Abstract: A communication device is provided with: a feature information generation unit that receives a packet transmitted from a piece of equipment that performs packet communication, and consequently generates information representing a feature of the packet; a classification unit that classifies the packet into a packet group on the basis of the information representing the feature and prescribed classification criteria; an extraction unit that extracts one or more pieces of character information from the packet on the basis of prescribed extraction criteria; and an identification information generation unit that generates identification information capable of identifying the piece of equipment that transmitted the packet, such generation executed on the basis of, from among pieces of character information extracted from one or more packets belonging to the same packet group, character information in which the number of patterns pertaining to the structure of the character information satisfies a condition.

Abstract: A communication apparatus is provided with a communication part, a response index calculation part, and a determination part. The communication part is configured to be capable of transmitting a packet to the terminal, via frequency carrier(s) of a base station to which the terminal is connected. The response index calculation part calculates a response index of the packet. The determination part determines the number of frequency carrier(s) used by the terminal in accordance with the result of the response index calculation by the response index calculation part. Determining a number of frequency carriers being used includes determining the number of LTE carrier waves being used by the terminal.
