Abstract

Des modes de réalisation de la présente invention concernent un procédé et un appareil de transmission de données de service. Un dispositif terminal comprend : une unité de détermination pour déterminer un support de données radio portant de premières données de service entre l'unité de détermination et une station de base; et une première unité d'envoi pour envoyer les premières données de service à la station de base via le support de données radio, les premières données de service étant transmises à un premier serveur de services par le dispositif terminal. La station de base envoie ainsi les premières données de service au premier serveur de services via une connexion TCP correspondant aux premières données de service, la connexion TCP correspondant aux premières données de service étant une connexion TCP entre la station de base et le premier serveur de services. Comme une station de base peut envoyer séparément des éléments de données de service à des serveurs de services via des connexions TCP correspondantes, une communication entre un dispositif terminal et une pluralité de serveurs de services est implémentée et, comme les connexions TCP ne sont pas établies directement entre le dispositif terminal et les serveurs de service, les ressources du réseau radio peuvent ainsi être économisées.
