<1.1.ライセンス>
一般に、周波数の利用のためのライセンス(License)は、各国の周波数管理機関等によって付与される。ライセンスの形態の一例を、下記の表1に示す。
SASは、アメリカにおいて3.5GHz帯に導入が予定されている技術である。SASでは、3層構造のスペクトラムアクセス層が規定されている。詳しくは、優先度が高い順に、「Incumbent Access Tier」、「Priority Access Tier」、及び「General Authorized Access Tier」が規定されている。「Incumbent Access Tier」の無線ネットワークは、排他的に利用可能な周波数を利用することができる。「Priority Access Tier」の無線ネットワークは、一時的に排他的に利用可能な周波数を利用することができる。「General Authorized Access Tier」の無線ネットワークは、排他的でない、即ち干渉保護が保証されていない周波数を利用することができる。
しかし、SASの枠組みにおいて、上記アーキテクチャを導入することは困難である。この困難さについて、図2を参照しながら説明する。
そこで、本開示の一実施形態では、周波数の移転又は賃貸を実現することが可能なSASのアーキテクチャを開示する。本アーキテクチャについて、図3を参照して説明する。
802.19 Task Group 1a(TG1a)で検討が進められているTVホワイトスペースを含む6GHz以下の周波数帯における同種又は異種ネットワーク間共存技術(P802.19.1a)に関しても、適用可能である。P802.19.1aのベースとなる標準規格であるIEEE Std 802.19.1TM-2014における、「Proxy/Network Manager」に相当するCM(Coexistence Manager)は、他のCMとの間で周波数の移転又は賃貸を行うことはなく、やり取りのためのインタフェースも有していない。そのため、IEEE P802.19.1aに関しても、本技術の適用が可能である。
以下、図4及び図5を参照しながら、上述した新たなアーキテクチャの適用が想定されるシナリオの一例を説明する。図4及び図5は、上記説明した新たなアーキテクチャの導入が想定されるシナリオを具体的に説明するための説明図である。
まず、図6~図8を参照して、各実施形態において共通するシステム及び各装置の構成例を説明する。
<2.1.システムの構成例>
図6は、本実施形態に係るシステム1の構成の一例を示す図である。図6に示すように、本実施形態に係るシステム1は、ネットワークマネージャ100A、100B、無線通信装置200A-1~200A-2、200B-1~200B-2、及び周波数管理サーバ300を含む。
周波数管理サーバ300は、各無線ネットワークが優先的に利用する周波数に関する情報を管理する装置である。周波数管理サーバ300は、例えばジオロケーションデータベース(Geo-location database)又はSASデータベースのようなエンティティに相当する。なお、周波数管理サーバ300は、周波数管理装置に相当する。
無線通信装置200は、ネットワークマネージャ100による制御に基づいて、配下のユーザ端末に無線サービスを提供する装置である。無線通信装置200は、典型的には、eNB又はアクセスポイント等の基地局である。基地局200と配下のユーザ端末とは、無線システムを形成する。
ネットワークマネージャ100は、複数の無線システムから成る無線ネットワークを制御するエンティティである。ネットワークマネージャ100は、例えばIEEE802.19.1の「Coexistence manager」、ETSI EN 303 387の「Spectrum coordinator」、SASアーキテクチャの「Proxy/Network manager」、セルラーネットワークのOAM(operations, administration, and management)、又は各事業者が独自にもつ中央制御装置に相当し得る。
本明細書においては、優先度とは、チャネルの利用優先度を意味するものとする。例えば、アメリカの3.5GHz帯におけるチャネル優先度を優先度が高い順に記載すると、「Priority access license (PAL) channel」>「Reserved channel」>「general authorized access (GAA) channel」である。他にも、優先度は、例えば表1に示した、周波数帯域利用に係る権限(Authorization)の種類を意味していてもよい。周波数帯域利用に係る権限の種類を優先度が高い順に記載すると、「Traditional licensing」の「Individual authorization」>「Light-licensing」の「Individual authorization」>「Light-licensing」の「General authorization」>「License-exempt」な「General authorization」である。また、優先度は、ネットワークマネージャ100の管理対象の無線ネットワークに含まれる無線システムの種類を意味していてもよい。無線システムの種類を優先度が高い順に記載すると、「Public safety (Mission critical)」>「Public safety」>「General use (Mission critical)」>「General use」である。また、優先度は、ネットワークマネージャ100における上記無線システムに寄与(Serve)する割合を意味していてもよい。また、優先度は、代理手続きを行うインセンティブの大きさを意味していてもよい。また、優先度は、割り当てられたQoSの優先度の高さを意味していてもよい。
