Reply To: SDCCH dimensioning for HR environment


hello all

during location update , the MS sends its old LAC and TMSI to the BSC . If somehow TMSI is not recongnizable then MS is asked for the IMSI no.
My question is why doesn’t the MS sends IMSI first time only ? Why does it send the TMSI first?

thanks in advance
