But already user registered  with mobile number .. again come with fb for  logins.. How to Check If That user is already registered are not ...? in this condition i treat like a  user registered with mobile number and facebook treat like a single user

The simplest solution for me would be to store the value if a user has registered by a mobile phone number in a session/cookie, which doesn't get destroyed for a very long time. Then after the FB login you can check if this value exists. If true: bind mobilephone + fb login else create new Account or whatever.

I hope I could help you
