Configuring SRB over HSUPA

This section describes how to activate, verify, and deactivate the optional feature WRFD-010636 SRB overHSUPA.

Prerequisites

Dependencies on Hardware

BSC6900

This feature does not depend on the hardware.

Requirements for the NodeB

The BTS3812E, BTS3812A, or BTS3812AE is configured with the EBBI,EBOI, or EDLP board.

The BBU3806 is configured with the EBBC or EBBCd board. TheBBU3806C is configured with the EBBM board.

The BBU3900 is configured with the WBBPb or WBBPd board.

Dependencies on Other Features

The WRFD-010612 HSUPA Introduction Package feature must be configured beforethis feature is configured.

License

The license controlling this feature has been activated.

Other Prerequisites

The transmission mapping to support SRB over HSUPA has been configured.

Context

This feature provides high signaling rate and shortens call setup delay. Compared with the function ofcarrying SRBs on DCHs, this feature saves code resources and reduces cell load.

Procedure

Activation Procedure

1. Run the BSC6900 MML command SET UFRCCHLTYPEPARA to set Type ofChannel Preferably Carrying Signaling RB to HSUPA(UL_EDCH,DL_DCH) orHSPA(UL_EDCH,DL_HSDSCH).

NOTE:

If the feature is effective in the case of RRC connection establishment, set EffectiveFlag of Signaling RB Channel Type to TRUE.

Verification Procedure

1. Run the BSC6900 MML command LST UFRCCHLTYPEPARA to query whether theSRBs are carried over HSUPA.

2. Use a UE with the HSPA function to set up an RRC connection on the enhancedDCH (E-DCH).

View the RRC_RRC_CONN_SETUP message from the Uu interface trace data. If theEDCH information is contained in the message, this feature is activated.

Deactivation Procedure

1. Run the BSC6900 MML command SET UFRCCHLTYPEPARA to set Type ofChannel Preferably Carrying Signaling RB to DCH(UL_DCH,DL_DCH) andEffective Flag of Signaling RB Channel Type to FALSE.

Example

//Activating SRB over HSUPASET UFRCCHLTYPEPARA: SrbChlType=HSUPA, SrbChlTypeRrcEffectFlag=TRUE;

//Verifying SRB over HSUPALST UFRCCHLTYPEPARA:;

//Deactivating SRB over HSUPASET UFRCCHLTYPEPARA: SrbChlType=DCH, SrbChlTypeRrcEffectFlag=FALSE;
