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. In addition, in the created block of the block chain, information such as block chain identifiers and public keys of the terminal, the base station and the customer information system node is stored, and the block chain is managed as an initial node of 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, at least one piece of base station information for which a base station service can be provided is acquired.
The base stations are important components for transmitting information in a mobile communication network, and the radio of each base station has a certain coverage area, and in order to ensure that the communication is free of dead angles, 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.
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. The base station also predicts idle time intervals of the spectrum use of different frequency bands according to the historical data, for example, the idle time intervals of the spectrum use of different frequency bands in the current time period are predicted according to the historical use data of the spectrum of different frequency bands. The base station also calculates the use price of the frequency spectrum of different frequency bands in unit time length.
Each base station signs the idle time of the frequency spectrum use of different frequency bands and the use price of unit time length by using the own private key according to a certain time interval to obtain the base station broadcast message, and then broadcasts the base station broadcast message in the block chain network, so that the terminal can conveniently obtain the frequency spectrum use conditions and use prices of different base stations, and selects a proper base station and frequency spectrum to provide communication service for the base station and the frequency spectrum.
In step S102, a base station broadcast message is acquired in the block chain network according to the base station information.
The base station information includes a code of the base station, the base station broadcast message at least includes frequency spectrum information that can be provided and a use price of a frequency band, and the frequency spectrum information refers to a frequency spectrum of the frequency band that can be provided by the base station.
The terminal searches the base station information in the physical address range through the baseband processor module, extracts the block chain identification of the base station from the base station information, and searches the corresponding base station broadcast information in the block chain network according to the block chain identification of the base station.
It should be noted that the baseband processor module is a module in a mobile communication network disposed in the terminal, and belongs to the prior art, and is not described herein again.
In one embodiment, a base station blockchain identification is extracted from base station information; and acquiring the base station broadcast message in the block chain network according to the base station block chain identifier.
For example, the terminal searches for base station a and base station B at the current physical address, that is, both base station a and base station B can provide mobile communication service for the terminal, obtain respective base station messages of base station a and base station B, obtain the block chain identifier of base station a from the base station message of base station a, and obtain the block chain identifier of base station B from the base station message of base station B. In the block chain network, the terminal obtains the broadcast message of the base station A according to the block chain identifier of the base station A, obtains the broadcast message of the base station B according to the block chain identifier of the base station B, then compares the frequency spectrum use conditions and the use prices of different frequency spectrums of the base station A and the base station B, and selects the base station and the frequency band which are expected to be accessed.
In step S103, an accessed base station and a frequency band used by the accessed base station are selected according to the base station broadcast message.
And when the terminal acquires the base station broadcast message from the block chain network, selecting the base station and the frequency band which are expected to be accessed from the base station broadcast message.
When the terminal searches a base station, the used frequency band is selected according to the free frequency spectrum and the use price provided in the broadcast message of the base station. When the terminal searches for two or more base stations, the terminal comprehensively considers the use price factors of different base stations, different frequency bands and frequency bands according to the broadcast messages of the base stations, and selects the base station and the frequency band for providing communication service for the terminal.
In step S104, a terminal broadcast message is generated and broadcast in the blockchain network.
The terminal broadcast message includes a base station expected to be accessed, a frequency band expected to be used, a block chain identifier of the terminal and a terminal identification code.
In one embodiment, the terminal uses its own private key to sign the base station expected to be accessed, the frequency band expected to be used, the block chain identifier of the terminal and the terminal identification code in the block chain network, obtains the terminal broadcast message, and then broadcasts the terminal broadcast message in the block chain network.
In one embodiment, the terminal broadcast message further includes a first encryption result, i.e. a first encryption result calculated by the terminal identification code and the operator service password according to a predetermined algorithm. The first encryption result is used for subsequent authentication, as described below.
In step S105, the frequency band provided by the base station is used in response to the grant use message of the base station.
And after receiving the frequency band use request of the terminal, the base station allocates the frequency band expected to be used by the terminal for the terminal.
In one embodiment, the base station verifies the terminal to determine whether the terminal uses the base station and the corresponding frequency band. Specifically, the base station obtains a terminal broadcast message in a block chain network, obtains a block chain identifier of the terminal from the terminal broadcast message, then queries a block chain account book, obtains a public key of the terminal, and then verifies a private key signature of the terminal broadcast message. And meanwhile, obtaining the broadcast message of the client information system in the block chain network, obtaining the block chain identification of the client information system from the broadcast message of the client information system, then inquiring the block chain account book, obtaining the public key of the client information system, and then verifying the private key signature of the broadcast message of the client information system. And when the private key signature of the broadcast message of the terminal and the private key signature of the broadcast message of the client information system are verified, the terminal is a legal terminal and agrees to use the frequency band of the base station.
