LOCATION LOGGING AND LOCATION AND TIME BASED FILTERING

摘要

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.

1. A method for use in obtaining information about a location of a terminal, the method comprising, at the terminal:
determining a location of the terminal at different times and during paging slots in which the terminal detects for pages from a wireless network; determining whether the location of the terminal as determined at a second time of the different times is different from the location of the terminal as determined at a first time of the different times, the second time being subsequent the first time; and in response to a determination that the location of the terminal as determined at the second time is different from the location of the terminal as determined at the first time, storing information associated with the location of the terminal as determined at the second time.
