Network Slice Management Conflict Resolution via Policy Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the concurrent automated reconfiguration, optimization, and healing of network slice instances can lead to conflicts due to simultaneous requests for modifying shared network functions, necessitating enhanced coordination to prevent or resolve these conflicts and ensure optimal Quality of Service (QoS) delivery.
Innovation Solution
The implementation of a Communication Service Management Function (CSMF) and a Network Slice Management Function (NSMF) that coordinate management actions through pre-configured policies, allowing for automated reconfiguration, optimization, and healing of network slice instances while ensuring conflict resolution and data exposure to customers, thereby improving latency and bandwidth performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If concurrent automated reconfiguration, optimization, and healing actions are performed on network slice instances, then network automation and responsiveness are improved, but conflicts arise due to simultaneous modification requests on shared network functions
Solution Approach 1:
The system performs preliminary actions by evaluating multiple management action requests before execution, determining a safe execution order that prevents conflicts. The coordination mechanism assesses compatibility of concurrent requests and schedules them in an order that avoids harmful interactions, thus maintaining reliability while preserving automation.
Solution Approach 2:
A management action coordination mechanism acts as an intermediary between multiple management functions and the network slice instances. This coordinator receives, evaluates, and sequences management requests, mediating between concurrent operations to prevent conflicts while maintaining the automated nature of the system.
2Reliability
If multiple management actions are coordinated through evaluation and sequencing, then conflicts are prevented and reliability is improved, but additional coordination overhead increases processing time
Solution Approach 1:
The coordination mechanism applies partial evaluation by focusing assessment on specific conflict-prone aspects of management actions rather than进行全面 analysis. This selective approach prevents conflicts while minimizing the time overhead of the coordination process.
3Ease of operation
If network slice management data is exposed to communication service customers, then customer access and transparency are improved, but security and data protection requirements become more complex
Solution Approach 1:
The system applies local quality by providing differentiated data access where different customers receive different subsets of management data based on their specific needs and authorization levels. This selective exposure mechanism improves ease of operation for legitimate customers while maintaining security through granular control, avoiding the need for complex universal security mechanisms.
