In system information type 3 I got the following info: Control Channel Description 1 . . . . . . . = MSCR: MSC is Release ’99 onwards (1) . 1 . . . . . . = ATT: MSs in the cell shall apply IMSI attach and detach procedure (1) . . 00 1 . . . = BS_AG_BLKS_RES: 1 . . . . .110 = CCCH-CONF: 4 basic physical channels used for CCCH, not combined with SDCCCHs (6) . 00 . . . . . = CBQ3: IU mode not supported (0) . . . . . 110 = BS-PA-MFRMS: 6
This is the only info I got about CCCH description. I’m not sure if this is enough for telling that paging is done on other than timeslot 0.
