This paper presents a study of packet data services over wireless connections in the context of Universal Mobile Telecommunication System (UMTS). To perform the study an emulator of the radio access part has been made which includes the mobile terminal and the UMTS Terrestrial Radio Network (UTRAN). The main features, the validation procedure and some results are contained.

One of the purposes of receive filtering in the Universal Mobile Telecommunication System (UMTS) terminal receiver is to provide channel selection selectivity. This enables the terminal to receive a desired signal in the presence of interfering signals. The worst case interference conditions in which an UMTS terminal still has to operate are defined by a number of conformance tests in the UMTS ...

In universal personal telecommunication (UPT) environments, UPT networks retain information related to incall/outcall registration in UPT user service profiles in order to provide incoming UPT calls for UPT users in any location who have registered at a terminal. As UPT networks support incall registration, terminal users can be different from terminal owners, and several UPT users can register...

Abstract: In the teletraffic engineering of all the telecommunication networks, parameters characterizing the terminal traffic are used. One of the most important of them is the probability of finding the called (B-terminal) busy. This parameter is studied in some of the first and last papers in Teletraffic Theory. We propose a solution in this topic in the case of (virtual) channel systems, su...

The investigation of structural graphs has many fields of applications in engineering, especially in applied sciences like as applied chemistry and physics, computer sciences and automation, electronics and telecommunication. The main subject of the paper is to express fragmentation criteria in graph using a new method of investigation: terminal paths. Using terminal paths are defined most of t...

This paper investigates the role of pitch accent information in spoken-word recognition in listeners in Fukushima, Japan, whose dialect is accentless. Previous research revealed that accentless listeners were less sensitive to pitch accent than Tokyo Japanese listeners. The present study asked whether middle-aged listeners’ use of accent information would differ from that of young listeners. 40...