図7は、本実施形態に係るネットワークマネージャ100の構成の一例を示すブロック図である。図7に示すように、ネットワークマネージャ100は、ネットワーク通信部110、記憶部120及び処理部130を含む。
ネットワーク通信部110は、情報を送受信する。例えば、ネットワーク通信部110は、他のノードへの情報を送信し、他のノードからの情報を受信する。例えば、上記他のノードは、他のネットワークマネージャ100、配下の基地局200、及び周波数管理サーバ300を含む。
記憶部120は、ネットワークマネージャ100の動作のためのプログラム及び様々なデータを一時的に又は恒久的に記憶する。
処理部130は、ネットワークマネージャ100の様々な機能を提供する。処理部130は、管理部131、交渉部132、情報交換部133、報告部134及び発見部135を含む。なお、処理部130は、これらの構成要素以外の他の構成要素をさらに含み得る。即ち、処理部130は、これらの構成要素の動作以外の動作も行い得る。
図8は、本実施形態に係る基地局200の構成の一例を示すブロック図である。図8を参照すると、基地局200は、アンテナ部210、無線通信部220、ネットワーク通信部230、記憶部240及び処理部250を備える。
アンテナ部210は、無線通信部220により出力される信号を電波として空間に放射する。また、アンテナ部210は、空間の電波を信号に変換し、当該信号を無線通信部220へ出力する。
無線通信部220は、信号を送受信する。例えば、無線通信部220は、ユーザ端末へのダウンリンク信号を送信し、ユーザ端末からのアップリンク信号を受信する。
ネットワーク通信部230は、情報を送受信する。例えば、ネットワーク通信部230は、他のノードへの情報を送信し、他のノードからの情報を受信する。例えば、上記他のノードは、他の基地局200、コアネットワークノード及び基地局200自身を管理するネットワークマネージャ100を含む。
記憶部240は、基地局200の動作のためのプログラム及び様々なデータを一時的に又は恒久的に記憶する。
処理部250は、基地局200の様々な機能を提供する。処理部250は、通信制御部251及び交渉部253を含む。なお、処理部250は、これらの構成要素以外の他の構成要素をさらに含み得る。即ち、処理部250は、これらの構成要素の動作以外の動作も行い得る。
以下、各実施形態について詳細に説明する。
本実施形態は、ネットワークマネージャ100Aが、周波数管理サーバ300との間で発生する共用周波数帯域の利用に係る手続きを、ネットワークマネージャ100Bの代理で行う形態である。
ネットワークマネージャ100(例えば、管理部131)は、ひとつ以上の基地局200を管理する。例えば、ネットワークマネージャ100は、配下のひとつ以上の無線システム(即ち、基地局200及びユーザ端末)に利用させる周波数帯を制御する。ネットワークマネージャ100Aの管理対象の基地局200Aを含む無線システムを、以下では第1の無線システムとも称する。また、ネットワークマネージャ100Bの管理対象の基地局200Bを含む無線システムを、以下では第2の無線システムとも称する。
以下、図9及び図10を参照して、ネットワークマネージャ100Bが周波数共用に関する情報を取得するための処理の流れを説明する。
本実施形態によれば、周波数管理サーバ300への接続性を持たないネットワークマネージャ100Bは、ネットワークマネージャ100Aが代理で取得した周波数共用に関する情報を取得することが可能となる。また、周波数管理サーバ300への接続性を持たないネットワークマネージャ100Bは、ネットワークマネージャ100Aが代理で取得した高優先度アクセス権を取得し、配下の基地局200Bに行使させることが可能となる。また、ネットワークマネージャ100A及びネットワークマネージャ100Bは、配下の無線システムに関する情報を交換することで、互いの配下の無線システムの共存制御を実施することが可能となる。
本実施形態は、異なる無線ネットワーク間で、高優先度アクセス権の移転又は賃貸を行う形態である。なお、移転とは売却を含む概念であるものとする。
ネットワークマネージャ100A(例えば、交渉部132)は、周波数管理サーバ300から高優先度アクセス権を取得する。ネットワークマネージャ100Aにより取得された高優先度アクセス権が行使された周波数帯域は、典型的には基地局200Aにより利用され得る。しかし、とりわけ本実施形態では、ネットワークマネージャ100Aにより取得された高優先度アクセス権が行使された周波数帯域は、基地局200Bにより利用され得る。そのために、ネットワークマネージャ100A(例えば、交渉部132)は、取得した高優先度アクセス権を、ネットワークマネージャ100Bからのリクエストに応じてネットワークマネージャ100Bへ移転又は賃貸する。なお、高優先度アクセス権は、行使前に移転又は賃貸されてもよいし、行使後に(即ち、高優先度アクセスが可能な周波数帯域が確定後に)移転又は賃貸されてもよい。
