Simulation of SS7 common channel signaling

IEEE Communications Magazine, 1994
Simulating trunk and signaling networks allows planners to examine network survivability, capacity, and the impact of new service introductions. The challenge is to accurately predict network performance and behavior for a rapidly changing environment, and for the very large networks that are encountered in the public telephone system.

SS7 network management using link monitors

Proceedings of ICC'97 - International Conference on Communications, 2002
The disruption and loss of SS7 signalling networks during the summer of 1991 in North America by the "brown outs" and the resultant loss of services, revenue and customers, has focused the minds of many Telcos to put management systems in place to ensure network robustness.

Evolving network services applications of SS7 signaling

Fourth IEEE Region 10 International Conference TENCON, 2003
The increasing emphasis on corporate networks is resulting in a distribution of communications intelligence from the traditional central office to customer premises. This calls for Signaling System No.7 (SS7) or equivalent signaling in the interexchange carriers and regional Bell operating companies (RBOC) networks as the backbone, and the use of ...

SS7 over IP - Signalling Transport Protocols

2001
Until relatively recently the Internet and PSTN networks had been developing independently of each other. While each has evolved to provide globally accessible services, the design principles of each have been very different. The initial PSTN services have been focused on conversational, real-time, applications - principally telephony.

Protocol Architectures: SS7 and TCP/IP

2003
This chapter presents an overview of SS7 and TCP/IP architectures. It describes the key components of each type of architecture, its protocols, and a list of issues to consider.

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

IEEE Communications Surveys & 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 implementation of SS7 in JSU-16000

Proceedings of International Conference on Communication Technology. ICCT '96, 2002
An important aspect in the development of communication networks is the development of signalling technology. SS7 is a common channel signalling system recommended by CCITT, which is adapted to the development of ISDN and IN. This paper presents a general scheme to implement SS7 in JSU-16000, a fully distributed control digital switching system, that ...

Evolving intelligent interexchange network-an SS7 perspective

Proceedings of the IEEE, 1992
The role of common channel signaling, referred to as Signaling System No.7 (SS7), in the evolution of services in an interexchange carrier environment is discussed. The importance of SS7 in evolving the intelligent network necessary to support these services is addressed.

Call-routing analysis using SS7 data

Bell Labs Technical Journal, 2005
Signaling System 7 (SS7) data contains network usage information that is not available from any other source. SS7 data is standalone source data. Because it is not dependent on a support system or on switch translations, it can be used to accurately trace and time all calls entering or leaving any class 4 or class 5 switch.

Better Protection of SS7 Networks with Machine Learning

2016 6th International Conference on IT Convergence and Security (ICITCS), 2016
Deregulation and migration to IP have made SS7 vulnerable to serious attacks such as location tracking of subscribers, interception of calls and SMS, fraud, and denial of services. Unfortunately, current protection measures such as firewalls, filters, and blacklists are not able to provide adequate protection of SS7.
