5G UE Slice Selection Using Deployment-Aware Network Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, user equipment (UE) cannot select suitable network slices, leading to access and business service delays.
Innovation Solution
A slice selection method and terminal device that enables UE to receive deployment-related slice information, allowing it to select a suitable slice based on this information, including considerations of location, frequency, service, and operator identification, and prioritize slices using priority and weight information.

1Loss of time
If the network selects slices based on UE reports, then the network can manage slices centrally, but the UE experiences access and business service delays
Solution Approach 1:
The patent enables the UE to autonomously select network slices by providing it with deployment-related slice information (including slice identifiers, frequency points, and deployment locations) and allowing it to independently determine the most suitable slice based on its current location and service requirements, without requiring network mediation for each selection decision
Solution Approach 2:
The patent performs preliminary actions by pre-configuring the UE with deployment-related slice information before the UE needs to access the network, including slice identifiers, frequency points, and deployment locations, so that the UE can immediately select an appropriate slice without waiting for network responses during access attempts

AI summary
The present application relates to a slice selection method, and a terminal device. The method includes the terminal device receives deployment-related slice information; and the terminal device selects a slice based on the deployment-related slice information. In an embodiment of the present application, based on the deployment-related slice information, an preferred slice can be selected, which reduces access and business service delay for the terminal device.
