CSMF

Communication Service Management Function

Management plane function translating enterprise business requirements into 3GPP network slice requirements.

Technical Explanation

The CSMF operates in the operator's OSS/BSS layer. It exposes high-level service ordering APIs to enterprise clients. When an enterprise requests a private network with 10 Gbps throughput and 5 ms latency, the CSMF translates these requirements into standardized Generic Slice Templates (GST) for the NSMF.

Key Functions

  • Translates customer business requirements into technical slice parameters
  • Exposes slice ordering portals to corporate and vertical enterprise clients
  • Generates standardized Generic Slice Templates (GST) for slice provisioning
