What is the reason for the Location Area update failure. Sites have been rehomed to new BSC. All the parameter definations are correct in BSC and sites are in the same BSC as well but there are continues LAC update failures in the region.
There are some cells in location area borders with high failure. when i reduced TA and change the ARFCN , failure reduced but still the failure is around 8000 in whole day. when i again reduced CRO and CRH of 1800 cell then failure increased upto 10000. please suggest what could be the reason for this and how to solve this types of problems.
Hi guys, i have faced an issue of Data Working while mobile in no service mode and post analysis of log a Location Area Update fails Post Authentication failure has been noticed. Suggesting a resolution to this issue would be of great help.
This is happening in vodafone in a specific msc..but during DT lig analysis it has been seen that Loc update fails mostly after authentication failure..which seems to be an authentication failure of TMSI.Plz suggest how far i am correct
