            NFV Release 3 features are defined matching market demand and associated work items have been studied
            including, Charging, billing and accounting, Policy management, End-to-end management, Multi-site NFV
            services, VNF lifecycle management and so forth.
            6.1.3   Standardization activities at ETSI ISG MEC

            The future broadband networks need to cover wide range of key use cases from ultra-low latency services to
            massive  IoT.  In  order  to  respond  to  demands  on  expected  throughput,  latency,  scalability  and
            programmability, ETSI established an Industry Specification Group on Mobile Edge Computing in 2014.

            ETSI  ISG  MEC  develops  a  standardized  and  open  environment  that  offers  distributed  cloud-computing
            capabilities and an IT service environment to application developers and content providers. By February
            2016, the group has finalized three stage 2 specifications: Terminology, Technical Requirements and the
            Framework and Reference Architecture. Currently the ISG works on specifications of the following work
            items:
            •       MEC platform Application Enablement;

            •       MEC API principles and guidelines;
            •       MEC  Services  APIs  for  Radio  Network  Information,  Location,  UE  identity  and  Bandwidth
                    management;

            •       MEC system, host and platform management;
            •       MEC lifecycle and policy management;
            •       MEC UE application interface;
            •       Deployment of MEC in a NFV environment;
            •       End-to-end Mobility

            By offering distributed cloud-computing capabilities and exposure to real-time radio network and context
            information, the MEC environment is characterized by:
            •       Ultra-low latency: Mobile Edge services can be run close to the end user devices to provide the
                    lowest possible latency

            •       Proximity: Being close to the source of information, Mobile Edge Computing is particularly useful to
                    capture key information for analytics and big data
            •       High Bandwidth: Mobile Edge location at the edge of the network combined with the use of real
                    time radio network information can be used to optimize the bandwidth for the applications
            •       Location awareness: Mobile Edge can leverage the low-level signalling information to determine
                    the location of each connected device
            •       Real time insight into radio network and context information: Real-time network data can be used
                    by the applications and services to offer context-related services.
            MEC can bring significant improvement of mobile user’s Quality of Experience on latency or QoS sensitive
            services.  The  example  use  cases  include  Edge  Video  Orchestration,  Mobile  Video  Throughput  guidance,
            Augmented reality, Intelligent Video Analytics, Vehicle-to-Infrastructure (V2I) communication etc.
            MEC enables the implementation of mobile edge applications as software-only entities that run on top of a
            virtualisation infrastructure, which is located in or close to the network edge.
