Question: What happens when a mobile station's (MS) mobility management signaling request is rejected by the network due to a dedicated core network?
Option 1: The MS will automatically switch to a different core network.
Option 2: The mechanism for general NAS level mobility management congestion control is followed.
Option 3: The MS will be disconnected from the network.
Option 4: The request will be re-routed through a different signaling path.
Explanation: When the network rejects an MS's mobility management signaling request due to a dedicated core network, it triggers the general NAS level mobility management congestion control mechanism. This ensures that the network can manage congestion and prioritize signaling requests effectively.
