【００５８】
携帯電話機設定データ記録部４５は、携帯電話機２の携帯電話機設定データ記録部２５に記録されているのと同じ設定データが記録されている。尚、携帯電話機設定データ記録部４５に記録されているデータは、制御部４２により更新可能である。又、携帯電話機設定データ記録部４５は遠隔制御サーバ４からアクセス可能であれば良く、ネットワーク３に接続可能な外部サーバ内にあっても良い。この場合、電池情報データベース４３等の遠隔制御サーバ４が取得する他のデータ群についても、上記外部サーバ内にあることが望ましい。
【００５９】
制御部４５は各部を制御するものであり、トリガ情報制御部４２１、制御内容決定部４２２、及び遠隔制御実行部４２３を備える。
【００６０】
トリガ情報制御部４２１は、携帯電話機２の遠隔制御を開始するためのトリガとなるトリガ情報を予め定められた所定タイミング毎（例えば、１２時間間隔）に生成し、生成したトリガ情報を通信部４１から携帯電話機２に対して送信する。制御内容決定部４２２は、携帯電話機２から送信されてきた電池残量情報と、電池情報データベース４５に記録されているデータとに基づいて、例えば、携帯電話機２のアプリケーションプログラムの実行時間を決定し、携帯電話機設定データ記録部４５に記録されているアプリケーションプログラムの実行時間を、決定した実行時間に更新する。
【００６１】
遠隔制御実行部４２３は、携帯電話機設定データ記録部４５に記録されている設定データに基づいて携帯電話機２の遠隔制御を行う。例えば、携帯電話機設定データ記録部４５に記録されている携帯電話機２のアプリケーションプログラムの実行時間がＸ秒に変更された場合、携帯電話機２内の携帯電話機設定データ記録部２５に記録されているアプリケーションプログラムの実行時間の設定データをＸ秒に更新するための制御信号を生成し、生成した信号を通信部４１を介して携帯電話機２に送信する。
【００６２】
以上が、遠隔制御システム１００の各構成要素の説明である。次に、遠隔制御システム１００の処理の流れについて説明する。
図２は、本発明の第一実施形態に係る遠隔制御システムの処理の流れを説明するためのシーケンスチャートである。
【００６３】
遠隔制御サーバ４は、携帯電話機２の遠隔制御を開始する時間になると（Ｓ２０１）、遠隔制御を開始することを示すトリガ情報を携帯電話機２に送信する（Ｓ２０２）。携帯電話機２ではトリガ情報を受信すると、トリガ情報受信時点での自機の電池残量情報を取得し（Ｓ２０３）、取得した電池残量情報をトリガ情報の返信として遠隔制御サーバ４に送信する（Ｓ２０４）。
【００６４】
遠隔制御サーバ４は電池残量情報を受信すると、この電池残量情報と電池情報データベース４３に記録されているデータとに基づいて携帯電話機２の制御内容を決定する（Ｓ２０５）。制御内容決定後、携帯電話機設定データ記録部４５の設定データを更新し（Ｓ２０６）、携帯電話機２の設定データを更新するための制御信号を生成する（Ｓ２０７）。生成した制御信号は携帯電話機２に送信され（Ｓ２０８）、携帯電話機２の制御部２２により設定データが更新される（Ｓ２０９）。携帯電話機２内の設定データ更新後は、その更新後の設定データに基づいて、アプリケーションプログラムが実行される。
【００６５】
次に、Ｓ２０５の制御内容の決定方法の具体例を説明する。
図３は、本発明の第一実施形態に係る遠隔制御システムの遠隔制御サーバにおける制御内容決定処理の流れを説明するためのフローチャートである。尚、ここでは、携帯電話機２がＰ社製のものであり、その電池残量が４２であった場合の例について説明する。
【００６６】
まず、遠隔制御サーバ４は、電池情報データベース４３から携帯電話機２の電池容量情報を取得する（Ｓ３０１）。ここでは、携帯電話機２がＰ社製なので、電池はＡとなり、その容量は１２０である。次に、取得した電池容量と電池残量情報とから電池残量比率を算出する（Ｓ３０２）。ここでは、電池残量比率Ｙ＝（４２／１２０）×１００＝３５％である。
【００６７】
遠隔制御サーバ４は、電池情報データベース４３のテーブルｃを参照して、電池残量比率が５０％より大きければ（Ｓ３０３：ＹＥＳ）、携帯電話機２のアプリケーションプログラムの実行時間を、予め設定されているデフォルトの実行時間の１倍に決定する（Ｓ３０４）。一方、電池残量比率が５０％以下の場合（Ｓ３０３：ＮＯ）、その電池残量比率が２０％以上かどうか判断する。２０％より小さい場合（Ｓ３０５：ＹＥＳ）、携帯電話機２のアプリケーションプログラムの実行時間を、予め設定されているデフォルトの実行時間の０．３倍に決定する（Ｓ３０６）。一方、２０％以上の場合（Ｓ３０５：ＮＯ）、アプリケーションプログラムの実行時間を、予め設定されているデフォルトの実行時間の０．５倍に決定する（Ｓ３０７）。
【００６８】
以上のように本実施形態によれば、遠隔制御サーバ４が携帯電話機２の遠隔制御を開始する際に、携帯電話機２の電池残量情報を取得し、取得した電池残量情報に応じて制御内容を決定する。このため、携帯電話機２の状態に応じた遠隔制御を行うことができ、携帯電話機２の電池残量が少ない場合はアプリケーションプログラムの実行時間を短くして電力消費を抑えるように遠隔制御したり、充分に電池残量がある場合はデフォルトの実行時間に設定したりすることができる。
【００６９】
又、携帯電話機２は、自身の電池残量に応じて遠隔制御サーバ４からの遠隔制御を受けるため、電力消費を抑えることができ、待受時間の延長等の効果を得ることができる。
【００７０】
尚、電池残量比率は遠隔制御サーバ４で算出せずに、携帯電話機２の電池管理部２３で求めておくようにしても良い。この場合は、携帯電話機２は、トリガ情報の返信として電池残量比率の情報を遠隔制御サーバ４に送信する。
【００７１】
（第二実施形態）
本発明の第二実施形態に係る遠隔制御システムでは、遠隔制御サーバ４による制御内容の決定を、電池残量情報だけでなく、携帯電話機２で実行されているアプリケーションプログラムの優先度も考慮して行う構成となっている。
【００７２】
図４は、本発明の第二実施形態に係る遠隔制御システムの構成図である。
本実施形態に係る遠隔制御システム２００は、第一実施形態で説明した携帯電話機２の構成に、携帯電話機２で実行中のアプリケーションプログラムを監視する監視部２７を追加し、第一実施形態で説明した遠隔制御サーバ４の構成に、携帯電話機２で実行可能なアプリケーションプログラムに関する情報を記録するアプリケーションプログラム情報データベース４４（以下、アプリケーションプログラム情報ＤＢという）を追加したものである。図１と同様の構成には同一符号を付して説明を省略する。
【００７３】
監視部２７は、携帯電話機２で実行中のアプリケーションプログラムを監視し、その実行中のアプリケーションプログラムのＩＤ情報を取得する。状態情報取得部２４は、電池残量情報に加え、監視部２７で取得されたＩＤ情報を取得する。制御部２２は、電池残量情報とＩＤ情報とを携帯電話機２の状態情報として通信部２１を介して遠隔制御サーバ４に送信するよう制御する。
【００７４】
アプリケーションプログラム情報ＤＢ４４には、携帯電話機２で実行可能なアプリケーションプログラムのＩＤ情報とそのアプリケーションプログラムの優先度とを対応付けた以下に示すような優先度判定テーブルが記録されている。尚、アプリケーションプログラムの優先度は５段階であり、優先度の最大値は５、最小値は０である。又、アプリケーションプログラム情報ＤＢ４４は、ネットワーク３に接続可能な外部サーバにあっても良い。
【００７５】
【表４】

【００７６】
制御内容決定部４２２は、携帯電話機２から受信したＩＤ情報と優先度判定テーブルとに基づいて、携帯電話機２で実行中のアプリケーションプログラムの優先度を判定し、その優先度も考慮して制御内容を決定する。
【００７７】
第二実施形態に係る遠隔制御システム２００の処理の流れは、遠隔制御サーバ４が電池残量情報に加えて、携帯電話機２で実行中のアプリケーションプログラムの優先度を考慮してアプリケーションプログラムの実行時間を決定する以外は第一実施形態と同様である。以下、アプリケーションプログラムの優先度に応じてアプリケーションプログラムの実行時間を決定する例について説明する。
【００７８】
