Location logging and location and time based filtering
First Claim
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 during a plurality of paging slots in which the terminal listens for pages from a wireless network, wherein the terminal is configured with the paging slots repeating periodically according to a paging cycle, and wherein determining the location of the terminal during the paging slots comprises determining the location of the terminal during a logging interval in which at least one location change is logged, the logging interval spanning multiple paging slots;
determining whether the location of the terminal as determined during a second paging slot is different from the location of the terminal as determined during a first paging slot, the second paging slot being subsequent to the first paging slot; and
in response to a determination that the location of the terminal as determined during the second paging slot is different from the location of the terminal as determined during the first paging slot, storing information associated with the location of the terminal as determined during the second paging slot.

Abstract
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.

9. A terminal comprising:
-
memory; a receiver; and a processor connected to the memory and the receiver, the processor being configured to; determine a location of the terminal during a plurality of paging slots in which the terminal listens for pages from a wireless network using the receiver, wherein the terminal is configured with the paging slots repeating periodically according to a paging cycle, and wherein the processor is configured to determine the location of the terminal during a logging interval in which at least one location change is logged, the logging interval spanning multiple paging slots; determine whether the location of the terminal as determined during a second paging slot is different from the location of the terminal as determined during a first paging slot, the second paging slot being subsequent to the first paging slot; and in response to a determination that the location of the terminal as determined during the second paging slot is different from the location of the terminal as determined during the first paging slot, provide, to the memory for storage therein, information associated with the location of the terminal as determined during the second paging slot. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 20)

17. An apparatus for use in obtaining information about a location of a terminal, the apparatus comprising:
-
means determining a location of the terminal during a plurality of paging slots in which the terminal listens for pages from a wireless network, wherein the terminal is configured with the paging slots repeating periodically according to a paging cycle, and wherein determining the location of the terminal during the paging slots comprises determining the location of the terminal during a logging interval in which at least one location change is logged, the logging interval spanning multiple paging slots; means determining whether the location of the terminal as determined during a second paging slot is different from the location of the terminal as determined during a first paging slot, the second paging slot being subsequent to the first paging slot; and in response to a determination that the location of the terminal as determined during the second paging slot is different from the location of the terminal as determined during the first paging slot, means storing information associated with the location of the terminal as determined during the second paging slot.

18. A non-transitory computer-readable medium having code stored therein which is executable by a processor of a terminal to:
-
determine a location of the terminal during a plurality of paging slots in which the terminal listens for pages from a wireless network, wherein the terminal is configured with the paging slots repeating periodically according to a paging cycle, and wherein determining the location of the terminal during the paging slots comprises determining the location of the terminal during a logging interval in which at least one location change is logged, the logging interval spanning multiple paging slots; determine whether the location of the terminal as determined during a second paging slot is different from the location of the terminal as determined during a first paging slot, the second paging slot being subsequent to the first paging slot; and in response to a determination that the location of the terminal as determined during the second paging slot is different from the location of the terminal as determined during the first paging slot, store information associated with the location of the terminal as determined during the second paging slot.
