Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized core network is used, then network elements can process a large quantity of users, but the network has a single point failure risk and cannot meet personalized user requirements
Solution Approach 1:
The patent segments the centralized core network into distributed digital reflections (DRs) deployed at multiple edge locations. Each DR independently serves users in its local area, eliminating the single point of failure risk while maintaining the ability to handle large numbers of users through distributed processing capacity.
Solution Approach 2:
The patent introduces a hierarchical architecture with two dimensions: centralized policy control (for coordination) and distributed user plane functions (for data processing). This dimensional separation allows personalized services through local DRs while maintaining overall network reliability through redundancy.
2Ease of operation
If a digital reflection is deployed on edge cloud for each terminal device, then user centric network architecture is achieved, but communication delay increases due to querying mapping system for addresses
Solution Approach 1:
The patent implements preliminary action by having the first digital reflection store the terminal device's binding information (including address mapping) in advance. When data needs to be transmitted, the first DR directly uses the pre-stored binding information to forward data to the second DR, eliminating the need for real-time mapping system queries and reducing communication delay.
3Device complexity
If centralized core network elements are used, then network management is simplified, but packet header overheads increase and communication efficiency decreases
Solution Approach 1:
The patent extracts the data processing functions from the centralized core network and places them at the edge through distributed digital reflections. This extraction reduces the amount of data that needs to be routed through centralized elements, thereby reducing packet header overheads and improving communication efficiency while maintaining manageable network complexity through automated DR coordination.

AI summary
This application provides a communication method and apparatus, to reduce a communication delay. The method includes: 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 a DR 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.
