Apparatus and method for identifying a moving wifi access point and managing connections therewith

Abstract

A server has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to collect scan lists from client devices. Each scan list specifies a WiFi access point identifier collected by a client device and geographic coordinates of the client device when the WiFi access point identifier was collected. A cluster of geographic coordinates is formed around a designated WiFi access point. A centroid within the cluster is identified. The location of the centroid is ascribed as the geographic position of the designated WiFi access point. A client device is advised when the designated WiFi access point is a known mobile WiFi access point to facilitate connection between the client device and the known mobile WiFi access point.

1 . A server, comprising:
 a processor; and   a memory connected to the processor, the memory storing instructions executed by the processor to:
 advise a client device when a first designated WiFi access point is a known mobile WiFi access point, 
 apply mobility criteria when a second designated WiFi access point is unknown or is believed to be a stationary WiFi access point, 
 categorize the second designated WiFi access point as a mobile WiFi access point or a stationary WiFi access point to form a categorized WiFi access point, and 
 add the categorized WiFi access point to a WiFi access point list, wherein the WiFi access point list categorized moving WiFi access points. 
   
     
     
         2 . The server of  claim 1  further comprising instructions executed by the processor to
 collect scan lists from client devices, wherein each scan list specifies a WiFi access point identifier collected by a client device and geographic coordinates of the client device when the WiFi access point identifier was collected, 
 form a cluster of geographic coordinates around a designated WiFi access point, 
 identify a centroid within the cluster, 
 ascribe the location of the centroid as the geographic position of the designated WiFi access point. 
 
     
     
         3 . The server of  claim 2  further comprising instructions executed by the processor to rank the scan lists. 
     
     
         4 . The server of  claim 3  wherein the instructions executed by the processor to rank the scan lists is based upon a mobile device value, a signal value and a measure of geographic accuracy. 
     
     
         5 . The server of  claim 4  wherein the mobile device value is a function of whether global positioning data is enabled on the mobile device. 
     
     
         6 . The server of  claim 4  wherein the signal value is a measure of signal strength from the designated WiFi access point. 
     
     
         7 . The server of  claim 4  wherein the measure of geographic accuracy is derived from geographic accuracy information from the mobile device and a measure of the age of the geographic information. 
     
     
         8 . A client device, comprising:
 a processor; and   a memory connected to the processor, the memory :storing instructions executed by the processor to:
 enable WiFi access point requests in response to a confirmed stationary state of a mobile device, 
 enable WiFi access point requests in response to a confirmed in-motion state of the mobile device and an available moving WiFi access point, and 
 disable WiFi access point requests in response to the confirmed in-motion state of the mobile device and no available moving WiFi access point. 
   
     
     
         9 . The client device of  claim 8  wherein the stationary state includes motion characteristic of an individual walking with the client device. 
     
     
         10 . The client device of  claim 9  further comprising instructions executed by the processor to send a scan list to a server, wherein the scan list specifies a WiFi access point identifier collected by the client device and geographic coordinates of the client device when the WiFi access point identifier was collected.