以下、図11を参照して、高優先度アクセス権の移転又は賃貸に係る処理の流れを説明する。
本実施形態によれば、ネットワークマネージャ100Aは、配下の無線ネットワークにおいては必要性が低い高優先度アクセス権を、ネットワークマネージャ100Bへ移転又は賃貸することが可能となる。これにより、例えば複数の事業者間で、高優先度アクセス権が有効に活用されることとなる。
本実施形態は、異なる無線ネットワーク間で、高優先度アクセスを実施中の周波数帯域の二次利用を行う形態である。
第1の例として、ネットワークマネージャ100Aは、ネットワークマネージャ100Bからのリクエストに基づいて、基地局200Bに周波数の二次利用を許可してもよい。その場合の、ネットワークマネージャ100Aとネットワークマネージャ100Bとの間で交換される、周波数共用に関する情報について説明する。
以下、図12及び図13を参照して、高優先度アクセスを実施中の周波数帯域を二次利用に係る処理の流れを説明する。なお、図12は第1の例に係る処理の流れを示し、図12は第2の例に係る処理の流れを示す。
例えば、特定の地理領域において、基地局200Aだけではネットワークカバレッジを確保できないものの、基地局200Bを含めればネットワークカバレッジを確保可能な場合が想定される。そのような場合、第2の例に関し説明したように、ネットワークマネージャ100Aは、ネットワークマネージャ100Bへ第2の周波数二次利用リクエストを送信することで、ネットワークカバレッジを確保することが可能となる。よって、ネットワークマネージャ100Aは、配下のユーザ端末に対して、同一周波数帯域でのネットワークカバレッジを提供することが可能となる。よって、ユーザ端末は、異なる周波数帯域でのメジャメント(Inter-frequency measurement)という負荷のかかる処理を回避可能となる。なお、ユーザ端末は、基地局200Aから基地局200Bへのハンドオーバに際して、ローミングとならないよう処理を行ってもよい。また、屋内/屋外に基づく判定を経ることで、屋外での二次利用による干渉が防止される。このような適用例は、図4及び図5を参照して上記説明したシナリオの通りである。
本実施形態は、異なるネットワークマネージャ100に属する無線システム間で、周波数共用を含むキャリアアグリゲーションを行う形態である。
本実施形態に係る基地局200(例えば、通信制御部251)は、自身が提供する周波数帯域と、他のネットワークマネージャ100により管理される基地局200による周波数共用により提供される周波数帯域とを用いて、キャリアアグリゲーションを行う。なお、いずれの周波数帯域がプライマリセルとして用いられてもよい。
以下、図14を参照して、周波数共用を含むキャリアアグリゲーションに係る処理の流れを説明する。
本実施形態によれば、異なる事業者間でのキャリアアグリゲーションが可能となる。また、同一事業者内でも、異なるネットワークマネージャ100の配下の基地局200間でのキャリアアグリゲーションが可能となる。このことは、管理領域ごとに利用可能なチャネルが異なる場合に有効である。
本開示に係る技術は、様々な製品へ応用可能である。例えば、ネットワークマネージャ100は、タワーサーバ、ラックサーバ、又はブレードサーバなどのいずれかの種類のサーバとして実現されてもよい。また、ネットワークマネージャ100の少なくとも一部の構成要素は、サーバに搭載されるモジュール(例えば、1つのダイで構成される集積回路モジュール、又はブレードサーバのスロットに挿入されるカード若しくはブレード)において実現されてもよい。
図15は、本開示に係る技術が適用され得るサーバ700の概略的な構成の一例を示すブロック図である。サーバ700は、プロセッサ701、メモリ702、ストレージ703、ネットワークインタフェース704及びバス706を備える。
(第1の応用例)
図16は、本開示に係る技術が適用され得るeNBの概略的な構成の第1の例を示すブロック図である。eNB800は、1つ以上のアンテナ810、及び基地局装置820を有する。各アンテナ810及び基地局装置820は、RFケーブルを介して互いに接続され得る。
図17は、本開示に係る技術が適用され得るeNBの概略的な構成の第2の例を示すブロック図である。eNB830は、1つ以上のアンテナ840、基地局装置850、及びRRH860を有する。各アンテナ840及びRRH860は、RFケーブルを介して互いに接続され得る。また、基地局装置850及びRRH860は、光ファイバケーブルなどの高速回線で互いに接続され得る。
以上、図1~図17を参照して、本開示の一実施形態について詳細に説明した。上記説明したように、本実施形態に係るネットワークマネージャ100Aは、ひとつ以上の基地局200Aを管理しつつ、ひとつ以上の基地局200Bを管理するネットワークマネージャ100Bとの間で、基地局200Bによる周波数共用に関する情報を交換し、この周波数共用に関する情報は、高優先度アクセスが可能な周波数帯域に関する情報を含む。かかる構成により、ネットワークマネージャ100Aとネットワークマネージャ100Bとは、各々が管理する基地局200に割り当てられた高優先度の周波数を共用するための情報交換を行うことが可能となり、周波数リソースのより効率的な活用が実現される。