図５は、本発明の第二実施形態に係る遠隔制御システムの遠隔制御サーバにおける制御内容決定処理の流れを説明するためのフローチャートである。図３と同様のフローには同一符号を付して説明を省略する。
【００７９】
遠隔制御サーバ４は、Ｓ３０２で電池残量比率を算出後、受信したＩＤ情報と優先度判定テーブルとに基づいて、携帯電話機２で実行中のアプリケーションプログラムの優先度を判定する（Ｓ５０８）。判定の結果、優先度が最大の５であった場合（Ｓ５０８：ＹＥＳ）、Ｓ３０４へと処理を移行する。一方、優先度が０〜４であった場合（Ｓ５０８：ＮＯ）、Ｓ３０３へと処理を移行する。
【００８０】
以上のように本実施形態によれば、優先度が高い、つまり、携帯電話機２の動作において非常に重要なアプリケーションプログラム（例えば、発信電波の出力制御アプリケーションプログラムやスケジュールアラーム起動アプリケーションプログラム等）が携帯電話機２で実行されている場合には、電池残量に関わらず、そのアプリケーションプログラムの実行時間をデフォルトの時間に決定する。このため、携帯電話機２の電池残量が少ないからといって、重要なアプリケーションプログラムの実行時間を短くしてしまうといった事態を避けることができ、携帯電話機２の動作の信頼性を確保することができる。
【００８１】
尚、Ｓ５０８における優先度の判定処理は、Ｓ２０４で電池残量情報とＩＤ情報とを受信した直後に行うようにしても良い。これにより、優先度が高いアプリケーションプログラムを実行中の携帯電話機２については、電池残量の算出を行わずに制御内容を決定できるため、遠隔制御を開始するまでの時間を短縮することができる。
【００８２】
（第三実施形態）
図６は、本発明の第三実施形態に係る遠隔制御システムの構成図である。図２と同様の構成には同一符号を付して説明を省略する。
【００８３】
本発明の第三実施形態に係る遠隔制御システム３００は、第一又は第二実施形態で説明した遠隔制御システムの遠隔制御サーバ４の構成に、制御内容決定部４２２が算出した電池残量比率を履歴として記録する履歴情報記録部４６を追加したものである。
【００８４】
履歴情報記録部４６には、以下に示すような電池残量情報履歴テーブルが記録される。電池残量情報履歴テーブルには、遠隔制御サーバ４が携帯電話機２の制御を行うためのトリガ情報を送信する度に携帯電話機２から送信されてくる電池残量情報を取得した時間と、取得した電池残量情報に基づいて算出した電池残量比率とが対応付けて記録される。
【００８５】
【表５】

【００８６】
次に、本実施形態に係る遠隔制御システム３００の処理の流れについて説明する。
図７は、本発明の第三実施形態に係る遠隔制御システムの処理の流れを説明するためのシーケンスチャートである。図２と同様のシーケンスには同一符号を付して説明を省略する。
【００８７】
遠隔制御サーバ４は、Ｓ２０８で制御信号を送信後、算出した電池残量比率を履歴として履歴情報記録部４６に記録する（Ｓ７１１）。そして、トリガ情報制御部４２１が、履歴情報記録部４６に記録されている電池残量比率の履歴に応じて、次回の遠隔制御開始のタイミング（トリガ情報を携帯電話機２に送信する時刻）を決定する（Ｓ７１２）。
【００８８】
図８は、本発明の第三実施形態に係る遠隔制御システムの遠隔制御サーバの遠隔制御開始タイミング決定処理の流れを説明するためのフローチャートである。
遠隔制御サーバ４は、履歴情報記録部４６に記録されている履歴情報を参照し（Ｓ８０１）、履歴情報のうち、今回記録した電池残量比率の情報と、前回の遠隔制御時に記録した電池残量比率の情報とを比較する。比較の結果、今回の電池残量比率が前回の電池残量比率よりも大きかった場合（Ｓ８０２：ＹＥＳ）、遠隔制御サーバ４は、次回の遠隔制御開始の時刻をデフォルトの時刻（１２時間後）に決定する。
【００８９】
一方、今回の電池残量比率が前回の電池残量比率よりも小さかった場合（Ｓ８０２：ＮＯ）、遠隔制御サーバ４は、更に、今回の電池残量比率が１０％より小さいか否かを判定する。判定の結果、今回の電池残量比率が１０％より大きい場合（Ｓ８０３：ＮＯ）、電池残量比率に対応する重み数値に応じて、次回の遠隔制御開始時刻をデフォルトの時刻よりも後の時刻に決定する。つまり、遠隔制御を行う時間間隔をデフォルトよりも長くする（例：重み１→１２時間後、重み０．５→１８時間後）。
【００９０】
一方、今回の電池残量比率が１０％より小さい場合（Ｓ８０３：ＹＥＳ）、次回の遠隔制御開始時刻を、携帯電話機２の電池がなくなってしまう電池切れ予測時刻に決定する。この電池切れ予測時刻は、携帯電話機２の電池残量が１０％より下回った時点から携帯電話機２の電源が切れるまでの時間を予め統計データとして遠隔制御サーバ４内に記録しておき、この統計データを参照して求める。
【００９１】
以上のように本実施形態によれば、遠隔制御サーバ４が、携帯電話機２の遠隔制御開始時に取得した電池残量情報に基づく電池残量比率を履歴情報記録部４６に記録しておき、前回の遠隔制御時の電池残量比率と今回の遠隔制御時の電池残量比率とに基づいて、次回の遠隔制御開始時刻を決定する。
【００９２】
このため、携帯電話機２の電池残量が少ない場合は、遠隔制御を行う間隔を長くすることで、携帯電話機２の遠隔制御自体が電池を消耗させてしまうといったことが無くなり、待受時間の延長を図ることができる。又、携帯電話機２の電池残量が極端に少ない場合には、その電池残量が最終的になくなってしまうであろう時刻までは遠隔制御を行わないようにするため、携帯電話機２のユーザが、携帯電話機２の電源を切らしたくない状況にある場合に、遠隔制御サーバ４の遠隔制御によって電力が消費され、電源が切れてしまうといったことを無くすことができる。
【００９３】
（第四実施形態）
図９は、本発明の第四実施形態に係る遠隔制御システムの構成図である。図４と同様の構成には同一符号を付して説明を省略する。
図９に示したように、本発明の第四実施形態に係る遠隔制御システム４００は、第一又は第二実施形態で説明した遠隔制御システムの携帯電話機２の構成に、携帯電話機２の動作に関する履歴情報を記録しておく動作履歴情報記録部２８を追加し、遠隔制御サーバ４が、携帯電話機２から送信されてくる動作履歴情報に応じて、次回の遠隔制御開始時刻を決定するようにしたものである。
【００９４】
動作履歴情報記録部２８には、通話履歴情報、不在着信履歴情報、アプリケーションプログラムの使用履歴情報、及び携帯電話機２のキーボタンの押下履歴情報等の携帯電話機２の動作に関する動作履歴情報が記録される。動作履歴情報記録部２８に記録された動作履歴情報は、通信部２１によりトリガ情報を受信した後、状態情報取得部２４により取得され、電池残量情報及びＩＤ情報と共に、携帯電話機２の状態情報として遠隔制御サーバ４に送信される。
【００９５】
遠隔制御サーバ４のトリガ情報制御部４２１は、携帯電話機２から受信した動作履歴情報に基づいて、携帯電話機２の使用傾向を分析し、分析結果に応じて次回の遠隔制御開始時刻を決定する。
【００９６】
次に、本実施形態に係る遠隔制御システム４００の処理の流れについて説明する。
図１０は、本発明の第四実施形態に係る遠隔制御システムの処理の流れを説明するためのシーケンスチャートである。図２と同様のシーケンスには同一符号を付して説明を省略する。図１１は、本発明の第四実施形態に係る遠隔制御システムの遠隔制御サーバで分析された携帯電話機の使用傾向を、縦軸を使用頻度、横軸を時間としてグラフ化したものを示す図である。
【００９７】
携帯電話機２ではトリガ情報を受信すると、トリガ情報受信時点での自機の電池残量情報、ＩＤ情報、及び動作履歴情報を取得し（Ｓ１００３）、取得した電池残量情報、ＩＤ情報、及び動作履歴情報をトリガ情報の返信として遠隔制御サーバ４に送信する（Ｓ１００４）。その後、遠隔制御サーバ４は、Ｓ２０８で制御信号を送信後、携帯電話機２から受信した動作履歴情報に基づいて、携帯電話機２のユーザの携帯電話機２の使用傾向を分析する（Ｓ１０１１）。分析の結果、携帯電話機２の使用傾向は図１１に示したようになっているため、遠隔制御サーバ４は、次回の遠隔制御開始時刻が、ユーザが特に携帯電話機２を使用する時間帯（１２時〜２４時）に設定されているか否か判定する。判定の結果、次回の遠隔制御開始時刻が１２時〜２４時の間に設定されている場合（Ｓ１０１２：ＮＯ）、次回の遠隔制御開始時刻を、ユーザが携帯電話機２を使用していない０時〜１２時までの時間帯のいずれかの時刻に決定する（Ｓ１０１３）。一方、次回の遠隔制御開始時刻が０時〜１２時の間に設定されているときは（Ｓ１０１２：ＹＥＳ）、そのまま処理をＳ２０１へと移行する。
