Abstract
A network handover method, a terminal, a controller, a gateway, and a system. The method includes: when a terminal accesses a first network, converting data including an initial TCP four-tuple into data including a first TCP four-tuple, and sending the data to a gateway; and after handing over from the first network to a second network, converting data including the initial TCP four-tuple into data including a second TCP four-tuple, and sending the data including the second TCP four-tuple to the gateway. This achieves objectives of preventing a connection from being interrupted before and after the network handover, improving use experience, and reducing complexity of a network handover process.
