We all know that the future involves connecting things as well as people. By 2025, 50 billion connected things will be communicating over mobile networks, ten times the number of people connected today.
Much talk and effort has gone into how these IoT devices will be connected and the acronym makers have been in full swing – EC-GSM (Extended Coverage GSM), NB-IoT (Narrow Band IoT) and eMTC (enhanced Machine Type Communication) being just a few.
So connectivity is covered – but what about the data these ‘things’ will produce? With the wide range of applications envisaged for IoT, how can we deal with their hugely differing data requirements?
For example, consider a temperature sensor reporting the temperature of a room to a building management system. If the amount, timeliness or quality of the data isn’t so great, there is no real problem – optimizing the comfort of occupants is good to achieve but not a matter of life and death.
In contrast, consider an autonomous car – with sensors requiring a constant stream of high quality data that never drops – and even the potential for remote surgery.
With sensors and applications having differing requirements for access, mobility, throughput, device power, service quality and priority, the key to managing all that data is Subscriber Data Management (SDM). SDM needs to bring service efficiency at the lowest cost, as well as extreme scalability and the ability to support data analytics. It must also be robust to ensure that when needed, the data will always get through. It needs to support specific profiles for particular types of device to optimize usage of network resources, allow profile sharing between similar IoT devices for further capacity gains, and offer overload protection. It also needs to be open for easier integration of new IoT services and faster time to market. Virtualizing front end applications can help deliver on most of these aspects.

All requirements are met by Nokia’s SDM solution. Its SDM IoT architecture complies with 3GPP standards to be interoperable with today’s IoT devices, while offering an easy route to tomorrow’s full cloud-based SDM solution. Robustness is ensured with mechanisms that indicate the overload, stabilize the network during the overloads and take action to eliminate it – measures include rejecting further calls, prioritizing demand by dropping non-essential data packets, and offloading to geo-redundant SDM platforms when necessary.
And whether your network is 2G, 3G, LTE or 5G, Nokia SDM offers extensive vertical support. It’s also highly scalable, supporting more than 250 million subscribers – simply add more back ends for subscriber capacity or more front ends for transaction capacity. Dedicated front ends allow separation between machine traffic and human generated traffic. Furthermore, backend data can be organized in logical groups depending on the type of IoT service. This modularity is very much in line with the 5G network slicing concept of allocating virtual network resources to different use cases and operating them independently.
There is no time to waste in preparing for the diverse data demands of the vast new world of IoT headed our way. Nokia SDM is ready to help you get started now.
