Abstract:
1. A method of forming a generic overlay network for efficient information retrieval in a communications network, comprising the steps of: receiving in a domain router a register request from a mobile communications apparatus, the register request including an Uniform Resource Identifier (URI) or logical name of said mobile communications apparatus; looking-up an address to a next-hop router associated with the URI or logical name; sending the register request to the next-hop router; receiving a reply from the next-hop router; if the reply includes an address to a home router associated with the mobile communications apparatus, sending a reply to the mobile communications apparatus including the address of the home router, said reply initiating the establishment of a connection between the mobile communications apparatus and the home router; storing in a table addresses to clients with currently outstanding, non-answered look-up queries for an URI in a domain controlled by the domain router; and replying to all clients with currently outstanding queries in response to receiving a first query response for a certain URI from a next-hop home router and/or foreign router.
