3gpp-Sbi-Discovery Header

If you have configured the Model D, the SMF doesn't trigger the NF discovery and sends the message with the discovery parameters to SCP for the peer selection.

By default, SUPI and target NF type are added. SMF includes the 3gpp-Sbi-Discovery HTTP header for each query parameter that is configured in the network element profile in following format:

3gpp-Sbi-Discovery-<query-param>

Following are the examples of the 3gpp-Sbi-Discovery header:

3gpp-Sbi-Discovery-dnn: internet
3gpp-Sbi-Discovery-snssais: [{"sst": 1, "sd": "A08923"}, {"sst": 1, "sd": "0023F1"}]
Note
  • Both 3gpp-Sbi-Discovery-target-plmn and 3gpp-Sbi-Discovery-source-plmn are always included for the inter-PLMN discovery. However, these parameters aren't supported.

  • The 3gpp-Sbi-Discovery-supi header must be added to all the messages.
