  1. Comparison of 3GPP2 MMD Ty and 3GPP IMS Gx/S7 Interface Specifications

  2. X.S0013-014-B vs. TS 29.212 v7.3.0 • 3GPP2 Bearer Binding (HRPD, UMB) - MMD Rev. B • All bearers are UE initiated • Binding done at the Access Gateway (AGW) • TFTs sent by UE to AGW and then via Ty to PCRF • AGW does per flow charging • 3GPP Bearer Binding (GPRS, UMTS) – Rel. 7 • Binding done at the GGSN (not at SGSN) • GGSN sends TFTs to PCRF • 3GPP Bearer Binding (EPS) – Rel. 8 • TS 23.401 has bearer binding in P-GW (none at S-GW) • TS 23.402 has bearer binding in both the S-GW & P-GW • S-GW sends TFTs to PCRF via S7 • S-GW does aggregate charging
