Abstract

【課題】非接触通信デバイスが接続される情報処理装置が省電力モードに設定されていても、当該非接触通信デバイスと他の非接触通信デバイスとの間で通信可能な情報処理技術を提供する。 【解決手段】NFCデバイスND1は、情報処理装置50に対するデータの読み出しやデータの書き込みの要求を通信端末PC1から受信すると、省電力状態の情報処理装置50に起動を要求する。電力投入制御部502は、情報処理装置50が省電力状態である場合、NFCデバイスND1からの要求に応じて、情報処理装置50を起動させる。NFC制御部503は、情報処理装置50が省電力状態である場合、NFCデバイスND1の通信モードをパッシブタブモードに切り替え、NFCデバイスND1を介してデータの読み出しやデータの書き込みの要求があった場合、NFCデバイスND1の通信方式をP2P通信に切り替える。 【選択図】図1
<P>PROBLEM TO BE SOLVED: To provide an information processing technology which allows communication between a noncontact communication device and another noncontact communication device possible even if an information processing device, to which the former noncontact communication device is connected, is set to a power-saving mode. <P>SOLUTION: When an NFC (Near Field Communication) device ND1 receives a request for reading data from or writing data to an information processing device 50 from a communication terminal PC1, it requests the information processing device 50 in a power-saving mode to start up. A power application-controlling part 502 makes the information processing device 50 start up in compliance with the request from the NFC device ND1 in case that the information processing device 50 is in a power-saving mode. An NFC-controlling part 503 changes the communication mode of the NFC device ND1 to a passive tab mode when the information processing device 50 is in a power-saving mode, and changes a communication method used by the NFC device ND1 to a P2P (Peer to Peer) communication method when a request for reading data or writing data is made through the NFC device ND1. <P>COPYRIGHT: (C)2011,JPO&INPIT
