Wireless communications system, base station, mobile station, and processing method

A data management device manages personal data to which consent information indicating a data user authorized as a receiver has been added. The data management device includes: a cache memory and a processor. When personal data requested by a data user is stored in the cache memory, the processor acquires the requested personal data from the cache memory. When personal data requested by the data user is not stored in the cache memory, the processor acquires the requested personal data from a data holder. The processor decides based on consent information added to the personal data acquired whether to provide the personal data to the data user. When the data management device acquires new personal data from a data holder, the processor decides whether to store the new personal data in the cache memory based on consent information added to the new personal data.

A wireless communications system includes a first wireless-communications-apparatus that controls a second wireless-communication by a controller for a first wireless-communication; a second wireless-communications-apparatus capable of the second wireless-communication; and a third wireless-communications-apparatus capable of data transmission with the first wireless-communications-apparatus via the first or second wireless-communication, and that transmits to the first wireless-communications-apparatus, a control message including an address thereof for the second wireless-communication. When data is transmitted from the first wireless-communications-apparatus to the third wireless-communications-apparatus through the second wireless-communications-apparatus via the second wireless-communication, a processor in the first wireless-communications-apparatus for the first wireless-communication transfers the data to the second wireless-communications-apparatus through an adaptation sublayer and notifies the second wireless-communications-apparatus of the address acquired from the control message. The data is already processed in a convergence layer for performing the first wireless-communication. The second wireless-communications-apparatus transmits the data to the third wireless-communications-apparatus via the second wireless-communication, using the notified address.

An authorization apparatus includes a memory configured to store attribute information associating an identification information of data and information indicating an attribute of the data, the data being stored in a data server, a processor configured to generate an access token in association with an extraction condition to be used for extracting the data to be obtained by a terminal, and a communicator configured to receive a target access token from the data server, wherein when receiving the target access token, the processor is configured to extract identification information of data pieces satisfying the extraction condition associated with the target access token, and generate a list of identification information of the data to be disclosed to the terminal using a target access token, and the communicator transmits the list to the data server.
