RADIO SEGMENT PERFORMANCE MEASURING SYSTEM, AND METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To achieve a radio segment performance measuring system which places a minimum burden on a network with low cost predicted on a protocol stack and a signaling method usually used in a mobile packet communication.

SOLUTION: In a radio segment performance measuring system 1, a passing packet is observed in a wired line 101 between mobile machines 4-1-4-4 of a mobile packet communication system which performs a packet communication by using a confirmation response type protocol and a relay exchange 5. Packet attribute data and a passing time of the passing packet are obtained, and the packet attribute data are classified by a mobile machine identifier. Based on the packet attribute data classified, a downward data transfer packet corresponding to an upward data transfer packet is retrieved, and a packet round-trip routing time is obtained from the confirmation response packet and each passing time of the data transfer packet.
