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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Network handover method, terminal, controller, gateway, and system","description":"A network handover method, a terminal, a controller, a gateway, and a system.
