MUSIM UE Paging Pattern Coordination for Message-Service Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G networks face challenges in managing message services on multiple universal subscriber identification module (MUSIM) user equipment (UE) with multiple USIMs, particularly in coordinating paging patterns to avoid collisions and optimize communication services based on priority and network policies.
Innovation Solution
A method for managing message services on MUSIM UE involves calculating time occasions and determining paging patterns based on priority-based rankings, associating criticality of communication services, and configuring policies to optimize network access, with support from policy control functions and network access nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple paging patterns are determined for multiple USIMs, then message service management efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the paging management by creating separate paging patterns for each USIM card. The UE determines a first paging pattern for a first USIM and a second paging pattern for a second USIM, allowing independent management of paging occasions for each subscription. This segmentation enables efficient handling of multiple message services while maintaining organized control structures within the device.
2Productivity
If priority-based rankings are associated with message services, then communication service optimization is improved, but measurement precision requirements increase
Solution Approach 1:
The patent introduces priority-based rankings as a parameter to characterize message services. Each message service is assigned a priority level (e.g., high, medium, low) based on its criticality. This parameter change enables the UE to optimize communication services by processing higher priority messages first and making informed decisions about paging pattern selection and resource allocation based on service criticality levels.
3Reliability
If paging patterns are coordinated to avoid collisions, then reliability of message delivery is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by determining and configuring paging patterns before message delivery collisions can occur. The UE calculates paging occasions for multiple USIMs, identifies potential collisions in advance, and selects or adjusts paging patterns proactively to avoid these collisions. This preliminary coordination ensures reliable message delivery without requiring complex real-time conflict resolution mechanisms.
4Productivity
If network assistance is provided for paging pattern determination, then message service management effectiveness is improved, but network communication overhead increases
Solution Approach 1:
The patent implements a self-service approach where the UE autonomously determines its own paging patterns based on its capabilities, multiple USIM configurations, and detected collision patterns. The device independently calculates paging occasions, selects appropriate paging patterns, and manages its message services without requiring continuous network assistance. This reduces network communication overhead while maintaining effective message service management.

AI summary
A method for managing message services on a multiple universal subscriber identification module (MUSIM) user equipment (UE) having at least a first USIM and a second USIM includes calculating a first time occasion that message services related to the first USIM are used, and a second time occasion that the message services related to the second USIM are used; determining a first paging pattern based on the first time occasion and a second paging pattern based on the second time occasion; transmitting, to a network access node, the first paging pattern and the second paging pattern; and receiving, from the network access node, a message indicating acceptance or rejection of the first paging pattern, and acceptance or rejection of the second paging pattern.
