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.

Abstract: A method comprising: switching a mobile user equipment from a detached state to an active state; and transferring at least part of user profile information from an old control node, to which the mobile user equipment was formerly attached, to a new control node, to which the mobile user equipment is attached.

Abstract: Measures for a handover in a communication system, the communication system comprising an access network having at least two base station entities and a core network having at least two control plane entities and at least one user plane entity, comprising the steps of initiating, upon completion of a radio network handover between a source base station entity and a target base station entity, a core network handover by the target base station entity, and performing the core network handover between a source control plane entity and a target control plane entity, wherein the user plane entity is maintained the same or changed.

Abstract: The present invention relates to a method, terminal device, network element, authentication server, and computer-readable medium for controlling prioritized access to a wireless access network. An identifier portion in an authentication response is set to a service-specific unique default identifier portion, dedicated to a predetermined prioritized call, at a terminal device, when the predetermined prioritized call is activated. The authentication response is forwarded to a predetermined default authentication server where a predetermined default service-specific authentication method is initiated for authorizing the terminal device to access the predetermined prioritized service. Thereby, emergency calls or services are made by terminal devices without SIM or USIM, and no new authentication functionality related to prioritized calls is required due to the transparent character of the service-specific unique default identifier portion.
