Mobile communication is definitely one of the major high-technology applications that offer present-day people a modern life of appropriate convenience. In recent years, the third generation cell-phone system has approached maturity. The Universal Mobile Telecommunication System (UMTS) is currently the most widely used system around the world. The 3rd Generation Partnership Project is equipped ...

With the improvement of telecommunication and wireless Internet-access technologies, smart mobile terminals have been extensively applied for mobile shopping. In this paper, PPM Model is taken as a theoretical framework and an empirical research method is employed to determine the antecedents influencing consumers’ decisions on migrating from PC-based shopping to mobile shopping. We found that ...

It should be noted that there are widely varying definitions of the term ̀ agent'. This document will not attempt to provide an authoritative definition, but will mention some qualities shared by most agents and raise some of the inherited problems associated to these concepts. A software agent is a piece of software which acts to accomplish tasks on behalf of its user. Many agents are based on ...

In this paper, we propose a new type of parallel genetic algorithm model for multi objective optimization problems. That is called a ”Master-Slave model with Local Cultivation model (MSLC)”. To clarify the characteristics and effectiveness of this model, the proposed model and the various EAs are applied to solve an antenna arrangement problem of mobile telecommunication. Thorough this problem,...

In this paper, a data dissemination technique is introduced for cellular networks by embedding peer-to-peer data transfer into the hierarchical architecture of UMTS (Universal Mobile Telecommunication Systems) for cooperative sharing of data among mobile terminals. Our concept is based on the uplink/downlink traffic imbalance in 3G wireless networks and clearly confirms the social principle ‘‘r...

In recent years, large-volume contents delivery have been growing and P2P technology has been a roaring success. However, P2P have some inherent problems, and it would bring severe effect in mobile internet. For example, excessive equality between two peers burdens the backbone network; the security defect worries all of users, etc. To solve this problem, we propose a new telecommunication mode...

Recovery from transient failures is one of the prime issues in the context of distributed systems. These systems demand to have transparent yet efficient techniques to achieve the same. Checkpoint is defined as a designated place in a program where normal processing of a system is interrupted to preserve the status information. Checkpointing is a process of saving status information. Mobile com...

Mobile telecommunication systems such as General Packet Radio Service (GPRS) and Universal Mobile Telecommunications System (UMTS) provide packetswitched service for mobile terminals. 3GPP Release 4 and Release 5 further offer packet voice over a GPRS/UMTS infrastructure so that IP based communications between mobile to mobile is expected to be one of the major traffic types in the future 3G Al...

Major African cities came recently in the age of digital communications, mainly through the uprising of mobile phone networks which have experienced an impressive growth throughout the continent. The development of the continent mobile telecommunication market is providing many advantages in the economic, social and human fields, changing rural and urban populations access to information in mos...
