MTPSec: Customizable Secure MTP3 Tunnels in the SS7 Network

19th IEEE International Parallel and Distributed Processing Symposium, 2005
The signaling system 7 (SS7) is the control network used by public telephones all over the world. Having been designed in an era where few large companies controlled the entire network, SS7 has virtually no security. Due to telecommunication deregulation, liberalization of economies and the convergence of telephone, IP and wireless networks, interfaces

Estimation of SS7 traffic in UMTS network

Proceedings of GLOBECOM '95, 2002
In this paper, we present a general model for the prediction of signaling traffic in a network where the terminal mobility shares the signaling infrastructure of fixed services. The model uses state transitions to estimate calling patterns and usage of services. In addition, methods of mapping state transitions to physical movements are presented.

A scalable and reusable emulator for evaluating the performance of SS7 networks

IEEE Journal on Selected Areas in Communications, 1994
A scalable and reusable emulator was designed and implemented for studying the behavior of SS7 networks. The emulator design was largely based on public domain software. It was developed on top of an environment supported by PVM, the Parallel Virtual Machine, and managed by OSIMIS/spl minus/the OSI Management Information Service platform.

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.

Exploiting lookahead in parallel simulation of SS7 telecommunication networks

1993 Euromicro Workshop on Parallel and Distributed Processing, 2002
This paper describes techniques used to optimise the performance of parallel simulation of SS7 telecommunication networks. A basic parallel simulation model of an SS7 network and the conservative implementation of the model are discussed and experimental results on the performance of the simulator are examined.

PROMS: a PRO-active Monitoring System for SS7 networks

International Journal of Network Management, 2000
In this paper, we propose a PRO-active Monitoring System lPROMSr for SS7 networks, which actively monitors all signaling network management messages of SS7 networks, alerts operators when there is a potential network error, and provides intelligent diagnosis based on fuzzy logic and neural networks.

Performance measurements of the SS7/intelligent network

MILCOM 91 - Conference record, 2002
The author addresses the architecture of the intelligent network (IN) based on the Signaling System Hash 7 (SS7) network. He proposes and defines a system architecture design of the intelligent network based on the implementation of the SS7 network with the conventional service control points. (SCPs). This results in less likelihood of failure and more

ISDN User Part Traffic Optimization in the SS7 Network

International Journal of Interdisciplinary Telecommunications and Networking, 2013
The state of the art Long Term Evolution (LTE) mobile core networks predominantly use Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP) for transporting voice across networks. Voice-over-LTE (VoLTE) designed for LTE network based on an IP Multimedia System (IMS)) framework is the key to enriched voice communication services for ...
