A content distribution system in which, when it is detected that an incommunicable area is present in a moving direction of a client terminal, the client terminal transmits a change request signal, requesting an increase of the confirmation interval of a keep-alive signal, to the content distribution server before the client terminal enters the incommunicable area. When the change request signal is received during distribution of content data, the content distribution server increases the confirmation interval of the keep-alive signal, thereby allowing the session of content distribution to be maintained while the client terminal is in motion within the incommunicable area.
