Blockchain Session Routing for Roaming Across Private SIP Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SIP communication networks are isolated and cannot interconnect with each other, and terminals cannot roam between private communication systems without registration, limiting user convenience and network flexibility.
Innovation Solution
A method and system for a communication session using blockchain technology to determine terminal session states based on transaction records, enabling seamless connection and authentication across different networks through blockchain address session states and unified identity management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If private communication networks use proprietary physical connections to ensure security and reliability, then network security and reliability are improved, but network interconnectivity and flexibility deteriorate
Solution Approach 1:
The patent introduces a visiting server as an intermediary component that enables terminals from different private communication networks to interact without direct physical connections. The visiting server acts as a mediator that receives session requests from visiting terminals, determines session states based on transaction records, and establishes communication routes through the blockchain network, thereby achieving network interconnectivity while maintaining the security boundaries of private networks.
Solution Approach 2:
The patent creates a universal blockchain-based communication layer that works across multiple private communication networks. The session state determination mechanism and transaction record verification system provide a multi-functional platform that enables authentication, session management, and interconnection services across different network domains, allowing the system to adapt to various network environments without requiring proprietary physical connections for each pair of networks.
2Ease of operation
If SIP terminals roam between internal communication systems, then user mobility is improved, but registration complexity increases
Solution Approach 1:
The patent implements a self-service registration mechanism where terminals automatically perform session state determination and authentication by presenting their blockchain addresses to the visiting server. The system autonomously queries transaction records, verifies session states, and establishes connections without requiring manual registration operations from users, thereby maintaining ease of operation while enabling roaming across multiple communication systems.
3Adaptability or versatility
If blockchain-based identity authentication is implemented across networks, then network flexibility is improved, but system complexity increases
Solution Approach 1:
The patent segments the authentication system into distinct functional components: terminal devices that generate blockchain addresses, visiting servers that determine session states, and a blockchain network that stores transaction records. This segmentation allows each component to operate independently with well-defined interfaces, reducing overall system complexity while enabling flexible blockchain-based authentication across multiple networks.
Data Source
AI summary
The present application discloses a method, system and storage medium for a communication session, involving blockchain technology. The present application sends a session request message based on a first terminal blockchain address session state, where the session request message includes a session request message identifier, a first terminal session account, and the first terminal session account includes: the first terminal blockchain address or an address mapped one-in-one to the first terminal blockchain address, and a first terminal home server connection address, the first terminal blockchain address session state is determined based on a transaction record between a visiting server blockchain address and the first terminal blockchain address; receives a session response message corresponding to the session request message identifier. By means of the present application, the visiting server can provide connection communication service for any blockchain user, which improves the convenience of terminal communication.
