Communication server, radio base station, communication system, and communication method

摘要

A communication server 120 communicates with a radio base station 110 that is capable of being connected to a fixed line 130 by a user. A receiving unit 121 receives station identification information identifying the radio base station 110 and line identification information identifying a fixed line 130 to which the radio base station 110 is connected. An acquiring unit 122 acquires authentication information indicating preliminarily set correlations between the station identification information and the line identification information. A determining unit 123 determines whether a correlation between the station identification information and the line identification information received by the receiving unit 121 coincides with a correlation indicated in the authentication information acquired by the acquiring unit 122. A determination result output unit 124 outputs a determination result of the determining unit 123.
