True: If present, and set to true, it indicates that the different service instances of a same NF Service in this NF instance,
supporting a same API version, are capable to persist their resource state in shared storage and therefore these resources
are available after a new NF service instance supporting the same API version is selected by a NF Service Consumer (see 3GPP
23.527 [27]).
False (default): Otherwise, it indicates that the NF Service Instances of a same NF Service are not capable to share resource
state inside the NF Instance.

O
|

|
boolean
|
O
|
0..1
|
This IE indicates whether the NF supports Load Control based on LCI Header (see clause 6.3 of 3GPP TS 29.500 [4]).
True: the NF supports the feature.
False (default): the NF does not support thefeature.
|
olcHSupportInd
|
boolean
|
O
|
0..1
|
This IE indicates whether the NF supports Overload Control based on OCI Header (see clause 6.4 of 3GPP TS 29.500 [4]).
True: the NF supports the feature.
False (default): the NF does not support thefeature.
|
Note
|
At least one of the addressing parameters (FQDN, IPv4address or IPv6adress) is included in the NF Profile. If the NF supports
the NF services with "https" URI scheme (i.e use of TLS is mandatory), then the FQDN provided in the NF Profile or the NF
Service profile (see clause 6.1.6.2.3). See NOTE 1 of Table 6.1.6.2.3-1 for the use of these parameters. If multiple ipv4
addresses and/or ipv6 addresses are included in the NF Profile, the NF Service Consumer of the discovery service must select
one of these addresses randomly, unless operator defined local policy of IP address selection, in order to avoid overload
for a specific ipv4 address and/or ipv6 address.
|
Note
|
If the type of Network Function is UPF, the addressing information is for the UPF N4 interface.
|
Note
|
A requester NF may use this information to select a NF instance (e.g. a NF instance preferably located in the same data center).
|
Note
|
The capacity and priority parameters, if present, are used for NF selection and load balancing. The priority and capacity
attributes must be used for NF selection in the same way that priority and weight are used for server selection as defined
in IETF RFC 2782 [23].
|
Note
|
The NRF must notify NFs subscribed to receiving notifications of changes of the NF profile, if the NF recoveryTime or the
nfStatus is changed. See clause 6.2 of 3GPP 23.527 [27].
|
Note
|
A requester NF may consider that all the resources created in the NF before the NF recovery time have been lost. This may
be used to detect a restart of a NF and to trigger appropriate actions, e.g. release local resources. See clause 6.2 of 3GPP 23.527 [27].
|
Note
|
A NF may register multiple PLMN IDs in its profile within a PLMN comprising multiple PLMN IDs. If so, all the attributes of
the NF Profile must apply to each PLMN ID registered in the plmnList. As an exception, attributes including a PLMN ID, e.g.
IMSI-based SUPI ranges, TAIs and GUAMIs, are specific to one PLMN ID and the NF may register in its profile multiple occurrences
of such attributes for different PLMN IDs (e.g. the UDM may register in its profile SUPI ranges for different PLMN IDs).
|
Note
|
Other NFs are in a different PLMN if they belong to none of the PLMN ID(s) configured for the PLMN of the NRF.
|
Note
|
This is for the use case where an NF (e.g. AMF) supports multiple PLMNs and the slices supported in each PLMN are different.
See clause 9.2.6.2 of 3GPP TS 38.413 [29].
|
Note
|
If notification endpoints are present both in the profile of the NF instance (NFProfile) and in some of its NF Services (NFService)
for a same notification type, the notification endpoint(s) of the NF Services must be used for this notification type.
|
Note
|
The absence of the pcscfInfoList attribute in a P-CSCF profile indicates that the P-CSCF can be selected for any DNN and Access
Type.
|
Note
|
The absence of both the smfInfo and smfInfoList attributes in an SMF profile indicates that the SMF can be selected for any
S-NSSAI, DNN, TAI and access type.
|
Note
|
The servingScope attribute may indicate geographical areas, It may be used e.g. to discover and select NFs in centralized
Data Centers that are expected to serve users located in specific region(s) or province(s). It may also be used to reduce
the large configuration of TAIs in the NF instances.
