As shown in fig. 2, the method includes:
step S201, each base station node detects the spectrum usage state of each frequency band of itself at intervals of a preset time, and broadcasts a third broadcast message to the block chain, where the third broadcast message includes the spectrum usage information of each frequency band of itself.
Each base station node detects the frequency spectrum using state of each frequency band at preset time intervals, and sends out the detection result in the form of block chain broadcast message, and meanwhile, the broadcast message also comprises the frequency spectrum using price of each frequency band, and the frequency spectrum using state of each frequency band and the frequency spectrum using price of each frequency band form the frequency spectrum using information of each frequency band.

Step S203, the secondary card terminal node obtains the blockchain identifier of the peripheral available base station node, and sends a first broadcast message to the blockchain network, where the first broadcast message includes the blockchain identifier of the available base station node.
When the secondary card terminal node is located at a certain geographical position, the secondary card terminal node automatically searches for base station information of available base stations around the secondary card terminal node, where the base station information includes base station identification information, block chain identification information of the base station, and the like.
Step S204, the main card terminal node receives the first broadcast message, and inquires the frequency spectrum use information of each available base station node from the block chain account book according to the block chain identification of the available base station node.
In the present invention, a block chain account book stores spectrum usage information of each base station node, where the spectrum usage information includes: the frequency spectrum using state and the using price of each frequency band refer to the number of users of the frequency spectrum of each frequency band in the current time period, and the frequency spectrum using price of each frequency band is preset by an operator.

In this embodiment, after receiving the first broadcast message, the main card terminal node determines, according to a preset rule, a target base station node and a spectrum priority order of each frequency band of the target base station node from the available base station nodes based on spectrum usage information of the available base station nodes, where the target base station node refers to a base station node to which the main card terminal desires the secondary card terminal to access; the spectrum priority ranking of each frequency band of the target base station node refers to the priority sequence of the frequency spectrum allocated by the main card terminal when the auxiliary card terminal is expected to perform communication.
The second broadcast message comprises the frequency spectrum priority sequence of each frequency band of the target base station node, the identity information of the auxiliary card terminal node, the mobile phone number of the main card, the identity of the main card terminal node and the first encryption result.

And S208, the customer information system node encrypts the main card mobile phone number and the operator customer service password according to a preset encryption algorithm to obtain a second encryption result.
Step S209, the client information system node verifies whether the first encryption result and the second encryption result are consistent.

Step S211, the target base station node receives the fourth broadcast message and the second broadcast message.
Step S212, when the target base station node receives the fourth broadcast message and the second broadcast message, the target base station node stores the corresponding relation between the spectrum priority sequence of each frequency band and the identity identification information of the sub-card terminal node, so that when an access request sent by the sub-card terminal node is received, the spectrum communicated with the sub-card terminal node is distributed according to the spectrum priority sequence of each frequency band corresponding to the identity identification information of the sub-card terminal node.
In step S212, when the target base station node receives the fourth broadcast message, it indicates that the identity authentication of the node sending the second broadcast message by the client information system has been passed, and at this time, the information included in the second broadcast message may be stored.
It should be noted that, in this embodiment, when the target base station node stores the information in the second broadcast message, it may only store the correspondence between the spectrum priority ranking of each frequency band included in the second broadcast message and the identity information of the secondary card terminal node, or certainly store the correspondence between the spectrum priority ranking of each frequency band of all the target base station nodes included in the second broadcast message and the identity information of the secondary card terminal node, and it is not specifically limited in the present invention to store which information specifically, as long as the stored information includes the correspondence between the spectrum priority ranking of each frequency band and the identity information of the secondary card terminal node.
After the target base station node stores the corresponding relation between the frequency spectrum priority sequence of each frequency band and the identity identification information of the auxiliary card terminal node, when receiving an access request from the auxiliary card terminal node, the target base station node determines the frequency spectrum priority sequence of each frequency band corresponding to the auxiliary card terminal node through the identity identification of the auxiliary card terminal node, and therefore a proper frequency spectrum is selected for the auxiliary card terminal according to the sequence.
In addition, it should be noted that, in the present invention, the sending and receiving processes of each broadcast message (the first broadcast message, the second broadcast message, the third broadcast message, and the fourth broadcast message) may further perform a signature adding process and a signature verifying process, respectively, specifically, the signature added to the broadcast message is generated based on the private key of the sending node, the signature is verified by the receiving node using the public key of the broadcast node, the private key and the public key of the node are both stored in the block chain ledger, and the specific signature adding and verifying process belongs to the prior art in the field and is not described herein again. By adding the signature to the broadcast message, the security of the system for transmitting information can be further improved.
