Hello,

Simply speaking, Paging procedure, almost the same procedure with MO.
1. Remove all TCH and SDCCH Blocking
2. Improve the Call Setup SR
3. Check the timer to wait repaging on MSS, if it is too fast try to make longer. This should be calculated inline with number of multiframe between paging, Max retrans
4. Make sure no paging overload

Should i increase the MAX retrance values also as i have already increased the LAC/LAC/GLOBAL TO 7/5/5?

Hi PARSARKA,

Have u tried in your system, LAC SPLIT to increase performance of PAGING...maybe this can be your last option in the future...

Pls add rep if u find it OK and if not, it's ok...badly needed only..TY

Hi,thanks for your suggestions(reputations added ).I have increased the paging timers from 5/5/5 to 7/5/5 & obsreved some improvement.There are no paging discards as network is only 24% loaded.In the network only 2 LACs of remote BSCs are now having poor PSR where the sites are located at an average distance of 2.5kms.Pls suggest what should i do to improve this.

Kevin, if paging load is approx.20%, whether LAC splitting can improve the PSR or not. No of TRXs are 1000 in the LAC? Can split help to increase PSR?

Hi,

Other recomended change is optimize the paramater Rx Level Acces min in Rural BTS or BTS with little overlap.
