Abstract
Techniques disclosed herein help a location server identify inaccuracies in a list of neighboring cells provided by the location server by enabling mobile devices to, during an OTDOA session to opportunistically take Reference Signal Time Difference (RSTD) measurements of additional cells not on the neighboring cell list. The mobile device can then provide these RSTD measurements back to the server, which can optimize its algorithm for determining neighboring cells based on these measurements.
