Responsible for studies relating to signalling requirements and protocols, including those for IP-based network technologies, NGN, M2M, IoT, FNs, Cloud Computing, mobility, some multimedia related signalling aspects, ad hoc networks (sensor networks, RFID, etc.), QoS, and internetwork signalling for legacy networks ATM, N ISDN and PSTN networks. In addition, studies relating to reference signalling architectures and test specifications for NGN and emerging network technologies (e.g., IoT etc.).
