摘要： A method and system for supporting mobile routers in Internet Protocol version 6 (IPv6) is provided. A mobile router obtains a care-of-address associated with an address configuration. The mobile router registers the care-of-address with a home agent. A bi-directional tunnel is established between the mobile router and the home agent. Packets are then forwarded via the bi-directional tunnel.

摘要： A system and method is provided that enables the transfer of policy resource tokens (PRT) in the process of a handover of a mobile node in a wireless network. The system includes a granting agent that grants the PRT to a first access router to enable the mobile node to access network resources. In one embodiment, in the process of handing over the mobile node, the first access router provides the PRT to the second access router, thereby reducing data latency, and a disruption for an application executing on the mobile node. In another embodiment, the mobile node provides the PRT to the second access router after connectivity is established. A PRT data structure also is provided that includes a data field of profile types. A profile type describes context authorization information for granting access to a network resource.
摘要翻译：提供了一种系统和方法，其能够在无线网络中的移动节点的切换过程中传送策略资源标记（PRT）。该系统包括授权代理，其将PRT授予第一接入路由器以使得移动节点能够访问网络资源。在一个实施例中，在移交移动节点的过程中，第一接入路由器将PRT提供给第二接入路由器，由此减少数据等待时间，以及对在移动节点上执行的应用的中断。在另一个实施例中，移动节点在建立连接之后将PRT提供给第二接入路由器。还提供了包括简档类型的数据字段的PRT数据结构。配置文件类型描述用于授予对网络资源的访问权限的上下文授权信息。

摘要： The present invention provides location privacy against third parties while allowing route-optimized communication between the correspondent node and the mobile node. The mobile node's home address is hidden from an external observer thereby thwarting traffic analysis based attacks where a Home Address is correlated with a Care of Address of a mobile node (MN). A “privacy label” is used in place of a home address associated with the mobile node. The privacy label is supplied by the mobile node to the correspondent node in a way that that allows the privacy label to be bound to the home address, but does not allow the home address to be visible during the exchange. The privacy label may be also used to help prevent against replay attacks.
摘要翻译：本发明提供了针对第三方的位置隐私，同时允许通信节点和移动节点之间的路由优化通信。移动节点的归属地址被外部观察者隐藏，从而阻止基于业务分析的攻击，其中归属地址与移动节点（MN）的地址关联相关联。使用“隐私标签”代替与移动节点相关联的归属地址。隐私标签由移动节点以允许隐私标签绑定到家庭地址的方式提供给通信节点，但是不允许家庭地址在交换期间可见。隐私标签也可用于帮助防止重放攻击。

摘要： A method for updating filters, at a Packet Data Serving Node, with a care-of-address associated with at least one of a mobile station or a correspondent node. The method includes the steps of implementing a soft filtering rule at a Packet Data Serving Node and receiving, by the Packet Data Serving Node, a care-of-address that is associated with at least one the mobile station and a correspondent node. The method also includes updating, by the Packet Data Serving Node, filters with the care-of-address to correctly identify flows belonging to a particular session during Mobile IP use. The method further includes filtering, by the Packet Data Serving Node, packets including a care-of-address that is associated with one of the mobile station and the correspondent node.

摘要： When mobile node is connected to an access point outside the private network, a tunnel is formed between the mobile node and a home agent on the private network for the transfer of packets. When, the mobile node roams into a region accessible to the private network, the mobile node is connected to the private network using a private network access point while maintaining the tunnel between the mobile node and the home agent.

摘要： A system for selectively updating an address of a mobile node capable of roaming in a home communication network and at least one visited network. The system including a database for storing at least one data entry which is a mapping between a humanly-readable identifier indicating the mobile node and a machine-readable identifier indicating a physical address at which the mobile node can be reached. A home agent in the home network has a connection to the database, and is operable to receive an update message from the mobile node when the mobile node roams into the visited network. Also there are units for determining whether the machine-readable identifier of the at least one entry in the database should be updated, wherein the database is updated if the update message additionally includes the humanly-readable identifier.
