Device and method for upgrading data terminal

摘要

Provided are a device and method for upgrading a data terminal. The device includes a dialing component, a protocol component, a DHCP Dynamic Host Configuration Protocol (DHCP) server component, a router component, an Internet Protocol (IP) processing component, an upgrading component and a web server component, wherein the dialling component implements a dialling flow; and the upgrading component acquires a private IP address from the DHCP server component, sends a request message of detecting whether there is a new version to a version server through the router component and the protocol component, and if there is the new version, downloads the new version from the version server and writes the new version into a flash of a data terminal, and then the data terminal is automatically restarted to finish upgrading. According to the technical solution, an upgrading process of the data terminal under a win8 operating system, a web server access process and a network access process of a Personal Computer (PC) are independently implemented, relevance between the upgrading process of the data terminal and an operating system of the PC is reduced, Microsoft win8 logo authentication can be passed, and a driver-free function may further be realized.

1. A device for upgrading a data terminal, comprising: a router component, and a protocol component, a Dynamic Host Configuration Protocol (DHCP) server component and an upgrading component, which are all coupled with the router component, further comprising a dialling component coupled with the protocol component, wherein the dialling component is configured to initiate and implement a network dialling flow of a data terminal; the upgrading component is configured to negotiate and implement a DHCP procedure with the DHCP server component; the DHCP server component is configured to allocate a private Internet Protocol (IP) address to the upgrading component; the upgrading component is configured to send, through the router component and the protocol component, a request message of detecting whether there is a new version or not to a version server on a network side after the DHCP server successfully allocates the private IP address to the upgrading component, and when there is the new version on the version server, download the new version from the version server and write the new version into a flash of the data terminal, which enables the data terminal to finish upgrading upon automatic restart.
