Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile broadband devices require a USB drive to be installed for the host to acquire positioning information, which is inconvenient for direct communication with GPS modules.
Innovation Solution
A method and device using a Mobile Broadband Interface Model (MBIM) to enable direct communication between a terminal and a GPS module through an MBIM data channel, allowing the terminal to acquire positioning information without a USB drive by converting query requests and responses into a user-defined data stream format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a USB virtual serial port is used to transmit positioning information from the mobile broadband device to the host, then the positioning function can be implemented, but a USB drive must be installed which causes inconvenience for the host to acquire positioning information
Solution Approach 1:
The patent introduces an MBIM device as an intermediary component between the terminal and GPS module. This MBIM device establishes an MBIM data channel that enables direct communication without requiring USB drive installation, thus resolving the contradiction between reliable positioning function implementation and ease of operation
Solution Approach 2:
The patent replaces the mechanical USB connection system with an MBIM data channel communication system. By substituting the physical USB virtual serial port mechanism with an MBIM-based data channel, the system eliminates the need for drive installation while maintaining positioning functionality
2Reliability
If a USB virtual serial port is used for communication, then positioning information can be transmitted, but the system complexity increases due to drive installation requirements
Solution Approach 1:
The MBIM device serves as a simplified intermediary that replaces the complex USB virtual serial port system. By using the MBIM protocol and data channel, the patent reduces system complexity while maintaining reliable positioning information transmission capability
3Ease of operation
If the terminal directly acquires positioning information from the GPS module using MBIM device, then the convenience is improved, but a new communication protocol (MBIM) needs to be implemented
Solution Approach 1:
The MBIM device is designed with multi-functionality, serving both as a communication interface and a protocol translator. It can establish MBIM data channels while also supporting standard positioning protocols, thereby improving convenience without significantly increasing overall system complexity

AI summary
The present invention provides a positioning information acquisition method, a terminal, and a Mobile Broadband Interface Model MBIM device. The method includes: acquiring, by a terminal, a positioning query request; sending, by the terminal, the positioning query request to an MBIM device through a Mobile Broadband Interface Model MBIM data channel, so that the MBIM device acquires positioning information of the terminal according to the positioning query request; and receiving, by the terminal through the MBIM data channel, the positioning information returned by the MBIM device. According to the positioning information acquisition method in the present invention, a terminal may directly communicate with an MBIM device through an MBIM data channel, and the MBIM device may directly communicate with a GPS module, so as to implement that the terminal performs positioning by using the MBIM device by acquiring positioning information from the GPS module without installing a drive, which is convenient for the terminal to acquire the positioning information.
