Description

本発明は、携帯電話機等の移動通信端末機が無線ＬＡＮ(Local Area Network)の構成要素である無線通信用のブロードバンドルータを介して通信を行うＶｏＩＰ(Voice over Internet Protocol)サービス提供時に、通信対象の移動通信端末機が在圏する単位料金区域の特定を可能とする無線ＬＡＮにおける単位料金区域特定システムに関する。 The present invention provides a communication target when a VoIP (Voice over Internet Protocol) service in which a mobile communication terminal such as a mobile phone communicates via a broadband router for wireless communication, which is a component of a wireless local area network (LAN). The present invention relates to a unit charge area specifying system in a wireless LAN that can specify a unit charge area in which a mobile communication terminal is located.

移動通信端末機が無線ＬＡＮの構成要素であるブロードバンドルータを介して通信を行う場合のＶｏＩＰサービス提供システムとして、例えば、特許文献１に記載のＶｏＩＰ認証システムがある。このシステムは、ネットワーク内にＳＩＰ(Session Initiation Protocol)サーバを配置し、このＳＩＰサーバに移動通信端末機等の端末機固有の認証データを予め登録しておく。そして、端末機がネットワーク機器を介してネットワークへ接続を試みる際に自己の認証データをＳＩＰサーバに対して送信すると、ネットワーク機器がＳＩＰサーバに対して上記認証データの中継を行い、ＳＩＰサーバが上記認証データを照合し、登録済みであるならば端末機に対して接続の許可を通知する。この通知に基づきネットワーク機器は、ＳＩＰサーバが接続を許可した認証済端末データを記憶し、この記憶に基づいて以後の端末の通信を許可するといった内容である。 As a VoIP service providing system when a mobile communication terminal communicates via a broadband router which is a component of a wireless LAN, for example, there is a VoIP authentication system described in Patent Document 1. In this system, a SIP (Session Initiation Protocol) server is arranged in a network, and authentication data specific to a terminal such as a mobile communication terminal is registered in advance in the SIP server. Then, when the terminal transmits its authentication data to the SIP server when attempting to connect to the network via the network device, the network device relays the authentication data to the SIP server, and the SIP server The authentication data is checked, and if it is registered, the terminal is notified of permission of connection. Based on this notification, the network device stores the authenticated terminal data that the SIP server has permitted to connect, and permits subsequent terminal communication based on this storage.

ところで通常、移動通信端末機は、携帯電話機に代表されるように、移動体通信システム、ＰＳＴＮ(Public Switched Telephone Networks)等で通信を行う。この場合の携帯電話機での音声通話時においては、発信側の交換機が加入者の料金明細情報を作成するための情報として着信網から取得した後述で説明する単位料金区域の情報｛ＣＡ(Charging Area)情報とも称す｝を取得するようになっている。交換機は、その取得したＣＡ情報を参照して適切なレートにて課金を行う。 By the way, a mobile communication terminal normally performs communication by a mobile communication system, PSTN (Public Switched Telephone Networks), etc., as represented by a mobile phone. In the case of a voice call on the mobile phone in this case, information on a unit charge area (CA (Charging Area), which will be described later, which is obtained from the incoming network as information for creating the charge detailed information of the subscriber by the exchange on the calling side. ) Is also called information}. The exchange refers to the acquired CA information and charges at an appropriate rate.

単位料金区域｛ＣＡ(Charging Area)｝とは、通常の市内・市外通話料金の区域とは別に定められる料金区域であり、発信側交換機の単位料金区域と着信側交換機の単位料金区域との関係で通話料金が決定される。通常は市外局番が同じであれば同一の単位料金区域となっており、この場合、同一市外局番同士の電話機であれば市内通話料金で通話ができる。 The unit charge area {CA (Charging Area)} is a charge area that is determined separately from the normal local / international call charge area, and includes the unit charge area of the originating exchange and the unit charge area of the terminating exchange. The call charge is determined by the relationship. Usually, if the area code is the same, the same unit charge area is used. In this case, if the telephones have the same area code, a call can be made at a local call charge.

