Title
(EN) CHANGING LTE SPECIFIC ANCHOR WITH SIMPLE TUNNEL SWITCHING
(FR) MODIFICATION D'UNE ANCRE LTE SPÉCIFIQUE PAR UNE COMMUTATION SIMPLE DE TUNNEL
Abstract
(EN)
Embodiments of the invention may further provide a method for transferring an LTE anchor in an idle mode. The method includes an MME (control plane entity) initiating an LTE anchor change procedure, the MME first commands the selected new LTE anchor to set up a user plane tunnel towards the 3GPP anchor and then it updates this information towards the 3GPP anchor. Thereafter, the old tunnel is deleted from the old LTE anchor.
(FR)
Certains modes de réalisation de l'invention servent en outre à mettre en œuvre un procédé destiné à placer une ancre LTE dans un mode d'inactivité. Le procédé comporte le déclenchement par une entité MME (entité de plan de commande) d'une procédure de modification d'ancre LTE, l'entité MME commandant initialement la nouvelle ancre LTE sélectionnée pour configurer un tunnel de plan utilisateur auprès de l'ancre 3GPP, puis actualisant ces informations auprès de l'ancre 3GPP. L'ancien tunnel est ensuite supprimé de l'ancienne ancre LTE.
