As described above, in the management apparatus according to the present embodiment (in this example, the NAS apparatus 10), the registration unit 131 transmits the permission request information RQ to the permission request information RQ received by the Wi-Fi wireless communication unit 110. The terminal identifier ID2 of the communication terminal device 20 to be registered is registered in the permission identification information WL. The content communication determination unit 132 determines whether or not to perform content communication with the communication terminal device 20 based on whether or not the terminal identifier ID2 of the communication terminal device 20 is registered in the permission identification information WL. The Wi-Fi wireless communication unit 110 and the LTE wireless communication unit 120 perform content communication with the communication terminal device 20 based on the determination result of the content communication determination unit 132.
Therefore, according to the NAS device 10 of this embodiment, even if the user is not good at setting the NAS device 10 or the communication terminal device 20, the communication terminal device 20 that permits content communication to the NAS device 10 is registered.
