Network Data Layer

Unstructured – Session Data (UDSF)

Dynamically create, store & share

Any 5G Function & Data Object

Resilient Data storage, distribution for unstructured data – created & updated by application functions across the network – to hold data like authentication vectors, session usage / consumption data, IP-Device association etc.

There is a new way of storing and distributing this information in 5G – call ‘Unstructured Data Storage Function’  which enables many more applications to store and share dynamic data (and leverage it for use cases like network analytics) in a cloud native deployment using a common standard interface across a standard service bus architecture.

Check out the use cases for unstructured data and get out of the operational complexity of each application having a unique approach.

Look at the challenges of storing and sharing resiliently from the perspective of the data and not just the app/function  that created it.

Where Unstructured Data Fits in 5G

Unstructured Data Storage Function (UDSF)

  • According to 3GPP 29.598 (Release 16/Stage3)
  • Maintains session data, which enables any network function and application to be stateless.
  • Data replicated and synchronised (eventual synchronisation)
  • Access control for NFs based on Bind
  • Object size <=10 MB (at present)

Use Cases

  • Data store for NFs providing scale and resilience
  • Data sharing for application functions
    • Notification of change from NFs
    • Applications using data do not need access the source Network Function instances directly – they can harvest data from a copy

Stratum Network Data Layer is the perfect cloud-native, resilient storage and distribution layer to reduce the complexity of each application storing their own data their own way!
