Network Slice Selection via Radio Capability Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in determining which network slices to allow or reject for user equipment based on its radio capabilities, especially when slices operate in different frequency bands, leading to compatibility issues and inefficient network slice selection.
Innovation Solution
The method involves transmitting a request for user equipment radio capabilities from a core network function, receiving responses, and determining allowed or rejected network slices based on the equipment's capabilities, with configuration messages indicating compatibility, thereby enabling simultaneous use of compatible network slices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network allows multiple network slices to be used simultaneously by user equipment, then network service diversity and user experience are improved, but compatibility issues arise when slices operate in different frequency bands that the user equipment cannot support
Solution Approach 1:
The patent applies preliminary action by having the core network function proactively determine the user equipment's radio capabilities (including supported frequency bands) before allocating network slices. The network receives a capability indication from the UE, determines compatible network slices based on these capabilities, and provides configuration information to the UE in advance, preventing incompatibility issues before they occur.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting network slice allocation based on the user equipment's radio capability parameters. The core network function modifies the set of allowed network slices according to the detected frequency band capabilities of the UE, ensuring that only slices compatible with the UE's parameters are activated.
2Measurement precision
If the network determines radio capabilities for each user equipment individually, then accurate network slice selection is achieved, but network signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies self-service by having the user equipment autonomously determine and report its own radio capabilities to the network. The UE includes a capability indication in its communication with the core network function, eliminating the need for the network to perform complex capability measurements and reducing network processing complexity while maintaining accurate capability information.
