Description

本発明は、インフラストラクチャモードとアドホックモードを同時に利用できる無線通信装置において、アクセスポイント（ＡＰ）に接続できない非接続無線局とＡＰとの接続を可能にする無線通信装置に関する。   The present invention relates to a wireless communication apparatus that enables connection between an AP and an unconnected wireless station that cannot be connected to an access point (AP) in a wireless communication apparatus that can simultaneously use an infrastructure mode and an ad hoc mode.

無線パケット通信は、無線ＬＡＮをはじめとする様々なシステムで採用されている通信形態である。無線ＬＡＮの規格については、IEEE802.11委員会で標準化が進められ、IEEE802.11規格（非特許文献１）として制定されている。この規格では、２つの通信モード（インフラストラクチャモード、アドホックモード）が規定されている。   The wireless packet communication is a communication form adopted in various systems including a wireless LAN. The wireless LAN standard is being standardized by the IEEE802.11 committee and established as the IEEE802.11 standard (Non-Patent Document 1). In this standard, two communication modes (infrastructure mode and ad hoc mode) are defined.

インフラストラクチャモードは、ＡＰと、その電波到達範囲（無線セル）内に存在する端末局で構成され、ＡＰとその配下の端末局が無線媒体を介して接続関係を形成した無線ネットワークで使用される通信モードである。ＡＰは、イーサネット（登録商標）等のネットワークに接続されており、接続関係を確立している配下の端末局がネットワークと通信する際に、ネットワークと端末局間のパケットの中継を行う。すなわち、端末局からみたとき、ＡＰはネットワークへの入り口としての役割を担う。   The infrastructure mode is composed of an AP and a terminal station existing within the radio wave coverage (wireless cell), and is used in a wireless network in which the AP and a terminal station under the AP form a connection relationship via a wireless medium. Communication mode. The AP is connected to a network such as Ethernet (registered trademark), and relays packets between the network and the terminal station when a subordinate terminal station that establishes a connection relationship communicates with the network. That is, when viewed from the terminal station, the AP plays a role as an entrance to the network.

アドホックモードは、ＡＰを必要とせず、端末局のみにより構成されるクローズドネットワークで使用される通信モードである。端末局は、一般に無線パケットを中継する機能をもたず、直接互いに無線パケットをやりとりして通信を行う。   The ad hoc mode is a communication mode used in a closed network that does not require an AP and includes only terminal stations. Terminal stations generally do not have a function of relaying wireless packets, and directly communicate with each other by exchanging wireless packets.

また、セキュリティに関しては、IEEE802.11ｉ規格（非特許文献２，非特許文献３）として制定されている。この規格では、IEEE802.1xの認証技術を用いて、認証サーバで端末局の情報を管理し、認証を行う。すなわち、ＡＰは端末局から無線ＬＡＮ経由でアクセスがあった場合、当該端末局の正当性を認証サーバで確認してから、当該端末局をネットワークに接続する処理を行う。
IEEE802.11, "Wireless LAN Medium Access Control (MAC) and Physical (PHY) Layer Specifications", August 1999 改訂版802.11高速無線ＬＡＮ教科書, インプレス IEEE802.11, "Part 11:Wireless LAN Medium Access Control (MAC) and Physical (PHY) Layer Specifications, Amendment 6: Media Access Control (MAC) Security Enhancements", July 2004 Regarding security, it is established as the IEEE802.11i standard (Non-Patent Document 2, Non-Patent Document 3). In this standard, authentication information of IEEE802.1x is used to manage terminal station information by an authentication server and perform authentication. That is, when an access is made from a terminal station via a wireless LAN, the AP confirms the legitimacy of the terminal station with an authentication server, and then performs processing for connecting the terminal station to the network.
IEEE802.11, "Wireless LAN Medium Access Control (MAC) and Physical (PHY) Layer Specifications", August 1999 Revised 802.11 high-speed wireless LAN textbook, Impress IEEE802.11, "Part 11: Wireless LAN Medium Access Control (MAC) and Physical (PHY) Layer Specifications, Amendment 6: Media Access Control (MAC) Security Enhancements", July 2004

