This paper proposes a user terminal-controlled mobility management across heterogeneous networks without architectural changes in existing infrastructure. It describes a user-centric approach for vertical handover management. The user-centric network selection at the terminal supports seamless terminal-initiated and terminal-controlled vertical handover. It enables the mobile terminals to select the most suitable access network .Existing handoff methods are disconnection oriented, if the signal strength is considerably low then hand off is initiated. These kinds of handoff don't take any other factors into account. The proposed method handles handoff in a user preferred way. Whenever user want the terminal can force a handoff. It provides the user a way to get connected to the preferred network or service.
