Compact Paging Occasion Scheduling for Base Station Sleep
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paging frame and occasion distribution methods in communication systems do not facilitate energy-saving states for base stations, as they require continuous operation due to evenly distributed paging occasions across the entire cycle, even when serving a limited number of terminals.
Innovation Solution
Implementing a paging transmission method that selects or determines paging frames and occasions based on a preset strategy, including energy consumption states and formulas, to achieve compact transmission and allow base stations to enter sleep states more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging occasions are evenly distributed throughout the entire paging cycle according to UE ID, then paging services can be provided to all terminals, but the base station cannot enter deep sleep state and must remain powered on throughout the paging cycle
Solution Approach 1:
The patent segments the paging cycle into multiple paging frames, each containing multiple paging occasions. This segmentation allows the base station to concentrate paging operations within specific time windows rather than distributing them uniformly across the entire cycle, enabling the base station to enter sleep mode during non-paging periods and thus reducing energy consumption while maintaining reliable paging service availability.
2Use of energy by stationary object
If compact paging frame/occasion mode is adopted to reduce base station operation duration, then energy-saving state can be entered, but the method for achieving compact transmission has not been concluded
Solution Approach 1:
The patent changes the parameters of paging frame and occasion determination by introducing a preset strategy that includes energy consumption state information. This allows the base station to dynamically adjust paging transmission parameters based on current operational conditions, achieving compact transmission modes that enable energy-saving states while providing a clear, implementable method that reduces complexity compared to ad-hoc approaches.
3Productivity
If base station remains powered on throughout the paging cycle to provide paging services, then all terminals can be served, but the sleep duration of the base station is reduced
Solution Approach 1:
The patent implements periodic paging operations within the paging cycle, where paging occasions are concentrated in specific periodic intervals rather than continuously. This periodic action pattern allows the base station to remain powered on only during these brief periodic windows for paging transmission, while entering sleep mode during the rest of the cycle, thus extending sleep duration while maintaining comprehensive terminal coverage through repeated periodic cycles.

AI summary
A paging transmission method includes selecting or determining a paging frame and/or a paging occasion where the paging is located based on a preset strategy; and receiving the paging according to the paging frame and/or the paging occasion, thereby realizing compact transmission of the paging frame and/or the paging occasion, and reducing the duration of the base station or the cell in the energy-saving state for sending paging during the entire paging cycle, thereby ensuring the sleep duration of the base station or the cell in the energy-saving state.
