NOKIA TD-LTE VoLTE无线参数设置手册简介本文为NOKIA TD-LTE设备无线侧VoLTE参数设置指导手册。VoLTE无线参数设置指导VoLTE Call 基站支持VoLTE Call只需要打开actConvVoice这个参数即可，现网这个参数已经打开了，并且已更新到开站模板里，所以开启Volte功能时，不用修改此参数。图2-1actConvVoice设置VoLTE Call（audio）使用QCI=1的专用承载，需要同时确认QCI=1支持和Qos配置。图2-2 QCI=1设置表2-1 VoLTE Call参数列表参数级别参数名Remark参数缩写参数意义推荐值LNBTSActivate support of conversational voice bearer?actConvVoiceThis parameter activates the support of the conversational voice bearer. The change becomes active for a cell after the next cell locking/cell unlocking sequence.TRUELNBTSMaximum GBR downlinkqciTab1maxGbrDlThis parameter specifies the maximum value of the GBR in the downlink direction.eNB will reject those EPS bearers with QCI1 for which the GBR in downlink direction is greater than this value.144LNBTSMaximum GBR uplinkqciTab1maxGbrUlThis parameter specifies the maximum value of the GBR in the uplink direction.eNB will reject those EPS bearers with QCI1 for which the GBR in uplink direction is greater than this value.144LNBTSQCI supportqciTab1qciSuppThe Resource Type indicates whether bearer is a GBR or NON-GBR bearer.The Resource Type determines if dedicated network resources related to a service or bearer level Guaranteed Bit Rate (GBR) value are permanently allocated.enableVoLTE CallVoLTE Call需要同时建立QCI=1和QCI=2的承载（语音1，图像2）。因此需要在LNBTS中打开actEnhAcAndGbrServices、actmultGbrbearers和actMultBearers，现网这3个参数已经打开了，并且已更新到开站模板里，所以开启Volte功能时，不用修改这些参数。图2-3 VoLTE Call参数设置QCI=2支持和Qos配置图2-4 QCI=2参数设置表2-2 VoLTE Call参数列表参数级别参数名Remark参数缩写参数意义推荐值LNBTSActivate enhanced AC and GBR services?actEnhAcAndGbrServicesThis parameter activates support of the following featuresARP based Admission Control (LTE534), Smart Admission Control, comprising RAC and TAC (LTE497) andEPS bearers with QCI 2, 3 and 4 (LTE496).Feature LTE496 introduces support of QCI 2, 3, and 4 along with higher guaranteed bit rates and related congestion detection and handling mechanisms.Admission control functionality (LTE497) is extended at the same time from a counter