端末局が無線ＬＡＮ経由でネットワークに接続する場合には、ＡＰでネットワーク側の認証サーバによる認証が必要である。したがって、アドホックモードのみに対応してＡＰおよびネットワークへの接続を想定していない端末局や、ネットワーク側の認証サーバに登録されていない端末局がネットワークに接続するためには、予め認証サーバに端末局の情報を登録しておく必要があり、煩雑であった。そのため、ＡＰに接続できない（接続を想定していない）非接続無線局が一時的にネットワークに接続する場合には、認証サーバへ登録をすることなく、簡単にネットワークへの接続が可能になる方法が求められている。   When a terminal station connects to a network via a wireless LAN, authentication by an authentication server on the network side is required at the AP. Therefore, in order for a terminal station that is not supposed to be connected to the AP and the network corresponding to only the ad hoc mode, or a terminal station that is not registered in the authentication server on the network side to connect to the network, the terminal is previously connected to the authentication server. It was necessary to register station information, which was complicated. Therefore, when an unconnected wireless station that cannot connect to the AP (not assumed to be connected) temporarily connects to the network, it is possible to easily connect to the network without registering with the authentication server. Is required.

本発明は、インフラストラクチャーモードとアドホックモードの２つのモードを同時に利用でき、かつネットワークの認証サーバで認証済みの無線通信装置において、ＡＰに接続できないまたは認証サーバに未登録の非接続無線局とネットワークとの接続を可能にする無線通信装置を提供することを目的とする。   In the present invention, an unconnected wireless station and a network that cannot use an infrastructure mode and an ad hoc mode at the same time and cannot connect to an AP or are not registered in an authentication server in a wireless communication device that has been authenticated by a network authentication server It is an object of the present invention to provide a wireless communication device that enables connection with a wireless communication device.

本発明の無線通信装置は、アクセスポイントに接続するためのインフラストラクチャモードと、他の無線通信装置と通信するためのアドホックモードに対応する機能を有し、この２つのモードでアクセスポイントおよび他の無線通信装置と接続し、その間で送受信されるパケットの転送を行う転送手段と、アクセスポイントに接続できない非接続無線局からアドホックモードで送信されたパケットを受信し、そのパケットの送信元アドレスが規定のものであるか否かを検証し、規定の送信元アドレスであれば転送手段における転送処理を指示し、それ以外のパケットを破棄する制御を行う制御手段とを備える。   The wireless communication apparatus of the present invention has a function corresponding to an infrastructure mode for connecting to an access point and an ad hoc mode for communicating with another wireless communication apparatus. In these two modes, the access point and other Transfer means for transferring packets sent and received between wireless communication devices, and packets sent in ad hoc mode from unconnected wireless stations that cannot connect to the access point, and the source address of the packet is specified And control means for instructing transfer processing in the transfer means if it is a specified source address and controlling to discard other packets.

また、本発明の無線通信装置は、アクセスポイントを介して接続されるネットワークの認証サーバによる認証済みであり、非接続無線局に対して認証サーバに代わって制御手段が該ネットワークへの接続認証を行う構成である。   In addition, the wireless communication apparatus of the present invention has been authenticated by the authentication server of the network connected via the access point, and the control means authenticates the connection to the network for the unconnected wireless station instead of the authentication server. It is the structure to perform.

本発明によれば、ＡＰに接続できない非接続無線局は、インフラストラクチャモードとアドホックモードの２つのモードを利用できる無線通信装置を介することにより、ネットワークに接続することができる。また、この無線通信装置において、非接続無線局からアドホックモードで送信されたパケットの送信元アドレスを用いてフィルタリングを行うことにより、指定する非接続無線局のみをネットワークに接続させることができる。   According to the present invention, an unconnected wireless station that cannot connect to an AP can be connected to a network via a wireless communication device that can use two modes, an infrastructure mode and an ad hoc mode. Further, in this wireless communication apparatus, by performing filtering using the transmission source address of the packet transmitted from the unconnected wireless station in the ad hoc mode, only the specified unconnected wireless station can be connected to the network.

