Terminal NV parameter backup recovering method

Abstract

This method includes steps: Step A. Transfer the data pack with NV_ITEM number (NN) to the bottom layer device (BLD). Step B. store the reply data pack sent from BLD into the file. Step C. Read the data pack with NN from the file and transfers it to BLD. Step D. BLD restores NV parameter. This invention can backup and restore any number of NV items, no matter it is the common NV or the special NV. Therefore, depending on different requirement of each project, this invention can backup and restore corresponding standard NV and save many working position, which is needed to execute the NV operation during the re-doing process before. This invention raises the production efficiency and saves lot of manpower cost for the company and the project.

Description

technical field [0001] The invention provides a simple and efficient NV (Nonvolatile) parameter backup method, which can break through the limitation of the traditional NV parameter backup method. Background technique [0002] Currently, there are 1.3 billion digital mobile subscribers worldwide, and this number is expected to double in the next few years. It is predicted that in 2008, the global communication industry will present a huge market of up to 2 billion mobile users. [0003] Global mobile services and applications are growing in three main directions: voice, multimedia and enterprise applications. Mobile data services will have an increasing share in the mobile market. As of September 2003, the number of global mobile data service users reached 100 million, accounting for 7.7% of the world's 1.29 billion mobile users, an increase of 14% compared with the statistics in June 2003. By 2007, the proportion of mobile data services will rise from 10% in 2002 to 30%,...

Problems solved by technology

[0005] The previous method of backing up and restoring NV is only applicable to some common radio frequency NV items, but for some special NVs, such as emergency numbers (ITEM=57) in 3G (WCDMA), and each emergency number corresponds to a specific data package, multiple emergency numbers correspond to multiple data packets with the same ITEM but different specific content,), the previous method cannot be used

[0006] QPST, a tool of Qualcomm, although this tool can also back up NV, save the NV items of the terminal as corresponding *.qcn files, and restore the corresponding *.qcn files to the terminal, but the backed up NV items It will be limited by the QPST tool of Qualcomm, and the backup and restoration of the common NV items added by our company cannot be backed up and restored, and the special NV items added by our company cannot be backed up and restored. In this way, when the production line is reworked, It is necessary to increase the number of stations to operate these ordinary and special NV items added by our company. Increasing the number of stations means that the company will spend more human resources and costs on production
