NIDD – Non IP Data Delivery

For low power IoT devices which need to communicate with the network on a frequent or infrequent basis, utilizing an IP protocol stack for data delivery can be a power hungry process. NIDD allows the mobile and MME to utilize NAS signalling as a means of exchanging data messages related to IoT. This process is termed “EPS services with control plane CIoT (Cellular IoT) optimization”. The MME will act as the LTE network interface between the mobile and the SCEF (Service Capabilities Exposure Function).
