To Huawei 3G Expert,

In my network below counter were pegging too much:

VS.RRC.Paging1.Loss.PCHCong.Cell

Based on the Counter definition mean… Number of Paging Messages Lost due to PCH Congestion, Cell.

I would like to know what is the parameter on Huawei 3G that can increase the PCH capacity to reduce this paging failure.

Appreciate if anyone can suggest.
Thanks

Consider disabling CELL PCH state on that cell.

After CELL PCH state disable mobiles will not receive data in DL on CELL PCH channel, just on CELL FACH and DCH.

I think you need to config the 2 channel FACH, and check the State transaction feature or fast dormancy.

You can try to redesign the LAC and RAC.
For me, i had PCH congestion and i had separated the RAC of one LAC into to RAC.

Yes, LAC splitting will also help.

Enable layer paging and do lac splits.
