Embodiment Construction

[0034] The invention provides a wireless data terminal firmware upgrade method, which adds the firmware upgrade device of the invention to the traditional wireless data terminal software structure, and the device includes a download module and an upgrade agent module. Wherein, the download module further includes a download communication sub-module and a download protocol processing sub-module connected to each other. The download communication sub-module is used to communicate with the PC side software for two-way download signaling and data transmission; the download protocol processing sub-module is used to interact with the PC side download signaling to ensure the safety and reliability of the entire download process. The upgrade agent module is used to write the downloaded new version software (generally a differential package) into the FLASH area that needs to be upgraded according to the blocks. After all the blocks are written, the entire firmware upgrade is completed. ...

Abstract

The invention discloses a firmware upgrade method and a device for a wireless data terminal. The method comprises the following steps: a. network equipment of a network side which preserves the information of the wireless data terminal determines that when the wireless data terminal needs an upgrade, PC side software is notified by the terminal; and the PC side software downloads a firmware upgrade edition upgrade pack of the terminal from the network equipment to a PC computer of the terminal, and notifies the terminal; and b. after receiving a notice, the terminal firstly downloads the upgrade pack to a free position of a memory of the terminal, and then causes the downloaded upgrade pack to be written to a predetermind address of the memory, thereby completing firmware upgrade which is carried out from the air. The invention also correspondingly provides the firmware upgrade device for the wireless data terminal. The invention greatly reduces the maintenance cost of a product after sale of a terminal manufacturer, and enhances the user satisfaction degree.

Description

technical field [0001] The invention relates to the field of wireless data terminals, in particular to a firmware upgrading device and method for a wireless data terminal. Background technique [0002] Wireless data terminal refers to data communication terminal equipment with wireless access technology, such as USBmodem, PCMCIA network card and other equipment, such equipment is generally used in conjunction with personal computers, through the software on the computer to achieve high-speed wireless data services, browse the web, send Short message, voice call and other functions. [0003] As the functions that wireless data terminals can provide become more and more complex, the probability of terminal defects and thus the risk of being recalled by manufacturers increases. At present, for wireless data terminals, once an upgrade program is needed to solve a fault, generally the end user can only go to the after-sales maintenance network to update the firmware. [0004] T...
