Distributed Mobility Management for Enterprise Wireless Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized packet cores in mobile communication systems, especially in smaller deployments with fewer access points, lead to poor network latency and cumbersome management, making it difficult to integrate with broader enterprise networks.
Innovation Solution
Implementing a distributed mobility management functionality where each on-premise access point co-locates mobility management and packet routing and forwarding functionalities, reducing the burden of a centralized packet core and enabling efficient wireless network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized packet core is deployed, then management services are provided for the mobile environment, but network latency increases and management becomes cumbersome in smaller deployments
Solution Approach 1:
The centralized packet core is segmented into distributed mobility management entities (MMEs), with each access point having its own co-located MME. This segmentation distributes the management functionality across multiple independent units, reducing centralization bottlenecks and network latency while maintaining reliable management services locally at each access point.
Solution Approach 2:
The architecture transitions from a single centralized dimension to a multi-dimensional distributed structure where mobility management functionality is replicated across multiple access points. Each access point operates independently with its own MME, creating a parallel distributed system that reduces latency while providing comprehensive management coverage.
2Reliability
If a centralized packet core is deployed, then management services are provided for the mobile environment, but deployment complexity increases for smaller enterprises
Solution Approach 1:
The centralized packet core is segmented into distributed mobility management entities (MMEs), with each access point having its own co-located MME. This segmentation distributes the management functionality across multiple independent units, reducing centralization bottlenecks and network latency while maintaining reliable management services locally at each access point.
Solution Approach 2:
Each access point with its co-located MME operates autonomously, performing mobility management functions locally without requiring complex centralized coordination. This self-service capability simplifies deployment for smaller enterprises by eliminating the need for complex centralized infrastructure while maintaining reliable management services.
3Loss of time
If mobility management functionality is distributed to each access point, then network latency is reduced and deployment is simplified, but computational burden at each access point increases
Solution Approach 1:
Each access point is equipped with a co-located MME that performs mobility management functions specifically for its local coverage area. This local quality approach ensures that computational resources are utilized efficiently at each location, processing only the mobility management tasks relevant to that specific access point rather than handling all network traffic centrally.
