Open Airinterface Towards Truly OpenSource Solutions for 5

Open. Airinterface - Towards Truly Open-Source Solutions for 5 G 31/07/2015 Mobile Communications Department Eurecom

Agenda § Testing Methodology – Focus only on openairinterface 5 g but need a similar strategy for openair-CN § Bash script – Compilation, oaisim, § Automated Gitlab CI – Python based for the moment – Migration towards Ju. Ju/Open. Stack based environment § To. Do: – Lionel’s work in openair-CN on scenario player OAI - Open-Source Solutions for 5 G

Testing philosophy of OAI § Split the code in modules § Write module tests for small pieces of the code § Test small modules before committing to develop – Need a definition of modules ? – Some hint provided in slides from Laurent (NOKIA) § Need to develop this further with the team… OAI - Open-Source Solutions for 5 G

Test files location (openairinterface 5 g) § README. txt for overview of all the tests – Openairinterface 5 g/cmake_targets/autotests/README. txt § Test_case_list. xml for description of all the tests – Openairinterface 5 g/cmake_targets/autotests/test_case_list. xml § Log/ dir for output of test results – Openairinterface 5 g/cmake_targets/autotests/log § Test case classes: – Compilation: Test cases to test compilation – Execution: test cases to test oaisim, NAS secuirity tests, dlsim, ulsim tests – Lte-softmodem: test cases for dynamic e. NB/UE/EPC interaction h. EPC can be OAI/Commercial h. UE can be COTS UE OAI - Open-Source Solutions for 5 G

OSA Use Cases OAI - Open-Source Solutions for 5 G

Open-source for 5 G § Economics of mobile are changing towards a Commoditization of RAN – – Cloud SDN/NFV (Op. NFV, Ju. Ju + Ubuntu Open. Stack + MAAS) Emergence of Open. Stack in vicinity of RAN Lots of (cheap) open-source hardware starting to emerge More generic computing equipment right down to PHY (x 86/ARM) (even maybe PHY) h open. BTS, Open. Air. Interface – Canonical (Ubuntu!) providing orchestration and OS solutions (at least for prototyping today) for cellular networks § Example – OAI: Full experimental LTE implementation (Rel 10) h real time and with interworking functions: EUTRAN, EPC, UE h RAN + EPC in Ubuntu Ju. Ju Open. Stack offering! F In a position to provide a full LTE network with Vo. LTE in 2015! Open-source end-to-end (OAI EPC, Clear. Water IMS, Free. PCRF) OAI - Open-Source Solutions for 5 G

Open-source for 5 G § Emergence of hackers in radio networks (or leveraging their work) – § Emergence of fully functional 4 G solutions on equipment that can be bought at the supermarket (almost, with a bit of help from National Instruments or Lime Microsystems) – § Or from Crowdfunding projects (e. g. Novena-RF) Mainstream 4. 5 G/5 G will need cheap, easily extensible devices at the edge (for below 6 GHz systems) – – § Yates. BTS, Fairwaves: deploying commercial 2 G nets based on open-source radio HW and SW small (cheap) form-factor but ubiquitous high-quality RAN access Example: cheap RRH with Cloud. RAN (Rel 12 RRH, 25 d. Bm < 500 euros) commodity Ethernet + 1588 solutions instead of CPRI, sampling synchronization is an issue, but solvable Support potentially of dynamic switching between RATs in the same RRH DSP split between RRH and BBU for fronthaul optimization – – Mobile Edge Computing (ETSI MEC ISG) – provision IT and cloud-computing capabilities within the radio access network (RAN) in close proximity to mobile subscribers h compute/storage able to perform functions such as content delivery, lowlatency Io. T functions h “edge” or at least RAN-aggregate and process Io. T data from a range of media (both cellular and non-cellular) – Mix of cloud and RAN technologies (RRH-to-Data. Center approach) OAI - Open-Source Solutions for 5 G

Next Steps for OAI § Ensure a path 4 G 5 G through open-source policy Reference implementation of Rel 13/14 5 G § Work with new carrier candidates now (e. g. UFMC), short packet low-latency carriers, contention-based access § VRAN, NFV, MEC architectures § Rapidly-deployable EPC/e. NB (with LTE or other backhaul) § Serious contributors from outside Eurecom – Combination of hackers, academics, SMEs and major industry – OAI Software Alliance launched at the end of 2014 § « ready to use » for anybody on commodity hardware (PCs + National Instruments) – and industrial platforms ! § GPLv 3 APACHE v 2. 0 § More global adoption for innovation and research (Vendor labs, University Labs, etc. ) common tool between industrial and academic research – Can also be used in 3 GPP process for study items § Business adoption in test/prototyping market OAI - Open-Source Solutions for 5 G

Anybody can build a 4 G/5 G network Serious contributors from outside Eurecom § Software Alliance (“Fonds de Dotation”) around the current Open. Air. Interface. org development § Make trusted environment – Contributors and users need to secure themselves – Clear open source rules – Any individual person or non-profit organization can become a member for free – Membership conditions for companies § Increase quality & simplify access – Simple and well described binary build procedures for all the LTE components – Friendly to various RF systems (RRH, Small. Cell, etc. ) – Anybody can build a fully open-source 4 G network comprising a couple of e. NBs + EPC for less than 10 K€ and 1 human week of effort OAI - Open-Source Solutions for 5 G

Example Membership Models (a la Open. Stack/Eclipse) § Strategic members – ~100 k€ per year (reduced to 40 k€ with agreed effort) – Strong voice in decision process (limited number of members, e. g. 8) – Ability to run projects (e. g. porting for industrial HW targets) – Ability to attend and host meetings § Associate members – ~10 k€ per year, free for non-profit organizations – limited voice or no voice in decision process (only if merit warrants this) – Use of logo / SW certification – Attend meetings § Ordinary (Individual) members – Free – Main “workforce”, can commit to codebase – Can attend meetings and join projects OAI - Open-Source Solutions for 5 G

OSA Licensing Model § FRAND License allows committing software with patent rights into OSA and still keep licensing rights -> Inline with 3 GPP fair use licensing policy § We are working closely with ETSI for licensing/certification § Future 5 G Core Network developed within e. NB/UE will inherit FRAND license (subject to approval from OSA Board) OAI - Open-Source Solutions for 5 G

Conclusion § OAI is all software, all IP, and open § Integrated tools for a complete experiment life-cycle § Flexibility to architect, instantiate, and configure the network components (at the edge, core, or cloud) – E. g. The network can be packed into a single commodity server/PC or virtualized as a cloud service § Rapid prototyping of 3 GPP compliant and noncompliant use-cases – E. g. Software-define networking or mobile edge services OAI - Open-Source Solutions for 5 G 34
