SUPPORT FOR MULTI-HOMING PROTOCOLS USING TRANSIENT REGISTRATION AND EXPANDED BINDING REVOCATION MESSAGES

摘要

The present invention solves these problems with a new proxy binding update request and proxy binding acknowledgement messages having new indicators and identification information. Namely, the home agent/local mobility anchor will exchange proxy binding update messages and proxy binding acknowledge messages that include information such as mobile node identification (MN-ID), home network prefix (HNP), but can also include selective information fields such as, access type, handover indicator (HO), and interface identification (interface ID). By including new access type, indicator, and identification information, the local mobility anchor can respond to a binding update request message with a better understanding of the new connectivity request from the mobile node. The invention also includes a binding revocation message with expanded trigger field information .sent from the local mobility anchor to the mobile access gateways so the mobile access gateway can determine if the network resources should be revoked, and the manner in which it can optimize usage of the network resources by revoking the network resources in a certain time and manner.
