scope:
The present document specifies the stage 3 of the Evolved Packet System S101 interface between the MME and the HRPD Access Network. The S101 interface supports procedures for Pre-Registration, Session Maintenance and Active handoffs between E-UTRAN and HRPD networks.
It also specifies the S103 interface between the Serving GW and HRPD PDSN. This User Plane interface is used to forward DL data to minimize packet losses in mobility from E-UTRAN to HRPD. Signalling procedures on the S101 interface are used to set up tunnels on the S103 interface.
