Communication speed estimation apparatus, communication speed estimation method, and program

A communication speed estimation method executed by a communication speed estimation apparatus including a computer and a storage unit, comprising:

• a first step of generating communication log information representing a history of communication executed by a user, and storing the communication log information in a communication history information storage unit;
• a second step of calculating, based on the stored communication log information, throughput result information for each of a server, a network and a user terminal that were used for the communication for each time slot, and storing the calculated throughput result information in a quality information storage unit, and
• a third step of, when the user performs new communication, in advance, reading out corresponding throughput result information from the quality information storage unit based on at least one of a terminal, a server and a network that the user intends to use, and a time slot including a time when the user intends to perform communication, and estimating a communication speed in the new communication based on the read-out throughput result information.
