Problems solved by technology

However, the fixed operator and tariff package when the vehicle leaves the factory restricts the use of new applications by users
For example, some areas only cover the signal of one operator, but the vehicle can only choose another operator, so the user cannot realize the vehicle navigation, which brings inconvenience to the user

Embodiment Construction

[0019] figure 1 A schematic structural diagram of the vehicle communication device of the present invention is shown. As shown in the figure, the vehicle communication device of the present invention has two SIM cards to realize data interaction, one is an external SIM card and the other is a built-in SIM card. The external SIM card is used for exchanging application service data with the Internet, and the external SIM card is pluggable. The built-in SIM card is used to exchange vehicle service data with the background server.

[0020] The vehicle communication device has an external SIM card slot to accommodate the external SIM card. The external SIM card of the present invention not only refers to an ordinary SIM card, but also a USIM card (Universal Subscriber Identity Module, Universal Subscriber Identity Module) with a larger storage capacity.

[0021] Preferably, after the vehicle-mounted communication device is assembled on the vehicle, the external SIM card slot is ...

Abstract

The invention discloses a vehicle-mounted communication device with an external SIM (subscriber identity module) card. The vehicle-mounted communication device is provided with an internal SIM card, the external SIM card and a communication control module. The internal SIM card is used for interacting vehicle service data with a background server. The external SIM card being hot-pluggable is used for interacting application service data with the internet. The communication control module is used for distinguishing service types selected by a user, and when the external SIM card is hot plugged, the communication control module is configured to 1) generate a card change command on the basis of a card changing function selected by the user; 2) be electrically disconnected with the current external SIM card on the basis of the card changing command; 3) detect a card plug signal generated from plugging of a new external SIM card; 4) recover power supply to the new external SIM card on the basis of the card plug signal. The vehicle-mounted communication device with the external SIM card has the advantages that data services are shunted, and two types of data are controlled to interact via the external SIM card and the internal SIM card respectively.

Description

technical field [0001] The present invention relates to automotive electronics. More specifically, it relates to a vehicle communication device with an external SIM card. Background technique [0002] With the continuous development of Internet of Vehicles technology, more and more car manufacturers are assembling vehicle communication devices on vehicles to realize information interaction between vehicles and the Internet or background servers. There are mainly two types of business data initiated by users through the vehicle communication device. One is the application service data interacting with the Internet. The data volume is relatively large, mainly including map navigation, music, pictures, weather conditions and other applications; the other is One is the vehicle service data interacting with the background server, the data volume is relatively small, mainly data and commands related to the vehicle status. In order to realize the communication with the Internet a...
