INTRODUCTIONTraffic emulation is an essential research phase towards the deployment of the UMTS. Wepresent here an extension to the traffic generator TG which enables to generate the four UMTStraffic classes proposed by the 3GPP.2. TRAFFIC MODELIn [1] the 3rd Generation Partnership Project (3GPP) has defined four classes of services thatneed to be provided in UMTS. To characterise a single-user traffic, we fit each of these classesin a three-level model [2]. Here is a quick run-down of their signification: the session-level lastsas long as the application is running, its statistics are mainly influenced by user behaviour. Theconnection-level describes the connection behaviour of a single session, the pattern chosen forour sources is based on an On-Off (High-Low) model in which it is possible to generate trafficon both states. Finally, for each state of the connection-level, the packet-level describes thepacket inter-arrival and size distribution. Based on this level division, we have modeled the fourtraffic classes in terms of statistical distributions, in line with literature [2,3] or 3GPP standards[4,5] when applicable. To generate these different traffics, we used an enhanced version of Traffic Generator (TG1)implementing  the  Pareto  distribution  as  well2.  We  simulated  five  User  Equipments  (UE)connected to the same NodeB, each of them generating and receiving all kinds of traffic during50,000 seconds (about 14 hours). The simulation took place on our UMTS testbed3. In order tosimultaneously emulate several autonomous UEs, we coded a control panel based on multi-thread programming and virtual network interface management. The role of this control panel isto facilitate the UE management by delegating them a single thread and an IP address.3. REFERENCES[1] Technical Specification Group Radio Access Network.
