Railway wireless communication has become an indispensable part to provide the reliability and safety of the railway operation as well as the improved railway services. In addition, advanced mobile communication technologies have triggered new railway customer services. Thanks to many benefits of the 4-generation mobile communication technology, long-term evolution (LTE), this technology is one...

This document specifies interworking between the Session Initiation Protocol (SIP) and QSIG within corporate telecommunication networks (also known as enterprise networks). SIP is an Internet application-layer control (signalling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include, in particular, telephone calls. QSIG is a signalling...

Signalling protocols are responsible for fundamental tasks such as initiating and terminating communication identifying the state of in telecommunication core networks. System No. 7 (SS7), Diameter, GPRS Tunneling Protocol (GTP) main used 2G to 4G, while 5G uses standard Internet its signalling. Despite their distinct features, especially security guarantees, they most vulnerable attacks roamin...

The functional separation of call control and the control of network resources brings about the flexibility in provision of telecommunication services. This paper addresses the relation between call control and resource control in the B-ISDN signalling. The merits and drawbacks of two complementary interaction strategies, i.e., simultaneous and sequential set-up are discussed. Principles of how...

This paper presents aspects of the integration of the enhanced capabilities of B-ISDN signalling in the field of Distributed Processing Environments for telecommunication networks, developed in the CAMOUFLAGE project. The mechanisms of operational and stream oriented object communication provided by a B-ISDN based DPE are shown. The advantages of this integrative approach in terms of building l...

The conventional telecommunication software components are mainly developed using message-passing as the underlying communication mechanisms. Recent standards on modern distributed systems, exemplified by CORBA and DCE, however, have converged to a new programming paradigm based on client/server architecture, objectoriented model, and Remote Procedure Calls (RPCs). In the near future, we envisi...

depicts requirements for signalling interfaces over which Data protection and data security become more significant since telecommunication services and innovative applications based on these services handle an increasing amount of sensitive data. Modern services, e.g. call forwarding, tele-conferencing, and voice mail services use or store personal data to implement individual services. Sensit...
