摘要： In node management in a packet-switched network, a first node acts as a proxy for a second node. Both nodes have network-layer addresses at the network layer and link-layer addresses at the link layer. The first node receives a request to receive and forward packets addressed to the second node's network-layer address. The same network-layer address is associated with the first and the second node, and the first and the second node have distinct link-layer addresses. The first node advertises to nodes attached to the packet-switched network the first node's link-layer address as a destination address for the second node's network-layer address; the second node does not advertise. The first node receives in response to advertising, packets destined to the second node's network-layer address having the first node's link-layer address and forwards packets addressed to the second node's network-layer address to the second node using its link-layer address.

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 methods for (re)attaching a UE to a 3GPP access network and for storing bearer context information of a UE upon handover from a 3GPP access network to a non-3GPP access network. Furthermore, the invention relates to 3GPP network nodes, such as mobility management entity, serving gateway and packed data gateway, and a UE that are specially adapted to perform these methods. In order to decrease of the delay time during (re)attachment of a UE to a 3GPP access network, the invention proposes to maintain context information on data bearer(s) of a UE within the 3GPP access network and the UE, while the UE is not attached to the 3GPP access network, so that data bearer context information for this UE is available and can be used for the (re)activation of data bearer(s) once the UE is attaching to the 3GPP access network again.

摘要： The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.

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 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.

摘要： A method and apparatus for improved context transfer in heterogeneous networks is presented. Context information is collected from source entities in a first access network by a context transfer manager and transmitted to a context transfer manager of a second access network which forwards the context information to target entities therein. In one of the context transfer managers at least a part of the context information is translated from a format supported in the first access network to another format supported in the second access network. The method may be carried out proactively preceding a handover or reactively following a handover. In one embodiment, context transfer within one access domain is performed directly between access routers, whereas context transfer between different access domains is performed via the context managers. In another embodiment, beacons from access points are counted in order to determine candidates for a pending handover.
摘要翻译：提出了一种用于改进异构网络中的上下文传输的方法和装置。上下文信息由上下文传送管理器从第一接入网络中的源实体收集，并被发送到第二接入网络的上下文传送管理器，该第二接入网络将该上下文信息转发给其中的目标实体。在上下文传送管理器之一中，将上下文信息的至少一部分从第一接入网络中支持的格式转换为第二接入网络中支持的另一格式。该方法可以主动地在切换之前或反应地跟随切换之后执行。在一个实施例中，一个接入域内的上下文传送在接入路由器之间直接执行，而不同接入域之间的上下文传送是经由上下文管理器执行的。在另一个实施例中，对来自接入点的信标进行计数，以便确定等待切换的候选。

摘要： The present invention relates to a method for a context transfer in a communication network comprising a plurality of heterogeneous access networks, (220, 221, 222) wherein a mobile terminal is attached to one of the access networks. Further, the present invention relates to a context transfer manager performing the method (220, 600). Moreover, the present invention relates to a mobile terminal specially adapted to perform the provided method for a context transfer. To facilitate a context transfer between heterogeneous access networks, the present invention introduces a context transfer manager generating at least one context based on capabilities and parameters associated to the mobile terminal and capabilities and parameters of the neighboring access networks taking into account the respective access technology (FIG. 5). Further the context transfer manager is common to the heterogeneous access networks in the communication network and performs the context transfers related to a particular mobile terminal.

摘要： The invention relates to a method for mitigating the effects of a DoS attack against a home agent supporting mobility for a plurality of mobile nodes. Furthermore the invention also relates to a home agent, a mobile node and a communication system implementing the method for mitigating the effects of a DoS attack against a home agent supporting mobility for a plurality of mobile nodes. To consider the problem of DoS attacks in the design of a mechanism for improving communication systems enabling mobility of mobile nodes, the invention proposes to configure a plurality of addresses at which the home agent is reachable in a communications network and to assign to each of the mobile nodes at least one of the plurality of home agent addresses. If a denial of service attack is detected by the home agent, the home agent de-configures the home agent address to which data packets of the denial of service attack are destined.
