NGN Signalling:SIGTRAN, SIP, H.323, BICC Training

This course is aimed at providing the student with a detailed overview of the control (signalling) protocols emerging in Next Generation Network (NGN) architectures including interworking both within and outwith NGNs.

For over two decades telecommunication networks have been adopting Signalling System #7 (SS7/C7) for the exchange of control information (signalling) between network entities. The ubiquitous deployment of SS7/C7 will become something of the past as control protocols suited for NGN packet based telecommunications are rolled out eating into former SS7/C7 space.

NGNs introduce greater technical complexity including more protocols. Many of the protocols are complimentary in nature, whereas others are directory competitive. In terms of NGN signalling protocols, the protocols may be used in various complimentary configurations, but in other scenarios the protocols compete with each for dominance. The course aims at arming the student with the knowledge of what protocol may be used where, how and why, along with some protocol specifics.

It is critical that those involved with telecommunications understand the revolution taking place. For those involved in telecommunications on a deeper level it is critical to understand the emerging NGN protocols; their purpose, pros and cons, associated architectures, background, future deployment and interworking scenarios.

The course provides an overview of the packet based signalling protocols: SIGnaling TRANsport (SIGTRAN), H.323, Session Initiation Protocol (SIP), and Bearer Independent Call Control protocol (BICC). The overviews are provided in an integrated way so that students should understand how the protocols relate to each other, how they may work together, protocols specifics, service possibilities and interworking methods both between themselves, the current PSTN and their use within third generation (3G) cellular networks.
