Applying GENI Principles to LTE Networks

Abhimanyu Gosain and Ivan Seskar

23rd GENI Engineering Conference

17 June 2015


AGENDA

• Intro to Long Term Evolution (LTE)• 5G Foreseen Architecture• How/Where do we apply GENI principles ? (Ivan)

• Open Source EPC (Ivan)• GENI Wireless Campus Deployment• GENI Wireless Monitoring and Operating

Procedures


Intro to Long Term Evolution (LTE)

Application Research Areas:

Public Safety/Emergency Services Backhaul M2M (machine 2 machine) Vehicular safety and in-vehicle applications Carrier Aggregation in Mobile Networks


5G Foreseen Architecture

Source: The vHGW Use Case and Beyond, Pedro Miguel Neves, PT Inovacao,2015


Challenges for software based 5G networks(1/2)

• The end to end Architecture and Design of

a software based network

• What is the Infrastructure for a software based

network? Who owns it and where is it located?

• Combining OpenStandards and OpenSource to deliver value (NGMN,PaaS,IaaS,OPNFV)

• How to ensure the Security of a new network design


Challenges for software based 5G networks (2/2)

Quality of Experience (QoE) improvement by Mobile Edge Computing (MEC)

- User data transactions are processed in local edge network with the computing and cache servers.

- Those functions are moved "Closer" to the edge depending on the service application, mobility, traffic volume and delaySource:” Mobile-Edge Computing – Introductory Technical White Paper” Sep.2014, by ETSI ISG Mobile-Edge Computing”