【００９８】
以上のように本実施形態によれば、遠隔制御サーバ４が携帯電話機２の遠隔制御開始時に取得した携帯電話機２の動作履歴情報に基づいて、ユーザの携帯電話機２の使用傾向を分析し、分析結果に応じて、次回の遠隔制御開始時刻を決定する。
【００９９】
このため、ユーザが携帯電話機２を使用していない時間帯のいずれかの時刻を次回の遠隔制御開始時刻とすることで、携帯電話機２の電池があまり消費されていない時間帯に、携帯電話機２の遠隔制御を行うことができる。したがって、携帯電話機２が頻繁に使用されている時間帯に遠隔制御が行われて、携帯電話機２の電源が切れてしまうといったことを防ぎながら、遠隔制御を行うことができる。又、携帯電話機２については、待受時間の延長を図ることが可能となる。
【０１００】
（第五実施形態）
本発明の第五実施形態に係る遠隔制御システムは、第一〜第四実施形態のいずれかで説明した遠隔制御システムにおいて、制御内容として、アプリケーションプログラムの実行時間の変更を行うこと以外に、携帯電話機２が接続中のゲートウェイ（ＧＷ）サーバを、その混雑状況に応じて別のＧＷサーバに切替えるようにしたものである。
【０１０１】
図１２は、本発明の第五実施形態に係る遠隔制御システムの構成図である。図１と同様の構成には同一符号を付して説明を省略する。
本発明の第五実施形態に係る遠隔制御システムは、図１に示した携帯電話機２の構成に接続先監視部２９を追加し、遠隔制御サーバ４の制御部４２の構成にサーバ混雑状況取得部４２４を追加し、更に、遠隔制御システム全体に、ネットワーク３に接続可能な混雑状況監視サーバ７を備えたものである。
【０１０２】
本実施形態に係る携帯電話機２の通信部２１は、あるウェブサーバと通信を行う場合、携帯電話機設定データ記録部２５に記録されているＧＷアドレスに対応するＧＷサーバを経由してウェブサーバと通信を行う。
【０１０３】
接続先監視部２９は、携帯電話機２の接続先を監視し、接続中のＧＷサーバのＧＷアドレス情報を取得する。ここで取得されたＧＷアドレス情報は、通信部２１によりトリガ情報を受信すると、状態情報取得部２４により取得され、電池残量情報と共に携帯電話機２の状態情報として遠隔制御サーバ４に送信される。
【０１０４】
混雑状況監視サーバ７は、ネットワーク３に接続可能なウェブサーバと、そのウェブサーバを中継するＧＷサーバの混雑状況を監視し、その混雑状況を示す混雑状況情報を内部のメモリ等に記録する。
【０１０５】
遠隔制御サーバ４のサーバ混雑状況取得部４２４は、携帯電話機２から受信したＧＷアドレス情報に対応するＧＷサーバの混雑状況情報を混雑状況監視サーバ７から取得する。
【０１０６】
制御内容決定部４２２は、サーバ混雑状況取得部４２４で取得した混雑状況情報に応じて、携帯電話機２の接続先のＧＷサーバのアドレスを別のＧＷサーバのアドレスに決定し、携帯電話機設定データ記録部４５の設定データを更新する。遠隔制御実行部４２３は、更新後の携帯電話機設定データ記録部４５の設定データに基づいて、携帯電話機２の接続先のゲートウェイアドレスを更新するための制御信号を生成し、携帯電話機２に送信する。尚、この制御信号は、携帯電話機２のアプリケーションプログラムの実行時間を更新するための制御信号と同時でも良いし、別々に送信しても良い。
【０１０７】
次に、本実施形態に係る遠隔制御システム５００の処理の流れについて説明する。
図１３は、本発明の第四実施形態に係る遠隔制御システムの処理の流れを説明するためのシーケンスチャートである。図２と同様のシーケンスには同一符号を付して説明を省略する。
【０１０８】
携帯電話機２ではトリガ情報を受信すると（Ｓ２０２）、トリガ情報受信時点での自機の電池残量情報と接続先のＧＷアドレス情報とを取得し（Ｓ１３０３）、取得した電池残量情報と接続先のＧＷアドレス情報をトリガ情報の返信として遠隔制御サーバ４に送信する（Ｓ１３０４）。その後、遠隔制御サーバ４は、Ｓ２０５で、電池残量情報に基づいて制御内容を決定後、携帯電話機２が接続しているＧＷサーバの混雑状況情報を取得する（Ｓ１３１２）。遠隔制御サーバ４は、携帯電話機２が接続しているＧＷサーバが混雑していると判断した場合（Ｓ１３１３：ＹＥＳ）、携帯電話機２の通信接続先のＧＷサーバのアドレスを、当該ＧＷサーバを経由して接続可能なウェブサーバのミラーサーバを中継するＧＷサーバのＧＷアドレスに決定し（Ｓ１３１４）、携帯電話機設定データ記録部４５の設定データを更新する（Ｓ２０６）。そしてＳ２０７で、ＧＷアドレスを更新するための制御信号を生成して携帯電話機２に送信する。制御信号を受信した携帯電話機２では、遠隔制御サーバ４から指定されたＧＷアドレスに対応するＧＷサーバに接続先を切替える（Ｓ１３１５）。
【０１０９】
図１４は、本発明の第五実施形態に係る遠隔制御システムにおいて、携帯電話機の接続先を変更する際の処理の流れを概念的に示した図である。同図に示したように、ネットワーク３にはウェブサーバ４０を中継するＧＷサーバ１０及び２０と、ウェブサーバ４０のミラーサーバであるウェブサーバ５０を中継するＧＷサーバ３０とが接続されている。
【０１１０】
図１４に示したように、遠隔制御サーバ４がトリガ情報を携帯電話機２に送信した際に、携帯電話機２は自機が接続中のＧＷサーバ１０又は２０のＧＷアドレス情報を取得し、遠隔制御サーバ４に送信する。遠隔制御サーバ４では、受信したＧＷアドレス情報に対応するＧＷサーバの混雑状況情報を混雑状況監視サーバ７から取得する。ここでは、ＧＷサーバ１０及び２０が混雑中であるため、携帯電話機２の接続先をＧＷサーバ１０又は２０からＧＷサーバ３０に切替えるように遠隔制御を行う。これにより、携帯電話機２は接続先をＧＷサーバ３０に切替え、ウェブサーバ５０に接続する。
【０１１１】
以上のように本実施形態によれば、遠隔制御サーバ４の制御内容として、携帯電話機２が接続中のＧＷサーバの混雑状況情報に基づいて、携帯電話機２の接続先を切替える。このため、携帯電話機２は、混雑したＧＷサーバ又はウェブサーバへの接続を避けることができるため、ストレスのないウェブ閲覧が可能となる。
【０１１２】
尚、携帯電話機２が複数存在する場合、遠隔制御サーバ４のトリガ情報の送信タイミングは、第三又は第四実施形態で説明したトリガ情報制御部４２１によって決定されたタイミングではなく、混雑状況監視サーバ７から混雑状況情報を受信したときであっても良い。このようにすることで、サーバが混雑しているときのみに、複数の携帯電話機の接続先を変更可能なため、遠隔制御サーバ４にとって無駄な通信を削減することができる。
【０１１３】
又、遠隔制御サーバ４は、混雑状況監視サーバ７から混雑状況情報を受信したときに、遠隔制御対象となる全ての携帯電話機に対してトリガ情報を送信するのではなく、携帯電話機設定データ記録部４５に記録されている各携帯電話機のＧＷアドレス情報と、混雑状況監視サーバ７から受信した混雑状況情報とに基づいて、複数の携帯電話機のうち、混雑しているＧＷサーバのＧＷアドレス情報が設定されている携帯電話機のみに対してトリガ情報を送信するようにしても良い。このようにすることで、混雑しているＧＷサーバに接続するように設定されている携帯電話機にのみトリガ情報が送信されるため、無駄な通信が発生せず、システム全体のパフォーマンスを向上させることができる。
【０１１４】
又、本実施形態では、遠隔制御の具体例として、携帯電話機２で設定されているＧＷアドレス情報を変更する制御について説明したが、ＧＷアドレス情報の変更制御以外に、携帯電話機２の接続先の情報として、携帯電話機２に予め設定されているデフォルトＵＲＬや緊急連絡先電話番号等の変更制御を遠隔制御サーバ４が行うようにしても良い。これは、例えば、災害等の緊急時に、携帯電話機２のユーザが、緊急時に備えて携帯電話機２に予め登録している電話番号（緊急連絡先電話番号）に発信したり、デフォルトのＵＲＬにアクセスして情報を取得したりする状況を想定した場合に効果的である。
【０１１５】
