Systems for and methods of determining likelihood of relocation of reference points in a positioning system
First Claim
1. A method of determining a measure of likelihood that an estimated geographic location associated with a designated wireless device is not an accurate present location of the wireless device, the method comprising:
- determining a set of one or more reference points associated with the designated wireless device, the one or more of the reference points being at least one of (i) a geographic position at which signals from the designated wireless device were detected and (ii) another wireless device having a relationship with the designated wireless device, an existence of the relationship being based on the designated wireless device and the another wireless device being within signal reception range of a same position within a selected period of time;
retrieving at least one of (i) attributes of the reference points of the set and (ii) attributes of the relationships between the designated wireless device and the one or more other wireless devices of the set; and
determining a measure of likelihood that the estimated geographic location associated with the designated wireless device is not the accurate present location of the designated wireless device based on at least one of (i) the attributes of the reference points of the set and (ii) the attributes of the relationships between the designated wireless device and the other wireless devices of the set.

Abstract
Systems and methods are provided for determining a measure of likelihood that an estimated geographic location of a designated wireless device is not its accurate present location includes determining a set of reference points associated with the device, which are a geographic position at which signals from the device were detected and/or other devices having a relationship with the designated device. The existence of the relationship is based on the devices being within signal reception range of a same position within a selected period of time. The method includes retrieving attributes of the reference points and/or of the relationships and determining a measure of likelihood that an estimated geographic location associated with the designated device is not its present location based on the attributes of the reference points of the set and/or of the relationships.

19. A method of determining a measure of likelihood that an estimated geographic location associated with a designated wireless device is not an accurate present location of the wireless device, the method comprising:
-
determining a first set of one or more wireless devices that have a relationship with a designated wireless device, an existence of the relationship being based on the designated wireless device and the wireless devices of the set being within signal reception range of a same position within a selected period of time; determining pairwise connections between the wireless devices of the set based on at least one of (i) estimated distances between the wireless devices of a corresponding pair and (ii) relationships between the wireless devices of the corresponding pair, the existence of the relationship being based on the corresponding pair of wireless devices being within signal reception range of a same position within a selected period of time; partitioning the wireless devices into groups based on a count of a number of pairwise connections crossing any partition; determining a count of the number of wireless devices in each group; and determining a measure of likelihood that the estimated geographic location associated with the designated wireless device is not an accurate present location of the wireless device based on the counts of the number of wireless device in each group and based on the group of which the designated wireless device is a member. - View Dependent Claims (20, 21)

22. A system for determining a measure of likelihood that an estimated geographic location associated with a designated wireless device is not an accurate present location of the wireless device, the system comprising:
-
a non-transitory computer readable media including instructions that when executed by a computer system cause the computer system to; determine a set of one or more reference points associated with a designated wireless device, the one or more of the reference points being at least one of (i) a geographic position at which signals from the designated wireless device were detected and (ii) another wireless device having a relationship with the designated wireless device, an existence of the relationship being based on the designated wireless device and the another wireless device being within signal reception range of a same position within a selected period of time; retrieve at least one of (i) attributes of the reference points of the set and (ii) attributes of the relationships between the designated wireless device and the one or more other wireless devices of the set; and determine the measure of likelihood that the estimated geographic location associated with the designated wireless device is not an accurate present location of the wireless device based on at least one of (i) the attributes of the reference points of the set and (ii) the attributes of the relationships between the designated wireless device and the other wireless devices of the set. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A system for determining a measure of likelihood that an estimated geographic location associated with a designated wireless device is not an accurate present location of the wireless device, the system comprising:
-
a non-transitory computer readable media including instructions that when executed by a computer system cause the computer system to; determine a first set of one or more wireless devices that have a relationship with a designated wireless device, an existence of the relationship being based on the designated wireless device and the wireless devices of the set being within signal reception range of a same position within a selected period of time; determine pairwise connections between the wireless devices of the set based on at least one of (i) estimated distances between the wireless devices of a corresponding pair and (ii) relationships between the wireless devices of the corresponding pair, an existence of the relationship being based on the corresponding pair of wireless devices being within the signal reception range of the same position within the selected period of time; partition the wireless devices into groups based on a count of a number of pairwise connections crossing any partition; determine a count of the number of wireless devices in each group; and determine the measure of likelihood that the estimated geographic location associated with the designated wireless device is not the accurate present location of the wireless device based on the counts of the number of wireless device in each group and based on the group of which the designated wireless device is a member. - View Dependent Claims (41, 42)
