Question: In an LCS (Location Services) scenario, if the requested location information cannot be satisfied by cell identity alone and the E-SMLC determines a positioning method, what action may the E-SMLC take if the initial position method fails to obtain measurements but sufficient response time remains?
Option 1: The E-SMLC will immediately send a Location Response with an approximate location estimate based on the current cell identity.
Option 2: The E-SMLC may instigate a further location attempt using the same or a different position method to try and meet the requested accuracy.
Option 3: The E-SMLC will notify the MME (Mobility Management Entity) of the failure and await further instructions before proceeding.
Option 4: The E-SMLC will only return a vertical location coordinate if available, even if horizontal coordinates were successfully obtained.
Explanation: According to LCS procedures, if the initial positioning method fails but there is still sufficient response time left, the E-SMLC can attempt another location estimation using either the same or a different positioning method to meet the requested accuracy within the specified Quality of Service (QoS) timeframe.
