Method and apparatus for managing use of location determination

摘要

A method and apparatus to help detect that a particular location determination process is unreliable and to help exclude location fixes established with that location determination process from being used as a basis to provide a location-based service. In accordance with the disclosure, a server may receive at least three location fixes for a mobile station, all corresponding with each other in time and each established with a different location determination process, and the server may determine that one of the location fixes is relatively far away from the other location fixes and therefore that the location determination process used to establish that location fix is unreliable. In response to determining that the location determination process is unreliable, the server or another entity may then exclude location fixes established with that location determination process from being used as a basis to provide a location-based service.

主权项

1. A method comprising:
receiving into a network server a plurality of location fixes each defining a location of a mobile station, the plurality of location fixes defining multiple groups of three or more location fixes, wherein the three or more location fixes in each group are established for the same mobile station as each other, and wherein the three or more location fixes in each group correspond with each other in time but are established by different respective location determination processes than each other, wherein each group includes one location fix established by a particular location determination process; determining by the network server that, in each group of three or more location fixes, the one location fix in the group that was established by the particular location determination process is an outlier compared with the other location fixes in the group; and responsive to at least the determining, excluding, from use as a basis to provide a location-based service, location determined by the particular location determination process.
