　以下、図面とともにゲートウェイ選択方法及び通信システムの実施形態について詳細に説明する。なお、図面の説明においては同一要素には同一符号を付し、重複する説明を省略する。また、以下の説明における実施形態は、本発明の具体例であり、特に本発明を限定する旨の記載がない限り、これらの実施形態に限定されないものとする。 Hereinafter, embodiments of a gateway selection method and a communication system will be described in detail with reference to the drawings. In the description of the drawings, the same elements will be denoted by the same reference symbols, without redundant description. Further, the embodiments in the following description are specific examples of the present invention, and unless otherwise stated, the present invention is not limited to these embodiments.
　図１は、本発明の一実施形態に係る通信システム９のシステム構成図である。この通信システム９は、ＵＥ１、ｅＰＤＧ（evolved　Packet　Data　Gateway）２、ＡＡＡサーバ３、ＨＳＳ（Home　Subscriber　Server）４、ＭＭＥ（Mobility　Management　Entity）５、ＰＧＷ６、ＳＧＷ（Serving　Gateway）７及びｅＮＢ（evolved　NodeB）８を含んで構成されている。 FIG. 1 is a system configuration diagram of a communication system 9 according to an embodiment of the present invention. This communication system 9 includes UE1, ePDG (evolved packet data gateway) 2, AAA server 3, HSS (home subscriber server) 4, MME (Mobility Management Entity) 5, PGW 6, SGW (Serving Gateway) 7 and eNB (evolved NodeB). 8) is included.
　通信システム９は、図１に示す通り、セルラ通信（３ＧＰＰアクセス、3GPP　access）及び非セルラ通信（非３ＧＰＰアクセス、non-3GPP　access）により通信サービスを提供するシステムである。ここで、セルラ通信とは、地域をセル状に分割して基地局を設置し、周波数を有効に利用する無線方式による通信であり、具体的には、３Ｇ（3rd　Generation）通信、４Ｇ（4th　Generation）通信及びＬＴＥ（Long　Term　Evolution）通信等が挙げられる。一方、非セルラ通信とは、セルラ通信以外の通信であり、具体的には、無線ＬＡＮ（Local　Area　Network）通信及びBluetooth（登録商標）通信等が挙げられる。また、通信サービスとは、通信を用いたサービスであり、動画配信や車車間通信等のサービスである。それぞれの通信サービスにおいて、要求されるネットワーク要件等が異なる。上述のセルラ通信や非セルラ通信、さらにはそれら通信を実現するための各ノードの詳細等については、上述の非特許文献１を参照されたい。非特許文献１で説明されている内容については、本実施形態では適宜省略する。 The communication system 9 is a system for providing communication services by cellular communication (3GPP access, 3GPP access) and non-cellular communication (non-3GPP access, non-3GPP access) as shown in FIG. Here, the cellular communication is a communication by a wireless method in which a region is divided into cells, a base station is installed, and a frequency is effectively used. Specifically, 3G (3rd Generation) communication, 4G (4th (4th) Communication, LTE (Long Term Evolution) communication, and the like. On the other hand, non-cellular communication is communication other than cellular communication, and specific examples include wireless local area network (LAN) communication and Bluetooth (registered trademark) communication. The communication service is a service using communication, and is a service such as video distribution and inter-vehicle communication. In each communication service, required network requirements etc. are different. For details of the above-mentioned cellular communication and non-cellular communication, and details of each node for realizing the communication, etc., refer to the above-mentioned Non-Patent Document 1. The contents described in Non-Patent Document 1 will be appropriately omitted in this embodiment.
　また、通信システム９が提供するセルラ通信は、特定用途向けの専用のコアネットワーク（Dedicated　Core　Network。以降「ＤＥＣＯＲ」と呼ぶ）に基づくアーキテクチャ（以降「ＤＥＣＯＲ方式」と呼ぶ）により実現されている。ＤＥＣＯＲ方式の詳細については、下記の非特許文献２を参照されたい。非特許文献２で説明されている内容については、本実施形態では適宜省略する。
　非特許文献２：3GPP　TS　23.401　V13.7.0　(2016-06) Further, cellular communication provided by the communication system 9 is realized by an architecture (hereinafter referred to as “DECOR system”) based on a dedicated core network (Dedicated Core Network, hereinafter referred to as “DECOR”) for specific application. For details of the DECOR method, refer to Non-Patent Document 2 below. The contents described in Non-Patent Document 2 will be appropriately omitted in the present embodiment.
