Introduction
The management of the 3GPP network is provided by management services. The service based architecture and
interfaces support various management services of vastly different requirements on network configuration, network
performance, and network fault supervision. The 3GPP network management architecture evolves supporting operators'
design and management of their service oriented networks.

4 Management framework
4.1 Management services
A Management Service (MnS) offers management capabilities. These management capabilities are accessed by
Management Service consumers (MnS consumers) via standardized service interface composed of individually
specified management service components. A MnS is provided by a MnS producer and can be consumed by one or
multiple MnS comsumer(s).

Figure 4.1.1: MnS producer and MnS consumer
4.2 MnS components
4.2.1 Introduction
A MnS is specified using different independent components. A concrete MnS is composed of at least two of these
components. Three different component types are defined, called MnS componenet type A, MnS componenet type B
and MnS componenet type C. These components are defined in the following clauses.
4.2.2 MnS component type A
The MnS component type A is a group of management operations and/or notifications that is agnostic with regard to the
entities managed The operations and notifications as such are hence not involving any information related to the
managed network. These operations and notifications are called generic or network agnostic.
For example, operations for creating, reading, updating and deleting managed object instances, where the managed
object instance to be manipulated is specified only in the signature of the operation, are generic.
4.2.3 Management information
4.2.3.1 MnS component type B
MnS component type B refers to management information represented by information models representing the managed
entities. A MnS component type B is also called Network Resource Model (NRM).
MnS component type B examples are:
1) Network resource models as defined in TS 28.622 [x].
2) Network resource models as defined in TS 28.541 [4].

3GPP TS 28.533 version 15.4.0 Release 15 9 ETSI TS 128 533 V15.4.0 (2020-03)
4.2.3.2 MnS component type C
MnS component type C is performance information of the managed entity and fault information of the managed entity.
The following are examples of Management service component type C:
1. Alarm information as defined in TS 28.532 [9] and TS 28.545 [28].
2. Performance data as defined in TS 28.552 [5], TS 28.554 [6] and TS 32.425 [7].
4.3 Combination of MnS components
A MnS is composed by a MnS component type A and
- a MnS component type B, or
- a MnS component type B and a MnS component type C.
The instances of management services carry information about specified management service components in the
metadata attributes. Figure 4.3.1.illustrates examples of management service instances with various management
service components of type A, type B and type C:

Figure 4.3.1: Example of Management Service and component type A, B and C

4.4 Management capability exposure governance
As precondition for Management Service exposure governance offer, producer of management capability exposure
governance should have access to:
An association between information about specified management service components and instances of management
services.
NOTE: The detail creation of an association is left for implementation and out of scope of 3GPP standardization.

3GPP TS 28.533 version 15.4.0 Release 15 10 ETSI TS 128 533 V15.4.0 (2020-03)
Management capability exposure governance provides exposure governance on basic elements of management function
service based interface:
1) Management service component type A
2) Management service component type B
3) Management service component type C
As described in Figure 4.4.1 left hand part, when there is a Management Service A exposure without exposure
rd
governance, Management Service A Consumer (e.g. 3 party) can access all management capability offered by
Management Service A Producer.
As described in Figure 4.4.1 right hand part, when Management Service A is exposed with applied exposure
governance it becomes Management Service A. Management Service A Consumer can access Management Service A'
after following steps:
- Management Service A, exposed by Management Service A' Producer, is consumed by Management Service A'
Consumer;
- Management Service B, exposed by Management Service B Producer, is consumed by Management Service B
Consumer (e.g. operator) who is authorized to access offered management capabilities exposure governance(s);
- Management Service B Consumer (e.g. operator) request a specified exposure governance on Management
Service A;
- Management Service A Producer produces Management Service A' based on applied exposure governance on
Management Service A.
NOTE: The Management Service A Consumer, the Management Service A' Producer and Management Service B'
Producer can be represented as a single Management Function e.g. a single MnF).

4.5 Management Function (MnF) concept
A Management Function (MnF) is a management entity whose externally-observable behaviour and interfaces are
specified by 3GPP as Management Services.
In the service-based management architecture a MnF plays the role of either Management Service producer or
Management Service consumer. A Management Service produced by MnF may have multiple consumers. The MnF
may consume multiple Management Services from one or multiple Management Service producers. An example of a
MnF playing both roles (Management Service producer and consumer) illustrated in the figure 4.5.1 below.

Figure 4.5.1: Example of Management Function and Management Services
Management Function can be deployed as a separate entity or embedded in Network Function to provide MnS(s).
Following figure 4.5.2 shows an example (on the left) which MnF deployed as a separate entity to provide MnS(s) and
another example (on the right) which MnF is embedded in Network Function to provide MnS(s):

Figure 4.5.1 Examples of MnS deployment scenario
Management Functions may interact by consuming Management Services produced by other Management Functions.
The figure 4.6.2 below illustrates multiple scenarios:
- MnF1 produces Management Service MnS-a;
- MnF2 consumes Management Service MnS-a produced by MnF1 and produces Management Services MnS-b
and MnS-c;
- MnF3 produces Management Service MnS-c;
- MnF4 consumes Management Service MnS-b produced by the MnF2;
- MnF5 consumes Management Services MnS-c produced by the MnF2 and MnF3, and in turn produces the same
Management Service MnS-c. The behaviour of MnF5 may be seen as aggregation of Management Services
MnS-c.

NOTE: The specification of a MnF is out of scope of the present docucument.
4.6 Management data analytics capability
Mobile networks have the capability to support a wide variety of services and requirements. This, along with increasing
flexibility of the network may present management and operational challenges and complexities. The management
system can therefore benefit from management data analytics services for improving networks performance and
efficiency to accommodate and support the diversity of services and requirements. The management data analytics
utilize the network management data collected from the network (including e.g. service, slicing and/or network
functions related data) and make the corresponding analytics based on the collected information. For example, the
information provided by PM data analytics services can be used to optimize network performance, and the information
provided by FM data analytics services can be used to predict and prevent failures of the network. MDAS can be
deployed at different levels, for example, at a domain level (e.g., RAN, CN, NSSI) and/or in a centralized manner (e.g.,
at a PLMN level).

4.7 Management service discovery
4.7.1 Introduction
The MnS consumer in an operator’s management system need to discover the availability of MnS instances provided by
other MnS provider(s). In order to enable the MnS instances to be discovered by MnS consumer, the MnS needs to be
discoverable to the operator’s management system when the MnS instance become operative.
4.7.2 MnS data
The MnS data includes the information of MnS instance used for MnS discovery.
4.7.3 MnS discovery service
The MnS discovery service enables MnS consumer to discover management capabilities of MnS instances provided by
MnS provider(s). The MnS consumer sends a MnS query request to MnS discover service provider to discover MnS
instances and receives response with the MnS data of MnS instances which satisfy the request.
The MnS discovery service is illustrated in Table 4.7.3-1.
