InterDigital Europe, Ltd. – Open for business July 2013


� Central mission is to drive technology collaboration & partnership initiatives across the European stage

� Happy to call London and “Tech City” our home affording us easy access to anywhere in Europe

� We play in Horizon 2020, 5GPPP, Innovate UK and are always looking to create new projects and alliances

� Already seeing some good results with four wins in EU competition (e.g. H2020) so far

� Also driving a integrated transport initiative, “oneTRANSPORT” in the area of the IoT

Key Aspects

• Rapid change of constraints

• From data-at-rest to data-in-motion within milliseconds

• Dynamicity of control

• Need for integrating other infrastructures

• Controlling the previously unknown

• Dynamicity of controllability

A single provider CANNOT own all possibly required infrastructure!


Paradigm Shift at the Control Level:Controlling Assets You Don’t Own

Service provider PropertiX provides a building management service to tenant

Lexxor, utilizing advanced monitoring and actuator infrastructure embedded

into the physical membrane of the building. With this, the control centre of

PropertiX can determine if the overall state of the building is safe and sound as

well as, in case of disturbances, determine root causes and audit

malfunctioning.

At some point, an emergency occurs when a construction vehicle, operating

outside the building, crashes into a large part of the building. The smart

environment of the building senses the relevant information and signals an

emergency alert to the control centre.

As a reaction, the control centre reconfigures the settings for data collection

and aggregation in order to retrieve auditable and comprehensive status

information from relevant building areas. Furthermore, the breakage of a

physical part of the building triggers an emergency procedure. For this, the

control centre provides access to the building infrastructure towards the

emergency services, helping in assessing the structural damage and

optimizing the access of rescue workers.

POINT: The technology solution for competitive 5G operator networks

• Aligns introduction of ICN concepts with evolution of single network upgrades

• Preserves perception of IP services but with novel routing at control levelFunded under H2020 POINT grant #643990

Conclusions

• 5G breaks with crucial paradigms in <5G

• Control across resources you do not own

• New solutions beyond SDN only required

• Deal with dynamics and the unknown

• Exciting propositions ahead

• Not only new services but also making current ones more profitable
