In fact just to a google search on "NIOS" and "Remote Update"

Basically you have to worry about 3 things:

1 - Downloading the fpga and NIOS software images to the board via RS232. Obviously you're going to have to write your own software for this (both on PC and NIOS)

2 - Program the fpga and software images into flash. You're using a NIOS so using the CFI flash controller or EPCS controller is your easiest bet.

3 - Triggering a reconfiguration once you have downloaded the image.

Now you haven't stated what your configuration scheme is or what type of flash you are using.
