Abstract  Abstract

A user equipment device (100), UE, comprising: a processing circuitry and a radio transceiver for both cellular access and WLAN wireless local area network, where the processing circuitry is adapted for: when acquired network access of a visited cellular operator and one or more WLAN, wireless local area network, retrieve a configuration that indicates a preference or not for the preservation of the IP address (internet protocol), when switching between cellular access and WLAN; if no preference is indicated for the preservation of the IP address, prefer the selection and network routing guidelines as indicated by the information of the ANDSF, detection function and access network selection, received from a server of the H -ANDSF (165), ANDSF of the local operator, against the information received from a V-ANDSF server (125), ANDSF of the visited operator; characterized in that this circuitry is further adapted to: if a preference is indicated for the preservation of the IP address, prefer network selection and routing guidelines as indicated by the V-ANDSF server over those indicated by the server. H-ANDSF, only if the V-ANDSF server indicates that the visited operator has support for WLAN access using an S2a interface.