つまり、緊急時には、携帯電話機２の接続先の基地局やサーバ（ＧＷサーバ、ウェブサーバ）が混雑することが予測されるが、本実施形態のように、遠隔制御サーバ４がネットワーク３上のサーバの混雑状況を把握し、その混雑状況に応じて携帯電話機２に設定されている緊急連絡先番号やデフォルトＵＲＬを変更するよう遠隔制御することで、携帯電話機２のユーザは、最も空いている基地局やサーバを介して緊急時の連絡や情報収集が可能となる。これにより、緊急時に、どこにも連絡ができなくなってしまうといった危険性を回避することが可能となる。
【０１１６】
（第六実施形態）
本実施形態の遠隔制御システムは、第一〜第五実施形態のいずれかで説明した携帯電話機２を持つ、予め定めた複数のユーザが山間部等で遭難してしまった状況を想定したものである。図１５は、本発明の第六実施形態に係る遠隔制御システムの構成図である。図１と同様の構成には同一符号を付して説明を省略する。
【０１１７】
本発明の第六実施形態に係る遠隔制御システムは、第一〜第五実施形態で説明した携帯電話機２を複数備え、複数の携帯電話機２の各々の構成に、携帯電話機２のユーザの体温情報等のユーザに関するユーザ情報を取得するユーザ情報取得部３０（体温センサ等）、携帯電話機２の置かれている周囲の気温や気圧等の周辺環境に関する周辺環境情報を取得する周辺環境情報取得部３１（気温・気圧センサ等）とを追加し、遠隔制御サーバ４の構成に、携帯電話機２から受信した各種情報を複数の携帯電話機２毎に記録する情報記録部４７を追加し、制御部４２に優先度判定部４２５を追加したものである。
【０１１８】
ユーザ情報取得部３０で取得されたユーザ情報及び周辺環境情報取得部３１で取得された周辺環境情報は、電池残量情報と共に遠隔制御サーバ４に送信される。
【０１１９】
情報記録部４７には、以下に示すような、状態情報を取得した携帯電話機の機種、その電池残量比率、そのユーザの体温、その周辺の気温等をまとめた情報管理テーブルが記録される。
【０１２０】
【表６】

【０１２１】
優先度判定部４２５は、複数の携帯電話機２の各々から受信したユーザ情報及び周辺環境情報を比較し、遠隔制御を優先的に行うべき携帯電話機２を判定する。例えば、情報記録部４７に記録されている情報管理テーブルを参照し、最も体温が低いユーザの所持する携帯電話機２の優先度を最高とする。体温が同じユーザが存在する場合は、電池残量比率が低い方の優先度を高くする。
【０１２２】
優先度判定部４２５による判定結果により、遠隔制御サーバ４のオペレータは、優先度が所定値を超えた携帯電話機２のユーザに対しては、救助隊等を優先的に手配するといった指示を下すことが可能となる。
【０１２３】
遠隔制御実行部４２３は、優先度判定部４２５で遠隔制御を優先的に行うべきと判定された携帯電話機２についてのみ、第一〜第五実施形態のいずれかで示した内容の遠隔制御（アプリケーションプログラムの実行時間の変更やＧＷアドレスの変更）を行ったり、遠隔制御の開始タイミングを変更したり、その携帯電話機２に救援の指示を示したメッセージ情報を送信したりする。
【０１２４】
次に、本実施形態に係る遠隔制御システム６００の処理の流れについて説明する。
図１６は、本発明の第六実施形態に係る遠隔制御システムの処理の流れを説明するためのシーケンスチャートである。図２と同様のシーケンスには同一符号を付して説明を省略する。
【０１２５】
携帯電話機２ではトリガ情報を受信すると、トリガ情報受信時点での自機の電池残量情報、自機のユーザの体温情報、及び自機の周辺の気温・気圧情報を取得し（Ｓ１６０３）、取得した電池残量情報、体温情報、及び気温・気圧情報を、トリガ情報の返信として遠隔制御サーバ４に送信する（Ｓ１６０４）。
【０１２６】
遠隔制御サーバ４は電池残量情報、体温情報、及び気温・気圧情報を受信すると、これらの情報を情報記録部４７に記録する（Ｓ１６０５）。遠隔制御サーバ４では、予め定めたユーザの所持する複数の携帯電話機２の全てからの上記情報を情報記録部４７に記録すると、複数の携帯電話機２の情報の各々を比較して、それぞれの携帯電話機２について優先度を決定する（Ｓ１６０６）。優先度を決定後、優先度が所定値を越えた携帯電話機２に対してのみ、上記情報に含まれる電池残量情報に基づいて制御内容が決定される（Ｓ２０５）。
【０１２７】
以上のように本実施形態によれば、遠隔制御サーバ４が携帯電話機２の遠隔制御開始時に、携帯電話機２に関する情報として、複数の携帯電話機２のユーザの各々に関するユーザ情報を取得し、このユーザ情報と電池残量情報とに基づいて、各携帯電話機又はそのユーザに優先度を付ける。
【０１２８】
このため、優先度が高いユーザ、例えば体温が非常に低下しているユーザに対しては優先的に救助隊を向かわせることができる。又、優先度が高いユーザに対してのみ、携帯電話機２の消費電力を抑えるような制御信号を送信するため、体温が低下しているユーザとの連絡をとるための時間を長く確保することができる。したがって、山間部等での遭難における救助活動を効率的に行うことが可能となる。
【０１２９】
尚、本実施形態では携帯電話機２の電池残量情報、ユーザ情報、及び周辺環境情報を用いて優先度を判定したが、電池残量情報は必ずしも必要ではない。ユーザを救助するという目的のためには、ユーザ情報及び周辺環境情報があれば、ユーザに対する優先度付けを行うことができる。
【０１３０】
又、携帯電話機２に関する情報としては、携帯電話機２に内蔵されたカメラによって撮影された画像情報や携帯電話機２の位置情報を含ませても良い。これにより、携帯電話機２のユーザの置かれている状況をより詳しく知ることができ、優先度付けを精度良く行うことができる。
【０１３１】
又、以上の説明では、遠隔制御サーバ４が、携帯電話機２から送信されてくるユーザ情報及び周辺環境情報等に基づいて各携帯電話機の優先度を決定する構成としたが、携帯電話機２から送信されてくる情報に依存せず、遠隔制御サーバ４側で所定の要件を満たす携帯電話機には全て強制的に優先度を高く設定するようにしても良い。
【０１３２】
又、本実施形態では、遠隔制御実行部４２３が、優先度が閾値を越えた携帯電話機のみに対して遠隔制御を行う構成としたが、この閾値を設けずに、各携帯電話機の優先度をソートして、優先度が高い順番に全ての携帯電話機を遠隔制御するようにしても良い。更に、各携帯電話機の優先度を決定した後は、第一〜第五実施形態で説明したように、各携帯電話機の電池残量情報、即ち、状態情報に基づいて制御内容を決定する構成となっているが、状態情報以外に、周辺環境情報やユーザ情報をも考慮して制御内容を決定して遠隔制御するようにしても良い。以下、この場合の制御例について具体例をあげて説明する。
【０１３３】
＜周辺環境情報を考慮した制御例＞
ここでは、携帯電話機から送信されてくる周辺環境情報として、上記のように携帯電話機２に内蔵されたカメラによって撮影された画像情報が含まれる例について説明する。
１．遠隔制御サーバ４が受信した周辺環境情報に含まれる画像情報に基づく画像の輝度が低い場合（夜間、地下、トンネル等で撮影された場合）：撮影時に携帯電話機に搭載されたストロボを発光させるための制御信号を携帯電話機に送信する。但し、電池残量が少なくなっている場合には、撮影時にストロボを発光させないような制御信号を送信する。
２．遠隔制御サーバ４が受信した周辺環境情報に含まれる画像情報に基づく画像のピントがずれている場合：携帯電話機に搭載されたカメラのピントを制御するための制御信号を携帯電話機に送信する。これも同様、電池残量が少ない場合はピント制御を禁止するような制御信号を送信する。
３．レンズを回転させることが可能な駆動装置が付いているカメラを搭載する携帯電話機から画像情報を受信した場合：携帯電話機に搭載された駆動装置を撮影時に動作させて、カメラのレンズを回転させるための制御信号を送信する。これも同様、電池残量が少ない場合は駆動装置の動作を禁止するような制御信号を送信する。
【０１３４】
以上のような制御を行うことにより、電池残量とカメラで撮影した画像情報（周辺環境情報）とに基づいてカメラの制御を行うことができる。これは、緊急時等でカメラの操作を上手くできないような状況に置かれたユーザ等に効果的である。ユーザが、ストロボ発光やピント合わせ等の細かい設定ができない状況下にあっても、遠隔制御サーバ４からの遠隔制御によりストロボ発光やピント制御を行うことができる。このため、遠隔制御後に再度ユーザがカメラにより撮影を行った場合、より鮮明な画像情報を遠隔制御サーバ４に送信することができ、緊急時のユーザの救助等に役立てることができる。
