Communication analysis apparatus and communication analysis method

A communication analysis method for analyzing data acquired from a transmission path of a communication network, the communication analysis method comprising:

• a step of acquiring a plurality of division data, which are obtained by dividing the data into predetermined lengths;
• a division organization information addition step of adding division organization information which includes division unit information for defining the predetermined lengths and division position information being information about start positions and end positions of the division data in the data, to the division data;
• and
• a step of synchronizing data, wherein
• the data synchronization step includes:
• a division organization information-added communication message storage step of storing one or more division organization information-added communication messages generated by adding message communication unit division organization information,
• a division organization information-added waveform signal storage step of storing one or more division organization information-added waveform signals generated by adding waveform communication unit division organization information and
• a synchronization determination step of having one or more synchronization determination conditions, and
• when the message communication unit division organization information and the waveform communication unit division organization information meet the synchronization determination condition, the synchronization determination means sets the basic ID of the waveform communication unit division organization information as the association ID of the message communication unit division organization information, and sets the basic ID of the message communication unit division organization information as the association ID of the waveform communication unit division organization information.
