A method and apparatus for facilitating handoff for a mobile entity in a wireless communication network is provided ( 100 ). The method comprising obtaining a first internet protocol (IP) address for the mobile entity ( 105 ) when the mobile entity is attached to a first access node, identifying at least one target access node ( 110 ), the target access node being a potential access node for handoff for the mobile entity, sending a trigger message corresponding to the mobile entity to the identified target access node ( 115 ) and acquiring a second IP addresses for the mobile entity at the target access node ( 120 ). The invention also proposes a method for creating a tunnel for facilitating the handoff for a mobile entity from the first access node to the target access node ( 205, 210, 215, 220 ).
