Document Type and Number:
Japanese Patent JP3916542
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve flexibility and availability and to improve the availability of real time communication (for example, communication requiring immediacy in calling and reply as in IP telephone).
SOLUTION: An address assignment system has a dynamic address assignment server for dynamically assigning an address selected out of unassigned addresses among addresses that the dynamic address assignment server itself stores each time an assignment request is received from a communication terminal existing within a prescribed management range. The address assignment system is provided with an address assignment relay system located between the dynamic address assignment server and a plurality of communication terminals. In addition, the address assignment relay system performs address reservation processing for securing addresses for the plurality of communication terminals before each of the communication terminals actually transmits an assignment request in cooperation with the dynamic address assignment server.