しかし、単位料金区域は、市外局番が異なった区域に同一の単位料金区域を定めることもでき、この場合、市外局番が異なるにも係わらず市内通話料金で電話をかけることができる。
また、単位料金区域は、その単位料金区域に与えられた電気通信事業者共通の５桁の識別コード（例えば、東京：３２０００、横須賀：４６８００）で識別可能となっている。 However, as for the unit charge area, the same unit charge area can be defined in areas with different area codes. In this case, it is possible to make a call at a local call charge even though the area codes are different.
The unit charge area can be identified by a common 5-digit identification code (for example, Tokyo: 32000, Yokosuka: 46800) assigned to the unit charge area.

例えば、図３に示すように、発信側の携帯電話機１０が移動体通信網１１の発信側交換機１２及び着信側交換機１３を介して着信側の携帯電話機１４と通話を行う場合を想定する。移動体通信網１１においては、各交換機１２，１３が東京、横須賀など地域毎に設置されているので、移動通信端末機が使用する交換機の位置に対応するＣＡを特定することができるようになっている。従って、下記のようにＣＡを特定して課金サービスを行うことができる。 For example, as shown in FIG. 3, it is assumed that the mobile phone 10 on the outgoing call side makes a call with the mobile phone 14 on the incoming call side via the outgoing call exchange 12 and the incoming call exchange 13 of the mobile communication network 11. In the mobile communication network 11, since the exchanges 12 and 13 are installed in each region such as Tokyo and Yokosuka, the CA corresponding to the position of the exchange used by the mobile communication terminal can be specified. ing. Therefore, the billing service can be performed by specifying the CA as described below.

まず、発信側携帯電話機１０からの発信信号Ｓ１は、発信側交換機１２及び着信側交換機１３を介して着信側携帯電話機１４へ送信される。その発信信号Ｓ１を受信した着信側携帯電話機１４は発信応答信号Ｓ２を返信する。この発信応答信号Ｓ２は、着信側交換機１３へ送信され、ここで当該交換機１３が存在する単位料金区域の情報（ＣＡ情報）が発信応答信号Ｓ２に設定され、発信側交換機１２へ送信される。発信側交換機１２では、その発信応答信号Ｓ２に設定された着信側のＣＡ情報と、自交換機１２の発信側のＣＡ情報との関係で通話料金が決定されて発信側携帯電話機１０に課金が行われる。
特開２００５−２３６３９２号公報 First, the outgoing signal S 1 from the outgoing side mobile phone 10 is transmitted to the incoming side mobile phone 14 via the outgoing side switch 12 and the incoming side switch 13. The receiving side mobile phone 14 that has received the call signal S1 returns a call response signal S2. This outgoing response signal S2 is transmitted to the terminating side exchange 13, where information on the unit charge area (CA information) where the relevant exchange 13 exists is set in the outgoing response signal S2 and transmitted to the outgoing side exchange 12. In the calling side exchange 12, the call charge is determined based on the relationship between the CA information on the called side set in the outgoing response signal S2 and the CA information on the calling side of the own exchange 12, and the calling side mobile phone 10 is charged. Is called.

上述したように、移動通信端末機は移動体通信システムやＰＳＴＮにおいては、携帯電話機の単位料金区域を特定し、この区域で通信料を一定とする等の課金サービスを行うことが可能となる。
しかし、特許文献１では、ＶｏＩＰ認証時にＳＩＰサーバで端末機の認証データと予め登録された認証データとを照合し、ＯＫであれば該当端末機の認証済端末データを記憶して通信を許可するので、セキュリティレベルを向上させた通信が可能となるが、端末機が在圏する単位料金区域を特定し、この特定区域の通信料を一定とする等の課金サービスを行うことができないという問題がある。 As described above, in a mobile communication system or PSTN, a mobile communication terminal can specify a unit charge area of a mobile phone and perform a charging service such as making the communication charge constant in this area.
However, in Patent Document 1, the authentication data of the terminal and the authentication data registered in advance are collated by the SIP server at the time of VoIP authentication. If OK, the authenticated terminal data of the corresponding terminal is stored and communication is permitted. Therefore, communication with an improved security level is possible, but there is a problem that billing services such as specifying the unit charge area where the terminal is located and making the communication charge of this specific area constant cannot be performed. is there.

