Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for connecting user devices to content servers introduce latency due to the distinction between radio access network (RAN) and core network functionalities, leading to inefficient data processing and resource utilization.
Innovation Solution
A unified RAN/multi-access edge computing (MEC) platform that integrates RAN, core network, and application functionalities, allowing data destined for low-latency applications to be processed locally at the edge of the RAN network, thereby establishing low-latency bearers that bypass the core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is routed through the core network for processing, then network coverage and connectivity are improved, but latency increases and real-time processing capability deteriorates
Solution Approach 1:
The patent segments the network processing path by separating low-latency data traffic from core network routing. Edge computing nodes are positioned at the network edge to handle time-sensitive applications locally, while the core network continues to provide broad connectivity. This segmentation allows simultaneous optimization of both connectivity coverage and latency performance.
Solution Approach 2:
The patent introduces edge computing nodes as intermediary elements between user devices and the core network. These intermediaries process low-latency data locally without requiring full core network traversal, thereby reducing latency while maintaining core network connectivity for non-time-sensitive traffic.
2Adaptability or versatility
If RAN and core network functionalities are separated into distinct mechanisms, then network architecture flexibility is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges RAN and core network functionalities into a unified edge computing platform. By co-locating computing, storage, and networking resources at the network edge, the system achieves both architectural flexibility and improved resource utilization. Resources are shared across multiple services and applications, eliminating waste from separate infrastructure deployments.
Solution Approach 2:
The unified edge computing platform provides multi-functional capabilities, serving both RAN operations and core network functions through a single infrastructure. This universal platform supports diverse applications including low-latency services, content delivery, and network management, thereby improving overall resource utilization while maintaining architectural flexibility.
3Ease of operation
If computing services are centralized in the core network, then service management simplicity is improved, but access speed and real-time capability deteriorate
Solution Approach 1:
The patent extends service delivery from a single centralized dimension to multiple distributed dimensions by deploying edge computing nodes throughout the network. This spatial distribution brings computing services physically closer to data sources and consumers, dramatically improving access speed while maintaining centralized management capabilities through orchestration systems.
Solution Approach 2:
The patent implements preliminary action by pre-positioning computing resources and data at network edge locations before they are needed. This anticipatory deployment of services at the edge enables immediate local processing without waiting for core network responses, thereby improving access speed while centralized systems continue to provide overall service management.

AI summary
A device can determine, based on a first packet flow associated with a first user device and application identifiers associated with applications accessible by the first user device, that a first packet associated with the first packet flow is destined for a low-latency application having a specified latency range. The device can identify a first low-latency bearer that satisfies the specified latency range associated with the low-latency application. The device can map the first packet flow to the first low-latency bearer.