【０１３５】
又、本実施形態では、遠隔制御サーバ４がユーザ情報及び周辺環境情報を受信した後、各携帯電話機の優先度を決定し、その優先度に基づいて携帯電話機の遠隔制御を行うが、この遠隔制御を行う際に遠隔制御サーバ４から遠隔制御対象の携帯電話機に送信する制御信号として、携帯電話機のアイコンの配置を変更するための変更制御信号（携帯電話機の画面上に、簡単な操作で緊急連絡先に発信できるようなアイコンを生成させるための信号）や携帯電話機の初期画面変更信号（携帯電話機の初期画面を緊急時用の画面に変更させるための信号）等も考えられる。この場合について図１７を参照して説明する。
【０１３６】
図１７は、本発明の第六実施形態に係る携帯電話機の画面表示例を示す図であり、（ａ）は初期画面、（ｂ）は緊急時の優先度が高い場合の画面、（ｃ）は緊急時の優先度が低い場合の画面を示す図である。
図１７に示したように、携帯電話機２の初期画面上には、ゲーム、メール、ブラウザ、カレンダー、メインメニュー、電話帳、及び各種設定等のアイコンが９つ表示される。
【０１３７】
ここでは、災害等の緊急時において、遠隔制御サーバ４によって決定された各携帯電話機の優先度が高い程、その携帯電話機が緊急を要する状況にあるものとする。この場合、遠隔制御サーバ４は、優先度の高い携帯電話機２に対しては、該携帯電話機２の画面を図１７に示した（ａ）から（ｂ）に強制的に変更させるための初期画面変更制御信号を送信する。一方、優先度が低い（すなわち、緊急度が低い）携帯電話機２に対しては、該携帯電話機２の画面を図１７に示した（ａ）から（ｃ）に強制的に変更させるための初期画面変更制御信号を送信する。
【０１３８】
図１７に示した画面（ｂ）及び（ｃ）について説明する。
図１７（ｂ）に示した画面には、緊急連絡発信アイコン、救援状況を知らせるアイコン、及び緊急用の電波を発信していることを示すアイコンが表示される。ユーザは、緊急連絡発信アイコンを選択して決定することで、遠隔制御サーバ４によって変更された緊急連絡先電話番号又は予め設定されている緊急連絡先番号に発信することができる。図１７（ｃ）に示した画面には、緊急時であることを通知する各種アイコン（緊急指定地域の通知アイコン、緊急避難場所の通知アイコン、通行規制の通知アイコン）が表示される。尚、各種アイコンを選択して決定することで、より詳細な情報が表示されるようにしても良い。
【０１３９】
又、遠隔制御対象となる携帯電話機の地理的場所は、およそ、その携帯電話機の送受信する電波をカバーする基地局の位置により把握することができる。このため、携帯電話機２が遠隔制御サーバ４に送信する周辺環境情報に付随して、その携帯電話機２の電波をカバーする基地局の情報も送り、遠隔制御サーバ４では、その基地局の情報も各携帯電話機の優先度を決定する要因の一つにすることが可能である。これにより、所定の基地局がカバーする電波範囲内に位置する携帯電話機にのみ、携帯電話機のアイコンの配置変更や初期画面変更の制御を行うといったことが可能となる。
【０１４０】
＜ユーザ情報を考慮した制御例＞
ここでは、携帯電話機２から送信されてくるユーザ情報として、携帯電話機２のユーザの体温、脈拍等、ユーザの体調に関する情報が含まれる例について説明する。
この場合、遠隔制御サーバ４は、上記ユーザ情報を取得し、所定の要件（例えば、所定の体温以下、脈拍が所定の回数以下）の場合は、ユーザの生命に危機が生じていると判断し、その携帯電話機２の優先度を高くする。遠隔制御サーバ４では、制御内容決定部４２２がユーザ情報に基づいて制御内容を決定し、優先度が閾値以上又は優先度が高い携帯電話機から順に、以下のように決定された内容の遠隔制御を実行するための制御信号を送信する。携帯電話機２は、受信した制御信号に基づいて動作する。
【０１４１】
制御内容：
（１）診療記録ＤＢへアクセスせよ。
（２）診療記録ＤＢから、その携帯電話機２のユーザに関する診療記録情報をダウンロードせよ。
（３）ダウンロード完了したら、ダウンロードされた診療記録情報にその携帯電話機２から誰でもアクセスできるようなアイコンを画面上に表示せよ。
【０１４２】
ここで、診療記録ＤＢとは、携帯電話機２のユーザが所定期間の間に病院で診療を受けた診療記録（病歴、健康診断結果、使用した薬の情報、薬に関するアレルギー情報、及び担当医等の情報）が保持されたデータベースであり、例えばＦＴＰサーバ内のデータベースを利用する。ＦＴＰサーバは、ネットワーク３に接続されており、携帯電話機２からアクセス可能である。遠隔制御サーバ４の遠隔制御実行部４２３は、上記制御信号と共に、ＦＴＰサーバのアドレス情報を携帯電話機２に送信する。
【０１４３】
携帯電話機２は、遠隔制御サーバ４から送信されてきた制御信号に基づいて次のように動作する。
まず、携帯電話機２は、遠隔制御サーバ４から送られてきた、制御内容（１）を実行するための制御信号とＦＴＰサーバのアドレス情報とに基づいて、ＦＴＰサーバ内の診療記録ＤＢに接続を開始する。尚、ＦＴＰサーバのアドレス情報は、予め携帯電話機内に記録されたものであってもよく、その場合、携帯電話機２は遠隔制御サーバ４から上記制御信号を受信したことをトリガとして、予め格納しているアドレス情報に基づいてＦＴＰサーバへの接続を開始する。この際、携帯電話機２とＦＴＰサーバとの間での認証処理を行っても良い。
【０１４４】
携帯電話機２は、診療記録ＤＢにアクセスすると、制御内容（２）を実行するための制御信号に基づいて、診療記録ＤＢから携帯電話機２のユーザに関する診療記録情報をダウンロードする。携帯電話機２は診療記録情報のダウンロードを完了すると、制御内容（３）を実行するための制御信号に基づいて、遠隔制御サーバ４から指定されたアイコンを画面上に表示する。このアイコンには、例えば「○○さんの通院記録はこちらから」等という情報が表示される。携帯電話機２のユーザ又はその周囲の人間は、このアイコンを選択して実行することで、携帯電話機２のユーザの診療記録を画面上で閲覧することができる。
【０１４５】
以上のような遠隔制御を行うことにより、例えば、災害時等に、携帯電話機２のユーザが、普段通院していない病院に搬送された場合でも、治療を担当する医師は、そのユーザを治療するのに有効な情報をユーザの所持する携帯電話機２を用いて容易に取得することができる。又、そのユーザが意識不明になってしまい、自分自身ではその情報を画面上に表示できない場合であっても、遠隔制御サーバ４からの遠隔制御により、誰でも自由にその情報を見られるようにしておくことができる。
【０１４６】
尚、上記の説明では、携帯電話機２の状態情報について触れていないが、例えば、携帯電話機２の電池残量が極端に少ない場合には、上記のような診療記録をダウンロードさせる遠隔制御を行わないように制御する。この場合には、携帯電話機２から送信されてくる状態情報に基づいて、携帯電話機２の電池残量が多くなったと判断した場合に、上記のような診療記録をダウンロードさせる遠隔制御を行うようにすれば良い。
【０１４７】
又、将来の災害時に備えて、携帯電話機２のメモリ等に診療記録情報を恒常的に記録しておくという形態も想定されるが、診療記録情報等は、本来、プライバシーの観点から秘密にしておくべきものであり、携帯電話機２に保持するようにした場合には、その情報が漏洩することも考えられ、好ましいものではない。一方、上記の形態であれば、遠隔制御サーバ４が、ユーザの身に危機が生じていると判断した場合にのみ、そのユーザの診療記録情報を、ユーザの所持する携帯電話機２にダウンロードするように遠隔制御するため、プライバシーの観点からも効果を有する。
【０１４８】
【発明の効果】

[0048]
The mobile phone 2 includes a communication unit 21, a control unit 22, a battery management unit 23, a state information acquisition unit 24, a mobile phone setting data recording unit 25, and an application program execution unit 26.
