Since you are already using /etc/network/interfaces take a look at 

man ifup



Especially see "ifup eth0=home"

On my laptop, the analogue is 

ifup eth1=home

because the wireless interface is eth1.


The next suggestion I have *not* tested, but it is also in 

man ifup

       -i FILE, --interfaces=FILE
              Read  interface  definitions from FILE instead of from /etc/net-
              work/interfaces.

If this means what it seems to mean, you can write a different file
for each of your configurations, and start ifup with the i option.

ifup is part of the package (in stable) ifupdown.

See also man ifdown.
