mobile base station 20 is moving using only the base station ID of the re-adjacent base station. In this case, the mobile base station 20 may transmit only the base station ID of the peripheral base station that observed the strongest received power to the base station management device 23.
　図５に戻って説明を続ける。移動中判定部２３３は、移動基地局２０が移動中であるか否かを判定する。具体的には、移動中判定部２３３は、位置履歴記憶部２３２にアクセスし、移動基地局２０から報告された位置判定情報の時間変化、又は位置判定情報から推定される移動基地局２０の位置の時間変化を監視することによって、移動基地局２０が移動中であるか否かを判定する。 Referring back to FIG. The moving determination unit 233 determines whether or not the mobile base station 20 is moving. Specifically, the in-movement determination unit 233 accesses the position history storage unit 232 and changes the position determination information reported from the mobile base station 20 over time, or the position of the mobile base station 20 estimated from the position determination information. Is monitored to determine whether or not the mobile base station 20 is moving.
　例えば、図６Ａの位置履歴テーブルを使用する場合、移動中判定部２３３は、隣接基地局のＩＤの時間変化を検出することによって、移動基地局２０が移動中であることを判定すればよい。具体的には、図６Ａの例では、１２時０９分～１６分にわたり、隣接基地局のＩＤが連続して変化している。この変化を基地局管理装置５０１が検出し、移動基地局２０が移動中であることを判定すればよい。例えば、最新の取得時刻とその１つ前の取得時刻との間で、隣接接基地局＃１～＃３のうち少なくとも１つの基地局ＩＤが変化した場合に、移動基地局２０が移動中であることを判定してもよい。 For example, when the position history table of FIG. 6A is used, the moving determination unit 233 may determine that the mobile base station 20 is moving by detecting the temporal change in the ID of the adjacent base station. Specifically, in the example of FIG. 6A, the IDs of adjacent base stations continuously change from 12:09 to 16 minutes. This change may be detected by the base station management apparatus 501 and it may be determined that the mobile base station 20 is moving. For example, the mobile base station 20 is moving when at least one base station ID of the adjacent base stations # 1 to # 3 changes between the latest acquisition time and the previous acquisition time. You may determine that there is.
　なお、移動中判定部２３３は、図６Ａの位置履歴テーブルに記録された基地局ＩＤ及び受信電力を用いた計算によって移動基地局２０の位置を推定してもよい。この場合、推定された位置の時間変化に基づいて、移動基地局２０が移動中であることを判定すればよい。 Note that the moving determination unit 233 may estimate the position of the mobile base station 20 by calculation using the base station ID and the received power recorded in the position history table of FIG. 6A. In this case, it is only necessary to determine that the mobile base station 20 is moving based on the estimated time change of the position.
　また、例えば、図６Ｂの位置履歴テーブルを使用する場合、移動中判定部２３３は、移動基地局２０の位置（緯度及び経度）の時間変化を検出することによって、移動基地局２０が移動中であることを判定すればよい。 For example, when the position history table of FIG. 6B is used, the moving determination unit 233 detects the time change of the position (latitude and longitude) of the mobile base station 20 so that the mobile base station 20 is moving. What is necessary is just to determine that there exists.
　移動中判定部２３３は、例えば、図７に示すような基地局状態テーブルを用いて移動基地局２０の状態を管理してもよい。図７の例では、移動基地局２０が移動中であると判定された場合に移動中フラグを設定（例えば値"１"）し、移動基地局２０が移動中でない、言い換えると実質的に静止していると判定された場合に移動中フラグを解除（例えば値"０"）すればよい。また、基地局状態テーブルは、図７に示す移動中フラグに加えて、最新の位置判定情報および取得時刻を記録してもよい。 The moving determination unit 233 may manage the state of the mobile base station 20 using, for example, a base station state table as shown in FIG. In the example of FIG. 7, when it is determined that the mobile base station 20 is moving, a moving flag is set (for example, value “1”), and the mobile base station 20 is not moving, in other words, substantially stationary. If it is determined that the movement is in progress, the moving flag may be canceled (for example, the value “0”). The base station state table may record the latest position determination information and acquisition time in addition to the moving flag shown in FIG.
