  • End-to-end location privacy in telecommunications networks
    Patent number: 6999437
    Abstract: A method and system for routing messages between hosts while maintaining end-to-end location privacy are disclosed. In order to make routing more efficient, while maintaining location privacy, an encapsulation cache may be created in access routers that have a trust relationship with the respective home networks of the hosts. The encapsulation cache can be used to store home-address to care-of-address correspondences so that the access router, when a host is roaming, can route a message directly to the message's intended recipient, yet still maintain location privacy for the sending host by replacing the host's care-of address at the roaming network with the host's home address.
