Dynamic UE Category Switching for Connected Car Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators face challenges in effectively servicing diverse and increasing numbers of non-traditional device types, such as M2M and IoT devices, due to their varying characteristics and requirements, which existing UE categories fail to adequately address.
Innovation Solution
A connected car device dynamically switches between available UE categories based on its operational mode, application communication requirements, and mobility state, allowing it to select the most appropriate category from a set of available categories, such as 3GPP categories 0 to 12, to optimize communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single UE category is used for all devices, then device complexity is reduced, but adaptability to diverse device requirements deteriorates
Solution Approach 1:
The patent implements dynamic UE category switching where the connected car device can transition between different UE categories based on its operational state (idle vs. connected mode). This dynamic adaptation allows the system to optimize communication parameters for diverse device requirements without requiring complex static categorization for all possible scenarios.
Solution Approach 2:
The patent changes key communication parameters (UE category) based on the device's operational mode and mobility state. By adjusting the UE category parameter dynamically, the system adapts to diverse device requirements while maintaining manageable complexity through standardized parameter switching mechanisms.
2Reliability
If highest UE category is always selected, then communication performance is improved, but energy consumption increases
Solution Approach 1:
The patent applies partial action by selecting the appropriate UE category level based on actual needs. Instead of always using the highest category, the device selects the minimum necessary category for the current operational mode, consuming energy only at the level required for effective communication.
Solution Approach 2:
The patent dynamically adjusts the UE category based on operational mode and mobility state, allowing the communication performance and energy consumption to be optimized in real-time according to actual device needs rather than using a fixed high-performance configuration.
3Adaptability or versatility
If UE category is frequently switched, then adaptability to changing conditions is improved, but system stability deteriorates
Solution Approach 1:
The patent implements periodic evaluation of operational mode and mobility state to determine when UE category switching is appropriate. By using structured triggers (mode changes, mobility state changes) rather than continuous switching, the system maintains stability while still adapting to changing conditions.
Solution Approach 2:
The patent uses feedback from the device's operational state and mobility measurements to guide UE category selection. This feedback mechanism ensures switching occurs only when genuinely needed, maintaining system stability while providing adaptability to changing conditions.
