Abstract
Mobile management in a cellular network utilizes the multipath-transfer control protocol (MP-TCP). A mobile device establishes a first multipath-transfer control protocol (MP-TCP) subflow to a corresponding node using a first internet protocol (IP) address corresponding to the mobile device. At least a portion of the first IP address is uniquely associated with the first coverage area. The mobile device establishes a second MP-TCP subflow using a second IP address corresponding to the mobile device while the mobile device is in an overlapped coverage area including a first portion of the first coverage area and a second portion of a second coverage area. At least a portion of the second IP address is uniquely associated with the second coverage area. The mobile node turns off the first subflow when the mobile node determines it has left the first coverage area.
