Abstract: front page image
(EN)The present invention relates to a method and an apparatus for switching a data path in a wireless communication system supporting device-to-device (D2D) communication. The method for switching a path of a base station in a wireless communication system supporting device-to-device communication, according to the present invention, comprises the steps of: receiving, from a first terminal, a measurement report including a D2D identifier of a second terminal that performs a direct communication with the first terminal; sending a query to a D2D server for a network identifier corresponding to the D2D identifier of the second terminal; and determining whether to switch a direct path between the first terminal and the second terminal to a local path on the basis of the network identifier of the second terminal obtained from the D2D server.
(FR)La présente invention porte sur un procédé et un appareil de commutation de chemin de données dans un système de communication sans fil prenant en charge une communication de dispositif à dispositif (D2D). Le procédé de commutation de chemin d'une station de base dans un système de communication sans fil prenant en charge une communication de dispositif à dispositif, selon la présente invention, consiste : à recevoir, en provenance d'un premier terminal, un rapport de mesure comprenant un identifiant D2D (D2D ID) d'un second terminal qui effectue une communication directe avec le premier terminal ; à envoyer à un serveur D2D une interrogation demandant un identifiant réseau correspondant à l'identifiant D2D du second terminal ; et à déterminer l'opportunité de faire commuter un chemin direct entre le premier terminal et le second terminal vers un chemin local sur la base de l'identifiant réseau du second terminal obtenu auprès du serveur D2D.
(KO)본 발명은 단말 간 직접(DEVICE TO DEVICE, D2D) 통신을 지원하는 무선 통신 시스템에서 데이터 경로 전환 방법 및 장치에 관한 것으로, 본 발명의 단말 간 직접통신을 지원하는 무선 통신 시스템에서 기지국의 경로 전환 방법은 제1 단말로부터, 상기 제1 단말과 직접 통신을 수행하는 제2 단말의 D2D 식별자를 포함하는 측정 보고를 수신하는 단계, 상기 제2 단말의 D2D 식별자에 대응하는 네트워크 식별자를 D2D 서버에 문의하는 단계, 상기 D2D 서버로부터 획득한 상기 제2 단말의 네트워크 식별자에 기반하여 상기 제1 단말 및 제2 단말 사이의 직접 경로를 로컬 경로로 전환할 것인지 결정하는 단계를 포함하는 것을 특징으로 한다.
