Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The mobile communication method provided by the embodiment of the invention is to arrange the base station, the terminal and the customer information system in the same block chain network, namely the base station, the terminal and the customer information system are all one node in the block chain network. The base station is used as a service node of the block chain to access the block chain and provide access service for the terminal.
In the block chain network, the base station, the terminal and the customer information system belong to the same operator, and in the created block of the block chain, the block chain identification, the public key and other information of the terminal, the base station and the customer information system node are stored and are used as the starting node of the block chain to manage the block chain.
Before implementing the mobile communication method provided in this embodiment, the terminal registers in a non-blockchain manner (for example, the terminal is in a business hall of the operator) at the operator to which the client information system belongs, or otherwise obtains registration information of the operator, and after the terminal registers in the client information system, the client information system obtains an identification code of the terminal and an operator service password, where the terminal identification code may be, but is not limited to, a Universal Subscriber Identity Module (USIM) and a Subscriber Identity Module (SIM).
The embodiment provides a mobile communication method based on a block chain network, which is applied to a terminal. As shown in fig. 1, the mobile communication method includes the steps of:
in step S101, a random number provided from the customer information system is received.
Where the random number is a string of numbers, such as 12345: provided by the customer information. The length of the digit string and the arrangement of the digits may be predetermined or random.
In step S102, a first encryption result is obtained according to a predetermined algorithm using the terminal identification code, the operator service password, and the random number.
The terminal Identification code is not limited to a Subscriber Identity Module (SIM) or a Universal Subscriber Identity Module (USIM), and may also be referred to as a mobile phone number, i.e., an Identification number for distinguishing the terminal Identity.
The operator service password is a password that the terminal assigns to the terminal after the registration of the customer information system, or a password that is set when the terminal registers in the customer information system provided by the operator.
It should be noted that the agreed algorithm is an algorithm agreed by the terminal and the client information system, the algorithm is an encryption algorithm, and both existing and future encryption algorithms can be used in the present embodiment.
In one embodiment, the customer information system sends the customer information system to the terminal in a short message mode through a mobile switching network.
In step S103, the private key of the terminal is used to sign the terminal block chain identifier, the terminal identification code, the base station expected to be accessed, the used frequency band, and the first encryption result, so as to obtain a second terminal broadcast message.
It should be noted that the base station and the frequency band to be used, which are desired to be accessed, are selected by the terminal according to the spectrum provided by the base station. Specifically, the terminal searches base station information in a physical address range by using the baseband processor module, searches corresponding base station broadcast messages in a block chain network by using the block chain identification of each base station, and selects a base station to be accessed and a frequency band to be used according to frequency spectrums and use prices of different base stations.
It should be noted that, since each base station has a certain coverage, in order to ensure no communication dead space, a partial area is often covered by a plurality of base stations. Therefore, when a terminal searches for a base station, there are often cases where a plurality of base stations are searched for. When the terminal searches for a base station, it only needs to select a frequency band expected to be used from the frequency spectrum provided by the base station according to the use condition and the use price of the base station. When the terminal searches for a plurality of base stations, the base station expected to be accessed can be selected according to the use condition and the use price of the base station, and the frequency band expected to be used can also be selected.
The frequency spectrum provided by each base station is divided into different frequency bands, and the use conditions and the prices of the frequency spectrums in the different frequency bands are different. Therefore, each base station detects the use condition of the own frequency spectrum in real time, predicts the idle time of the frequency spectrum use of different frequency bands according to historical data, for example, predicts the idle time of the frequency spectrum use of different frequency bands in the current time period according to the historical use data of the frequency spectrum of different frequency bands, and calculates the use price of the frequency spectrum of different frequency bands in unit time length.
In one embodiment, each base station obtains a base station broadcast message after signing the idle time of the spectrum use of different frequency bands and the use price of unit time length by using a private key of the base station according to a certain time interval, and then broadcasts the base station broadcast message in a block chain network.
A terminal acquires a base station broadcast message from a block chain network; and selecting a base station expected to be accessed and a used frequency band according to the base station broadcast message. The user can select the accessed base station and the used frequency band according to the actual situation, for example, the user selects the frequency band with small power consumption according to the residual electric quantity of the terminal, and selects the frequency band according to the required downloading speed. Of course, when the user selects the base station desired to be accessed and the used frequency band through the terminal, the user needs to combine the use price and the use state of different frequency bands, such as whether the user is idle or not.
