Title (EN) WIRELESS COMMUNICATION SYSTEM AND METHOD FOR TRANSMITTING CONTENT IN WIRELESS COMMUNICATION SYSTEM
(FR) SYSTÈME ET PROCÉDÉ DE COMMUNICATION SANS FIL POUR TRANSMETTRE UN CONTENU DANS UN SYSTÈME DE COMMUNICATION SANS FIL
(KO) 무선 통신 시스템 및 그 무선 통신 시스템에서 컨텐츠 전송 방법
Abstract: front page image
(EN)The present invention relates to a wireless communication system and a method for managing a cache server in the wireless communication system, the invention includes a step for checking a regional cache server to transmit contents when a DNS(Domain Name System) request a message for receiving contents acquired from a terminal, and a step for transmitting the contents by the cache server according to a contents request message received from the terminal. These steps can prevent the same data from being transmitted several times through a wireless communication network. Therefore, network usage associated with the service is reduced, and the network can be used more efficiently.
(FR)La présente invention concerne un système de communication sans fil et un procédé pour gérer un serveur de mémoire cache dans le système de communication sans fil. L'invention comprend une étape pour vérifier un serveur de mémoire cache régionale pour transmettre des contenus lorsqu'un DNS (système de nom de domaine) demande un message pour recevoir des contenus acquis à un terminal, et une étape pour transmettre les contenus par le serveur de mémoire cache conformément au message de demande de contenus reçu du terminal. Ces étapes permettent d'éviter que les mêmes données soient transmises plusieurs fois à travers un réseau de communication sans fil. Par conséquent, l'utilisation du réseau associée au service est réduite, et le réseau peut être utilisé plus efficacement.
(KO)본 발명은 무선 통신 시스템 및 그 무선 통신 시스템에서 캐시 서버를 관리하는 방법에 관한 것으로, 단말로부터 컨텐츠 수신을 위한DNS(Domain Name System) 요청 메시지가 획득되면, 상기 컨텐츠를 전송하기 위한 지역 캐시 서버를 확인하는 과정과, 상기 지역 캐시 서버는 상기 단말로부터 수신되는 컨텐츠 요청 메시지에 따라 컨텐츠를 전송하는 과정을 포함한다. 이러한 과정들을 통해 동일한 데이터가 무선 통신 네트워크를 통해 여러 번 전송되는 것을 방지할 수 있다. 이에 따라 서비스에 대한 네트워크 사용량이 줄어들며, 네트워크를 보다 효율적으로 사용할 수 있다.
