TBF (Temporary block flow) are the radio resources assigned to each mobile between MS and PCU during a GPRS-EDGE connection.
There are many TBF’s for each time slot because it is the principle of GPRS to share radio resources between many users.
I am interrest by the GPRS system , radio parameters, point of view for the optimization .Can anyone help me and give me the list of the necessary parameters using and the good threashold for QOS of the GPRS .
OK..General Package Radio System
#copy paste from (ERICSSON)
((The GPRS system provides a basic solution for Internet Protocol
(IP) communication between Mobile Stations (MS) and Internet
Service Hosts (IH) or a corporate LAN. This is done with:
· Efficient use of scarce radio resources
· A flexible service, with volume-based (or session durationbased)
· Fast set-up/access time
· Efficient transport of packets in the GSM network
· Simultaneous GSM and GPRS, co-existence without
· Connectivity to other external packet data networks, using
The solution for IP communication between MS and IH permits
services beyond those that GSM can provide, allowing customer
segments beyond those using GSM today. Machine-to-machine
communication is one example of possible services.
