SS7 Vulnerabilities—A Survey and Implementation of Machine Learning vs Rule Based Filtering for Detection of SS7 Network Attacks

IEEE Communications Surveys and Tutorials, 2020
The Signalling System No. 7 (SS7) is used in GSM/UMTS telecommunication technologies for signalling and management of communication. It was designed on the concept of private boundary walled technology having mutual trust between few national/multinational operators with no inherent security controls in 1970s.

The standards aspects of SS7 network management

Journal of Network and Systems Management, 1994
Signaling System No7 (SS7) is an internationally standardized general purpose Common Channel Signaling (CCS) system. It is a key component of modern telecommunications networks. Its malfunctioning can cause major problems, as demonstrated in recent history by the spectacular breakdowns induced in public networks by its nonperformance.

Implementation of SS7: Italtel's experience

IEEE Communications Magazine, 1990
Field results in implementing Signaling system No.7 (SS7) in preparation for the introduction of intelligent network (IN) services are reported. Besides implementing SS7 for interexchange trunk signaling, Italtel has adapted it for communications with remote units, i.e. remote switching modules and subscriber multiplexers and concentrators.

Experiences in automating the testing of SS7 signalling transfer points

Software Engineering Notes: an Informal Newsletter of the Special Interest Committee on Software Engineering / ACM, 2002
Signalling System 7 (SS7) is widely used for telephone signalling. Service providers need to frequently test their Signalling Transfer Points (STPs), which switch SS7 messages, for both protocol conformance and interoperability. This paper describes a system that automatically analyzes the data collected during STP tests.

Congestion controls in SS7 signaling networks

IEEE Communications Magazine, 1993
The descriptions of the various congestion-control functions for the common channel signaling system No. 7 (SS7), which are spread widely and piecemeal across the CCITT recommendations, are presented. The protocol architecture of SS7, structured according to Open Systems Interconnection (OSI) principles, is described.

PCS network signaling using SS7

IEEE Personal Communications, 1995
Personal communication services (PCS) facilitates the exchange of information (voice, data, video, image, etc.) for mobile users independent of time, location, and access arrangement. To support PCS, mobile communications protocols such as EIA/TIA Interim Standard 41 (IS-41) or Global System for Mobile Communications (GSM) have been defined for PCS ...

VLSI implementation of the SS7 TCAP

2nd International Conference on ASIC, 2002
The Transaction Capabilities Application Part (TCAP) is the most recent addition to the Signaling System Number 7 (SS7), an open-ended common channel signaling standard that can be used over a variety of digital circuit-switched networks, in particular, ISDN.

Interconnecting SS7 signaling networks

IEEE International Conference on Communications, Including Supercomm Technical Sessions, 1990
The authors discuss signaling system No. 7 (SS7) network interconnection at the network services (message transfer part and signaling connection control part) protocol layers, emphasizing the gateway signal transfer point (STP). Network interconnection is possible on a basis sufficiently open to allow full call- and service-related signaling, while ...

SS7 over IP: signaling interworking vulnerabilities

IEEE Network, 2006
Public telephony - the preferred choice for two-way voice communication over a long time - has enjoyed remarkable popularity for providing acceptable voice quality with negligible connection delays, perhaps due to its circuit-switched heritage. Recently, IP telephony, a packet-based telephone service that runs as an application over the IP protocol ...
