Communication method based on blockchain and communication system based on blockchain

Abstract

The invention belongs to the field of a blockchain and specifically relates to a communication method and system based on the blockchain. The method at least comprises the steps that a calling side mobile switching center queries an operator subordination relationship of a number portability user terminal corresponding to a called number, and queries whether the user terminal is a group user or nor / whether the user terminal and the number portability user terminal are located in the same group private network or not, to a business control point node in a preset block chain; a call is triggeredby the mobile switching center to a multimedia telephone service application server corresponding to the called number; a call session control function entity in an IMS (IP Multimedia Subsystem) domain queries a session resource identity of the called number, to a home location register node, through utilization of a call session control function entity node in the preset block chain, and sends acall invite message to the called side call session control function entity and the called side business control point application server; and the called side business control point application server queries a location of the number portability user terminal of a called user. Normal communication of a number portability WVPN (Wireless Virtual Private Network) user can be effectively ensured.

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...