Non-Patent Document 2: 3GPP TS 23.401 V 13.7.0 (2016-06)
　ＤＥＣＯＲ方式では、セルラ通信を行うＵＥがセルラ通信を行う場合に、まずはデフォルトＭＭＥにアクセスし、ＵＥの種別や用途を示す端末情報（端末識別子）である「UE　Usage　type」に応じたＤＥＣＯＲにＵＥが振り分けられる。ここで、従来のＤＥＣＯＲ方式は、セルラ通信を行うＵＥを対象としたものであり、非セルラ通信を行うＵＥはＤＥＣＯＲ方式を活用することができない。本実施形態の通信システム９は、後述の機能構成により、非セルラ通信を行うＵＥにおいてもＤＥＣＯＲ方式に基づくＵＥの振り分けを行うことができるようにするものである。 In the DECOR method, when a UE performing cellular communication performs cellular communication, first, a default MME is accessed, and a UE corresponding to "UE Usage type", which is terminal information (terminal identifier) indicating the type and use of the UE, Is distributed. Here, the conventional DECOR scheme is intended for UEs that perform cellular communication, and UEs that perform non-cellular communication can not utilize the DECOR scheme. The communication system 9 according to the present embodiment is configured to be able to distribute UEs based on the DECOR method even in UEs that perform non-cellular communication by the functional configuration described later.
　また、通信システム９では、図１に示す通り、複数のスライス（スライス１、スライス２及びスライス３）が構築されている。スライスとは、ネットワーク装置のリンクとノードの資源を仮想的に切り分けて、切り分けた資源を結合し、ネットワークインフラ上に論理的に生成される仮想ネットワーク又はサービス網であり、スライス同士は資源を分離しており、互いに干渉しない。スライス１は、ＭＭＥ５Ｂにより収容され、ｅＰＤＧ２Ａ、ＰＧＷ６Ａ及びＳＧＷ７Ａのリソースを確保している。スライス２は、ＭＭＥ５Ｃにより収容され、ｅＰＤＧ２Ｂ、ＰＧＷ６Ｂ及びＳＧＷ７Ｂのリソースを確保しており、スライス３は、後述の「信頼されている非３ＧＰＰアクセス」からのみアクセス可能であり、ＰＧＷ６Ｃのリソースを確保している。 Further, in the communication system 9, as shown in FIG. 1, a plurality of slices (slice 1, slice 2 and slice 3) are constructed. A slice is a virtual network or service network logically created on the network infrastructure by virtually separating the link of the network device and the resources of the node and combining the separated resources, and the slices separate resources. And do not interfere with each other. The slice 1 is accommodated by the MME 5B, and secures resources of the ePDG 2A, PGW 6A, and SGW 7A. Slice 2 is accommodated by MME 5 C and secures the resources of ePDG 2 B, PGW 6 B and SGW 7 B, and slice 3 is accessible only from “trusted non-3GPP access” described later, and secures PGW 6 C resources. ing.
　続いて、通信システム９を構成する各ノードについて説明する。 Then, each node which comprises the communication system 9 is demonstrated.
