Simultaneously, combining the characteristics and advantages of 5G networks with those of low-Earth orbit satellites, international standardization organizations have also conducted research on the integration of 5G and satellite Internet, defining a ubiquitous integrated mobile communication network encompassing air, space, land, and sea using "5G + satellite network," extending to the future development trend of 6G networks. It is evident that the integrated development of satellite networks and 5G, and the deep application of 6G, are important directions for future communication development and have gradually become a focus of attention in the communication network industry.

[0068] In one embodiment, processor 101 can be used to invoke a blockchain-based satellite network frequency coordination program stored in memory 102 and perform the following operations:

[0069] If the first interference simulation result and the second interference simulation result are inconsistent, then the third interference simulation result shall be determined based on the declared satellite network data;

[0070] If the third interference simulation result is consistent with the first interference simulation result, then the first interference simulation result is determined to meet the preset conditions, and a reward is obtained. The satellite network data is packaged into blocks, and the blockchain is updated according to the blocks.

[0071] In one embodiment, processor 101 can be used to invoke a blockchain-based satellite network frequency coordination program stored in memory 102 and perform the following operations:

[0084] If no verification node has a frequency overlap with the target node, the satellite network data is packaged into blocks, and the blockchain is updated based on the blocks.

[0085] Based on the hardware architecture of the blockchain-based satellite network frequency coordination device described above, an embodiment of the blockchain-based satellite network frequency coordination method of the present invention is proposed.

[0086] Reference Figure 2 , Figure 2 This is a first embodiment of the blockchain-based satellite network frequency coordination method of the present invention, which includes the following steps:

[0087] Step S10: Receive satellite network data broadcast from the target node.

[0088] Optionally, the target node is the satellite network unit that is declaring satellite information, and the current verification node is the satellite network unit. Setting the satellite network unit as the verification node of the blockchain makes the frequency coordination of satellite network data public, transparent, secure, and trustworthy. Notably, this is a public blockchain, which has no central node. Figure 3 As shown, 'a' represents a node, and 'b' represents the blockchain corresponding to 'a'. Each node is equal and stores the entire network's database; that is, each node has the current point in time. A database of satellite frequency orbits for all satellite network units, i.e., a blockchain. (For example...) Figure 4 As shown, each block in the blockchain mainly consists of a block header and a block body. The block header contains information such as the hash value of the previous block, the hash value of the current block, the mining difficulty bits, the proof-of-work random number, and the timestamp. The block body mainly contains frequency coordination transaction information for satellite network data.

[0089] Optionally, the system receives satellite network data broadcast from the target node. This satellite network data mainly includes information such as the satellite's frequency, trajectory, project background, and intended use.

[0090] Step S20: If the declared satellite network data overlaps with the current verification node in frequency, then the priority of the target node and the current verification node is determined.

[0091] Optionally, the target node Preparing to submit new satellite network data, it It continuously broadcasts to all other verification nodes in the network. Other verification nodes receive the target node's message. The broadcast information, i.e., the target node The provided new satellite network data allows other verification nodes to check whether their own satellite network frequencies match those of the target node. There is overlap in the frequency of the applications.

[0092] Optionally, if no verification node and target node exist... The declared satellite network data frequencies overlap, and the target nodes... Satellite network data is packaged into blocks, and the blockchain is updated based on the blocks. The remaining validator nodes update their own validator nodes' blockchains according to the newly generated blockchain.

[0093] Optionally, if the current verification node Satellite network data and target nodes If the declared satellite network data have overlapping frequencies, the priority of the target node and the current verification node will be determined.

[0094] Optionally, if the target node Network status takes precedence over verification nodes That is, the current verification node Its priority is lower than that of the target node. Then verify the node and target node Frequency coordination is required, and verification nodes are needed. As the coordinator, the target node The party being coordinated. Among them, transaction T B→A To represent two verification nodes and The frequency coordination process ensures that every transaction on the blockchain is visible to all other validating nodes.

[0095] Optionally, if the verification node Network position takes precedence over target node That is, the current verification node Its priority is higher than that of the target node. Then the target node and verification nodes Frequency coordination is required, and the target node... As the coordinator, verify the node. The party being coordinated. Among them, transaction T is used. A→B To represent two nodes and In the frequency coordination process, every transaction on the blockchain is visible to all nodes. Optionally, if the current verification node has a higher priority than the target node, it receives the first interference simulation result broadcast by the target node, which is generated by the target node based on satellite network data.

