Abstract: In order to provide a communication session log analysis device allowing integration of communication session logs that makes it p to provide web session time with which quality of user experience can be evaluated with high precision, a communication session log analysis device according to the present invention that updates information relating to a web session includes: a web session integration means for integrating, when time elapsed from a start time of a reference communication session to a start time of one communication session is equal to or less than a threshold value, the one communication session into the same web session as the reference communication session, a threshold value setting means for setting the threshold value, based on a predetermined probability distribution, and a filtering means for extracting the web session determined as valid by statistical testing based on statistical information relating to a configuration of the web site.

Abstract: A communication apparatus includes an accumulation means 501 that temporarily accumulates communication data in a previous stage of transmission to the MAC layer, an estimation means 502 that estimates an amount of transmittable data, which is an amount of data that can be transmitted in the MAC layer in a predetermined period, by using a radio wave index that is an index related to a radio wave in the frequency and/or a communication index that is an index related to wireless communication using the frequency, the indices being measured by an own apparatus or a wireless device including a MAC layer used by the own apparatus, and a control means 503 that controls, on the basis of an estimation result of the amount of transmittable data, a data flow of when the communication data accumulated in the accumulation means 501 is transmitted to a lower layer.
