Abstract:
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.