It should be noted that the broadcast message of the client information system is a message that the client information system sends to the blockchain network after verifying the terminal identity. Specifically, after receiving the terminal broadcast message, the client information system queries the blockchain account book according to the blockchain identifier of the terminal, finds the public key of the terminal, and verifies the private key signature of the terminal broadcast message by using the public key. If the verification is passed, searching the operator service password reserved by the terminal in the client information system according to the terminal identification number in the terminal broadcast message, and then calculating the operator service password and the operator service password according to a predetermined algorithm to obtain a second encryption result. The client information system compares the first encryption result and the second encryption result obtained in step S104, if the first encryption result and the second encryption result are consistent, it is considered that there is no problem with the user identity using the terminal, and the client information system sends the client information system broadcast message to the block chain network after signing with its own private key to indicate that the identity of the terminal is confirmed to be authentic and trusted.
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, broadcasts the base station broadcast message in the blockchain network, and uses the selected accessed base station and frequency band after receiving the message that the base station requesting to access agrees to use the frequency band, so that the terminal can select the accessed base station and frequency band by itself, and user experience is improved. In addition, by using a trust mechanism of the block chain network and the non-falsification characteristic of the block chain account book, the terminal is safer and more credible when selecting the base station and the frequency band, the identity of the terminal is conveniently verified by the base station, all information has traceability, the safety and benefits of the base station and the terminal are guaranteed, and the voice call and network speed experience of the intelligent terminal are improved.
The embodiment also provides a mobile communication method applied to the base station. As shown in fig. 2, the mobile communication method includes the steps of:
in step S201, a base station broadcast message is broadcast in a block chain network at certain time intervals.
The base station broadcast message at least comprises a base station block chain identifier, available spectrum information and a frequency band use price. A base station blockchain identity is an identity used to identify a base station in a blockchain network.
It should be noted that the frequency spectrum provided by each base station is divided into different frequency bands, and the use cases of the frequency spectrums in different frequency bands are different. Therefore, each base station detects the use condition of the own frequency spectrum in real time.
In one embodiment, each base station uses its own private key to sign the idle time of the spectrum usage of different frequency bands and the usage price of unit duration 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, so that a terminal can conveniently obtain the spectrum usage and usage prices of different base stations, and select a proper base station and spectrum to provide communication service for the terminal.
In another embodiment, the base station further predicts the idle periods of the spectrum usage of different frequency bands according to the historical data, such as predicting the idle periods of the spectrum usage of different frequency bands in the current time period according to the historical usage data of the spectrum of different frequency bands. The base station also calculates the use price of the frequency spectrum of different frequency bands in unit time length. Specifically, before step S201, the method further includes: acquiring historical data of a base station, wherein the historical data of the base station comprises the frequency spectrum use condition of the 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; and obtaining the base station broadcast message after signing the idle time and the unit use price of the frequency spectrum of different frequency bands by using the private key of the base station.
In step S202, the used frequency band is provided for the terminal in response to the access base station and the used frequency band selected by the terminal.
After receiving the request of the terminal for accessing and using the frequency band, the base station provides communication service for the terminal according to the request of the terminal.
It should be noted that the terminal selects the accessed base station and the used frequency band through step S102 and step S103, which is not described herein again.
In one embodiment, before step S201, the method further includes: acquiring a public key of a terminal and a public key of an information service system, and after verifying the identity of the terminal, the information service system signs by using a private key and broadcasts in a block chain network;
verifying the private key signature of the terminal and the private key signature of the information service system respectively by using the public key of the terminal and the public key of the information service system, and providing a used frequency band for the terminal if the verification is passed; if the authentication is not passed, the communication service is stopped.
Specifically, the base station obtains a terminal broadcast message in a block chain network, obtains a block chain identifier of the terminal from the terminal broadcast message, then queries a block chain account book, obtains a public key of the terminal, and then verifies a private key signature of the terminal broadcast message. And meanwhile, obtaining the broadcast message of the client information system in the block chain network, obtaining the block chain identification of the client information system from the broadcast message of the client information system, then inquiring the block chain account book, obtaining the public key of the client information system, and then verifying the private key signature of the broadcast message of the client information system. And when the private key signature of the broadcast message of the terminal and the private key signature of the broadcast message of the client information system are verified, the terminal is a legal terminal and agrees to use the frequency band of the base station.
It should be noted that the broadcast message of the client information system is a message that the client information system sends to the blockchain network after verifying the terminal identity. Specifically, after receiving the terminal broadcast message, the client information system queries the blockchain account book according to the blockchain identifier of the terminal, finds the public key of the terminal, and verifies the private key signature of the terminal broadcast message by using the public key. If the verification is passed, searching the operator service password reserved by the terminal in the client information system according to the terminal identification number in the terminal broadcast message, and then calculating the operator service password and the operator service password according to a predetermined algorithm to obtain a second encryption result.
