2 Networks are increasingly complex 5G foresees a x10 densification of sites compared to 4G Multiple coexisting RATs (2G/3G/4G and 5G) will create interoperability challenges Best user experience demands heterogeneity in access technologies, from small cells to macro cells, licensed & unlicensed, TDD & FDD 5G introduces new challenges in the use of the spectrum: from 700 MHz to 26/28 GHz, with dramatic differences in propagation characteristics (coverage, interference ) The network architecture evolves requiring new ways to deploy and manage our networks through virtualization, efficient orchestration of resources and a combination of pervasive fiber and the best possible radio techniques unlikely to be managed using traditional operation All of them coexisting in our footprint! Indoor & outdoor equipment, with macros & small cells, create a complex heterogeneous environment that presents new challenges for network operation 2

3 Many trends are increasing the Network Complexity Evolution of the RAN Network Architecture Evolution Number of bands (low<1ghz, mid, high>6ghz) Number of radio technologies (2G/3G/4G+5G) Heterogeneity (macro + small/femtocells) Licensed+Unlicensed, FDD+TDD Density of sites, nodes, connections and traffic Separation of control and data planes (SDN) Virtualization (NFV) Cloudification Openess and programmability Service diversity, diverse traffic reqs (slice) Self-Organized Networks SON MANO eson Automatically Orchestrated and Managed Zero-Touch Operations requiring a step change in the Management paradigms 3

13 Automation gains relevance in a scenario of increasing network complexity Network complexity growing due to the Evolution of the Radio and Network Architecture required for massive 5G deployments The SON (Self-Organized Network) functionality has been crutial in the LTE rollout and is evolving from the initial Network-centric solution to a Customer-centric approach and later on to Cognitive solutions The rollout of the Network Cloud Infrastructure needs to accelerate now to allow 5G deployment over common infrastructure with automated SW deployment. The orchestration capabilities need to evolve to handle E2E life cycle management with automatic network configuration. Integrate orchestration capabilities with customer management layer to open new business opportunities such as Network as a Service. Telefonica is already using AI techniques in Telefonica in Service Operation Centers (Argentina, Chile and Germany) for the intelligent management of our networks based on customer experience analysis in real time. These techniques are equally relevant in orchestration. The goal is to have an extreme automation (Zero Touch operation) ready for massive 5G deployments between 2021 and 2025 Enhance network automation by building an AI layer requesting in real time network configuration and adaptations Automation will apply to all Network and Service layers 13
