[Borjis131]

Following 3GPP TS 29.518 - Release 17.11.0

• MBS Broadcast ContextCreate Service operation [AMF] SBI: MBS Broadcast ContextCreate Service operation #16
• MBS Broadcast ContextRelease Service operation [AMF] SBI: MBS Broadcast ContextRelease Service operation #17

[Borjis131]

To send the MBS Broadcast Context Create request from the AF (for testing purposes, this request should be performed from the MB-SMF), to create a broadcast MBS Context:

# MBS Broadcast Context Create request: /namf-mbs-bc/v1/mbs-contexts
curl --http2-prior-knowledge \
  --request POST \
  --header "Content-Type: multipart/related" \
  --form 'jsonData=<data.json;type=application/json' \
  --form 'binaryDataN2Information=<n2.bin;type=application/vnd.3gpp.ngap;headers="Content-Id: ngap-sm"' \
amf.open5gs.org:80/namf-mbs-bc/v1/mbs-contexts

Needs the JSON file data.json and the binary file n2.bin to work.
