1、小区计算公式1.TCH掉话率=TCH掉话次数/TCH占用次数call_s_post_c_tch/(total_calls+assgn_redirect)2.SD掉话率=SD掉话次数/SD占用次数rf_losses_sd/alloc_sdcch3.TCH拥塞率=TCH拥塞次数/TCH占用次数ma_cmd_to_ms_blkd/(total_calls+assgn_redirect)4.SD拥塞率=SD拥塞次数/SD占用次数+SD拥塞次数alloc_sdcch_fail/(alloc_sdcch+alloc_sdcch_fail)5

2、.TCH分配失败率=TCH分配失败次数/TCH占用次数ma_req_from_msc-ma_complet_to_msc/(total_calls+assgn_redirect)6.SD分配失败率=SD分配失败次数/SD占用次数(alloc_sdcch-ok_acc_proc)/alloc_sdcch7.切换成功率=切换成功次数/切换请求次数(i_inter_bs_ho_suc+i_intra_bs_ho_suc+o_inter_bs_ho_suc+o_intra_bs_ho_suc）/（ho_req_ak_msc_tot+i_
