Radio logs analysis

 1️⃣ Voice Registration State

The first part of the log indicates the current voice registration status:

5765]< VOICE_REGISTRATION_STATE {.regState = REG_ROAMING, .rat = LTE, .reasonForDenial = NONE, .cellIdentity = {.lte = {.base = {.base = {.mcc = 404, .mnc = 86, .ci = 205418246, .pci = 378, .tac = 54140, .earfcn = 1582}, .operatorNames = {.alphaLong = Vi India, .alphaShort = Vi India}, .bandwidth = 15000}, .additionalPlmns = [], .optionalCsgInfo = {.noinit = {}}, .bands = [3]}}, .registeredPlmn = 40486, .accessTechnologySpecificInfo = {.noinit = {}}} [PHONE1]

Analysis:

regState = REG_ROAMING → The device is in roaming mode while registered on the LTE network.
rat = LTE → The Radio Access Technology (RAT) is LTE.
reasonForDenial = NONE → No denial reason, meaning there are no issues with network registration.
  • Cell Identity Details:
    • MCC = 404, MNC = 86 → The Mobile Country Code (404) and Mobile Network Code (86) correspond to Vi India (Vodafone Idea).
    • ci (Cell ID) = 205418246 → Unique identifier for the LTE cell tower.
    • pci (Physical Cell ID) = 378 → A unique identifier used for handover decisions.
    • tac (Tracking Area Code) = 54140 → Helps in identifying the location area for mobility management.
    • earfcn (EARFCN = 1582) → The frequency channel number used for LTE communication.
    • Bandwidth = 15000 (15 MHz) → The available spectrum bandwidth for this LTE connection.
    • bands = [3] → LTE Band 3 is being used
2️⃣ Data Registration State

        03-01 06:43:20.503 D/SST     ( 3743): [1] handlePollStateResultMessage: PS IWLAN. 
NetworkRegistrationInfo{ domain=PS transportType=WLAN registrationState=NOT_REG_OR_SEARCHING networkRegistrationState=NOT_REG_OR_SEARCHING roamingType=NOT_ROAMING accessNetworkTechnology=UNKNOWN rejectCause=0 emergencyEnabled=false availableServices=[] cellIdentity=null voiceSpecificInfo=null dataSpecificInfo=null nrState=**** rRplmn= isUsingCarrierAggregation=false}
  • Analysis:

    • PS IWLAN (Packet Switched over Wi-Fi LAN) → This means the device is attempting to use Wi-Fi for data services instead of the cellular network.
    • registrationState = NOT_REG_OR_SEARCHING → The device is not currently registered for data services over Wi-Fi.
    • networkRegistrationState = NOT_REG_OR_SEARCHING → No active data network connection is available.
    • accessNetworkTechnology = UNKNOWN → No specific data access technology (LTE, 3G, etc.) is detected.
    • isUsingCarrierAggregation = false → The device is not using LTE Carrier Aggregation for faster speeds.
