If you want to use 5G with HTTP/2 agents, you require a 5G profile configuration. You can select the profile that you configure in the HTTP/2 Server agent configuration.

In the 5G profile configuration, enter the details required to register an NF (Network Function) instance in the NRF (NF Repository Function).

Configuration

The 5G profile consists of the following tabs:

General Tab

5G Profile - General tab

Setting	Description
3GPP Version Setting
Version Select	Select the version of 3GPP to apply to the 5G Profile. Note! 3GPP Release 15 is the current default version supported by . Release 16 was added to support the handling of 3xx status codes.
Enable Custom Specification	Support the custom version of the specification of NRF NFManagement Service. See Custom Specification Enabled for more information. Info! When enabling custom specification, all fields except for OpenAPI Profile and Enable Validation will be disabled. You need to use the Analysis agent or APL Code to create the `NRFspecificationUDR` that will contain all the values for the disabled fields. See Custom Specification Enabled for more information.
OpenAPI Profile	Select the OpenAPI profile for specification of NRF NFManagement Service.
Enable Validation	Validate the request for NF (Network Function) registration, heartbeat and de-registration against the OpenAPI schema provided from the OpenAPI profile.
Configure Server Settings
Path	Enter the exact path to where the HTTP request will register, de-register and update the NF profile in the NRF. Example: /nnrf-nfm/v1/nf-instances/
*Configure NF Settings*
NF Instance name	Enter the name of the NF instance for the NF type that you want to use.
NF type	A list of various NF types is available for selection. The default is set to CHF (charging function).
Heartbeat timer	Enter how often you want the NF registration to be updated in seconds in the NRF.
NF Registration status	Select the registration status that you want to have updated. You can select REGISTERED or UNDISCOVERABLE. Select REGISTERED to register your NF instance to the NRF. Select UNDISCOVERABLE if you want to register to the NRF but without being discovered by other NFs.
FQDN	Enter the Fully Qualified Domain Name (FQDN) for the NF instance.
Support NRF Change	Select this option to allow the NRF server to modify the heartbeat timer provided by the NRF client upon registration.
IPv4 Address List	You can add the IPv4 address(es) for the NF instance.
IPv6 Address List	You can add the IPv6 address(es) for the NF instance.

Note!

You must enter at least an FQDN, an IPv4 address or an IPv6 address, but you are not required to make an entry for all of these fields. In addition, you can enter any combination of the three fields that you require.

Advanced Parameters Tab

5G Profile - Advanced parameters tab

In this tab, you can add settings in a JSON configuration in accordance with 6.2.6.2.3 "Type: NFProfile" as defined in 3 the specification GPP TS 29.510, https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3345. See the example below:

Note!

Values set in the Advanced Parameters tab will override those set in the General tab.

Example - Json configuration of advanced parameter

	"nfProfileChangesSupportInd": true,
	"nfProfileChangesInd": true,
	"allowedPlmns": [

                           }

	]
}

Custom Specification Enabled

When custom specification is enabled in 5G Profile, HTTP/2 Server agent will not perform registration of NF (Network Function) automatically during the startup of the workflow. The HTTP/2 Server agent will instead, wait to receive the NRFspecificationUDR in order to perform NF registration, heartbeat and de-registration. You can refer to the example below:

An example workflow of HTTP/2 Server Agent with 5G Profile enabled and an Analysis Agent

Example - HTTP/2 Server agent with 5G custom enabled

The example workflow consists of HTTP/2 Server Agent with 5G Profile enabled and Analysis Agent to construct the NRFSpecificationUDR. When the workflow starts, the HTTP/2 Server Agent will route the NRFSpecificationUDR to the Analysis agent to construct the NRFSpecificationUDR as shown below. The constructed UDR is then routed back to the HTTP/2 Server Agent in order to perform the NF (Network Function) registration, heartbeat and de-registration.
