NOKIA TD-LTE VoLTE无线参数设置手册1 简介本文为NOKIA TD-LTE设备无线侧VoLTE参数设置指导手册。2 VoLTE无线参数设置指导2.1 VoLTE Call o 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2-1 actConvVoice设置o 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 beareractConvVoiceThis parameter activates the support of the conversational voice bearer.
