Abstract: front page image
(EN)The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for performing WLAN-based P2P communication at the state where a P2P apparatus is connected to a cellular network and to a first P2P apparatus for the method. The method comprises: a step of receiving one or more pieces of key information from a cellular base station, each piece of key information including a key value corresponding to service identification information; a step of receiving an encrypted data signal from a second P2P apparatus; and a step of performing a process of attempting to decrypt said encrypted data signal using one or more keys corresponding to one or more services in which said first P2P apparatus is interested, from among said one or more pieces of key information.
(FR)La présente invention se rapporte à un système de communication sans fil. De manière plus spécifique, l'invention concerne un procédé pour réaliser une communication P2P fondée sur un WLAN lorsqu'un appareil P2P est connecté à un réseau cellulaire, ainsi qu'un premier appareil P2P servant à la mise en œuvre dudit procédé. Le procédé selon l'invention comprend les étapes qui consistent : à recevoir une ou plusieurs informations de clé provenant d'une station de base cellulaire, chaque information de clé comportant une valeur de clé qui correspond à une information d'identification de service ; à recevoir un signal de codé chiffré provenant d'un deuxième appareil P2P ; et à exécuter une tentative de déchiffrement pour déchiffrer ledit signal de données chiffré au moyen d'une ou de plusieurs clés correspondant à un ou plusieurs services auquel/auxquels le premier appareil P2P s'intéresse, parmi lesdites informations de clé.
(KO)본 발명은 무선 통신 시스템에 관한 것이다. 구체적으로, 본 발명은 셀룰러 네트워크에 연결된 상태에서 WLAN-기반 P2P 통신을 수행하는 방법 및 이를 위한 제1 P2P 장치에 있어서, 셀룰러 기지국으로부터 하나 이상의 키 정보를 수신하되, 각각의 키 정보는 서비스 식별 정보와 대응하는 키 값을 포함하는 단계; 제2 P2P 장치로부터 암호화된 데이터 신호를 수신하는 단계; 상기 하나 이상의 키 정보 중, 상기 제1 P2P 장치가 관심 있는 하나 이상의 서비스에 대응하는 하나 이상의 키를 이용하여 상기 암호화된 데이터 신호의 해독화를 시도하는 위한 과정을 수행하는 단계를 포함하는 방법 및 이를 위한 장치에 관한 것이다.
