Location Logging and Filtering for Wireless Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face the tedious task of manually filtering through various types of broadcast information, such as advertisements and news, to identify content of interest, which can be time-consuming and inefficient.
Innovation Solution
A method and apparatus that determine a terminal's location at different times during paging slots in a wireless network and store information associated with location changes, allowing for location and time-based filtering of broadcast information using metadata criteria to automatically prioritize and present relevant content to the user.

Engineering Contradiction Analysis
1Ease of operation
If manual filtering of broadcast information is used, then users can identify content of interest, but the process becomes tedious and time-consuming
Solution Approach 1:
The terminal automatically performs filtering of broadcast information using stored location and time criteria without requiring user intervention. The system monitors its own location, compares it against stored criteria, and autonomously determines which broadcast content to present to the user, eliminating the need for manual filtering while reducing time loss.
Solution Approach 2:
Location and time criteria are pre-stored in the terminal before broadcast information is received. This preliminary setup enables the terminal to automatically filter and select relevant broadcast content based on predetermined conditions, eliminating the need for users to manually filter content in real-time and significantly reducing the time required to identify interesting content.
2Measurement precision
If location determination is performed frequently to track terminal movement, then location accuracy improves, but energy consumption increases
Solution Approach 1:
The terminal determines its location periodically at predetermined intervals rather than continuously or at every paging slot. This periodic measurement approach maintains sufficient location accuracy for filtering broadcast information while significantly reducing the energy consumption associated with frequent location determinations and wireless communications.
Solution Approach 2:
The system changes the frequency parameter of location determination from continuous/high-frequency to periodic/lower-frequency based on the specific needs of the application. This parameter adjustment maintains adequate location precision for filtering purposes while optimizing energy consumption by reducing the number of location determination operations performed.

AI summary
Techniques for performing location logging and location and time based filtering are described. In one design of location logging, a terminal periodically determines its location, e.g., during its paging slots. The terminal determines whether there is a change in its location and stores its location if a change in location is detected. In one design of location and time based filtering, the terminal obtains a location and time criterion with a target area and a time period. The terminal determines its location during the time period, e.g., based on the location log. The terminal evaluates the location and time criterion based on the target area and its location during the time period, e.g., based on at least one sector ID for the target area and one or more sector IDs for its location. The terminal determines whether to download and/or present broadcast information based on the result of the evaluation.
