Due to the difficulties of the implementation of NGN networks, relevant complexity of used NGN's equipment, unlimited set of services and unguaranteed QoS level for different services, ITU-T SG11 has been discussing the concept of a model network since 2006.
The first Recommendation ITU-T Q.3900 (2006) "Methods of testing and model network architecture for NGN technical means testing as applied to public telecommunication networks" became the basic standard for NGN testing. Afterwards, there was a discussion on the global interoperability concept as a next step of testing methodology for NGN networks. The global interoperability includes the technical means interoperability, the interoperability of services and interoperability of networks for providing the guaranteed level of QoS. The set of Recommendations, which are based on the model network and global interoperability concepts, was developed during study periods 2005-2008, 2009-2012 in collaboration with experts from Russia, Austria, China, Japan, Korea, Poland.
In principle, the same concept can be used for IoT testing, but the ITU-T Q.3900 does not have the framework for a particular technology such as IoT. Therefore, the creation of a particular concept for IoT can be done as a separate work item. This work item can be started under Q12/11 which was established at the WTSA-12.
The concept of the model network of Q.39_IoT_MN_test includes Flying Ubiquitous Sensor Networks and is based on the best practice of the SPbSUT's "IoT Laboratory" which was established in 2012 and presented at the ITU Kaledoscope-14.
