Abstract:
1. A method of operating a position determining entity filter, the method comprising: receiving a request for location assistance data transmitted from a wireless communication device, wherein the request is associated with a source packet address and includes a user identifier for a user of the wireless communication device; processing the request to determine if the user identifier is associated with the source packet address; if the user identifier is not associated with the source packet address, initiating a count to track a number of requests for the location assistance data transmitted from the wireless communication device, and removing data previously associated with the user identifier and the source packet address; if the user identifier is associated with the source packet address, incrementing the count and determining if a flag is assigned to the user identifier; if the flag is assigned to the user identifier, inhibiting future requests; and if the flag is not assigned to the user identifier, determining if the count exceeds a threshold, and if the count exceeds the threshold, assigning the flag to the user identifier.