本発明は、このような課題に鑑みてなされたものであり、移動通信端末機が在圏する単位料金区域を特定し、この特定区域の通信料を一定とする等の課金サービスを行うことを可能とする無線ＬＡＮにおける単位料金区域特定システムを提供することを目的としている。 The present invention has been made in view of such a problem, and specifies a unit fee area where a mobile communication terminal is located and performs a charging service such as making the communication fee of this specific area constant. An object of the present invention is to provide a unit charge area specifying system in a wireless LAN that can be made possible.

上記目的を達成するために、本発明の請求項１による無線ＬＡＮにおける単位料金区域特定システムは、移動通信端末機が無線ＬＡＮ通信を行うルータの認証後に同ルータに任意のＩＰアドレスが割当てられた後、このルータの無線通信圏内に移動通信端末機が在圏した場合、当該移動通信端末機がルータを介して移動体通信網にアクセスし、この移動体通信網に配備された端末機認証用の認証サーバと、先に割当てられたＩＰアドレスをもとにルータを介してアクセスされる移動通信端末機の通信開始から終了までを制御するＳＩＰサーバと、このＳＩＰサーバから転送されてきた移動通信端末機の在圏登録要求に応じて要求元移動通信端末機の在圏登録処理を行う在圏管理サーバと連携して通信を行う無線ＬＡＮにおける単位料金区域特定システムにおいて、前記ルータは、自ルータの設置地域の単位料金区域情報が入力操作で設定保持された後、この単位料金区域情報を、ルータ認証用の認証要求信号に設定する入力設定手段を備え、前記認証サーバは、前記ルータの認証要求信号の受信時に、当該認証要求信号に設定された単位料金区域情報を保持する単位料金区域情報保持手段を備え、前記認証サーバは、前記移動通信端末機からの認証要求信号の受信時に、前記ルータを経由した通信であることを把握し、前記単位料金区域情報保持手段にて取得した単位料金区域情報を認証要求元の移動通信端末機の固有情報と共に前記在圏管理サーバへ通知する通知手段を備え、前記在圏管理サーバは、前記通知手段から通知された単位料金区域情報と認証要求元の移動通信端末機の固有情報とを対応付けて保持する保持手段と、前記ＳＩＰサーバから転送されてきた在圏登録信号の送信元の移動通信端末機と同じ固有情報が前記保持手段に保持されている際に、これら保持された固有情報及び単位料金区域情報を、前記ＳＩＰサーバへ返信される在圏登録応答信号に設定する設定手段とを備えたことを特徴とする。 In order to achieve the above object, according to claim 1 of the present invention, a unit charge area specifying system in a wireless LAN has an arbitrary IP address assigned to the router after the mobile communication terminal authenticates the router performing wireless LAN communication. Later, when a mobile communication terminal is located within the wireless communication range of the router, the mobile communication terminal accesses the mobile communication network via the router, and is used for authentication of the terminal deployed in the mobile communication network. Authentication server, a SIP server that controls from the start to the end of communication of a mobile communication terminal accessed via a router based on a previously assigned IP address, and mobile communication transferred from this SIP server Unit charge area characteristics in a wireless LAN that performs communication in cooperation with a location management server that performs location registration processing of a request source mobile communication terminal in response to a location registration request of a terminal In the system, the router includes input setting means for setting the unit charge area information in an authentication request signal for router authentication after the unit charge area information of the installation area of the router is set and held by an input operation. The authentication server includes unit fee area information holding means for holding unit fee area information set in the authentication request signal when the authentication request signal of the router is received, and the authentication server receives from the mobile communication terminal When receiving the authentication request signal, it is understood that the communication is via the router, and the unit fee area information acquired by the unit fee area information holding means is combined with the unique information of the mobile communication terminal that is the authentication request source. A notification means for notifying to the area management server, wherein the area management server includes the unit fee area information notified from the notification means and the mobile communication terminal of the authentication request source Holding means for associating and holding the unique information, and when the holding means holds the same unique information as the mobile communication terminal that is the transmission source of the location registration signal transferred from the SIP server, And setting means for setting the held unique information and unit fee area information in a location registration response signal returned to the SIP server.

