System and method for providing mobile communication network in vehicle

Abstract

The present invention relates to a system and method for providing a mobile communication network in a vehicle. The system comprises a master control module, a wireless network module and a mobile communication module connecting the master control module with the wireless network module, wherein the master module is used to send an instruction to create a link to the mobile communication module; the mobile communication module is used to establish a long connection with a target server after receiving the instruction to create a link, to keep a real-time mobile communication network link with the target server; and the wireless network module is used to establish a wireless local area network link in a vehicle with a mobile terminal according to a local area network link request of the mobile terminal in the vehicle, and to provide a mobile communication network for the mobile terminal by the connection with the mobile communication module. By means of the technical solution of the present invention, choice costs of the master control module may be reduced, and the problem of delay of data communication with the target server due to the fact that the first wake-up time is too long may be avoided.

Description

Technical field [0001] The present invention relates to the field of automobile technology, in particular to a system and method for providing a mobile communication network in a vehicle. Background technique [0002] With the development of information technology, cars are becoming more and more intelligent. The development and promotion of in-vehicle terminals such as the TBOX system can network cars and calculate the best vehicle diversion strategy through the server to relieve traffic pressure. At the same time, it can enable passengers to enjoy network resources and bring a better user experience. [0003] The existing vehicle terminal such as TBOX system has its own WIFI (Wireless-Fidelity, wireless fidelity module) module, which can share the network of vehicle terminal such as TBOX system to multiple mobile terminals in the vehicle. However, it is the WIFI module and MCU (Microcontroller Unit, microprogram controller) is connected. When providing a communication network fo...

AI Technical Summary

Problems solved by technology

[0003] The existing TBOX system and other vehicle-mounted terminals have their own WIFI (Wireless-Fidelity, wireless fidelity module) module, which can share the network of the TBOX system and other vehicle-mounted terminals with multiple mobile terminals in the vehicle. MCU (Microcontroller Unit, microprogram controller) connection, when providing a communication network for mobile terminals, the communication data needs to be relayed through the MCU, which requires a higher selection of the MCU, and generally requires the use of an ARM chip with a higher cost; another On the one hand, it takes a long time to wake up the vehicle-mounted terminal such as the existing TBOX system for the first time, which will cause data delay with the background server (such as the TSP operator server)
