Cell protection algorithm causes RRC rejection due to unknown reason.
Huawei throuble shooting case of Cell protection algorithm causes RRC rejection due to unknown reason.
Phenomenon Description:
RNC version is: BSC6800 V100R08C01B082SP05
For the whole week 09.02.2009 -15.02.2009, the sum of VS.RRC.Rej.Power.Cong+VS.RRC.Rej.Code.Cong+VS.RRC.Rej.DL.CE.Cong+VS.RRC.Rej.UL.CE.Cong=0. (See the first sheet in the attachment) Furthermore no IUB congestion has appeared based on the value of VS.IUB.CongDL, VS.IUB.CongUL, VS.IUB.TimeCongDL and VS.IUB.TimeCongUL
Suggestions and Summary:
If the value of RRC.FailConnEstab.Cong is too big without any reason, refer to the described explanation.

Hi jukreew,
Please add below counter also: VS.RRC.Rej.NodeBResUnavail This counter will show rejections when DCH Users(VS.DCHUEs) exceed 100.
The maximum system capacity is 128 for DCH users.
