Security mechanisms are disclosed that protect the integrity of the candidate access node discovery procedures in a mobile communication network. In accordance with an aspect of the invention, an access node stores information on candidate access nodes in the mobile communication network and updates the information only after verifying information provided by a mobile terminal after a handoff from one access node to another access node. In accordance with another aspect of the invention, the information on candidate access nodes in the mobile communication network are associated with a particular mobile terminal and stored at the mobile terminal in a candidate access node list.

Secure candidate access router discovery method and system

A guest station on a foreign network is provided IP access by the foreign (i.e., hosting) network without changes to the guest station, including settings for IP address, next-hop-router (gateway), and netmask. An access router automatically detects guests and their home-IP-address and assigns a local care-of address to every guest. For outgoing traffic, the router replaces the guest's original/home IP address with the care-of address, and the reverse is performed for incoming traffic. IP traffic may thus be initiated, and responses received at the temporary current location without having to change its IP address.
