A user management server device (a) registers a contents transmission request when receiving the contents transmission request to an electronic device from a terminal device, (b) determines whether the contents transmission request to the electronic device is registered when there is an inquiry from the electronic device, and (c) transmits the contents transmission request to the electronic device as a response to the inquiry when the contents transmission request to the electronic device is registered. The electronic device makes an inquiry to the user management server device of whether the contents transmission request to the device itself is registered, and when receiving the contents transmission request as the response to the inquiry, transmits the contents specified by the contents transmission request.
