In this paper packet transmission performance of USCH has been investigated. Throughput, delay, collision probability and blocking probability are obtained as function of network load for varied number of users. Effect of various other parameters such as retransmission limit, number of resources etc has been investigated. Two enhancements of the protocol… (More)
The WCDMA based 3G cellular standards have a great flexibility and a variety of logical and transport channels defined for different types of traffic classes. In this paper performance of the dedicated channel for WWW traffic has been investigated. The UMTS standard specifies the use of dedicated channels (DCH) for the actual traffic, through access… (More)
This paper addresses the UMTS system performance analysis over dedicated channels based on buffer length allocation and dynamic allocation control procedures. Throughput and access delay for packet data transmission is evaluated as a function of network load for both of the allocation procedures. A mathematical model, which can be used to analyze the… (More)
