A method for quality of ser-vice (QoS) parameters mapping during a handover from a first radio access network (RAN) (source RAN, 104) to a second RAN (target RAN, 106), the first RAN hav-ing communication with at least one access point name (APN), comprising: deriving an APN aggregated maximum bit rate (APN--AMBR) based on a maximumbit rate (MBR) of a packet data protocol (PDP) context associated with a first APN of the first RAN (104); providing a local user equipment (UE) agrregated maximum bit rate (UE-AMBR) until a subscribed UE--AMBR is available for the UE,- acquiring the subscribed UE-AMBR,- calculating a derived UE-AMBR by taking the miumi-mum of the subscribed UE-AMBR and the sum of all APN-AMBRs of all active APNs associated with the UR; comparing the der-vided UE-AMBR to the local UE-AMBR; and initialing a subscribed quality of ser-vice (QoS) modification procedure to notify the derived UE-AMBR if the local UE--AMBR is different from the dervied UE--AMBR.

L'invention concerne un procédé pour une mise en correspondance de paramètres de qualité de service (QoS) pendant un transfert depuis un premier réseau d'accès radio (RAN) (RAN source, 104) vers un second RAN (RAN cible, 106), le premier RAN étant en communication avec au moins un nom de point d'accès (APN), consistant : à obtenir un débit binaire maximum total d'APN (APN-AMBR) sur la base d'un débit binaire maximum (MBR) d'un contexte de protocole de données par paquet (PDP) associé à un premier APN du premier RAN (104) ; à fournir un débit binaire maximum (UE-AMBR) total d'équipement d'utilisateur local (UE) jusqu'à ce qu'un UE-AMBR abonné soit disponible pour l'UE, acquérant l'UE-AMBR abonné, calculant un UE-AMBR obtenu en prenant le minimum de l'UE-AMBR abonné et la somme de tous les APN-AMBR de tous les APN actifs associés à l'UR ; à comparer l'UE-AMBR obtenu avec l'UE-AMBR local, et à initialiser une procédure de modification de qualité de service (QoS) abonnée pour informer l'UE-AMBR obtenu si l'UE-AMBR local est différent de l'UE-AMBR obtenu.
