Group user communication method and system based on blockchain

Abstract

The invention belongs to the field of blockchain, and relates to a group user communication method and system based on blockchain. The method comprises the steps that a calling session control function entity of a calling party triggers a calling side service control point application server according to calling subscription information, and receives a calling invitation message sent by the calling side service network control point application server, wherein the calling invitation message comprises a long number of a carry-out user terminal; a calling session control function entity of the called party triggers a called side service control point application server according to the called subscription information, and obtains the position information of the carry-out user terminal through the called side service control point application server and an affiliated subscription user server; and the calling session control function entity of the called number completes the IP connectivity bearer control operation when the called number is accessed to an IMS domain in a intercommunication network element, so that the ringing message of the carry-out user terminal is forwarded to a user terminal from a second network.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a group user communication method and system based on block chains. Background technique [0002] 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 for consumer experience. [0003] 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-based 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...

Problems solved by technology

However, this makes operators not only need to carry out technical preparations, database construction, and network transformation, but also need to add corresponding equipment, expand and transform existing equipment, and also need to solve billing, number query, and some management issues. The realization of technology requires huge investment, but also takes a certain amount of time

Although the former Ministry of Information Industry required mobile operators to implement the policy of "carrying a number to a package" policy, due to the large differences in the capabilities of supporting systems among operators in various regions, it is difficult to integrate different billing and business analysis systems, making many operators fully The timetable for implementing the policy has been significantly delayed
