Abstract: Systems and techniques to determine an approximate location for a mobile device using historic location information. In an aspect, a SUPL Location Platform (SLP), which is a location server in SUPL, may receive data from SUPL Enabled Terminal (SET). The data may include the Multiple Location IDs Parameter. The real time Location ID Parameter may not have a current status. The SLP may determine an approximate position for the SET based on the Multiple Location IDs Parameter data received from the SET. The SLP may then send the approximate position to the SET or a SUPL Agent, or may use the approximate position information in another way.