　図５に示す端末通信制御部２３４は、移動基地局２０に接続する移動局１１に関する通信の制御を行う。具体的には、コアネットワーク１２側から移動局１１に対する通信や、移動局１１からコアネットワーク１２への通信の制御を行う。また、本実施の形態では、端末通信制御部２３４は、移動中判定部２３３によって移動基地局２０が移動中と判定された場合に、コアネットワーク１２側から移動局１１に対する通信の規制を行う。この規制の内容は、例えば、コアネットワーク１２側から移動局１１に対する全ての通信要求を拒絶するものでもよいし、確率的に一部の通信要求を拒絶するものでもよいし、特定種別の通信要求（例えば音声通話）を拒絶するものでもよい。 The terminal communication control unit 234 shown in FIG. 5 controls communication related to the mobile station 11 connected to the mobile base station 20. Specifically, communication from the core network 12 side to the mobile station 11 and communication from the mobile station 11 to the core network 12 are controlled. Further, in the present embodiment, the terminal communication control unit 234 regulates communication from the core network 12 side to the mobile station 11 when the moving base station 20 determines that the mobile base station 20 is moving. The content of this regulation may be, for example, a rejection of all communication requests from the core network 12 side to the mobile station 11, a rejection of a part of communication requests stochastically, or a specific type of communication request (For example, a voice call) may be rejected.
　続いて以下では、フローチャート及びシーケンス図を用いて、移動基地局２０が移動中であるか否かの判定手順および移動局１１に対する通信規制手順の具体例について説明する。図８は、移動基地局２０による位置判定情報の送信手順の具体例を示すフローチャートである。ステップＳ２１では、位置検出部２０２は、位置判定情報を取得する。ステップＳ２２では、位置検出部２０２は、コア網通信部２０１を介して、位置判定情報を基地局管理装置２３に送信する。 Subsequently, a specific example of a determination procedure for determining whether or not the mobile base station 20 is moving and a communication restriction procedure for the mobile station 11 will be described using a flowchart and a sequence diagram. FIG. 8 is a flowchart showing a specific example of a procedure for transmitting position determination information by the mobile base station 20. In step S <b> 21, the position detection unit 202 acquires position determination information. In step S <b> 22, the position detection unit 202 transmits position determination information to the base station management device 23 via the core network communication unit 201.
　図９は、基地局管理装置２３によって行われる、移動基地局２０が移動中であるか否かの判定手順の具体例を示すフローチャートである。ステップＳ３１では、基地局通信部２３０は、移動基地局２０から位置判定情報を受信し、これを位置履歴記憶部２３２に格納する。ステップＳ３２では、移動中判定部２３３は、位置履歴記憶部２３２にアクセスし、移動基地局２０が移動中であるか否かを判定する。移動中と判定された場合（ステップＳ３２でＹＥＳ）、移動中判定部２３３は、基地局状態テーブル（例えば図７）に移動基地局２０が移動中であることを示すフラグを設定する。ステップＳ３４では、移動中判定部２３３は、基地局通信部２３０を介して、移動基地局２０に対して移動中状態であることを通知する。なお、ステップＳ３４は、行わなくてもよい。ステップＳ３４を行わない場合、基地局管理装置２３は、移動基地局２０からの問い合わせに応じて、移動基地局２０に対して移動中状態であるか否かを回答すればよい。 FIG. 9 is a flowchart showing a specific example of a procedure for determining whether or not the mobile base station 20 is moving, which is performed by the base station management device 23. In step S <b> 31, the base station communication unit 230 receives the position determination information from the mobile base station 20 and stores it in the position history storage unit 232. In step S32, the moving determination unit 233 accesses the position history storage unit 232 and determines whether or not the mobile base station 20 is moving. If it is determined that the mobile base station 20 is moving (YES in step S32), the moving determination unit 233 sets a flag indicating that the mobile base station 20 is moving in the base station state table (for example, FIG. 7). In step S <b> 34, the moving determination unit 233 notifies the mobile base station 20 of the moving state via the base station communication unit 230. Step S34 may not be performed. When step S34 is not performed, the base station management device 23 may reply to the mobile base station 20 whether or not it is in a moving state in response to an inquiry from the mobile base station 20.
