Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 1, the block chain-based multiparty spectrum real-time transaction method provided in this embodiment includes the steps of:
s100, the first intelligent agent and the second intelligent agent determine target transaction data of frequency spectrum transaction through a game, generate a frequency spectrum transaction instruction and send the frequency spectrum transaction instruction to a server.
The first intelligent agent and the second intelligent agent are respectively intelligent agents of a spectrum owner and a spectrum demand party (generally a network operator), the intelligent agents (intelligent agents) are programs for regularly collecting information or executing services, do not need manual intervention, have high intelligence and autonomy, can actively collect the most interesting information for users through an intelligent agent server according to the criteria defined by the users, then push the processed information to the users on time by using an agent communication protocol, can presume the intention of the users, and autonomously make, adjust and execute work plans. In this embodiment, the spectrum transaction participants submit service contents and service requirements through respective intelligent agents, each spectrum transaction participant defines a relevant criterion of spectrum transaction, and the corresponding intelligent agent performs criterion data processing of spectrum transaction.
The first intelligent agent and the second intelligent agent may find each other through a trading platform, for example, the first intelligent agent may issue its own spectrum resource data through the trading platform, the second intelligent agent searches the spectrum resource data on the trading platform to find the first intelligent agent, the second intelligent agent may initiate a spectrum resource purchase request to the first intelligent agent, and the second intelligent agent receives the purchase request sent by the first intelligent agent to construct a game. In this embodiment, the first intelligent agent is a leader and the second intelligent agent is a follower.
The target transaction data comprises frequency spectrum price and bandwidth demand, the first intelligent agent and the second intelligent agent determine the target transaction data of the frequency spectrum transaction through gaming, and the target transaction data comprises the following steps:
s110, when the game starts, the first intelligent agent sends out first transaction data;
s120, the second intelligent agent calculates second transaction data according to the first transaction data and sends the second transaction data;
s130, the first intelligent agent updates the first transaction data according to the second transaction data;
s140, the first intelligent agent determines whether the game is converged, if yes, the first intelligent agent determines that the updated first transaction data and the second transaction data are the target transaction data, if not, the first intelligent agent sends the updated first transaction data, and the second intelligent agent continues to execute the steps of calculating and sending the second transaction data according to the first transaction data sent by the first intelligent agent until the game is converged.
The target transaction data comprises first transaction data and second transaction data, the first transaction data is frequency spectrum price, and the second transaction data is bandwidth demand. As shown in fig. 2, there may be a demand for purchasing a spectrum sent by multiple network operators to the same spectrum owner at the same time, where the first intelligent agent dynamically adjusts a unit bandwidth price by performing a game with an intelligent agent of each network operator to achieve reasonable allocation of spectrum resources, and when the game starts, the first intelligent agent first sends preset first transaction data, that is, preset initial spectrum pricing, and the second intelligent agent calculates and sends second transaction data according to the first transaction data, specifically including:
the second intelligent agent obtains load data of a network operator, and determines the second transaction data according to the first transaction data and the load data.
The network operator is a network operator corresponding to the second intelligent agent, and the process of calculating the second transaction data according to the first transaction data and the load data can be regarded as a sub-game process, and the process is based on the purpose of maximizing the benefits of the network operator to select the optimal amount of the required purchase bandwidth. The load data is calculated according to the number of requested accesses of the cellular users and the internet of things devices within the service range of the network operator, and specifically, within the service range of each network operator, the cellular users and the internet of things devices may simultaneously use a licensed frequency band for uplink transmission, but need to follow a coexistence access principle: each cellular user uses orthogonal signals which are not interfered with each other, the Internet of things equipment randomly multiplexes a plurality of sub-channels for transmission, after the cellular users and the Internet of things equipment are accessed to a network operator, the cellular users and the Internet of things equipment can be charged only when the transmission rate exceeds a specific threshold value, the network operator can guarantee the access and the transmission of the cellular users in a limited way, and the Internet of things equipment can be considered after all the cellular users are met. In the spectrum sharing process, the network operator publishes access cost and a rate threshold value, subordinate cellular users and Internet of things equipment determine whether to send an access request according to self needs, and the network operator acquires the load data according to the received access request.
Specifically, the corresponding relationship between the load data, the frequency spectrum price, and the bandwidth demand may be established in advance, and after the load data and the first transaction data are obtained, the corresponding second transaction data may be determined according to the corresponding relationship, where the corresponding relationship may be established by means of big data analysis, historical data summarization, and the like.
After determining the second transaction data, the second intelligent agent may further determine a benefit corresponding to the current second transaction data according to a preset first benefit function, for example, under a bandwidth B _ m ^ the maximum number of users that can be served by the network operator is N _ m ^ so that a benefit U _ m may be calculated through a benefit function, for example, U _ m ═ P _ N _ m ^ P _ t _ B _ m ^ where P is an access price charge of the user and P _ t is a current spectrum price (i.e., the first transaction data).
