Blockchain-based communication method and blockchain-based communication system

Abstract

The invention belongs to the technical field of blockchain, and relates to a communication method and system based on blockchain. The method at least includes: the call session control function entity of the calling side queries the service control point node for the operator affiliation and user terminal corresponding to the called number through the call session control function entity node in the preset blockchain. Whether the terminal is a group user / whether it is in the same group private network as the portable user terminal, the application server of the calling side service control point sends a call invitation message to the calling side call session control function entity; the calling side call session control function entity sends a call invitation message to the preset The home location register node in the set block chain queries the operator information and identity information of the carried-out user terminal, queries the selection of the access domain of the carried-out user terminal, and according to the called number and the called number with the added routing code of the carried-out user terminal The domain name routes the call to the interworking network elements of the IMS domain and other networks. It can effectively guarantee the normal communication of WVPN users who port their numbers to the network.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and relates to a communication method based on blockchain and a communication system based on blockchain. Background technique [0002] VoLTE (Voice over LTE, LTE network direct transmission) is a voice service in the data domain of the LTE network based on IMS (IP Multimedia Subsystem, IP Multimedia Subsystem). IMS is composed of all functional entities that can provide multimedia services, enabling operators to provide their users with multimedia services based on Internet applications, services and protocols. The LTE network is an all-IP network, and all services are carried on the data domain, which can realize the unification of data and voice services under the same network. With the development of science and technology, terminals (such as mobile phones, etc.) have become a necessity in people's lives. And as people's quality of life continues to improve, they have higher requirements...
