Location Service Control With Valid-Time Privacy Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current location services result in wastage of transmission resources and power consumption due to frequent rejection of network requests for obtaining terminal location by users who do not want to disclose their location, leading to inefficient signaling and power usage.
Innovation Solution
Implementing a method for location service control that includes transmitting and receiving information related to a valid time and control information to manage the behavior of obtaining terminal location, thereby reducing unnecessary location updates and privacy verifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal frequently rejects network requests for obtaining location to protect user privacy, then location privacy protection is improved, but transmission resources and power consumption are wasted
Solution Approach 1:
The network side performs preliminary location measurement and obtains location information before the terminal needs to reject requests. The location data is cached and prepared in advance, so when location services are needed, the terminal can provide location without actively measuring or transmitting location data, thus avoiding repeated power-consuming operations while maintaining privacy control
Solution Approach 2:
The network side acts as an intermediary that performs location measurement and caching functions. Instead of the terminal repeatedly measuring and transmitting location data (which consumes power), the network side intermediates by obtaining location information through alternative means and making it available when needed, reducing the terminal's power consumption while maintaining location service functionality
2Reliability
If the terminal frequently rejects network requests for obtaining location to protect user privacy, then location privacy protection is improved, but transmission resources are wasted
Solution Approach 1:
Location information is measured and cached in advance by the network side or terminal before actual location service requests occur. This preliminary action ensures that location data is ready when needed, eliminating the need for frequent repeated transmission requests and reducing signaling overhead
Solution Approach 2:
The location information is copied and cached in multiple locations (network side and terminal). Instead of the terminal repeatedly generating and transmitting original location data through active measurement, cached copies are used to fulfill location service requests, reducing transmission resource consumption while maintaining data availability
3Productivity
If location information is cached on the network side for a duration, then location service efficiency is improved, but the cached location information may become outdated
Solution Approach 1:
The caching duration is not fixed but dynamically adjusted based on terminal movement state. When the terminal is detected to be stationary, the caching duration is extended to improve efficiency. When movement is detected, the caching duration is reduced or invalidated to maintain location accuracy, thus dynamically balancing efficiency and accuracy based on actual conditions
Solution Approach 2:
The system uses feedback from terminal movement detection to adjust caching behavior. The network side monitors terminal state and provides feedback on whether cached location information remains valid. This feedback mechanism ensures that location accuracy is maintained by invalidating caches when terminal movement occurs, while still allowing extended caching during stationary periods to improve efficiency
