Traffic dimensioning for GSM-over-IP services
M. Fiacco · 2004
The cost of the link connecting the backbone network and customer premises has a major effect on the uptake of IP-based wireless office technology. The paper describes the factors influencing the dimensioning of this link, by taking into consideration a system which uses the IP network in order to deliver voice and signalling to a GSM radio access system. Through simulation, it is shown that discontinuous transmission for the voice traffic offers a reduction in the bandwidth requirements, and makes the system more resilient to short periods of congestion. The results presented can be employed in order to dimension link requirements for GSM-over-IP services.
