7.1 TM architectural aspects

32.1013GPPPrinciples and high level requirementsRelease 17Telecommunication managementTS

The basic aspects of a TM architecture, which can be, considered when planning and designing a TM are:

– the functional architecture;

– the information architecture;

– the physical architecture.

The management requirements from the business needs are the base for the functional architecture, which describe the functions that have to be achieved. The information architecture defines what information that has to be provided so the functions defined in the functional architecture can be achieved. The physical architecture has to meet both the functional architecture and the information architectures. These relationships are shown in figure 5.

The present document addresses the functional architecture. The physical architecture is addressed in TS 32.102 [101].

Figure 4: Architectural relationship

All management processes have functions in several management areas. By identifying only those processes and interfaces relating to a certain management function, for example performance management, it is possible to take a slice through the Enhanced Telecom Operations Map that details the functional architecture for performance management, this will be the approach taken by the present document.

The management functions are:

– Performance management;

– Roaming management;

– Fraud management;

– Fault management;

– Security management;

– Software management

– Configuration management;

– Accounting management;

– Subscription management;

– Quality of Service (QoS) management (see informative annex D);

– User equipment management.

The 3GPP IRP methodology focuses on providing the definitions for the O&M operations and notifications needed to support the business requirements provided by the eTOM framework for such management functions.
