User Plane Session Routing for Low-Latency Edge Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current edge computing technologies face high transmission delays and communication costs in the process of edge applications obtaining data from central or other edge data networks, primarily due to non-3rd generation partnership project (3GPP) communication methods.
Innovation Solution
Implementing a communication method and apparatus that utilizes user plane network elements to transmit data through sessions, modifying source and destination addresses to facilitate direct data transfer between applications and data networks without dedicated lines, thereby reducing transmission delays and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If non-3GPP communication manner is used for edge application to obtain data from central network, then data transfer can be achieved, but transmission delay increases and communication costs increase
Solution Approach 1:
The patent introduces user plane network elements as intermediaries to facilitate data transfer between edge applications and central network. These network elements establish sessions that enable efficient data routing, reducing transmission delay and communication costs by optimizing the communication path rather than requiring direct connections.
Solution Approach 2:
The patent modifies communication parameters by implementing session-based data transfer with address modification. The user plane network elements change source and destination addresses during data transmission, enabling more efficient routing and reducing the need for dedicated lines, thereby lowering communication costs and transmission delay.
2Reliability
If dedicated lines are laid between first application and second data network, then data transfer reliability is improved, but device complexity and communication costs increase
Solution Approach 1:
The patent implements a universal session-based communication framework that can serve multiple applications and data networks. The user plane network elements handle various data transfer scenarios through a common session management mechanism, eliminating the need for separate dedicated lines for each application while maintaining reliable data transfer.
Solution Approach 2:
By introducing user plane network elements as intermediaries, the patent enables reliable data transfer without requiring direct dedicated lines between applications and data networks. These intermediaries manage sessions and address translation, ensuring reliable communication while reducing infrastructure complexity.

AI summary
This application provides a communication method and apparatus. The method includes: A first user plane network element receives first data, where a source address of the first data is a first address, the first address is an address of a first application, the first application serves a terminal device, and the first application corresponds to a first data network; and the first user plane network element sends the first data to a second user plane network element through a first session, where the first session is a session of the terminal device or a session corresponding to the first application, and the second user plane network element corresponds to a second data network; and/or the first user plane network element receives second data from the second user plane network element through the first session, and the first user plane network element sends the second data to the first application.
