ALCATEL_GSM A1353RA B10版无线参数详解 CELL参数详解 Cell Description：小区信息描述参数 Cell Name：各地不同 Location Name：可以不填 PLMN Name: Own PLMN BCCH Channel： 1 配置的BCCH信道的数目 Static SDCCH： 8 配置的静态SDCCH信道的数目 按照规划做，根据ErlB表算出SDCCH话务负荷。 Dynamic SDCCH：0 配置的动态SDCCH的数目 默认设置为0，一般来讲对于SDCCH突发拥塞且次数不多的小区可以添加动态SDCCH的信道配置。 Traffic Channel：6 配置的TCH业务信道的数目 按照规划做，根据ErlB表算出TCH话务负荷，一般情况下：市区blocked2%，乡镇blocked5%。 NCC Permitted：NCC Permitted (OMCR) 允许的NCC 【默认设置为全选】 Definition：Indicates which NCC values the MS considers as belonging to the network。 Spec reference：System information management Coding rule： Coded over 8 bits. each bit corresponds to a NCC value: MSB corresponds to NCC = 7, LSB。corresponds to NCC = 0. For each bit:0= NCC not permitted, 1= NCC permitted。 External comment： The value depends on configuration. The default value indicated here is for implementation purposes。 Internal comment：This parameter was previously named: “PLMN_permitted”。 Definition： This flag indicates to the MS if it reports a HANDOVER FAILURE in case of out of range timing Spec reference：External channel changes。 Coding rule：0→Out of range timing advance is ignored；1→ Out of range timing advance triggers a Handover。 Minvalue：0；Maxvalue：255；Defvalue：0。CodedMin：0；CodedMax：255；CodedDef：0。Unit：None。 BCCH_FREQ：BCCH_FREQ (OMCR) 67 【BCCH频点】 Definition：Indicates the frequency used as BCCH. Spec reference：Handover Preparation. Mandatory rule：In a cell where FREQUENCY_RANGE = “EGSM” or “EGSM-DCS1800”, the BCCH ARFCN belonging to the G1 band may be selected by the operator, only if. Recommended rule：EGSM_RR_ALLOC_STRATEGY0, and, for the concentric cells, only in the outer zone.These restrictions do not apply to external cells. Internal comment：The ARFCN of the G1 band are in the range {975, 976, …, 1023, 0}.For an own cell, the BCCH frequency is deduced from the radio TS description. Minvalue：0；Maxvalue：1023；Defvalue：None。CodedMin：0；CodedMax：1023；CodedDe
