2 Outline TIM approach for SON Some (consolidated) requirements Targeting 5G First set of SON use cases Conclusions 2

3 TIM s approach for SON Advanced optimization and network development applications Supporting Wireless innovation: simulation of new technologies and features deployment, based on early vision mainly derived by research and standards Exploiting in house development: continuous enhancements and customizations based on feedback and requirements coming from Operations. Gaining a competitive advantage: appications based on TIM proprietary algorithms and models TIMPLAN (Radio Access Design) LTE-A carrier aggregation analysis example TIMQUAL (Radio Access Optimization) KPI geo-location example 3

4 Open SON PoC: ANR control and PCI/RSI optimization Open SON Proofs of Concept were carried out in several areas (with different RAN technologies and different SON providers). Focus was on process improvement. Use case example: ANR control + PCI/RSI Optimization process, involving D-SON, C-SON (acting as a mediator) and operator s tools. PCI/RSI configuration is based on NBR lists (managed through TI tools) NBR are automatically optimized (in real-time) by D-SON ANR feature Coordination by C-SON providing direct information exchange between the modules White lists and black lists configuration can be used to periodically control ANR behaviour (e.g. avoiding long distance NBRs) Process target: minimization of failed HOs (beneficial for VoLTE). 4

5 RAN Virtualization TIM Tests Virtual Radio Access Network Technology In Turin, TIM first in Europe and among the first companies in the world successfully tested Virtual Radio Access Network (vran) technology, which will improve the quality of the current mobile network, increase efficiency and prepare for future 5G. vran solution provided by Altiostar of Massachusetts (USA), was tested in the Turin TILab laboratories, demonstrating the first wireless access implementation providing centralisation and virtualisation of radio signals, even with Ethernet fronthauling [ ] In this context, an open architecture was also defined for the development of SON (Self Organising Network) functions for automatic network configuration, which uses innovative operative and working methods with the design tools developed by TIM. (Press release announced at MWC 2016) Joint tests on Open SON framework are ongoing, exploiting Altiostar API 5
