The world of telecommunications changed significantly with the introduction of Common Channel Signalling System #7 (SS7) and Advanced Intelligent Networks (AIN/IN). As a consequence of the SS7/AIN model's flexibility and power this architecture is now, universally, the basis of value-added service enhancement on Cable and Mobile networks as well as the classic PSTN. With the rollout of high speed, feature rich 2.5G, 3G and 4G mobile platforms todays Mobile networks offer unparalled opportunities for new and exciting applications. SIGTRAN, by enabling extension of the SS7 network into the IP (Internet) world, is the enabling technology to facilitate development of value-added services for the PSTN, VoIP, Cable and Mobile networks. As all the service providers move toward a triple play world, the imagination may become the limiting factor in service development.
The challenge facing Service Providers in the VoIP, PSTN, Cable and Mobile worlds is to overcome knowledge and cultural barriers to leverage the underlying technologies into business opportunities. Traditional core equipment suppliers face similar cultural barriers that may seriously limit their growth opportunities. The new generation of Softswitch suppliers, middle-ware vendors and value-added developers need to bring marketing, support and development staff up to speed with these challenging technologies.
|Telecommunications Technologies||Telecommunications Technologies is not a bits and bytes course but rather gives students an understanding about how all the pieces fit together and how they can be leveraged into business opportunities. Students learn about the growth and development of the PSTN, Cable, Mobile and Internet worlds.
SS7 and SIGTRAN protocols, being critical infrastructure, are covered in sufficient detail to allow students to appreciate their capabilities and power and extensive use is made of call animation scenarios to enable students to visualize where, and how, value-added call processing can be added. VoIP (SIP) functionality is described and mapped onto its equivalent functionality in the traditional telephony world (Mobile, PSTN). At the end of the course students design, and outline the implementation of, value added services for PSTN, Mobile, Cable and VoIP networks.
