Communication method, device and system based on block chain
Technical Field

Background
A radio wave is an electromagnetic wave existing in nature, and is distributed between a frequency range of 3Hz to 3000GHz, and radio waves in different bands have different propagation characteristics. Specifically, the lower the frequency of the radio wave, the longer the coverage distance, the stronger the diffraction ability; the high frequency band frequency resource is abundant, and the system capacity is large. Therefore, the mobile communication system considers the coverage effect and the capacity together when selecting the frequency band to be used.
In the field of mobile communications, the frequency band of radio waves (radio spectrum) is usually planned by a "static management strategy", which not only leads to an increasing shortage of radio spectrum, but also leads to a decrease in the utilization rate of licensed spectrum. In a current dynamic spectrum sharing mechanism of a base station, each base station can provide frequency services of different frequency bands, and under the mechanism, a terminal cannot autonomously select the frequency band of the base station, so that poor user experience is caused.

In addition, each base station may also periodically transmit information such as the usage of the spectrum of each frequency band and the usage price per unit time length (hereinafter, referred to as usage unit price) to the corresponding blockchain network by broadcasting.
In the block chain system, the base station, the terminal and the customer information system belong to one operator (such as an operator of the Unicom, Mobile or Telecommunications).

Wherein the blockchain system is a federation blockchain system.
Before the communication method provided in this embodiment is implemented, the first multi-card terminal may register in a non-blockchain manner (e.g., a manner in which the terminal performs business transaction in a business hall of an operator) at the operator (e.g., an operator in a unified messaging service, a mobile service, or a telecommunication service) to which the blockchain system belongs, and after the registration is successful, the first multi-card terminal successfully joins the blockchain system of the operator to which the first multi-card terminal belongs, and meanwhile, a client information system in the blockchain system stores registration information of the registered first multi-card terminal and a corresponding operator customer service password, and also stores a corresponding relationship list corresponding to the first multi-card terminal in the client information system, where the corresponding relationship list at least includes: the method comprises the steps of obtaining a corresponding relation among a block chain identifier corresponding to a main card terminal, a block chain identifier of at least one auxiliary card terminal, a terminal Number, a mobile subscriber integrated services digital network Number (MSISDN) of the main card terminal, a terminal identifier of the main card terminal, a mobile subscriber integrated services digital network Number (MSISDN) of the at least one auxiliary card terminal and a terminal identifier of the at least one auxiliary card terminal in the one-Number multi-card terminal, wherein the terminal identifier can be an International Mobile Subscriber Identity (IMSI).
Fig. 1 is a flowchart of a blockchain-based communication method provided by an embodiment of the present disclosure, which may be performed by a communication device, which may be implemented by software and/or hardware, and which may be integrated in a customer information system/server of an operator. As shown in fig. 1, the communication method includes:
step 11, obtaining a first broadcast message of a first terminal in the belonging block chain network, where the first broadcast message at least includes a frequency band of a first base station that the first terminal expects to use.
In the embodiment of the present disclosure, the first terminal may be a main card terminal in the aforementioned multi-card-one terminal, or may be the aforementioned at least one sub-card terminal.
In this embodiment of the present disclosure, a first terminal may search for base station information in its physical address range (physical location range) through a corresponding baseband processor module, extract a block chain identifier of a base station from the base station information, and broadcast a first broadcast message in a belonging block chain network, where the first broadcast message further includes the block chain identifier of the first terminal and a block chain identifier of a first base station that is expected to be accessed.
It should be noted that the baseband processor module corresponding to the first terminal may be a 2G/3G/4G/5G baseband processor module, and the baseband processor module is a module disposed in the first terminal, and belongs to the prior art, and details are not described here.
In the disclosed embodiment, the base stations are important components for transferring information in the mobile communication network, and the radio of each base station has a certain coverage area, and in order to ensure that there is no dead angle in communication, a part of the area is covered by a plurality of base stations. Therefore, when the first terminal searches for a base station within its own physical address range, it is often the case that one or more base stations are searched, and the first terminal may select a base station desired to access from the searched one or more base stations as the first base station and broadcast the first broadcast message in the belonging blockchain network.
In step 11, when the first terminal broadcasts the first broadcast message in the belonging blockchain network, the first broadcast message of the first terminal may be acquired from the belonging blockchain network.
And step 12, acquiring a second broadcast message of a second terminal in the affiliated block chain network, wherein the second broadcast message at least comprises a frequency band of a first base station expected to be used by the second terminal, and the first terminal and the second terminal are terminals with the same terminal number.
In the embodiment of the disclosure, the first terminal and the second terminal are one-number multi-card terminals, and the terminal numbers of the first terminal and the second terminal are the same. And when the first terminal is at least one sub-card terminal in the one-number multi-card terminal, the second terminal is the main card terminal.
In this embodiment of the present disclosure, the second terminal may search for base station information in its physical address range (physical location range) through the corresponding baseband processor module, extract a block chain identifier of the base station from the base station information, and broadcast a second broadcast message in the belonging block chain network, where the second broadcast message further includes the block chain identifier of the second terminal and the block chain identifier of the first base station that is expected to be accessed.
It should be noted that the baseband processor module corresponding to the second terminal may be a 2G/3G/4G/5G baseband processor module, and the baseband processor module is a module disposed in the second terminal, and belongs to the prior art, and details are not described here.
When the second terminal searches for a base station within its own physical address range, often in a situation where one or more base stations are searched, the second terminal may select a base station desired to access from the searched one or more base stations as the first base station, and broadcast the second broadcast message in the belonging blockchain network.
In step 12, when the second terminal broadcasts the second broadcast message in the belonging blockchain network, the second broadcast message of the second terminal may be acquired from the belonging blockchain network.
And step 13, inquiring whether the terminal number has a priority access service of a preset using frequency band.
In this disclosure, when a first multi-card terminal, that is, a terminal number corresponding to a first terminal and a second terminal, has subscribed to a priority access service of a preset use frequency band in advance, it indicates that the first terminal and the second terminal can simultaneously and preferentially access and use the preset use frequency band provided by the first base station, otherwise, it indicates that the first terminal and the second terminal do not have a right to simultaneously and preferentially access and use the preset use frequency band provided by the first base station.
Step 14, broadcasting a third broadcast message to the affiliated blockchain network, where the third broadcast message at least includes a frequency band of the first base station that the first terminal desires to use, a frequency band of the first base station that the second terminal desires to use, and a message indicating whether the terminal number has a priority access right of a preset use frequency band, so that the first base station provides the preset use frequency band to the first terminal and/or the second terminal according to the third broadcast message.

