A method for handing off a connection of a mobile device from a first access point to a second access point in an Internet Protocol-based multimedia mobile network includes the steps of scanning the network for available access points, comparing a connection strength of each available access point to a pre-determined margin, authenticating access points determined to be above the pre-determined margin, adding the authenticated access points to an association table; checking a connection strength to the first access point to the pre-determined margin, selecting an authenticated access point as the second access point if the connection strength to the first access point is below the pre-determined margin, and removing the first access point from the association table.
