Abstract

Official abstract text for this publication.

Upon sensing an update of any routing information entry held in a routing information storage unit (A 104 ), an information exchange coordination unit (A 105 ) references a node information storage unit (A 102 ), and if a node information entry corresponding to the updated routing information entry does not exist, acquires the corresponding node information entry from another communication terminal (A 1 b ). Alternatively, upon sensing an update of any node information entry held in the node information storage unit (A 102 ), the information exchange coordination unit (A 105 ) references the routing information storage unit (A 104 ), and if a routing information entry corresponding to the updated node information entry does not exist, acquires the corresponding routing information entry from another communication terminal (A 1 b ). This provides a communication terminal for acquiring both the node information entry and the routing information entry relating to a specific communication terminal substantially at the same time.

First claim
