D2.2 1.0Executive SummaryThis deliverable D2.2 describes the BeFEMTO System Architecture, synthesized from the various smallarchitectural evolutions following from the individual concepts developed within the BeFEMTO project.The BeFEMTO System Architecture breaks down into the following sub-system architectures: The BeFEMTO Evolved Packet System (EPS) Architecture, which extends 3GPP’s EPSarchitecture with new functional entities and interfaces. The BeFEMTO Transport Network Architecture, which builds upon a fixed broadband accessnetwork architecture, e.g., the one from TISPAN (Telecommunications Internet converged Servicesand Protocols for Advanced Networking) or BroadBand Forum. This is extended to provide end-toend Quality of Service (QoS) provisioning and authentication a) from the EPS to the customer’spremises and b) inside the customer premises, in particular for the case of networked femtocells. The BeFEMTO HeNB Node Architecture, which extends the internal architecture of traditionalHeNBs with new functional blocks and interfaces for novel radio resource and interferencemanagement (RRIM), Self-Organized Networking (SON), network synchronization, routing andother capabilities. The BeFEMTO LFGW (Local Femtocell GateWay) Node Architecture, which describes thefunctional blocks and interfaces of a new network element that can improve the performance,scalability, and manageability of large femtocell network deployments by providing functionalitiessuch as local mobility management, local breakout, local routing and local RRIM.Apart from describing existing, extended and new functional entities and interfaces of each of these subarchitectures, this report also provides a high-level overview of the various novel technologies developedin BeFEMTO. It also discusses their benefits and limitations relative to other approaches, their impact onthe overall system architecture, as well as their potential impact on standardization.Page 2 (54)

Het aandeel van de ICT-sector is dus gegroeid. — In 2013 realiseerden Nederlandse ICT-bedrijven een lagere omzet dan in 2012. De krimp bedroeg 1,4 procent. Zowel de ICT-industrie, de ICT-groothandel als de ICT-dienstverlening zagen hun omzet dalen in 2013. — In 2012 zorgden ICT-bedrijven voor 5 procent van de toegevoegde waarde

worden aangepakt door de huidige ICT-omkadering. Vanuit het onderwijsveld komt de vraag om het statuut van de ICT-coördinator te versterken en de taakomschrijving van de ICT-coördinatoren te actualiseren. Het is de ambitie van de Vlaamse overheid om de taak van de ICT-coördinator breder in te bedden in een teamgerichte ICT-werking van de .
Regelmatig overleg met de ICT-coördinator over alle relevante zaken betreffende ICT. Het eigentijdse onderwijs waarborgen . Dat de veranderingscapaciteit van ICT van de school ook ingezet wordt. In samenspraak met ICT-coördinator en het team een scholingsplan opstellen. Het bewaken van de opbrengsten van de inzet van ICT.
