3GPP has specified that terminals can be configured to use either 2 or 10 ms transmission time interval in high speed uplink packet access systems. The purpose of this paper is to evaluate the benefit of exploiting a mixture of both of the transmissions time intervals within a cell instead of only one. The study is quantified by means of studying the achievable coverage of voice over IP and possible...
As VoIP applications become increasingly popular, voice quality remains the user's biggest concern. Peer-to-Peer network can potentially obtain qualified relay nodes (QRNs) to make path switching when the QoS of a default path degrades. Locating quality relay nodes rapidly and inexpensively however is a very challenging task. In this paper, we design and develop a sophisticated system to take snapshots...
VoIP (Voice over Internet Protocol) is a technology that enables the routing of voice conversations over any IP-based network such as the public Internet. Separate and distinct client, gateway and call control functions that ability to support Peer-to-Peer, PC-to-telephone, telephone-to-PC and telephone-to-telephone scenarios. During transmission, the traffic loading and other factors in the IP (Internet...
