Configuring Downlink Enhanced CELL_FACH
This section describes how to activate, verify, and deactivate the optional feature WRFD-010688 DownlinkEnhanced CELL_FACH.
Prerequisites
Dependencies on Hardware
This feature does not have any special requirements for hardware.
Dependencies on Other Features
The configurations of the features on which this feature depends are complete. Thisfeature depends on the feature WRFD-010685 Downlink Enhanced L2.
License
The license controlling this feature has been activated.
Other Prerequisites
The UE should support this feature.
HBBI and HDLP on BTS3812E/BTS3812AE do not support this feature, EBBI, EDLPis needed.
BBU3806 does not support this feature, EBBC or EBBCd is needed. EBBM isneeded by BBU3806C to support this feature.
3900 series NodeB: WBBPa does not support this feature, and WBBPb or WBBPd isneeded.
Context
This feature enables the FACH to be carried on the HS-DSCH. Based on this feature, the UE can receivedata at a higher rate in CELL_FACH state.
Procedure
Activation Procedure
1. Run the BSC6900 MML command MOD UCELLALGOSWITCH to select E_FACHand DL_L2ENHANCED from the drop-down list Cell Hspa Plus function switch.
2. Run the BSC6900 MML command ADD UCELLHSDPA to add HUDPA parametersof a cell.
3. Run the BSC6900 MML command ADD UCELLEFACH to add enhancedCELL_FACH state parameters of a cell.
4. Run the BSC6900 MML command ACT UCELLHSDPA to activate HSDPA feature.
5. Run the BSC6900 MML command ACT UCELLEFACH to activate this feature.
