AT指令,暂未发现发送AT请求的frameworks接口,通过打印信息总结AT指令: AT+EIMSVOICE: Enable/Disable IMS Voice Capability
+EIMSVOICE=
: integer
0 disable IMS Voice capability
1 enable IMS Voice capability
note:This command should set from AP side while boot-up;
At runtime, AP side could set the command anytime, and IMS module will apply the setting for next round of IMS registration;
而后有如下打印信息,发送RIL_REQUEST_SET_IMS_ENABLE请求:
此发送接口在ImsService.java 类中的onRequestImsSwitch(): public void onRequestImsSwitch(int simIdx, boolean isImsOn) {
int phoneId = getMainCapabilityPhoneId();
if (DBG) {
Rlog.d(LOG_TAG,"onRequestImsSwitch simIdx=" + simIdx +
" isImsOn=" + isImsOn + " mainCapability id=" + phoneId);
}
if (mActivePhoneId != phoneId) {
mActivePhoneId = phoneId;
}
if (isImsOn) {
if (mImsState != PhoneConstants.IMS_STATE_ENABLE) { //如果是关闭状态
mImsRILAdapter.turnOnIms(mHandler.obtainMessage(EVENT_SET_IMS_ENABLED_DONE));
mImsState = PhoneConstants.IMS_STATE_ENABLING;
} else {
Rlog.d(LOG_TAG, "Ims already enable and ignore to send AT command.");
}
}
ImsRILAdapter类封装消息请求,通过send()发送RIL接收端;
ImsIntentReceiver广播接收器,根据log打印信息: 在PhoneBase类中定义了mImsIntentReceiver广播接收器: private BroadcastReceiver mImsIntentReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Rlog.d(LOG_TAG, "mImsIntentReceiver: action " + intent.getAction());
if (intent.hasExtra(ImsManager.EXTRA_PHONE_ID)) {
int extraPhoneId = intent.getIntExtra(ImsManager.EXTRA_PHONE_ID,
SubscriptionManager.INVALID_PHONE_INDEX);
Rlog.d(LOG_TAG, "mImsIntentReceiver: extraPhoneId = " + extraPhoneId);
if (extraPhoneId == SubscriptionManager.INVALID_PHONE_INDEX ||
extraPhoneId != getPhoneId()) {
return;
}
}
synchronized (PhoneProxy.lockForRadioTechnologyChange) {
//接收广播ACTION_IMS_SERVICE_UP
if (intent.getAction().equals(ImsManager.ACTION_IMS_SERVICE_UP)) {
......
mImsServiceReady = true;
updateImsPhone();
ImsManager.updateImsServiceConfig(mContext, mPhoneId, false);
//接收广播ACTION_IMS_SERVICE_DOWN
} else if (intent.getAction().equals(ImsManager.ACTION_IMS_SERVICE_DOWN)) {
mImsServiceReady = false;
updateImsPhone();
}
}
}
};
updateImsPhone()方法如下: protected void updateImsPhone() {
Rlog.d(LOG_TAG, "updateImsPhone"
+ " mImsServiceReady=" + mImsServiceReady);
if (mImsServiceReady && (mImsPhone == null)) {
//创建mImsPhone notifyDataRegStateRilRadioTechnologyChanged
mImsPhone = PhoneFactory.makeImsPhone(mNotifier, this);
CallManager.getInstance().registerPhone(mImsPhone); //CallManager里添加Phone对象
mImsPhone.registerForSilentRedial(
this, EVENT_INITIATE_SILENT_REDIAL, null); //注册消息,该消息的处理由该类处理
} else if (!mImsServiceReady && (mImsPhone != null)) {
CallManager.getInstance().unregisterPhone(mImsPhone);
mImsPhone.unregisterForSilentRedial(this);
mImsPhone.dispose();
// Potential GC issue if someone keeps a reference to ImsPhone.
// However: this change will make sure that such a reference does
// not access functions through NULL pointer.
//mImsPhone.removeReferences();
mImsPhone = null;
}
EVENT_INITIATE_SILENT_REDIAL 消息的处理:
case EVENT_INITIATE_SILENT_REDIAL:
Rlog.d(LOG_TAG, "Event EVENT_INITIATE_SILENT_REDIAL Received");
ar = (AsyncResult) msg.obj;
if ((ar.exception == null) && (ar.result != null)) {
String dialString = (String) ar.result;
if (TextUtils.isEmpty(dialString)) return;
try {
dialInternal(dialString, null, VideoProfile.STATE_AUDIO_ONLY, null);
} catch (CallStateException e) {
Rlog.e(LOG_TAG, "silent redial failed: " + e);
}
}
break;
ServiceState服务状态,有如下打印信息: vendor/mediatek/proprietary/frameworks/opt/tedongle/src/java/android/tedongle/ServiceState.java private void setNullState(int state) {
if (DBG) Rlog.d(LOG_TAG, "[ServiceState] setNullState=" + state);
mVoiceRegState = state;
mDataRegState = state;
mVoiceRoamingType = ROAMING_TYPE_NOT_ROAMING;
mDataRoamingType = ROAMING_TYPE_NOT_ROAMING;
.......
}
setNullState()该方法传入的参数是3,可判定被该方法调用: public void setStateOff() {
setNullState(STATE_POWER_OFF);
}
ServiceState 的定义: /**
* Normal operation condition, the phone is registered
* with an operator either in home network or in roaming.
*/
public static final int STATE_IN_SERVICE = 0;
/**
* Phone is not registered with any operator, the phone
* can be currently searching a new operator to register to, or not
* searching to registration at all, or registration is denied, or radio
* signal is not available.
