The present invention has the purpose of providing technology capable of efficiently transmitting data when performing data communications between a mobile station and a server apparatus. A simplified protocol TL is employed on the transport layer instead of TCP/IP. The simplified protocol TL is used as the communication protocol on a wireless communication path (radio-oriented interval) between an MS (Mobile Station) 1 and a GWS (GateWay Server) 5. The simplified TL protocol is utilized to relay data communications between the MS 1 and a CPS 8 (Content Provider Server). The response of data communications is therefore improved by a decrease in traffic between the MS 1 and the GWS 5 and reduction in overhead in comparison to when TCP/IP is deployed. As a result, the user can efficiently access content provided by the CPS 8 over the Internet via a wireless communication path. Efficient access may occur even where the wireless communication path has low data transmission capacity in comparison to a wireline communication path. In addition, efficient access may occur where the user is using an MS 1 which has insufficient data processing power to deploy TCP/IP.
L'invention concerne une technique permettant de transmettre efficacement des données lors d'une communication de données entre une station mobile et un dispositif serveur. De la même façon qu'un protocole de communication est utilisé dans une section liaison radioélectrique entre un serveur GWS (GateWay Server) (5) et une station mobile (MS) (1), afin de relayer une communication de données entre ladite station MS (1) et un serveur CPS (Contents Provider Server) (8), on met en oeuvre le protocole TL, qui est un protocole simplifié, dans des couches de transport, et ce au lieu d'appliquer le protocole TCP/IP. On fait ainsi diminuer le trafic entre la station MS (1) et le serveur GWS (5), ainsi que toute surcharge, tout en améliorant la réponse de communication de données, et ce plus efficacement qu'avec un protocole TCP/IP. Le contenu fourni par le serveur CPS (8) sur Internet peut donc être facilement utilisé par l'intermédiaire de la section liaison radioélectrique, qui présente une faible capacité de transfert de données.
