(EN) A method of establishing a Voice over Internet Protocol, VoI P, call between a calling User Equipment, UE, and a called UE, wherein said calling UE is served by a core network via a packet-switched radio access network, PS-RAN, and wherein a bearer is to be established between said calling U E and a gateway node in said core network, over said PS-RAN, for obtaining access to an Internet Protocol, IP, multimedia subsystem, I MS, network, wherein said method comprises the steps receiving, by a an IMS Call Session Control Function, CSCF, node a notification message thereby notifying said I MS node that said VoIP call establishment is in progress and initiating, by said I MS CSCF, re-establishment of said bearer between said calling UE and said gateway node, over said PS-RAN, in case said establishment of said bearer has failed due to a temporary failure.
(FR) L'invention concerne un procédé d'établissement d'un appel vocal sur protocole Internet (VoIP) entre un équipement utilisateur (UE) appelant et un UE appelé, ledit UE appelant étant desservi par un réseau central par l'intermédiaire d'un réseau d'accès radio à commutation par paquets (PS-RAN), un support devant être établi entre ledit UE appelant et un nœud de transit dans ledit réseau central, sur ledit PS-RAN, pour obtenir un accès à un réseau de sous-système multimédia de protocole Internet (IMS), ledit procédé comprenant les étapes consistant à recevoir, par un nœud de fonction de commande de session d'appel (CSCF) IMS un message de notification notifiant audit nœud IMS que ledit établissement d'appel VoIP est en cours et à initier, par ladite CSCF IMS, le rétablissement dudit support entre ledit UE appelant et ledit nœud de transit, sur ledit PS-RAN, dans le cas où ledit établissement dudit support a échoué en raison d'une défaillance temporaire.