この構成によれば、ルータに当該ルータの設置地域の単位料金区域情報を入力操作にて設定保持し、この保持した単位料金区域情報を、そのルータの認証時に認証サーバへ通知し、移動通信端末機の認証要求時に該当ルータを経由した通信である場合に該当ルータから通知された単位料金区域情報を認証サーバを介して在圏管理サーバへ保持し、更に同移動通信端末機の在圏登録要求時に在圏登録応答に設定してＳＩＰサーバへ返信するようにしたので、ＳＩＰサーバに単位料金区域情報を保持することができる。従って、ＳＩＰサーバに単位料金区域情報を保持後、移動通信端末機が通信相手へ発信を行えば、単位料金区域情報が保存されたＳＩＰサーバを介して相手の移動通信端末機へ着信が行われるので、通話双方の移動通信端末機が在圏する単位料金区域を特定することができ、この特定区域の通信料を一定とする等の課金サービスを行うことが可能となる。 According to this configuration, the unit fee area information of the installation area of the router is set and held in the router by the input operation, the held unit fee area information is notified to the authentication server at the time of authentication of the router, and the mobile communication terminal If the communication is via the router at the time of authentication request of the machine, the unit charge area information notified from the router is held in the area management server via the authentication server, and the area registration request for the mobile communication terminal Since it is sometimes set as a location registration response and sent back to the SIP server, the unit fee area information can be held in the SIP server. Accordingly, if the mobile communication terminal makes a call to the communication partner after holding the unit charge area information in the SIP server, the incoming call is made to the partner mobile communication terminal via the SIP server in which the unit charge area information is stored. Therefore, it is possible to specify the unit charge area where the mobile communication terminals for both calls are located, and to perform a charging service such as making the communication charge in this specific area constant.

ＢＢＲＴ２１は、本例のように宅内等にて携帯電話機２４をインターネットに接続するための無線通信機能を有するルータであり、ＢＢＲＴ電源立上げ時やＢＢＲＴ設定時に、認証サーバに向けてユーザＩＤ，パスワードを送信して認証処理を実施するようになっている。
また、ＢＢＲＴ２１のＣＡ入力設定部２１ａは、既に前述で説明したＣＡ情報である単位料金区域の識別コード（例えば、東京：３２０００、横須賀：４６８００…）の表（以降、ＣＡコード表と称す）を参照しながら、当該ＢＢＲＴ２１が設置されている地域のＣＡ情報を操作入力して設定保持できる処理機能と、認証サーバに対してＣＡ情報を通知する処理を行なうものである。 The BBRT 21 is a router having a wireless communication function for connecting the mobile phone 24 to the Internet at home or the like as in the present example. When the BBRT power is turned on or BBRT is set, a user ID and password are given to the authentication server. Is sent to perform the authentication process.
Further, the CA input setting unit 21a of the BBRT 21 uses a table (hereinafter referred to as a CA code table) of unit charge area identification codes (for example, Tokyo: 32000, Yokosuka: 46800...), Which has already been described above, as CA information. While referring to the processing function, the CA information of the area where the BBRT 21 is installed can be operated and set, and a process of notifying the authentication server of the CA information is performed.

認証サーバ３３は、ＢＢＲＴ２１からＣＡ情報を設定した認証要求信号受信を受信した際に、認証を行い、この結果を認証応答信号としてＢＢＲＴ２１へ返信する。その際、ＢＢＲＴとＣＡ情報を関連付けるデータを保持する。
携帯電話機２４からの認証要求信号を受信した際に、認証を行い、この結果を認証応答信号として携帯電話機２４へ返信する。その際、携帯電話機２４が経由してきたＢＢＲＴを送信元ＩＰアドレス等の情報により、特定し、携帯電話機２４とＣＡ情報の関連付けを行なう。また、ＣＡ通知部３３ａによって認証要求信号中のＣＡ情報を認証要求元携帯電話機２４の固有情報と共に在圏管理サーバ３５へ通知する。 When the authentication server 33 receives the authentication request signal reception in which the CA information is set from the BBRT 21, the authentication server 33 performs authentication, and returns the result as an authentication response signal to the BBRT 21. At this time, data for associating BBRT with CA information is held.
When an authentication request signal is received from the mobile phone 24, authentication is performed and the result is returned to the mobile phone 24 as an authentication response signal. At that time, the BBRT through which the mobile phone 24 has passed is specified by information such as the source IP address, and the mobile phone 24 is associated with the CA information. Also, the CA notification unit 33a notifies the CA management server 35 of the CA information in the authentication request signal together with the unique information of the authentication request source mobile phone 24.

