PROBLEM TO BE SOLVED: To shorten time required for processing of logging call control messages in a mobile communication network and the like.SOLUTION: A data extraction device 100 comprises an acquisition unit 110, execution unit 120, and storage unit 140. The acquisition unit 110 acquires logs of mixed control messages of a plurality of calls. The execution unit 120 executes, in parallel, a plurality of pieces of extraction processing of extracting logs of control messages of extraction target calls differing from each other from the logs acquired by the acquisition unit 110. The storage unit 140 is a storage unit capable of being accessed in the plurality of pieces of extraction processing. 【課題】移動体通信網等において、呼制御メッセージのログ処理にかかる時間の短縮を図る。【解決手段】データ抽出装置１００は、取得部１１０と、実行部１２０と、記憶部１４０と、を備える。取得部１１０は、複数の呼の制御メッセージが混在するログを取得する。実行部１２０は、取得部１１０によって取得されたログの中からそれぞれ異なる抽出対象の呼の制御メッセージを抽出する複数の抽出処理を並列で実行する。記憶部１４０は、複数の抽出処理においてアクセス可能な記憶部である。【選択図】図１Ｂ
