For example, the NAS device 10 may have a function of specifying the communication method of the communication terminal device 20. In this case, the CPU 140 included in the NAS device 10 includes a selection unit 141 and a communication method designation unit 143 as functional units.
The communication method designation unit 143 designates the wireless communication method of the communication terminal device 20. Specifically, the communication method designation unit 143 designates the wireless communication of the NAS wireless LAN method as the communication method of the own device by the communication terminal device 20. The communication method designating unit 143 generates, for example, designation information that designates the wireless communication method of the communication terminal device 20, and designates the communication terminal device 20 by NAS wireless LAN wireless communication realized by the Wi-Fi wireless communication unit 110. Generate information. Based on the designation information received from the NAS device 10, the communication terminal device 20 performs wireless communication by the NAS wireless LAN method among the router route method, the LTE route method, and the NAS wireless LAN method.
Therefore, according to the NAS device 10 of the present embodiment, information transmitted and received by the communication terminal device 20 can be aggregated and relayed to the Internet or a mobile communication network.

  The NAS device 10 in this example may be configured to authenticate communication by using the subscriber identifier ID in communication with the communication terminal device 20 by LTE. In this case, the NAS device 10 permits communication with the communication terminal device 20 by LTE when the subscriber identifier ID of the SIM attached to the communication terminal device 20 is registered in the NAS device 10 in advance.

  Further, the NAS device 10 in this example may be configured to authenticate communication by using this subscriber identifier ID in communication with the communication terminal device 20 by Wi-Fi. In this case, the NAS device 10 permits communication with the communication terminal device 20 by Wi-Fi when the subscriber identifier ID of the SIM attached to the communication terminal device 20 is registered in the NAS device 10 in advance. .

  That is, the NAS device 10 communicates only with the communication terminal device 20 registered in advance among various communication terminal devices. With this configuration, the NAS device 10 can restrict access so that an unauthenticated communication terminal device accesses the storage unit and does not read and write data without permission.

  For example, the NAS device 10 performs access authentication for data in the storage unit using the SIM. This SIM is provided by a telecommunications carrier after sufficient measures have been taken for communication security in a mobile communication network. That is, the access authentication by SIM has sufficiently high reliability for communication security. Therefore, according to the NAS device 10 of the present embodiment, with regard to communication security, even with Wi-Fi communication, reliability equivalent to LTE communication can be ensured.

  In each of the above embodiments, the subscriber identifier ID is an example of subscriber information. The NAS identifier ID1 is an example of first subscriber information. The terminal identifier ID2 is an example of second subscriber information.

  In addition, each part with which the NAS apparatus 10 in each said embodiment and the communication terminal device 20 are provided may be implement | achieved by dedicated hardware, and is implement | achieved by memory and a microprocessor. Also good.

  Each unit included in the NAS device 10 and the communication terminal device 20 includes a memory and a CPU (central processing unit), and a program for realizing the functions of the units included in the NAS device 10 and the communication terminal device 20 is stored in the memory. The function may be realized by loading and executing.

  In addition, a program for realizing the function of each unit included in the NAS device 10 and the communication terminal device 20 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. The processing may be performed by doing so. Here, the “computer system” includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and appropriate modifications may be made without departing from the spirit of the present invention. it can. You may combine the structure as described in each embodiment mentioned above.