　ＵＥ１（通信端末）は、非セルラ通信を行うスマートフォンや電子機器等のコンピュータ端末であり、通信システム９と無線等により通信を行うことができる。ＵＥ１は、非セルラ通信により複数の通信サービスを利用可能である。なお、ＵＥ１は、さらにセルラ通信により複数の通信サービスを利用可能であってもよい。ＵＥ１は、ＮＡＩ（Network　Access　Identity、端末ＩＤ）等、自端末の識別情報を格納しており、当該識別情報をｅＰＤＧ２又はＡＡＡサーバ３へ送信する。ＵＥ１は、非セルラ通信のうち「信頼されていない非３ＧＰＰアクセス」を利用する場合、ｅＰＤＧ２を経由してＡＡＡサーバ３へ通信する。また、ＵＥ１は、非セルラ通信のうち「信頼されている非３ＧＰＰアクセス」を利用する場合、ｅＰＤＧ２を経由することなくＡＡＡサーバ３へ通信する。 The UE 1 (communication terminal) is a computer terminal such as a smartphone or an electronic device that performs non-cellular communication, and can communicate with the communication system 9 by radio or the like. The UE 1 can use a plurality of communication services by non-cellular communication. The UE 1 may further be able to use a plurality of communication services by cellular communication. The UE 1 stores identification information of the own terminal such as NAI (Network Access Identity, terminal ID), and transmits the identification information to the ePDG 2 or the AAA server 3. The UE 1 communicates with the AAA server 3 via the ePDG 2 when using “non-trusted non-3GPP access” of non-cellular communication. Moreover, UE1 communicates with the AAA server 3 without passing through the ePDG 2 when using “trusted non-3GPP access” in non-cellular communication.
　ｅＰＤＧ２（ゲートウェイ装置）は、コアネットワークと無線ＬＡＮ等とのゲートウェイ装置としてユーザデータの送信を行う部分であり、ＵＥ１と通信するゲートウェイ装置である。図１に示す通信システム９では、スライス１に「ｅＰＤＧ１」が含まれ、スライス２に「ｅＰＤＧ２」が含まれている。本実施形態では、「ｅＰＤＧ１」や「ｅＰＤＧ２」等の複数を総称してｅＰＤＧ２と適宜呼ぶ。 The ePDG 2 (gateway device) is a part that transmits user data as a gateway device of a core network, a wireless LAN or the like, and is a gateway device that communicates with the UE 1. In the communication system 9 illustrated in FIG. 1, slice 1 includes “ePDG 1” and slice 2 includes “ePDG 2”. In the present embodiment, a plurality of "ePDG1", "ePDG2" and the like are collectively referred to as ePDG2 as appropriate.
　ＡＡＡサーバ３は、無線ＬＡＮ等を経由してアクセスするＵＥ１のアクセス制御を行うサーバ装置である。 The AAA server 3 is a server device that performs access control of the UE 1 accessed via a wireless LAN or the like.
　ＨＳＳ４（ユーザ情報データベース）は、ＵＥ１等の通信端末の契約情報、認証情報、通信サービス情報、端末タイプ情報及び在圏情報を含むユーザ情報（加入者情報）をデータベースで管理するサーバである。 The HSS 4 (user information database) is a server that manages user information (subscriber information) including contract information, authentication information, communication service information, terminal type information, and location information of communication terminals such as UE 1 in a database.
　ＭＭＥ５（移動制御装置）は、セルラ通信等の移動体通信における移動制御を行うサーバ装置である。図１に示す通信システム９では、セルラ通信（移動体通信）における移動制御を行う複数のＭＭＥ５が含まれている。複数のＭＭＥ５のうち、セルラ通信を行うＵＥ（移動体端末）がセルラ通信を行う場合に最初にアクセスするＭＭＥ５が「デフォルトＭＭＥ」（＝ＭＭＥ５Ａ、デフォルト移動制御装置）であり、その後にＵＥが振り分けられるＤＥＣＯＲを収容するＭＭＥ５が「専用ＭＭＥ１」（＝ＭＭＥ５Ｂ）及び「専用ＭＭＥ２」（＝ＭＭＥ５Ｃ）である。本実施形態では、「デフォルトＭＭＥ」、「専用ＭＭＥ１」、「専用ＭＭＥ２」等の複数を総称してＭＭＥ５と適宜呼ぶ。 The MME 5 (movement control apparatus) is a server apparatus that performs movement control in mobile communication such as cellular communication. The communication system 9 illustrated in FIG. 1 includes a plurality of MMEs 5 that perform movement control in cellular communication (mobile communication). Among the plurality of MMEs 5, the MME 5 to be accessed first when the UE (mobile terminal) performing the cellular communication performs the cellular communication is the "default MME" (= MME 5A, default mobility control device), and the UE distributes thereafter MME5 which accommodates the DECOR to be stored is "dedicated MME1" (= MME5B) and "dedicated MME2" (= MME5C). In the present embodiment, a plurality of “default MME”, “dedicated MME 1”, “dedicated MME 2” and the like are collectively referred to as “MME 5” as appropriate.
