Reflection on Mobile Networks Architectures
Date: 6 September 2016
Place: Lisbon, Portugal
Duration: 1 day
With the increasing pressure for an evolution of the mobile network, several views are being discussed in the academic, industry, and especially standardization communities. It is now clear that the upcoming 5G network, to be standardized by 2020, will not be a fixed static design, since we have to support a wide range of diverse requirements coming from verticals, service providers, and customers. But it will also entail an evolution path, with some design choices dominant on a first stage, and probably reconsidered in later years.
The agreement mostly stops at this point. Some views represent 5G as a radical distributed network, with relocatable functions, almost hardware-independent; others as a more centralized evolution of current 4G architectures, with a more cloud-RAN orientation; others even consider the cloud-RAN as a flexible environment, without a static interface border between the Baseband Unit and the Remote Radio Head functions; others again see an holistic end to end approach covering a huge number of different services as essential to bring radical innovation to network architecture. In parallel with this diversity of views, there is apparently a very different understanding of what a 5G network should be, and what would be the features that it should cover – now and in the future. The distinction between Access and Core is something that is increasingly not clear, as multi-technology access becomes a trend in multiple forms (multi-homing, early breakout, hotspot preference, etc…), and as joint access management is being brought to the system, as core-located virtual functions address access functions as well, and as multi-access trends (such as fixed-mobile convergence) are leading to minimalist functionality on the access network.
This workshop aims to bring together elements actively involved in the design of 5G network architectures, in order to reflect on the different pros-and cons, and provide a fora for joint reflection on the direction of the collective effort the community should try to make. Participants – albeit representatives of different companies and institutions – will be covered during the discussion by the Chatham House Rule.

Working workshop, bringing together elements actively involved in the design of 5G network architectures, in order to reflect on the different pros-and cons. Participants – albeit representatives of different companies and institutions – will be covered during the discussion by the Chatham House Rule.
Session teaser speakers coming from Altran, Brocade, Deutsche Telekom, Huawei, InterDigital, ITU, Juniper, KCL, UCL, ZTE. Sessions are panel-alike, with contributions to the discussion from all participants.
A summary of the conclusions will be provided after the event.

The workshop is organized under the auspices of the CONFIG project (https://www.5g-control-plane.eu/), a joint private undertaking by several companies, including Deutsche Telekom, Huawei, Orange, Interdigital, and Telenor, amongst others.
Location: Campus da Alameda, Instituto Superior Técnico, Lisboa.
Room: Salão Nobre, Edifício Central (central building, Honours Room)

Airport: Lisbon Airport (LIS). Direct metro connection from airport to Campus (Alameda station), around 20 min in the Red Line.
Taxi:taxi stands are available at the airport, transportation will take around 15 min, and cost around 25 euro. Some taxis do have credit card machines, but this is not universal.
Currency: Euro. Major credit cards widely accepted
(5min walk): Holliday Inn Lisboa –http://www.ihg.com/holidayinn/ (select Lisboa hotel, 500 m away from Alameda)
Turim Alameda Hotel – http://www.turimalameda.com/
Hotel As Lisboa – http://hotel-aslisboa.com/
As Lisbon is a major capital, a large diversity of other options are available. The event is near the center of town, and the airport is inside the city limits, so there are possibilities to cater to all tastes. Please reserve your hotel directly.
