Mobile Station Ultra Power-Saving Mode DRX Cycle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile stations face high power consumption even when not providing telephone call services, as communication functions remain active in standby mode, preventing users from using supplementary services without significant power drain.
Innovation Solution
Implementing an ultra power-saving mode that inactivates communication functions and adjusts DRX cycle lengths to minimize power usage, allowing users to conserve battery life while still receiving text messages and call records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mobile station remains in standby mode to receive supplementary services, then service availability is improved, but power consumption increases because communication functions remain active
Solution Approach 1:
The patent implements a dynamic operation mode that allows the mobile station to switch between standby mode and ultra power-saving mode based on service requirements. The system dynamically adjusts the DRX cycle length coefficient (using Ni values from service profile) to optimize the balance between service availability and power consumption, rather than operating in a fixed standby state
Solution Approach 2:
The patent changes the DRX cycle length parameter by replacing the default coefficient 'k' with class-specific coefficients 'Ni' defined in the service profile. This parameter change extends the paging detecting cycle, reducing the frequency of communication function activations and thereby lowering power consumption while maintaining service availability
2Use of energy by moving object
If the mobile station powers off to save battery, then power consumption is reduced, but service accessibility is lost
Solution Approach 1:
The patent implements periodic monitoring of paging signals at extended intervals determined by the DRX cycle with coefficient Ni. This periodic action allows the mobile station to remain in a low-power state while still periodically checking for service notifications, ensuring service accessibility without continuous power consumption
Solution Approach 2:
The system dynamically adjusts between full power-off, ultra power-saving mode with extended DRX cycles, and normal standby mode based on service requirements, providing flexible service accessibility at different power consumption levels
3Use of energy by moving object
If the mobile station uses longer DRX cycle in standby mode, then power consumption is reduced, but service response time increases
Solution Approach 1:
The patent optimizes the DRX cycle length parameter by using class-specific coefficients Ni from the service profile, which are tailored to different service types. This parameter optimization achieves the longest possible DRX cycle for each service class, minimizing power consumption while maintaining acceptable response times for each service category
Solution Approach 2:
The patent applies different DRX cycle extensions for different service classes, using partial action (moderate extension for some services, extensive extension for others) based on service priorities defined in the service profile, rather than uniformly extending all DRX cycles

AI summary
Provided are a mobile station and a method for providing an ultra power-saving mode in a mobile station. The method for providing an ultra power-saving mode in a mobile station includes: inactivating a communication function in a standby mode of the mobile station; extracting a DRX (discontinuous reception) cycle length coefficient K of the mobile station; determining a class-specific DRX cycle length coefficient Ni of the mobile station; replacing K with Ni; and monitoring a paging signal at a paging cycle corresponding to Ni.
