Mobile Edge Computing Traffic Segregation Using Dedicated Bearers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network architectures face challenges in efficiently managing communication resources, particularly in segregating low latency traffic from non-latency sensitive traffic within a packet data network (PDN) using dedicated bearers.
Innovation Solution
The implementation of techniques that enable low latency traffic segregation within a PDN using dedicated bearers, where an edge user plane entity classifies traffic and directs low latency packets over dedicated bearers for local breakout, while non-latency sensitive traffic is directed over default bearers for central breakout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all traffic is processed on the edge user plane, then low latency traffic handling is improved, but edge compute resources are wasted on non-latency sensitive traffic
Solution Approach 1:
The patent segments traffic into low latency traffic and non-latency sensitive traffic, routing low latency traffic through dedicated bearers to the edge user plane for rapid processing, while directing non-latency sensitive traffic through default bearers to centralized user plane functions. This segmentation ensures that scarce edge compute resources are dedicated exclusively to latency-critical traffic, eliminating resource waste on non-latency traffic while maintaining optimal low latency performance.
2Productivity
If traffic segregation using dedicated bearers is implemented, then low latency traffic management is improved, but device complexity increases
Solution Approach 1:
The patent implements a dual-bearer architecture where both default bearers and dedicated bearers coexist within the same PDN connection. The edge user plane entity is designed with multi-functionality to handle both default bearer traffic (non-latency sensitive) and dedicated bearer traffic (low latency) through a unified processing framework. This universal design allows the network to support traffic segregation without requiring separate network infrastructures, thereby improving low latency traffic management while limiting the increase in overall system complexity.

AI summary
Presented herein are embodiments that provide mobile edge computing (MEC) with low latency traffic segregation within a packet data network (PDN) using dedicated bearers. Techniques are provided that are performed at an edge user plane entity and a control plane entity to coordinate the directing of low latency traffic over a dedicated bearer broken out at the edge, and to communicate normal latency traffic over a default bearer that is centrally broken out.