在圏管理サーバ３５は、認証サーバ３３から通知されたＣＡ情報を認証要求元携帯電話機２４の固有情報と共にＣＡ保持部３５ａに保持する。
また、在圏管理サーバ３５は、在圏登録処理時にＳＩＰサーバ３４から転送されてきた在圏登録信号をもとに、当該在圏登録信号の送信元携帯電話機２４がどのＳＩＰサーバ３４配下に在圏するかを保持したのち、在圏登録が完了したことを送信元携帯電話機２４の加入者情報を含めて在圏登録応答として、在圏登録信号を転送してきたＳＩＰサーバ３４へ返信する。 The located area management server 35 holds the CA information notified from the authentication server 33 in the CA holding unit 35 a together with the unique information of the authentication request source mobile phone 24.
In addition, based on the location registration signal transferred from the SIP server 34 during the location registration process, the location management server 35 is located under which SIP server 34 the source mobile phone 24 of the location registration signal is located. After holding whether or not the user is in the service area, the fact that the service area registration has been completed is returned to the SIP server 34 that has transferred the service area registration signal as a service area registration response including the subscriber information of the source mobile phone 24.

更に、在圏管理サーバ３５は、受信した在圏登録信号の送信元携帯電話機２４の固有情報がＣＡ保持部３５ａに保持されている場合、その固有情報と共に保持されているＣＡ情報を、ＣＡ設定部３５ｂによって在圏登録応答に設定する。
ＳＩＰサーバ３４は、携帯電話機の通信時の開始から完了までを制御するサーバであり、在圏管理サーバ３５からの在圏登録応答に含まれる加入者情報並びにＣＡ情報を保持する。 Further, when the unique information of the mobile phone 24 that is the transmission source of the received registered registration signal is held in the CA holding unit 35a, the located area management server 35 sets the CA information held together with the unique information to the CA setting. It is set to the in-zone registration response by the unit 35b.
The SIP server 34 is a server that controls from the start to the completion of communication of the mobile phone, and holds subscriber information and CA information included in the location registration response from the location management server 35.

このような構成の無線ＬＡＮにおける単位料金区域特定システム２０において、無線ＬＡＮ利用の携帯電話機が在圏する単位料金区域の特定動作を、図２に示すシーケンス図を参照して説明する。
まず、ステップＳ１において、ＢＢＲＴ２１の利用者が、ＣＡ入力設定部２１ａにて、ＣＡコード表を参照しながら当該ＢＢＲＴ２１の設置地域（例えば東京のＣＡ情報（３２０００）を操作入力して設定したとする。 With reference to the sequence diagram shown in FIG. 2, description will be given of the operation of identifying the unit fee area in which the mobile phone using the wireless LAN is located in the unit fee area identifying system 20 in the wireless LAN having such a configuration.
First, in step S1, it is assumed that the user of the BBRT 21 operates the CA input setting unit 21a by operating and setting the installation area of the BBRT 21 (for example, CA information (32000) in Tokyo) while referring to the CA code table. .

その後、ＢＢＲＴ２３はステップＳ２並びにステップＳ３において、ＣＡ情報を設定した認証要求信号を認証サーバ３３へ送信したとする。
認証サーバ３３はステップＳ４において認証処理を実施し、その際、ステップＳ５にてＢＢＲＴとＣＡ情報を関連付けるデータを保持する。
その後、携帯電話機２４がＢＢＲＴ２１の無線通信圏内、即ち無線ＬＡＮ圏内に在圏し、ステップＳ７において、自機認証のために認証要求信号をＢＢＲＴ２１を介して認証サーバ３３へ送信したとする。 Thereafter, it is assumed that the BBRT 23 transmits an authentication request signal in which CA information is set to the authentication server 33 in steps S2 and S3.
The authentication server 33 performs an authentication process in step S4, and holds data that associates BBRT and CA information in step S5.
Thereafter, it is assumed that the mobile phone 24 is in the wireless communication area of the BBRT 21, that is, in the wireless LAN area, and transmits an authentication request signal to the authentication server 33 via the BBRT 21 in step S 7 for self-machine authentication.

