UE Measurement Reporting Adaptation to Moving Speed
Solution Overview
Problem
In LTE mobile communication systems, user equipment (UE) experiences delays in reporting measurement results due to predetermined DRX cycles, which can affect communication continuity, especially at varying moving speeds.
Innovation Solution
The UE determines its moving speed state by counting cell switches over a given period and adjusts its measurement period accordingly using pre-configured or base-station-provided speed parameters, ensuring timely and accurate reporting of measurement results to the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the UE uses a predetermined DRX cycle for measurement reporting, then power consumption is reduced through discontinuous reception, but measurement result reporting becomes delayed especially at high moving speeds
Solution Approach 1:
The patent applies dynamics by making the measurement period configurable and adaptable based on UE moving speed. The network can dynamically adjust the measurement period parameter according to the UE's speed state, allowing the system to transition from a static predetermined DRX cycle to a dynamic measurement period that adapts to changing conditions, thereby resolving the contradiction between power saving and timely reporting.
Solution Approach 2:
The patent changes the measurement period parameter based on the UE's moving speed state. When the UE is detected to be moving at high speed, the measurement period is reduced to enable more frequent reporting. This parameter adjustment resolves the contradiction by allowing the system to maintain longer measurement periods (saving power) during low-speed operation while switching to shorter periods (reducing delay) during high-speed operation.
2Use of energy by moving object
If the measurement period is extended to save power, then energy consumption decreases, but the timeliness of measurement result reporting deteriorates
Solution Approach 1:
The system dynamically adjusts the measurement period based on the UE's moving speed state rather than using a fixed extended period. This allows the measurement period to be longer (saving energy) during low-speed operation while being shorter (maintaining reliability) during high-speed operation, thus resolving the contradiction between energy saving and communication continuity.
Solution Approach 2:
The measurement period parameter is changed according to the UE's speed state. The network configures different measurement period values based on whether the UE is in low-speed or high-speed state, allowing the system to optimize between energy consumption and reporting timeliness根据不同场景，resolving the contradiction between energy saving and reliability.
3Reliability
If the UE reports measurement results frequently to ensure timeliness, then communication continuity is maintained, but power consumption increases due to continuous monitoring
Solution Approach 1:
The patent changes the measurement period parameter based on the UE's moving speed state. Instead of using a fixed short measurement period that would consume excessive power, the system uses longer periods during low-speed operation (reducing power consumption) and shorter periods during high-speed operation (maintaining communication continuity), thus resolving the contradiction.
Solution Approach 2:
The measurement period is made dynamic and adaptable to the UE's operating conditions. The system transitions from continuous frequent reporting (high power consumption) to conditional reporting based on speed state, allowing the UE to conserve power during stable low-speed operation while ensuring timely reporting during high-speed movement when communication continuity is more critical.
