Problems solved by technology

[0004] With the rapid development of my country's wireless communication industry, traditional centralized wireless networks are increasingly difficult to meet the explosive growth of wireless users and ubiquitous connection needs
In the current distributed spectrum resource sharing and access architecture, due to many problems such as buyer-seller trust and network security, most spectrum resource sharing and access services are still carried out offline in the form of spectrum auctions, and usually only for cellular network resources

Embodiment Construction

[0023] refer to figure 1 As shown, the internal structure of a certain three consecutive blocks in the block chain structure adopted by the present invention is shown. Taking the block numbered N+1 as an example, the block mainly includes four parts of data: the previous block hash value, block data, random number and current block hash value. The block data includes multiple data types such as virtual currency transactions and smart contracts, and the current block hash value is jointly hashed by using the previous block hash value, block data and random numbers. Greek operation can be obtained. The random number is continuously adjusted by the miners participating in mining in the blockchain miner network until the calculated hash value of the current block is less than a specific difficulty value, and the first miner who calculates that the above conditions are met gets the latest Block accounting rights. The blocks are connected to each other through the block hash valu...

Abstract

The invention discloses a novel distributed access network architecture based on a block chain. The architecture comprises RRH and RRU used as access points in a wireless radio frequency communicationsystem, a user, digital spectrum resources managed by the RRH and the RRU respectively, a miner network formed by miners for maintaining a block chain, and a novel distributed mechanism used for managing sharing and access of the wireless spectrum resources. And the RRH and the RRU equipment provide wireless spectrum resource sharing and access services for the user, and the service process is controlled by a novel distributed mechanism for managing network access. The invention provides a novel distributed access network architecture based on a block chain. The RRH or the RRU in the architecture and a user can perform safe and reliable spectrum resource transaction in an untrusted environment.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a novel distributed access network architecture based on blockchain. Background technique [0002] Since the emergence of Bitcoin (Bitcoin), a cryptocurrency, in 2008, the supporting technology behind it: blockchain, has officially appeared in front of the public. Bitcoin-based electronic cash transactions break the original mode of legal tender as the only transaction token, and create a new decentralized transaction mechanism. Through the principles of cryptography and distributed consensus mechanism, transactions are solidified end to end. The blocks are stored in each node of the network, and its characteristics of decentralization, security, and non-tampering have brought great value. In the past ten years of development, blockchain technology has gone through several stages, from the 1.0 era that fully serves digital currency and the 2.0 era represen...
