Artificial Intelligence - Beyond SON for Autonomous Networks


What is the next step in evolution of SON? Artificial Intelligence obviously. The use of artificial intelligence (AI) techniques in the network supervisory system could help solve some of the problems of future network deployment and operation. ETSI has therefore set up a new 'Industry Specification Group' on 'Experiential Networked Intelligence' (ISG ENI) to develop standards for a Network Supervisory assistant system.


The ISG ENI focuses on improving the operator experience, adding closed-loop artificial intelligence mechanisms based on context-aware, metadata-driven policies to more quickly recognize and incorporate new and changed knowledge, and hence, make actionable decisions. ENI will specify a set of use cases, and the generic technology independent architecture, for a network supervisory assistant system based on the ‘observe-orient-decide-act’ control loop model. This model can assist decision-making systems, such as network control and management systems, to adjust services and resources offered based on changes in user needs, environmental conditions and business goals.


The introduction of technologies such as Software-Defined Networking (SDN), Network Functions Virtualisation (NFV) and network slicing means that networks are becoming more flexible and powerful. These technologies transfer much of the complexity in a network from hardware to software, from the network itself to its management and operation. ENI will make the deployment of SDN and NFV more intelligent and efficient and will assist the management and orchestration of the network.


We expect to complete the first phase of ENI work in 2019. It will include a description of use cases and requirements and terminology, including a definition of features, capabilities and policies, which we will publish in a series of informative best practice documents (Group Reports (GRs)).
This will of course require co-operation from many different industry bodies including GSMA, ITU-T, MEF, IETF, etc.

Will see how this goes.

5G Security Updates - July 2017


Its been nearly 2 years since I last blogged about ETSI Security workshop. A lot has changed since then, especially as 5G is already in the process of being standardised. This is in addition to NFV / SDN that also applied to 4G networks.

ETSI Security Week (12 - 16 June) covered lot more than 5G, NFV, SDN, etc. Security specialists can follow the link to get all the details (if they were not already aware of).

I want to quickly provide 3 links so people can find all the useful information:

NFV Security Tutorialdesigned to educate attendees on security concerns facing operators and providers as they move forward with implementing NFV. While the topics are focused on security and are technical in nature we believe any individual responsible for designing, implementing or operating a NFV system in an organization will benefit from this session. Slides here.

NFV Security: Network Functions Virtualization (NFV), leveraging cloud computing, is set to radically change the architecture, security, and implementation of telecommunications networks globally. The NFV Security day will have a sharp focus on the NFV security and will bring together the world-wide community of the NFV security leaders from the industry, academia, and regulators. If you want to meet the movers and shakers in this field, get a clear understanding of the NFV security problems, challenges, opportunities, and the state of the art development of security solutions, this day is for you. Slides here.



5G Security: The objectives of this event are to:
  • Gather different actors involved in the development of 5G, not only telecom, and discuss together how all their views will shape together in order to understand the challenges, threats and the security requirements that the 5G scenarios will be bringing.
  • Give an update of what is happening in:
    • 5G security research: Lot of research is on-going on 5G security and several projects exist on the topic.
    • 5G security standards: Standardization bodies have already started working 5G security and their work progress will be reviewed. Also any gap or additional standardization requirements will be discussed.
    • Verticals and business (non-technical) 5G security requirements: 5G is playground where different verticals besides the telecom industry is playing a role and their requirements will be key for the design of 5G security. In addition 5G is where "security" will become the business driver.
  • Debate about hot topics such as: IoT security, Advances in lightweight cryptography, Slicing security. Privacy. Secure storage and processing. Security of the interconnection network (DIAMETER security). Relevance of Quantum Safe Cryptography for 5G, Authorization concepts....
Slides for 5G Security here.

In addition, Jaya Baloo, CISO, KPN Telecom talks about 5G network security at TechXLR8 2017. Embedded is a video of that:

Does 5G need 'Next Generation' of Internet Protocols?

I have often heard Martin Geddes mention that the Internet is broken, the protocols (TCP/IP) are wrong and if we want to continue the way our data usage is going, we need to define new protocols (see here for example). It was good to find out last week at 5G Huddle that ETSI is already working on this.