　図１０は、移動基地局２０によって行われる、移動局１１からコアネットワーク１２への通信（発呼）の規制手順の具体例を示すフローチャートである。ステップＳ４１では、端末通信制御部２０３は、移動局１１からの通信要求を受信したか否かを検査する。ステップＳ４２では、端末通信制御部２０３は、移動基地局２０が移動中状態であるか否かを確認する。この確認は、基地局管理装置２３に問い合わせることによって行ってもよいし、事前に基地局管理装置２３から状態変化通知（図９のＳ３４）を受けている場合には、その通知に基づいて確認すればよい。ステップＳ４２にて移動中状態でないと確認された場合、端末通信制御部２０３は、移動局１１からの通信要求をコアネットワーク１２に送信する（ステップＳ４３）。一方、ステップＳ４２にて移動中状態であると確認された場合、端末通信制御部２０３は、移動局１１からの通信要求をコアネットワーク１２に通知せずに終了する（ステップＳ４４）。 FIG. 10 is a flowchart showing a specific example of a restriction procedure for communication (calling) from the mobile station 11 to the core network 12 performed by the mobile base station 20. In step S41, the terminal communication control unit 203 checks whether a communication request from the mobile station 11 has been received. In step S42, the terminal communication control unit 203 confirms whether or not the mobile base station 20 is in a moving state. This confirmation may be performed by making an inquiry to the base station management apparatus 23. If a state change notification is received from the base station management apparatus 23 in advance (S34 in FIG. 9), confirmation is made based on the notification. do it. When it is confirmed in step S42 that the mobile station is not moving, the terminal communication control unit 203 transmits a communication request from the mobile station 11 to the core network 12 (step S43). On the other hand, when it is confirmed in step S42 that the mobile terminal is in the moving state, the terminal communication control unit 203 ends without notifying the core network 12 of a communication request from the mobile station 11 (step S44).
　図１１は、基地局管理装置２３によって行われる、コアネットワーク１２から移動局１１への通信（着呼）の規制手順の具体例を示すフローチャートである。ステップＳ５１では、端末通信制御部２３４は、コアネットワーク１２側から通信要求を受信したか否かを検査する。ステップＳ５２では、端末通信制御部２３４は、通信要求の宛て先移動局が接続している基地局の基地局ＩＤを取得する。この基地局ＩＤの取得は、移動局の登録エリア、登録基地局などを管理する管理装置（例えばＨＬＲ：Home Location Register）に問い合わせることによって行えばよい。そして、端末通信制御部２３４は、取得された基地局ＩＤに対応する基地局が移動中状態であるか否かを確認する。この確認は、図７に示したような基地局状態テーブルを参照することによって行えばよい。 FIG. 11 is a flowchart showing a specific example of a restriction procedure of communication (incoming call) from the core network 12 to the mobile station 11 performed by the base station management device 23. In step S51, the terminal communication control unit 234 checks whether a communication request has been received from the core network 12 side. In step S52, the terminal communication control unit 234 acquires the base station ID of the base station to which the communication request destination mobile station is connected. The base station ID may be acquired by inquiring a management device (for example, HLR: Home Location Register) that manages the registration area of the mobile station, the registered base station, and the like. Then, the terminal communication control unit 234 confirms whether or not the base station corresponding to the acquired base station ID is in a moving state. This confirmation may be performed by referring to the base station state table as shown in FIG.
　ステップＳ５２にて移動中状態でないと確認された場合、端末通信制御部２３４は、移動局１１との通信を開始するべく移動基地局２０及び移動局１１の制御を行う（ステップＳ５３）。一方、ステップＳ５２にて移動中状態であると確認された場合、端末通信制御部２３４は、通信要求の送信元に「通信不可」である旨を通知する。この通知には、通信不可能である理由、すなわち宛て先移動局（移動局１１）が移動中であること、を含めてもよい。 If it is confirmed in step S52 that the mobile station 11 is not moving, the terminal communication control unit 234 controls the mobile base station 20 and the mobile station 11 to start communication with the mobile station 11 (step S53). On the other hand, when it is confirmed in step S52 that the mobile device is in the moving state, the terminal communication control unit 234 notifies the transmission source of the communication request that “communication is impossible”. This notification may include the reason why communication is impossible, that is, that the destination mobile station (mobile station 11) is moving.
