Abstract

A method of operating a vehicle terminal mounted on a connected car includes receiving, from a remote server, a vehicle state check request for changing a mobile network operator (MNO) which provides a communication network to be connected via a communication modem, checking a vehicle state according to the vehicle state check request and transmitting a vehicle state result determined based on the checked vehicle state to the remote server, receiving a request to change a subscriber profile of a first MNO set to the communication modem for a subscriber profile of a second MNO when the vehicle state result indicates that a subscriber profile update is possible, changing the communication modem with the subscriber profile of the second MNO, and accessing a communication network of the second MNO, and receiving a connected car service from the remote server via the communication network of the second MNO.

First claim

What is claimed is:

1. A method of operating a vehicle terminal mounted on a connected car, the method comprising:
receiving, from a remote server, a vehicle state check request for changing a mobile network operator (MNO) that provides a communication network to be connected via a communication modem;
checking a vehicle state according to the vehicle state check request and transmitting a vehicle state result determined based on the checked vehicle state to the remote server;
in response to the vehicle state result indicating that a subscriber profile update is possible, receiving a request to change a subscriber profile of a first MNO set to the communication modem for a subscriber profile of a second MNO;
changing the communication modem with the subscriber profile of the second MNO, and accessing a communication network of the second MNO; and
receiving a connected car service from the remote server via the communication network of the second MNO.

2. The method of claim 1 , wherein the checked vehicle state comprises at least one of a startup state of the connected car, whether the communication modem is available for communication connection, whether there is a software update in progress or scheduled software update, or a battery state of the connected car.

3. The method of claim 1 , wherein the vehicle state result comprises information indicating whether a subscriber profile update is possible or impossible.

4. The method of claim 1 , wherein receiving the vehicle state check request comprises transmitting a communication failure report message to the remote server in response to a communication failure occurring during being connected to a communication network of the first MNO, and then receiving the vehicle state check request from the remote server.

5. The method of claim 4 , wherein the communication failure report message is transmitted as a short message.

6. The method of claim 1 , wherein receiving the vehicle state check request comprises:
transmitting, to a user terminal, a communication failure notification message requesting to report a communication failure to the remote server in response to the communication failure occurring during being connected to a communication network of the first MNO; and
then receiving the vehicle state check request from the remote server.

7. The method of claim 1 , wherein receiving the request to change the subscriber profile of the second MNO comprises:
receiving, from a system of the first MNO, a request to replace with the subscriber profile of the second MNO, wherein the system of the first MNO receives a request to change the subscriber profile from the remote server.

8. The method of claim 1 , wherein receiving the connected car service comprises:
synchronizing changed communication information with the remote server to receive the connected car service.

9. A method of operating a remote server communicating with a vehicle terminal mounted on a connected car, the method comprising:
upon receiving a communication failure report message from the vehicle terminal, checking whether a communication failure occurred based on the communication failure report message, and determining whether to change a first mobile network operator (MNO) that provides a communication service to the vehicle terminal;
requesting a vehicle state check for an MNO change to the vehicle terminal, and receiving a vehicle state result determined based on a vehicle state; and
in response to the vehicle state result indicating that a subscriber profile update is possible, requesting a system of the first MNO to change a subscriber profile of the vehicle terminal for a subscriber profile of a second MNO.

10. The method of claim 9 , further comprising:
receiving a notification of an access of the vehicle terminal from a system of the second MNO; and
providing a connected car service after synchronizing changed communication information with the vehicle terminal.

11. The method of claim 9 , wherein the vehicle state comprises at least one of a startup state of the connected car, whether a communication modem is available for communication connection, whether there is a software update in progress or scheduled software update, or a battery state of the connected car.

12. A vehicle terminal mounted on a connected car, the vehicle terminal comprising:
a communication modem;
a non-transitory memory storage comprising instructions; and
a processor in communication with the communication modem and the memory storage, wherein the processor is configured to execute the instructions to:
receive, from a remote server, a vehicle state check request for changing a mobile network operator (MNO) that provides a communication network to be connected via the communication modem;
check a vehicle state according to the vehicle state check request and transmitting a vehicle state result determined based on the checked vehicle state to the remote server;
in response to the vehicle state result indicating that a subscriber profile update is possible, receive a request to change a subscriber profile of a first MNO set to the communication modem for a subscriber profile of a second MNO;
change the communication modem with the subscriber profile of the second MNO, and access a communication network of the second MNO; and
receive a connected car service from the remote server via the communication network of the second MNO.

13. The vehicle terminal of claim 12 , wherein the communication modem comprises an embedded universal integrated circuit card.

14. The vehicle terminal of claim 12 , wherein the checked vehicle state comprises at least one of a startup state of the connected car, whether the communication modem is available for communication connection, whether there is a software update in progress or scheduled software update, or a battery state of the connected car.

15. The vehicle terminal of claim 12 , wherein the vehicle state result comprises information indicating whether a subscriber profile update is possible or impossible.

16. The vehicle terminal of claim 12 , wherein the instructions to receive the vehicle state check request comprise instructions to transmit a communication failure report message to the remote server in response to a communication failure occurring during being connected to a communication network of the first MNO, and receive the vehicle state check request from the remote server.

17. The vehicle terminal of claim 12 , wherein the instructions to receive the vehicle state check request comprise instructions to:
transmit, to a user terminal, a communication failure notification message requesting to report a communication failure to the remote server in response to the communication failure occurring during being connected to a communication network of the first MNO; and
receive the vehicle state check request from the remote server.
