Hi All…
Can anybody explains the parameter NSEI (New Establishment Causes Support)..NOKIA BSS..its default value is either Y/N…
Wat is the effect of keeping its value Y and or N…
is it used in Call establishment or it is a Handover related parameter..Mr. Pix can u give some idea…??
Regards,
MohitSrry its NECI not NSEI…
if anyone could explain also the parameter NSEI and NSVCI.
ThanksNSE identifies a group of NS-VCs in the BSC.
The BSC uses NSEI to determine the NS-VCs which provide service to a BVC.
At the BSSGP level the NSEI has only local significance at each end of the Gb interface.
Hi,
in Channel request message(MOC or Answer to paging) if NECI=off 3bit used for establishment cause and 5 bits used for Random reference in the case of NECI = on vice versa so we have more Establishment cause messages in situation.Hi Dariush,
Do u mean if we have NECI=ON, the call establishment rate is increased…??
Does it effect the HOSR also..??
regards, Mohit
cause for access demands (RACH) is coded on 2 octets. this mean it can take up to 256 value (0 to ff in hexa). With NECI “off” not all cause are considered valid (which means not all value for access demand are acceptable) , With NECI “on” all cause are acceptable (even if theory there are still 3 or 4 cause that are reserved for future used). There’s strictly no effect except on phantom Rach. if decoded cause for this phantom is one which was discraded when NECI “off” it will no longer be discarded.
what is NSEI????
If NECI is OFF . . . you will see NO half rate traffic my friend !!
rgrds,
In GPRS protocol stack, every unique BSSGP Virtual
Connection (BVC) that is NSEI+BVCI for each
GPRS cell belongs to Network Service Entity (NSE).
NSEI uniquely identifies every NSE. Generally, one
BSC is divided into one service entity.
