Personal mobility (PM) is one of key issues in realizing emerging third generation mobile communication systems such as International Mobile Telecommunication 2000 (IMT2000) and it can be realized through universal personal telecommunication (UPT) service. A PM management scheme is considered in order to manage PM information related to UPT users for incall registration/deregistration, incall r...

Abstract Value-Added Services at a Mobile Telecommunication company provide customers with variety of services. Value-added services generate significant revenue annually for telecommunication companies. Providing solutions that can relevant and engaging has become major challenge in this field. Numerous methods have been proposed so far to analyze customer basket related Although these many ap...

Nepal Telecommunication (NTC) and Ncell are the two main telecom players in at moment. has been primarily focused on offering Global System for Mobile (GSM) mobile lines, while NTC offers all types of phone services. Although remains countrys leading provider total subscribers, recently overtook as GSM lines. This study aims to assess customer satisfaction highly competitive Nepalese industries...

The performance of a multi-rate mobile cellular network using the Frequency Division Duplex (FDD) mode of the Code Division Multiple Access (CDMA) based Universal Mobile Telecommunication System (UMTS) is investigated. The new call blocking and call dropping probabilities and the tolerable network load are studied in the context of a multi-rate FDD-mode UMTS network incorporating dynamic thresh...

The objective of this work is to evaluate the Quality of Service (QoS) of a Universal Mobile Telecommunication System (UMTS) cell. Among UMTS characteristics, we focus the attention on two aspects strictly related with the identified QoS measures: the random-access procedure and the admission control strategy. Using a model-based approach, we model and evaluate a UMTS cell under several service...

With the entry of 3G and WiMAX players, the Indian mobile subscriber base is expected to reach 1110 million by the end of 2015. To meet mobile infrastructure demand, India will require approximately 350,000 to 400,000 mobile telecommunications towers in the next 7 to 8 years. Presently only 40% of mobile telecommunications towers are shared in India. The high growth of subscribers and initial c...

ODMA (Opportunity Driven Multiple Access) is an optional extension of the third generation mobile communication standard called UMTS (Universal Mobile Telecommunication System). It de-nes a special ad-hoc network, where each mobile node that wants to communicate has to connect to the base station with the assistance of the forthcoming mobile nodes. So in this ad-hoc network the destination is x...

This paper describes mobility management for the third-generation mobile networks. We focus on the evolution from General Packet Radio Service (GPRS) to Universal Mobile Telecommunication System (UMTS). In this evolution, the radio access network UTRAN has been introduced, and radio-related management is moved from the core network to UTRAN. We elaborate on how this architecture change affects ...

This paper presents a novel Time Difference of Arrival (TDoA) estimation algorithm for mobile station positioning in Universal Mobile Telecommunication System (UMTS) based on cell search procedure defined by 3GPP. Standardized method for Time Difference of Arrival (TDoA) measurement and cell search procedure are stated. Furthermore, proposed solution for TDoA parameter estimation via multichann...
