A cellular radio communications system is subject to a number of threats, which are outlined in the diagram below..The motivations for attacks against cellular networks typically fall into one of the following categories: attempts at unauthorised network access to get free services attempts at ‘grabbing’ user identities to make clones attempts at eavesdropping on network traffic to gain unauthorised access to information attempts at tracking users by eavesdropping on signalling traffic The vulnerability of cellular systems to these threats is based mainly on the fact that they employ radio-based user connections.Typically, the most vulnerable parts of the cellular system are...

Voice over LTE VoLTE stands for Voice over LTE and it is the umbrella term covering all methods of transporting voice and other Circuit Switched (CS) services over an LTE / 4G network. It is also the specific term applied to the provision of those services via an IP Multimedia Subsystem (IMS) rather than a legacy CS core network. The supporters of VoLTE claim, with some justification, that it’s the voice solution LTE was designed to support. Other methods of providing voice and CS services, such as CS Fallback, are simply transitional steps that operators can take on the way...

Railway networks depend on telecoms.  Without adequate systems in place, trains would not be able to run. GSM-R, adopted in most European countries following International Union of Railways (UIC) guidelines, provides a vital radio communication link between train drivers and signallers, as well as supporting the European Train Control System (ETCS), which details train movements without the need for lineside signalling. Internet Protocol (IP) technologies are used widely in support of signalling activities, critical communication links, surveillance and CCTV monitoring amongst many others, supported by an extensive fibre and copper network. Wi-Fi provides connectivity to the internet for passengers but...

Mission critical communications are currently supported by the Airwave network; however by the end of 2019 it is the intention of the government to replace this network with a more cost-effective and up-to-date broadband communications system. The main issue is that time is running out. The government has chosen a system - LTE (Long Term Evolution); however LTE was never designed for mission critical communications. It was designed to provide mobile communications to smart devices, offering quicker access to data. What this means is that the LTE systems needs to be adapted to make it suitable for mission critical communications,...
