In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an agency
the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document

3GPP TS 28.202 version 16.1.0 Release 16 10 ETSI TS 128 202 V16.1.0 (2021-01)
The Charging Enablement Function (CEF) is defined in TS 28.201 [70]: charging information addressed by the CEF in
the present document, are related to provisioning for network slices.
The MnS producer is defined in TS 28.533 [250]: the MnS producer in the present document is the producer of
provisioning MnS.
For network slice management converged charging the CEF is a consumer of both:
- provisioning service (MnS) for network slice exposed by the MnS Producer, specified in TS 28.532 [253];
- charging (Nchf) service.
Details on the interfaces and functions can be found in TS 32.240 [1] for the general architecture components. Ga is
described in clause 5.2.4 and Bns in clause 5.2.5 of the present document, and Nchf is described in TS 32.290 [50].
5 Network Slice Management charging principles and
scenarios
5.1 Network Slice Management charging principles
5.1.1 General
The charging functions for the Network Slice Management charging, are based on provisioning management services
used for provisioning of network slice.
The management services are specified under TS 28.533 [250], TS 28.532 [253] and TS 28.541 [254]. Management
services and procedures for provisioning are described TS 28.531 [252].
How a MnS consumer consumes and is authorized to consume provisioning MnS produced by the MnS producer, are
out of the scope of the present document.
The network slice subscriber is the tenant, i.e. the party for which the network slice instance(s) is(are) created,
satisfying the requirements of subscribed-to service(s).
NOTE 1: these service(s) requirements may take the form of Service Level Specification (SLS) per TS 28.530 [251]
definition, supplied by external service providers (e.g. MVNO, Verticals, enterprises), in which case the
tenant is the external service provider.
NOTE 2: these service(s) requirements may be built by a MNO for its own operational needs, in which case the
tenant is the MNO itself, and the tenant id may not be present.
Depending on the relationship and deployment model between the tenant and the party owning the MnS producer, the
MnS consumer of the provisioning MnS may be the tenant.
The following provisioning of network slice procedures of clause 7 in TS 28.531 [252] are considered for Network
Slice Management charging:
- Network Slice Instance (NSI) Creation.
- Network Slice Instance (NSI) Modification.
- Network Slice Instance (NSI) Termination.
Network Slice Instance (NSI) is defined in TS 28.530 [251].
5.1.2 Requirements
The following are high-level charging requirements specific to the Network Slice Management charging:
- The CEF shall support converged charging.

3GPP TS 28.202 version 16.1.0 Release 16 11 ETSI TS 128 202 V16.1.0 (2021-01)
- The CEF shall collect charging information per NSI Creation, Modification and Termination.
- The Service Producer (CTF) shall support converged charging.
- The Service Producer (CTF) shall collect charging information per NSI Creation, Modification and Termination.
5.1.3 Network Slice Management charging information
The charging information for Network Slice Management charging are defined under the following list:
- identity of the MnS consumer of provisioning MnS.
- identity of the tenant, i.e. viewed as the network slice subscriber.
- operation type invoked by MnS consumer of provisioning MnS.
- identifier of the Network Slice Instance.
- network slice related requirements identified by a service profile as defined in TS 28.531 [252] clause 4.5. and
detailed in TS 28.541 [254] clause 6.3.3.
The following non-exhaustive list of information elements of the service profile are identified for Network Slice
Management charging:

5.1.4 CHF selection
The CHF selection by the MnS Producer (CTF)/CEF is based on the following options and with this priority order
(highest to lowest):
- NRF based discovery;
- pre-configured CHF address(s).
5.2 Network Slice Management charging scenarios
5.2.1 Basic principles
5.2.1.1 General
Network Slice Management charging is performed by the Service Producer (CTF) of provisioning MnS or the CEF
interacting with CHF using Nchf specified in TS 32.290 [50] and TS 32.291 [51]. In order to provide the data required
for the charging management activities outlined in TS 32.240 [1], the Service Producer (CTF) or CEF shall be able to
perform converged charging for provisioning MnS when consumed by MnS consumer for NSI allocation, modification
and deallocation.
The Service Producer (CTF) of provisioning MnS or CEF shall be able to perform converged charging by interacting
with CHF, for charging data related to Network Slice Management. The Charging Data Request and Charging Data
Response are exchanged between the Service Producer (CTF) and the CHF or between the CEF and the CHF, based on
PEC scenarios specified in TS 32.290 [50]. The Charging Data Request is issued by the Service Producer (CTF) or CEF
towards the CHF when certain conditions (chargeable events) are met.
The CEF shall be able to consume services related to provisioning MnS events, defined in TS 28.531 [252], for
collecting charging information related to Network Slice Management.
The contents and purpose of each charging event that triggers interaction with CHF, as well as the chargeable events
that trigger them, are described in clauses 5.2.2.
A detailed formal description of the converged charging parameters to CHF defined in the present document can be
found in TS 32.291 [51].
A detailed formal description of the CDR parameters defined in the present document can be found in TS 32.298 [57].
Whether network slice management charging is active is configured in MnS producer or CEF.
5.2.1.2 Applicable triggers in Network Slice Management charging
A set of trigger conditions are defined for the CEF or Service Producer (CTF) to invoke a Charging Data Request
[Event] towards the CHF.
Table 5.2.1.2.1 summarizes the set of default trigger conditions and their category which shall be supported by the CEF
or Service Producer (CTF).
