+#### 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
+```
