The method comprises the UE 110 receiving a first message 150 containing an indicator 160 indicating that an emergency-related request has been made, the UE 110 recognizing the indicator 160 as an indication that the emergency-related request is related to an emergency, and the UE 110 sending a second message 170 containing emergency-related information 180 about itself.
