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 preferred embodiment of the 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 with the operator to which the customer information system belongs in a non-block chain manner (for example, the terminal is in a business hall of the operator), or otherwise obtains registration information of the operator, that is, the customer information system owns an identification code of the terminal and an operator service password, where the terminal identification code may be, but is not limited to, a card number of a universal subscriber identity card (USIM) of the terminal.
The embodiment provides a mobile communication method 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 is obtained from the block chain network.
The customer information system broadcasts a random number, which is a string of numbers, in the blockchain network at regular intervals. The time interval of broadcasting can be set arbitrarily, and the length of the digit string can be set arbitrarily, such as 12345.
It should be noted that, before broadcasting the random number in the blockchain network, the client information system signs the random number with its own private key, and then broadcasts the random number in the blockchain network.
Since the client information system broadcasts the random number in the blockchain network at regular intervals, and the random number obtained by the terminal from the blockchain network is the random number of the client information system closest to the current time. For convenience of description, the current random number is hereinafter simply referred to as a random number.
In one embodiment, the step of the terminal obtaining the random number from the block chain network comprises: obtaining a public key of the client information system from a block chain account book according to a block chain identifier of the client information system in a block chain network; verifying the private key signature of the broadcast message of the client information system by using the public key of the client information system; upon verification, the random number is obtained from the customer information system broadcast message.
In step S102, a first encryption result is calculated by a preset 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 assigned to the terminal by the client information system, that is, the password is set when the terminal is registered in the client information system provided by the operator.
It should be noted that the preset 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, a terminal firstly queries a blockchain network in the blockchain network according to a blockchain identifier of a client information system to obtain a public key of the client information system, verifies a private key signature of the client information system by using the public key, obtains a random number from information broadcast by the client information system if the verification is passed, and then calculates a first encryption result by using a terminal identification code, an operator customer service password and the random number through a preset algorithm.
In step S103, the terminal broadcast information is broadcast in the block chain network.
The terminal broadcast information comprises a first encryption result, a terminal identification code and a terminal block chain identifier. The terminal block chain identifier is used for identifying the terminal broadcast information in the block chain network, that is, the base station can judge whether the broadcast message obtained from the block chain network is a message sent by the terminal or a message sent by a client information system by using the terminal block chain identifier.
In one embodiment, the terminal signs the first encryption result, the terminal identification code and the terminal blockchain identifier in the blockchain network by using a private key of the terminal to obtain a terminal broadcast message, and then broadcasts the terminal broadcast message in the blockchain network.
In step S104, the base station and the use frequency band provided by the base station are used in response to the grant message of the base station.
It should be noted that the base station may actively provide the used frequency band for the terminal, and may also provide the used frequency band according to the request of the terminal. The terminal is verified whether the base station actively or passively provides the use frequency band, namely, the terminal broadcast information is verified by utilizing the broadcast information of the customer information system. Specifically, after receiving the broadcast message of the customer information system, the base station queries the block chain account book by using the block chain identifier of the customer information system to obtain the public key of the customer information system, and performs first verification on the private key signature of the customer information system in the broadcast message of the customer information system by using the public key of the customer 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.
It should be further noted that the client information system broadcasts the client information system broadcast message in the blockchain network after verifying the identity of the terminal by using the first encryption result. Specifically, after receiving the terminal broadcast information, the client information system queries a blockchain account book according to a blockchain identifier of the terminal to obtain a terminal public key, then verifies a private key signature of the terminal broadcast information by using the terminal public key, if the verification is passed, searches an operator customer service password and a random number reserved in the client information system by the terminal through a terminal identification code in the terminal broadcast information, then calculates a second encryption result through a preset algorithm (the same algorithm as that in step S102) by using the terminal identification code, the operator customer service password and the random number, compares the first encryption result with the second encryption result, and if the first encryption result is consistent with the second encryption result, passes the terminal identity verification, and the terminal identity has no problem. The client information system utilizes the private key signature of the client information system and broadcasts the broadcast message of the client information system in the block chain network to confirm the identity of the terminal to be real and credible.
In the mobile communication method provided by the embodiment, the terminal calculates the first encryption result by using the terminal identification code, the operator customer service password and the random number provided by the customer information system, the customer information system broadcasts the customer information system in the blockchain network after the identity of the terminal is verified, the base station sends the use approval message after verifying the terminal broadcast message by using the customer information system broadcast message, and the terminal uses the use frequency band provided by the base station.
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, the mobile communication method according to the second embodiment includes:
step S201, selecting an accessed base station and a used frequency band.
When accessing a base station, a terminal first searches for the base station, and then determines which base station to access and which frequency band to use. However, each base station has a certain coverage area, and in order to ensure that there is no dead angle for communication, a part of the area is covered by a plurality of base stations. Therefore, when a terminal searches for a base station, it is often the case that one or more base stations are searched.
In addition, the frequency spectrum provided by each base station is divided into different frequency bands, and the use conditions of the frequency spectrum of 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.
Each base station signs the idle time used by the frequency spectrums of different frequency bands and the use price of unit time length by using a private key according to a certain time interval to obtain a base station broadcast message, and then broadcasts the base station broadcast message in a block chain network.
In one embodiment, a base station broadcast message is obtained from a blockchain 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 can also select the frequency band according to the downloading speed.
It should be noted that, when the terminal obtains a plurality of base stations through searching, the terminal selects a base station desired to be accessed and selects a frequency band provided by the base station through a base station broadcast message provided by each base station. When the terminal searches for only one base station, it can only select the frequency band provided by the base station.
