According to a fifth aspect, a network management entity for generating a signal indicating an emergency situation is provided, the network management entity comprises: at least one processor; at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the network management entity to perform: receive an attach request from a communication device; in response to a detection that the attach request carries information indicating that an attachment is requested to a communication channel implementing Non-IP Data Delivery functionality and information representing that the attachment is requested for delivering an emergency notification allocate a network node controlling the communication channel implementing Non-IP Data Delivery functionality to the attach request; in response to an allocation of the network node generate a response to the communication device indicating an acceptance of an attachment; receive an emergency notification over the communication channel implementing Non-IP Data Delivery functionality; and generate a signal indicating the emergency situation to the network node allocated to the attach request to be delivered to an emergency service center.

The network management entity may further be caused to perform: detect, in response to a receipt of the emergency notification, that the emergency notification carries further data to be transmitted to the emergency service center. The network management entity may further be caused to perform: add the further data in a signal for transmitting it from the network management entity to the network node.