　ＰＧＷ６（ゲートウェイ装置）は、ＰＤＮ（Packet　data　network、アクセス先）とコアネットワークとのゲートウェイであり、ユーザデータ（パケットデータ）を送信する。すなわち、ＰＧＷ６は、パケット転送するゲートウェイ装置である。 The PGW 6 (gateway device) is a gateway between a packet data network (PDN) and a core network, and transmits user data (packet data). That is, the PGW 6 is a gateway device that transfers packets.
　ＳＧＷ７は、ｅＮＢ８等のセルラ通信網の基点となり、ＰＧＷ６との間でユーザデータの中継処理を行うゲートウェイ装置である。 The SGW 7 is a gateway device that performs relay processing of user data with the PGW 6 as a base point of a cellular communication network such as the eNB 8.
　ｅＮＢ８は、いわゆる基地局である。 The eNB 8 is a so-called base station.
　続いて、ＡＡＡサーバ３の機能の詳細について説明する。図２は、ＡＡＡサーバ３の機能ブロック図である。図２に示す通り、ＡＡＡサーバ３は、特定部３０及び選択部３１を含んで構成される。 Subsequently, details of the function of the AAA server 3 will be described. FIG. 2 is a functional block diagram of the AAA server 3. As shown in FIG. 2, the AAA server 3 is configured to include a specifying unit 30 and a selecting unit 31.
　特定部３０は、ＵＥ１の種別又は用途を示す「UE　Usage　type」（端末情報）を特定する。具体的には、特定部３０は、ＵＥ１又はｅＰＤＧ２からアクセス依頼と共にＵＥ１のＮＡＩを受信する。次に、特定部３０は、ＨＳＳ４に対してユーザ情報照合を行い、ＵＥ１のＮＡＩをＨＳＳ４に送信する。次に、特定部３０は、ユーザ情報照合の応答として照合結果であるＵＥ１の「UE　Usage　type」を受信することで、ＵＥ１の「UE　Usage　type」を特定する。特定部３０は、特定した「UE　Usage　type」を選択部３１に出力する。 The identifying unit 30 identifies “UE Usage type” (terminal information) indicating the type or use of the UE 1. Specifically, the specifying unit 30 receives the NAI of UE1 together with the access request from UE1 or ePDG2. Next, the identifying unit 30 collates the user information with the HSS 4 and transmits the NAI of the UE 1 to the HSS 4. Next, the identification unit 30 identifies the “UE Usage type” of the UE 1 by receiving the “UE Usage type” of the UE 1 that is the collation result as a response to the user information collation. The identifying unit 30 outputs the identified “UE Usage type” to the selecting unit 31.
