I have some difficulty with the term TBF in GPRS system, could anyone can help me out. Thanks.1st November 2004 at 17:39 #40099alexanderGuest
TBF – temporary block flow, it is a name for traffic flow at BSS part of GPRS. It is a flow of traffic from one user.

Any one know how to define RA ( Routong area) for GPRS in BSC Ericsson.
I think in R8 we cannot define it but in R9 and more may be yes.13th November 2004 at 15:39 #40102OliverGuest
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.17th November 2004 at 15:00 #40103bachirGuest

TBF (temporary bloch flow)
Which is managed by RX_LEV threshold used in radio link supervision in order to change the TBF coding scheme from CS-1 to Cs-2 OR CS-2 to CS-1.20th November 2005 at 05:30 #40106Hi guysGuest
Still I did not get any idea about What is GPRS. Please explain what is GPRS system.

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.