また、認証済みの無線通信装置がパケットの転送機能とフィルタリング機能をもつことにより、第三者が不正にネットワークに接続することを防止でき、認証の役割を果たすことができる。また、認証サーバではなく認証済みの無線通信装置が転送するパケットを選択するため、認証サーバへの登録に比べて設定が容易であり、一時的かつ迅速に認証サーバに未登録の端末局をネットワークに接続させることができる。   Further, since the authenticated wireless communication apparatus has a packet transfer function and a filtering function, it is possible to prevent a third party from illegally connecting to the network and to play a role of authentication. In addition, since the authenticated wireless communication device selects the packet to be transferred instead of the authentication server, it is easier to set up than the registration to the authentication server. Can be connected to.

図１は、本発明の無線通信装置を含む無線ＬＡＮシステムの構成例を示す。
図において、ＡＰ（アクセスポイント）１は、イーサネット等で構成されるネットワーク２に接続され、さらにネットワーク２には認証サーバ３が接続される。本発明の無線通信装置４は、その情報が認証サーバ３に登録済みになっているとともに、インフラストラクチャモードとアドホックモードの２つのモードを同時に利用できる構成になっている。すなわち、無線通信装置４は、インフラストラクチャモードでＡＰ１に接続し、ＡＰ１においてネットワーク２の認証サーバ３から認証後にネットワーク２に接続される。 FIG. 1 shows a configuration example of a wireless LAN system including a wireless communication apparatus of the present invention.
In the figure, an AP (access point) 1 is connected to a network 2 constituted by Ethernet or the like, and an authentication server 3 is further connected to the network 2. The wireless communication device 4 of the present invention is configured such that the information is already registered in the authentication server 3 and that two modes of the infrastructure mode and the ad hoc mode can be used simultaneously. That is, the wireless communication device 4 is connected to the AP 1 in the infrastructure mode, and is connected to the network 2 after being authenticated by the authentication server 3 of the network 2 in the AP 1.

一方、認証サーバ３に未登録あるいはインフラストラクチャモードに対応していないためにＡＰ１に直接接続できない非接続無線局（ＳＴＡ）５は、アドホックモードで認証済みの無線通信装置４に接続される。無線通信装置４は、アドホックモードでＳＴＡ５から送信されたパケットを受信すると同時にインフラストラクチャモードでＡＰ１と接続し、ＳＴＡ５とＡＰ１との間で送受信されるパケットを転送する機能を有する。   On the other hand, an unconnected radio station (STA) 5 that is not registered in the authentication server 3 or does not support the infrastructure mode and cannot be directly connected to the AP 1 is connected to the radio communication device 4 that has been authenticated in the ad hoc mode. The wireless communication device 4 has a function of receiving a packet transmitted from the STA 5 in the ad hoc mode and simultaneously connecting to the AP 1 in the infrastructure mode and transferring a packet transmitted / received between the STA 5 and the AP 1.

図２は、本発明の無線通信装置４の構成例を示す。
図において、無線通信装置４は、アンテナ１１と、アンテナ１１に接続される送受信部（ＴＲＸ）１２と、送受信部１２に順次接続されるベースバンド処理部（ＢＢ）１３、制御部（ＣＮＴ）１４、インタフェース部（Ｉ／Ｆ）１５により構成され、制御部１４ではインフラストラクチャモードとアドホックモードの２つのモードによる制御が行われる。 FIG. 2 shows a configuration example of the wireless communication device 4 of the present invention.
In the figure, a wireless communication device 4 includes an antenna 11, a transmission / reception unit (TRX) 12 connected to the antenna 11, a baseband processing unit (BB) 13 and a control unit (CNT) 14 sequentially connected to the transmission / reception unit 12. The interface unit (I / F) 15 is configured, and the control unit 14 performs control in two modes, an infrastructure mode and an ad hoc mode.

