Ensuring Protection of Subscriber Data in Mobile Networks

Critical devices such as smartphones, tablets, and other mobile devices have become an integral component of both professional and personal lives. As a result, both the number of mobile network subscribers and the number of devices per user has steadily increased over the previous two decades. This trend will continue, driven not only by the growing number of individuals using mobile devices, but also by the industry where effective network monitoring is a requirement and therefore, an increasing number of devices will be monitored or actively communicated with over mobile networks.

Collection of machine health data, over transmission of power generation or power consumption data in smart grids, connection between Information Technology (IT) and Operational Technology (OT) in enterprises, to Vehicle-to-Vehicle (V2V) and Vehicle-to-Everything (V2X) communication are all examples of industrial use cases. These use cases typically build on new features introduced with 5G mobile networks, and rely heavily on the trustworthiness of such mobile networks and their ability to protect confidentiality, integrity and authenticity of subscriber identities and transmitted information.
