Aegean Chou aegean2000 at 21cn.comDear all, the bts arround me uses MultiCCCH, it's CCCH_CONF = 110 (6), so it uses TS0, TS2, TS4 and TS6 in a frame for PCH/AGCH. but the burst_ind only CCCH-CONF 0 & 1 are supported, it can sniff TS0 only, so only catch 1/4 IMM ASS for me. my OWN phone, it's just not in TS0 (i use nokia netmonitor to check it), so i can't catch it at all (phones use IMSI to decide page group). i read the source briefly, and modify prim_rx_nb.c line "l1s_rx_win_ctrl(arfcn, L1_RXWIN_NB, 0);" for TS2, TS4, TS6 temporarily, but this way i'll need 4 phones to catch ONE station. it's very strange, and not beauty. i think the bottleneck is the DSP, as the DSP task (ALLC_DSP_TASK) can only process one TS of a frame (it's enough for phone), i think maybe backup/restore the DSP task variable patch needed, i'm new to the DSP disassemble and patch, anyone can help? thanks Best Regards Steve
