Telephony基础之DataCall业务(问题切分点)

一,注意下发的apn信息是否正确
RIL.setupDataCall(){
   ...
      if (RILJ_LOGD) riljLog(rr.serialString() + "> "
            + requestToString(rr.mRequest) + " " + radioTechnology + " "
            + profile + " " + apn + " " + user + " "
            + password + " " + authType + " " + protocol);

}

apn下发的参数：
1,radioTechnology       网络通信技术
2,profile               DATA_PROFILE_DEFAULT   0
           DATA_PROFILE_TETHERED 1
           DATA_PROFILE_IMS       2
           DATA_PROFILE_FOTA      3
3,apn           apn设置中的apn 参数
4,user           apn设置中的UserName 参数
5,password       apn设置中的password 参数
6,authType       apn设置中的加密方式（PAP，CHAP）
7,protocol       apn设置中的协议参数

例如:
03-13 17:19:12.553 2562 2705 D RILJ    : [4138]> SETUP_DATA_CALL 14 0 spmode.ne.jp   0 IPV4V6 [SUB0]
03-13 17:19:12.409 2562 2705 D RILJ    : [4137]> SETUP_DATA_CALL 14 2 ims   0 IPV4V6 [SUB0]

二,消息返回是否正确
02-21 14:20:02.522 2295 2337 D RILJ : [3823]< SETUP_DATA_CALL DataCallResponse: {version=11 status=0 retry=-1 cid=0 active=2 type=IP ifname=rmnet_data0 mtu=1500 addresses=[10.177.70.193/30] dnses=[119.6.6.6] gateways=[10.177.70.194] pcscf=[]} [SUB0]
返回的消息会在前面注册的回调消息EVENT_SETUP_DATA_CONNECTION_DONE中处理

三,查看当前网络状态是否正常，即查看注网是否正常
ServiceStateTracker.pollStateDoneGsm(){
   ...
        if (DBG) {
            log("Poll ServiceState done: " +
                    " oldSS=[" + mSS + "] newSS=[" + mNewSS + "]" +
                    " oldMaxDataCalls=" + mMaxDataCalls +
                    " mNewMaxDataCalls=" + mNewMaxDataCalls +
                    " oldReasonDataDenied=" + mReasonDataDenied +
                    " mNewReasonDataDenied=" + mNewReasonDataDenied);
        }
}
02-21 14:22:59.180 2295 2295 D SST : Poll ServiceState done: oldSS=[0 0 voice home data home UNICOM UNICOM 46001 UNICOM UNICOM 46001 LTE UMTS CSS not supported -1 -1 RoamInd=-1 DefRoamInd=-1 EmergOnly=false IsDataRoamingFromRegistration=false IsUsingCarrierAggregation=false mRilImsRadioTechnology=0] newSS=[0 0 voice home data home UNICOM UNICOM 46001 UNICOM UNICOM 46001 LTE LTE CSS not supported -1 -1 RoamInd=-1 DefRoamInd=-1 EmergOnly=false IsDataRoamingFromRegistration=false IsUsingCarrierAggregation=false mRilImsRadioTechnology=0] oldMaxDataCalls=20 mNewMaxDataCalls=20 oldReasonDataDenied=-1 mNewReasonDataDenied=-1

四,apn信息是否正确
02-21 14:19:55.556 2295 2295 D QtiGsmDCT: [0]getPreferredApn: X found apnSetting[ApnSettingV3] 3gnet, 6, 46001, 3gnet, , , , , , -1, *, IP, IP, true, 0, 0, 0, false, 0, 0, 0, 0, , , false
