NG-RAN Node Configuration Without Network Slice Support List
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current 5G system architecture requires setting network slice support lists during base station deployment, limiting flexibility in application scenarios, and potentially leading to incorrect or unsupported configurations that prevent base stations from providing required services.
Innovation Solution
A non-network-slicing-based configuration method where the NG-RAN node does not include a network slice support list in the next-generation setup request message sent to the AMF node, allowing for increased flexibility in RAN node deployment and simplified parameter settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the NG-RAN node includes a network slice support list in the NG SETUP REQUEST message, then the network slice configuration is complete and standardized, but the flexibility in deployment is reduced and the complexity of parameter settings increases
Solution Approach 1:
The patent extracts the network slice support list from the NG SETUP REQUEST message, separating this configuration element from the mandatory message structure. This allows the NG-RAN node to operate without pre-configuring network slice information, thereby improving deployment flexibility while maintaining network slice functionality through alternative configuration methods.
Solution Approach 2:
The patent introduces dynamic configuration of network slice parameters by removing the static pre-configuration requirement. Instead of fixing the network slice support list during deployment, the system allows for dynamic assignment and configuration of network slice parameters during operation, enabling adaptive deployment scenarios.
2Reliability
If the NG-RAN node includes a network slice support list in the NG SETUP REQUEST message, then the configuration follows 3GPP standards, but the number of parameters to be set increases and the configuration process becomes more complex
Solution Approach 1:
The patent removes the network slice support list from the NG SETUP REQUEST message structure, reducing the number of mandatory parameters that need to be configured. This extraction simplifies the configuration process while maintaining standard compliance through alternative mechanisms for network slice information exchange.
Solution Approach 2:
The patent applies local quality by configuring network slice parameters only where specifically needed rather than requiring universal pre-configuration across all NG-RAN nodes. This allows for selective configuration based on actual deployment requirements, reducing overall system complexity.
3Stability of the object's composition
If the base station pre-configures the network slice support list during deployment, then the configuration is consistent with network requirements, but the ability to adapt to different application scenarios is reduced
Solution Approach 1:
The patent transforms the static pre-configuration model into a dynamic configuration approach. Network slice parameters are no longer fixed during deployment but can be dynamically assigned and modified based on actual application scenarios, enabling the base station to adapt to diverse service requirements while maintaining configuration consistency through centralized control.
Solution Approach 2:
The patent makes the NG-RAN node universal by removing scenario-specific pre-configuration requirements. The base station can now serve multiple different application scenarios without requiring separate configurations for each scenario, achieving multi-functionality through a unified configuration approach.

AI summary
A non-network-slicing-based configuration method is provided. The method includes generating, by a next-generation radio access network (NG-RAN) node, a next-generation setup request message, wherein the next-generation setup request message does not include a first network slice support list supported by the NG-RAN node. The method includes transmitting, by the NG-RAN node, the next-generation setup request message to an access and mobility management function (AMF) node in a core network.
