The paper presents results from an analysis of traffic measurements taken at the G/sub b/ interface of a GPRS network. Data was captured in one-week long data sets between November 2002 and March 2004. The paper provides new results, based on three of these data sets, and extends our previous work (Ivanovich, M.

Scalable gateway GPRS support node for GPRS/UMTS networks
Proceedings IEEE 56th Vehicular Technology Conference, 2003In GPRS (general packet radio service) and UMTS (Universal Mobile Telecommunications System) networks, GGSN (gateway GPRS support node) serves as a default gateway while MSs (mobile stations) connect to outside networks such as the Internet. According to the GPRS/UMTS specifications, a fixed GGSN is assigned to serve an MS that attaches to the network ...

17th International Conference on Advanced Information Networking and Applications, 2003. AINA 2003., 2003
We study the performance of VoIP over GPRS by simulation of standard GPRS system with some improvement for real time attributes. It is showed that the VoIP over GPRS has more capacity than circuit switch voice while guaranteeing acceptable QoS. With one radio frequency, the circuit switch system can provide 7 voice connections, while VoIP over GPRS can

A portrait of a GPRS/GSM session
2003Some results from a GPRS/GSM traffic measurement are presented. First we define session arrivals, durations and volumes in such a way that they can be compared, for example, with measured values of dial-up sessions. Then we study the map of cumulative volume of a single session against elapsed time from the first observed packet of the session.
