C.4.4 Reference points p. 59
C.4.4.1 Offline charging reference points p. 59
C.4.4.1.1 Gz p. 59
When applied to PCEF located in IP-Edge, the Gz reference point functionality relies on Rf or Ga Reference Points within the common charging architecture.
C.4.4.1.2 Gzn p. 59
The TDF when used for application based charging in a convergent scenario performs the same functionality as outlined in this document and in addition the Gzn reference point enables transport of offline charging information for both Non-seamless WLAN offloaded traffic from a 3GPP UE and for fixed devices.
C.4.4.2 Online charging reference points p. 59
C.4.4.2.1 Gy p. 59
When applied to PCEF located in IP-Edge, the Gy reference point functionality relies on Ro Reference Point within the common charging architecture.
C.4.4.2.2 Gyn p. 59
The TDF when used for application based charging in a convergent scenario performs the same functionality as outlined in this document and in addition the Gyn reference point allows online credit control for TDF based charging for both Non-seamless WLAN offloaded traffic from a 3GPP UE and for fixed devices.
