Decentralized Communication Network for Home-Server-Independent Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks, such as those governed by the 3GPP MCS standard, limit access to communication services when a user is not connected to their 'home servers', restricting communication possibilities.
Innovation Solution
A decentralized communication network architecture where configuration information for user authentication and registration is duplicated across multiple servers, allowing users to authenticate and register with any server, and manage communication sessions in a distributed manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If configuration information is stored only on home servers, then centralized management is simplified, but user access to communication services is limited when not connected to home servers
Solution Approach 1:
The patent applies the copying principle by duplicating user configuration information across multiple servers in the network. Each server maintains a copy of the configuration data, enabling users to authenticate and access communication services on any server regardless of their home server connection status. This resolves the contradiction by sacrificing centralized storage simplicity to gain user access flexibility.
2Reliability
If communication management is centralized at home server level, then system control is simplified, but communication continuity is lost when home server connection is unavailable
Solution Approach 1:
The patent applies segmentation by dividing the centralized communication management function into distributed components across multiple servers. Each server can independently manage communication sessions for users registered with it, segmenting the monolithic home server control into smaller, independent management units. This enables communication continuity even when users cannot connect to their home servers.
3Ease of operation
If users can register with any server, then access availability is improved, but server synchronization complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-distributing user configuration information to all servers before users need to access services. This advance preparation eliminates the need for complex real-time synchronization when users register or move between servers, as the configuration data is already available locally at each server.

AI summary
One aspect of the invention relates to a communication network (200) allowing at least one user equipment (U1, U2, U3, U4), by means of configuration information, to access communication services, the communication being a private communication or a communication within a multimedia group to which the user equipment (U1, U2, U3, U4) is affiliated, the communication network (200) comprising a plurality of servers (S1, S2, S3, S4) and being characterized in that the configuration information of the user equipment (U1, U2, U3, U4) is configured in each server (S1, S2, S3, S4) which the user equipment (U1, U2, U3, U4) is authorized to access.
