Abstract
(EN)
A wireless device (120) and method for re-establishing a radio connection in a communications network (100) comprising a first RAT and a different second RAT. The wireless device is operating in a first cell (11) served by a first radio network node (110) operating in the first RAT. When a connection failure with the first cell is detected, the 5wireless device performs a cell selection and selects a second cell (12) served by a second radio network node (112) operating in the second RAT. The second cell is known by the wireless device to be a candidate for re-establishment. The wireless device determines a first set of parameters to be used as an identifier of the wireless device, wherein the first set of parameters is associated with the first cell. The wireless device 10transmits, to the second cell, a re-establishment request message comprising the first set of parameters.
(FR)
La présente invention concerne un dispositif sans fil (120) et un procédé de rétablissement d'une connexion radio dans un réseau de communication (100) comprenant une première RAT et une seconde RAT différente. Le dispositif sans fil fonctionne dans une première cellule (11) desservie par un premier nœud de réseau radio (110) fonctionnant dans la première RAT. Lorsqu'une défaillance de connexion avec la première cellule est détectée, le dispositif sans fil réalise une sélection de cellule et sélectionne une seconde cellule (12) desservie par un second nœud de réseau radio (112) fonctionnant dans la seconde RAT. La seconde cellule est connue par le dispositif sans fil pour être un candidat pour un rétablissement. Le dispositif sans fil détermine un premier ensemble de paramètres à utiliser en tant qu'identifiant du dispositif sans fil, le premier ensemble de paramètres étant associé à la première cellule. Le dispositif sans fil transmet, à la seconde cellule, un message de demande de rétablissement comprenant le premier ensemble de paramètres.
