The invention as described above is based, at least in part, to a communication between a network management entity 150 and a network node 160. A non-limiting example of the network management entity 150 is a Mobility Management Entity implementing control functions among other tasks in LTE networks. The network node 160 suitable for implementing the Non-IP Data Delivery functionality may e.g. be so-called SCEF (Service Capability Exposure Function) which may provide machine type communication inter-working functions for the purpose of the present invention. Alternatively, the network node 160 may consists of a plurality of network elements, such as SGW (Serving Gateway) element and PGW (Packet Data Network Gateway), by means of which the Non-IP Data Delivery functionality may be implemented to.

Furthermore, the communication with respect to the emergency situation may require a communication channel that is secure to use e.g. because the data carried in the emergency notification may be private but also because it is important that 3^rd parties may not access the data carried in the emergency notification. An applicable communication channel to be used for the purpose of the present invention may be so-called BEST (Battery Efficient Security for Very Low Throughput MTC Devices). The BEST channel is a secure communication channel applicable for communication between a communication device 110 and a service entity in question, such as an emergency service center 170. An establishment of the BEST channel may comprise operations relating to session initiation and agreement on keys to be used for securing the communication channel, session key management, and so on.