The TCP/IP protocol suite has undoubtedly enabled the evolution of connected computing and many other developments since its invention during the 1970’s. Thanks to the development and ubiquity of this protocol stack, we have managed to build an Internet on which we are dependent as a communications tool, an information storage and distribution tool, a marketing channel and a sales and distribution platform, for consumers and for businesses large and small.

However, the industry has reached a point where forward leaps in the technology of the local access networks will not deliver their full potential unless, in parallel, the underlying protocol stacks used in core and access networks evolve. The development of future 5G systems presents a unique opportunity to address this issue, as a sub-optimal protocol architecture can negate the huge performance and capacity improvements planned for the radio access network.

ETSI has created an Industry Specification Group to work on Next Generation Protocols (NGP ISG), looking at evolving communications and networking protocols to provide the scale, security, mobility and ease of deployment required for the connected society of the 21st century.

The NGP ISG will identify the requirements for next generation protocols and network architectures, from all interested user and industry groups. Topics include:

  • Addressing
  • Security, Identity, Location, Authorization, Accounting/Auditing and Authentication
  • Mobility
  • Requirements from Internet of Things
  • Requirements from video and content distribution
  • Requirements from ultra‐low latency use cases from different sectors (i.e. automotive)
  • Requirements from network operators (e.g. challenges with E2E encrypted content)
  • Requirements from eCommerce
  • Requirements for increased energy efficiency within the global ICT sector.


This ISG is seen as a transitional group i.e. a vehicle for the 5G community (and others of interest) to first gather their thoughts and prepare the case for the Internet community’s engagement in a complementary and synchronised modernisation effort.

The ISG provides a forum for interested parties to contribute by sharing research and results from trials and developments in such a way that a wider audience can be informed. Other standards bodies will be involved so that parallel and concerted standardization action can take place as a further step in the most appropriate standards groups.

Andy Sutton, chair of the NGP recently gave the following presentation in 5G Huddle:

5G & Accident Free Driving


ETSI recently held a workshop titled "5G: From Myth to Reality". There were some interesting presentations and discussions, hopefully I will get a chance to write a bit more about it.

One interesting presentation was how 5G will make accident free driving a reality. While the current approach is to use the 802.11p standards that uses the license exempt 5.9GHz band, there is a possibility of enhancements based on 5G


As the final 2 slides say, What could be the use cases for 5G in vehicles? The answer suggested:

  • Map update for highly automatic driving - Instantly update the map of vehicle's surrounding. The challenge of this use case is that the vehicle is currently in the tile that needs to be updated, hence a very quick update is required. 
  • Precise Positioning high speed, no GPS, support for vehicles without high precision location tracking like cars 
  • Audio / Video Streaming (Entertainment) 
  • Online Gaming - side jobs 
  • Sensor- and State Map Sharing (Sensor Raw Data) - Transmit raw sensor data such that others can use their own classifiers to infer decisions
  • Camera and Radar sharing to improve visibility, including See-Through Share sensor information to augment ego vehicle's view. Allows for better visibility in presence of obstructing vehicles, heavy rain / fog, etc. 
  • Short-Term Sensor sharing for crash mitigation - Mitigate crash between multiple vehicle by last-minute traffic exchange 
  • Traffic forwarding using cars as relays Extend coverage or improve efficiency by using the car as a relay 
  • Teleoperated Driving "Let car be controlled by off-site driver / car operator e.g. car sharing, taxi operator, …“ 
  • Augemented Reality, e.g. Daytime-Visibility at night)

Here is the complete presentation, let me know what you think:

Some interesting presentations from ETSI Security workshop


ETSI held their security week from 22-26 June 2015 at their headquarters. There are lots of interesting presentations (see agenda [PDF]); I am embedding some here.


This is a good presentation providing a summary of the reasons for IoT security issues and some of the vulnerabilities that have been seen as a result of that.




The next one is The Threat landscape of connected vehicles and ITS (Intelligent Transportation Systems) integration in general



This presentation provides a good summary of the threats in the connected cars/vehicles which is only going to become more common. Some of these issues will have to be solved now before we move on to the autonomous vehicles in future. Security issues there will be catastrophic and many lives can be lost.

The final presentation is from 3GPP SA3 that provides a quick summary of security related work in 3GPP.