After receiving the second transaction data sent by the second intelligent agent, the first intelligent agent updates the first transaction data according to the second transaction data, and the first intelligent agent updates the first transaction data according to the second transaction data, which specifically includes:
and the first intelligent agent updates the first transaction data through a preset function according to the second transaction data.
After receiving the second transaction data, the first intelligent agent first calculates the profit corresponding to the second transaction data according to the second transaction data, and the profit corresponding to the second transaction data calculated according to the second transaction data may be obtained by a preset benefit function, which may be but is not limited to a benefit function common in the prior art, for example, by a preset benefit function: and U _ w _ t max (Σ _ (M ═ 1) ^ M (B _ M ^), B ^ tol) -C are used for calculating the corresponding profit of the second transaction data, wherein Σ _ (M ^ 1) ^ M (B _ M ^) is the total bandwidth requirement of the M network operators in the area, P _ t is the current spectrum price (namely the first transaction data), B ^ tol is the total bandwidth owned by the spectrum provider, and C is the cost. And updating the first transaction data through a preset function according to the income corresponding to the second transaction data, wherein the preset function can be but is not limited to a price iterative formula common in the prior art, such as: and P (t +1) is P _ t + delta _ t (Sigma (M ^ 1) M (B _ M ^) B ^ tol), wherein P (t +1) is the updated first transaction data, and delta _ t is the step size parameter of the t iteration and is used for controlling the amplitude of the price change.
The first intelligent agent determining whether the game converged, comprising:
the first intelligent agent determines whether the updated first transaction data and the first transaction data sent last time are smaller than a preset threshold value;
and if so, determining that the game is converged, and if not, determining that the game is not converged.
In this embodiment, specifically, if | P _ (t +1) -P _ t | ≦ is true, the game is considered to have converged, the first intelligent agent does not calculate new pricing any more, and the game ends; otherwise, the first intelligent agent publishes a new pricing P _ (t +1) to the second intelligent agent, and the game continues to iterate for the t +1 th time. Wherein P _ (t +1) is the updated first transaction data, P _ t is the first transaction data sent by the first intelligent agent last time, and epsilon is a preset threshold.
After the game is converged, the first transaction data and the second transaction data are not changed any more, namely target transaction data are determined, if the game is not converged, the first intelligent agent sends out the updated first transaction data, and the second intelligent agent continues to determine new second transaction data according to the first transaction data sent out by the first intelligent agent. For ease of understanding, the process of gaming can be seen in fig. 3.
After the target transaction data is determined, the first intelligent agent and the second intelligent agent reach a transaction intention, in order to ensure transaction safety, in this embodiment, a transaction of the first intelligent agent and the second intelligent agent is performed on a blockchain constructed by a third party, specifically, after the first intelligent agent and the second intelligent agent determine the target transaction data, a spectrum transaction instruction is generated and sent to a server, the server may be a server of the transaction platform, and the server serves as a trusted third party to construct a blockchain and perform block packaging.
Referring to fig. 1 again, the block chain-based multiparty spectrum real-time transaction method provided in this embodiment further includes the steps of:
s200, the server constructs a block chain, and the consensus of the block chain is achieved by each intelligent agent of the participant of the spectrum transaction.

The third intelligent agent and the fourth intelligent agent may also publish spectrum transaction service data on the transaction platform, and the second intelligent agent or the first intelligent agent may also search spectrum transaction service data on the transaction platform, and determine the target transaction data after determining the third intelligent agent and the fourth intelligent agent participating in the current spectrum transaction.
The method comprises the steps that all participants of the frequency spectrum transaction need to access a transaction platform after identity authentication, service provision and service requirement information is submitted to respective intelligent agents, and the transaction platform can perform credit evaluation and the like on the participants on the transaction platform according to historical transaction data of the participants of the frequency spectrum transaction.
The trading platform can provide trading templates, different processes are set for different specific trading types, and each intelligent agent can call different trading templates to achieve trading interest according to own requirements to generate the frequency spectrum trading instruction.
And S300, each intelligent agent calls the intelligent contract deployed on the block chain respectively to process the spectrum transaction data.
After the server creates the blockchain, one of the intelligent agents deploys an intelligent contract on the blockchain. In this embodiment, since the intelligent agent corresponding to the spectrum owner, that is, the first intelligent agent, is lightly loaded, it is the first intelligent agent that deploys the intelligent contract on the blockchain. Of course, it is understood that, in the case of meeting the business requirements of the intelligent agents, the intelligent contracts may be deployed on the blockchain by any one of the intelligent agents.
Each intelligent agent respectively calls the intelligent contracts deployed on the blockchain to perform spectrum transaction data processing, and the method comprises the following steps:
s310, inputting transaction data when one of the intelligent agents deploys the intelligent contract, and calling corresponding contract functions in the intelligent contract and inputting corresponding transaction data by other intelligent agents in each intelligent agent respectively;
and S320, after the transaction is finished, the intelligent contracts adjust the token amount in the accounts of the intelligent agents according to the transaction data input by the intelligent agents.
