Your media everywhere, anytime. This summarizes end-user expectations when ever-wider broadband and ever-lower flat-rate tariffs combine with users’ thirst for digital content.
The authors describe Ericsson’s end-to-end solution for remote access services, which builds on the IMS and UPnP families of standards, along with the Home IMS Gateway (HIGA), which serves as an intermediary gateway for connecting the device-centric consumer electronics space with the user-centric telecommunications world. The gateway approach leaves
the consumer electronics and telecommunications business models unaffected, while at the same time creating synergies between the two.

We live in the age of the digital packet. Documents, images, music, phone calls all get chopped up, propelled through networks, and reassembled at the other end according to Internet protocol. So why not TV? Today, IPTV (Internet Protocol Television) is creating headlines all over the world. This mass publicity is the result of numerous instances and stories depicting its humble deployments and its future. IPTV is a very useful system, through which you can receive both TV and video signals along with other multimedia services by means of your Internet connection. In nutshell, it is nothing but a broadband connection and a system to deliver various programs of television using the Internet protocol (i.e., language) over computer networks. It is important to remember that IPTV is not like any ordinary television program broadcast through the Internet, but rather it is unique in itself. Its contour is represented by a closed, proprietary TV system which is similar to the cable services present today. But, in contrast, the delivery of IPTV is made via IP-based secure channels, which result in a sharp increase in content distribution control.

Head to Head - The Battle between the Bellheads and the Netheads for control ...Pieter Geldenhuys
Part 1: When the infrastructure is ubiquitous and operates as a utility, like water or electricity, we will move beyond the current paradigm of cyberspace. What happens when information and knowledge are accessible to all who choose to look? What happens when eBusiness, eHealth and eLiteracy have become an invisible normality? What happens after the Ubiquitous Internet has irreparably changed our very understanding of the world we live in? A new Digital Value Chain will be required when the Netheads and Bellheads pit their business models against each other in an epic battle where the only winner is bound to be the consumer. Who will find the right balance between the investments required to support the infrastructure and the money that inevitably will flow to edge of the network where the intelligence and power resides?

These documents present the conclusions of the study “Leveraging ICT for the BoP” sponsored by AFD-Proparco, Ericsson, ICCO, France Telecom-Orange, and TNO and conducted by Hystra and Ashoka from October 2010 to June 2011. This study aimed to learn from “what works” in terms of full projects (as opposed to technologies) combining both an economically viable model and socio-economic impacts on their end-users, in the field of ICT for development (ICT4D). This work is thus based on the screening of existing projects led by various types of actors (social entrepreneurs, NGOs, private companies…), in 4 sectors of “development” where ICT has already shown it could play a key role: healthcare, education, agriculture, and financial services. 15 of the most ground breaking market-based business models, with a proven scale and results on the ground showing that ICT can be a lever improving the living standards of the BoP, are analysed in depth in the report to support the main conclusions.
We hope that this report, like ICT itself, will not be an end but part of the means to create more effective approaches to foster development.

Sustainability and Corporate Responsibility Report 2010 – Technology for GoodEricsson France
To mark the launch of Ericsson’s Sustainability and Corporate Responsibility Report 2010 – Technology for Good, we hear from company President and CEO Hans Vestberg on the significant role of sustainability in the Networked Society. He also outlines the company’s sustainability priorities for 2011.
Technology for Good is the theme of the latest Ericsson Sustainability and Corporate Responsibility report. It highlights the company’s ongoing efforts to apply innovation to market-based solutions that empower people and society to help create a more sustainable world. These efforts are central to the transition to the Networked Society – a world where everything that would benefit from being connected will be connected.
Vestberg addresses what he calls the three pillars, which will facilitate the sustainable transformation to the Networked Society: connectivity technology itself; the global reach of existing networks; and the socio-economic benefits delivered by broadband technology.
He talks about how solutions targeted at different sectors – such as consumers, institutions or enterprises – build on the three pillars, with resulting benefits for society and sustainability.
Vestberg also talks about his three sustainability priorities for 2011:
- Developing scalable market-based solutions (in sectors such as health care and education) that can be replicated, preferably on a global scale
- Maintaining Ericsson’s sustainability leadership position, incorporating company ways of working with Ericsson products
- Being a voice for the role of sustainability and Technology for Good in the Networked Society through advocacy with stakeholders such as customers, governments, ICT players and other industries.
In his introductory letter to the Sustainability and Corporate Responsibility Report 2010 – Technology for Good, Vestberg says broadband and mobility are revolutionizing the way health care and education are being provided.
"As a catalyst for more sustainable development, we have only begun to tap the possibilities of the Networked Society," he says. "The transformational power of ICT to spur socioeconomic development and put us on the path to a low-carbon economy has never been greater."

