RAN Data Center Pooling for Low-Latency 5GC Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge for mobile network service providers is how to optimally integrate 5G Core (5GC) network functions with radio access networks (RAN) across distributed data centers (DCs) while meeting service level agreements regarding redundancy, packet latency, and scaling requirements, which is complicated by the geographic distribution of DCs and RANs.
Innovation Solution
An automated approach is provided to select primary and backup data centers for radio base stations based on latency and geographical distance criteria, assigning 5GC network functions to pools that optimize integration, considering available computing resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data centers are geographically distributed to serve multiple radio base stations, then service coverage and redundancy are improved, but network latency and integration complexity increase
Solution Approach 1:
The system segments data centers into regional groups, each serving specific radio base stations within geographic proximity. This segmentation allows multiple data centers to provide redundancy while maintaining low latency by assigning each base station to nearby data centers, thus resolving the contradiction between geographic distribution for redundancy and latency reduction.
2Productivity
If data centers are geographically distributed across large areas, then service coverage and capacity scaling are improved, but network integration complexity and latency increase
Solution Approach 1:
The patent segments the network into regional data center groups that serve specific geographic areas. This segmentation enables independent management and scaling of each region without affecting others, reducing overall integration complexity while maintaining scaling capacity.
Solution Approach 2:
The system implements local quality by optimizing data center selection based on geographic proximity to radio base stations. Each base station is assigned to data centers in its local region, ensuring low latency and simplified integration while allowing global scaling through additional regional data centers.
3Ease of operation
If automated selection of data centers based on latency criteria is implemented, then access efficiency and quality of service are improved, but system complexity for automated management increases
Solution Approach 1:
The system implements self-service by enabling radio base stations to automatically select and connect to appropriate data centers based on pre-established latency criteria and geographic information. This automated selection process improves access efficiency while the standardized algorithms keep management complexity可控.

AI summary
A method, computer system, and computer program product are provided for facilitating radio access network integration with data centers. Mobile network configuration information is obtained identifying threshold latency and distance criteria and network function operating criteria. Data center information is obtained for a plurality of data centers. Latencies between a plurality of radio base stations and the plurality of data centers are determined. A primary data center and a backup data center are selected to interconnect with each radio base station based on a geographical distance between each data center and each radio base station satisfying the threshold distance and latency criteria. Network function pool configuration information is generated for the primary data center and the backup data center. A domain name system (DNS) server and a network repository function (NRF) are configured based on the network function pool configuration information.
