Question: What is the primary reason for a User Equipment (UE) to return an error code of '3' when initiating a new positioning session, as per 3GPP standards?
Option 1: Insufficient satellite signals are available for triangulation.
Option 2: The network is experiencing high traffic, leading to connection failures.
Option 3: The UE is already engaged in an ongoing positioning session and does not support multiple simultaneous sessions.
Option 4: There is a memory allocation error within the UE's system.
Explanation: This answer highlights a nuanced aspect of UE capability and session management, where error codes convey specific states or limitations of the UE, impacting how users and networks manage concurrent activities.
