Method for parameter keeping after software upgrade of wireless access fixing station

2006 
The invention discloses a method for maintaining parameters of updated wireless accessed fixed station software includes the following steps: dividing a memory area into a first part and a second part in which the second part is used as a cache for backup parameters; copying the parameters from the first part to the second part when a download command is received, and storing the electric serial number in the second part; updating the soft ware by cleaning memory in the first part and maintaining memory in the second part; restarting after the software is updated, and recovering the parameters from the second part to the first part. By arranging the second part and using the second part as a cache, the invention solves the problem of lost of parameters (ESN,AKEY,SSD_A,SSD_B) after the software is updated. Thus, the second part can be used as a safe and reliable parameters transferring station during update of the software, which ensures no change of the parameters after the software is updated and exhibits convenience during application by users.
