• Casos de uso 5GSON
- Balanceamento de carga em ambientes Multi-RAT (Multi-radio access
technology) Efficient selection of RAT using SON will lead to better network performance. Both
network assisted , and fully distributed approaches have been reported in literature, with promising
results. Other SON problems that come under this use-case include traffic steering and inter-RAT
handover optimization. the use of directional beams complicates the cell search procedure.
- Direcionamento de tráfego- The key challenge is to enable cell search using highly
directional beams over a large angular domain.
- Compartilhamento e alocação dinâmica de espectro - Automated management and
sharing of spectrum between RANs belonging to different operators is an attractive use-case for
SON.
23. • Outros projetos 5G SON
- Cognet - CogNet aims to research and develop a real-time network management platform
with the capability to scale to address the requirements of the future 5G network.
Applications: Prediction of demand parameters for services and bandwidth ; Creation of ‘on demand’
resources to reflect demand through Network Function Virtualisation; Improving network security
and fraud detection & prevention .
- mmMAGIC- The main objective of the mmMAGIC project is to develop concepts and key
components for a new 5G mobile radio access technology which is expected to operate in a range of
frequency bands between 6 and 100 GHz, here referred to as millimetre wave frequencies. This new
RAT is envisaged as a key component in the overall 5G multi-RAT ecosystem. The project also aims
to accelerate standardisation of mm-wave technologies for 5G so that industry and citizens will
benefit from commercialisation around 2020.
Applications: mmMAGIC technologies will enable a range of extreme mobile broadband services and
applications for mobile users, such as UHD TV and video streaming, virtual reality and ultra-
responsive cloud-based applications. Self-backhauling capabilities are also foreseen, in addition to
access, thereby creating a holistic, scalable and economically viable integrated 5G solution to meet
future needs of operators and users.
