When the senders SMSC contacts HLR, can we not configure HLR in such a way that for the shared number, HLR returns the SMSC as the destination MSC. Of course, SMSC needs to understand MAP_MT_ForwardShortMessage and convert to SMPP ad finally deliver it to ESME.
This puts a requirement that SMSC shall understand both MAP_MO_ForwardShortMessage as well
MAP_MT_ForwardShortMessage. Is my understanding correct?
An SMSC would only support inbound MO by default.. it would have to have the MT termination functionality built in to receive the MT.. and thats not normally the case.
Do SMSCs receive on SMSs on SMPP interface and send out too SMPP towards a ESME (in this exampe)? Do typical GSM-SMSCs and CDMA-SMSCs support this functionality?
Oh yes.. SMPP is heavily used (as are other protocols) to route messages in and out of SMSCs.. mostly for attached services, such as voice mail alerts, services, IM gateways etc. SMSCs are never exclusively MO/MT.
