Cell Reselection Frequency Priority for Network Slice Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cell reselection mechanisms in wireless communication technology do not effectively prioritize frequencies for user equipment (UE) to access the most suitable cell with the highest signal quality and preferred network slice frequency, leading to suboptimal network slice service access.
Innovation Solution
The method involves the UE receiving base station signaling that includes frequency information of a preferred frequency of a network slice, allowing it to determine the frequency priority for cell reselection, thereby increasing the likelihood of accessing the intended network slice with higher quality service.

Engineering Contradiction Analysis
1Reliability
If the UE uses traditional cell reselection mechanisms without frequency priority information, then the cell reselection process is simple, but the UE cannot access the preferred network slice frequency with higher priority, leading to suboptimal network slice service access
Solution Approach 1:
The base station performs preliminary action by determining and signaling frequency priority information for network slices before the UE performs cell reselection. The network configures and sends frequency priority indications to the UE in advance, enabling the UE to prioritize frequencies associated with preferred network slices during the reselection process, thereby improving access reliability without adding complex real-time decision mechanisms
Solution Approach 2:
The frequency priority information is segmented and organized by network slice identifiers. Each network slice has its associated frequency priorities independently configured and signaled, allowing the UE to process and apply priority information for different slices separately, which maintains system simplicity while enabling reliable slice-specific frequency selection
2Reliability
If the base station sends frequency priority information for network slices, then the UE can determine frequency priority for cell reselection and access preferred network slices with higher quality service, but the signaling overhead increases
Solution Approach 1:
The frequency priority information for network slices is merged with existing cell reselection signaling structures. The priority information is combined with frequency measurements and cell reselection criteria that the UE already processes, rather than creating separate dedicated signaling messages. This integration approach reduces overall signaling overhead while still conveying the necessary frequency priority information for preferred network slice access
Solution Approach 2:
The frequency priority information signaling mechanism is designed to serve multiple functions: it guides cell reselection frequency selection, supports network slice prioritization, and integrates with existing measurement reporting structures. This multi-functionality allows a single signaling mechanism to achieve multiple objectives, reducing the need for additional dedicated signaling and thereby minimizing overhead while improving access reliability
