9 TMN applications p. 31
Telecom management applications can be implemented in many different ways depending on constraints presented in previous clauses. The TMN application - the operations systems component (OSC) -is the physical realization of one or more OSFs needed to support the operational processes. An up-to-date Operations System would be assembled from one or more OS components which expose standardized interfaces to allow for more flexible and agile OSs.
To identify and specify the design criteria that will allow re-usable application components to be developed across multiple telecom business scenarios are important issues to fulfil the basic 3GPP Management requirement. "To minimise the costs of managing a PLMN such that it is a small component of the overall operating cost".
The implication of the top down approach in the standardising work of 3G is that consistent operational management processes are required irrespective of vendor equipment.
Generic and re-usable management applications are required to facilitate:
- Reduced management application development costs.
- Simplification of operational processes and associated reduction in costs.
- Reduced time to deploy new services as management systems already exist.
- Consistent representation of basic information.The complexity and heterogeneous nature of a 3GPP system calls for easy integration (plug&play) of HW/SW.
9.1 Management function blocks p. 31
A management function is the smallest part of a business process (or management service), as perceived by the user of the process (or service). A management function block is the smallest deployable unit of management functionality. Figure 9.1 illustrates the different types of optional management function blocks. For example physical views and mapping to 3GPP PLMN management interfaces, see subclause 9.2 and subclause 9.3. The OSF specializations/decompositions reflect the high level processes identified in ITU-T TMN Enhanced Telecom Operations Map(eTOM), M.3050.x series, ref[20]., See further M.3060/Y.2401 ref [16].

9.2 Management physical blocks p. 32
Figure 9.2-1 illustrates example implementations of physical views. The OS physical block realizes OSFs, of which a great variety is available. Some will be consequence of 3GPPs decision to base the management processes on Enhanced Telecom Operations Map [2],[9],[20], others on enabling support for the management of Next Generation Networks [16], [17].

The physical architecture may flatten the functional Management Layers into a single, unified management layer for the co-management of several functional Management Layers to facilitate a unified handling of e.g. alarms and performance data. There is great flexibility in the design of Next Generation Network Operations Systems with this concept, see further Annex 1. The flexibility can enable co-management of multiple functional layers as presented in Figure 9.2-2. The interfaces depicted in Figure 9.2-1 and Figure 9.2-2 are in the 3GPP PLMN management architecture mapped to the Itf-N or Itf-P2P interface between an IRPManager and IRPAagent, as shown in Figure 9.3.

9.3 IRP concept enabling TMN applications p. 33
3GPP has developed the interface concept "Integration Reference Point" (IRP) to promote the wider adoption of standardized management interfaces in telecommunication networks. The concept is presented in TS32.150 [5]. These IRPs are provided by an IRPAgent and managed via an IRPManager. The IRPs are the prime enabler of flexibility in the design of management physical blocks (OSs).
In the context of management of Next Generation Networks the IRPAgent and IRPManager represents the provider reference point and respectively the consumer reference point, respectively. See Figure 9.3.
The IRP concept may be mapped to all of the management physical blocks. The 3GPP PLMN Management Architecture will focus on those functions, methods and interfaces that the new challenges of 3GPP Telecom Management may require. The detailed and final standardization requirements will be targeted in other 32.*** series and 28.*** series of standards.
