 Yeah, welcome to Osmo Defcon 2018. I'm very happy to see lots of familiar and some new faces. This is just a quick intro. The slides are for our original venue in Berlin. So if there's some things that don't apply from the slides to this venue, but let me just quickly introduce the venue. We are here at Chaos Computer Club Berlin, which is a German hacker organization established in the 80s. And this is the Berlin subsidiary. We are here as guests. As everyone who has arrived here knows, there is the bomb diffusing happening near the normal venue in Berlin. There is a refrigerating machine where you can get drinks such as Club Marta from. There is a fridge back beneath the bar. Each drink is 1 euro 50. There is a box for you to put the cash in if you grab some drinks. There are some apples I brought. They are free. We have cookies. They are here. And the washroom is back there. So if you see the small door left of the bar, if you follow that door straight ahead is a shower. I think maybe not the place you want to go and slightly right of that there is washrooms. The downstairs area is normally members only. So unless we have good reasons to have a separate group in the downstairs floor, we should remain upstairs here. And particularly there are some sensitive devices down there such as an electron microscope. Don't play with it. Only after introduction by people familiar with the equipment, which I am not. So there is nobody here who can help you with that. So otherwise there is a Wi-Fi network that is called Geeks External. That is open so you can just register there. There are also Ethernet cables everywhere coming from the wall, not everywhere, but in some places you can just use that to access the internet. We have distributed power sockets everywhere so you should have power. If you need anything else, ask me or Philip back there, Dexter, who is also familiar with the venue to some extent. So 2018 means this is the seventh incarnation of OsmoDevCon, the OsmoCon Developer Conference. The project started in 2008 so we are reaching almost our 10-year anniversary now, but the Developer Conference only started a few years later. It's really good to see all of you as old regulars as well as new people. OsmoDevCon is by developers for developers as technical as it gets, and it's at least as much about the people who work on the code as the actual topics. So we've always had a tradition of if somebody is working on something interesting, even if it's not OsmoCon related strictly speaking, we are more than welcome to such talks. There are some topics maybe that are not classic OsmoCon. So if anyone still has something interesting that he's working on that he wants to share, I'm sure we can still find a time slot here or there to talk about that if there's something that's exciting technology that you would like to share. I think lots of interesting or interested like-minded people are around here to hear about that. Yes, and any reasonably advanced technical topic is indistinguishable from magic. No, but it's welcome. As far as time permits of course. So in the venue over there, in Berlin we have various different rooms. I'll skip that. So we have also some coffee here, some milk, we have tea making facilities. There's the beverages in the fridge. You can access Wi-Fi and Ethernet, what I already mentioned is also a set of slides were made for in Berlin, not for here. So looking back at last years of OsmoDevCon, there was some criticism. We didn't have a lot of time for hacking and chatting. There was lots of talks last year and very little time for the unstructured part, like I called it this year, in 3GPP speech. And so we extended the time again to four days. Last year OsmoDevCon was only three days. Now it's four days again, so we have more time. And the idea is also to, in Berlin, we have changed the seat arrangement from last year in a way that the second room where people only start their luggage in previous years still has a table inside. And so if some people want to hack on something and skip a couple of talks, they can basically move there and still have a collaborative atmosphere with a desk and Ethernet and even a separate projector if needed. So that's the idea. We also have video recordings that are optional, of course, this year for the first time. The idea is that at least some of the topics I think are interesting to a wider audience. And it's good to share them. We got extremely good feedback about the video recordings at OsmoCon, the user conference last year. There was lots of positive feedback and even we can still point people to that. So if we get questions, we can say, oh, you know, this was covered in the talk. Look at that video and get up to speed on this related topic. What's also new is that we have a real schedule which sort of relates to the previous two topics, rather to the video recording topic and the more time or more structure for that. In order to have time for hacking and chatting, we don't have any formal schedule after dinner every day. And also the lunch break is quite long if I recall it in the schedule. So there should be some time. And yeah, so I hope this year we have more time for the informal part than we had in previous years or the unstructured part. Yeah, so in terms of sponsoring lunch and dinner as covered by OsmoCon, the venue and internet were in Berlin. It's in Berlin who is providing that. Here is the CCC Berlin. I'm very thankful for having been able to use those venues. We have video recording by C3Voc. The video operation center of the CCC, which is doing recording at the Chaos Communication Congress at EasterHack at many other conferences. We don't have somebody here to operate the equipment, but we have the equipment here and operated ourselves. We don't have live streams. We only have recordings. And every speaker of course can decide whether he or she, well only he in this case, wants to have the talk recorded. So please make that clear before at the beginning of your talk and then we can make sure that this is not recorded and or not published. Even after you gave a talk, since it's not live streaming, we can still prevent it from being released or published if you have the feeling that this should not become published. Yeah, we have some guest presentations this year outside of the OsmoCon community. There is Suk Chan Lee back there from South Korea who has been working restless on NextEPC over the last year or so. He will introduce NextEPC to us, which as the name implies is an EPC and evolved packet core for LTE as open source implementation. We also have two speakers from Lime Microsystems on Sunday. If I'm not mistaken, to speak about adaptive digital pre-distortion on Lime SDR as a guest presentation. And sorry, the figure is wrong. Actually we received 50 in Lime SDR Mini donated from Lime Microsystems. They are at Inverlin of course and not here. So tomorrow we can distribute them to interested developers for free. Yeah, thanks to Lime at that point. And that brings me to the end of file for this presentation. And we can continue shortly with the presentation by Niels on the one year after the NITP split. But before we do that, maybe just a quick, if you have some questions about the venue, about internet, anything unclear, anything you need, let me know. No? Okay, good. Yeah, let's have a quick look at the schedule. This is the schedule as it's on the free talks website. So we have Niels talking about the NITP split. Then we have a break. We have a block about MGCP Media Gateway and IUUP user plane. Then we have the two hours of lunch break. Hopefully if the food delivery company, they confirm the new address, but I hope they will actually also deliver it to here and not try to deliver it to the bomb defusing site. Then we have sandwiches and salads. There's some more details about the food if you click on the respective schedule item. And then later on today we talk about getting back to E1-based addresses, back to the roots. And some talk about USSD, load-based handover, and counter, rate counters, statistics items, followed by sort of a retrospective about my experience or my result of what happened the previous year or the last 12 months. And we will go for dinner at 8 p.m. We should leave earlier, but we should be there. We should reach there by 8 p.m. So we should leave by 7.30 p.m. here at Chinese restaurant, which is a few local train stops away from here. So we will, as a group, go to this restaurant and have dinner there. And that's it basically for today. And tomorrow morning we then meet in Berlin at 10 a.m. for those who want a TTCN3 for breakfast. And yeah, okay, good. Then if you don't have any questions, I'll hand over to Niels for his talk on the NIPP split. Thanks.