[0096] Step S30: If the priority of the current verification node is lower than that of the target node, a first interference simulation result is generated based on the satellite network data, and the first interference simulation result is broadcast to the blockchain, so that after the first simulation interference result meets the preset conditions, the current verification node performs frequency coordination based on the first simulation interference result.

[0097] Optionally, if the current verification node Its priority is lower than that of the target node. Then the current verification node according to Time target node Interference simulation calculations are performed on the broadcast satellite network data to obtain a first interference simulation result. This result includes simulation parameters for both the coordinating and coordinated parties, screenshots of the interference simulation results, and data analysis. After the first simulation interference result meets preset conditions, the current verification node performs frequency coordination based on these results. Optionally, the preset conditions include other verification nodes determining a second simulation interference result based on the target node's satellite network data and the current verification node's network data, ensuring consistency between the first and second simulation interference results.

[0098] Optionally, the useful signal power, noise power, and interference power of the target node are determined based on satellite network data; the carrier-to-noise power ratio of the target node is determined based on the useful signal power and noise power; and a first interference simulation result is determined based on the carrier-to-noise power ratio and interference power. For example, a verification node... according to Time target node Interference simulation calculations are performed on the broadcast satellite network data, and the first interference simulation results are produced. The target node is simulated and calculated. Useful signal power at the disturbed receiver Interference power and noise power Then the carrier noise power ratio is calculated. target node The disturbed receiver needs to satisfy the following formula:

[0099]

[0100] Among them, (S / N) th and (I) th Interference protection standard limits.

[0101] Optionally, when the carrier-to-noise power ratio is greater than a preset first threshold and the interference power is greater than a second threshold, it is determined that the target node has frequency interference; the interference duration of the target node with frequency interference and the total operating time of the target node are determined; the interference simulation result is determined based on the proportion of the interference duration to the total operating time. For example, the interference duration exceeding the interference protection standard is used as the numerator, and the total operating time of the interfered link is used as the denominator. For instance, if the proportion of the duration where the power of a single-input interference signal exceeds -150dBW per 10MHz bandwidth within the overlapping frequency does not exceed 20%, or the proportion of the duration where the power exceeds -133dBW per 10MHz bandwidth does not exceed 0.005%, then it is considered... Satellite networks will not affect The first interference simulation results of harmful interference generated by satellite networks, verifying the node. The first interference simulation result is broadcast to all other verification nodes. Optionally, the calculation methods for the first interference simulation result, the second interference simulation result, and the third interference simulation result can all be as described above.

[0102] In this embodiment, the system receives satellite network data broadcast from a target node. If the broadcast satellite network data overlaps in frequency with the current verification node, the priorities of the target node and the current verification node are determined. If the priority of the current verification node is lower than that of the target node, a first interference simulation result is generated based on the satellite network data. When the priority of the target node is higher than that of the verification node, the satellite network data broadcast by the target node is simulated through nodes on the blockchain to generate the first interference simulation result, thereby improving the efficiency and accuracy of frequency coordination of the broadcast satellite network data.

[0103] Reference Figure 5 , Figure 5 This is a second embodiment of the blockchain-based satellite network frequency coordination method of the present invention. Based on the first embodiment, after step S10, it further includes:

[0104] Step S40: If the target node and the current verification node do not have frequency overlap and the first interference simulation result is received, then a second interference simulation result is generated based on the declared satellite network data, and the second interference simulation result is broadcast to the blockchain.

[0105] Optionally, the remaining verification nodes in the entire network receive verification from the verification node. Based on the first disturbance simulation result provided, all other verification nodes begin to... Node verification at all times Network parameters and Time target node The broadcast satellite network parameters are simulated to obtain the second interference simulation result, which is used to verify the nodes. The accuracy of the first interference simulation result provided. If one of the remaining verification nodes does not have frequency overlap with the target node and receives the first interference simulation result, then it generates a second interference simulation result based on the declared satellite network data and broadcasts it. For example, if the verification node... The first simulation of the second interference was obtained based on the submitted satellite network data, and the node was verified. The simulation results of the second interference will be published to the entire network, that is, the simulation results of the second interference will be broadcast to the blockchain.

