Get Dedicated Radio Bearer Status and Indication

How to get dedicated radio bearer status and indications

Please follow below steps to get dedicated radio bearer status and indication

1. Implement IServingSystemListener listener class

class ServingSystemListener : public telux::data::IServingSystemListener {
public:
ServingSystemListener(SlotId slotId) : slotId_(slotId) {}
void onDrbStatusChanged(telux::data::DrbStatus status) override {
    std::cout << "\n onDrbStatusChanged on SlotId: "
                << static_cast<int>(slotId_) << std::endl;
    switch(status) {
        case telux::data::DrbStatus::ACTIVE:
            std::cout << "Current Drb Status is Active" << std::endl;
            break;
        case telux::data::DrbStatus::DORMANT:
            std::cout << "Current Drb Status is Dormant" << std::endl;
            break;
        case telux::data::DrbStatus::UNKNOWN:
            std::cout << "Current Drb Status is Unknown" << std::endl;
            break;
        default:
            std::cout << "Error: Unexpected Drb Status is reported" << std::endl;
            break;
    }
}

private:
SlotId slotId_;
};

2. Instantiate initialization callback - this is optional

auto initCb = [&](telux::common::ServiceStatus status) {
    subSystemStatus = status;
    subSystemStatusUpdated = true;
    cv_.notify_all();
};

3. Get the DataFactory and data Serving System Manager instance

auto &dataFactory = telux::data::DataFactory::getInstance();
do {
    subSystemStatusUpdated = false;
    std::unique_lock<std::mutex> lck(mtx_);
    dataServingSystemMgr = dataFactory.getServingSystemManager(slotId, initCb);

4. Check if data Serving System manager is ready

    if (dataServingSystemMgr) {
    std::cout << "\n\nInitializing Data Serving System manager subsystem on slot " <<
            slotId << ", Please wait ..." << std::endl;
    cv_.wait(lck, [&]{return subSystemStatusUpdated;});
    subSystemStatus = dataServingSystemMgr->getServiceStatus();
    }
    if (subSystemStatus == telux::common::ServiceStatus::SERVICE_AVAILABLE) {
    std::cout << " *** DATA Serving System is Ready *** " << std::endl;
    break;
    }
    else {
    std::cout << " *** Unable to initialize data Serving System *** " << std::endl;
    }
} while (1);

5. Register for Serving System listener

dataServingSystemMgr->registerListener(dataListener);

6. Get dedicated radio bearer Status

telux::data::DrbStatus drbStatus = dataServingSystemMgr->getDrbStatus();
switch(drbStatus) {
    case telux::data::DrbStatus::ACTIVE:
    std::cout << "Current Drb Status is Active" << std::endl;
    break;
    case telux::data::DrbStatus::DORMANT:
    std::cout << "Current Drb Status is Dormant" << std::endl;
    break;
    case telux::data::DrbStatus::UNKNOWN:
    std::cout << "Current Drb Status is Unknown" << std::endl;
    break;
    default:
    std::cout << "Error: Unexpected Drb Status is reported" << std::endl;
    break;
}

7. Wait for dedicated radio bearer notifications
