Moving to TCH without doing a BCCH again when using app_ccch_scan

In one of the ML I have read that, BCCH-SDCCH-BCCH-TCH is required for
listen to the TCH.
In my case(Test N/w) I receive an IMM ASS, go to (SDCCH/4 + SACCH/4) TS:0
As soon as I find an ASS_CMD I send a l1ctl_tx_dm_est_req with new channel
parameters and jump to a TCH/F+SACCH/F+FACCH/F TS 4. I am receiving bursts
They contain SACCH SI5/6 as I see them in Wireshark and also some bursts (I
hope a mix of FACCH and TCH). Is it necessary to do BCCH again. If I don't
do Won't I receive TCH frames.? Will the be good TCH frames. ?
But I see the tch_schedule_set working good. I receive once UL and next DL
bursts. and sometimes SACCH.
Can someone explain me.
