The General Packet Radio Service (GPRS) offers performance guaranteed packet data services to mobile users over wireless frequency-division duplex links with time division multiple access, and core packet data networks. This paper presents a dynamic adaptive guaranteed Quality-of-Service (QoS) provisioning scheme over GPRS wireless mobile links by proposing a guaranteed QoS media access control...

mobile phone technology means that it has become a very efficient tool. the development of tools and reduce its price, makes it all the segments of the from the old to the young do not go out of the house without their cell phone and the most essential tool with which they have. this has caused most organizations and service agencies also offer mobile services based on their. list of the quran,...

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 provides an accurate model of the General Packet Radio Service (GPRS). GPRS is modeled as a single server queue in a Markovian environment. The queueing performance of data packets is evaluated by matrix geometric methods. The arrival process is assumed to follow a two state Markov modulated Poisson process (MMPP), and the service rate fluctuates based on voice loading. The analytica...

The paper gives a method that greenhouse data collection and supervisory system based on GPRS (General Packet Radio Service) network is designed and implemented. It discusses chiefly a scheme, which uses ARM microcontroller to control GPRS module and make use of SMS(Short Messaging Service) to complete greenhouse data collection and supervision, and supplies a design program of the hardware and...

One of the stated aims of 3 Generation mobile communications systems is to provide enhanced multimedia services to the user. Such services will include an integration of video, high-quality audio and data services. This paper describes a real-time mobile video communications system which employs ETSI’s GPRS mobile packet system as a mobile access medium. Subjective performance tests are carried...

Wireless local area networks (WLAN) and General Packet Ratio Service (GPRS) networks are two of the most widely used wireless network systems. In this paper, we propose a mobility support for mobile host roaming between WLAN and GPRS networks. In addition, a handoff decision model is presented to reduce the latency of the handoff procedure. The experimental results, including throughput, packet...

The general packet radio service (GPRS), a data extension of the mobile telephony standard GSM is emerging as the ®rst true packet-switched architecture to allow mobile subscribers to bene®t from high-speed transmission rates and run data applications from their mobile terminals. A high-level description of the GPRS system is given with emphasis on services and architectural aspects. Ó 2000 Els...