図３は、無線通信装置４を介してＳＴＡ５とＡＰ１との間で送受信されるパケットのアドレスフィールドの利用例を示す。ここでは、図３に示すように、ＳＴＡ５のＭＡＣアドレスを“111xxx”、ＩＰアドレスを“1.1.1.1 ”とし、無線通信装置４のＭＡＣアドレスを“011xxx”、ＩＰアドレスを“1.1.1.2 ”および“10.10.10.20 ”とし、ＡＰ１のＭＡＣアドレスを“001xxx”とし、ネットワーク２上にあってＳＴＡ５に対する宛先装置６のＭＡＣアドレスを“000xxx”、ＩＰアドレスを“10.10.10.1”とする。また、ＳＴＡ５と無線通信装置４との間のアドホックネットワークの識別子ＩＢＢＳＩＤを“123xxx”とする。   FIG. 3 shows a usage example of an address field of a packet transmitted / received between the STA 5 and the AP 1 via the wireless communication device 4. Here, as shown in FIG. 3, the MAC address of the STA 5 is “111xxx”, the IP address is “1.1.1.1”, the MAC address of the wireless communication device 4 is “011xxx”, the IP address is “1.1.1.2”, and “10.10.10.20”, the MAC address of AP1 is “001xxx”, the MAC address of the destination device 6 on the network 2 for the STA5 is “000xxx”, and the IP address is “10.10.10.1”. Further, the identifier IBBSID of the ad hoc network between the STA 5 and the wireless communication device 4 is “123xxx”.

図３(1) は、アドホックモードでＳＴＡ５から無線通信装置４へ送信されるパケットのアドレスフィールドの利用例を示す。パケットのＭＡＣアドレス１，２，３には、それぞれ宛先アドレス（無線通信装置４のＭＡＣアドレス）、送信元アドレス（ＳＴＡ５のＭＡＣアドレス）、ＩＢＳＳＩＤが設定される。また、ＩＰアドレス１，２には、それぞれパケットの宛先アドレス（宛先装置６のＩＰアドレス）、送信元アドレス（ＳＴＡ５のＩＰアドレス）が設定される。   FIG. 3 (1) shows an example of using the address field of a packet transmitted from the STA 5 to the wireless communication device 4 in the ad hoc mode. In the MAC addresses 1, 2 and 3 of the packet, a destination address (MAC address of the wireless communication device 4), a source address (MAC address of the STA 5), and IBSSID are set, respectively. The IP addresses 1 and 2 are set with the destination address of the packet (IP address of the destination device 6) and the source address (IP address of the STA 5), respectively.

図３(2) は、インフラストラクチャモードで無線通信装置４からＡＰ１へ送信されるパケットのアドレスフィールドの利用例を示す。パケットのＭＡＣアドレス１，２，３には、それぞれＢＳＳＩＤ（ＡＰ１のＭＡＣアドレス）、送信元アドレス（無線通信装置４のＭＡＣアドレス）、宛先アドレス（宛先装置６のＭＡＣアドレス）が設定される。また、ＩＰアドレス１，２には、それぞれパケットの宛先アドレス（宛先装置６のＩＰアドレス）、送信元アドレス（無線通信装置４のＩＰアドレス）が設定される。ただし、無線通信装置４では、アドホックモードにおけるＩＰアドレス“1.1.1.2 ”を“10.10.10.20 ”にＮＡＴ変換し、インフラストラクチャモードで送信するパケットを構成する。   FIG. 3 (2) shows an example of using an address field of a packet transmitted from the wireless communication apparatus 4 to the AP 1 in the infrastructure mode. The BSSID (the MAC address of AP1), the transmission source address (the MAC address of the wireless communication device 4), and the destination address (the MAC address of the destination device 6) are set in the MAC addresses 1, 2, and 3 of the packet, respectively. The IP addresses 1 and 2 are set with the destination address of the packet (IP address of the destination device 6) and the source address (IP address of the wireless communication device 4), respectively. However, in the wireless communication device 4, the IP address “1.1.1.2” in the ad hoc mode is NAT-converted to “10.10.10.20”, and a packet to be transmitted in the infrastructure mode is configured.

図３(3) は、インフラストラクチャモードでＡＰ１から無線通信装置４へ送信されるパケットのアドレスフィールドの利用例を示す。パケットのＭＡＣアドレス１，２，３には、それぞれ宛先アドレス（無線通信装置４のＭＡＣアドレス）、ＢＳＳＩＤ（ＡＰ１のＭＡＣアドレス）、送信元アドレス（宛先装置６のＭＡＣアドレス）が設定される。また、ＩＰアドレス１，２には、それぞれパケットの宛先アドレス（無線通信装置４のＩＰアドレス）、送信元アドレス（宛先装置６のＩＰアドレス）が設定される。   FIG. 3 (3) shows an example of using an address field of a packet transmitted from the AP 1 to the wireless communication device 4 in the infrastructure mode. In the MAC addresses 1, 2, and 3 of the packet, a destination address (MAC address of the wireless communication device 4), BSSID (MAC address of AP1), and source address (MAC address of the destination device 6) are set, respectively. The IP addresses 1 and 2 are set with the destination address of the packet (IP address of the wireless communication device 4) and the source address (IP address of the destination device 6), respectively.

