Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in next-generation mobile communication systems is to improve the performance of terminals and base stations and provide slices quickly.
Innovation Solution
A method and device that involve storing and transmitting slice-based measurement information during cell reselection in the RRC idle or inactive state, allowing terminals to receive configuration information for supporting slices from base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the terminal performs slice-based cell reselection in RRC idle or inactive state and transmits measurement information to the base station, then the slice provisioning speed is improved, but the terminal's power consumption and processing complexity increase
Solution Approach 1:
The terminal performs measurement and stores slice-based measurement information during cell reselection in RRC idle or inactive state before actual slice provisioning is needed. This preliminary action allows the base station to quickly retrieve and use this pre-collected information when the terminal transitions to RRC connected state, thereby reducing slice provisioning time without requiring complex real-time processing.
2Manufacturing precision
If the base station retrieves and processes measurement information from multiple terminals, then slice provisioning accuracy is improved, but the base station's processing load increases
Solution Approach 1:
The base station extracts only the necessary slice-based measurement information from terminal reports that is relevant for slice provisioning decisions. Rather than processing all measurement data from terminals, the base station selectively retrieves and uses only the critical information needed for accurate slice configuration, thereby reducing processing load while maintaining provisioning accuracy.
3Productivity
If the terminal stores measurement information in RRC idle or inactive state, then slice provisioning efficiency is improved, but the terminal's memory requirements and information management complexity increase
Solution Approach 1:
The terminal stores measurement information with specific quality characteristics tailored for slice provisioning purposes. Rather than storing all possible measurement data, the terminal selectively stores only the relevant slice-based measurement information (such as RSRP, RSRQ, and other slice-related parameters) in RRC idle or inactive state. This localized quality approach improves slice provisioning efficiency while minimizing memory requirements and information management complexity.

AI summary
The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. The present disclosure relates to a method performed by a terminal in a wireless communication system, and a device for performing same, wherein the method comprises the steps of: storing measurement information obtained through slice-based cell reselection in a radio resource control (RRC) standby state or RRC inactive state; transmitting the measurement information obtained through the slice-based cell reselection to a base station after the terminal switches to an RRC connected state; and receiving, from the base station, information for configuring a cell supporting a slice for the terminal on the basis of the measurement information obtained through the slice-based cell reselection.
