Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single set of DRX parameters is preconfigured for the terminal, then the terminal can operate with simple parameter management, but the system cannot support large data traffic growth, massive device connections, and diverse new services
Solution Approach 1:
The patent segments the single DRX parameter set into multiple parameter sets (first DRX parameter set and second DRX parameter set), each optimized for different service scenarios. The terminal can select appropriate parameter sets based on service requirements, thereby supporting diverse services without overwhelming complexity
Solution Approach 2:
The patent introduces dynamic switching between different DRX parameter sets based on service status. The terminal determines whether to switch between the first and second DRX parameter sets according to service requirements, enabling adaptive parameter adjustment without manual intervention
2Duration of action of moving object
If the terminal uses a long DRX cycle, then battery usage time is prolonged, but the terminal responds more slowly when new data is transmitted
Solution Approach 1:
The patent enables dynamic switching between short and long DRX cycles based on service status. When data transmission is active, the terminal uses the short DRX cycle for fast response; when idle, it switches to the long DRX cycle to extend battery life, thus resolving the contradiction between response speed and power consumption
3Speed
If the terminal uses a short DRX cycle, then the terminal responds quickly when new data is transmitted, but battery usage time is reduced
Solution Approach 1:
The patent implements dynamic DRX cycle selection where the terminal switches between short and long cycles based on service status. The short cycle is activated during active data transmission for quick response, while the long cycle is used during idle periods to conserve battery, thereby resolving the trade-off between response speed and battery life
4Adaptability or versatility
If existing DRX parameters are used in LTE systems, then the system maintains backward compatibility, but it cannot meet requirements of larger data traffic, more device connections, and new services
Solution Approach 1:
The patent divides the DRX parameter configuration into multiple specialized parameter sets, with each set optimized for specific service requirements. This segmentation allows the system to handle diverse traffic types and device connections reliably while maintaining backward compatibility with existing LTE systems

AI summary
A discontinuous reception method, a terminal, and a network device are provided. The method includes: obtaining, by a terminal, discontinuous reception DRX parameter information corresponding to configuration parameter information supported by the terminal; and enabling DRX by using the obtained DRX parameter information. The method is applied to a communications system, the communications system supports N groups of configuration parameters, and each group of configuration parameters is corresponding to a group of discontinuous reception DRX parameters. A DRX parameter is corresponding to a configuration parameter, and the DRX parameter is adaptively and flexibly adjusted when the configuration parameter is flexibly adjusted based on a service in a network, so that the terminal is better balanced between a latency and power consumption, and the terminal can better adapt to a communications network with a larger system capacity, a lower latency, higher network reliability, and better network availability.
