  7. 7. 7 © Nokia 2017 Multiple Access Management Services (MAMS*) and MEC Loose coupling, Optimal path selection, Flexible user plane treatment • Allows lightweight integration of different access technology domains. • Example applications: • Synergetic use of cellular network and local Wi-Fi network for optimum quality of experience to enterprise and cellular applications without impact to LTE and Wi-Fi access infrastructure • Allows combining MEC applications with high capacity local radio access for all venue visitors. • Asymmetric Access link selection in UL and DL (e.g. LTE UL for extended Wi-Fi/5G DL usage) • Dynamic and per-user best path selection based on network policies and link quality measurements on user devices. • Any access (5G/LTE/Wi-Fi) integration for enterprises, public venues and stadiums. • Flexibility in choosing and dynamically adapting user plane treatment per traffic type Benefits Use case CCM C-MADP LTE 5G Small cell WLAN MEC Enterprise 5G core LTE core NCMN-MADP • Dynamic Access link information available at MEC using access node interfaces • Provides overall access resource utilization view and network information like PRB utilization, Handover Preparation, Congestion, CPU overload not available via individual UE reports • Real time reporting without impact to device and radio link resources • RNI (Radio Network Information) API which augments MAMS traffic management performance by real-time radio information based analytics. MEC + MAMS : Unique Value Proposition *draft-kanugovi-intarea-mams-protocol-05
  8. 8. 8 © Nokia 2017 Use case MEC application: throughput guidance for an optimal video experience Developed and tested with Google, proposed for standardization to IETF Real time upstream guidance OTT source Optimized downstream delivery eNodeBs • Best video experience as a differentiator • Optimal use of network resources (including the air interface); video delivery doesn’t choke the pipe • Simple and completely non-intrusive optimization, also for encrypted content. • Computes real time throughput guidance for individual user connections • Guidance is sent within upstream user packets, no extra signaling is required • Largely eliminates the inefficiencies in mobile delivery today, which are caused by sources being unable to gauge network capacity Benefits Ref • draft-sprecher-mobile-tg-exposure-req-arch • draft-flinck-mobile-throughput-guidance
  9. 9. 9 © Nokia 2017 MEC application: video analytics • Full video monitoring system with pluggable analytics modules, allowing allow real-time correlations and actions • The analytics software supports different use cases and can be easily adapted to different customer needs. • Example: MEC is used for analyzing raw video streams from surveillance cameras connected over LTE, and for forwarding the relevant incidents to the city command center. The camera streams can be broken out to the local control room. Benefits Use case • LTE-connected cameras provide lower cost of deployment and greater flexibility, even for temporary events • Reduces latency and relieve the burden on backhaul • Video traffic stays local to comply with regulatory and legal requirements
  10. 10. 10 © Nokia 2017 MEC application: Augmented reality Create an interactive „wow“ experience • Quickly determine user location based on network data • The local augmented reality (AR) server (running on a MEC host) performs fast image recognition and subsequent delivery of local AR contents. • Automated content refresh between content on Mobile Edge Computing and AR origin (cloud) Small cell / Wi-Fi AP • Enables unique experience with an unmatched degree of interactivity • Spontaneous discovery and delivery of locally relevant AR content in public spaces (e.g. stadiums, malls, airports and train stations) AR originEPCMEC Benefits Venue Use case
  11. 11. 11 © Nokia 2017 Use case MEC application: Connected cars Source: See more: • Can satisfy the tight latency requirements of connected cars communication which is particularly important for traffic safety applications. • Helps to improve road safety, efficiency and comfort • New applications and service providers • The MEC application used as a roadside unit for car-to- infrastructure and enable real-time communication between cars via the LTE cellular network. • Road hazards (hand brake, accident, etc.) can be recognized and warnings can be sent to nearby cars with extremely low latency. • Enables a nearby car to receive data in a matter of milliseconds, and the driver to react instantly. Benefits The first public showcase of safety applications took place at the "Digital A9 Motorway Test Bed“ (November 2015)

A different set of services may be applicable at different locations A framework for delivering services which may be consumed or offered by (locally hosted or remote) authorized applications. It enables: • registration, announcement, discovery and notification of services; • authentication and authorization of applications providing and consuming services; • communication support for services (query/response and notifications). A set of API principles and guidance for developing and documenting APIs inside or outside ETSI which ensures that a consistent set of APIs are used by developers. The work was inspired by the TMF and OMA best practices. The APIs are designed to be application-developer friendly and easy to implement so as to stimulate innovation and foster the development of applications.
