Gx Initial Attach and Detach Support
Following are the various types of rules associated with the Gx initial attach and detach support for SMF:
-
PCC Rules: As a part of the initial attach. The PCEF supports:
-
Installation of the dynamic rules using Charging-Rule-Definition AVP
-
Predefined rules using Charging-Rule-Name AVP
-
Bearer binding to the default bearer
NoteThe CBR procedure and UBR for TFT updates on default bearer is not supported in current release.
-
-
Rulebase Selection: PCEF supports the processing of the Charging-Rule-Base-Name AVP. The processing happens as a part of CCA-I and overwrites the ECS rulebase name configuration as part of DNN.
-
APN-AMBR: The APN-AMBR values as a part of Qos-Information AVP by PCRF during the CCA-I/CCA-U/RAR are processed and applied on the call.
-
Default Bearer QoS: The values authorized by PCRF using Default-EPS-Bearer-QoS AVP during the CCA-I/CCA-U/RAR are processed and applied on the call.
