Radio Resource Configuration for Terminal Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The short standby time of terminal apparatuses due to high power consumption negatively impacts user experience, as they are burdened with numerous applications requiring continuous data transmission, leading to rapid battery depletion.
Innovation Solution
A method for establishing a radio connection between a network apparatus and a terminal apparatus, where power supplying state information is used to set a connection configuration instruction, optimizing the radio resource usage by reducing power consumption through controlled disconnecting times and sleep/monitoring ratios, thereby prolonging standby time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous data transmission is maintained to ensure network connectivity, then network connection reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic connection and disconnection of radio resources based on DRX (Discontinuous Reception) cycles. The terminal apparatus alternates between active monitoring periods and sleep periods, periodically waking up to check for downlink data while remaining connected to the network. This periodic action maintains network connectivity reliability while significantly reducing power consumption during sleep intervals compared to continuous transmission.
2Speed
If radio connection is maintained for network availability, then communication responsiveness is improved, but battery life is reduced
Solution Approach 1:
The patent dynamically adjusts the terminal's reception state between active and sleep modes based on downlink data arrival. When data is available, the terminal transitions to an active state for immediate communication. When no data is present, it transitions to a sleep state to conserve battery. This dynamic state adjustment maintains communication responsiveness when needed while extending battery life during idle periods.
Solution Approach 2:
The network apparatus sends wake-up indicators or downlink data notifications before the terminal needs to fully activate its radio resources. This preliminary action allows the terminal to prepare for communication in advance during wake-up periods, ensuring quick responsiveness when data arrives, while minimizing the duration of high-power states to extend battery life.
3Reliability
If frequent connection checks are performed to maintain network presence, then network connectivity is improved, but power consumption increases
Solution Approach 1:
The patent implements DRX (Discontinuous Reception) cycles where the terminal periodically checks for network data instead of continuously monitoring. During sleep periods, the terminal disconnects from active radio reception, and only wakes up at predetermined intervals to check for downlink data assignments. This periodic checking maintains network connectivity reliability while dramatically reducing power consumption compared to frequent or continuous connection checks.

AI summary
A method for establishing a radio connection between a network apparatus and a terminal apparatus, a network apparatus and a terminal apparatus are described. The method for establishing a radio connection, which is applied to a network apparatus, may include receiving a connection request for requesting a radio resource from a terminal apparatus, acquiring power supplying state information related to the terminal apparatus; setting a connection configuration instruction of the radio resource for connecting with the terminal apparatus based on the power supplying state information; and controlling a radio connection with the terminal apparatus based on the connection configuration instruction, the radio connection being used for data transmission between the network apparatus and the terminal apparatus. Accordingly, standby time of the terminal apparatus is prolonged while a network connection of the terminal apparatus can be maintained.
