本発明の実施形態は、移動体通信システムを構成する無線コアネットワーク(以下、無線コアNWとも称する)を、複数の無線局免許人(以下、免許人とも称する)の間で共有することで、従来よりも柔軟なサービスを実現可能にする。無線コアNWとは、移動体通信システムにおける無線基地局とコアネットワークを指す。また、移動体通信システムは、LTEネットワークを構成するシステムとすることができる。免許人とは、移動体通信事業者を指す。移動体通信事業者とは、例えば、従来からのMNO(Mobile Network Operator)であっても良く、ローカル5G等の自営網を運用する事業者であっても良い。例えば、移動体通信事業者は、警察署や消防署などとすることができる。
続いて、図1~図9を参照して、本発明の第1の実施形態を説明する。
図1は、本実施形態に係る移動体通信システムの構成例を示す。
次に、複数の免許人による無線コアNWの共有について説明する。
本実施形態では、オペレータが、管理システム100において認証制御及び通信制御のための設定を行うことにより、移動体通信システムにおける無線コアNWの共有を実現し、従来よりも柔軟なサービスの提供を可能にする。
まず、本実施形態に係る認証制御について説明する。ここで述べる認証制御とは、異なる免許人(すなわち、移動体通信事業者)が管理する端末装置の識別情報をHSS312に登録することで、MME311による認証処理によって当該識別情報に対応する端末装置の接続が許可されるようにする制御である。
次いで、本実施形態に係る通信制御について説明する。ここで述べる通信制御とは、異なる免許人が管理する端末装置の識別情報をネットワークプラットフォーム200または上位階層のアプリケーションプラットフォームに登録することで、ネットワークプラットフォーム200または上位階層のアプリケーションプラットフォームによって、当該識別情報に対応する端末装置の通信が許可されるようにする制御である。また、管理システム100を介したオペレータによる指示に応じて、端末装置間の通信が制御され得る。さらに、通信の優先度情報を登録することで、優先度に応じた通信の制御を可能にすることができる。このように、ネットワークプラットフォーム200または上位階層のアプリケーションプラットフォームは、通信制御部として機能することができる。
次いで、本実施形態に係るネットワーク切替機能について説明する。本実施形態に係るネットワークプラットフォーム200は、負荷情報収集部210によって収集された負荷情報に基づいて所定の閾値より高い負荷が検知された場合に、ネットワーク切替部230によって一部の端末装置間の通信を他の移動体通信ネットワークに切り替えることができる。切替先である他の移動体通信ネットワークは、LTEネットワークでも良いし、3Gネットワークや5Gネットワークとすることができ、例えばMVNO(Mobile Virtual Network Operator)のネットワークとすることができる。
続いて、図10を参照して、本発明の第2の実施形態を説明する。上述した第1の実施形態は、具体的な実施形態であるが、第2の実施形態は、より一般化された実施形態である。
図10を参照して、第2の実施形態に係る管理システム100の構成例を説明する。
第2の実施形態に係る動作例を説明する。
一例として、第2の実施形態の管理システム100は、第1の実施形態の管理システム100である。この場合に、第1の実施形態についての説明は、第2の実施形態にも適用されうる。
なお、本発明は上述した実施形態に限定されるものではない。上述した実施形態は例示にすぎないということ、及び、本発明のスコープ及び精神から逸脱することなく様々な変形が可能であるということは、当業者に理解されるであろう。
上記実施形態の一部又は全部は、以下の付記のようにも記載され得るが、以下には限られない。
