Beacon-Based Base Station Change Detection for Lower Terminal Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent updating of base stations based on GPS latitude and longitude information in LoRaWAN beacons leads to unnecessary power consumption and reduced battery life in terminals.
Innovation Solution
Utilizing a combination of geographic location information and received signal strength information to determine if beacon frames are issued by the same base station, reducing the need for unnecessary updates by comparing parameter changes between frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal updates the route every time GPS latitude and longitude information in Beacons changes, then the route accuracy is improved, but the power consumption increases and battery life is reduced
Solution Approach 1:
The patent changes the parameter for base station identification from GPS latitude and longitude information to base station identifier information. This parameter change eliminates the problem of slight variations in GPS information causing unnecessary route updates, thereby reducing power consumption while maintaining route accuracy through more stable identification criteria.
2Reliability
If the terminal actively reports data packets whenever GPS information changes, then the network server can update the route accurately, but the terminal's battery life is greatly reduced
Solution Approach 1:
The patent changes the triggering parameter for active reporting from GPS information changes to base station identifier changes. Since base station identifiers are more stable and less prone to slight variations, this reduces the frequency of unnecessary active reports while ensuring reliable route updates only when actual base station changes occur, thus extending battery life.
3Loss of information
If the terminal uses GPS latitude and longitude information to identify base stations, then the terminal can acquire base station location data, but the determination accuracy is reduced due to slight variations in GPS information
Solution Approach 1:
The patent changes the identification parameter from GPS latitude and longitude information to base station identifier information. Base station identifiers provide more precise and consistent identification without the slight variations inherent in GPS data, thereby improving base station determination accuracy and reducing information loss.

AI summary
The present disclosure proposes a method, an apparatus, a device, and a storage medium for communication between a terminal and a base station. A first beacon frame sent by a first base station is received, wherein the first beacon frame includes first location information, and the first location information is used to characterize a location of the first base station; and in the case where a distance between the first location information and second location information is greater than a first predetermined threshold or where a difference between first received signal strength information and second received signal strength information is greater than a second predetermined threshold, first information is sent to a network server, which is used to cause the network server to update a base station corresponding to downlink data of the terminal based on the first information. In this way, the accuracy of determination can be improved, and the power consumption of the terminal can be saved. For example, the battery consumption of the terminal can be greatly reduced, and the battery life of the terminal can be improved.
