Unstructured Data Storage Function for 5G Core Network.

The 3rd Generation Partnership Project (3GPP) created a data storage architecture to create a truly distributed system in 5G, where structured data and unstructured data can be stored at central repositories. The Unstructured Data Storage Function (UDSF) will be used as data storage architecture and offers services for data storage, manipulation and retrieval to every Network Function (NF) within the 5G Service-Based Architecture (SBA) (Ahmed et al., 2018). In this paper, the implementation of UDSF has been explained. The UDSF can be used by any NFs to store local data within the centralized repository. The UDSF will be used for achieving a fully stateless AMF (Access and Mobility Function) that achieves higher reliability and load distribution in the network. [ABSTRACT FROM AUTHOR]
