That is, if we start the phonesim, it will simulate some tty ports under /dev and udevd will inform the oFono there is a new device (We need some rule for phonesim). And the device disappears if phonesim meets an end.

in theory yes, but phonesim is the one piece that also works via TCP. So
just having a /etc/ofono/phonesim.conf is a lot simpler.
