TR 32.819 (SA5)
E-OSF (Element management layer - Operation System Function) definition

|   ToC   |   3GPP‑Page   |   Help   |

V8.0.0 (Wzip)    2008/06    29 p.

Rapporteur:  Mr. Li, Jian

In the Logical Layered Architecture (LLA) of TMN (ITU-T Recommendation M.3010), Network-OSFs (N-OSF) are concerned with the management function on Network Management Level (NML), and Element-OSFs (E-OSF) with the management function on Element Management Level (EML). These two logical layers respectively play the role of Network Management Function (NMF).

This TR identifies and defines the needs in the E-OSFs.

The intention is not to define new requirements for the eventual standardization of new Interface IRP or NRM IRP and/or System Context.

This TR proposes to define the E-OSFs including the following main aspects:
  • Define functional scope of Element-OSF (E-OSF)
  • Define functional requirement of Elements-OSF (E-OSF)
This TR identifies a set of functions require by operators to operate mobile networks. By identifying these functional capabilities and then comparing them with the 3GPP IRP capabilities, widely used functions and omissions in the 3GPP set of IRPs are indicated. Change Requests and new IRPs are expected to be created in order to narrow the functional gap.