　ステップＳ５２にて移動中状態であると確認された場合、さらに、ステップＳ５５及びＳ５６を行ってもよい。ステップＳ５５では、端末通信制御部２３４は、移動基地局２０との間で、現在、通信可能であるかを検査する。通信可能である場合、ステップＳ５６では、端末通信制御部２３４は、拒否された通信要求の存在を移動局１１に通知する。拒否された通信要求の存在を移動局１１に通知することによって、移動局１１は通信要求があったことを知ることができ、移動局１１の画面表示等によって利用者に通知することも可能である。これによって、移動局１１の利用者は、後で移動基地局２０が移動中でなくなった時に通信を開始することができるため、利用者の利便性を大きく損なうことなく、移動中の移動基地局２０に接続する移動局１１の通信を抑制することができる。 If it is confirmed in step S52 that it is in the moving state, steps S55 and S56 may be further performed. In step S55, the terminal communication control unit 234 checks whether communication with the mobile base station 20 is currently possible. If communication is possible, in step S56, the terminal communication control unit 234 notifies the mobile station 11 of the presence of the rejected communication request. By notifying the mobile station 11 of the existence of the rejected communication request, the mobile station 11 can know that there has been a communication request, and can also notify the user by displaying the screen of the mobile station 11 or the like. is there. Thus, since the user of the mobile station 11 can start communication when the mobile base station 20 is not moving later, the mobile base station that is moving without greatly impairing the convenience of the user. Communication of the mobile station 11 connected to 20 can be suppressed.
　次に、シーケンス図を用いて説明する。図１２は、移動基地局２０が移動中か否かの判定を行う場合のシーケンスの一例を示している。ステップＳ６１において、移動基地局２０は、位置判定情報と基地局ＩＤを基地局管理装置２３へ送る。ステップＳ６２では、基地局管理装置２３は、移動基地局２０から位置判定情報及び基地局ＩＤを受信し、位置履歴テーブルを更新する。ステップＳ６３では、移動基地局２０に関する最新の位置判定情報と過去の位置判定情報を比較することによって、移動基地局２０が移動中であるか否かを判定する。移動基地局２０が移動中であると判定された場合、基地局状態テーブル（例えば図７）の移動基地局２０に対応するエントリの移動中フラグを設定する。さらに、基地局管理装置２３は、移動基地局２０に対し「移動中」状態であることを通知してもよい（ステップＳ６５）。この通知を受けた移動基地局２０は、移動中状態に移行する（ステップＳ６６）。 Next, the sequence diagram will be used to explain. FIG. 12 shows an example of a sequence for determining whether or not the mobile base station 20 is moving. In step S <b> 61, the mobile base station 20 sends the position determination information and the base station ID to the base station management device 23. In step S62, the base station management device 23 receives the position determination information and the base station ID from the mobile base station 20, and updates the position history table. In step S63, it is determined whether or not the mobile base station 20 is moving by comparing the latest position determination information related to the mobile base station 20 and the past position determination information. When it is determined that the mobile base station 20 is moving, the moving flag of the entry corresponding to the mobile base station 20 in the base station state table (for example, FIG. 7) is set. Furthermore, the base station management device 23 may notify the mobile base station 20 that it is in the “moving” state (step S65). Receiving this notification, the mobile base station 20 shifts to the moving state (step S66).
