Description

The present invention relates to a communication system having a wireless communication device and a terminal device.

One of the methods for the terminal device to connect to the Internet is to use a wireless network. Examples of the wireless network include a wireless LAN (Local Area Network). A wireless LAN is a communication network that connects a terminal device to the Internet via a wireless communication device such as an access point.

When connecting to the wireless network, the terminal device makes an authentication request to the wireless communication device. Here, it takes time and effort for the user to register personal information and the like for each wireless network to be connected. Therefore, there is a technique for preliminarily holding personal information transmitted by a terminal device for connecting to a wireless communication device (Patent Document 1).

Japanese Unexamined Patent Publication No. 2015-146651

However, if the authentication request is made by transmitting the personal information from the terminal device to the wireless communication device as in the conventional case, the personal information may be leaked.

Therefore, in the present invention, the terminal device is within the radio wave output range of the wireless communication device.
The first identification information regarding the terminal device is transmitted to the link node between the user management system and the application system in the wireless communication device, and the first identification information is transmitted.
The second identification information regarding the terminal device is transmitted from the cooperation node to the user management system.

This makes it possible to connect the terminal to the wireless network without transmitting the user's personal information from the terminal device to the wireless communication device.

The server 51 accesses the memory 522 in the storage 52 via the storage access unit 513 and the interface unit 521 under the control of the control unit 514. In this way, the server 51 searches the memory 522 for the database that needs processing. Then, the resource allocation unit 515 instructs the terminal device 3 in which the resource remains to process the data via the interface unit 511.

The timing of this transmission is described as step S7-1 in the present embodiment, but it may be performed at any timing of steps S1 to S7. Further, the information based on the remaining resources may be directly transmitted by the terminal device 3 to the distributed computing system 5.

Next, the distributed computing system 5 instructs the terminal device 3 to process data (S7-2). At this time, it is preferable that the distributed computing system 5 instructs the processing of data according to the size of the remaining resources of the terminal device 3.

Then, the terminal device 3 processes the commanded data (S7-3).
