Abstract Changes in the competitive landscape among telecommunication providers have forced the telecommunications industry to reevaluate its cost and pricing structures. Multimedia services are rapidly gaining in popularity as high-speed data connections become widespread. Enabling the delivery of new multimedia services in a standardized way thereby reducing the cost associated with the introduction of new services is the key to the success of [the] telecommunication industry. This need led to...

Abstract This work investigates and studies the performance of voice quality when sent over the ABR service in ATM networks. Sources can modify the rate at which they send traffic to the network based on the feedback carried by the Resource Management (RM) cells. This is achieved by changing the encoding level. As the contention increases in the network resources, (bandwith in this case), sources start to reduce the rate at which they generate and send traffic. The efficiency of the scheme under...

Abstract This project represents the simulated model of voice over IP in Mobile communications. In the Global System for Mobile Communication (GSM) infrastructure the signaling entities like Mobile Switching Center (MSC), Visitor Location Register (VLR) and Home Location Register (HLR) uses Mobile Application Part (MAP), which sits on the top of Transaction Capabilities Application Part (TCAP) of Signaling System no. 7. The current GSM infrastructure uses MAP and TCAP part of SS7 for...
