Title
(EN) CONTROLLING FALLBACK PROCEDURES FOR DIFFERENT USER GROUPS OR DEVICE GROUPS
(FR) COMMANDE DE PROCÉDURES DE REPLI POUR DIFFÉRENTS GROUPES D'UTILISATEURS OU GROUPES DE DISPOSITIFS
Abstract
(EN)
A user equipment (UE) and an Internet Protocol (IP) Multimedia Subsystem (IMS) node may exchange fallback indicators in SIP signaling for purposes of controlling fallback procedures implemented by the UE. The SIP signaling may include a SIP request from the UE that includes first information. The IMS node can evaluate a criterion based on the first information, and, if the criterion is met, the IMS node may authorize (or prohibit) the use of a UE-supported fallback radio access technology (RAT) that corresponds to a fallback indicator also included in the SIP request. Based on the evaluation of the criterion, the IMS node may respond to the UE with a SIP response that includes second information indicating which of the supported Fallback RATs the UE is authorized to use (if any), and which of the supported Fallback RATs the UE is not authorized to use (if any).
(FR)
Un équipement utilisateur (UE) et un nœud de sous-système multimédia (IMS) à protocole Internet (IP) peuvent échanger des indicateurs de repli dans une signalisation SIP à des fins de commande de procédures de repli mises en œuvre par l'UE. La signalisation SIP peut comprendre une demande SIP de l'UE, qui comprend des premières informations. Le noeud IMS Peut évaluer un critère sur la base des premières informations, et, si le critère est satisfait, le noeud IMS peut autoriser (ou interdire) l'utilisation d'une technologie d'accès radio (RAT) de repli prise en charge par un UE, qui correspond à un indicateur de repli également inclus dans la demande SIP. En fonction de l'évaluation du critère, le nœud IMS peut répondre à l'UE par une réponse SIP qui comprend des deuxièmes informations indiquant quelle technologie parmi les RAT de repli prises en charge l'UE est autorisé à utiliser (s'il en existe), et celle des RAT de repli prises en charge que l'UE n'est pas autorisé à utiliser (s'il en existe).