[0049]
The communication unit 21 transmits and receives data to and from the remote control server 4. The battery management unit 23 calculates the remaining battery level of the mobile phone 2. Upon receiving an instruction from the control unit 22, the state information acquisition unit 24 acquires the remaining battery amount information calculated by the battery management unit 23 as the state information indicating the state of the mobile phone 2.
[0050]
The mobile phone setting data recording unit 25 records information related to the operation of the application program executable on the mobile phone 2 (information such as the execution time of the application program and the start timing of the application program). The execution time of the application program is, for example, the total time during which a task in the application program takes UI resource resources. The UI resources are hardware resources used for a user interface (User Interface: UI).
[0051]
The application program execution unit 26 executes the application program based on the setting data recorded in the mobile phone setting data recording unit 26.
[0052]
The control unit 22 controls each unit. Further, when receiving the trigger information transmitted from the remote control server 4 by the communication unit 21, the control unit 22 instructs the state information acquisition unit 24 to acquire the remaining battery amount information. Further, the control unit 22 transmits the battery remaining amount information acquired by the state information acquiring unit 24 from the communication unit 21 to the remote control server 4 as a reply of the trigger information. Further, after transmitting the battery remaining amount information, the control unit 22 updates the setting data recorded in the mobile phone setting data recording unit 25 based on the control signal transmitted from the remote control server 4.
[0053]
The remote control server 4 includes a communication unit 41, a control unit 42, a battery information database 43, and a mobile phone setting data recording unit 45.

[0057]
[Table 3]

[0058]
In the mobile phone setting data recording section 45, the same setting data as that recorded in the mobile phone setting data recording section 25 of the mobile phone 2 is recorded. The data recorded in the cellular phone setting data recording section 45 can be updated by the control section 42. The mobile phone setting data recording section 45 may be accessible from the remote control server 4 and may be in an external server connectable to the network 3. In this case, it is desirable that other data groups, such as the battery information database 43, acquired by the remote control server 4 also exist in the external server.
[0059]
The control unit 45 controls each unit, and includes a trigger information control unit 421, a control content determination unit 422, and a remote control execution unit 423.
[0060]
The trigger information control unit 421 generates trigger information serving as a trigger for starting remote control of the mobile phone 2 at predetermined predetermined timings (for example, every 12 hours), and generates the generated trigger information. To the mobile phone 2. The control content determining unit 422 determines, for example, the execution time of the application program of the mobile phone 2 based on the remaining battery level information transmitted from the mobile phone 2 and the data recorded in the battery information database 45. Then, the execution time of the application program recorded in the mobile phone setting data recording unit 45 is updated to the determined execution time.
[0061]
The remote control execution unit 423 performs remote control of the mobile phone 2 based on the setting data recorded in the mobile phone setting data recording unit 45. For example, when the execution time of the application program of the mobile phone 2 recorded in the mobile phone setting data recording unit 45 is changed to X seconds, the application recorded in the mobile phone setting data recording unit 25 in the mobile phone 2 is changed. A control signal for updating the setting data of the program execution time to X seconds is generated, and the generated signal is transmitted to the mobile phone 2 via the communication unit 41.
[0062]
The above is the description of each component of the remote control system 100. Next, a processing flow of the remote control system 100 will be described.
FIG. 2 is a sequence chart for explaining a processing flow of the remote control system according to the first embodiment of the present invention.
[0063]
When it is time to start remote control of the mobile phone 2 (S201), the remote control server 4 transmits trigger information indicating that remote control is to be started to the mobile phone 2 (S202). Upon receiving the trigger information, the mobile phone 2 acquires the battery remaining amount information of the own device at the time of receiving the trigger information (S203), and transmits the acquired battery remaining amount information to the remote control server 4 as a reply of the trigger information (S203). S204).
[0064]
Upon receiving the remaining battery level information, the remote control server 4 determines the control content of the mobile phone 2 based on the remaining battery level information and the data recorded in the battery information database 43 (S205). After the control content is determined, the setting data of the mobile phone setting data recording unit 45 is updated (S206), and a control signal for updating the setting data of the mobile phone 2 is generated (S207). The generated control signal is transmitted to the mobile phone 2 (S208), and the control unit 22 of the mobile phone 2 updates the setting data (S209). After updating the setting data in the mobile phone 2, the application program is executed based on the updated setting data.
[0065]
Next, a specific example of the method of determining the control content in S205 will be described.
FIG. 3 is a flowchart for explaining the flow of control content determination processing in the remote control server of the remote control system according to the first embodiment of the present invention. Here, an example in which the mobile phone 2 is made by Company P and the battery remaining amount is 42 will be described.
[0066]
First, the remote control server 4 acquires the battery capacity information of the mobile phone 2 from the battery information database 43 (S301). In this case, since the mobile phone 2 is made by P, the battery is A and its capacity is 120. Next, a remaining battery ratio is calculated from the acquired battery capacity and remaining battery information (S302). Here, the remaining battery ratio Y = (42/120) × 100 = 35%.
[0067]
The remote control server 4 refers to the table c of the battery information database 43 and sets the execution time of the application program of the mobile phone 2 in advance if the remaining battery ratio is greater than 50% (S303: YES). It is determined to be one time the default execution time (S304). On the other hand, when the remaining battery ratio is 50% or less (S303: NO), it is determined whether the remaining battery ratio is 20% or more. If less than 20% (S305: YES), the execution time of the application program of the mobile phone 2 is determined to be 0.3 times the preset default execution time (S306). On the other hand, if it is not less than 20% (S305: NO), the execution time of the application program is determined to be 0.5 times the preset default execution time (S307).
[0068]
As described above, according to the present embodiment, when the remote control server 4 starts remote control of the mobile phone 2, the remote control server 4 acquires the battery remaining amount information of the mobile phone 2, and performs control according to the obtained battery remaining amount information. Determine the content. For this reason, remote control according to the state of the mobile phone 2 can be performed, and when the battery level of the mobile phone 2 is low, remote control is performed to reduce the power consumption by shortening the execution time of the application program. If there is sufficient remaining battery power, the default execution time can be set.
[0069]
Further, since the mobile phone 2 receives the remote control from the remote control server 4 in accordance with the remaining battery level of the mobile phone 2, the power consumption can be suppressed, and effects such as extension of the standby time can be obtained.
