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
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
