1、需求
客户需求，5G手机在部分场景需要显示成5G+。当带宽大于50M时，显示5G+。
2、Android对应接口
2.1、MTK 平台
04-24 09:55:15.854 1917 2026 D RILJ : [UNSL]< UNSOL_PHYSICAL_CHANNEL_CONFIG [{mConnectionStatus=PrimaryServing,mCellBandwidthDownlinkKhz=15000,mCellBandwidthUplinkKhz=0,mNetworkType=LTE,mFrequencyRange=MID,mDownlinkChannelNumber=2147483647,mUplinkChannelNumber=2147483647,mContextIds=[-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 1, 2],mPhysicalCellId=487,mBand=0,mDownlinkFrequency=0,mUplinkFrequency=0}, {mConnectionStatus=SecondaryServing,mCellBandwidthDownlinkKhz=80000,mCellBandwidthUplinkKhz=0,mNetworkType=NR,mFrequencyRange=HIGH,mDownlinkChannelNumber=2147483647,mUplinkChannelNumber=2147483647,mContextIds=[-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 1, 2],mPhysicalCellId=19,mBand=0,mDownlinkFrequency=0,mUplinkFrequency=0}] [PHONE0]
可以通过ServiceState.java的getCellBandwidths获取对应带宽
public int[] getCellBandwidths() {return mCellBandwidths == null ? new int[0] : mCellBandwidths;
}2.2、高通平台
高通平台Log中找了一圈，也没找到对应判断带宽的接口，最后在QMI中中找到对应代码
rildata::NrIconEnum_t convertUiMask(const dsd_sys_ui_mask_v01& ui_mask) {if (0 != (QMI_DSD_UI_MASK_3GPP_5G_UWB_V01 & ui_mask)) {Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask UWB");return rildata::NrIconEnum_t::UWB;} else if (0 != (QMI_DSD_UI_MASK_3GPP_5G_BASIC_V01 & ui_mask)) {Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask BASIC");return rildata::NrIconEnum_t::BASIC;} else {Log::getInstance().d("[DSDModemEndPointModule]: convertUiMask NONE");return rildata::NrIconEnum_t::NONE;}} SystemUI显示逻辑
private static MobileIconGroup getNrIconGroup(int nrIconType , int phoneId) {MobileIconGroup iconGroup = TelephonyIcons.UNKNOWN;switch (nrIconType){case NrIconType.TYPE_5G_BASIC:iconGroup = TelephonyIcons.FIVE_G_BASIC;break;case NrIconType.TYPE_5G_UWB:iconGroup = TelephonyIcons.FIVE_G_UWB;break;}return iconGroup;}当QM上报UWB时表示为大带宽，显示5g+