5G and NFV


In my 5G: A 2020 vision presentation, I argued that some of the technologies that will be necessary for 5G is in fact independent of 5G. One such technology is NFV. Having said that, I also argue that the minimum prototype for 5G would require an NFV based implementation.


Tieto gave an interesting presentation in our last Small Cell SIG event explaining how the network will be implemented based on NFV. The presentation is embedded below:



There is also an interesting paper that expands on this further, available from Slideshare here.

NFV and SDN - Evolution Themes and Timelines


We recently held our first Virtual Networks SIG event in Cambridge Wireless. There were some great presentations. The one by the UK operator EE summarised everything quite well. For those who are not familiar with what NFV and SDN is, I would recommend watching the video on my earlier post here.

One of the term that keeps being thrown around is 'Orchestration'. While I think I understand what it means, there is no easy way to explain it. Here are some things I found on the web that may explain it:
Orchestration means Automation, Provisioning, Coordination and Management of Physical and Virtual resources.  
Intelligent service orchestration primarily involves the principles of SDN whereby switches, routers and applications at Layer 7 can be programmed from a centralized component called the controller with intelligent decisions regarding individual flow routing in real time.
If you can provide a better definition, please do so.
There are quite a few functions and services that can be virtualised and there are some ambitious timelines.

ETSI has been working on NFV and as I recently found out (see tweet below) there may be some 3GPP standardisation activity starting soon.
Anyway, here is the complete presentation by EE:



There was another brilliant presentation by Huawei but the substance was more in the talk, rather than the slides. The slides are here in case you want to see and download.

Security and other development on the Embedded SIM


Its no surprise that GSMA has started working on Embedded SIM specifications. With M2M getting more popular every day, it would make sense to have the SIM (or UICC) embedded in them during the manufacturing process. The GSMA website states:

The GSMA’s Embedded SIM delivers a technical specification to enable the remote provisioning and management of Embedded SIMs to allow the “over the air” provisioning of an initial operator subscription and the subsequent change of subscription from one operator to another.
The Embedded SIM is a vital enabler for Machine to Machine (M2M) connections including the simple and seamless mobile connection of all types of connected vehicles. In the M2M market the SIM may not easily be changed via physical access to the device or may be used in an environment that requires a soldered connection, thus there is a need for ‘over the air’ provisioning of the SIM with the same level of security as achieved today with traditional “pluggable” SIM. It is not the intention for the Embedded SIM to replace the removable SIM currently used as the removable SIM still offers many benefits to users and operators in a number of different ways – for example, the familiarity of the form factor, easy of portability, an established ecosystem and proven security model.
















The last time I talked about embedded SIM was couple of years back, after the ETSI security workshop here. Well, there was another of these workshops recently and an update to these information.


The ETSI presentation is not embedded here but is available on Slideshare here. As the slide says:

An embedded UICC is a “UICC which is not easily accessible or replaceable, is not intended to be removed or replaced in the terminal, and enables the secure changing of subscriptions” (ETSI TS 103 383)


Finally, Embedded SIM should not be confused with Soft-SIM. My last post on Soft-SIM, some couple of years back here, has over 15K views which shows how much interest is there in the soft SIM. As the slide says:

Soft or Virtual SIM is a completely different concept that does not use existing SIM hardware form factors and it raises a number of strong security issues:

  • Soft SIM would store the Operator secret credentials in software within the Mobile device operating system - the same system that is often attacked to modify the handset IMEI, perform SIM-Lock hacking and ‘jail-break’ mobile OS’s
  • Operators are very concerned about the reduction in security of their credentials through the use of Soft SIM. Any SIM approach not based on a certified hardware secure element will be subject to continual attack by the hacking community and if compromised result in a serious loss of customer confidence in the security of Operator systems
  • Multiple Soft SIM platforms carrying credentials in differing physical platforms, all requiring security certification and accreditation would become an unmanageable overhead – both in terms of resource, and proving their security in a non-standardised virtual environment

The complete GSMA presentation is as follows:

ETSI Summit on Future Mobile and Standards for 5G



Edited from the original in 3GPP News:

The ETSI Future Mobile Summit has heard how the mobile internet will evolve over the next ten to fifteen years, and how 3GPP systems will ensure future stability as the network copes with an explosive growth in complexity and usage.