　図１３は、コアネットワーク１２から移動局１１に対する通信要求の制御シーケンスの一例を示している。ステップＳ７１～Ｓ７３は、移動基地局２０が移動中でない場合の制御シーケンスである。ステップＳ７１では、基地局管理装置２３は、コアネットワーク１２から通信要求を受信する。基地局管理装置２３は、受信した通信要求に含まれる宛て先移動局１１の端末ＩＤを用いて、宛て先移動局がどの基地局の配下にいるかを確認する。確認された基地局が他の基地局管理装置２３の管理下にある場合、基地局管理装置２３は他の基地局管理装置２３に通信要求を転送してもよい。ステップＳ７２では、基地局管理装置２３は、宛て先移動局１１が接続している移動基地局２０が移動中状態であるかを確認する。移動中状態でないことが確認できた場合、基地局管理装置２３は、移動基地局２０を経由して移動局１１に通信要求を転送する（ステップＳ７３）。 FIG. 13 shows an example of a communication request control sequence from the core network 12 to the mobile station 11. Steps S71 to S73 are a control sequence when the mobile base station 20 is not moving. In step S <b> 71, the base station management device 23 receives a communication request from the core network 12. The base station management device 23 uses the terminal ID of the destination mobile station 11 included in the received communication request to confirm which base station the destination mobile station is under. When the confirmed base station is under the management of another base station management device 23, the base station management device 23 may transfer a communication request to the other base station management device 23. In step S72, the base station management apparatus 23 checks whether the mobile base station 20 to which the destination mobile station 11 is connected is in a moving state. If it is confirmed that the mobile station is not in a moving state, the base station management device 23 transfers a communication request to the mobile station 11 via the mobile base station 20 (step S73).
　図１３のステップＳ７４～Ｓ７９は、移動基地局２０が移動中である場合の制御シーケンスである。ステップＳ７４では、基地局管理装置２３は、コアネットワーク１２から通信要求を受信する。ステップＳ７５では、基地局管理装置２３は、宛て先移動局１１が接続している移動基地局２０が移動中状態であるかを確認する。移動中状態であることが確認できた場合、基地局管理装置２３は、通信要求の送信元に通信不可を示すメッセージを送信する（ステップＳ７６）。また、基地局管理装置２３は、移動局１１に対して通信要求があったことを通知してもよい。 Steps S74 to S79 in FIG. 13 are control sequences when the mobile base station 20 is moving. In step S74, the base station management apparatus 23 receives a communication request from the core network 12. In step S75, the base station management apparatus 23 checks whether the mobile base station 20 to which the destination mobile station 11 is connected is in a moving state. When it is confirmed that the mobile device is in the moving state, the base station management device 23 transmits a message indicating that communication is not possible to the transmission source of the communication request (step S76). Further, the base station management device 23 may notify the mobile station 11 that a communication request has been made.
　さらに、基地局管理装置２３は、通信要求の種別を判定し、優先度の高い通信要求、又は許可しても問題ないと考えられる通信要求である場合には、移動基地局２０が移動中であっても、これを許可してもよい。例えば、受信した通信要求が予め定められた緊急通信要求である場合（ステップＳ７８）、移動基地局２０が移動中であっても、移動局１１に通信要求を転送してもよい（ステップＳ７９）。 Further, the base station management device 23 determines the type of communication request, and if the communication request is a high priority communication request or a communication request that can be permitted even if it is permitted, the mobile base station 20 is moving. You may allow this. For example, when the received communication request is a predetermined emergency communication request (step S78), the communication request may be transferred to the mobile station 11 even if the mobile base station 20 is moving (step S79). .
　図１４は、移動基地局２０に接続する移動局１１からの通信要求の制御シーケンスの一例を示している。ステップＳ８１～Ｓ８３は、移動基地局２０が移動中でない場合の制御シーケンスである。ステップＳ８１では、移動基地局２０は、移動局１１から通信要求を受信する。この通信要求は、移動基地局２０が移動中状態であるか否かを基地局管理装置２３に問い合わせるために、一旦移動基地局２０内部でバッファしてもよい。また、移動基地局２０は、基地局管理装置２３からの通知によって、予め自身が移動中か否かを確認しておいてもよい。ステップＳ８２では、移動基地局２０は、自身が移動中状態であるかを確認する。なお、ステップＳ８２に先立って、移動基地局２０は、現在コアネットワーク１２に繋がっているか否かを確認し、繋がっていない場合には通信不可を移動局１１へ返してもよい。自身が移動中状態でないことが確認できた場合、移動基地局２０は、コアネットワーク１２に通信要求を転送する（ステップＳ８３）。 FIG. 14 shows an example of a control sequence of a communication request from the mobile station 11 connected to the mobile base station 20. Steps S81 to S83 are a control sequence when the mobile base station 20 is not moving. In step S <b> 81, the mobile base station 20 receives a communication request from the mobile station 11. This communication request may be temporarily buffered in the mobile base station 20 in order to inquire the base station management apparatus 23 whether or not the mobile base station 20 is in a moving state. In addition, the mobile base station 20 may confirm beforehand whether or not it is moving based on a notification from the base station management device 23. In step S82, the mobile base station 20 confirms whether it is in a moving state. Prior to step S <b> 82, the mobile base station 20 may check whether or not the mobile base station 20 is currently connected to the core network 12. If it is confirmed that the mobile base station 20 is not in a moving state, the mobile base station 20 transfers a communication request to the core network 12 (step S83).
