Continuous MDT Measurement Across UE RRC State Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MDT technologies only perform measurements when a UE is in an idle state and do not support continuous measurements across idle, inactive, and connected states, limiting network optimization functions such as position prediction and AI training.
Innovation Solution
A method and apparatus enabling continuous MDT measurements across idle, inactive, and connected states in User Equipment (UE), allowing for the collection of continuous historical position data for improved position prediction and network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MDT measurement is performed only in idle state, then device complexity is reduced, but measurement precision and continuity are insufficient for network optimization
Solution Approach 1:
The patent implements dynamic measurement configuration that adapts to different RRC states. The network side dynamically configures measurement parameters based on whether the UE is in idle, inactive, or connected state, enabling continuous measurement across state transitions without requiring complex device-side decision logic. This resolves the contradiction by making the measurement system dynamic rather than static.
Solution Approach 2:
The patent creates a universal measurement framework that operates across all RRC states (idle, inactive, connected). The same measurement mechanism and reporting structure are used regardless of state, with the network side adapting configuration parameters. This multi-functional approach enables continuous measurement without requiring separate complex systems for each state.
2Loss of information
If MDT measurement is performed only in idle state, then use of energy is reduced, but loss of information occurs due to discontinuous measurement
Solution Approach 1:
The patent establishes continuous measurement action across all RRC states by having the UE perform measurements in idle, inactive, and connected states. The measurement process continues uninterrupted through state transitions, with the network side coordinating configuration and reporting. This eliminates information loss from discontinuous measurement while managing energy consumption through efficient reporting mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms where the network side receives measurement reports from the UE and uses this information to optimize network configuration and performance. The continuous feedback loop across different states ensures that measurement information is captured and utilized effectively, preventing information loss while enabling energy-efficient operation through intelligent network control.
3Productivity
If MDT measurement is performed only in idle state, then ease of operation is maintained, but productivity of network optimization functions is reduced
Solution Approach 1:
The patent introduces the network side as an intermediary that manages the complexity of continuous measurement across states. The network side handles configuration, state tracking, and report collection, shielding the UE from complex operational decisions. This intermediary approach enables high-productivity continuous measurement while maintaining ease of operation at the device level through simplified local execution of network-provided instructions.
