 Basic principles on 5G are work on sufferization, specifically here slicing and virtualization, as well as important area of fixed mobile convergence and ICN for future implementations of future infrastructure. I think indeed we are not the only one working on this. There are many, many groups, other STOs, other for us by industry or other communities, open source as well as important academia and it's in the intention of this workshop to give a snapshot on the current activities ongoing. What we can recognize looking back to two years, the last three years really there was an acceleration of activities related to 5G or like we call it in ITUT and 2020 and these activities have come now from let's say in hype with a lot of nice ideas and expectations down and really focusing on implementable and deployable approaches although here focusing on how to map these expectations to real network structures and network services. This workshop here is co-cited with our repertoire group meeting which will be ended by working party meetings and this Friday the working party meetings I expect that we go for consent for several documents related to slicing to terminology on 5G I guess from ITU the first recommendation related to 5G terminology will be hopefully approved. It's out of my control because the approval is always done by the members not by the chairman and so that will be the starting point but it won't end so we plan several further releases of standards until the end of the year and continuation with work specifically then on focusing on fixed mobile convergence for instance and ICN also in 2018.
