Wireless communication system and a firmware update method of a wireless communication terminal station in the same
First Claim
1. A wireless communication system, comprising:
- a wireless communication base station connected to a backbone network;
a wireless communication terminal station for conducting data communication via a wireless line with the wireless communication base station;
a mobile terminal in which the wireless communication terminal station is installed; and
a download server connected to the backbone network for managing firmware of the wireless communication terminal station, the download server including first firmware information transmitting means for transmitting, when download of firmware is started, firmware information to the wireless communication base station, the wireless communication base station including temporary storage means for temporarily storing in a queue the firmware information transmitted from the download server and second firmware information transmitting means for transmitting the firmware information stored in the temporary storage means to the wireless communication terminal station, the wireless communication terminal station including first and second recording means for recording firmware therein, firmware activating means for activating the firmware recorded in either one of the first and second recording means, and firmware update means for replacing the firmware recorded in either one of the first and second recording means with new firmware and thereby updating the firmware.

Abstract
In a wireless communication system and a firmware update method of a wireless communication terminal station in the system, firmware can be safely downloaded and updated through wireless communication without affecting user'"'"'s ordinary data communication. The CPU executes arithmetic control processing for various types of data. For example, the CPU controls the data conversion achieved by an high-layer interface. Specifically, to send data from the wireless LAN card to the mobile terminal, the CPU controls conversion processing for the high layer. Conversely, when the mobile terminal sends data to the wireless LAN card, the CPU controls the conversion for the low layer. The CPU also reads and executes a firmware program recorded in one of the memories. The CPU refers to the boot information memory and determines from which one of the memories the firmware is to be read. At firmware update, the CPU determines in which one of the memories data is to be written.