And the terminal selects the base station and the use frequency band which are expected to be accessed, and signs the terminal block chain identification, the terminal identification code, the base station and the use frequency band which are expected to be accessed and the first encryption result by using a private key after the first encryption result is calculated, so that a second terminal broadcast message is obtained.
In step S104, a second terminal broadcast message is broadcast in the blockchain network.
The second terminal broadcast message comprises a terminal block chain identifier, a terminal identification code, a base station expected to be accessed, a use frequency band and a first encryption result, and is signed by a terminal private key, and then the second terminal broadcast message is broadcast in a block chain network.
In step S105, the base station and the used frequency band provided by the base station are accessed in response to the grant message fed back by the base station.
After obtaining the customer information system broadcast message and the terminal broadcast message in the block chain network, the base station needs to verify the two broadcast messages, and after verification, feeds back the use approval message to the terminal and provides the use frequency band for the terminal. Specifically, after receiving the broadcast message of the client information system, the base station queries the block chain account book by using the block chain identifier of the client information system to obtain the public key of the client information system, and then performs first verification on the private key signature of the client information system in the broadcast message of the client information system by using the public key of the client information system. And after receiving the terminal broadcast message, the base station queries a block chain account book by using the block chain identifier of the terminal to obtain a terminal public key, then performs second verification on the terminal private key signature in the terminal broadcast message terminal by using the terminal public key, and if the first verification and the second verification are both passed, the base station agrees that the terminal uses the provided use frequency band. And if one of the first verification and the second verification is not passed, the base station refuses the terminal to use the use frequency band provided by the terminal.
Because the broadcast message of the client information system is the message broadcast in the block chain network after the client information system verifies the terminal identity, the base station verifies the identity of the terminal after verifying the broadcast message of the client information system through the public key, thereby avoiding the identity of the terminal from being falsely used and providing the security of the terminal.
The second embodiment of the present invention is basically the same as the first embodiment, except that the terminal broadcast message broadcasted by the terminal in the block chain network contains the base station that the terminal desires to access and the frequency band used by the terminal. The following description focuses on the differences.
As shown in fig. 2, a second implementation provides a method for mobile communication based on a blockchain network, including:
in step S201, a base station broadcast message is obtained from a blockchain network.
The base station broadcast message is a message broadcast by the base station in the blockchain network, and includes the idle condition of the frequency spectrums of different frequency bands in the current time period, frequency spectrum information and use price. The usage price refers to the price of the unit time length of the access frequency spectrum, and the prices of the unit time lengths of the frequency spectrums in different frequency bands can be different or the same. When the prices of the spectrum in different frequency bands are different in unit time length, the base station broadcast message should include the use prices of the different frequency bands. The spectrum message refers to a used spectrum that can be provided by the base station, and is generally composed of spectrums of different frequency bands, that is, the base station provides spectrums of a plurality of frequency bands.
In one embodiment, the base station detects the actual usage of the frequency spectrum in real time, and predicts the idle time of the frequency spectrum usage of different frequency bands according to historical data, for example, predicts the idle time of the frequency spectrum usage of different frequency bands in the current time period according to the historical usage data of the frequency spectrum of different frequency bands, and calculates the usage price of the frequency spectrum of different frequency bands in unit time length.
The base station broadcasts the base station broadcast message in the block chain network according to a certain time interval, and before broadcasting, the base station signs the idle time of the frequency spectrum use of different frequency bands and the use price of unit duration by using the private key of the base station.
In one embodiment, the terminal searches for the base station information in the physical address range by using a baseband processor module, and the baseband processor module can adopt any one of 2G, 3G, 4G and 5G.
In step S202, a base station desired to be accessed and a frequency band to be used are selected according to the base station broadcast message.
In one embodiment, the terminal searches for a corresponding base station broadcast message in a blockchain network by using the blockchain identifier of each base station, and then selects a base station to be accessed and a frequency band to be used according to frequency spectrums and use prices of different base stations. For example, the user may select a frequency band with a small power consumption according to the remaining power of the terminal, or select a frequency band with a high transmission rate according to a required download speed.
