Abstract
A method includes connecting, by a terminal device, in a protocol data unit session establishment procedure, to at least one master node and at least one network node that provides a proxy for at least one connection of the terminal device, and establishing a master multipath transmission control protocol sub-flow. The method includes receiving, at a multipath transmission control layer, a notification that includes at least one multipath transmission control segment with an add address option that advertises an internet protocol interface address of at least one of the proxy and the at least one network node, and establishing a secondary multipath transmission control protocol sub-flow to the internet protocol interface address in response to receiving the notification.
