Telecommunication enhanced mobile IP architecture for intra-domain mobility
First Claim
1. A method for facilitating intra-domain mobility, said method comprising the steps of:
- providing a first network that includes a first agent including location information about a mobile node;
providing a second network that includes two or more subnetworks and a second agent; and
registering the mobile node with the second agent such that the mobile node transitions from any of the subnetworks to another subnetwork without communicating to the first agent information about the transition and without communicating to the second agent information about a security association between the mobile node and the first agent.

Abstract
Methods and systems are provided for facilitating intra-domain mobility. A first network or domain includes a home agent or SIP proxy of a mobile node. A second network includes two or more subnetworks and at least one mobility agent (MA). Each subnetwork includes an associated subnet agent. To communicate, the mobile node first registers with a subnet agent, receives a local care-of-address and a global care-of-address, and then registers with an MA. The mobile node may then provide the global care-of-address to the home agent. The local care-of-address may enable communication with the mobile node without determining a specific route to the mobile node. The global care-of-address received from the subnet agent may include the address of the MA. Accordingly, the mobile node may transition from any of the subnetworks to another subnetwork without communicating to the home agent information about the transition and without communicating to the MA information about a security association between the mobile node and the home agent.

17. A system for facilitating intra-domain mobility, said system comprising:
-
a first network that includes a first agent including location information about a mobile node; and
a second network that includes two or more subnetworks and a second agent, wherein the second agent is programmed to allow the mobile node to transition from any of the subnetworks to another subnetwork without communicating information to the first agent about the transition and without communicating to the second agent information about a security association between the mobile node and the first agent. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