Specifically, each function of the intelligent contract is preset to be completed, as shown in fig. 3, one of the intelligent agents inputs transaction data when deploying the intelligent contract, in this embodiment, the first intelligent agent (the intelligent agent of the Spectrum owner) creates the intelligent contract and inputs corresponding transaction data, such as a Spectrum transaction price and a deposit value, the other intelligent agents in the intelligent contracts respectively call the corresponding contract function in the intelligent contract, input transaction data, such as the second intelligent agent (the intelligent agent of the Spectrum demander) calls a Spectrum _ buy () function, inputs a deposit value, the third intelligent agent (the intelligent agent of the radio manager) calls a confirm _ rule () function, inputs a supervision fee value and a deposit value, the fourth intelligent agent (the intelligent agent of the financial manager) calls a confirm _ void () function, and so on, inputting the value of the financial security fee and the value of the deposit. Of course, it should be understood that the above functions are only examples, and the present invention is not limited to the above function names.
In a transaction based on a blockchain, the settlement is performed by using a token, the first intelligent agent or the second intelligent agent may obtain a corresponding token from the fourth intelligent agent in advance to store the token in a corresponding account, after the transaction is finished, the first intelligent agent or the second intelligent agent may detect a transaction result and call a corresponding contract function to enable the intelligent contract to adjust the amount of the token in the account of each intelligent agent according to transaction data input by each intelligent agent, in this embodiment, in order to ensure transaction security, the intelligent contract adjusts the amount of the token in the account of each intelligent agent according to the transaction data input by each intelligent agent, and the method includes:
and the third intelligent agent calls a corresponding contract function according to the transaction result so that the intelligent contract adjusts the amount of the token in the account of each intelligent agent according to a preset rule and the transaction data input by each intelligent agent.
The third intelligent agent calls a corresponding contract function according to the transaction result, and the contract function comprises the following steps:
the third intelligent agent detects whether the spectrum owner corresponding to the first intelligent agent releases the spectrum according to the spectrum transaction instruction;
if yes, calling a contract function corresponding to successful transaction;
if not, the contract function corresponding to the transaction failure is called.
The radio monitoring party may detect whether the spectrum owning party corresponding to the first intelligent agent releases the spectrum according to the spectrum transaction instruction, that is, whether the spectrum resource with the agreed bandwidth is released according to the spectrum release time agreed with the second intelligent agent, if so, the third intelligent agent invokes a contract function corresponding to successful transaction, and if not, the third intelligent agent invokes a contract function corresponding to failed transaction. The contract function corresponding to the successful transaction and the contract function corresponding to the failed transaction are preset and respectively correspond to different token amount adjusting rules, for example, when the transaction is successful, a token amount corresponding to the frequency spectrum transaction price, a token amount corresponding to the frequency spectrum monitoring fee value and a token amount corresponding to the financial guarantee fee value are transferred from the account of the second intelligent agent, a token amount corresponding to the guarantee fee value is transferred into the account of the second intelligent agent, a frequency spectrum transaction price in the transaction data is transferred into the account of the first intelligent agent, and the like; and when the transaction fails, transmitting the token amount corresponding to the guarantee fund value from the account of the first intelligent agent, and the like. The preset rules for adjusting the amount of the token after the transaction is finished can be set according to practical application, and are not exemplified herein.
After the intelligent contracts adjust the token amount in the accounts of the intelligent agents according to the transaction data, the intelligent contracts comprise the following steps:
the accounts of the first intelligent agent, the second intelligent agent and the third intelligent agent send the address of the intelligent contract to the fourth intelligent agent, so that the frequency spectrum transaction participant corresponding to the fourth intelligent agent performs token clearing.
After the transaction is finished, the accounts of the first intelligent agent, the second intelligent agent and the third intelligent agent send the address of the intelligent contract to the fourth intelligent agent, and the spectrum transaction participants (financial parties) corresponding to the fourth intelligent agent can determine the authenticity of the balance of the account according to the address of the intelligent contract, remit money of tokens in each account through a bank and convert the remittance into funds, so that the transaction settlement is finished.
In the above-mentioned spectrum transaction process performed on the block chain, the block packer of the block chain is the server, that is, the server performs block packing as a trusted third party, and the consensus before block packing only needs to be achieved by an intelligent agent of a participant of the spectrum transaction, so that the consensus time in this embodiment is very short, and millisecond-level uplink can be implemented.
In summary, in the method, the intelligent agents of the buyer and the seller of the spectrum transaction firstly determine target transaction data through a game, so that the maximum benefit of both parties is ensured, a block chain which only needs the intelligent agents of the spectrum transaction participants to achieve consensus is constructed, the secure transaction is realized by using the characteristics of the block chain, and meanwhile, since only the spectrum transaction participants need to achieve consensus, the overall network consensus is not needed, the consensus time can be greatly reduced, millisecond-level uplink is realized, and the real-time requirement of the spectrum transaction is met.
