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 mobile switching center on the calling side inquires the service control point node in the preset block chain about the affiliation of the operator of the mobile user terminal corresponding to the called number, whether the user terminal is a group user / whether it is related to the mobile The user terminal is in the same private network of the group, and the call is triggered to the multimedia telephony service application server corresponding to the called number through the mobile switching center; the call session control functional entity in the IMS domain is controlled by the call session in the preset block chain The functional entity node queries the HLR node for the session resource identifier of the called number, sends the call invitation message to the called side call session control functional entity and the called side service control point application server, and the called side service control point application server queries The location of the outgoing user terminal of the called user. 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...
