## Abstract

A method of automatically switching a mode of receiving differential data for driving test and driver training using a mobile station includes the following steps of: after a mobile station installed on a training vehicle is powered on, using a mode of receiving the differential data by a radio station; if the differential data cannot be received within a preset time period under the mode, switching the radio station to a GPRS mode; if the radio station of the mobile station receives failure information, feeding the information back to a back-end server by the mobile station; informing a technician, by the back-end server, to perform troubleshooting, after the radio station failure is eliminated, feeding information back to the mobile station through the back-end server, and switching the mobile station back to the mode of receiving the differential data by the radio station.

## Claims

### Claim 1

A method of automatically switching a mode of receiving differential data for a driving test and driver training using a mobile station comprising:
installing a mobile station on a training vehicle;
after the mobile station is powered on, using a mode of receiving the differential data by a radio station;
if the radio station of the mobile station is unable to receive the differential data within a preset time period under the mode, switching the radio station to a General Packet Radio Service (GPRS) mode and receiving the differential data through a wireless network;
if the radio station of the mobile station receives radio station failure information, feeding the radio station failure information back to a back-end server by the mobile station;
informing a technician, by the back-end server, to perform troubleshooting, after the radio station failure is eliminated;
feeding information of an elimination of the radio station failure back to the mobile station through the back-end server; and
switching the mobile station back to the mode of receiving the differential data by the radio station; wherein after the radio station is switched to the GPRS mode, a Transmission Control Protocol (TCP) connection is established and a Cross-origin resource sharing (CORS) account is logged in, and the differential data is received through the wireless network.

### Claim 2

A method of automatically switching a mode of receiving differential data for a driving test and driver training using a mobile station comprising:
installing a mobile station on a training vehicle;
after the mobile station is powered on, using a mode of receiving the differential data by a radio station;
if the radio station of the mobile station is unable to receive the differential data within a preset time period under the mode, switching the radio station to a General Packet Radio Service (GPRS) mode and receiving the differential data through a wireless network;
if the radio station of the mobile station receives radio station failure information, feeding the radio station failure information back to a back-end server by the mobile station;
informing a technician, by the back-end server, to perform troubleshooting, after the radio station failure is eliminated;
feeding information of an elimination of the radio station failure back to the mobile station through the back-end server; and
switching the mobile station back to the mode of receiving the differential data by the radio station; wherein the mobile station feeds back the radio station failure information to the back-end server through one of GSM, 3G or 4G network.
