Compressed Mode Initiation via Network Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, the compressed mode cannot be effectively started during load balancing or service bearer feature mechanisms, leading to poor Quality of Service (QoS) and system performance due to inadequate information about load and bearer conditions between cells.
Innovation Solution
A method where a terminal receives information from a radio network controller to determine a transmission gap pattern sequence, allowing it to start a compressed mode for inter-carrier frequency and inter-system measurement, thereby optimizing the switching process and reducing the load on congested cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the terminal controls the start of compressed mode autonomously, then the switching speed is improved, but the QoS and system performance deteriorate due to lack of load and bearer information
Solution Approach 1:
The network controller provides feedback information about load conditions and service bearer features to the terminal. This feedback mechanism allows the terminal to make informed decisions about when to start compressed mode, balancing switching speed with QoS requirements by considering actual network conditions rather than acting autonomously without information.
2Productivity
If the compressed mode is started late and kept short, then the system capacity and user throughput are enhanced, but the measurement accuracy for target cell deteriorates
Solution Approach 1:
The network controller pre-configures the terminal with transmission gap pattern sequence information before the terminal needs to perform measurements. This preliminary provision of measurement parameters allows the terminal to quickly initiate compressed mode with accurate measurement configurations, achieving both fast switching and measurement accuracy by having the measurement framework ready in advance.
3Device complexity
If the terminal performs inter-carrier frequency measurement without compressed mode, then the device complexity is reduced, but the measurement capability deteriorates due to inability to tune to target frequency
Solution Approach 1:
The terminal dynamically switches between measurement modes based on service requirements. For services requiring inter-carrier frequency measurement, the terminal activates compressed mode to enable frequency tuning. For other services, the terminal operates without compressed mode, maintaining simple device architecture while adapting measurement capability to actual needs through dynamic configuration rather than permanent hardware complexity.
