Recent years have seen a dramatic increase in demand for mobile communication services and with the introduction of 2.5G services such as GPRS, this trend is expected to increase further. The highly dynamic and bursty nature of packet switched services such as GPRS will require a much more flexible method of radio resource management so as to maximise system resources compared to currently empl...

Throughout the world, GSM cellular mobile networks are being upgraded to support the “always-on” General Packet Radio Service (GPRS). Despite the apparent availability of levels of bandwidth not dissimilar to that provided by conventional fixed-wire telephone modems, the user experience using GPRS is currently considerably worse. In this paper we examine the performance of TCP and HTTP over GPR...

The method of sluice control applied to reservoir is executed manually in field at present. To fix this problem, sluice remote monitoring system based on GPRS and PLC is provided. Some advanced technologies used in system are discussed. The system structure and principle are introduced. The system realizes wireless network connections between local control unit and center control unit based on ...

BACKGROUND Despite significant gains made toward improving access, early infant diagnosis (EID) testing programs suffer from long test turnaround times that result in substantial loss to follow-up and mortality associated with delays in antiretroviral therapy initiation. These delays in treatment initiation are particularly impactful because of significant HIV-related infant mortality observed ...

There has been an increasing demand for wireless data services due to the popularity of Internet services and circuit-switched (CS) systems are not appropriate for accommodating bursty data traffic. The wireless data services can be efficiently supported in the packet-switched (PS) system and General Packet Radio Service (GPRS) is a representative PS system which is being serviced widely. In GP...

Packet-switched non real-time data transmissions have increased a lot in the fixed network. Circuit-switched based cellular transmission techno logy Global System for Mobile communications (GSM) is already in the service for more than a decade. A packet based transmission system called General Packet Radio Services (GPRS) is developed for non real-time packet data transmission system by the evo...

GPRS is now deployed and commercially open in a vast number of networks worldwide. The forthcoming generalization of multimedia mobiles with advanced capabilities, along with continuing efforts to optimize the end-to-end performance, are expected to trigger an exponential soaring of traffic. EDGE or UMTS are the possible network evolutions to handle it. A number of important technical challenge...

AIM Develop and pilot test evidence-based resources for general practice training practices to enhance older patients' (65+ years) interactions with General Practice Registrars (GPRs). BACKGROUND In Australia, general practice trainees, referred to as GPRs, see fewer older patients and patients with chronic conditions than doctors who have completed their specialist GP training. This reduces ...

The Global System for Mobile Communications (GSM) Phase 2+ standard specifies a type of packet data service called General Packet Radio Service (GPRS). GPRS allows dynamic allocation of bandwidth resources. Wireless channels are allocated to a Mobile Station based on its demand. A communication session may last for an extended period of time with intermittent packet transmissions. This paper in...
