Communication system, communication method and communication device

Abstract

The invention provides a communication system, a communication method and a communication device. The communication system can comprise a network service node NSN and a user service node USN, the NSN and the USN are communicated through an external interface, and the NSN comprises an authentication function entity and / or an access management function entity; the USN is associated with a terminal device or a group of terminal devices, for example, the USN can be only associated with a terminal device or a group of terminal devices, the USN comprises the following functional entities: a data forwarding functional entity, a session management functional entity and a user data storage functional entity, and the functional entities included in the USN communicate with one another through internal interfaces. Based on the functional entities included in the USN, the USN can provide basic network services for the associated terminal device or group of terminal devices. The USN may also be a node in a distributed hash table. According to the communication system provided by the embodiment of the invention, the network complexity can be reduced.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a communication system, a communication method, and a communication device. Background technique [0002] In the 5th Generation (5G) network of the 3rd Generation Partnership Project (3GPP), the core network element entities are extremely large and have many types, resulting in excessive signaling interactions and high costs. At the same time, it also increases the risk point of being vulnerable to attack. SUMMARY OF THE INVENTION [0003] The present application provides a communication system, a communication method, and a communication device, which can reduce network complexity. [0004] In a first aspect, a communication system is provided, the communication system includes: a network service node (NSN) and a user service node (USN), the NSN and the USN communicate through an external interface, and the NSN includes An authentication functional entity and / ...
