1  ScopeWord‑p. 6

Emerging from the FS_SMARTER work [2], the present document aims to identify and document the key families of use cases and their consolidated potential requirements, and to capture desired system requirements and capabilities to enable 3GPP network operators to support the needs of new scenarios and markets related to network operation.
The focus of this work is on the use cases and requirements that cannot be met with EPS.

4  OverviewWord‑p. 7

Among the use cases developed in the SA1 FS_SMARTER study [2], there are a group of use cases which are particularly related to network operation.
This group addresses the functional system requirements, including the following aspects:
  • Flexible functions and capabilities
  • New value creation
  • Migration and interworking
  • Optimizations and enhancements
  • Security
Emerging from the SA1 FS_SMARTER work, the present document documents the key families of use cases and consolidates the potential requirements for the following families for network operation:
  • System flexibility
    This family covers the use cases for building the network in a flexible manner per diverse scenario demand, e.g., slicing the network for variant market segments and verticals.
  • Scalability
    This family covers the use cases for enabling the operators to support an elastic and scalable network.
  • Mobility support
    This family covers the use cases for optimizing use of mobility management for diverse scenarios.
  • Efficient content delivery
    This family covers the uses cases to support efficient content delivery.
  • Self-backhauling
    This family covers the use cases for wireless self-backhauling.
  • Access
    This family covers access related use cases including selection of the most appropriate access for user traffic.
  • Migration and interworking
    This family covers the coexistence of the FS_SMARTER system with the legacy systems and the migration of services from early generations.
  • Security
    This family covers security requirements that are common to all building blocks as well as the ones that are specific to network operation.
