Detecting false base stations in mobile networks

3GPP standardization takes yet another step to combat false base stations. The security group in 3GPP (called SA3) identified that radio condition information received from devices – which is an integral part of all generations of mobile networks (2G/3G/4G/5G) – could contain fingerprints of false base stations. SA3 has described a solid framework based on this information, enabling mobile networks to reliably detect such false base stations. The framework complements other mechanisms introduced in 5G to protect users against false base stations, for example encrypted long-term identifiers and fresh short-term identifiers. This blog post outlines the framework and describes some practical experiments we have performed in our lab.

Machine Intelligence at the NOC

Network Operations Centers – the centralized monitoring and control stations for telecom networks – primarily deal with fault management and performance management to maintain network efficiency and customer satisfaction. The already high degree of automation in Ericsson’s NOCs is being enhanced using machine intelligence technologies – advanced analytics, deep learning, machine reasoning – to drive intelligent network operations that will enable emerging 5G systems to be highly performant while also being easy to use

QUIC – a vehicle for transport protocol evolution

The Internet is evolving from both a usage and connectivity point of view as are the underlying architecture and protocols. The quest for more responsive applications, the emergence of new security and privacy concerns and the web style of design and implementation is impacting everything from ways of working to the delivery and deployment protocols and standards. The QUIC transport protocol is a concrete example of such impact. While the IETF is working on QUIC to create a usable and deployable transport protocol ensuring the protocol evolution, 3GPP is considering using QUIC for the 5G packet core. Hence, QUIC is becoming a vehicle for transport protocol evolution and we are actively contributing to that evolution.

Scaling cloud platforms the P2P way

With the size of centralized cloud deployments continuing to increase and with distributed and edge cloud deployments becoming a reality, how can cloud management platforms scale regardless of infrastructure size and shape? Can performance levels be maintained as scale increases? Centralized and hierarchical approaches have historically dominated but distributed approaches based on peer-to-peer (P2P) technologies are highly relevant to bring into the conversation.

How Ericsson and Telefónica built a cutting edge 5G-ready transport solution

Ericsson and Telefónica have together successfully showcased a traffic-agnostic 5G-ready transport solution for both Radio and Fixed Enterprise Access. It is based on Ericsson’s groundbreaking and future-proof eXhaul concept, which allows a wide range of transport technologies, including CPRI, eCPRI and Ethernet, to efficiently and securely share the same physical infrastructure.

Exploring how to build standards for Virtual Reality

Virtual reality (VR) has quickly become a household term. There are lots of gadgets and apps that let you take control of your viewing experience by letting you watch a film clip in any direction in a head-mounted display or simply by moving your phone or tablet. However, since most of these apps define their own vertical, content has to be adapted for each of them. This also means that many players are motivated to find common ground and define relevant standards for VR content delivery and consumption.

Wake-Up Radio – A key component of IoT?

Academic researchers have worked on wake-up receivers for some 10 years, with the goal of taking a disruptive step towards very low power consumption for wireless devices. In May 2016 the IEEE 802.11 Working Group took the first step towards standardizing wake-up receivers. This led to the formation of the 802.11ba Task Group, which is one of the groups within the IEEE 802.11 Working Group that attracts the most interest. The target is to have a draft 1.0 of the specification ready in May 2018.
