    摘要： A system and method for efficient state transfer in mobile networks provides improved performance by providing seamless transfer of updated reference state information across network access points during mobile node hand-off. This state transfer processing may be used in an Internet Protocol (IP) network and may include seamless transfer of header compression state.

    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： An apparatus, system, and method are directed to managing connectivity in a network by expediting the ability of a mobile node to send Internet Protocol (IP) packets subsequent to a handover. The mobile node is configured to determine an unconfirmed address for use on an access router. Upon establishing a link-layer connection, and before establishing a network-layer connection with the access router, the mobile node employs the unconfirmed address to send an IP packet to the access router. Employing the unconfirmed address prior to network-layer connectivity enables the reduction of handover latencies. If the access router determines that the unconfirmed address conflicts with an existing address, the access router provides a message to the mobile node indicating the conflict in addresses. In response to the message, the mobile node performs actions to resolve the address conflict.

    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： An apparatus and method are provided in which multiple options are configured to deliver a base-station ID (BSID), which acts as a trigger for an initiation of a handover at an access gateway level. The handover triggers may be based on a proactive handover between at least one mobile station and a gateway and base station in a serving and target networks or on a reactive handover in which the at least one mobile station does not perform any handover preparation prior to the handover. In addition, the handover trigger may be based on a network initiating and controlling the handover.

    摘要： A method is disclosed for a router to provide random assignments of three priorities, each signifying a drop precedence, to packets on a per customer basis. The router determines a sending rate estimate. Then the router marks a packet a priority level based on the sending rate estimate.
