Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current User Equipment (UE) lacks standardized behavior for handling multiple universal subscriber identity modules (USIMs), leading to inefficiencies in resource allocation and potential collisions during paging and random access procedures.
Innovation Solution
A method and UE design that allow for dynamic registration of multiple SIMs with different network entities, configuration of RF resources, and intelligent provisioning based on priority and availability, ensuring optimal resource allocation and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SIMs are registered with different network entities, then connectivity and service coverage are improved, but resource allocation complexity and collision risk increase
Solution Approach 1:
The patent implements dynamic RF resource allocation where the UE can switch RF resources between different SIMs based on real-time needs. The system dynamically determines whether to retain or release RF resources for ongoing procedures like random access, and whether to tune away to monitor paging on other SIMs, creating an adaptive resource management system that responds to changing communication requirements.
Solution Approach 2:
The UE autonomously manages its own RF resources without requiring external coordination. The device independently determines priority of ongoing procedures versus paging monitoring, self-regulates RF resource retention or release, and automatically handles resource reallocation when switching between SIMs, reducing the need for complex network-side resource coordination.
2Reliability
If RF resources are retained for ongoing random access procedure, then access reliability is improved, but paging monitoring on other SIMs is delayed
Solution Approach 1:
The system dynamically adjusts RF resource allocation based on the state of ongoing procedures. When a random access procedure is active, the UE can choose to retain RF resources to ensure completion, but this decision is flexible and can be changed based on priority assessments. The system allows dynamic switching between retaining resources for reliability versus releasing them for timely paging monitoring on other SIMs.
Solution Approach 2:
The patent changes the operational parameters of RF resource management by introducing priority-based decision-making. The UE evaluates the priority of ongoing procedures against the importance of paging monitoring, and adjusts resource allocation parameters accordingly. This parameter-based approach allows the system to adapt resource retention duration and timing based on service requirements.
3Productivity
If RF resources are released for second SIM, then resource utilization efficiency is improved, but ongoing procedure on first SIM may fail
Solution Approach 1:
The UE performs preliminary assessment of ongoing procedures before releasing RF resources. The system evaluates whether procedures are in critical phases that would fail if resources are released, and makes informed decisions about resource reallocation timing. This preliminary evaluation prevents premature resource release that would cause procedure failures while still enabling efficient resource utilization when safe to do so.
Solution Approach 2:
The system implements feedback mechanisms where the UE monitors the state of ongoing procedures and adjusts resource allocation based on procedure progress. The feedback loop allows the UE to detect when procedures are nearing completion or are resilient to resource release, enabling safe reallocation of RF resources to other SIMs while maintaining procedure reliability through continuous state monitoring.
