PROBLEM TO BE SOLVED: To make it possible to easily update address information of each communication terminal even in the case of addition and revision applied to the communication terminals in a network even when each communication terminal manages address information of the other communication terminals with which each communication terminal performs communication. SOLUTION: A management terminal 20 manages the address information of the communication terminals 31, 32, 33 in the communication network system 10. When a new communication terminal 34 is added to the communication network system 10, the management terminal 20 transmits the address information of the communication terminal 34 to the prescribed communication terminals 31, 33 and transmits the address information of the communication terminals 31, 33 to the communication terminal 34. The communication terminals 31, 33, 34 update respective address information files on the basis of the transmitted address information. COPYRIGHT: (C)2008,JPO&INPIT
