3GPP 29.274 - EPS GTPV2-C interfaces

Rapporteur:  Mr. Landais, Bruno

This TS specifies the stage 3 of the control plane of the GPRS Tunnelling Protocol, Version 2 for Evolved Packet System interfaces (GTPv2-C). GTPv2-C shall be used across:
  • the following EPC signalling interfaces: S2a, S2b, S3, S4, S5, S8, S10, S11 and S16.
  • the Sm and Sn interfaces for MBMS in EPS.
  • Sv (TS 29.280) and S101/S121 (TS 29.276) interfaces.
The procedures supported between the TWAN and the PGW on the S2a interface, and between the ePDG and the PGW on the S2b interface are specified in TS 23.402.
