hodec2 log: less verbose, more concise logging
Drop numerous log statements that merely bloat the ho decision log. Logging HO candidates: log more compact in a single line, do not use LOGPC and multiline output. The result is more useful information in a quarter of the log lines. LOGPHOLCHAN(), LOGPHOLCHANTOBTS(): - log lchan->type instead of lchan->ts->pchan - always log the speech mode ===== Before ===== DHODEC handover_decision_2.c:1131 (lchan 0.010 TCH/F) (subscr IMSI:000001) MEASUREMENT REPORT (1 neighbors) DHODEC handover_decision_2.c:1136 (lchan 0.010 TCH/F) (subscr IMSI:000001) 0: arfcn=871 bsic=63 neigh_idx=0 rxlev=30 flags=0 DHODEC handover_decision_2.c:261 (lchan 0.010 TCH/F) (subscr IMSI:000001) neigh 871 rxlev=30 last_seen_nr=3 DHODEC handover_decision_2.c:1158 (lchan 0.010 TCH/F) (subscr IMSI:000001) HODEC2: evaluating measurement report DHODEC handover_decision_2.c:1175 (lchan 0.010 TCH/F) (subscr IMSI:000001) Measurement report: average RX level = -110 DHODEC handover_decision_2.c:1190 (lchan 0.010 TCH/F) (subscr IMSI:000001) Virtually improving RX level from -110 to -105, due to AFS bias DHODEC handover_decision_2.c:1220 (lchan 0.010 TCH/F) (subscr IMSI:000001) Attempting handover/assignment due to low rxlev DHODEC handover_decision_2.c:899 (lchan 0.010 TCH/F) (subscr IMSI:000001) Collecting candidates for Assignment and Handover DHODEC handover_decision_2.c:407 (lchan 0.010 TCH/F)->(BTS 0) (subscr IMSI:000001) tch_mode='SPEECH_AMR' type='TCH_F' DHODEC handover_decision_2.c:313 (lchan 0.010 TCH/F) (subscr IMSI:000001) FR3 supported DHODEC handover_decision_2.c:313 (lchan 0.010 TCH/F) (subscr IMSI:000001) HR3 supported DHODEC handover_decision_2.c:489 (lchan 0.010 TCH/F)->(BTS 0) (subscr IMSI:000001) removing TCH/F, already on TCH/F in this cell DHODEC handover_decision_2.c:573 (lchan 0.010 TCH/F)->(BTS 0) (subscr IMSI:000001) TCH/H would not be congested after HO DHODEC handover_decision_2.c:605 (lchan 0.010 TCH/F)->(BTS 0) (subscr IMSI:000001) TCH/H would not be less congested in target than source cell after HO DHODEC handover_decision_2.c:609 (lchan 0.010 TCH/F)->(BTS 0) (subscr IMSI:000001) requirements=0x30 DHODEC handover_decision_2.c:704 - current BTS 0, RX level -110 DHODEC handover_decision_2.c:707 o free TCH/F slots 3, minimum required 0 DHODEC handover_decision_2.c:709 o free TCH/H slots 4, minimum required 0 DHODEC handover_decision_2.c:714 o no requirement fulfilled for TCHF (no assignment possible) DHODEC handover_decision_2.c:737 o requirement A B fulfilled for TCHH (not congested after assignment) DHODEC handover_decision_2.c:407 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) tch_mode='SPEECH_AMR' type='TCH_F' DHODEC handover_decision_2.c:313 (lchan 0.010 TCH/F) (subscr IMSI:000001) FR3 supported DHODEC handover_decision_2.c:313 (lchan 0.010 TCH/F) (subscr IMSI:000001) HR3 supported DHODEC handover_decision_2.c:563 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) TCH/F would not be congested after HO DHODEC handover_decision_2.c:573 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) TCH/H would not be congested after HO DHODEC handover_decision_2.c:595 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) TCH/F would not be less congested in target than source cell after HO DHODEC handover_decision_2.c:605 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) TCH/H would not be less congested in target than source cell after HO DHODEC handover_decision_2.c:609 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) requirements=0x33 DHODEC handover_decision_2.c:701 - neighbor BTS 1, RX level -110 -> -80 DHODEC handover_decision_2.c:707 o free TCH/F slots 4, minimum required 0 DHODEC handover_decision_2.c:709 o free TCH/H slots 4, minimum required 0 DHODEC handover_decision_2.c:712 o requirement A B fulfilled for TCHF (not congested after handover) DHODEC handover_decision_2.c:737 o requirement A B fulfilled for TCHH (not congested after handover) DHODEC handover_decision_2.c:914 (lchan 0.010 TCH/F) (subscr IMSI:000001) adding 2 candidates from 1 neighbors, total 2 DHODEC handover_decision_2.c:1020 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) Best candidate, RX level -80 DHODEC handover_decision_2.c:625 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) Triggering Handover DHODEC handover_decision_2.c:688 (lchan 0.010 TCH/F)->(BTS 1) (subscr IMSI:000001) Triggering handover to TCH/F, due to low rxlevel DHO handover_logic.c:133 (BTS 0 trx 0 ts 1 lchan 0 TCH/F)->(BTS 1 lchan TCH_F) Initiating Handover...