　選択部３１は、特定部３０により特定された「UE　Usage　type」に対応するＰＧＷ６又はｅＰＤＧ２とＰＧＷ６との組み合わせを選択する。具体的には、選択部３１は、ＭＭＥ５Ａに対してアクセス先確認を行い、特定部３０から入力された「UE　Usage　type」をＭＭＥ５Ａに送信する。次に、選択部３１は、アクセス先確認の応答として確認結果であるＰＧＷ６のＩＤ（識別情報）を受信する。次に、選択部３１は、ＤＮＳ（Domain　Name　System）（不図示）に対して名前解決を行い、受信したＰＧＷ６のＩＤをＤＮＳに送信する。なお、ＤＮＳは、一般的なＤＮＳの機能（名前解決機能等）を備えているものとする。次に、選択部３１は、名前解決の応答として解決結果であるＰＧＷ６のアドレス（ネットワークアドレス）、又はｅＰＤＧ２のアドレスとＰＧＷ６のアドレスとの組み合わせを受信することで、ＰＧＷ６又はｅＰＤＧ２とＰＧＷ６との組み合わせ（ＵＥ１と通信するゲートウェイ装置とパケット転送するゲートウェイ装置との組み合わせ）を選択する。選択部３１は、受信したＰＧＷ６のアドレス又はｅＰＤＧ２のアドレスとＰＧＷ６のアドレスとの組み合わせをｅＰＤＧ２やＵＥ１等の他のノードや装置に出力する。 The selection unit 31 selects a combination of PGW 6 or ePDG 2 and PGW 6 corresponding to the “UE Usage type” specified by the specification unit 30. Specifically, the selection unit 31 performs access destination confirmation on the MME 5A, and transmits “UE Usage type” input from the identification unit 30 to the MME 5A. Next, the selection unit 31 receives the ID (identification information) of the PGW 6 that is the confirmation result as a response to the access destination confirmation. Next, the selection unit 31 performs name resolution on a DNS (Domain Name System) (not shown), and transmits the received ID of the PGW 6 to the DNS. The DNS is assumed to have a general DNS function (name resolution function etc.). Next, the selection unit 31 receives the address (network address) of PGW 6 or the combination of the address of ePDG 2 and the address of PGW 6 which is a solution result as a response of name resolution, thereby combining PGW 6 or ePDG 2 and PGW 6 (A combination of a gateway apparatus communicating with UE 1 and a gateway apparatus transferring packets) is selected. The selection unit 31 outputs the received address of the PGW 6 or the combination of the address of the ePDG 2 and the address of the PGW 6 to another node or device such as the ePDG 2 or the UE 1.
　続いて、ＨＳＳ４の機能の詳細について説明する。図３は、ＨＳＳ４の機能ブロック図である。図３に示す通り、ＨＳＳ４は、端末情報格納部４０を含んで構成される。 Subsequently, the details of the functions of the HSS 4 will be described. FIG. 3 is a functional block diagram of the HSS 4. As shown in FIG. 3, the HSS 4 includes a terminal information storage unit 40.
　端末情報格納部４０は、一般的なＨＳＳが格納する、ＵＥ１のユーザに関するユーザ情報を格納する。端末情報格納部４０は、ＵＥ１の「UE　Usage　type」をさらに格納する。具体的には、端末情報格納部４０は、ＮＡＩと「UE　Usage　type」とを対応付けたＮＡＩ情報をさらに格納する。図４は、端末情報格納部４０に格納されたＮＡＩ情報のテーブル例を示す図である。図４に示すＮＡＩ情報のテーブル例において、例えば、ＮＡＩである文字列「ＡＡＡ」と、「UE　Usage　type」である文字列「ＸＸＸ」とが対応付けて格納されている。端末情報格納部４０は、特定部３０からユーザ情報照合が行われると、格納されているＮＡＩ情報を参照し、ユーザ情報照合と共に受信したＵＥ１のＮＡＩに対応付けられた「UE　Usage　type」を抽出し、照合結果として抽出した「UE　Usage　type」を特定部３０に送信する。すなわち、特定部３０は、端末情報格納部４０（ＨＳＳ４）に格納されたＮＡＩ情報を参照して端末情報を特定する。 The terminal information storage unit 40 stores user information on the user of the UE 1 stored by a general HSS. The terminal information storage unit 40 further stores the “UE Usage type” of the UE 1. Specifically, the terminal information storage unit 40 further stores NAI information in which the NAI is associated with "UE Usage type". FIG. 4 is a diagram showing an example of a table of NAI information stored in the terminal information storage unit 40. As shown in FIG. In the example of the table of NAI information shown in FIG. 4, for example, the character string “AAA” that is the NAI and the character string “XXX” that is the “UE Usage type” are stored in association with each other. The terminal information storage unit 40 refers to the stored NAI information and extracts the “UE Usage type” associated with the NAI of the UE 1 received along with the user information collation, when the user information collation is performed from the specifying unit 30. And transmits the “UE Usage type” extracted as the matching result to the identifying unit 30. That is, the identifying unit 30 identifies terminal information with reference to the NAI information stored in the terminal information storage unit 40 (HSS 4).
