Hi all..
What i already explain was a HLRENQ routing, and i believe you already now about that. Usually we will define MSISDN not with complete/full range for example if the SN(sub. number) is a 3409339 and your NDC for example 13, we will define 13340 in tree 2 and destinations is to HLR… but before that, it should be start from pre-analysis, MSISDN and IMSI define (the command base on your software release, in nokia every software release the command will change-some not all.. )
