UICC Polling Skip for Wireless Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing power consumption, particularly for devices like UICCs in mobile equipment, where frequent polling events consume battery life without providing new information, especially in devices with non-rechargeable batteries and smaller capacities.
Innovation Solution
Implementing a method where a UICC is associated with a particular bit value indicating the skipping of polling events, aligned with a discontinuous reception (DRX) cycle, and configuring UICC features based on device categories to optimize power consumption, such as skipping every nth polling event or deactivating advanced features in devices like eMTC equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequent polling events are performed to check UICC status, then the reliability of communication is improved, but the battery life deteriorates
Solution Approach 1:
The patent implements discontinuous reception (DRX) cycles where polling events occur periodically rather than continuously. The network configures DRX parameters including on duration, inactivity timer, and DRX cycle length, allowing the UE to enter low-power states between polling events while maintaining communication reliability through periodic wake-ups.
Solution Approach 2:
The patent dynamically adjusts polling frequency based on communication activity. When data transmission occurs, the inactivity timer resets and polling frequency increases; when no activity is detected, the timer expires and polling frequency decreases, allowing the system to adapt between high-reliability and low-power modes.
2Adaptability or versatility
If advanced UICC features are activated for full functionality, then the versatility of the device is improved, but the power consumption increases
Solution Approach 1:
The patent enables selective activation of UICC features based on device category and communication requirements. Different UICC application sets (e.g., EF-AD, EF-PDS, EF-GID) are activated or deactivated according to the specific needs of eMTC versus legacy devices, allowing advanced features to be available when needed while remaining dormant to conserve power.
Solution Approach 2:
The patent changes operational parameters of UICC features based on device category. Configuration messages from the network specify which UICC applications should be active, allowing the system to optimize the balance between functionality and power consumption by adjusting feature activation states rather than maintaining fixed configurations.
3Ease of operation
If polling events are performed at fixed intervals regardless of activity, then the simplicity of operation is improved, but the loss of energy increases
Solution Approach 1:
The patent implements feedback mechanisms where the UE monitors data reception activity and provides implicit feedback through inactivity timer management. When data is received, the timer is reset; when no data is received for the timer duration, the UE transitions to lower-power polling intervals. This automatic feedback-driven adjustment eliminates energy waste without requiring complex manual configuration.

AI summary
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, an equipment, such as a mobile equipment or user equipment (ME/UE), may determine that a universal integrated circuit card (UICC) coupled to the equipment is associated with a particular bit value indicating to skip at least one polling event of a polling cycle; and/or skip the at least one polling event based at least in part on the particular bit value In some aspects, the equipment may provide category information indicating a device category of the equipment, wherein the category information is provided to a UICC of the equipment; and/or receive, from the UICC, configuration information that is based at least in part on the category information, wherein the configuration information relates to an operation associated with power consumption by the equipment. Numerous other aspects are provided.
