Correspondingly, FIG. 4 illustrates schematically at least some aspects of an operation according to an embodiment of the invention from a network management entity 150 point of view. There, the network management entity 150 may receive 410 the attach request 210 from the communication device 110. The network management entity may be arranged to process the data and detect information 420 carried in the attach request 210. In response to a detection that the attach request 210 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 the network management entity 150 may be arranged to allocate 430 a network node 160, which controls the communication channel implementing Non-IP Data Delivery functionality, to the attach request. On the other hand, if an outcome of the detection 420 is that the attach request does not carry the information causing the detection the network management entity 150 may be arranged to handle 440 the received attach request in a normal manner i.e. not as a signaling related to an emergency situation. For example, the signaling may not be assigned with a high priority. Now, if the network node 160 is allocated to the attach request 210 for implementing at least a part of the communication over Non-IP Data Delivery functionality, the network management entity 150 may be arranged to generate 450 a response 240 to the communication device 110 for indicating an acceptance of an attachment. Next, the network management node 150 may receive 460 an emergency notification 260 from the communication device 110 over the communication channel implementing Non-IP Data Delivery functionality. In response to the receipt of it, the network management entity 150 may be arranged to generate 470 a signal 270 for indicating the emergency situation to the network node 160, which indication is to be delivered to an emergency service center 170 by the network node 160. In case the emergency notification 260 carries further information the network management node 150 may be arranged to include it to a signal 270 as such or by modifying it in some manner.
