provides signaling using SCTP associations over the Internet Protocol. The protocols for
are M2PA, M2UA, M3UA and SUA.
Signaling Gateway is a network component that performs packet level translation of signaling from common channel signaling (based upon SS7) to
signaling (based upon IP). The concept of the
signaling gateway was introduced in the IETF document: RFC 2719: Architectural Framework for Signaling Transport.
RFC 2719: Architectural Framework for Signaling Transport.
is the name, derived from "signaling transport", of the former Internet Engineering Task Force (IETF) working group that produced specifications for a family of protocols that provide reliable datagram service and user layer adaptations for Signaling System 7 (SS7) and ISDN communications protocols. The
protocols are an extension of the SS7 protocol family. It supports the same application and call management paradigms as SS7 but uses an Internet Protocol (IP) transport called Stream Control Transmission Protocol (SCTP), instead of TCP or UDP. Indeed, the most significant protocol defined by the
group is SCTP, which is used to carry PSTN signaling over IP.
Access to the signalling link functional level's service interface can be provided over SCTP by the
protocol M2UA, described in RFC 3331.
Access to the signalling network functional level's service interface (as described in Q.701) can be provided over SCTP by the
protocol M3UA, described in RFC 4666.
The Internet Engineering Task Force (IETF) has defined the
protocol suite that implements levels 2, 3, and 4 protocols compatible with SS7. Sometimes also called "Pseudo SS7",
The Internet Engineering Task Force (IETF) defined
protocols which translate the common channel signaling paradigm to the IP Message Transfer Part (MTP) level 2 (M2UA and M2PA), Message Transfer Part (MTP) level 3 (M3UA) and Signalling Connection Control Part (SCCP) (SUA). While running on a transport based upon IP, the
protocols are not an SS7 variant, but simply transport existing national and international variants of SS7.
has been published in RFC 2719, under the title "Framework Architecture for Signaling Transport". RFC 2719 also defines the concept of a "signaling gateway" (SG), which converts Common Channel Signaling (CCS) messages from SS7 to
. Implemented in a variety of network elements including softswitches, the SG function can provide significant value to existing common channel signaling networks, leveraging investments associated with SS7 and delivering the cost/performance values associated with IP transport.
The July 2010 acquisition of Mutina Technology S.p.A. expanded the company’s offerings to cover Mobile Broadband (MBB), Next Generation Networks (NGN), SS7/
Signaling, VoD/IPTV, and IP Core for telecom and enterprise networks.
The IETF Signaling Transport (
) working group defined the protocol (number 132)in 2000, and the IETF Transport Area (TSVWG) working group maintains it. RFC 4960 defines the protocol. RFC 3286 provides an introduction.
MAP is a Transaction Capabilities Application Part (TCAP) user, and as such can be transported using 'traditional' SS7 protocols or over IP using "Transport Independent Signalling Connection Control Part (TI-SCCP)"; or using
While the MAP 3GPP specifications make some effort to divorce MAP from the layer that transports it, the typical transport is via TCAP which in turn is via SCCP/MTP[1-3] and/or
protocols (SUA, M3UA etc.).
Q.2210 describe the signalling link function referred to as "MTP3b". The signalling link functional level may also be provided using the
protocol M2PA described in RFC 4165.
The Stream Control Transmission Protocol provides the transport protocol for
user adaptation layer messages across an IP network. It is described in RFC 3873, RFC 4166 and RFC 4960.
Note here that Analogue (ATA), PSTN telephone devices can only be reached by a softswitch that has embedded SS7 or
cards, software in terms of signalling AND Trunking Gateway for Voice traffic IP/TDM, TDM/IP, TDM/TDM functions.
Applications served by probes include solutions for inter-carrier billing, revenue loss (by-pass/phantom traffic and analysis services), fraud prevention, billing, local number portability, quality of service, surveillance (global call trace), maintenance (protocol analysis), traffic engineering (link and trunk forecasting), alarming and SS7,
and IS-41 monitoring.
M3UA stands for MTP Level 3 (MTP3) User Adaptation Layer as defined by the IETF
working group in (which replaces and supersedes ). M3UA enables the SS7 protocol's User Parts (e.g. ISUP, SCCP and TUP) to run over IP instead of telephony equipment like ISDN and PSTN. It is recommended to use the services of SCTP to transmit M3UA.
While any signaling gateway is usually on the same physical switch as a media gateway, there is no such need. The Call Agent does not use MGCP to control the Signaling Gateway; rather,
protocols are used to backhaul signaling between the Signaling Gateway and Call Agent.
The designers of SCTP originally intended it for the transport of telephony (Signaling System 7) over Internet Protocol, with the goal of duplicating some of the reliability attributes of the SS7 signaling network in IP. This IETF effort is known as
. In the meantime, other uses have been proposed, for example, the Diameter protocol and Reliable server pooling (RSerPool).