　図１４のステップＳ８４～Ｓ８６は、移動基地局２０が移動中である場合の制御シーケンスである。ステップＳ８４では、移動基地局２０は、移動局１１から通信要求を受信する。ステップＳ８５では、移動基地局２０は、自身が移動中状態であるかを確認する。自身が移動中状態であることが確認できた場合、移動基地局２０は、移動局１１に対して通信不可である旨を通知する（ステップＳ８６）。 14 is a control sequence when the mobile base station 20 is moving. In step S <b> 84, the mobile base station 20 receives a communication request from the mobile station 11. In step S85, the mobile base station 20 confirms whether it is in a moving state. If the mobile base station 20 can confirm that it is moving, the mobile base station 20 notifies the mobile station 11 that communication is not possible (step S86).

In the first and second embodiments of the present invention described above, it is possible to determine whether or not the mobile base station using the position determination information is moving by using another device (specifically, the base station) that is different from the mobile base station itself. The example which management apparatus 23 and 33) performs was shown. In the present embodiment, an example will be described in which the mobile base station itself determines whether or not it is moving using the position determination information.
　図１７は、本実施の形態にかかる移動通信システムに含まれる移動基地局４０の構成例を示すブロック図である。図１７の構成例では、図４に示した構成例に比べて、移動中判定部４０４が追加されている。移動中判定部４０４は、位置検出部２０２によって取得される位置判定情報を用いて、移動基地局４０が移動中であるか否かを判定する。移動中であるか否かを判定の判定手法の詳細は、実施の形態１～３で述べたのと同様とすればよい。移動中判定部４０４は、移動基地局４０が移動中であると判定した場合、移動中状態であることを基地局管理装置４３に通知する。 FIG. 17 is a block diagram showing a configuration example of the mobile base station 40 included in the mobile communication system according to the present embodiment. In the configuration example of FIG. 17, a moving determination unit 404 is added compared to the configuration example shown in FIG. The moving determination unit 404 uses the position determination information acquired by the position detection unit 202 to determine whether or not the mobile base station 40 is moving. The details of the determination method for determining whether or not the vehicle is moving may be the same as described in the first to third embodiments. When determining that the mobile base station 40 is moving, the moving determination unit 404 notifies the base station management device 43 that the mobile base station 40 is moving.
