UE Paging Signal Conflict Resolution via Dynamic Time Slot Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, conflicts arise when user equipment (UE) receives overlapping paging signals from multiple networks, leading to insufficient service provision due to simultaneous signal reception.
Innovation Solution
A method where the UE performs registration with multiple networks, identifies overlapping monitoring time points, requests configuration updates from the networks, and updates its monitoring time points based on received configuration information to prevent conflicts, using IMSI, new TMSI, or new GUTI for paging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE monitors paging signals from multiple networks at the same time, then the UE can receive services from multiple networks, but conflicts occur between overlapping paging signals
Solution Approach 1:
The UE segments the paging monitoring process by separating monitoring time points for different networks. When overlapping is detected, the UE requests and applies separate monitoring time point configurations from each network, dividing the monitoring function into non-overlapping time slots for each network to eliminate conflicts
Solution Approach 2:
The monitoring time points are made dynamic rather than fixed. The UE can request updates to monitoring time points from networks and adjust its monitoring schedule based on received configuration information, allowing the system to adapt to overlapping conditions and maintain reliable service reception
2Ease of operation
If the UE uses fixed monitoring time points for multiple networks, then the monitoring process is simple, but service provision is insufficient during paging signal conflicts
Solution Approach 1:
The UE performs preliminary detection to identify overlapping monitoring time points before conflicts occur. When overlap is detected, the UE proactively requests updated monitoring time point configurations from the networks, preventing service disruption before it happens
Solution Approach 2:
The system implements feedback mechanisms where the UE monitors for overlapping conditions and communicates with networks to request configuration updates. The networks respond with updated monitoring time point information, creating a closed-loop system that maintains both simplicity and service capability

AI summary
A method of receiving, by a user equipment (UE), a paging signal in a wireless communication system is disclosed. More specifically, the UE performs a registration to a plurality of networks, obtains a plurality of monitoring time points that has to check whether a paging message is received from each of the plurality of networks, when at least some of the plurality of monitoring time points overlap, transmits, to a first network, a change request of a first monitoring time point that has to check whether a first paging message is received from the first network of the plurality of networks, receives, from the first network, configuration information related to the request, and updates the first monitoring time point based on the configuration information.