The binding relationship may be information for representing that the first terminal and the second terminal are the first multi-card terminal.
In the embodiment of the present disclosure, when it is found in step 13 that the terminal numbers corresponding to the first terminal and the second terminal have a priority access service for subscribing to the preset use frequency band, the third broadcast message broadcast in step 14 includes a message that the terminal number has a priority access right of the preset use frequency band; when it is found in step 13 that the terminal numbers corresponding to the first terminal and the second terminal do not subscribe to the priority access service of the preset use frequency band, the third broadcast message broadcast in step 14 includes a message that the terminal number does not have the priority access right of the preset use frequency band.
In this disclosure, when the third broadcast message includes a message that the terminal number has a priority access right of the preset use frequency band, the first base station may provide the preset use frequency band to the first terminal and the second terminal according to the third broadcast message, so that both the first terminal and the second terminal may access the communication network provided by the first base station based on the preset use frequency band provided by the first base station and perform communication operation.
In this disclosure, when the third broadcast message includes a message that the terminal number does not have a priority access right to the preset use frequency band, the first base station may provide the preset use frequency band to the first terminal or the second terminal according to the third broadcast message.
When the first terminal is a main card terminal in the first multi-card terminal, the first base station may preferentially provide the preset use frequency band to the first terminal according to the third broadcast message, so that the first terminal may preferentially access the communication network provided by the first base station based on the preset use frequency band provided by the first base station and perform communication operation. When the second terminal is a main card terminal in the one-number-multi-card terminal, the first base station may provide the preset use frequency band to the second terminal according to the third broadcast message, so that the second terminal may preferentially access the communication network provided by the first base station based on the preset use frequency band provided by the first base station and perform communication work.
