Hi all,

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.

Thanks

Hi Angie
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.

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)
billing
· Fast set-up/access time
· Efficient transport of packets in the GSM network
· Simultaneous GSM and GPRS, co-existence without
disturbance
· Connectivity to other external packet data networks, using
the IP
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.
