After establishing a first network connection, the electronic device enters a power-saving state from an operation state. While operating in the power-saving state, a communication module of the electronic device continuously detects a keep-alive packet transmitted by the server via the first network connection. If an error of reception of the keep-alive packet occurs, the electronic device returns to the operation state from the power-saving state in response to a wake-up signal, so as to re-establish a second network connection between the electronic device and the server."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for keeping remote connection, electronic device and server","description":"A method for keeping remote connection, an electronic device, and a server are provided.
