“…Similar to the previous testing sequence, there was a total of 10 consecutive runs each with 1000 and 2000 SIP NOTIFY messages that were transmitted to the PSAP with various rates. It is evident that there is no correlation to the behaviour of SIP NOTIFY messages with the overall number of transmitted messages, while in the same time there is an almost linear increase of the unacknowledged SIP NOTIFY messages number against the overall number of exchanged messages [3].…”

“…Such testing will reveal possible limitations of the emergency communication platform SIP core (ECRF, ESRP) on handling inbound SIP traffic, mostly containing SUBSCRIBE/NOTIFY messages, under load. In all testing cases, SIPp (http://sipp.sourceforge.net/ accessed on 12 February 2022) , a free Open Source traffic generator for the SIP protocol was used for stressing the SIP protocol's behavior while NetEm (https://wiki.linuxfoundation.org/networking/netem accessed on 12 February 2022) was used for emulating diverse networking behavior [3].…”

“…The imminent deployment of 5G networking infrastructure is expected to offer massive connectivity, coverage and availability, extremely high data rate, less than 1 ms end-to-end over-the-air latency, significantly larger capacity and throughput, real-time information processing and data transmission along with native support for diverse verticals, services and applications, each with different specification and requirements [2]. In regards to response-capable healthcare solutions, improved device-to-device communication will expand the uplink capacity and availability of communication channels, creating an always connected experience for patients, healthcare personnel and emergency workers, which will now have improved awareness through access to high-quality multimedia content [3]. The novel feature of network-slicing introduced by 5G, is expected to facilitate dynamic adaptation of both transmission speed and network latency, thus ensuring high priority for emergency communications as a whole.…”

The fifth generation (5G) of mobile networks is designed to mark the beginning of the hyper-connected society through a broad set of novel features and disruptive characteristics, delivering massive connectivity, coverage and availability paired with unprecedented speed, throughput and capacity. Such a highly capable networking paradigm, facilitated by its integrated segments and available subsystems, will propel numerous cutting-edge, innovative and versatile services, spanning every possible business vertical. Augmented, response-capable healthcare services have already been identified as one of the prime objectives of both vendors and customers; therefore, addressing controversies and shortcomings related to the specific field is considered a priority for all stakeholders. The scope of this paper is to present the architectural elements of 5G which enable efficient, remote healthcare services along with emergency health monitoring and response capability. In addition, we propose a holistic scheme based on technical enablers such as Internet-of-Things (IoT) and Fog Computing, for mitigating common issues and current limitations which may compromise the proclaimed service delivery.

“…Normally in a narrow sense of external structure, network typology has a dendrite structure, linear/circular structure (Martin & Dwyer, 2019), lattice structure, and small-world structure (Ch'ng, 2015). In the practical sense, the regular network typology tends to oversimplify the structure, while taking perspectives of transmission conduits (Chen et al, 2019) and multi-layer of information processing (Politis et al, 2018).…”

Digital media platforms are used to make social contacts, especially during the COVID-19 pandemic. Journalism also adopts mobile and social platforms into news production and distribution. The usage of digital media platforms in journalistic practices has shown some interlinkage with political participation. Against these backdrops, there is a need for a theoretical framework to analyze the interlinkage and the relevant influence on social activities. This article uses a conceptual approach and theorizes platformization to explicate the rationale behind the interaction between digital platforms, mobile journalism, and political participation. Platformization in this study inspects media as mediated and dynamic platform that values interactivity and data. We also argue that the thesis of platformization derives from mediatization theory, and consists of platform logic and platform architecture. Platform logic is represented by platform functionality, platform automation, mobile mediality, and platform-based sociality. Platformization is structured by the platform architecture in the communication activities. Platform architecture has two senses. Firstly, it has the sense of internal structure, i.e., the engineering structure of software and hardware. Secondly, it contains the sense of external structure, i.e., the platform’s structural position in the platform ecosystem.

“…In the verge of the 5G deployment, telecommunication providers are switching rapidly towards an All-IP infrastructure leaving behind the Public Switched Telephone Networks (PSTN). Therefore, next generation emergency services are bound to be provided over IP networks as well, with larger data sets for delivering real-time sensing data, accurate geodesic location and rich multimedia content to first responders[71],[72].…”

On Identifying Threats and Quantifying Cybersecurity Risks of Mnos Deploying Heterogeneous Rats

Wireless networks constitute a significant attack vector for adversaries due to their wide usage in our everyday life. As the fifth generation of wireless networks reaches maturity, several vulnerabilities affecting earlier generations have been resolved. Nevertheless the coexistence of legacy wireless technologies is giving rise to the risk of allowing adversaries to perform downgrade attacks, thus bypassing the improved security of the state-of-the-art communication networks. Vulnerabilities due to the trade-off between security and usability could also exist in the latest wireless networking technologies; hence mobile network operators need to be aware of the risks related to both protocol vulnerabilities and configuration defects. The paper proposes a methodology for the systematic identification of vulnerabilities associated with wireless access protocols and systems and the quantitative evaluation of the resulting risks for mobile operators using attack trees and based on the current legislative frameworks. The proposed methodology has been designed to aid both, mobile operators towards planning more effective cybersecurity strategies and adopt efficient defences to minimise the probability of an attack and predict its impact on the operational, market and business aspects of mobile network operators. The proposed risk assessment analysis is evaluated over three distinct vertical scenarios, namely an emergency call, a high-speed train commute and a massive public event, with the most relevant threats and their impact being measured and discussed. The evaluation of the model revealed significant results for mobile network operators that are deploying a mix of legacy and state of the art cellular technologies.