この認証要求信号を受信した認証サーバ３３は、ステップＳ８において、認証要求元携帯電話機２４の認証を行い、この認証がＯＫであれば、ステップＳ１０において、その携帯電話機２４へ認証ＯＫの応答を返信する。その際、認証サーバはステップ９にて携帯電話機２４が使用しているＢＢＲＴ２１をＩＰアドレス等により特定し、先に保持しているＣＡ情報と携帯電話機２４との関連付けを行なう。更に、認証サーバ３３は、ステップＳ１１において、ＣＡ通知部３３ａによってＣＡ情報を認証要求元携帯電話機２４の固有情報と共に在圏管理サーバ３５へ通知する。 Upon receiving this authentication request signal, the authentication server 33 authenticates the authentication request source mobile phone 24 in step S8, and if this authentication is OK, returns an authentication OK response to the mobile phone 24 in step S10. To do. At that time, the authentication server specifies the BBRT 21 used by the mobile phone 24 by the IP address or the like in step 9 and associates the CA information previously held with the mobile phone 24. Further, in step S11, the authentication server 33 notifies the CA management unit 35 of the CA information together with the unique information of the authentication request source mobile phone 24 by the CA notification unit 33a.

この通知を受けた在圏管理サーバ３５は、ステップＳ１２において、認証サーバ３３から通知されたＣＡ情報を認証要求元携帯電話機２４の固有情報と共にＣＡ保持部３５ａに保持する。
一方、上記にて認証が行われた携帯電話機２４は、ステップＳ１３において、在圏登録信号をＢＢＲＴ２１を介して、既に割当てられたアドレスのＳＩＰサーバ３４へ送信し、これを受信したＳＩＰサーバ３４が、ステップＳ１４において、その在圏登録信号を在圏管理サーバ３５へ転送する。 Upon receiving this notification, the located area management server 35 holds the CA information notified from the authentication server 33 in the CA holding unit 35a together with the unique information of the authentication request source mobile phone 24 in step S12.
On the other hand, in step S13, the mobile phone 24 that has been authenticated transmits a location registration signal to the SIP server 34 at the already assigned address via the BBRT 21, and the SIP server 34 that has received this signal transmits it. In step S14, the location registration signal is transferred to the location management server 35.

これを受信した在圏管理サーバ３５は、ステップＳ１５において、携帯電話機２４がどのＳＩＰサーバ配下に在圏したかを保持する。ここで、在圏登録が完了したことを、登録加入者情報を含めて在圏登録応答としてＳＩＰサーバ３４へ返信するが、この際、ステップＳ１６において、在圏管理サーバ３５は、受信在圏登録信号の送信元携帯電話機２４の固有情報がＣＡ保持部３５ａに保持されている場合、その固有情報と共に保持されているＣＡ情報を在圏登録応答に設定する。 Having received this, the located area management server 35 holds in which SIP server the mobile phone 24 is located. Here, the fact that the area registration has been completed is returned to the SIP server 34 as the area registration response including the registered subscriber information. At this time, the area management server 35 receives the area registration in step S16. When the unique information of the signal source mobile phone 24 is held in the CA holding unit 35a, the CA information held together with the unique information is set in the in-zone registration response.

そして、ステップＳ１７において、加入者情報及びＣＡ情報を含む在圏登録応答信号をＳＩＰサーバ３４へ返信する。
これを受けたＳＩＰサーバ３４は、ステップＳ１８において、在圏登録応答信号中の加入者情報とＣＡ情報とを対応付けて保持した後、ステップＳ１９において、在圏登録の完了を示す在圏登録応答をＢＢＲＴ２１を介して該当携帯電話機２４へ返信する。 In step S17, a location registration response signal including subscriber information and CA information is returned to the SIP server 34.
In response to this, the SIP server 34 retains the subscriber information and the CA information in the location registration response signal in association with each other in step S18, and then in step S19 indicates the location registration response indicating completion of the location registration. Is returned to the mobile phone 24 via the BBRT 21.

