Abstract
A method and apparatus for handling mobility for a first host with a MPTCP connection to a second host. The first host is identified by a master address that does not change for the duration of the connection, and a plurality of locators. Each locator is associated with a path used in the MPTCP connection. The first host then determines that it has moved, and so obtains new locators. It then sends a first message to a Location Server (LS). The LS maintains an association between the master address and the locators, and the first message includes the new locators. The first host then sends a second message to the second host, the second message including the new locators. The first host can then receive packets sent from the second host sent using the MPTCP connection using the new locators.
