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.

摘要： The invention relates to a method for discovering a home agent serving a mobile node upon the mobile node changing its mobility management scheme in a packet-switched network and the implementation of such method in a mobile node or home agent. In order to propose a home agent discover scheme that maintains session continuity in a seamless manner upon a mobile node changing its mobility management scheme, a mobile node comprises information on its location prior to changing the mobility management scheme to one of the first signaling messages transmitted upon changing the mobility management scheme (home agent discovery message). The receiving node uses this information to identify the home agent serving the mobile node or to provide a hint to the home agent where the mobile node is registered in a response message to the mobile node. This approach may also be used for path optimization when a mobile node moves from a trusted to an un-trusted access network.

摘要： The present invention relates to a method and computer-readable medium for loop detection in data packet communication utilizing a tunnel in a network comprising a plurality of nodes. The method comprises the steps of, when a first node transmits a data packet, encoding an identification of the first node in at least two header fields of the data packet to be transmitted, and when the first node receives a data packet, analyzing the at least two header fields of the data packet, deciding if a loop exists by determining if the data packet was sent by the first node itself, based on the analysis of the at least two header fields of the data packet.

摘要： The invention relates to a method for a handover of a mobile node from a non-3GPP to a 3GPP network, and of a mobile node, which is located in a non-3GPP/3GPP network. The handover is improved by discovering an appropriate MME and registering the mobile node at the discovered MME, in advance. This includes to first determine the location of the mobile node in the non-3GPP network, so as to be able to detect an MME in the vicinity of the mobile node's location. The 3GPP contexts are then transmitted to the new MME before the handover is performed. Moreover, the invention teaches to change the Serving-Gateway in the 3GPP network before performing a handover, thereby accelerating the handover. When a handover gets likely, the mobile node's location is determined and a new Serving-Gateway is selected. The data path is changed to go via the new Serving-Gateway.

摘要： The invention relates to a method for routing packets in a system of packet-switched networks using different internet protocol versions. The system comprises a plurality of home agents, at least one mobile node and at least one correspondent node. A first mobile node is configured with at least one topologically correct internet protocol address of a first internet protocol version and is located in a network supporting at least routing of packets having a header of the first internet protocol version. The method comprises the following steps. Communication is requested with a first correspondent node being configured with at least an internet protocol address of a second internet protocol version and being located in a network supporting at least the routing of packets having a header of the second internet protocol version, by an application on the first mobile node. A first of the plurality of home agents is located in proximity to a direct path between the first mobile node and the first correspondent node, the first home agent being located in a network supporting at least the routing of packets to the first mobile node with the packets having a header of the first internet protocol version and the routing of packets to the first correspondent node with the packets having a header of the second internet protocol version. Bootstrapping is carried out with the first home agent to obtain a first home address of the second internet protocol version and other communication parameters. The first mobile node's location is registered with the first home agent by sending a first binding update message comprising a first mobile node's topologically correct address of the first internet protocol version as care-of address and the first home address as home address; and the first home agent is used in bi-directional tunnelling mode, the outer header of the tunnelled packets using the first internet protocol version and the inner header of the tunnelled packets using the second internet protocol version, for communication with the first correspondent node, with the communication parameters set up in the bootstrapping step and the first home address as home address.
