v2.5.6 - SCP for Indirect Communication	2022-11-18 22:59:00 +0900	Release	News Release	<style> ul { padding-bottom: 1em; } .blue { color: blue; }</style>

New Feature

SCP(Service Communication Proxy) is added to support Indirect Communication based on TS29.500. The default Open5GS configuration is provided as an indirect communication using SCP.

• [amf.yaml] If NFs are configured to use Delegated Discovery through the SCP, you do not need to set up NRF.

amf:
    sbi:
      - addr: 127.0.0.5
        port: 7777

scp:
    sbi:
      - addr: 127.0.1.10
        port: 7777

#nrf:
#    sbi:
#      - addr:
#          - 127.0.0.10
#          - ::1
#        port: 7777

• [scp.yaml] NRF is needed for Delegated Discovery in SCP configuration.

scp:
    sbi:
      - addr: 127.0.1.10
        port: 7777

#
# next_scp:
#    sbi:
#      addr: 127.0.1.11
#      port: 7777
#

nrf:
    sbi:
      - addr:
          - 127.0.0.10
          - ::1
        port: 7777

• [nrf.yaml] If there is an SCP in the NRF configuration, a notification(nnrf-nfm/nf-status-notify) is sent through an indirect communication.

nrf:
    sbi:
      addr:
        - 127.0.0.10
        - ::1
      port: 7777

scp:
    sbi:
      - addr: 127.0.1.10
        port: 7777
