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.

The paper presents an end-to-end Quality of Service (QoS) architecture suitable for IP communications scenarios that include UMTS access networks. The rationale for the architecture is justified and its main features are described, notably the QoS management functions on the terminal equipment, the mapping between IP and UMTS QoS parameters and the negotiation of these parameters.

Differentiated Services (DS) is currently the major approach discussed to provide network layer service differentiation in IP networks. However, the discussion mainly addresses fixed networks. This short paper analyzes the usage of DS in cellular wireless packet networks being based on the ‘Universal Mobile Telecommunications System’ (UMTS), focusing on service provisioning within the transport...

The paper describes the architecture of an UMTS terminal equipment that provides Quality of Service (QoS) management functions for emerging 3G services in all-IP based communication scenarios. The mapping of IP and UMTS QoS parameters, the reservation procedures and the main IP traffic control mechanisms (scheduling and shaping) are discussed. The activation of a service is exemplified.

It is common knowledge that the transition of mobile networks from one generation to another basically for improvement in network’s Quality Service (QoS). Bearing this mind, we will assumme Universal Mobile Telecommunication System (UMTS) outperform Global Communication (GSM), hence, motivation conduct study Calabar, Nigeria, four networks; MTN, Airtel, Globacom and 9mobile. With aid a TEMS inv...

Due to increase of data browsing and downloading using 3G enabled mobile handset, it is often required handover mechanism from Universal Mobile Tele-communication System (UMTS) to UMTS, Long Term Evolution (LTE) or Global system for Mobile Communications (GSM) while the handset is continuously transmitting and receiving data from the connected Node-B in a high speed motion. In UMTS, the handhel...

The adoption of packet-switched technologies in mobile communication systems has enabled the provision of IPbased services to mobile users. Yet, these systems, such as the UMTS network, are unable to meet the stringent delay requirements imposed by the enhanced multimedia services due to the anchor point that introduce into the user’s data path. Moreover, such applications will rely on IP-based...

Mobile packet services are penetrating mobile markets rapidly. The mobile industry relies heavily on data services to replace traditional voice services. Designing a reliable packet service network is critical to the mobile operators’ ability to maintain their core competence in a data service market. The current literature provides many practical tools and theoretical methods to design, plan a...
