Easy Wireless goals

• Allow service continuity with managed QoS and adaptive service provisioning for mobile users in heterogeneous networking environment

• Strengthen the European expertise and competence in this area of communications

• Pave the way for the interoperability of different networks supporting the transitioning to latest communication technologies


Technical background

• Different network technologies are converging in Europe and globally

• New technologies (hotspots, EDGE, 3G) allow higher data rates enabling new services (VoD, peer-to-peer video, videoconferencing, etc) in wireless networks

• Multimedia services require guaranteed QoS with high bandwidth and low latency

• User acceptance for new services depends strongly on the user experienced quality of the service.

• Future services need to be available wirelessly

• Services need to be trustworthy and easy to use

• Service provisioning must meet the user expected quality


Major results of Easy Wireless

• Open architecture allowing to realise service continuity with managed QoS in heterogeneous network environments

• Demonstrators showing the feasibility and performance of the proposed architecture and mechanisms

• Contributions to networking and communications standards

• Scientific publications

• Increase interoperability between different technologies and improve QoS capabilities in wireless protocols


Work structure

• WP 1 Business model and system requirements

• WP 2 End-to-end quality of service

• WP 3 Mobile service continuity

• WP 4 Interoperability and concept validation

• WP 5 Standardisation and dissemination

• WP 6 Project management


Work of the Finnish sub-consortium

VTT • Develop architecture to measure, test and control the end-to-end

QoS over heterogeneous networks (including cellular access networks, IP core networks, and wireless hotspots)

• Qos measurements• Co-operation of QoS mechanisms in different networks• Congestion control, flow control and scheduling mechanisms• QoS-aware transport protocols for multimedia communications

• Set up demonstration platform with selected network technologies in order to show the performance and feasibility of the architecture

• Vertical handover between 3G and WLAN while maintaining QoS• Real-tíme QoS measurement tool• QoS measurements in cooperation with Nethawk

Nethawk• QoS measurements and analysing methods

Variety ofWCDMAterminals

• Provides access for real WCDMA terminals to Core network and Internet.

• Enables easily the end-to-end service testing in 3G environment.

• Makes optimisation and enhancements of QoS-mechanism in UTRAN and Core network possible without intruding upon public network.

Iub = UMTS interface between radio network controller and base stationGi = Interface between gateway GPRS support node and external network


Participating in the EW project

• Funding already approved in Finland for VTT and Nethawk

• Tekes –funding is 35-50% of the company’s total project costs

• Next funding period: 1.7.2005 – 31.12.2006

• Each partner is responsible for it’s own costs

• Possibility to get extra funding for R&D work, when the topics are in line with the project

• International contacts

• IPR can be protected

• Standardization, the aim is to introduce project results to standardization bodies

• Gather latest knowledge in end-to-end QoS research

• New partners are welcome to join the project any time