　図１８は、移動基地局４０が移動中か否かの判定を行う場合のシーケンスの一例を示している。ステップＳ１１１では、移動基地局４０は、自身の起動直後、またはハンドオーバを契機として初期値の位置登録を基地局管理装置４３に対して行う。ステップＳ１１２では、基地局管理装置４３は、移動基地局４０から基地局位置登録を受信し、位置履歴テーブル（例えば図６Ａ又は６Ｂ）における移動基地局４０に対応するエントリを更新する。ステップＳ１１３では、移動中判定部４０４によって自局が移動中であることを判定する。ステップＳ１１３で移動中であると判定した場合、移動基地局４０は、移動中である旨を示す通知を基地局管理装置４３に送る（ステップＳ１１4）。この通知には、移動基地局４０の最新の位置判定情報と基地局ＩＤを含めるとよい。基地局管理装置４３は、移動基地局４０からの通知に応じて、位置履歴テーブルの移動基地局４０に対応するエントリを更新するとともに、基地局状態テーブル（例えば図７）の移動基地局４０に対応するエントリの移動中フラグを設定する（ステップＳ１１５及びＳ１１６）。ステップＳ１１７では、移動基地局４０は移動中状態に移行する。 FIG. 18 shows an example of a sequence for determining whether or not the mobile base station 40 is moving. In step S111, the mobile base station 40 performs initial position registration with the base station management apparatus 43 immediately after starting itself or triggered by a handover. In step S112, the base station management apparatus 43 receives the base station location registration from the mobile base station 40, and updates the entry corresponding to the mobile base station 40 in the location history table (for example, FIG. 6A or 6B). In step S113, the moving determination unit 404 determines that the own station is moving. If it is determined in step S113 that the mobile base station 40 is moving, the mobile base station 40 sends a notification indicating that the mobile base station 40 is moving to the base station management apparatus 43 (step S114). This notification may include the latest position determination information of the mobile base station 40 and the base station ID. In response to the notification from the mobile base station 40, the base station management device 43 updates the entry corresponding to the mobile base station 40 in the location history table and also updates the mobile base station 40 in the base station state table (for example, FIG. 7). A moving flag for the corresponding entry is set (steps S115 and S116). In step S117, the mobile base station 40 shifts to a moving state.
　なお、本実施の形態における移動局１１の通信規制は、実施の形態１～３で述べたのと同様の手順によって、移動基地局４０若しくは基地局管理装置４３、又はこれら２装置の間で適宜分担して行えばよい。 Note that the communication restriction of the mobile station 11 in the present embodiment is appropriately determined between the mobile base station 40 or the base station management device 43 or these two devices by the same procedure as described in the first to third embodiments.

The LAN communication unit 504 acquires position determination information from an external system (such as a GPS receiver installed in the mobile device 80), and supplies this to the position detection unit 202.
＜発明の実施の形態６＞
　本実施の形態では、移動基地局の位置判定情報として、移動局１１が生成する位置登録要求に含まれる、移動局１１の位置に関する情報を利用する例について説明する。移動通信システムでは、移動局の位置をコアネットワーク側で管理するために、通常、移動局が定期的にコアネットワークに対して自身の位置に関する情報を通知する。例えば、移動局は、どの基地局に現在接続しており、さらにどのような周辺基地局の電波を同時に受信しているか、などの情報を送信する。 <Sixth Embodiment of the Invention>
In the present embodiment, an example will be described in which information regarding the position of the mobile station 11 included in the position registration request generated by the mobile station 11 is used as the position determination information of the mobile base station. In a mobile communication system, in order to manage the position of a mobile station on the core network side, usually, the mobile station periodically notifies the core network of information regarding its own position. For example, the mobile station transmits information such as which base station it is currently connected to, and what kind of peripheral base station it is receiving simultaneously.
　図２０は、本実施の形態にかかる移動通信システムに含まれる移動基地局６０の構成例を示すブロック図である。図２０と図４を比較すると、図２０の構成例は、位置検出部２０２に代えて、基地局情報追加部６０４を有する。基地局情報追加部６０４は、移動局１１から定期的に送信されてくる位置登録（位置更新）パケットに対して移動基地局６０の基地局ＩＤを追加する。基地局ＩＤを追加された位置登録（位置更新）パケットは、端末通信制御部２０３及びコア網通信部２０１を介してコアネットワーク１２に送られる。 FIG. 20 is a block diagram illustrating a configuration example of the mobile base station 60 included in the mobile communication system according to the present embodiment. 20 is compared with FIG. 4, the configuration example of FIG. 20 includes a base station information addition unit 604 instead of the position detection unit 202. The base station information adding unit 604 adds the base station ID of the mobile base station 60 to the position registration (position update) packet periodically transmitted from the mobile station 11. The location registration (location update) packet to which the base station ID is added is sent to the core network 12 via the terminal communication control unit 203 and the core network communication unit 201.
