Abstract
This document elaborates at an abstract level on the most relevant use cases for the 5G system concept defined by the CONFIG project and that reflects the business interests of the consortium members. It defines functional and performance requirements for the 5G system concept, based on selected use-cases.
Special focus was given to define scenarios for the emerging trend towards network cloudification with network virtualization technologies such as NFV, SDN and context awareness. These scenarios cover selected use cases from areas such as M2M and V2V communications, context awareness, content delivery services, real time media and business applications. These use cases take into account the high capacity, low latency and guaranteed QoS requirements specific to 5G.
Attention is given to scenarios that benefit by the use of edge computing where the network hosts functions running services that are distributed and located in data centres in the local edge. This induces new requirements on the protocols in the networks and datacentres. Furthermore, use cases take into account the fixed-mobile-wireless-broadcast convergence provided by the network architecture in CONFIG.
The use cases act as the basis to derive and define the system requirements for the 5G system concept, also including functional and high level performance requirements as input to the functional architecture and deployment architectures. These requirements cover capacity and latency for wanted QoE and new service delivery time in various scenario settings. The requirements defined in the EU FP7 project METIS1 and the visionary challenges defined for the 5G-PPP2 such as “saving up to 90% of energy per service provided”, “creating a secure, reliable and dependable Internet with a zero perceived downtime for services provision” and “enabling advanced user controlled privacy”
were also important input when defining the requirements.
This work took as input information from various scientific publications, dissemination of previous research projects (e.g. METIS), and other fora, such as the NGMN.
The output of this work is intended for use by other project tasks and work packages covering, a set of selected use cases, as well as system functional and performance requirements that drive architecture and modelling work for a Holistic Converged Network Architecture