この在圏登録応答を受信した携帯電話機２４が、ステップＳ２０において図示せぬ相手側の携帯電話機へ通話発信を行うと、既に割当てられたアドレスのＳＩＰサーバ３４を介して相手側の携帯電話機へ着信されるようになる。
このように、本実施の形態の無線ＬＡＮにおける単位料金区域特定システム２０によれば、ＢＢＲＴ２１において自ＢＢＲＴ２１の設置地域のＣＡ情報を、ＣＡ入力設定部２１ａに入力操作で設定保持し、この保持されたＣＡ情報を、ＢＢＲＴ２１の認証要求信号に設定し、認証サーバ３３へ送信される。 When the mobile phone 24 that has received the location registration response makes a call to the other party's mobile phone (not shown) in step S20, the incoming call arrives at the other party's mobile phone via the SIP server 34 of the already assigned address. Will come to be.
As described above, according to the unit charge area specifying system 20 in the wireless LAN of the present embodiment, the CA information of the installation area of the own BBRT 21 is set and held in the CA input setting unit 21a by the BBRT 21, and is held. The CA information is set in the authentication request signal of the BBRT 21 and transmitted to the authentication server 33.

認証サーバ３３は、その認証要求信号の受信時に、ＢＢＲＴとＣＡ情報の関連付けデータを保持する。
その後、認証サーバ３３は、携帯電話機２４からの認証要求受信時に、携帯電話機２４が使用しているＢＢＲＴを特定し、ＣＡ情報と携帯電話機の関連付けを行なう。その後、ＣＡ通知部３３ａによって、ＣＡ情報を認証要求元の携帯電話機２４の固有情報と共に在圏管理サーバ３５へ通知する。 The authentication server 33 holds association data of BBRT and CA information when receiving the authentication request signal.
After that, when receiving an authentication request from the mobile phone 24, the authentication server 33 identifies the BBRT used by the mobile phone 24 and associates the CA information with the mobile phone. Thereafter, the CA notification unit 33a notifies the CA management information to the location management server 35 together with the specific information of the mobile phone 24 as the authentication request source.

在圏管理サーバ３５は、その通知されたＣＡ情報と認証要求元の携帯電話機２４の固有情報とを対応付けてＣＡ保持部３５ａに保持し、また、ＳＩＰサーバ３４から転送されてきた在圏登録信号の送信元の携帯電話機２４と同じ固有情報がＣＡ保持部３５ａに保持されている場合に、ＣＡ設定部３５ｂによって、それら保持された固有情報及びＣＡ情報を、ＳＩＰサーバ３４へ返信される在圏登録応答信号に設定するようにした。 The located area management server 35 associates the notified CA information with the unique information of the mobile phone 24 that is the authentication request source and retains it in the CA retaining unit 35 a, and also resides the area registration transferred from the SIP server 34. When the same unique information as the signal transmitting mobile phone 24 is held in the CA holding unit 35a, the CA setting unit 35b returns the held unique information and CA information to the SIP server 34. The zone registration response signal is set.

つまり、ＢＢＲＴ２１に当該ＢＢＲＴ２１の設置地域のＣＡ情報を入力操作にて設定保持し、この保持したＣＡ情報を、ＢＢＲＴ２１の認証時に認証サーバへ通知し、そのＢＢＲＴ２１を介した携帯電話機２４の認証要求時に認証サーバ３３を介して在圏管理サーバ３５へ保持し、更に同携帯電話機２４の在圏登録要求時に在圏登録応答に設定してＳＩＰサーバ３４へ返信する。これによってＳＩＰサーバ３４にＣＡ情報を保持し、携帯電話機２４が通話発信時にＳＩＰサーバ３４を介すことにより通話時の単位料金区域の特定を可能としたので、特定区域の通信料を一定とする等の課金サービスを行うことが可能となる。 In other words, the CA information of the BBRT 21 installation area is set and held in the BBRT 21 by an input operation, and the held CA information is notified to the authentication server when the BBRT 21 is authenticated, and when the authentication of the mobile phone 24 via the BBRT 21 is requested. The information is held in the location management server 35 via the authentication server 33, and is further set as a location registration response at the time of the location registration request of the mobile phone 24 and sent back to the SIP server 34. As a result, the CA information is held in the SIP server 34, and the mobile phone 24 can specify the unit charge area at the time of calling through the SIP server 34 at the time of calling, so the communication charge in the specific area is fixed. It is possible to provide a billing service.
