摘要： The invention relates to a method for reducing the header size of data packets exchanged between a Mobile Node and its Home Agent. Different sort of headers are utilized between a Correspondent Node and the MN's HA, and between the MN and its HA. The sort of header used between the MN and its HA allows to reduce the header size of exchanged packets on said data path section, as only one header is necessary, compared to the necessity of two headers of the previous sort, used between the CN and the HA. To achieve this, a modified route optimization procedure is performed between the MN and its HA, wherein the HA participates in the RO on behalf of the CN. Thus, the RO remains transparent for the CN, while the MN thinks normal RO is happening. The invention also relates to several network entities that participate in the method.
摘要翻译：本发明涉及一种用于减少在移动节点和其归属代理之间交换的数据分组的报头大小的方法。在对应节点和MN的HA之间以及MN和其HA之间使用不同类型的报头。在MN和其HA之间使用的报头类型允许在所述数据路径部分上减少交换的分组的报头大小，因为与CN和CN之间使用的先前分类的两个报头的必要性相比，仅需要一个报头医管局为了实现这一点，在MN和其HA之间执行修改的路由优化过程，其中HA代表CN参与RO。因此，RO对CN保持透明，而MN认为正常的RO正在发生。本发明还涉及参与该方法的几个网络实体。

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.

摘要： The current application concerns a method, mobile node, home agent and system for route optimisation between a mobile node and at least one correspondent node in a packet switched network, wherein a route via a first home agent is redirected via a second home agent. The mobile node sends an extended home test initiation message comprising following information: authentication data, an address of the correspondent node, a first home address and a second home address. The first home agent receives the extended home test initiation message and sends an extended home test message to the second home agent, the extended home test message comprising the information from the extended home test initiation message. The second home agent receives the extended home test message and a communication is routed between the mobile node and the at least one correspondent node via the second home agent.

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 configuring a context for a connection delivering a packet data service to a mobile terminal via a target wireless access network. The mobile terminal is initially connected to an originating wireless access network and the packet data service may be provided to the mobile terminal via the originating wireless network. Moreover, the invention provides an authentication server, a packet data gateway and a packet data service support node which participate in the context configuration method. To provide a method that allows establishing connection for packet service delivery to a mobile terminal from a wireless access network, as for example a UMTS, as fast as possible the invention suggests to preconfigure service provision of the packet data service via the target wireless access network by establishing a context prior to the mobile terminal connecting to the target wireless access network.

摘要： The invention relates to a method for managing the mobility of a mobile node that moves to a different network, but keeps the same IP address. It is proposed to perform route optimization by a Proxy MIP agent on behalf of the MN, thereby shortening the data-path while allowing network-based mobility. At session setup with a correspondent node, the PCC system in the home network decides whether route optimization is to be performed for the communication session. The PMIPa requests relevant information for the route optimization, including the decision for route optimization and the addresses of MN and CN, from the PCC system in the home network, when the MN attaches to the new network area. Accordingly, route optimization is performed by using the Return Routability Procedure according to MIPv6, thereby applying the MN's IP address as Home Address, and the PMIPa's address as Care-of Address of the MN.

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.
