To activate a connection, ActivateConnection method should be called via D-Bus 
on org.freedesktop.NetworkManager interface. The NM D-Bus API can be found at 
http://projects.gnome.org/NetworkManager/developers/spec-08.html

You can do it e.g.:
#!/bin/bash

SERVICE="org.freedesktop.NetworkManagerSystemSettings"
CONNECTION="/org/freedesktop/NetworkManagerSettings/2"
DEVICE="/org/freedesktop/NetworkManager/Devices/0"

dbus-send --system --print-reply --type=method_call --
dest='org.freedesktop.NetworkManager' \
'/org/freedesktop/NetworkManager' 
org.freedesktop.NetworkManager.ActivateConnection \
string:"$SERVICE" objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/"

or use command line tool nmcli:
nmcli nm con up id "your connection name"
or
nmcli nm con up uuid <connection uuid>

List connections with:
nmcli con list

Note:
org.freedesktop.NetworkManagerSystemSettings service means system connections 
managed by NM itself (and stored via a plugin, e.g. keyfile) ~ "Available to 
all users"
org.freedesktop.NetworkManagerUserSettings service is run by clients (nm-
applet) and is available just while the client is up.
