Activate RRC Redirection affected to CSSR?

[Budaxbaix]

Dear All,

In our Network, there are several NodeB have high IuB Congestion. IuB Upgrade can not be done immediatelly.
We already set TRM factor to 30% but the CSSR still low, and plan to load sharing with 2G with RRC redirection.

/*Activating Service Steering and Load Sharing in RRC Connection Setup*/

/*Enabling the RRC DRD function*/
SET UCORRMALGOSWITCH: DrSwitch=DR_RRC_DRD_SWITCH-1;

//Setting the RNC-level DRD switch
SET UREDIRECTION: TrafficType=AMR, RedirSwitch=ONLY_TO_INTER_RAT,
RedirFactorOfNorm=0, RedirFactorOfLDR=0, RedirBandInd=BAND1,
ReDirUARFCNUplinkInd=FALSE, ReDirUARFCNDownlink=10713;

//Setting the cell-level DRD switch
MOD UCELLREDIRECTION: CellId=1, TrafficType=AMR,
RedirSwitch=ONLY_TO_INTER_RAT, RedirFactorOfNorm=0,
RedirFactorOfLDR=100, RedirBandInd=BAND1, ReDirUARFCNUplinkInd=FALSE,
ReDirUARFCNDownlink=10563;

RRC Redirection:
The initial signaling connection is established, the cell request is rejected, and the RRC directed retry fails. (Directed retry has a higher priority than redirection. When the directed retry fails, redirection is triggered after the cell request is rejected.)

As I know for RRC DRD, RRC fails are not counted if RRC is successfully directed to another cell.

How about RRC Redirection, after cell request is rejected then if it successfully redirection to GSM Cell whether still counted as RRC fail?

Because I only found the counter RRC Reject Redirection, no Attempt of Success
VS.RRC.Rej.Redir.Service
VS.RRC.Rej.Redir.InterRat
VS.RRC.Rej.Redir.IntraRat

Thanks

It seem RRC Redirection will count as RRC fail, but the advantage is after the user redirection to GSM and success then there is no RRC attempt in that cell from same user in a period time. It will reduce number of RRC fail due to always retry to access on that cell.
