10. 3GPP2 vs. 3GPP Bearers 3GPP2 Bearers (HRPD, UMB) - MMD Rev. B –All bearers are UE initiated –Binding done at the Access Gateway (AGW) –TFTs sent by UE to AGW; AGW validates QoS via Ty with PCRF –AGW does per flow charging 3GPP Bearers (GPRS, UMTS) – Rel. 7 –Both UE and NW initiated bearers supported Binding done at the PCEF for NW initiated bearers Binding done at the PCRF for UE initiated bearers –GGSN sends TFTs to PCRF 3GPP Bearers (EPS) – Rel. 8 –Both UE initiated and Network initiated bearers supported –TS 23.401 has bearer binding in P-GW (none at S-GW) P-GW validates TFTs with PCRF via S7 –TS 23.402 has bearer binding in both the S-GW & P-GW Both S-GW and P-GW validate TFTs with PCRF via S7c/S7 –S-GW does aggregate charging for same QoS bearer, or per flow charging –P-GW does per flow charging

11. Recommendations 3GPP2 AGW-to-PCRF Ty interface evolves to 3GPP S7a 3GPP2 PCRF-to-PCRF Ty interface evolves to 3GPP S9 3GPP2 PCRF-to-AF Tx interface evolves to 3GPP Rx+ S7c and S7a should be closely aligned 3GPP2 access specific information should be added as a cdma2000 access specific annex to Rel. 8 TS 23.203
