Defining subsystems 192 (bssgs) in both elements.
Defining GT analysis in both N.E. to exchange signalling messages
Defining which LAC belong to which MSC in SGSN. This is mandatory for processing combined GPRS-GSM messages.
hi scott,
In gprs ,there is only two thing is mandotary to workout..
1. gb link betwenn bsc and SGSN
2. Gs link between msc and SGSN
in gb link there is also Gd link we have to define which is for data part and there is one link which is for signalling between bsc and SGSN it is Gd link with Lapd protcol.and anothere thing is that for every bsc u have to give DLCI which is same at both end bsc and SGSN…and most important is on which timeslot u r defining gb link must be same at SGSN side.
if more query then ask.
Hi u all,
Gs importance is for location update basically it was totally optional.But to avoid double location update by mobile every time to the GPRS and MSC side Gs interface came in picture and now only one location update is sufficient and SGSN/GGSN and MSC take care about each other related related to update.
