Guard drill

What do I do if I go into labor while my boy friend is at drill and I can't get ahold of him? I'm due January 4th and his drill is 2.5 hours aways from home. I'm really worried I won't be able to get ahold of him right away and the roads will be shitty and he will miss the delivery. Also is there a certain point when I should call him I don't really want to wait until I'm in full blown active labor since it will take so long for him to get home but I also don't want to call and it be a false alarm.
