Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless positioning technologies lack flexibility in the sending frequency for broadcast packets, which can lead to inefficient communication and positioning accuracy due to preset frequencies not adapting to changing channel environments.
Innovation Solution
A method and apparatus for a terminal to dynamically adjust the broadcast packet sending frequency based on channel environment parameters such as packet time density and/or packet sending success rate, allowing for adaptive frequency adjustment in response to changing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a preset sending frequency is used for broadcast packets, then the system operation is simple, but the adaptability to changing channel environments deteriorates
Solution Approach 1:
The patent implements dynamic adjustment of the sending frequency based on real-time channel environment parameters. The terminal device monitors packet time density and packet sending success rate, then adaptively adjusts the sending frequency within a preset range, transforming the static preset frequency into a dynamic parameter that responds to environmental changes.
Solution Approach 2:
The patent establishes a feedback mechanism where the terminal device continuously monitors channel environment parameters (packet time density and packet sending success rate) and uses this feedback to adjust the sending frequency. The adjustment follows a predetermined strategy based on the monitored parameters, creating a closed-loop control system that improves adaptability while maintaining operational simplicity.
2Measurement precision
If the sending frequency is increased, then the positioning accuracy is improved, but the energy consumption increases
Solution Approach 1:
The patent dynamically adjusts the sending frequency based on real-time channel conditions rather than using a fixed high frequency. When channel conditions are good (high packet sending success rate), the frequency can be reduced to save energy. When positioning accuracy requirements are high or channel conditions are poor, the frequency is increased accordingly, optimizing the balance between accuracy and energy consumption.
Solution Approach 2:
The patent changes the sending frequency parameter adaptively based on monitored channel environment parameters. By adjusting this key parameter within a preset range according to packet time density and packet sending success rate, the system optimizes the trade-off between positioning accuracy (which benefits from higher frequency) and energy consumption (which increases with higher frequency).

AI summary
Embodiments of the present invention provide a method and an apparatus for controlling a broadcast packet sending frequency, and a terminal, and relate to the field of wireless positioning technologies. The method includes: receiving, in at least one broadcast receiving period, a broadcast packet sent by another terminal; determining, according to the broadcast packet sent by the another terminal, a channel environment parameter of an area in which the terminal is located, where the channel environment parameter includes packet time density and/or a packet sending success rate; and determining, according to the channel environment parameter, a sending frequency for sending a broadcast packet in a broadcast sending period after the at least one broadcast receiving period by the terminal. Therefore, the problem described in the background part that the sending frequency for sending a broadcast packet by the terminal lacks flexibility is resolved, the sending frequency is adaptively adjusted according to the channel environment parameter, and broadcast packet sending flexibility is improved.