Ericsson white paper - Device connectivity unlocks valueEricsson France
Device connectivity unlocks value – operator opportunity in an emerging business environment
New revenue opportunities are emerging for mobile operators through the delivery of machine-to-machine (M2M) and consumer-device connectivity services, which add value for enterprises and consumers. Maximizing revenues in this area demands a cost-efficient, flexible approach that enables a high degree of differentiation and customization.
The world is already highly connected and it's about to get even more so: today, there are about five billion mobile subscriptions worldwide. As devices of all kinds become connected, there will be more mobile subscriptions than people on the planet. Ericsson envisions an increase in the number of connected devices by a factor of ten over the coming decade.
The mass market for M2M and consumer device connectivity is growing fast and represents an enormous opportunity for mobile operators who can address the challenge of delivering cost-effective and customized connectivity with minimal process costs.
A broad range of industries will deploy connected devices; everything from transport and health care, mining and agriculture, to manufacturing and commerce (in areas such as point of sale, vending, remote information displays and digital signage).
To serve the divergent needs of these different segments, operators will need provisioning systems capable of handling very large numbers of connections, as well as infrastructure with QoS mechanisms that can handle massive amounts of simultaneous differentiated sessions.

Etude exclusive Ericsson sur la TV : la consommation “on demand” et payante va nettement s’accentuer
Le marché de la consommation de contenus télévisuels va continuer de connaître des transformations radicales. C’est l’un des enseignements majeurs d’une étude dévoilée le 26 août par le Consumer Lab d’Ericsson lors d’une conférence de presse à Londres. Les principaux leviers du changement proviennent de la télévision par Internet (IPTV), des tablettes tactiles et d’une consommation de contenus à la demande. L’étude estime également que les contenus payants seront en hausse dans un avenir proche si la qualité et la facilité d’usage sont satisfaits. L’étude reflète les résultats de 7 marchés majeurs équivalant au total à 300 millions de consommateurs.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

UPnP Remote Access specifies mecha-
nisms that make it possible to extend the
home network so that it logically includes
remote devices outside the home LAN. De-
vices may thus communicate among them-
selves using UPnP procedures (specified, for
example, in the UPnP Device Architecture).
The main functional components of the
UPnP Remote Access architecture are the

and
• Remote Access Discovery Agent (RADA).
These two components are applied in both

4. INVITE message to HIGA, which au-
thenticates the request by comparing the
P-Asserted-ID (inserted by the home opera-
tor in the INVITE message) with the values
of allowed user identities. In short, home ac-
cess control is delegated to established IMS
mechanisms, whereas the user (Mr. Martin)
maintains control of the access control list.
Optionally, the operator backend can man-
age access control and operation.
The session description protocol (SDP) in-
cluded in the IMS signaling, is used to in-
form the RAS and RAC of the IP addresses
and ports for the remote access tunnel. It is
also used to negotiate VPN profiles and the
key management protocols used to establish
the tunnel. This negotiation ensures agree-
ment on a common secure mechanism sup-
ported by both HiGA and the remote client.
It also allows for continuous updates as new
security schemas emerge.
Phase 2: Peer-to-peer VPN setup over Figure 3
the IMS media plane Main flow for session set-up between remote device, HIGA and home NAS.
Once Mr. Martin is successfully authenticat-
ed and authorized, the remote client sets up
a secure media control session between itself
and HIGA.
For tunnel setup, UPnP Remote Ac-
cess specifies an out-of-band connection-
establishment procedure. Ericsson’s solu-
tion employs a corresponding connection-
establishment profile based on operator-
managed IMS network procedures, with
HIGA functioning as the VPN server. After
tunnel setup, the connection between Mr.
Martin’s remote device and the NAS in the
home network appears as a local UPnP con-
nection.
Phase 3 – UPnP discovery
Because UPnP was originally designed for BOX B, HOME IMS GATEWAY
use in local area networks, there are some
challenges associated with extending it for The Home IMS Gateway (HIGA) is a logical function that collects information about users, de-
use in wide area networks. For example, vices and services in the home, and manages IMS sessions on behalf of non-IMS-capable home

HIGA is registered to the IMS core based on secure authentication, for example, using a soft

UPnP Remote Access solves this by filtering tain a SIP UA, such as a VoIP phone, can directly register with HIGA. The B2BUA then translates
relevant messages in the remote access server SIP control signaling into IMS-specific messages that it relays to the IMS core.
For IP devices, such as DLNA-compatible media servers and renderers, a SIP UA inside HIGA

unicast. (optionally) a UPnP control point for QoS policy control in the home network.
By applying the standard UPnP RADA HIGA functionality can be deployed anywhere in a user’s home network. From a practical per-
mechanism for synchronizing Mr. Martin’s spective, it is easiest to co-locate it with the user’s residential gateway (RGW) – that is, with the
