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

MEC + MAMS : Unique Value Proposition
• Dynamic Access link information available at MEC using access node interfaces
• Provides overall access resourceutilization 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.

Use case
• 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
• 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.

9. MEC application: video analytics
Use case
• 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
• 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. MEC application: Augmented reality
Create an interactive „wow“ experience
Use case
• 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)
Benefits
• 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)

11. Use case
• 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
• 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

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.
