Method and system for associating a cell-sector with time-dependent location parameters
First Claim
1. A method, comprising:
- receiving from a requestor a request to locate a mobile station;
in response to said request, determining that a serving area provided by a base transceiver station of a wireless network is serving said mobile station at a current date and a current time of day;
in response to determining that said serving area is serving said mobile station at said current date and said current time of day, accessing data storage that stores geographic parameters associated with said serving area, wherein said stored geographic parameters associated with said serving area include respective geographic parameters for each of a plurality of time periods;
selecting a representative location associated with said serving area based on said stored geographic parameters associated with said serving area and at least one of said current date and said current time of day;
selecting at least one uncertainty parameter associated with said representative location based on said stored geographic parameters associated with said serving area and at least one of said current date and said current time of day; and
reporting said representative location and said at least one uncertainty parameter to said requestor.

Abstract
A set of location fixes is obtained for a plurality of mobile stations, wherein each mobile station is served by a serving area of a wireless network at a respective date and time of day. The set of location fixes is used to determine different geographic parameters that apply to the serving area for different time periods (e.g., different days of the week and/or times of day). A location server may receive a request to locate a mobile station that is being served by the serving area at a current date/time. The location server may select a representative location and at least one uncertainty parameter based on the geographic parameters that apply to the serving area for the time period corresponding to the current date/time, and report the representative location and at least one uncertainty parameter in response to the request.

14. A method, comprising:
-
obtaining, for a serving area provided by a base transceiver station of a wireless network, during a collection period, a set of location fixes for a plurality of mobile stations, wherein each of said location fixes is obtained for a respective mobile station being served by said serving area at a respective date and time of day within said collection period, wherein said mobile stations are configured to wirelessly communicate with said wireless network; defining a plurality of time periods; dividing said set of location fixes into a plurality of time-period-subsets, such that each time period in said plurality of time periods is associated with a respective time-period-subset of said set of location fixes; and for each given time period in said plurality of time periods, (i) determining a set of geographic parameters that cooperatively define a geographic area encompassing at least some location fixes in said given time period'"'"'s respective time-period-subset, and (ii) storing, in data storage, a record that associates said set of geographic parameters with said serving area and said given time period. - View Dependent Claims (15, 16, 17, 18)

19. A system, comprising:
-
a processor; data storage; and program instructions stored in said data storage, wherein said program instructions are executable by said processor to cause said system to perform functions, said functions comprising; receiving a request to locate a mobile station; in response to said request, determining that a serving area provided by a base transceiver station of a wireless network is serving said mobile station at a current date and a current time of day; in response to determining that said serving area is serving said mobile station at said current date and said current time of day, accessing data storage that stores geographic parameters associated with said serving area, wherein said stored geographic parameters associated with said serving area include respective geographic parameters for each of a plurality of time periods; selecting, from said stored geographic parameters, geographic parameters for a time period in said plurality of time periods corresponding to at least one of said current date and said current time of day; selecting a representative location and at least one uncertainty parameter based on said selected geographic parameters; and reporting said representative location and said at least one uncertainty parameter. - View Dependent Claims (20, 21)
