Hi all,i have simple question.
Lets assume: in one region it was implemented new frequency plan. In result on one particular cell appears hight traffic from LU.LACs are the same.What will be the reason?
Thank you

hi JE,

it’s probably one or few faulty MS which are going crazy. the only way to investigate this is to trace the A interface and correlate the IMSI or IMEI with the phone brand/model.

improbable causes:
– too short value for T3212
– bad LAC design : check that the neighbours do have the same LAC indeed
– MS attaching to your network because their own network is down (collocated BTS from another operator is down, for example)