In step S203, a first terminal broadcast message is broadcast in the blockchain network.
The first terminal broadcast message comprises a terminal block chain identifier, a terminal identification code, a base station expected to be accessed and a use frequency band.
In one embodiment, the terminal signs the first terminal broadcast message with its own private key and then broadcasts in the blockchain network.
In step S204, a random number provided from the customer information system is received.
The random number is provided by the customer information system in short message mode through the mobile switching network.
In one embodiment, after receiving a first terminal broadcast message, a customer information system queries a block chain account book by using a block chain identifier of a terminal to obtain a public key of the terminal, verifies a private key signature in the first terminal broadcast message by using the public key of the terminal, and sends a random number to the terminal according to a terminal identification code in the first terminal broadcast message if the verification is passed.
In step S205, a first encryption result is obtained according to a predetermined algorithm using the terminal identification code, the operator service password, and the random number.
In step S206, the private key of the terminal is used to sign the terminal block chain identifier, the terminal identification code, the base station expected to be accessed, the used frequency band, and the first encryption result, so as to obtain a second terminal broadcast message.
In step S207, the base station and the used frequency band provided by the base station are accessed in response to the grant message fed back by the base station.
Steps S205 to S207 in this embodiment are the same as steps S103 to S105 in the first embodiment, and are not repeated herein.
In the mobile communication method provided by the embodiment, the terminal selects a base station and a frequency band which are expected to be accessed according to frequency spectrum information and use price provided by the base station, and generates a first encryption result by using a random number provided by a client information system, the client information system broadcasts a client information system broadcast message after the identity of the terminal is verified by using the first encryption result, the identity of the terminal is verified by using the random number provided by the client information system, and the benefit of a user and the base station is ensured by using the identity verification and information tracing of a block chain; and the random number is provided to the terminal by the client information system in a short message mode, so that even if a hacker accumulates massive first encryption results, the password of the operator of the client cannot be guessed, the security of the terminal is further improved, and the benefit of the user is guaranteed.
A third embodiment of the present invention provides a mobile communication method based on a blockchain network, which is applied to a customer information system. As shown in fig. 3, the mobile communication method based on the block chain network includes the following steps:
in step S301, a random number is transmitted to the terminal.
The random number is provided by the customer information system in short message mode through the mobile switching network.
In one embodiment, the client information system sends the random number to the terminal after receiving the first terminal broadcast message. Specifically, after the client information system receives the first terminal broadcast message, the block chain account book is inquired by using the block chain identifier of the terminal to obtain the public key of the terminal, the private key signature in the first terminal broadcast message is verified by using the terminal public key, and if the verification is passed, the random number is sent to the terminal according to the terminal identification code in the first terminal broadcast message.
In step S302, a second terminal broadcast message is received in the blockchain network.
The second terminal broadcast message is a message broadcast by the terminal in the blockchain network, and the second terminal broadcast message includes a terminal blockchain identifier, a terminal identification code, a base station expected to be accessed, a used frequency band and a first encryption result.
In one embodiment, the first encryption result is derived according to a contracted algorithm using the terminal identification code, the operator service password, and the random number.

Each base station detects the use condition of the base station, predicts the idle time of the spectrum use of different frequency bands according to historical data, for example, predicts the idle time of the spectrum use of different frequency bands in the current time period according to the historical use data of the spectrum of different frequency bands, calculates the use price of unit time length of the spectrum of different frequency bands, and then broadcasts a base station broadcast message in a block chain network. The base station broadcast message comprises a base station number, the idle condition of frequency spectrums of different frequency bands and the use price.
In one embodiment, each base station obtains a base station broadcast message after signing the idle time of the spectrum use of different frequency bands and the use price of unit time length by using a private key of the base station according to a certain time interval, and then broadcasts the base station broadcast message in a block chain network.
In step S702, the terminal searches for a base station broadcast message, and selects a base station desired to be accessed and a frequency band to be used according to the base station broadcast message.
