Send Routing Info for SM to another operator

Several days ago, someone ask me about “What message should I put when my system send SRI (Send Routing Information) to another PLMN ?”

Teoritically I know the answer, but I have to prove it practically.

If you create the SMSC and you want to send SRI to another operator your newtwork configuration should like this

SMSC_A — MSCGW_A ——- MSCGW_B — HLR_B

You don’t have to know MSCGW_B’s and HLR_B’s GT, you just have to know your MSCGW (MSCGW_A)’s GT

After I do tap on my SMSC, I’ve got the MSU information

On SCCP PDU

Calling Party side
CgPA = SMSC’s GT
SSN  = 8
RI = Route on GT

Called Party side
CdPa = MSCGW_A’s GT
SSN  = 8
RI = Route on GT

You can put your SPC & DPC information also, but I think it will be discarded because you have define the RI

Hi, where’s the A number ?
You can put your A# information on MSISDN field on MAP_SRI PDU

It’s easy, but we have to prove it 🙂