図３(4) は、アドホックモードで無線通信装置４からＳＴＡ５へ送信されるパケットのアドレスフィールドの利用例を示す。パケットのＭＡＣアドレス１，２，３には、それぞれ宛先アドレス（ＳＴＡ５のＭＡＣアドレス）、送信元アドレス（無線通信装置４のＭＡＣアドレス）、ＩＢＳＳＩＤが設定される。また、ＩＰアドレス１，２には、それぞれパケットの宛先アドレス（ＳＴＡ５のＩＰアドレス）、送信元アドレス（宛先装置６のＩＰアドレス）が設定される。   FIG. 3 (4) shows an example of use of the address field of a packet transmitted from the wireless communication apparatus 4 to the STA 5 in the ad hoc mode. A destination address (MAC address of the STA 5), a source address (MAC address of the wireless communication device 4), and an IBSSID are set in the MAC addresses 1, 2, and 3 of the packet, respectively. The IP addresses 1 and 2 are set with the destination address of the packet (the IP address of the STA 5) and the source address (the IP address of the destination device 6), respectively.

このようなアドレス操作を行うことにより、ＳＴＡ５とＡＰ１との間で無線通信装置４を中継局としてパケットの送受信を行うことができる。   By performing such an address operation, packets can be transmitted and received between the STA 5 and the AP 1 using the wireless communication device 4 as a relay station.

ここで、中継局として機能する本発明の無線通信装置４の制御部１４は、中継するパケットの選択制御を行うフィルタリング機能を有する。そのフィルタリング機能による転送フィルタテーブルの一例を図４に示す。ここでは、ＳＴＡ５の送信元アドレス（ＭＡＣアドレス“111xxx”またはＩＰアドレス“1.1.1.1 ”）を有するパケットのみをＡＰ１に転送し、他の送信元アドレスを有するパケットを破棄する設定例を示す。   Here, the control unit 14 of the wireless communication apparatus 4 of the present invention that functions as a relay station has a filtering function for performing selection control of packets to be relayed. An example of a transfer filter table by the filtering function is shown in FIG. Here, a setting example is shown in which only packets having the source address (MAC address “111xxx” or IP address “1.1.1.1”) of STA 5 are transferred to AP 1 and packets having other source addresses are discarded.

これにより、ＳＴＡ５以外のＳＴＡがネットワーク２へ接続するために、無線通信装置４にアドホックモードでパケットを送信しても、無線通信装置４でそのパケットを破棄することができる。すなわち、第三者が不正にネットワーク２に接続するのを防止でき、安全にネットワーク接続が可能になる。   Thus, even if a STA other than the STA 5 connects to the network 2 and transmits a packet to the wireless communication device 4 in the ad hoc mode, the wireless communication device 4 can discard the packet. That is, it is possible to prevent a third party from illegally connecting to the network 2 and to connect to the network safely.

さらに、認証サーバ３ではなく、認証済みの無線通信装置４がどのＳＴＡのパケットを転送するかを決定するため、認証サーバ３での設定に比べて設定が容易である。すなわち、認証済みの無線通信装置４は、身近にありかつ許可したいＳＴＡに対してネットワーク２を開放する権限をもつため、設定が容易である。したがって、認証サーバ３に登録していないＳＴＡ、あるいはアドホックモードのみに対応しているＳＴＡであっても、一時的かつ容易にネットワーク２に接続することができる。   Furthermore, since the authenticated wireless communication device 4, not the authentication server 3, determines which STA packet to transfer, the setting is easier than the setting in the authentication server 3. In other words, the authenticated wireless communication device 4 is easy to set up because it has the authority to open the network 2 to STAs that are familiar and want to permit. Therefore, even an STA that is not registered in the authentication server 3 or an STA that supports only the ad hoc mode can be connected to the network 2 temporarily and easily.
