Abstract

Dans ses modes de réalisation, la présente invention se rapporte à un procédé pour la transmission de données, qui est utilisé dans le but de réduire les coûts de transmission et les retards de services. Le procédé décrit dans les modes de réalisation de l'invention comprend les étapes suivantes : un dispositif de traitement de données multimédias reçoit une demande de service envoyée par un terminal d'utilisateur, le dispositif de traitement de données multimédias étant placé dans un réseau d'accès sans fil à l'intérieur duquel se trouve le terminal d'utilisateur ; le dispositif de traitement de données multimédias détermine s'il contient les données de service correspondant à la demande de service enregistrées en lui, ou non ; et, si les données de service sont enregistrées dans le dispositif de traitement de données multimédias, le dispositif de traitement de données multimédias envoie les données de service au terminal d'utilisateur. Les modes de réalisation de l'invention décrivent par ailleurs un appareil et un système pour la transmission de données. Les modes de réalisation de l'invention sont aptes à réduire effectivement les coûts de transmission et les retards de service.