In step S202, a random number is obtained from the blockchain network.
In step S203, a first encryption result is calculated by a preset algorithm using the terminal identification code, the operator service password, and the random number.
Step S202 and step S203 are the same as step S101 and step S102 in the first embodiment, and are not described again.
In step S204, the terminal broadcast information is broadcast in the blockchain network.
The terminal broadcast information comprises a first encryption result, a terminal identification code, a terminal block chain identifier, a base station which the terminal expects to access and a use frequency band.
In step S205, the base station and the use frequency band provided by the base station are used in response to the grant message from the base station.
In one embodiment, after receiving the broadcast message of the customer information system, the base station queries the blockchain ledger by using the blockchain identifier of the customer information system to obtain the public key of the customer information system, and performs a first verification on the private key signature of the customer information system in the broadcast message of the customer information system by using the public key of the customer 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.
And after the base station passes the first verification and the second verification, providing service for the terminal according to the base station expected to be accessed and the use frequency band in the terminal broadcast message.
It should be noted that, the identity of the client information system is verified by using the first encryption result, which is the same as the first embodiment and is not described herein again.
In the mobile communication method provided by this embodiment, after the terminal searches for the base station information, the terminal acquires the base station broadcast message in the blockchain network according to the base station information, then selects the accessed base station and the used frequency band according to the base station broadcast message, and obtains the first encryption result by using the random number, the client information system broadcasts the client information system in the blockchain network after authenticating the identity of the terminal, the base station sends out the usage agreement message after authenticating the terminal broadcast message by using the client information system broadcast message, and provides the terminal with the expected usage frequency band, so that the terminal can select the accessed base station and frequency band by itself, user experience is improved, the security of the base station and the terminal is provided by using the random number, and the security and benefit of both the base station and the terminal are ensured.
A third embodiment of the present invention provides a mobile communication method applied to a base station. As shown in fig. 3, the mobile communication method includes the steps of:
in step S301, a terminal broadcast message is obtained from a blockchain network.
The terminal broadcast message comprises a first encryption result, a terminal identification code and a terminal block chain identifier, wherein the first encryption result is calculated by using the terminal identification code, an operator customer service password and a random number through a preset algorithm, and the random number is broadcasted in a block chain network by a customer information system. The generation method of the terminal broadcast message is the same as step S101 in the first embodiment, and is not described herein again.
In step S302, a customer information system broadcast message is obtained from the blockchain network.
The client information system broadcast message is a message broadcast in the blockchain network after the client information system verifies the identity of the terminal by using the first encryption result.
Specifically, after receiving the terminal broadcast information, the client information system queries a blockchain account book according to a blockchain identifier of the terminal to obtain a terminal public key, then verifies a private key signature of the terminal broadcast information by using the terminal public key, if the verification is passed, searches an operator customer service password and a random number reserved in the client information system by the terminal through a terminal identification code in the terminal broadcast information, then calculates a second encryption result through a preset algorithm (the same algorithm as that in step S102) by using the terminal identification code, the operator customer service password and the random number, compares the first encryption result with the second encryption result, and if the first encryption result is consistent with the second encryption result, passes the terminal identity verification, and the terminal identity has no problem. The client information system utilizes the private key signature of the client information system and broadcasts the broadcast message of the client information system in the block chain network so as to confirm that the identity of the terminal is real and credible.
In step S303, the terminal broadcast message is authenticated using the customer information system broadcast message.
In one embodiment, after receiving the broadcast message of the customer information system, the base station queries the blockchain ledger by using the blockchain identifier of the customer information system to obtain the public key of the customer information system, and performs a first verification on the private key signature of the customer information system in the broadcast message of the customer information system by using the public key of the customer 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 S304, if the verification is passed, a usage approval message is returned to the terminal, and the terminal is provided with the usage frequency band.
And when the base station passes the first verification and the second verification, the terminal broadcast message is considered to be verified, the use approval message is returned to the terminal, and the service is provided for the terminal according to the base station expected to be accessed and the use frequency band in the terminal broadcast message.
It should be noted that step S301 and step S302 may be performed simultaneously, or may be performed sequentially, for example, step S301 is performed before step S302 is performed after step S; alternatively, step S302 precedes step S301.
In a modified embodiment of this embodiment, before step S301, the method further includes: acquiring historical data of a base station; predicting idle time periods of frequency spectrums of different frequency bands according to historical data of the base station; calculating the use price of the unit duration of the frequency spectrums of different frequency bands; the method comprises the steps that a private key of a base station is used for signing idle time intervals and unit use prices of frequency spectrums of different frequency bands to obtain base station broadcast messages; base station broadcast messages are broadcast in a blockchain network.
The historical data of the base station includes the usage of the spectrum of the base station, i.e. the usage of different frequency bands of the base station in the past, such as which frequency band is idle in what time period. According to the historical data of the base station, idle periods of different frequency bands can be predicted.
In addition, since the signal quality and the transmission rate of different frequency bands are different, the use prices of unit time length of different frequency bands are different. The embodiment can calculate the use price of the frequency spectrums of different frequency bands in unit time length.
And when the base station obtains the idle time periods and unit use price signatures of the frequency spectrums in different frequency bands, the base station obtains the broadcast message of the base station by using the private key signature of the base station. The base station broadcast message is then broadcast in the blockchain network. Therefore, the terminal can obtain the base station broadcast message through the block chain network, further obtain the idle time and the unit use price of the frequency spectrum of different frequency bands of the base station, and select the base station expected to be accessed and the use frequency band.
