Abstract

L'invention concerne un procédé et un dispositif de gestion d'informations de contexte dans un réseau hétérogène. Le procédé de la présente invention met en jeu : un dispositif de station de base qui obtient des informations de contexte relatives à un équipement utilisateur dans un réseau non-3GPP et le dispositif de station de base gérant les informations de contexte relatives à l'équipement utilisateur dans le réseau non-3GPP. Dans les modes de réalisation de la présente invention, quand l'équipement utilisateur est commuté d'un réseau 3GPP au réseau non 3GPP, le dispositif de station de base peut gérer les informations de contexte relatives à l'équipement utilisateur dans le réseau non-3GPP de manière à ce que le dispositif de station de base puisse utiliser les informations de contexte relatives à l'équipement utilisateur dans le réseau non-3GPP pour réaliser un traitement pertinent. Le dispositif de station de base utilise donc les informations de contexte relatives à l'équipement utilisateur dans le réseau non-3GPP pour déterminer s'il faut réaliser une configuration de mesure et/ou utilise les informations de contexte relatives à l'équipement utilisateur dans le réseau non-3GPP pour déterminer s'il faut réaliser une commutation de service, etc.
