The network management entity 150 receives the attach request 210 and the network management entity 150 may be arranged to detect mentioned pieces of information from the received attach request 210. In response to the detection the network management entity 150 may be arranged to allocate a network node 160 to the attach request 210. The network node 160 may at least be arranged to control the communication channel implementing Non-IP Data Delivery functionality. The controlling may e.g. refer to establishing and managing a communication channel with a service the network node 160 is configured to implement to. As mentioned, the network management entity 150 may be arranged to allocate the network node 160 for a communication in accordance with the information carried in the attach request 210. The allocation may comprise, among other items, a generation of a signal 220 to the network node 160. The network node 160 to which the signal 220 is generated may be determined by the network management entity 150 in accordance with the information received in the attach request 210. For example, in response to a detection that the attach request 210 carries the indication on the emergency situation the network management entity 150 may inquire, e.g. from a memory accessible to it, a network node 160 arranged to serve in a communication relating to the emergency situation. In response to the determination of the network node 160 for the task the signal 220 is generated wherein the signal may carry an information that the communication device 110 requests communication service and it is to be attached to the network node 160. The signal 220 may carry information, such as an identifier of the communication device 110 or the session initiated by the communication device 110, to the network node 160. The network node 160 may be arranged to indicate an acceptance of the attach to the network management node 150 with the signal 230. Further, the network management entity 150 may be arranged to generate an acknowledgement signal 240 to the communication device 110 for indicating that the attachment as requested is accepted. In response to a detection by the communication device that the attach request is accepted the communication device 110 may be arranged to generate 250 an emergency notification. The generation of the emergency notification 250 may comprise, but is not limited to, a formatting a message complying a message format conveyable over the communication channel implementing Non-IP Data Delivery functionality. Additionally, the message representing the emergency notification may be formatted so that predetermined piece or pieces of information is included in the message, such as in the payload of the message. According to an embodiment of the invention the piece of information to be included in the message may at least comprise data by means of which a location of the communication device 110 may be determined. The data representing the location may e.g. be GPS coordinates or any other data by means of which the location of the communication device 110 may be determined. Naturally, the communication device 110 is such that it is suitable for providing the data from which the location may be derived. Alternatively or in addition, the communication device 110 may be configured to include further data obtainable from a memory device accessible to the communication device 110 in the message representing the emergency notification. Such information may e.g. be personal data representing a user of the communication device 110. An advantage of such an arrangement is that the person who initiated the generation of the emergency notification may provide information on himself/herself to an emergency call center without verbal communication and the person taking care of the emergency call may obtain information about the person from suitable databases, such as databases storing health information. This may be utilized in a preparation of the intervention to the emergency situation. In response to the generation of the emergency notification it may be transmitted to the network management entity 150 with a signal 260. The signal 260 may advantageously be transmitted over non-access stratum (NAS) layer, by utilizing the Non-IP Data functionality, from the communication device 110 to the network management entity 150. In response to the receipt of the emergency notification the network management entity 150 may be arranged to generate a signal 270 representing the emergency notification, e.g. by forwarding it as such or by modifying it according to a need, to the network node 160. The network node 160 supporting the messaging as described may detect that the signal 270 carries the emergency notification and it may be arranged to convey the signal, as such or by modifying it according to a need, to an emergency call center 170. This is indicated with a signal 280 in FIG. 2.
