摘要： The invention relates to a method for tracking locations of mobile terminals in a communication network. Further, the invention relates to a communication network and apparatuses therein capable of performing individual steps of the method according to different embodiments of the invention. To decrease the signaling load imposed by mobility related signaling the invention suggests to group mobile terminals in so called mobility groups and to reduce the signaling overhead by performing a location update on a per-mobility group basis. In one exemplary embodiment of the invention this is realized by only one of the mobile terminals in a mobility group sending a group location update on behalf of the group to trigger the location update for the mobility group. Alternatively, in another embodiment of the invention, a network operator trusted or controlled entity sends a group location update on behalf of the group to trigger the location update for the mobility group.

摘要： The invention relates to a method for managing the movement of a mobile node from a first router in a first network to a second router in a second network, wherein the mobile node communicates with a corresponding node. In order to enable seamless communication between the mobile node and the corresponding node, the second router is dynamically configured by the first router to transmit a router advertisement message to the mobile node, the router advertisement message comprising a subnet prefix of an IP address of the mobile node, said subnet prefix belonging to the first network. A layer 3 link change as observed by the mobile node can be postponed and a default router of the mobile node can be changed to the new access router immediately after the layer 2 handover, thus enabling very fast handovers without requiring modifications to the mobile node implementations.

摘要： The invention relates to a method and mobile node capable of detecting whether or not the network to which the mobile node is attached is using a network-based mobility management function for the mobile node or not. In order to enable a mobile node to detect whether the network is using a network-based mobility function for the mobile node, upon establishment of a PDN connection or IP session, the mobile node sends a probe message to the network destined to itself and determines based on the modifications of the probe message returned to the mobile node whether the network is using a network-based mobility function for the mobile node or not.

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： A method and a server acting as a Home Agent are provided for packet switched data transmission between a first mobile node and a correspondent mobile node in a mobile communication system comprising a plurality of mobile networks. Each of the first mobile node and the correspondent mobile node are allocated to respective home networks, and a network server is provided as a home agent to each mobile node, respectively. Then, data packets are routed from the first mobile node to the correspondent mobile node, over a first data tunnel from the first mobile node to any first one of the home agents and over a second data tunnel from said first one of the home agents to the correspondent mobile node without passing the respective other home agent.

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 performed by a home agent serving a mobile node in a home network of the mobile node upon attachment of a mobile node to the home network as well as to the home agent. Further, the invention also relates to a method for enabling simultaneous use of a plurality of interfaces by a mobile node being attached to a home network through one of the plurality of interfaces and to at least one foreign network through at least another interface of the plurality of interfaces. Moreover, the invention provides a mobile node and a proxy acting on behalf of the mobile node. To enable a mobile node to use a home network and at least one further foreign network for communications the invention suggests the registration of the mobile node's home address or of a network node within its home network as a care-of address in the home network.
