PoC: Short Message Service Center (SMSC) over SIGTRAN
...As being developed in very limited schedule (bachelor thesis work) it was limited to have very basic functionality: receiving message and deliver it immediately as-is to the receiver. There is no message caching nor different message charset support.
It uses following protocol stack:
MAP (moForwardSM and mtForwardSM)
TCAP (Begin with Invoke + End with ReturnResultLast)
SUA (SCCP User Adaptation): ASP UP/ASP ACTIVE + ACK's and CLDT messages only
SCTP (Linux Kernel - SCTP implementation)
IP
Current implementation is tested in SAMK NGN [http://www.samk.fi/ngn] laboratory's 3G mobile network (real Nokia MSC/VLR network hardware with UTRAN RLC and node-B).
