Core Network Control Plane Configuration for Multi-Slice 5G Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G system architectures lack a method to generate an accurate control plane configuration for user equipment (UE) simultaneously connected to multiple network slices with different requirements, leading to sub-optimal configurations that affect network slice performance.
Innovation Solution
A core network entity in the wireless communication system receives a request for a control plane configuration from the access and mobility management function (AMF), generates the configuration based on the received request, and transmits it back to the AMF, ensuring the configuration considers the requirements of all simultaneously connected network slices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single control plane configuration is used for all network slices, then device complexity is reduced, but network slice performance deteriorates due to inability to meet diverse requirements
Solution Approach 1:
The patent segments the control plane configuration into slice-specific configurations. Instead of using a single unified configuration for all network slices, the system creates separate control plane configurations for each network slice, allowing each slice to have optimized parameters tailored to its specific requirements while maintaining overall system manageability through automated generation processes.
2Reliability
If control plane configurations are optimized for specific network slice requirements, then network slice performance is improved, but resource consumption increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting control plane configuration parameters based on network slice requirements. The system modifies parameters such as paging configurations, mobility settings, and other control plane parameters to match the specific needs of each network slice, thereby optimizing performance while managing resource consumption through targeted parameter adjustment rather than blanket optimization.
3Ease of operation
If predefined policies are used for control plane setup, then ease of operation is improved, but manufacturing precision deteriorates due to inability to generate accurate configurations
Solution Approach 1:
The patent implements feedback mechanisms where the system generates control plane configurations based on actual network slice requirements and UE capabilities. The configuration generation process incorporates feedback loops that adjust parameters based on network conditions and slice-specific needs, thereby achieving accurate configurations while maintaining ease of operation through automated policy-based generation.

AI summary
A method by a core network entity in a wireless communication system includes receiving, from an access and mobility management function (AMF), a request for a control plane configuration for a user equipment (UE), generating the control plane configuration for the UE based on the received request for the control plane configuration, and transmitting, to the AMF, the generated control plane configuration.