With 3GPP providing the evolutionary framework for mobility, via its Releases of new functionality and features, the more radical thinking, at the Summit, came in the form of Research projects and some future focused industry initiatives, such as the WWRF, the METIS Project and the DVB Project.

In his keynote address, Mario Campolargo - of the European Commission - introduced a new initiative on research & innovation that will provide momentum to funded work on research. The 5G Public Private Partnership is being launched as a blueprint for the deployment of 5G, in the years after 2020. 



In summing up the Summit’s main themes, the ETSI CTO, Adrian Scrase identified some certainties; “...traffic will continue to increase, connected devices will increase dramatically over time, new device types will significantly contribute to that increase (e.g., probes, sensors, meters, machines etc) and new sectors will bring new priorities (e.g, critical infrastructures).”

On the concept of 5G, Mr. Scrase reported that ultra-reliable 5G networks should, among other things, enable the tactile internet, the perception of infinite capacity and bring in augmented reality.

What is Network Function Virtualisation (NFV)?


Software Defined Networking (SDN) and Network Function Virtualization (NFV) are the two recent buzzwords taking the telecoms market by storm. Every network vendor now has some kind of strategy to use this NFV and SDN to help operators save money. So what exactly is NFV? I found a good simple video by Spirent that explains this well. Here it is:


To add a description to this, I would borrow an explanation and a very good example from Wendy Zajack, Director Product Communications, Alcatel-Lucent in ALU blog:

Let’s take this virtualization concept to a network environment. For me cloud means I can get my stuff where ever I am and on any device –  meaning I can pull out my smart phone, my iPad, my computer – and show my mom the  latest pictures of  her grand kids.  I am not limited to only having one type of photo album I put my photos in – and only that. I can also show her both photos and videos together – and am not just limited to showing her the kids in one format and on one device.
Today in a telecom network is a lot of equipment that can only do one thing.  These machines are focused on what they are do and they do it really well – this is why telecom providers are considered so ‘trusted.’ Back in the days of landline phones even when the power was out you could always make a call.  These machines run alone with dedicated resources.  These machines are made by various different vendors and speak various languages or ‘protocols’ to exchange information with each other when necessary. Some don’t even talk at all – they are just set-up and then left to run.  So, every day your operator is running a mini United Nations and corralling that to get you to access all of your stuff.  But it is a United Nations with a fixed number of seats, and with only a specific nation allowed to occupy a specific seat, with the seat left unused if there was a no-show. That is a lot of underutilized equipment that is tough and expensive to manage.  It also has a shelf life of 15 years… while your average store-bought computer is doubling in speed every 18 months.
Virtualizing the network means the ability to run a variety of applications (or functions) on a standard piece of computing equipment, rather than on dedicated, specialized processors and equipment, to drive lower costs (more value), more re-use of the equipment between applications (more sharing), and a greater ability to change what is using the equipment to meet the changing user needs (more responsiveness).  This has already started in enterprises as a way to control IT costs and improve the performance and of course way greener.
To give this a sports analogy – imagine if in American football instead of having specialists in all the different positions (QB, LB, RB, etc), you had a bunch of generalists who could play any position – you might only need a 22 or 33 man squad (2 or 3 players for every position) rather than the normal squad of  53.   The management of your team would be much simpler as ‘one player fits all’ positions.   It is easy to see how this would benefit a service provider – simplifying the procurement and management of the network elements (team) and giving them the ability to do more, with less.

Dimitris Mavrakis from Informa wrote an excellent summary from the IIR SDN and NFV conference in Informa blog here. Its worth reading his article but I want to highlight one section that shows how the operators think deployment would be done:

The speaker from BT provided a good roadmap for implementing SDN and NFV:
  1. Start with a small part of the network, which may not be critical for the operation of the whole. Perhaps introduce incremental capacity upgrades or improvements in specific and isolated parts of the network.
  2. Integrate with existing OSS/BSS and other parts of the network.
  3. Plan a larger-scale rollout so that it fits with the longer-term network strategy.
Deutsche Telecom is now considered to be deploying in the first phase, with a small trial in Hrvatski Telecom, its Croatian subsidiary, called Project Terrastream. BT, Telefonica, NTT Communications and other operators are at a similar stage, although DT is considered the first to deploy SDN and NFV for commercial network services beyond the data center.
Stage 2 in the roadmap is a far more complicated task. Integrating with existing components that may perform the same function but are not virtualized requires east-west APIs that are not clearly defined, especially when a network is multivendor. This is a very active point of discussion, but it remains to be seen whether Tier-1 vendors will be willing to openly integrate with their peers and even smaller, specialist vendors. OSS/BSS is also a major challenge, where multivendor networks are controlled by multiple systems and introducing a new service may require risking several parameters in many of these OSS/BSS consoles. This is another area that is not likely to change rapidly but rather in small, incremental steps.
The final stage is perhaps the biggest barrier due to the financial commitment and resources required. Long-term strategy may translate to five or even 10 years ahead – when networks are fully virtualized – and the economic environment may not allow such bold investments. Moreover, it is not clear if SDN and NFV guarantee new services and revenues outside the data center or operator cloud. If they do not, both technologies – and similar IT concepts – are likely to be deployed incrementally and replace equipment that reaches end-of-life. Cost savings in the network currently do not justify forklift upgrades or the replacement of adequately functional network components.
There is also a growing realization that bare-metal platforms (i.e., the proprietary hardware-based platforms that power today’s networks) are here to stay for several years. This hardware has been customized and adapted for use in telecom networks, allowing high performance for radio, core, transport, fixed and optical networks. Replacing these high-capacity components with virtualized ones is likely to affect performance significantly and operators are certainly not willing to take the risk of disrupting the operation of their network.
A major theme at the conference was that proprietary platforms (particularly ATCA) will be replaced by common off-the-shelf (COTS) hardware. ATCA is a hardware platform designed specifically for telecoms, but several vendors have adapted the platform to their own cause, creating fragmentation, incompatibility and vendor lock-in. Although ATCA is in theory telecoms-specific COTS, proprietary extensions have forced operators to turn to COTS, which is now driven by IT vendors, including Intel, HP, IBM, Dell and others.


ETSI has just published first specifications on NFV. Their press release here says:

ETSI has published the first five specifications on Network Functions Virtualisation (NFV). This is a major milestone towards the use of NFV to simplify the roll-out of new network services, reduce deployment and operational costs and encourage innovation.
These documents clearly identify an agreed framework and terminology for NFV which will help the industry to channel its efforts towards fully interoperable NFV solutions. This in turn will make it easier for network operators and NFV solutions providers to work together and will facilitate global economies of scale.
The IT and Network industries are collaborating in ETSI's Industry Specification Group for Network Functions Virtualisation (NFV ISG) to achieve a consistent approach and common architecture for the hardware and software infrastructure needed to support virtualised network functions. Early NFV deployments are already underway and are expected to accelerate during 2014-15. These new specifications have been produced in less than 10 months to satisfy the high industry demand – NFV ISG only began work in January 2013.
NFV ISG was initiated by the world's leading telecoms network operators. The work has attracted broad industry support and participation has risen rapidly to over 150 companies of all sizes from all over the world, including network operators, telecommunication equipment vendors, IT vendors and technology providers. Like all ETSI standards, these NFV specifications have been agreed by a consensus of all those involved.
The five published documents (which are publicly available via www.etsi.org/nfv) include four ETSI Group Specifications (GSs) designed to align understanding about NFV across the industry. They cover NFV use cases, requirements, the architectural framework, and terminology. The fifth GS defines a framework for co-ordinating and promoting public demonstrations of Proof of Concept (PoC) platforms illustrating key aspects of NFV. Its objective is to encourage the development of an open ecosystem by integrating components from different players.
Work is continuing in NFV ISG to develop further guidance to industry, and more detailed specifications are scheduled for 2014. In addition, to avoid the duplication of effort and to minimise fragmentation amongst multiple standards development organisations, NFV ISG is undertaking a gap analysis to identify what additional work needs to be done, and which bodies are best placed to do it.
The ETSI specifications are available at: http://www.etsi.org/technologies-clusters/technologies/nfv

The first document that shows various use cases is embedded below:
