Packet analysis method and information processing apparatus

A packet analysis method, comprising:

• acquiring, by a computer, a first packet group and a second packet group at a predetermined location in a network, the first packet group being wirelessly transmitted from a first wireless communication device and received by one of a plurality of wireless base stations connected to the network, the second packet group being wirelessly transmitted from a second wireless communication device and received by one of the plurality of wireless base stations;
• accumulating the first packet group and the second packet group in a memory in an arrival order;
• detecting a consecutive number of packets in which a first packet among the first packet group and a second packet among the second packet group are accumulated alternately and consecutively one packet at a time in a time series;
• and
• determining whether the first wireless communication device and the second wireless communication device are connected to a same wireless base station based on the consecutive number.

An information processing apparatus, comprising:

• a memory;
• and
• a processor coupled to the memory and the processor configured to:
• acquire a first packet group and a second packet group at a predetermined location in a network, the first packet group being wirelessly transmitted from a first wireless communication device and received by one of a plurality of wireless base stations connected to the network, the second packet group being wirelessly transmitted from a second wireless communication device and received by one of the plurality of wireless base stations;
• accumulate the first packet group and the second packet group in the memory in an arrival order;
• detect a consecutive number of packets in which a first packet among the first packet group and a second packet among the second packet group are accumulated alternately and consecutively one packet at a time in a time series;
• and
• determine whether the first wireless communication device and the second wireless communication device are connected to a same wireless base station based on the consecutive number.
