Embodiment 1

[0052] In order to adapt to the driving and data access of high-speed mobile broadband devices, this embodiment provides a general mobile broadband device driving method and device on the Android system, which can improve the communication speed between the mobile broadband device and the device driver, and is compatible with The existing board-side NDIS solution reduces the difficulty and workload of board-side development, thereby reducing development costs.

[0053] The driving method and system based on the Android system in this embodiment are a new optimized and normalized driving method and device. Figure 5 It is a schematic diagram of the driving device of the Android system mobile broadband device according to the first embodiment of the present invention, such as Figure 5 shown, removed figure 1 Among them, the PPP module 12 abandons the Modem port and the PPP protocol, and uses the NDIS port and the QMI protocol with better performance instead, and handles the re...

Embodiment 2

[0058] This embodiment provides a general device driving method and system on the Android system. During implementation, the dialing method using the Modem+PPP protocol is abandoned, and the “NDIS+QMI” protocol method is used instead; The existing USB CDC-ECM driver on the Android system enables the Android system to support NDIS devices; and on the basis of the existing RIL driver, the support of the QMI protocol is added, so that data, configuration, SMS, phone book and other services can be based on the type of service. Different protocols use different protocols (AT, QMI). Among them, the QMI protocol can adopt an asynchronous mode; in terms of implementation, the interface of the QMI protocol to the upper layer can be integrated into the existing RIL framework of the Android system, without modifying the architecture of the RIL and Framework of the Android system, which can increase the Android system's interface. Extensibility.

Embodiment 3

[0068] This embodiment is a method for processing downlink data flow in service implementation, Image 6 is a schematic diagram of a downstream data flow according to Embodiment 3 of the present invention, such as Image 6 As shown, the method includes the following steps:

[0069] Step S602, the RIL layer receives various function calls of the Android system.

[0070] Step S604, calling different processing procedures according to different service types; if it is a data service or a configuration service, go to step S606; if it is a short message, phone book and other services, go to step S608.

[0071] Step S606, if it is a data service, configuration and other services, enter the processing flow of the QMI instruction, and go to step S610.

[0072] Step S608, if it is a service such as a short message, a phone book, etc., enter the processing flow of the AT command, and go to step S610.

[0073] Step S610, determine whether the current QMI command is supported, if yes, ...

Abstract

The invention discloses a data processing method of a mobile broadband device and a drive device. The method comprises the following steps: receiving a function calling request of an Android system from an RIL (radio interface layer) layer; and packaging the function calling request into a corresponding QMI (qualification management interface) instruction by a QMI defense process through a QMI protocol interface registered in an RIL library when the function calling request belongs to data business and configuration business, and sending the packaged QMI instruction into an NDIS (network driver interface standard) device. The scope of applications of the Android system is enlarged, and the performance of the system is improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular, to a data processing method and a driving device of a mobile broadband device. Background technique [0002] With the evolution of technology and the popularization of mobile broadband, the mobile Internet has provided people with a wealth of home entertainment, business office and other services; based on The Third Generation Mobile Communications (3G for short) and the fourth generation mobile The expansion of communications (The Fourth Generation Mobile Communications, referred to as 4G for short) business and the development of more and more Internet applications make the pursuit of mobile broadband speed one of the main goals. Based on the global wireless chip pattern, the Network Driver Interface Specification (NDIS) + QMI (Qualcomm MSM Interface) high-speed access solution for mobile broadband devices promoted by Qualcomm and Microsoft has become the mainstr...
