Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The small coverage area of existing base stations leads to high power consumption as they remain activated continuously, even when no user equipment is present, hindering traffic offloading and network throughput enhancement.
Innovation Solution
Implementing a power-saving state for wireless access points that includes intermittent receiving and transmitting patterns, allowing them to switch to a normal communication state upon user equipment activation, with user equipment sending activation signals based on configured patterns to conserve power and improve network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the micro cell is always in an enabled state to ensure timely service handover, then the reliability of service handover is improved, but the power consumption of the base station increases
Solution Approach 1:
The base station dynamically switches between wake-up patterns of different periods based on traffic conditions and handover requirements. When traffic is light, a longer wake-up period is used to save power; when traffic increases or handover activity is detected, the period is shortened to improve responsiveness. This dynamic adjustment resolves the contradiction between power saving and reliable service handover.
Solution Approach 2:
The system changes the wake-up pattern parameters (period, timing) based on operational conditions. The base station can adjust the wake-up interval and timing to optimize the balance between power consumption and service handover reliability, transitioning from a static always-enabled state to a dynamically parameter-adjusted state.
2Adaptability or versatility
If the micro cell is always in an enabled state to ensure coverage, then the availability of service is improved, but the power consumption increases when no user equipment is present
Solution Approach 1:
The base station operates in periodic wake-up cycles rather than continuously. It wakes up at predetermined intervals to check for user equipment and potential handover requests, then enters sleep mode between wake-up periods. This periodic operation maintains service availability when needed while dramatically reducing power consumption during idle periods with no user equipment present.
Solution Approach 2:
The base station autonomously monitors its own operational state and automatically adjusts its wake-up pattern based on detected traffic conditions and handover activity, eliminating the need for continuous external control signals while maintaining appropriate service availability.
3Speed
If the base station uses a shorter wake-up pattern period to improve responsiveness, then the speed of detecting user equipment is improved, but the power consumption increases
Solution Approach 1:
The base station dynamically adjusts the wake-up pattern period based on real-time conditions. When user equipment detection speed is critical (high traffic, handover activity), it uses shorter periods for faster detection. When traffic is light and responsiveness is less critical, it extends the period to save power, thus resolving the contradiction between detection speed and power consumption.

AI summary
The present invention provides a wireless access point control method, a related device, and a system. An activation signal sent by user equipment is received on a radio resource corresponding to a receiving pattern of a first wireless access point, so that the first wireless access point controls itself to leave a power-saving state according to the activation signal. Therefore, the user equipment may directly send the activation signal to the first wireless access point to switch a working state of the first wireless access point from the power-saving state to a normal communication state as soon as possible. In this manner, a power-saving objective of the wireless access point is achieved, and switching of the wireless access point from the power-saving state to the normal communication state as soon as possible can also be accelerated on a basis of achieving power saving of the wireless access point.