　続いて、ＭＭＥ５Ａの機能の詳細について説明する。図５は、ＭＭＥ５Ａの機能ブロック図である。図５に示す通り、ＭＭＥ５Ａは、アクセス先情報格納部５０を含んで構成される。 Then, the detail of the function of MME5A is demonstrated. FIG. 5 is a functional block diagram of the MME 5A. As shown in FIG. 5, the MME 5A is configured to include an access destination information storage unit 50.
　アクセス先情報格納部５０は、「UE　Usage　type」と、当該「UE　Usage　type」に応じたセルラ通信を行うＭＭＥ５のグループＩＤであるＭＭＥ－ＧＩ（MME　Group　ID）と、当該「UE　Usage　type」に応じた非セルラ通信を行うＰＧＷ６のＩＤとを対応付けたアクセス先情報（対応情報）を格納する。図６は、アクセス先情報格納部５０に格納されたアクセス先情報のテーブル例を示す図である。図６に示すアクセス先情報のテーブル例において、例えば、「UE　Usage　type」である文字列「ＸＸＸ」と、ＭＭＥ－ＧＩである文字列「１」と、ＰＧＷ６のＩＤである文字列「ＰＧＷ１」とが対応付けて格納されている。なお、ＭＭＥ－ＧＩについては、ＵＥがセルラ通信を行う場合に利用するものであり、本実施形態では説明を省略するが、本テーブル例のように、セルラ通信用の情報（ＭＭＥ－ＧＩ）と非セルラ通信用の情報（ＰＧＷ６のＩＤ）とを組み合わせて格納することで、セルラ通信用のＵＥと非セルラ通信用のＵＥとを区別することなく１つのシステムで通信システム９を実現することができる。アクセス先情報格納部５０は、選択部３１からアクセス先確認が行われると、格納されているアクセス先情報を参照し、アクセス先確認と共に受信したＵＥ１の「UE　Usage　type」に対応付けられたＰＧＷ６のＩＤを抽出し、確認結果として抽出したＰＧＷ６のＩＤを選択部３１に送信する。すなわち、選択部３１は、アクセス先情報格納部５０（ＭＭＥ５Ａ）に格納されたアクセス先情報を参照してＰＧＷ６又はｅＰＤＧ２とＰＧＷ６との組み合わせを選択する。 The access destination information storage unit 50 includes “UE Usage type”, MME-GI (MME Group ID) which is a group ID of MME 5 that performs cellular communication according to the “UE Usage type”, and the “UE Usage type”. Access destination information (correspondence information) associated with the ID of the PGW 6 that performs non-cellular communication according to the above. FIG. 6 is a diagram showing an example of a table of access destination information stored in the access destination information storage unit 50. As shown in FIG. In the example table of the access destination information shown in FIG. 6, for example, a character string "XXX" which is "UE Usage type", a character string "1" which is MME-GI, and a character string "PGW1" which is an ID of PGW6. And are stored in association with each other. Note that MME-GI is used when the UE performs cellular communication, and although the description is omitted in this embodiment, information (MME-GI) for cellular communication is used as in the example of this table. By combining and storing information for non-cellular communication (ID of PGW 6), the communication system 9 can be realized in one system without differentiating between UE for cellular communication and UE for non-cellular communication. it can. When the access destination confirmation is performed from the selection unit 31, the access destination information storage unit 50 refers to the stored access destination information, and the PGW 6 associated with the “UE Usage type” of the UE 1 received along with the access destination confirmation. The ID of PGW 6 extracted as the confirmation result is transmitted to the selection unit 31. That is, the selection unit 31 refers to the access destination information stored in the access destination information storage unit 50 (MME 5A), and selects a combination of PGW 6 or ePDG 2 and PGW 6.
