[no] enb-direct-data-forward
[ no ]
Disables direct data forwarding and enables the setup of indirect data forwarding tunnels between the
eNodeB and the RNC via the SGW during SRNS relocation. This allows the S4-SGSN to support connected
mode handovers between the UTRAN and E-UTRAN networks across the S3 interface. This is the default
setting.

enb-direct-data-forward
Enables the use of direct data forwarding between the eNodeB and the RNC via the SGW. If this setting is
configured and the SGSN receives a Relocation Required message from this RNC for a subscriber with target
node as an eNodeB, then the SGSN will set the indication->DFI (direct forwarding indicator) flag in the
Forward Relocation Request message sent across the S3 interface. Use of this command disables the setup of
indirect data forwarding tunnels.
configured and the SGSN receives a Relocation Required message from this RNC for a subscriber with target
node as an eNodeB, then the SGSN will set the indication->DFI (direct forwarding indicator) flag in the
Forward Relocation Request message sent across the S3 interface. Use of this command disables the setup of
indirect data forwarding tunnels.
Usage
Use this command to enable the setup of direct data forwarding tunnels between the eNodeB and the RNC
during inter RAT connected mode handover. Enabling direct data forwarding tunnels allows the S4-SGSN to
support connected mode handovers between the UTRAN and E-UTRAN networks across the S3 interface
without the use of indirect data forwarding tunnels through SGW. Once direct data forwarding is enabled,
indirect data forwarding is automatically disabled.
