Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the block chain based communication method and the block chain based communication system in further detail with reference to the accompanying drawings and the detailed description.
The embodiment provides a communication method based on a block chain, which avoids the technical disadvantages of poor communication effect and high cost in the prior art, and achieves the technical effect of saving cost on the premise of ensuring normal communication of a user.
As shown in fig. 1, the block chain based communication method includes the steps of:
step S100): when the first user terminal registered through VoLTE is switched into a second network by a first network number portability, the second user terminal is used as a calling party, and the first user terminal is used as a called party, the second user terminal sends a call invitation message to a gateway mobile switching center through a base station.
In this step, the first user terminal is the first network before the number portability and is the second network after the number portability, and the first user terminal is registered through VoLTE. When the second user terminal initiates a call invitation to the first user terminal, the second user terminal sends the call invitation information to the gateway mobile switching center through the base station, so as to realize the conversation between the two users. Moreover, the method is particularly suitable for the communication process that the second user terminal is also a VoLTE user and the second user terminal is a call invitation initiated in the circuit domain.
Wherein, number portability: the number portability and the number-changing-free mobile phone are the same as those of a mobile telecommunication operator, for example, a mobile phone user with a mobile number is switched to a Chinese telecommunication network or a Chinese communication network to enjoy telecommunication operation services provided by the Chinese telecommunication or the Chinese communication. The number portability network mainly comprises two types of fixed number portability and mobile number portability. Number portability helps to support new operators, forcing them to quickly enter the market. The implementation of number portability is considered a measure of the benefit to all but the consumer, national and telecommunications industries. The number portability is beneficial to consumers and optimizing the market structure, and effective competition is realized and the welfare of the consumers is improved through the control measures of the market. For the consumer, number portability can reduce the user's network forwarding cost. For the country, number portability can save number resources. The number portability can break the dominance of the existing telecom operators, thereby promoting market competition and optimizing market structure. After the number portability is implemented, the number resources are generally managed by a third party in a centralized way, and social resources are also saved.
Step S200): and the gateway mobile switching center initiates a query message to a home location register node corresponding to a second network in a preset block chain, so that the home location register node corresponding to the second network determines the address of the application server corresponding to the first user terminal according to the pre-registered information and sends the address to the gateway mobile switching center.
In the present embodiment, by combining the block chain technique with the communication technique, the normal communication of the user is ensured. The blockchain in this embodiment has the following nodes: user node, home location register node (including connecting home location register node, telecom home location register node, mobile home location register node) of each operator, and office node. In the communication process, when a calling party or a called party relates to the calling and the action of a home location register, the calling party or the called party actively inquires a home location register node of a preset block chain or updates information after execution, so that the latest attribute information of the two communication parties in an operator is obtained through respective corresponding list inquiry, the information of the corresponding home location register in the communication network of the operator is configured according to the latest attribute information, and other network element equipment in the operator is butted.
A blockchain is a decentralized database that contains a list of what are called blocks, with records that are growing and aligned. Each tile contains a timestamp and a link to the previous tile: the blockchain is designed so that the data is not tamperable — once recorded, the data in one block will not be reversible. The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. A Blockchain (Blockchain) is essentially a decentralized database, which is a series of data blocks associated by using cryptography, and each data block contains information of one network interaction for verifying the validity (anti-counterfeiting) of the information and generating the next block. In a narrow sense, the blockchain is a distributed account book which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed in a cryptographic mode and cannot be tampered and forged. Broadly, the blockchain technique is a completely new distributed infrastructure and computing that utilizes blockchain data structures to verify and store data, distributed node consensus algorithms to generate and update data, cryptographic means to secure data transmission and access, and intelligent contracts composed of automated script code to program and manipulate data. Blockchain design is a protective measure, such as (applied to) highly fault-tolerant distributed computing systems.

Wherein the user information includes: and the prefix, the telephone number and other information corresponding to the first user terminal.
Step S400): when the first user terminal selects the circuit domain in the IMS network, the call session control function entity sends the call invite message to the called call session control function entity, so that the called call session control function entity performs a call continuation process, so that the ringing message corresponding to the first user terminal is forwarded from the called network to the second user terminal.
In this step, after the call session control function entity completes the IP connectivity bearer control operation, the ringing message of the called user is forwarded from the called network to the calling party and a response is made.

Such as: the second network sends query requests to five nodes adjacent to the second network, and all five nodes respond to the query requests. That is, the five nodes all inform the second network of who is the created block. If the feedback information of the five nodes is the same, the second network block "a is a created block" is informed, and the second network confirms that the block a is a created block.
However, if three of the five nodes inform the second network that the created block is block B, and two nodes inform the second network that the created block is block a, the second network identifies block B as a created block. That is, when the feedback information obtained by the second network is different, the feedback information with the most same feedback information is selected, and the block corresponding to the feedback information is the created block.
