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.
