Title:
COMMUNICATION SYSTEM, SUBSCRIBER INFORMATION MANAGEMENT DEVICE, INFORMATION ACQUISITION METHOD, NON-TRANSITORY COMPUTER READABLE MEDIUM, AND COMMUNICATION TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/012611
Kind Code:
A1
Abstract:
The objective of the invention is to provide a communication system wherein if a network slicing is applied to a core network, a high security level can be maintained in each of networks as divided. A communication system according to the present disclosure comprises: a subscriber information management device (10) that manages the subscriber information of a communication terminal; and a security device (20) that manages the identity information of the communication terminal and the associated security information used in at least one of network slice systems that can be used by the communication terminal. The subscriber information management device (10) uses the identity information of the communication terminal and the identity information of a network slice system used by the communication terminal to acquire, from the security device (20), the security information used in the network slice system used by the communication terminal.
