Abstract
The present invention provides a method of data path switching. Embodiments of the method include transmitting a packet from a node in a communication system during hand off of a mobile node from a source access network to a target access network. The packet includes an end marker that indicates that the packet is the last packet to be transmitted during the hand off over a source link between the mobile node and an anchor node via the source access network during the hand off. Embodiments of the method also include switching, at the node, a transmission data path from the source link to a target link between the mobile node and the anchor node via the target access network following transmission of the packet including the end marker.
