Question: What is the primary purpose of the EMM INFORMATION message sent by the network in an Evolved Packet System (EPS)?
Option 1: To establish a new EMM context with the User Equipment (UE).
Option 2: To send specific information to the UE when an EMM context is already established.
Option 3: To request the UE to perform a specific action or measurement.
Option 4: To notify the UE of changes in network configuration.
Explanation: The EMM INFORMATION message is used by the network to convey certain information to the UE when an EMM context has already been established. This message type allows for communication from the network to the UE without requiring a specific action or response from the UE, other than acknowledging receipt of the information if necessary.
