Method and system for downloading software

Abstract

The present invention provides a method and system for unloading soft-wares. Therein, the method comprises the following procedure: an exclusive mark is added at the position of the beginning of each file in the file system; before a software is unloaded, the exclusive mark of each file in the file system is sought, and the address of the exclusive mark is acquired. The actual address of the required parameter is calculated according to the address of the exclusive mark and the deviation quantity of the parameter in the corresponding file, and the parameter value of the required parameter is acquired. After the parameter value of the required parameter is acquired, whether the parameter value satisfies the requirement is judged, and whether to perform the software unloading is determined according to the judgment result. Therefore, the technology of the present invention has greater commonality, the present invention facilitates the user, the application scope is wide and the present invention is simple and easy.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically, to a method and system for downloading software by a wireless access terminal. Background technique [0002] Wireless access terminals, for example, wireless access fixed stations (hereinafter referred to as fixed stations) using wireless access methods such as CDMA or GSM (Global System for Mobile communications), some parameters of which will be changed according to different Recalculate according to the actual hardware conditions (for example: the voltage-controlled oscillator parameters of the fixed station, that is, VCO parameters (Voltage Control Oscillation), etc.), so the specific values ​​of these parameters must be obtained before the software is downloaded, and judged according to the actual values Whether the download conditions are met. For example, the VCO parameter, when the software is downloaded for the first time, if the value of th...

Problems solved by technology

The VCO and other parameters are stored in the memory in the form of a file system, but because the physical address of the file system usually changes each time it runs, it is impossible to know the actual physical address of the VCO and other parameters when they are stored.

In the prior art, the solution to this problem is that the physical address of the file system remains unchanged each time it is constructed (as shown in Figure 1). The disadvantage of this method is that when a file is deleted, the file occupies The address can no longer be used, resulting in a serious waste of physical space, which cannot be allowed on embedded devices such as wireless terminals where storage space is very precious