[0106] Optionally, if the target node and the current verification node do not have frequency overlap, and the first interference simulation result and the second interference simulation result are received, then the first interference simulation result and the second interference simulation result are compared. For example, for the verification node... The second interference simulation results were confirmed and compared with the verification nodes. First interference simulation results and verification nodes Whether the simulation results of the second interference are consistent.

[0107] Optionally, if the first interference simulation result and the second interference simulation result are consistent, then the first interference simulation result is determined to meet a preset condition, and a reward is given to the verification node corresponding to the second simulation result. The verification node corresponding to the second simulation result packages the satellite network data into blocks and updates the blockchain according to the blocks. For example, the verification node... First interference simulation results and verification results The simulation results for the second interference are consistent. Once other nodes are confirmed to be correct, [further action will be taken]. A certain reward.

[0108] Optionally, if the first interference simulation result and the second interference simulation result are inconsistent, a third interference simulation result is determined based on the declared satellite network data; if the third interference simulation result is consistent with the first interference simulation result, the first interference simulation result is determined to meet preset conditions, and a reward is obtained. The satellite network data is packaged into a block, and the blockchain is updated based on the block; if the third interference simulation result is inconsistent with the first interference simulation result, the first interference simulation result is determined to be incorrect, so that the verification node corresponding to the first simulation result re-determines the simulation result. For example, if the verification node... First interference simulation results and verification nodes The simulation results for the second interference were inconsistent, so other verification nodes continued simulation calculations until a new verification node was found. The third interference simulation result is calculated and broadcast before other verification nodes, and the remaining verification nodes compare the results with the original verification nodes. The third interference simulation results, and the verification node First interference simulation results and verification nodes The consistency of the second interference simulation results, if the verification node The third interference simulation results and verification nodes The simulation results for the first disturbance are consistent. After other nodes are confirmed to be correct, the verification node will be provided. Certain rewards, verification nodes Satellite network data is packaged into blocks, and the blockchain is updated based on these blocks. If the validating node... The third interference simulation results and verification nodes The second interference simulation results are consistent, then the verification node The first interference simulation report has problems; the coordinator The simulation report needs to be reviewed and updated before being broadcast to other nodes. The validator node that receives the reward is responsible for transmitting the transaction T. A→B The blocks are packaged into blocks and then uploaded to the blockchain. Other nodes update their own blockchains based on the blockchain of the validating node that received the reward.

[0109] In this embodiment, if the target node and the current verification node do not have frequency overlap and the first interference simulation result is received, a second interference simulation result is generated based on the declared satellite network data and broadcast. After obtaining the first interference simulation result by simulating the declared network satellite data through the verification node, the second interference simulation result is determined to verify the first interference simulation result, thereby improving the accuracy of the first interference simulation result and enhancing the efficiency and accuracy of satellite network data frequency coordination.

[0114] Optionally, the target node is the satellite network unit that is declaring satellite information, and the current verification node is the satellite network unit. Setting the satellite network unit as the verification node of the blockchain makes the frequency coordination of satellite network data public, transparent, secure, and trustworthy. Notably, this is a public blockchain, which has no central node. Figure 3 As shown, 'a' represents a node, and 'b' represents the blockchain corresponding to 'a'. Each node is equal and stores the entire network's database; that is, each node has the current point in time.

The block body mainly contains frequency coordination transaction information for satellite network data.

[0115] When the target node receives a new request for satellite network data, it determines the satellite network data to be declared and broadcasts it.

Other verification nodes receive the target node's message. The broadcast information, i.e., the target node The provided new satellite network data allows other verification nodes to check whether their own satellite network frequencies match those of the target node. There is overlap in the frequency of the applications.

[0117] Optionally, if no verification node and target node exist... The declared satellite network data frequencies overlap, and the target nodes... Satellite network data is packaged into blocks, and the blockchain is updated based on the blocks. The remaining validator nodes update their own validator nodes' blockchains according to the newly generated blockchain.

[0118] Optionally, if the verification node Satellite network data and target nodes If the declared satellite network data have overlapping frequencies, the priority of the target node and the current verification node will be determined.
