The SCCP User Adaptation (SUA), a part of SIGTRAN protocol
solution set, defines the transport of SCCP-user messages
(MAP & CAP over TCAP, RANAP, etc.) and new third
generation network protocol messages over IP between
two signaling endpoints using the Stream Control Transport
Protocol (SCTP).
SUA provisions a seamless, or as seamless as possible,
operation of the SCCP User Protocol peers in the SS7
and IP domains. In simplistic transport terms, SG will
terminate SS7 SCCP protocol layer and deliver TCAP or
any other SCCP User protocol messages over SCTP transport
associations to SCCP-user peers on MGC. This protocol
is also used between any two signaling endpoints wholly
contained within an IP network.
Following are the architectures in which SUA is deployed:
- All IP Architecture
- Signaling Gateway Architecture
