Jose Costa-Requena received his Master Sc. in Engineering (MSc.) in 1999, his Licentiate in Telecommunications Engineering in 2004 (Lic. Sc.) and his Doctor in Engineering (Dr.-Eng.) degree in 2007 from Helsinki University of Technology. From 1998 through early 2009, he worked as a research staff at Helsinki University of Technology focusing on mobile networks, routing, security and adhoc networking (ADD A BIT MORE ON THE RESEARCH AREAS) publishing several journals and articles in the field of computer networking.Since 2009 he has been a research manager leading EU telecommunication projects partnering with major companies and operators while also teaching networking at Aalto University.
He is currently a Research Manager in the Department of Communications and Networking in the Faculty of Electronics and Communications and Automation at Aalto University (
www.comnet.aalto.fi).He is interested in mobile networks, Ad-hoc and opportunistic networks, network security, green ICT and energy efficient data centres.
He has been managing the ICT Labs SDN activity with 5 other international partners at the European Institute of Technology (EIT;
http://www.eitictlabs.eu/) The objective isto define the use of Software Defined Networks (SDN) in mobile access networks. Dr. Costa-Requena also lead the architecture work package of EU project under CELTIC framework, MEVICO with 20+ international participants and the objective of defining next generation mobile network architecture. The project won silver award (

Dr. Costa-Requena was simultaneously working in industry gaining 10+ years of experience in system architecture and product development for world market products. He worked for Nokia Mobile Phones and Nokia Networks as Senior Design Engineer from 1999 to 2001 where he contributed to 3GPP standardization (CN1-Core Network WG, SA3-Security WG and SA2- Services/Applications WG in 3GPP, www.3gpp.org). The main contributions where in the 3G core network architecture and integration of packet networks including SIP, Presence, messaging and Location Services in 3GPP Release 99 up to Release 8.
In addition to standardization Dr. Costa-Requena was acting as System Program Manager until 2009 in Nokia Software & Services where he managed the Remote Home Access (RHA) system program. He defined RHA architecture; managed the R&D team formed by 11+ subcontractors and 100+ developers to develop components in S60, Linux, Windows and Linux.
His enthusiasm for innovation resulted in high contribution to Nokia IPR portfolio. Currently he holds 15+ granted patents and 40+ filed applications in the area of local area networks and mobile networks and received award of top 3 inventor of the year. Morover, Dr. Costa-Requena was a respected member of Nokia patent board for several years.
His research interests are wide covering Internet technologies, green ICT, energy efficient data centers, mobile networks (i.e. 3G, LTE), protocol design, system architectures for multipoint communications, content distribution, IP telephony, and multimedia conferencing.
Softwarization of Mobile Networks, the Next Processing Platform - What is beyond 4G?
This tutorial provides an overview of the Software Defined Networks (SDNs), Long Term Evolution (LTE) mobile networks and Network Functions Virtualisation (NFVs) as the driver technologies leading mobile networks beyond 4G. SDN together with NFV are decoupling forwarding from control and hardware from networking software, using open interfaces to connectivity resources. Softwarization of Mobile network elements enables them to be offered as service. The Softwarization will transform the walled garden LTE mobile networks into commoditized components that can run from the cloud. Moreover, Softwarization simplifies not only the management plane in centralized location but introduces also a disruption in the access network but also transport plane after removing mobile specific technologies. This will lower the entrance barrier to mobile network manufacturers and operators. The Softwarization will facilitate the deployment of mobile optimized services such as video streaming and caching that can be used for new revenue models to mobile service providers. The tutorial finally provides some scenarios on how future mobile networks based on SDN and NFV introduce new business models.
