摘要： Methods and apparatus for performing proxy registration on behalf of a node with a Home Agent supporting Mobile IP are disclosed. A first registration request is composed on behalf of the node and transmitted to the Home Agent via a first Local Mobility Anchor, wherein the first Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with the first Local Mobility Anchor. When the node moves within a region or between regions, the node is re-registered. Specifically, a second registration request is composed and transmitted to the first Local Mobility Anchor when the node moves within the region associated with the first Local Mobility Anchor. When the node moves into a second region associated with a second Local Mobility Anchor and outside the first region associated with the first Local Mobility Anchor, a second registration request is composed and transmitted to the Home Agent via the second Local Mobility Anchor, wherein the second Local Mobility Anchor is a regional controller via which registration is performed when the node moves within a region associated with second first Local Mobility Anchor.

摘要： Methods and apparatus for performing optimizations for a mobile network device such as a Mobile Node or Mobile Router supporting multiple links to a Home Agent (or Correspondent Node in a Mobile IPv6 environment) are disclosed. During the registration process, link characteristics are transmitted in the registration request. From the link characteristics, it is possible to determine whether the mobile network device has roamed from a high to a low bandwidth link, or vice versa. A first set of optimizations may be performed when the mobile network device has roamed from a high to a low bandwidth link, while a second set of optimizations may be performed when the mobile network device has roamed from a low to a high bandwidth link. Some optimizations may be performed during the establishment of a TCP session, while others may be performed during or upon completion of the Mobile IP registration process.

摘要： Methods and apparatus for optimizing Mobile VPN communications are disclosed. When a data packet is transmitted between a Mobile Node that is a member of a VPN and a Correspondent Node, the data packet is transmitted between the Mobile Node and a Home Agent via a Mobile IP tunnel without transmitting the data packet via a VPN tunnel. However, the data packet is transmitted between the Home Agent and a VPN headend via a VPN tunnel.

摘要： Methods and apparatus for establishing an optimized route between a Mobile Node and a Correspondent Node are disclosed. In particular, a Correspondent Node is notified of the location of a Mobile Node, thereby enabling the Correspondent Node to communicate directly with the Mobile Node. This is accomplished by sending a HOTi message protected in IPSec transport mode from the Mobile Node to a Home Agent associated with the Mobile Node for modification and transmission of a modified HOTi message to the Correspondent Node. The Mobile Node then receives a HOT message protected in IPSec transport mode from the Home Agent associated with the Mobile Node, the HOT message being received from the Home Agent associated with the Mobile Node after modification has been performed by the Home Agent on an initial HOT message received by the Home Agent from the Correspondent Node.

摘要： Methods and apparatus for supporting a session in Mobile IP are disclosed. A Mobile Node sends a first Mobile IP message identifying the Mobile Node to a Home Agent, wherein the first Mobile IP message indicates to the Home Agent that the Mobile Node is requesting dynamic configuration of a Mobile-Home authentication key to be shared between the Mobile Node and the Home Agent during the session. A Mobile-Home authentication key to be shared between the Home Agent and the Mobile Node is obtained or generated by the Mobile Node and the Home Agent, where the Mobile-Home authentication key is not valid after the session has ended or during another session. The Home Agent sends a second Mobile IP message to the Mobile Node, the second Mobile IP message including a lifetime associated with the session, wherein the lifetime indicates a lifetime of the key, thereby enabling the Mobile Node to register with the Home Agent using the Mobile-Home authentication key to be shared between the Home Agent and the Mobile Node during the session.
