Wireless software upgrades with version control

Abstract

A wireless communication system includes a system backbone, a host computer coupled to the system backbone, at least one base station coupled to the system backbone, the at least one base station including a base station transceiver for communicating wirelessly with mobile devices within the system, and at least one mobile device having a mobile device transceiver for communicating wirelessly with the host computer on the system backbone via the at least one base station. A method of operation includes the steps determining whether a version of operating software stored in the at least one mobile device is a current version of the operating software, and wirelessly updating the operating software stored in the at least one mobile device if it is determined that the operating software stored in the at least one mobile device is not the current version.

Benefits of technology

[0012] Furthermore, the system and method of the present invention also allows a user to select one or more different packages of operating software which may be available from the FTP server. A user may simply select a package of operating software from a menu provided by the mobile device, and in response the mobile device prompts the FTP server to download the selected package to the mobile device. According to another feature of the invention, a WAN includes a plurality of communication systems tied together by a WAN based system backbone. A WAN based host computer provides updated information regarding the most current operating software available via the FTP server to all other host computers in the individual systems. A WAN based FTP server provides updated mobile terminal operating software to the FTP server in the individual systems. The mobile device operating software can then be distributed quickly to the various mobile devices.

Problems solved by technology

Due to changing market needs and advancements in technology, for example, it often happens that the software which is preloaded into a mobile device becomes outdated prior to the time the mobile hardware device becomes obsolete.

This results in down time for the mobile device and related service costs.

Unfortunately, the periodic transfer of upgraded operating software to the mobile device can be extremely time consuming and becomes increasingly more time consuming as the number of mobile devices within the system increases.

Furthermore, since there is no way to determine if software has been changed since the previous time the mobile device software has been upgraded, time is frequently wasted updating the mobile device operating software with the same version of software which already exists in the mobile device.
