Inter-proxy communication protocol for mobile IP
First Claim
1. In a first access point, a method of supporting mobility for a node that does not support Mobile IP, comprising:
- sending an inter-proxy request message to an IP address identifying an inter-proxy multicast group, the inter-proxy request message identifying the node and indicating that IP configuration information for the node is requested; and
receiving an inter-proxy reply message from a second access point, the inter-proxy reply message including the IP configuration information, thereby enabling the first access point to send a registration request on behalf of the node using the IP configuration information.

Abstract
Methods and apparatus for ascertaining configuration information for a node are disclosed. A first access point sends an inter-proxy request message to one or more additional access points, the inter-proxy request message identifying the node and indicating that IP configuration information for the node is requested. The first access point then receives an inter-proxy reply message from a second one of the additional access points, the inter-proxy reply message including the IP configuration information, thereby enabling the first access point to send a registration request on behalf of the node using the IP configuration information. In this manner, the Access Points support mobility for a node that does not support Mobile IP.

17. In a second access point, a method of supporting mobility for a node that does not support Mobile IP, comprising:
-
receiving an inter-proxy request message from a first access point, the inter-proxy request message being addressed to an inter-proxy multicast group address and indicating that IP configuration information for the node is requested;
sending an inter-proxy reply message to the first access point, the inter-proxy reply message including the IP configuration information, thereby enabling the first access point to send a registration request on behalf of the node using the IP configuration information. - View Dependent Claims (18, 19, 20, 21)
