UE Cell Selection via Transmission Link Parameter Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) may experience poor communication quality due to a transmission link allocated by the network side not supporting the requirements of the current service scenario, leading to issues like long delays and high packet loss rates, even when the signal quality of the serving cell is high.
Innovation Solution
The UE acquires parameter values of the allocated transmission link, such as resource quantity and quality of service (QoS), and triggers cell selection if these parameters do not meet the service requirements, allowing it to switch to a more suitable cell for improved communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the UE stays in the present serving cell based on high signal quality, then the signal strength is maintained, but the communication quality deteriorates due to poor transmission link parameters
Solution Approach 1:
The patent applies parameter changes by evaluating multiple transmission link parameters (SNR, packet loss rate, delay, resource quantity, QoS) beyond just signal quality. The UE determines whether to trigger cell selection based on whether these parameters meet service scenario requirements, thereby changing the decision criterion from single-parameter signal quality to multi-parameter transmission link quality assessment.
2Reliability
If the UE triggers cell selection frequently to improve communication quality, then the transmission requirements are better met, but unnecessary cell selection occurs when signal quality is already sufficient
Solution Approach 1:
The patent changes the triggering condition parameter from simple signal quality threshold to a composite assessment of transmission link parameters including SNR, packet loss rate, delay, resource quantity, and QoS. This prevents unnecessary cell selection by requiring that transmission link parameters actually fail to meet service requirements before triggering cell selection.
Solution Approach 2:
The patent implements feedback by continuously monitoring transmission link parameters and comparing them against service scenario requirements. The cell selection triggering decision is based on this feedback loop that assesses whether current transmission parameters satisfy communication needs, avoiding unnecessary selections when parameters are adequate.
3Ease of operation
If the UE uses traditional signal quality-based cell selection, then the cell selection process is simple, but it fails to account for transmission link parameter mismatches with service requirements
Solution Approach 1:
The patent transforms the cell selection criterion from simple signal quality to a comprehensive set of transmission link parameters (SNR, packet loss rate, delay, resource quantity, QoS) that are explicitly tied to service scenario requirements. This enables the system to adapt to different service scenarios by evaluating whether allocated resources meet specific transmission needs.
Solution Approach 2:
The patent introduces dynamics by making the cell selection triggering condition adaptive to service scenarios. Different service scenarios have different transmission parameter requirements, and the UE dynamically adjusts its cell selection decision based on whether current transmission parameters match the specific service scenario needs, rather than using a fixed signal quality threshold.
