MUSIM UE Paging Collision Detection and DRX Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, collisions between paging occasions from different Universal Subscriber Identity Modules (USIMs) and time-critical information broadcasts can lead to interrupted or degraded communications, as existing technologies lack standard mechanisms to handle these collisions effectively.
Innovation Solution
A Multi-Universal Subscriber Identity Module (MUSIM) User Equipment (UE) is designed to receive and detect collisions between paging cycles and time-critical information broadcasts from multiple network entities, allowing it to tune radio frequency circuitry to prioritize reception of critical messages by determining optimal time slots within radio frames and adjusting Discontinuous Reception (DRX) cycle lengths to prevent missed communications.

1Reliability
If the UE monitors paging occasions from multiple network entities simultaneously, then the UE can receive paging information from both networks, but collisions between paging occasions and time-critical information broadcasts cause interrupted or degraded communications
Solution Approach 1:
The UE performs preliminary detection of paging occasion parameters and time-critical information parameters from multiple network entities before actual communication occurs. By calculating and comparing timing parameters in advance, the UE can identify potential collisions and adjust its reception schedule proactively, preventing communication interruptions rather than reacting to them after they occur.
Solution Approach 2:
The UE dynamically adjusts its reception timing and DRX cycle configurations based on detected collisions between paging occasions and time-critical information broadcasts. The system adapts its monitoring schedule in real-time, shifting paging occasion timings or modifying DRX parameters to avoid overlapping with time-critical information from other networks, thereby maintaining reliable communication despite multi-network operations.
2Reliability
If the UE adjusts DRX cycle lengths to avoid collisions, then the UE can prioritize critical messages, but the complexity of managing multiple paging cycle configurations increases
Solution Approach 1:
The UE segments the management of paging cycles by maintaining separate configuration sets for each network entity independently. Each network's paging parameters (drx-PagingCycle, nB, TPF) are stored and processed as distinct groups, allowing the UE to manage multiple configurations without creating a combinatorial explosion of complexity. This modular approach enables independent adjustment of each network's paging schedule to avoid collisions.
Solution Approach 2:
The UE implements a feedback mechanism that continuously monitors for collisions between paging occasions and time-critical information broadcasts from multiple networks. When collisions are detected, the system adjusts DRX cycle lengths and paging timing parameters accordingly, then verifies whether the adjustment resolved the collision. This closed-loop feedback approach automates the complexity of multi-configuratio
