Abstract

L'invention concerne un procédé d'acquisition d'informations d'accès d'un terminal utilisateur. Ce procédé consiste principalement à : déterminer si le type de réseau d'accès du terminal utilisateur est connu (201); acquérir les informations d'accès du terminal utilisateur en fonction de la détermination (202), c'est-à-dire, si ce type de réseau est connu, acquérir les informations d'accès du terminal utilisateur depuis le réseau d'accès correspondant à ce type de réseau d'accès; s'il est inconnu, acquérir les informations de ce type de réseau d'accès du terminal utilisateur et acquérir les informations d'accès du terminal utilisateur provenant du réseau d'accès correspondant à ce type de réseau d'accès. L'invention concerne également un appareil et un système permettant d'acquérir des informations d'accès d'un terminal utilisateur sur la base du procédé précité. Les modes de mise en oeuvre de cette invention comprennent l'acquisition des informations d'accès du terminal utilisateur depuis le type de réseau d'accès du terminal utilisateur, mais non l'acquisition des informations d'accès dans le cas d'un type de réseau d'accès implicite du terminal utilisateur, ce qui permet de s'assurer efficacement que l'acquisition portera sur les informations d'accès exactes du terminal utilisateur.
