Network Slice Resource Allocation via AMF Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network slicing technologies in 5G communications suffer from low radio resource utilization due to reliance on management plane configurations, which result in poor real-time performance and the need for large idle resource reservations, making it difficult to quickly adjust resources in response to network changes.
Innovation Solution
An access network device requests and updates radio resources based on running information of network slices or slice groups, allowing for real-time adjustments without relying solely on management plane configurations, by sending request messages to an AMF for resource allocation reference information, which includes statistical and prediction data to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network slices are configured through management plane configuration, then network slices can be logically isolated and organized, but radio resource utilization is low and real-time adjustment capability is poor
Solution Approach 1:
The patent implements a feedback mechanism where the access network device periodically requests running information from the AMF about network slice resource usage. Based on this feedback, the access network device dynamically adjusts radio resource allocation in real-time, transitioning from static management plane configuration to dynamic resource adjustment based on actual network conditions and demand.
Solution Approach 2:
The patent introduces dynamic resource adjustment capability at the access network level. Instead of relying solely on static management plane configurations, the system enables real-time changes in radio resource allocation based on current network state, user demand, and slice performance metrics, making the resource allocation system adaptive and flexible.
2Ease of operation
If large quantities of idle resources are reserved for network slice groups, then resource allocation can be performed, but real-time performance is poor and resource utilization is low
Solution Approach 1:
The access network device performs self-adjustment of radio resources based on running information about network slice usage. Instead of requiring continuous manual configuration or reservation from the management plane, the system enables the access network to autonomously optimize resource allocation based on real-time conditions, reducing the need for pre-reserved idle resources.
3Ease of manufacture
If network slice groups are configured with fixed resource allocation, then configuration is simple, but the system cannot quickly adjust when network changes occur
Solution Approach 1:
The system establishes a preliminary framework where the management plane provides initial network slice configurations and grouping. However, it also pre-configures the mechanism for real-time adjustments at the access network level, so that when network changes occur, the system can quickly adapt without requiring complete reconfiguration from the management plane.

AI summary
A method and an apparatus for allocating a resource to a network slice resolves a problem in the current technology that utilization of radio resource utilization cannot be improved. The method includes: sending, by an access network device, a request message to an AMF, where the request message is used to request resource allocation reference information of a network slice group, the resource allocation reference information includes running information of a network slice or running information of the network slice group, and the network slice belongs to the network slice group; after receiving the request message, sending, by the AMF, the resource allocation reference information to the access network device; receiving, by the access network device, the resource allocation reference information from the AMF; and updating, by the access network device, a radio resource of the network slice group based on the resource allocation by reference.