[0070]
Note that the remaining battery ratio may not be calculated by the remote control server 4 but may be obtained by the battery management unit 23 of the mobile phone 2. In this case, the mobile phone 2 transmits information on the remaining battery ratio to the remote control server 4 as a reply of the trigger information.
[0071]
(Second embodiment)
In the remote control system according to the second embodiment of the present invention, the determination of the control content by the remote control server 4 is performed in consideration of not only the battery remaining amount information but also the priority of the application program executed on the mobile phone 2. Configuration.
[0072]
FIG. 4 is a configuration diagram of a remote control system according to the second embodiment of the present invention.
The remote control system 200 according to the present embodiment adds a monitoring unit 27 for monitoring an application program running on the mobile phone 2 to the configuration of the mobile phone 2 described in the first embodiment, and will be described in the first embodiment. An application program information database 44 (hereinafter, referred to as an application program information DB) that records information on application programs executable on the mobile phone 2 is added to the configuration of the remote control server 4 described above. The same components as those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
[0073]
The monitoring unit 27 monitors an application program running on the mobile phone 2 and acquires ID information of the running application program. The state information acquisition unit 24 acquires the ID information acquired by the monitoring unit 27 in addition to the remaining battery amount information. The control unit 22 controls to transmit the remaining battery information and the ID information to the remote control server 4 via the communication unit 21 as the status information of the mobile phone 2.
[0074]
The application program information DB 44 records a priority determination table as shown below, which associates ID information of an application program executable on the mobile phone 2 with the priority of the application program. The priority of the application program has five levels, and the maximum value of the priority is 5 and the minimum value is 0. Further, the application program information DB 44 may be in an external server connectable to the network 3.
[0075]
[Table 4]

[0076]
The control content determining unit 422 determines the priority of the application program running on the mobile phone 2 based on the ID information received from the mobile phone 2 and the priority determination table, and considers the priority to control the content of the application program. To determine.
[0077]
The processing flow of the remote control system 200 according to the second embodiment is such that the remote control server 4 considers the priority of the application program running on the mobile phone 2 in addition to the remaining battery level information, and considers the execution time of the application program. It is the same as the first embodiment except that is determined. Hereinafter, an example in which the execution time of the application program is determined according to the priority of the application program will be described.
[0078]
FIG. 5 is a flowchart for explaining the flow of control content determination processing in the remote control server of the remote control system according to the second embodiment of the present invention. 3 are denoted by the same reference numerals, and description thereof will be omitted.
[0079]
After calculating the remaining battery ratio in S302, the remote control server 4 determines the priority of the application program running on the mobile phone 2 based on the received ID information and the priority determination table (S508). If the result of the determination is that the priority is 5, which is the maximum (S508: YES), the processing moves to S304. On the other hand, when the priorities are 0 to 4 (S508: NO), the process proceeds to S303.
[0080]
As described above, according to the present embodiment, an application program having a high priority, that is, a very important application program in the operation of the mobile phone 2 (for example, an output control application program of a transmission radio wave, a schedule alarm activation application program, and the like) is portable. When the application program is executed on the telephone 2, the execution time of the application program is determined to be a default time regardless of the remaining battery level. For this reason, it is possible to avoid a situation in which the execution time of an important application program is shortened because the remaining battery level of the mobile phone 2 is small, and it is possible to secure the reliability of the operation of the mobile phone 2. it can.
[0081]
Note that the priority determination process in S508 may be performed immediately after the battery remaining amount information and the ID information are received in S204. This allows the mobile phone 2 executing the application program with a high priority to determine the control content without calculating the remaining battery power, thereby shortening the time until remote control is started.
[0082]
(Third embodiment)
FIG. 6 is a configuration diagram of a remote control system according to the third embodiment of the present invention. The same components as those in FIG. 2 are denoted by the same reference numerals and description thereof is omitted.
[0083]
The remote control system 300 according to the third embodiment of the present invention adds the remaining battery ratio calculated by the control content determination unit 422 to the configuration of the remote control server 4 of the remote control system described in the first or second embodiment. A history information recording unit 46 for recording as a history is added.
[0084]
The history information recording unit 46 records a battery remaining amount information history table as described below. In the battery remaining amount information history table, each time the remote control server 4 transmits the trigger information for controlling the mobile phone 2, the time at which the battery remaining amount information transmitted from the mobile phone 2 was obtained, and the obtained time. The remaining battery ratio calculated based on the remaining battery information is recorded in association with the remaining battery ratio.
[0085]
[Table 5]

[0086]
Next, a processing flow of the remote control system 300 according to the present embodiment will be described.
FIG. 7 is a sequence chart for explaining a processing flow of the remote control system according to the third embodiment of the present invention. The same sequences as those in FIG. 2 are denoted by the same reference numerals and description thereof will be omitted.
[0087]
After transmitting the control signal in S208, the remote control server 4 records the calculated remaining battery ratio as a history in the history information recording unit 46 (S711). Then, the trigger information control unit 421 determines the next remote control start timing (time when trigger information is transmitted to the mobile phone 2) according to the history of the remaining battery ratio recorded in the history information recording unit 46. (S712).
[0088]
FIG. 8 is a flowchart for explaining the flow of the remote control start timing determination process of the remote control server of the remote control system according to the third embodiment of the present invention.
The remote control server 4 refers to the history information recorded in the history information recording unit 46 (S801), and among the history information, the information on the remaining battery ratio recorded this time and the remaining battery level recorded during the previous remote control. Compare with the quantity ratio information. As a result of the comparison, if the current battery remaining ratio is larger than the previous battery remaining ratio (S802: YES), the remote control server 4 sets the next remote control start time to the default time (12 hours later). To decide.
[0089]
On the other hand, when the current battery remaining ratio is smaller than the previous battery remaining ratio (S802: NO), the remote control server 4 further determines whether the current battery remaining ratio is smaller than 10%. I do. As a result of the determination, if the current battery remaining ratio is greater than 10% (S803: NO), the next remote control start time is set to a time later than the default time according to the weight value corresponding to the battery remaining ratio. To decide. That is, the time interval for remote control is set longer than the default (eg, weight 1 → 12 hours later, weight 0.5 → 18 hours later).
[0090]
On the other hand, if the current battery remaining ratio is smaller than 10% (S803: YES), the next remote control start time is determined to be the battery dead time at which the battery of the mobile phone 2 runs out. The estimated time of battery exhaustion is recorded in the remote control server 4 as statistical data in advance from the time when the remaining battery power of the mobile phone 2 falls below 10% until the power of the mobile phone 2 is turned off. Determine by referring to the data.
[0091]
As described above, according to the present embodiment, the remote control server 4 records the remaining battery ratio based on the remaining battery information obtained at the start of the remote control of the mobile phone 2 in the history information recording unit 46, The next remote control start time is determined based on the remaining battery ratio during remote control and the remaining battery ratio during current remote control.
[0092]
For this reason, when the remaining battery power of the mobile phone 2 is small, by increasing the interval of performing the remote control, the remote control itself of the mobile phone 2 does not consume the battery, and the standby time is extended. Can be achieved. In addition, when the battery level of the mobile phone 2 is extremely small, the user of the mobile phone 2 is required to perform remote control until the time when the battery level is finally depleted. In a situation where it is not desired to turn off the power of the mobile phone 2, it is possible to eliminate the possibility that the power is consumed by the remote control of the remote control server 4 and the power is turned off.
[0093]
(Fourth embodiment)
FIG. 9 is a configuration diagram of a remote control system according to the fourth embodiment of the present invention. The same components as those in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted.
As shown in FIG. 9, the remote control system 400 according to the fourth embodiment of the present invention relates to the operation of the mobile phone 2 in the configuration of the mobile phone 2 of the remote control system described in the first or second embodiment. An operation history information recording unit 28 for recording history information is added, and the remote control server 4 determines the next remote control start time according to the operation history information transmitted from the mobile phone 2.

[0096]
Next, a processing flow of the remote control system 400 according to the present embodiment will be described.
FIG. 10 is a sequence chart for explaining a processing flow of the remote control system according to the fourth embodiment of the present invention. The same sequences as those in FIG. 2 are denoted by the same reference numerals and description thereof will be omitted. FIG. 11 is a diagram showing the use tendency of the mobile phone analyzed by the remote control server of the remote control system according to the fourth embodiment of the present invention, in which the vertical axis represents the frequency of use and the horizontal axis represents time. is there.
