PoC: Short Message Service Center (SMSC) over SIGTRAN
SIGTRAN based Short Message Center (SMSC) - proof of concept
This is home of my thesis project which had goal of doing open source based Short Message Service Center to be connected into real mobile network (2G, 3G, ...). 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).