The terminal searches the base station information within the physical address distance range, extracts the block chain identification according to the searched base station information, and then searches the base station broadcast message corresponding to the block chain identification in the block chain network. For example, when the terminal searches for two base stations, namely, a base station a and a base station B, within the range of the physical address distance, a blockchain account book is searched in a blockchain network according to blockchain identifiers of the base station a and the base station B to obtain a base station public key, and then a base station private key signature in a base station broadcast message is verified by using the corresponding base station public key, if the verification is passed, it is indicated that the base station broadcast message is sent by a real base station. The terminal obtains the idle condition and the use price of the current time period of the frequency spectrum of different frequency bands of the base station from the broadcast message of the base station, and then selects the base station expected to be accessed and the use frequency band from the idle condition and the use price. For example, the terminal selects base station a to provide network service for the terminal, and may select a certain video frequency band determined in base station a.

Of course, when the user selects the base station desired to be accessed and the used frequency band through the terminal, the user needs to combine the use price and the use state of different frequency bands.
In step S703, the terminal broadcasts a first terminal broadcast message in the blockchain network.
The terminal obtains a first terminal broadcast message from the terminal block chain identifier, the terminal identification code, the base station expected to be accessed and the use frequency band according to the base station expected to be accessed and the use frequency band obtained in the step S702, then signs the first terminal broadcast message by using the terminal private key, and broadcasts in the block chain network.

It should be noted that, the client information system obtains the first terminal broadcast message from the blockchain network, queries the blockchain ledger by using the blockchain identifier of the first terminal broadcast message, obtains the terminal public key, and verifies the private key signature in the first terminal broadcast message by using the terminal public key. And if the verification is passed, sending a random number to the terminal.

In step S705, the terminal obtains a second terminal broadcast message according to the random number.
After the terminal receives the random number of the customer information system, a first encryption result is obtained by using the terminal identification code, the operator customer service password and the random number according to an agreed algorithm. Then, forming second terminal broadcast information by the terminal block chain identification, the terminal identification code, the operator customer service password, the random number, the base station expected to be accessed and the use frequency band, signing the second terminal broadcast information by using a private key of the terminal, and then broadcasting the second terminal broadcast information in the block chain network.
In step S706, the client information system verifies the identity of the terminal.
And after receiving the second terminal broadcast message in the blockchain network, the client information system inquires a blockchain account book according to the blockchain identifier of the terminal to obtain the public key of the terminal. And then, verifying the private key signature of the second terminal broadcast message by using the terminal public key, if the private key signature passes the verification, inquiring an operator customer service password and a random number reserved in a customer information system according to a terminal identification code in the second broadcast message, and then calculating a second encryption result according to an agreed algorithm by using the terminal identification code operator customer service password and the random number. And the client information system compares the first verification result with the second encryption result, and if the first verification result is consistent with the second encryption result, the terminal identity is verified. The client information system signs the broadcast message of the client information system by using a private key and broadcasts in the block chain network to indicate that the identity of the terminal is real and credible. The client information system broadcast message includes information such as a client information system blockchain identifier, a terminal identification code, and the like.
In step S707, the base station verifies the second terminal broadcast message and the customer information system broadcast message, and provides the terminal with a use frequency band desired by the terminal.
After obtaining the customer information system broadcast message and the terminal broadcast message in the block chain network, the base station needs to verify the two broadcast messages, and after verification, feeds back the use approval message to the terminal and provides the use frequency band for the terminal. Specifically, after receiving the broadcast message of the client information system, the base station queries the block chain account book by using the block chain identifier of the client information system to obtain the public key of the client information system, and then performs first verification on the private key signature of the client information system in the broadcast message of the client information system by using the public key of the client information system. And after receiving the terminal broadcast message, the base station queries a block chain account book by using the block chain identifier of the terminal to obtain a terminal public key, then performs second verification on the terminal private key signature in the terminal broadcast message terminal by using the terminal public key, and if the first verification and the second verification are both passed, the base station agrees that the terminal uses the provided use frequency band. And if one of the first verification and the second verification is not passed, the base station refuses the terminal to use the use frequency band provided by the terminal.
In step S708, after receiving the message fed back by the base station, the terminal accesses the desired base station and uses the used frequency band provided by the base station.
