Question: In a Best Effort Class for Location Services (LCS) as per 3GPP standards, what happens if a location estimate is obtained but does not meet the requested Quality of Service (QoS) requirements?
Option 1: The location estimate is discarded and an error cause is sent to the requester.
Option 2: The location estimate is returned with an indication that the requested QoS was not met.
Option 3: The system automatically initiates a retry to achieve the requested QoS before responding.
Option 4: The request is escalated to a higher priority class to ensure QoS requirements are met.
Explanation: In the Best Effort Class, the focus is on providing a location estimate even if it doesn't fully meet the requested QoS. Thus, if an estimate is obtained but fails to meet all QoS criteria, it is still returned to the requester, accompanied by a notification indicating the shortfall in QoS achievement.
