You are referring to what is called a status match. While some airlines match status with no strings attached, you will usually have to complete a "challenge" to get your status matched. The equivalency of your status would be United Premier Gold. They would most likely offer you the following: Fly 17,500 qualifying flight miles or 22 flight segments within 90 days to earn Premier Gold status for a year. Please review the 2012
Status Match master thread for more information.