[0097]
Upon receiving the trigger information, the mobile phone 2 acquires the battery remaining amount information, ID information, and operation history information of the own device at the time of receiving the trigger information (S1003), and acquires the acquired battery remaining amount information, ID information, and operation. The history information is transmitted to the remote control server 4 as a reply of the trigger information (S1004). After transmitting the control signal in S208, the remote control server 4 analyzes the usage tendency of the user of the mobile phone 2 on the mobile phone 2 based on the operation history information received from the mobile phone 2 (S1011). As a result of the analysis, the usage tendency of the mobile phone 2 is as shown in FIG. 11, and therefore, the remote control server 4 determines that the next remote control start time is the time zone (12 Hour to 24:00) is determined. As a result of the determination, if the next remote control start time is set between 12:00 and 24:00 (S1012: NO), the next remote control start time is changed from 0:00 to 12 when the user is not using the mobile phone 2. The time is determined to be one of the time periods up to the hour (S1013). On the other hand, when the next remote control start time is set between 0:00 and 12:00 (S1012: YES), the process proceeds to S201.
[0098]
As described above, according to the present embodiment, the usage tendency of the user of the mobile phone 2 is analyzed based on the operation history information of the mobile phone 2 acquired by the remote control server 4 when the remote control of the mobile phone 2 is started, and the analysis is performed. The next remote control start time is determined according to the result.
[0099]
For this reason, by setting any time in the time zone in which the user is not using the mobile phone 2 as the next remote control start time, the mobile phone 2 can be used in the time zone in which the battery of the mobile phone 2 is not much consumed. Can be remotely controlled. Therefore, the remote control can be performed while preventing the power of the mobile phone 2 from being turned off when the mobile phone 2 is frequently used. In addition, for the mobile phone 2, the standby time can be extended.
[0100]
(Fifth embodiment)

The gateway (GW) server connected to the telephone 2 is switched to another GW server according to the congestion state.
[0101]
FIG. 12 is a configuration diagram of a remote control system according to the fifth embodiment of the present invention. The same components as those in FIG. 1 are denoted by the same reference numerals and description thereof is omitted.
The remote control system according to the fifth embodiment of the present invention adds a connection monitoring unit 29 to the configuration of the mobile phone 2 shown in FIG. 1, and adds a server congestion status acquisition unit to the configuration of the control unit 42 of the remote control server 4. 424 is added, and a congestion status monitoring server 7 connectable to the network 3 is provided in the entire remote control system.
[0102]
When communicating with a certain web server, the communication unit 21 of the mobile phone 2 according to the present embodiment communicates with the web server via the GW server corresponding to the GW address recorded in the mobile phone setting data recording unit 25. I do.
[0103]
The connection destination monitoring unit 29 monitors the connection destination of the mobile phone 2 and acquires GW address information of the connected GW server. When the trigger information is received by the communication unit 21, the GW address information obtained here is obtained by the state information obtaining unit 24, and is transmitted to the remote control server 4 as the state information of the mobile phone 2 together with the remaining battery amount information.
[0104]
The congestion status monitoring server 7 monitors the congestion status of a web server connectable to the network 3 and the GW server that relays the web server, and records congestion status information indicating the congestion status in an internal memory or the like.
[0105]

The setting data of the unit 45 is updated. The remote control execution unit 423 generates a control signal for updating the gateway address of the connection destination of the mobile phone 2 based on the updated setting data of the mobile phone setting data recording unit 45, and transmits the control signal to the mobile phone 2. . This control signal may be transmitted simultaneously with a control signal for updating the execution time of the application program of the mobile phone 2, or may be transmitted separately.
[0107]
Next, a processing flow of the remote control system 500 according to the present embodiment will be described.
FIG. 13 is a sequence chart for explaining a processing flow of the remote control system according to the fourth embodiment of the present invention. The same sequences as those in FIG. 2 are denoted by the same reference numerals and description thereof will be omitted.
[0108]
Upon receiving the trigger information (S202), the mobile phone 2 acquires the battery remaining amount information of the own device and the GW address information of the connection destination at the time of receiving the trigger information (S1303), and obtains the acquired battery remaining amount information and the connection destination. Is transmitted to the remote control server 4 as a reply of the trigger information (S1304). After that, the remote control server 4 determines the control content based on the battery remaining amount information in S205, and then acquires the congestion status information of the GW server to which the mobile phone 2 is connected (S1312). When the remote control server 4 determines that the GW server to which the mobile phone 2 is connected is congested (S1313: YES), the remote control server 4 sends the address of the GW server to which the mobile phone 2 is connected via the GW server. Then, the GW address of the GW server that relays the mirror server of the connectable web server is determined (S1314), and the setting data of the mobile phone setting data recording unit 45 is updated (S206). Then, in S207, a control signal for updating the GW address is generated and transmitted to the mobile phone 2. The mobile phone 2 that has received the control signal switches the connection destination to the GW server corresponding to the GW address specified by the remote control server 4 (S1315).
[0109]
FIG. 14 is a diagram conceptually showing a process flow when changing the connection destination of the mobile phone in the remote control system according to the fifth embodiment of the present invention. As shown in FIG. 2, the GW servers 10 and 20 that relay the web server 40 and the GW server 30 that relays the web server 50 that is a mirror server of the web server 40 are connected to the network 3.
[0110]
As shown in FIG. 14, when the remote control server 4 transmits the trigger information to the mobile phone 2, the mobile phone 2 acquires the GW address information of the GW server 10 or 20 to which the mobile phone 2 is connected, and performs the remote control. Send it to server 4. The remote control server 4 acquires the congestion status information of the GW server corresponding to the received GW address information from the congestion status monitoring server 7. Here, since the GW servers 10 and 20 are busy, remote control is performed so that the connection destination of the mobile phone 2 is switched from the GW server 10 or 20 to the GW server 30. Thus, the mobile phone 2 switches the connection destination to the GW server 30 and connects to the web server 50.
[0111]
As described above, according to the present embodiment, the connection destination of the mobile phone 2 is switched based on the congestion status information of the GW server to which the mobile phone 2 is connected as the control content of the remote control server 4. For this reason, the mobile phone 2 can avoid connection to the crowded GW server or web server, and can browse the web without stress.
[0112]
When there are a plurality of mobile phones 2, the transmission timing of the trigger information of the remote control server 4 is not the timing determined by the trigger information control unit 421 described in the third or fourth embodiment, but the congestion status monitoring server. 7 may be received. By doing so, the connection destination of a plurality of mobile phones can be changed only when the server is congested, so that useless communication for the remote control server 4 can be reduced.
[0113]
When receiving the congestion status information from the congestion status monitoring server 7, the remote control server 4 does not transmit trigger information to all the mobile phones to be remotely controlled, but a mobile phone setting data recording unit. Based on the GW address information of each mobile phone recorded in 45 and the congestion status information received from the congestion status monitoring server 7, the GW address information of the GW server which is congested among a plurality of mobile phones is set. Alternatively, the trigger information may be transmitted only to the portable telephone set. By doing so, the trigger information is transmitted only to the mobile phone set to connect to the crowded GW server, so that unnecessary communication does not occur and the performance of the entire system is improved. Can be.
[0114]
In the present embodiment, control for changing GW address information set in the mobile phone 2 has been described as a specific example of remote control. However, in addition to control for changing GW address information, the connection destination of the mobile phone 2 may be changed. As the information, the remote control server 4 may control the change of the default URL or the emergency contact telephone number set in the mobile phone 2 in advance. For example, in an emergency such as a disaster, the user of the mobile phone 2 makes a call to a telephone number (emergency contact telephone number) registered in advance in the mobile phone 2 in preparation for an emergency, or accesses a default URL. This is effective when a situation in which information is acquired by assuming is performed.
[0115]
That is, in an emergency, it is expected that the base station or the server (GW server, web server) to which the mobile phone 2 is connected will be congested, but as in the present embodiment, the remote control server 4 By grasping the congestion status of the mobile phone 2 and remotely controlling the emergency contact number and the default URL set in the mobile phone 2 according to the congestion status, the user of the mobile phone 2 can use the most vacant base. Emergency communication and information collection via stations and servers are possible. This makes it possible to avoid the danger of being unable to contact anywhere in an emergency.
[0116]
(Sixth embodiment)
