After mobile terminal sends the data of unstructured supplementary data traffic USSD to network operator server, network
The USSD that carrier server can be returned to mobile terminal returns to message, wherein the Modem layer of system can receive the USSD at first
Message is returned, but Modem layers of processing is more complicated, does not handle message usually, but directly report, therefore RIL
Layer, ccf layer and application layer can theoretically obtain the USSD return message for being received back the network operator server come, but
It is since RIL layers are one layers with Modem layers of direct communication, it is contemplated that report and need the time, be directly most square in RIL layers of processing
Just with it is the fastest.Therefore, the USSD that the network operator server feedback for being received back can be preferably obtained at RIL layers is returned
Message and the processing that it is followed the steps below.
Step S103, judge that the USSD returns to whether message is because of the failure that network cause causes data to send failure
Information；
Wherein, it may include that data send success message and data that the USSD that network operator server returns, which returns to message,
Send failed message.When mobile terminal transmits message to network operator server, network sometimes will appear network busy
Or situations such as unknown error, causes USSD data to send failure, and the number for being included in message is returned according to the USSD fed back
It is believed that breath (such as: error code or other identification informations) can determine whether because network cause causes data to send failure, if because
Cause data to send failure for network cause, thens follow the steps S104.
Step S104, that cancels default returns to USSD information reporting to the mechanism of systematic difference layer, again to network
