Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks are network-centric, leading to centralized core network elements that are vulnerable to single point failures and unable to meet personalized user requirements, with mobility communication challenges due to tunnel mechanisms causing excessive packet header overheads and non-optimal paths.
Innovation Solution
Implement a user-centric network architecture with digital reflections (DRs) deployed on edge clouds, utilizing twin-globally unique temporary identities (TWIN-GUTIs) and location-identifier separation to facilitate direct communication between terminal devices, reducing the need for centralized mapping queries and minimizing communication delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized core network elements are used, then network management and resource allocation are simplified, but single point failure risk increases and user personalized requirements cannot be met
Solution Approach 1:
The patent segments the centralized core network into distributed edge computing nodes deployed at multiple locations. Each edge node independently manages local user sessions, eliminating the single point of failure in centralized architecture while maintaining manageable complexity through standardized interfaces between nodes.
Solution Approach 2:
The patent transitions from a vertical hierarchical network architecture to a horizontal distributed architecture across multiple edge nodes. This dimensional shift allows the system to scale out rather than scale up, reducing centralized control complexity while improving reliability through redundancy.
2Adaptability or versatility
If tunnel mechanisms are used for mobility communication, then network coverage is extended, but packet header overheads increase and communication delay increases
Solution Approach 1:
The patent extracts the tunneling mechanism from the core network and implements direct routing at the edge. User data is routed directly between edge nodes without passing through centralized tunnels, removing the source of excessive header overheads and reducing communication delay while maintaining network coverage through distributed edge deployment.
Solution Approach 2:
The patent introduces a location-identifier separation mechanism as an intermediary between mobility management and data routing. This allows the network to track user locations for coverage extension while enabling direct data paths that bypass traditional tunnel intermediaries, reducing overhead and delay.
3Adaptability or versatility
If digital reflections are dynamically migrated to MEC, then user centric architecture is achieved, but communication between terminal devices becomes complex
Solution Approach 1:
The patent performs preliminary binding between terminal devices and edge computing nodes before actual communication occurs. By pre-establishing binding relationships and caching routing information at edge nodes, the system enables user-centric architecture while avoiding complex real-time resolution operations during data transmission.
Solution Approach 2:
The patent creates local copies of routing and location information at each edge node rather than relying on centralized databases. This copying approach enables distributed user-centric routing decisions while simplifying communication complexity through local caching and direct routing capabilities.

AI summary
This application provides methods and apparatuses for communication. In an example method, a first digital reflection (DR) receives a first message, where the first message includes data to be sent to a first terminal device and an identifier of the first terminal device, and the first DR is associated with the first terminal device. The first DR transmits the data to the first terminal device based on a local locator (LLOC) of the first terminal device, where the first DR stores a twin-globally unique temporary identity (TWIN-GUTI) of the first terminal device, the TWIN-GUTI includes the LLOC, the LLOC corresponds to the identifier of the first terminal device, the first DR is deployed on first multi-access edge computing (MEC), and the TWIN-GUTI is generated by the first MEC.