　図２１は、本実施の形態にかかる移動通信システムに含まれる基地局管理装置６３の構成例を示すブロック図である。図２０の構成例は、位置登録処理部６３５を含む。位置登録処理部６３５は、基地局ＩＤを追加された位置登録（位置更新）パケットを移動基地局６０から受信し、当該パケットに含まれる情報を用いて位置履歴テーブル（例えば図６Ａ又は６Ｂ）を更新する。さらに、位置登録処理部６３５は、位置登録（位置更新）パケットから基地局ＩＤを取り除いた後に、端末・ユーザ情報を管理するコアネットワーク１２内の装置（ＨＬＲ等）に転送する。 FIG. 21 is a block diagram showing a configuration example of the base station management device 63 included in the mobile communication system according to the present embodiment. The configuration example in FIG. 20 includes a location registration processing unit 635. The location registration processing unit 635 receives a location registration (location update) packet to which the base station ID has been added from the mobile base station 60, and uses the information included in the packet to store a location history table (for example, FIG. 6A or 6B). Update. Further, the location registration processing unit 635 removes the base station ID from the location registration (location update) packet, and then transfers it to a device (such as an HLR) in the core network 12 that manages terminal / user information.
　図２２は、移動基地局６０から基地局管理装置６３への位置判定情報の送信シーケンスの一例を示している。ステップＳ１２１では、移動局１１が位置登録パケットを送信する。位置登録パケットは、少なくとも、移動局１１の端末ＩＤ、及び移動局１１の位置に関する情報を含む。位置登録パケットは、通常、移動局１１から定期的に送信される。位置登録パケットは、コアネットワーク１２に転送され、移動局１１の位置管理に使用され、主に移動局１１に対する着呼時のページングに利用される。 FIG. 22 shows an example of a transmission sequence of position determination information from the mobile base station 60 to the base station management device 63. In step S121, the mobile station 11 transmits a location registration packet. The location registration packet includes at least information related to the terminal ID of the mobile station 11 and the location of the mobile station 11. The location registration packet is normally transmitted periodically from the mobile station 11. The location registration packet is transferred to the core network 12, used for location management of the mobile station 11, and mainly used for paging at the time of an incoming call to the mobile station 11.
　位置登録パケットを受信した移動基地局４０１は、これに自身の基地局ＩＤを付加して基地局管理装置６３に送信する（ステップＳ１２２）。ステップＳ１２３では、基地局管理装置６３は、移動基地局４０から受信した位置登録パケットに含まれる情報のうち、端末の位置に関する情報と基地局ＩＤを抽出し、位置履歴テーブルの移動基地局４０に対応するエントリを更新する。さらに基地局管理装置６３は、基地局ＩＤを含む位置登録パケットから基地局ＩＤを取り除くことによって、位置登録パケットのフォーマットをコアネットワーク１２に転送される通常のフォーマットに戻す。フォーマットを戻された位置登録パケットは、基地局管理装置６３からコアネットワーク１２へ送られる（ステップＳ１２４）。コアネットワーク１２は位置登録パケットを受信し、移動局１１の位置に関する情報を更新する。 The mobile base station 401 that has received the location registration packet adds its own base station ID to this and transmits it to the base station management device 63 (step S122). In step S123, the base station management device 63 extracts the information on the location of the terminal and the base station ID from the information included in the location registration packet received from the mobile base station 40, and stores it in the mobile base station 40 of the location history table. Update the corresponding entry. Further, the base station management apparatus 63 removes the base station ID from the location registration packet including the base station ID, thereby returning the format of the location registration packet to the normal format transferred to the core network 12. The location registration packet whose format has been returned is sent from the base station management apparatus 63 to the core network 12 (step S124). The core network 12 receives the location registration packet and updates information related to the location of the mobile station 11.
　本実施の形態によれば、移動基地局６０に位置検出のための装置（ＧＰＳ受信機等）を追加することなく、また、移動局１１によって生成される既存のパケットを利用して、移動基地局６０から基地局管理装置６３に位置判定情報を通知することができる。 According to the present embodiment, the mobile base station 60 does not add a device for position detection (such as a GPS receiver) and uses the existing packet generated by the mobile station 11 to The position determination information can be notified from the station 60 to the base station management device 63.
　さらに、本発明は上述した実施の形態のみに限定されるものではなく、既に述べた本発明の要旨を逸脱しない範囲において種々の変更が可能であることは勿論である。 Furthermore, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention already described.
