Implementing SCCP Relay for MAP Send-Route-Info-For-SM in case Mobile Number Portability

  • Hi All,

    I am now develop and maintaining HLR modules that utilizing MAP stack as desribed in dialogic MAP programming manual. My module does handle update location, cancel location, any time interogation without problems. But now we got this urgent issue when we are required to forward MAP-send-route-info-for-SM from remote GMSC, as the number is subject to number portability(ported out), we have to forward it to external HLR. As TS 23.066, this is how it should be achieved:

    We act as MNP SRFB'.

    Now my question is, how to just forward the incoming SRI-SM to remote party, maintaining that MAP invoke-id is same, TCAP transaction-id is same, or in general, that the forwarding covers both SCCP layer and TCAP layer. As previously, what we done is just create other new MAP dialog and send it to remote HLR, but this requires the remote HLR reply back to us, while actually the HLR sends directly to original sender as requirements above. Is it possible to achieve this only using MAP stack interface ? or do we have to do specific SCCP relay as mentioned in TS 23.066(i am not sure about what it this)? please advice. thank you

  • any advice?
