Mobile Edge Computing Overview Mobile Cloud Computing
Mobile Cloud Computing • The computational processing resources are located
in a remote location, e.g., Data Center, and accessed via the Internet.
Benefit • Less capital required by accessing to massive
computing and storage resources.
Limitation • Data transfer bottlenecks subject to access network
issues and delay. • e.g., it is tough to satisfy the 5G latency requirement.

Mobile Edge Computing Overview Mobile Edge Computing
Mobile Edge Computing • Moving cloud infrastructure closer to end
users.
Benefits • On-Premises: The edge is local meaning that it
can run isolated from the rest of the network. • Network efficiency: Reduce the backhaul
usage. • Proximity: Edge computing may also have
direct connect to the devices. • Lower latency: React faster as edge services
run close to end devices. • Location awareness: Local service can leverage
low-level signaling information.

Mobile Edge Computing Overview Feasibility of Mobile Edge Computing
• Cost of storage • As the cost of storage drops, the cost of integration of additional storage also drops.
• Very little storage • Modern APs/Femtos possess very little storage, e.g., 32 – 256 MB Flash is typical.

Mobile Edge Computing Application Active Device Location Tracking
Network measurement based tracking of active • GPS independent and network determined terminal equipment. • Third-party geo-location algorithms within a geo-location application hosted on the MEC
server. • Efficient and scalable solution with local measurement processing and event based triggers. • It enables location based services for enterprises and consumers, for example in venues,
retail locations and traditional coverage areas where GPS coverage is not available. • Services may include mobile advertising, ‘Smart City’, footfall analysis, campus
management, etc.

Mobile Edge Computing Application Augmented Reality Content Delivery
Augmented Reality Application • An Augmented Reality (AR) application on a smart-phone or tablet overlays augmented
reality content onto objects viewed on the device camera. • Applications on the MEC server can provide local object tracking and local AR content
caching. • The solution minimizes round trip time and maximizes throughput for optimum quality of
experience. • It can be used to offer consumer or enterprise propositions, such as tourist information,
sporting event information, advertisements etc.

Mobile Edge Computing Application Video Analytics
Video Analytics • The video management application transcodes and stores captured video streams from
cameras received on the LTE uplink. • The video analytics application processes the video data to detect and notify specific
configurable events e.g. object movement, lost child, abandoned luggage, etc. • The application sends low bandwidth video metadata to the central operations and
management server for database searches.

• MEC server to be transparent to 3GPP network architecture/interfaces
• Application portability • Applications to be seamlessly loaded and executed in the MEC platform. Transfer
of applications between multi-vendor MEC servers
• Security • Fulfil 3GPP security requirements, provide secure sandbox and isolation for
applications. Protection from malicious applications/software and from physical attacks on the MEC server
• Performance • MEC server shall not impair network performance or end user experience
• Resilience • Introduction of MEC server shall not impact network availability. Applications
need to be robust and resilient
• Operations • New management layers for hosting infrastructure, MEC application platform,
and hosted software applications and services
• Regulatory/legal considerations • User data protection/privacy, net neutrality, LI, charging
