PATH OPTIMIZATION DEVICE, MOBILE TERMINAL AND COMMUNICATION SYSTEM USING THE SAME, PATH OPTIMIZING METHOD, AND PATH OPTIMIZATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To eliminate execution of useless path optimization processing. SOLUTION: This path optimization device includes: an optimization processing section 4 for optimizing a communication path with a communication partner terminal; an NG (No Good) list registering section 6 for registering a communication partner terminal which the optimization processing section 4 fails to optimize; and an NG partner information eliminating section 8 for eliminating the communication partner terminal registered in the NG list registering section 6 from the NG list registering section 6 when the communication partner terminal satisfies a prescribed list elimination condition.
