Abstract
A method for upgrading firmware (F/W) of a wireless communications device is capable of updating F/W at all times through a simple process by transferring, directly and wirelessly, new firmware required for the wireless communications device from a base station. In the F/W upgrade method, a user's identification of the wireless communications device and information required for F/W upgrade are transferred to the corresponding base station, and the current mode of the wireless communications device is converted into an F/W upgrade mode according to whether or not the corresponding base station allows the upgrade, which is determined based on the transferred information. Then, F/W of the wireless communications device is wirelessly upgraded by the corresponding base station.
