Question: In a Location Services (LCS) scenario, what characterizes the state of a Gateway Mobile Location Centre (GMLC) when it has just received a location request from an LCS client but hasn't yet authenticated the request's details?
Option 1: IDLE State - indicating readiness to process new requests.
Option 2: NULL State - where the GMLC verifies the client's identity and request nature.
Option 3: ACTIVE State - signifying ongoing location calculation or retrieval.
Option 4: PENDING State - implying a temporary hold due to insufficient resources.
Explanation: The NULL State is characterized by the GMLC not having initiated processing of a location request. Immediately upon receiving a new request, before authentication and processing, the GMLC conceptually remains in this state, focusing on verifying the client's identity and the nature of the request.