*/
public static final int STATE_OUT_OF_SERVICE = 1;
/**
* The phone is registered and locked. Only emergency numbers are allowed. {@more}
*/
public static final int STATE_EMERGENCY_ONLY = 2;
/**
* Radio of telephony is explicitly powered off.
*/
public static final int STATE_POWER_OFF = 3;
注册消息: private void registerIndicationReceiver() {
if (DBG) log("registerIndicationReceiver");
IntentFilter intentfilter = new IntentFilter();
intentfilter.addAction(ImsManager.ACTION_IMS_INCOMING_CALL_INDICATION);//注册来电通知
mPhone.getContext().registerReceiver(mIndicationReceiver, intentfilter);
}
notifyDataRegStateRilRadioTechnologyChanged: 在GsmServiceStateTracker类的pollStateDone()方法中,调用notifyDataRegStateRilRadioTechnologyChanged(): if (hasDataRegStateChanged || hasRilDataRadioTechnologyChanged) {
notifyDataRegStateRilRadioTechnologyChanged();
//WLAN 判断
if (ServiceState.RIL_RADIO_TECHNOLOGY_IWLAN
== mSS.getRilDataRadioTechnology()) {
mPhone.notifyDataConnection(Phone.REASON_IWLAN_AVAILABLE);
} else {
mPhone.notifyDataConnection(null);
}
}
protected void notifyDataRegStateRilRadioTechnologyChanged() {
int rat = mSS.getRilDataRadioTechnology();
int drs = mSS.getDataRegState();
if (DBG) log("notifyDataRegStateRilRadioTechnologyChanged: drs=" + drs + " rat=" + rat);
//设置TelephonyProperties.PROPERTY_DATA_NETWORK_TYPE属性
mPhoneBase.setSystemProperty(TelephonyProperties.PROPERTY_DATA_NETWORK_TYPE,
ServiceState.rilRadioTechnologyToString(rat));
mDataRegStateOrRatChangedRegistrants.notifyResult(new Pair<Integer, Integer>(drs, rat));
}
mDataRegStateOrRatChangedRegistrants通知者注册函数: public void registerForDataRegStateOrRatChanged(Handler h, int what, Object obj) {
Registrant r = new Registrant(h, what, obj);
mDataRegStateOrRatChangedRegistrants.add(r); //添加监听者
notifyDataRegStateRilRadioTechnologyChanged();
}
该注册函数在ImsPhone的构造函数中被调用: ImsPhone(Context context, PhoneNotifier notifier, Phone defaultPhone) {
mDefaultPhone = (PhoneBase) defaultPhone;
/// M: ALPS02759855. ImsPhoneCallTracker may change service state earlier. @{
// mCT = new ImsPhoneCallTracker(this);
// mSS.setStateOff();
mSS.setStateOff(); //此处即在"ServiceState服务状态"中提到的
mCT = new ImsPhoneCallTracker(this);
/// @}
mPhoneId = mDefaultPhone.getPhoneId();
// This is needed to handle phone process crashes
// Same property is used for both CDMA & IMS phone.
mIsPhoneInEcmState = SystemProperties.getBoolean(
TelephonyProperties.PROPERTY_INECM_MODE, false);
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, LOG_TAG);
mWakeLock.setReferenceCounted(false);
if (mDefaultPhone.getServiceStateTracker() != null) {
mDefaultPhone.getServiceStateTracker()
.registerForDataRegStateOrRatChanged(this,
EVENT_DEFAULT_PHONE_DATA_STATE_CHANGED, null); //注册数据状态变化通知消息
}
updateDataServiceState();
}
EVENT_DATA_CONNECTION_DRS_OR_RAT_CHANGED消息的处理 在DataConnection.java中处理: case EVENT_DATA_CONNECTION_DRS_OR_RAT_CHANGED:
ar = (AsyncResult) msg.obj;
Pair<Integer, Integer> drsRatPair = (Pair<Integer, Integer>) ar.result;
mDataRegState = drsRatPair.first;
if (mRilRat != drsRatPair.second) {
updateTcpBufferSizes(drsRatPair.second);
}
mRilRat = drsRatPair.second;
if (DBG) {
log("DcDefaultState: EVENT_DATA_CONNECTION_DRS_OR_RAT_CHANGED"
+ " drs=" + mDataRegState
+ " mRilRat=" + mRilRat);
}
ServiceState ss = mPhone.getServiceState(); //实例化ServiceState
// M: [C2K][IRAT] Get network type from IRAT controller
// TODO: check if the message is handled before
// IratController update its current RAT.
if (CdmaFeatureOptionUtils.isCdmaLteDcSupport()) {
//can get networkType from svltePhoneProxy to get right network type
ServiceState svlteSs = SvlteUtils.getSvltePhoneProxy(mPhone.getPhoneId())
.getSvlteServiceState();
if (svlteSs != null) {
ss = svlteSs;
}
}
int networkType = ss.getDataNetworkType();
mNetworkInfo.setSubtype(networkType,
TelephonyManager.getNetworkTypeName(networkType));
if (mNetworkAgent != null) {
updateNetworkInfoSuspendState();
mNetworkAgent.sendNetworkCapabilities(makeNetworkCapabilities());
mNetworkAgent.sendNetworkInfo(mNetworkInfo);
mNetworkAgent.sendLinkProperties(mLinkProperties);
}
break;
设置网络参数 public void setDataRegState(int state) {
mDataRegState = state;
if (DBG) Rlog.d(LOG_TAG, "[ServiceState] setDataRegState=" + mDataRegState);
}
public void setRilDataRadioTechnology(int rt) {
this.mRilDataRadioTechnology = rt;
if (DBG) Rlog.d(LOG_TAG, "[ServiceState] setDataRadioTechnology=" + mRilDataRadioTechnology);
}
