Authorized spectrum sharing system and method in massive Internet of Things equipment access environment

Abstract

The invention discloses a quick authorized spectrum sharing system in a massive Internet of Things equipment access environment. The quick authorized spectrum sharing system comprises an authorized spectrum management layer, an authorized spectrum allocation protocol layer and a user behavior security layer, the authorized spectrum management layer comprises an authorized user behavior database and a secondary user behavior database; the authorized spectrum management is the core of the FLSS scheme; the authorized user and the secondary user comply with a sharing constraint rule managed by theLSM; the authorized spectrum allocation protocol layer executes an LSA protocol; and the user behavior security layer is used for supporting an LSA protocol and constraining authorized user behaviorsand secondary user behaviors. The method comprises the following steps: the step 1, authorized spectrum management; the step 2, executing an LSA protocol; the step 3, constraining authorized user behaviors and secondary user behaviors. Frequency spectrum sharing efficiency can be effectively improved, the method can be used for verifying user identities of a large number of mobile devices, and expandability is already used for evaluating individual trust coefficients.

Description

technical field [0001] The invention belongs to the technical field of spectrum sharing in an Internet of Things device access environment, and specifically relates to an authorized spectrum sharing system and a method thereof in a massive Internet of Things device access environment. Background technique [0002] With the massive increase in the number of mobile terminals, 5G technology will be put into use around 2020. In the future, the total number of mobile terminals connected to the 5G communication network will reach 100 billion. It is estimated that by 2020, the number of global mobile terminals will exceed 10 billion. The number of global IoT device connections will also grow rapidly, and the global population will reach 7 billion by 2020. By 2030, the number of global IoT device connections will be close to 100 billion, of which China will exceed 20 billion. With the increase in the number of massive IoT devices, the shortage of spectrum resources is becoming mo...
