Abstract
Description
以下、図面を参照して本発明の実施の形態について説明する。図1を用いて本発明の実施の形態1にかかる移動通信システムの構成例について説明する。本図の移動通信システムは、移動通信装置11、ネットワークオペレータ装置12及びサービスプラットフォーム13を有している。
続いて、図2を用いて本発明の実施の形態2にかかる移動通信システムの構成例について説明する。以下、主にM2M(Machine to Machine)通信について説明を行うが、本発明は、M2M通信の適用に限定されるものではなく、一般的な通信等にも適用することができる。本図の移動通信システムは、M2M(Machine to Machine)デバイス21、NWノード23、中継装置26、M2Mサービス(プラットフォーム)PF27及びアプリケーションサーバ29を有している。ここで、M2Mデバイス21は、移動通信装置11に相当する。NWノード23及び中継装置26は、ネットワークオペレータ装置12に相当する。M2MサービスPF27は、サービスプラットフォーム13に相当する。NWノード23及び中継装置26は、ネットワークを構成する。NWノード23及び中継装置26が構成するネットワークは、移動通信網、固定通信網、PLCに用いられるネットワーク等であってもよい。移動通信網には、3GPPにおいて規定される2G/3G/LTE等のネットワークであってもよく、PHSネットワーク、Wimaxネットワークもしくは無線LAN等であってもよい。
続いて、図12のように、M2Mデバイス21がセンサから取得した情報を定期的にアプリケーションサーバ29へ送信する場合のNWパラメータの変更処理の流れについて説明する。
続いて、図13を用いて本発明の実施の形態4にかかるNWパラメータの設定処理の流れについて説明する。はじめに、M2Mデバイス21は、アプリケーションサーバ29へイベント通知メッセージを送信する(S21)。ステップS22及びS23は、図10のステップS13及びS14と同様であるため詳細な説明を省略する。
続いて、M2MサービスPF27から、中継装置26へ通知するNWアシスト情報の他の例について説明する。M2MサービスPF27は、例えばM2Mデバイス21におけるデータ通信量の変化、通信間隔の変化等に関する情報を定期的に収集する。この場合、M2MサービスPF27は、例えば所定期間におけるデータ通信量の平均値、最大値、もしくは、最小値等を算出してもよい。また、M2MサービスPF27は、データ通信量の分散を算出し、算出した分散に基づいてデータ通信量の期待値等も算出してもよい。M2MサービスPF27は、このようにして算出した統計情報をネットワークアシスト情報として中継装置26へ通知してもよい。
続いて、M2MサービスPF27から中継装置26へ通知するネットワークアシスト情報について実施の形態5とは異なる例について説明する。M2MサービスPF27は、複数のM2Mデバイス21をグループ単位で管理し、グループにおける通信特性等の変化をネットワークアシスト情報として検知してもよい。例えば、M2Mデバイスが所属する企業ごとにグループを設定してもよく、そのほかに、M2Mデバイスの加入者情報に基づいてグループを設定してもよい。
以上説明したようにM2Mデバイスをグループ分けした場合、M2MサービスPF27は、中継装置26へネットワークアシスト情報とともにグループを識別するグループ識別子を通知する。グループがM2Mデバイスの位置する場所に応じて定められている場合、M2Mデバイスが位置するエリアを識別するエリア識別子を合わせて中継装置26へ通知してもよい。また、グループがM2Mデバイスが通信を開始する時間に応じて定められている場合、時間帯を識別する時間帯識別子を合わせて中継装置26へ通知してもよい。
続いて、図15を用いて本発明の実施の形態5にかかるネットワークの構成例について説明する。本図においては、移動通信事業者が、3GPP(3rd Generation Partnership Project)において規定された移動通信ネットワークを用いる例について説明する。本図においては無線アクセスNW装置71、HSS77、MME(Mobility Management Entity)72、S-GW(Serving Gateway)75及びP-GW(Packet Data Network Gateway)76は、NWノード23に相当する。また、NWノード23は、3GPPにきていされているノード装置であるPCRFを含んでもよい。
続いて、図26を用いて、移動通信装置11が検知した自装置の状態変化に基づいて生成したネットワークアシスト情報をサービスプラットフォーム13を介さずにネットワークオペレータ装置12へ通知する例について説明する。図26においては、移動通信装置11の具体例として、UE(User Equipment)を用い、ネットワークオペレータ装置12の具体例として、eNB、MME、S-GW、P-GW、PCRF、HSS、MTC-IWF及びSCSを用いて説明する。
また、eNBは、ステップS32において、端末挙動変化通知メッセージを受信し、特性変化情報に応じてNWパラメータの変更が必要であると判定した場合、自装置のNWパラメータを変更してもよい。
