I don't think you can make anyone do anything, especially since what you want is for someone to show you affection on their own accord, I mean - if you tell him call me, and then he calls in 5 minutes, it's not really it, right?!
I think there are a few important things that might make you feel better in this situation, the first is understanding that what you want is not so much the calls and so on, but to know for certain that he loves you and think about you throughout the day. Different people have different ways to show their love,maybe he's a very affectionate person but you are missing his keys - maybe a true prof for his love was introducing you to his friends or missing a game to hang out with you.
Another thing is to remember that you like this person, this is why you chose him as a person, liking a person means liking the whole deal - so he doesn't call, OK, what is it that you do like about him? focus on the good sides, not the bad sides.
Also, you don't want him to try and change you, right? a part of being loved is being accepted, if you feel a need to talk to him in the middle of the day, you should be the one making the call.
What else can you do - instead of telling him what you are unhappy about, make him feel good when he is calling and don't take it for granted. Everytime he's calling tell him that you are really glad he did and that it meant a lot to you. I think that hearing that would make anyone call more.
