MEC Co-location with RAN for Low-Latency Service Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular networks, particularly 5G networks, face challenges in providing optimal low-latency services due to the lack of real-time access to user and network information, which hinders dynamic and proactive decision-making by Multi-access Edge Computing (MEC) platforms.
Innovation Solution
Integrating MEC equipment with Radio Access Network (RAN) facilities by exposing application programming interfaces (APIs) to allow MEC platforms to access RAN information, enabling co-location and real-time data exchange for optimizing services based on network conditions, and deploying core elements alongside RAN nodes to enhance MEC operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If MEC platforms operate independently without integration with RAN facilities, then device complexity is reduced and ease of operation is maintained, but latency cannot be optimized and real-time access to network information is lost
Solution Approach 1:
The patent merges MEC platforms with RAN facilities by co-locating MEC servers within RAN infrastructure and establishing direct API interfaces between RAN nodes and MEC platforms. This integration allows MEC to access real-time RAN information (user equipment data, network conditions, radio resource status) without complex external communications, thereby reducing latency while managing complexity through standardized interface definitions.
2Reliability
If MEC platforms access RAN information through exposed APIs, then service quality and dynamic decision-making are improved, but device complexity and integration difficulty increase
Solution Approach 1:
The patent implements universal API interfaces that enable MEC platforms to access multiple types of RAN information (user equipment information, network condition data, radio resource status) through a single standardized interface framework. This multi-functional API design improves service quality by providing comprehensive real-time data access while reducing integration complexity through a unified interface standard that handles diverse information types consistently.
Solution Approach 2:
The patent introduces standardized API interfaces as intermediary layers between RAN nodes and MEC platforms. These APIs act as mediators that translate complex RAN internal data structures into standardized formats accessible by MEC applications, thereby improving service quality through reliable data access while shielding MEC from RAN implementation complexities.
3Speed
If MEC equipment is co-located with RAN nodes, then real-time data exchange and latency reduction are achieved, but device complexity and deployment difficulty increase
Solution Approach 1:
The patent co-locates MEC servers physically within RAN infrastructure facilities, merging two previously separate systems into a single integrated deployment. This physical merging enables direct high-speed data exchange between RAN nodes and MEC platforms, achieving real-time latency optimization. Deployment complexity is managed by leveraging existing RAN facility infrastructure (power, cooling, housing) rather than requiring separate dedicated MEC facilities.

AI summary
A Multi-access Edge Computing (MEC) device receives first parameters associated with a user device from a first radio access network (RAN) device. The MEC device performs functions associated with an application being executed by the user device and the MEC device is co-located with the RAN device. The MEC device receives second parameters associated with the user device from a core network device. The MEC device modifies performance of the functions based on the received first and second parameters and provides third parameters associated with the user device to a second RAN device that is co-located with the MEC device for adjusting performance of a network.
