Base Station Slice Manager for Local Radio Resource Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing systems face challenges in quickly addressing local issues affecting latency and throughput metrics at individual base stations, as centralized orchestrators may take time to recognize and rectify problems, leading to persistent issues and negative user experiences.
Innovation Solution
Implementing a real-time slice manager at the base station to dynamically adjust and manage radio resources among network slices based on local input factors, such as radio conditions, latency, and throughput, allowing for reallocation of spectrum and adjustment of resource attributes to meet performance goals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized slice orchestrator is used to manage network slices, then network resource allocation can be coordinated across the entire network, but local performance issues at individual base stations cannot be quickly addressed
Solution Approach 1:
The patent segments the centralized slice orchestrator's functions by introducing a local slice manager at each base station. This local manager handles real-time radio resource management for network slices independently, while the centralized orchestrator maintains overall coordination. This segmentation enables rapid local response to performance issues without waiting for centralized intervention, while preserving network-wide resource allocation capabilities.
Solution Approach 2:
The patent implements local quality by enabling each base station to autonomously manage its own network slice resources through a local slice manager. This allows each base station to adapt radio resource allocation to its specific local conditions (traffic patterns, radio environment, slice requirements) rather than applying uniform centralized control, thereby quickly addressing local performance issues.
2Adaptability or versatility
If centralized orchestrators manage all radio resource allocation, then consistent network-wide policies can be enforced, but local base stations cannot dynamically adapt to changing local conditions
Solution Approach 1:
The management system is segmented into two layers: a centralized slice orchestrator for high-level policy and resource coordination, and local slice managers at each base station for real-time adaptive radio resource management. This segmentation enables local adaptation without requiring complete decentralization, maintaining manageable system complexity through clear division of responsibilities.
Solution Approach 2:
The patent introduces dynamic adaptation at the local level through the slice manager, which can reallocate radio resources among network slices in real-time based on changing local conditions (traffic demand, radio channel quality, slice performance requirements). This dynamic capability allows the system to adapt to local variations while the centralized orchestrator maintains overall policy consistency.

AI summary
A real-time slice manager at a base station of a telecommunication network can manage radio resources allocated to network slices. The real-time slice manager can receive input factors associated with one or more network slices, including loading information, latency information, radio conditions, and other input factors. If the real-time slice manager determines that a network slice is not meeting a goal, such as a goal defined in a Service Level Agreement (SLA), the real-time slice manager can locally adjust radio resources allocated to one or more network slices, and/or treatment of network slices in a transport link or core network, to increase the likelihood that the network slice will meet the goal. The real-time slice manager can thus dynamically manage network slices at the base station to efficiently use available radio resources, manage network functions in the core network and/or transport link, and meet goals for the network slices.
