摘要： The invention relates to a method for performing a handover of a mobile node (MN) from a source to a target network, wherein a handover proxy node (HPN) is used to relay the handover of the MN to one of previously measured cells. The MN discovers an appropriate HPN and triggers the handover to the HPN by reporting the measurements together with the HPN ID as destination of the handover. When receiving the Handover Initiation message for handing over the MN to the HPN, the HPN will not proceed with the handover but adapts said handover to indicate a handover of the MN from the HPN to the target base station. Upon receiving the Handover Initiation message in the target network, system resources are configured for data forwarding between the source and target network, and for the data path used by the MN when attaching to the target base station.

摘要： Disclosed is a technique to enable a communication node to acquire predetermined newer information (e.g., configuration information) held by another communication node while minimizing power consumption by communication nodes. According to the technique, when receiving a request for configuration information from a new MTC device 100, a MME 220 checks whether an existing MTC device 110 as a request target for configuration information connects or not. When the existing MTC device does not connect, the new MTC device is notified of time information (e.g., next connection time of the existing MTC device, a next connection time of a new MTC device or a next connection time zone of the new MTC device). This time information enables the new MTC device to specify a time after the MME acquires and holds the configuration information from the existing MTC device. The new MTC device reconnects based on this time information, whereby the new MTC device can acquire desired configuration information from the MME.

摘要： The invention provides a method for trust relationship detection between a core and access network for a user equipment. The gist is that a security tunnel establishment procedure is used so one entity, be it part of the core network or be it the user equipment itself, is provided with information to determine whether the access network is trusted or untrusted. The information may comprise a first IP address/prefix, which is initially assigned to the user equipment, upon attaching to the access network. The necessary information may further comprise a second IP address/prefix, which is an address/prefix that is allocated at a trusted entity of the core network. Depending which entity determines the trust relationship of the access network, it might be necessary to transmit either the first IP address/prefix or the second IP address/prefix or the first and the second IP address/prefix using the security tunnel establishment procedure.

The method comprises the steps of providing an estimation whether the user equipment is unknown at the mobility management entity and sending the user equipment's temporary identity during the network attachment procedure. If the user equipment has been estimated to be unknown at the at least one mobility management entity, the user equipment's identity is sent during the network attachment procedure. These steps are carried out by the user equipment.

摘要： Disclosed is a technique to enable a user equipment at a remote place to perform local IP access to a locally-accessible network with simpler procedure and such a configuration while achieving the efficiency of costs and facility. According to the technique, a network (LIA-PDN 161) capable of dealing with a local IP access by a user equipment (UE 101) is placed on a core network 141. When the UE establishes a PDN connection with the LIA-PDN, the UE simultaneously transmits information concerning the LIA domain network 111 as well, to which the UE wants a local IP access. On the basis of this information, the LIA-PDN establishes a PDN connection with the LIA domain network, and the LIA-PDN transfers a packet, whereby the UE can access the LIA domain network via these PDN connections.

摘要： The invention relates to a method for ensuring IP session continuity upon a handover of a mobile node to a non-3GPP network, wherein an ongoing IP session of the mobile node goes via a packet data network gateway. For non-3GPP networks it is necessary to discover a security gateway and to then establish the corresponding tunnels to the ePDG to form the new data path; a security tunnel between the mobile node and the security gateway, and an IP tunnel between the packet data network gateway and the security gateway. In order to prepare the handover to possible non-3GPP accesses, the two tunnels are pre-established, however maintained deactivated until their use is actually needed. Accordingly, when handing over to the non-3GPP network, the IP session may be continued without any significant interruption by activating the already established tunnels.
