Embodiment Construction

[0086] In order to solve the deficiencies of the prior art, the embodiment of the present invention proposes a method, device and system for wireless communication module software autonomous over-the-air upgrade.

[0087] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0088] In order to enable the sub-modules in the wireless communication module to have independent upgrade functions, it is necessary to re-plan the data organization of the wireless communication module, such as figure 1 shown, including:

[0089] Step S101: Modify the scatter-loading file, use the "fixed address" attribute to fix the link address of each submodule at a preset address, that is, fix the first address (base address) of each submodule;

[0090] After fixing the first address of each sub-module, in the compiled image file, each sub-module will be linked and programmed to a fixed location. Preferably, free space requ...

Abstract

The invention provides a data organizing method of a wireless communication module: in the wireless communication module, each submodule is linked and programmed to a fixed address in a memorizer with a modifying decentralizing and loading file; in each submodule, an indicating needle which points to a function which is needed to be called by the other submodule in the submodule or to a used global variable is put in an absolute segment; and the segment is linked to a first address of the submodule with the modifying decentralizing and loading file. The wireless communication module which organizes the data with the method starts a general packet radio service function periodically after networking, is connected with a server by the wireless network and is interacted with the server in a signally way so as to realize the automatic upgrade of current each submodule in the wireless communication module without special people on duty and external memory devices and can upgrade any protocol stack submodule or even whole protocol stack soft wares.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device and system for wireless communication module software autonomous air upgrade. Background technique [0002] Currently, most of the GSM (Global System for Mobile Communications, Global System for Mobile Communications) / GPRS (General Packet Radio Service, General Packet Radio Service) modules developed by various manufacturers do not have an upgrade function. Some GSM / GPRS modules with upgrade function are upgraded by adding peripheral devices locally, such as adding communication interfaces, storage devices outside the module, or cooperating with PCs. However, this method needs to upgrade special hardware and software equipment, and requires a special person on duty, and most of the upgrade scope is limited, for example, only scripts can be upgraded, and software sub-modules or the entire protocol stack software cannot be upgraded. When the module is sold as a product, ...
