This article provides an overview of General Packet Radio Service (GPRS). GPRS reuses the existing GSM infrastructure to provide end-to-end packet-switched services. Benefits of GPRS include efficient radio usage, fast set-up/access time and high bandwidth with multiple timeslots. GPRS also provides a smooth path for GSM evolution to the third generation mobile network. Specifically, a third ge...

The General Packet Radio Service (GPRS) is widely deployed in second and third generation mobile cellular networks. Special benefits of GPRS are mobility management as well as support of authentication, authorization, and accounting (AAA). However, the data rates of GPRS are low and the price is high, compared to wired networks or Wireless LAN. Furthermore, Wireless LAN hotspots are starting to...

This paper presents the design and analysis of GPRS-WLAN Mobility Gateway (GWMG) for the integration of GPRS and wireless LANs (WLANs). The interworking between GPRS and WLANs is achieved by the GWMG that resides on the border of GPRS and WLAN systems. The design goal is to minimize the modifications in GPRS and WLANs as both systems are widely available in the market already. By deploying the ...

General Packet radio service (GPRS) is designed for transmitting packet data and supposed to take its radio resource from the pool of unused channels by GSM voice services. Obviously, the introduction of GPRS has impact on the voice services. In this paper, we present a method to calculate the outage probability of the GSM-GPRS network for both the non-frequency hopping and the frequency hoppi...

This paper proposes a new technique for Mobile IP (MIP) registration by WLAN host (WH) of the Internet through GPRS network. The home agent (HA) of WH resides in the Internet. The gateway GPRS Support Node (GGSN) provides foreign agent (FA) functionality for WH in GPRS. After successful attachment with GPRS network in roaming scenario, WH needs two mandatory passes for MIP registration with HA....
