利用110報告檢查全網(wǎng)隱形故障載頻

1、利用110報告對全網(wǎng)載頻隱性故障排查上海貝電時鵬春節(jié)鄰近，為更好的保障定西移動通信網(wǎng)絡(luò)春節(jié)期間的正常運(yùn)行，為廣大用 戶提供高質(zhì)量的服務(wù)，木周我們對全網(wǎng)載頻硬件隱形故障進(jìn)行了排查。排查的方式為：話務(wù)報告和rms跟蹤相結(jié)合。首先我們根據(jù)llocounter中的 mc370和mc38o來計算每塊載頻的平均tch占用時長，或根據(jù)hocounter的 mc390和mc400來計算每塊載頻sdcch平均占用時長。初步篩選出了tch占用 時長較短或sdcch占用時長較長，且占用次數(shù)較多的載頻。tch 平均占用時長=mc380(time_trx_busy)/mc370 (nb_trx_alloc)c370ac
