The method comprises: 1) handover trigger: detecting a new access router AR2 by a mobile receiver in the publish/subscribe system; and sending a handover trigger message comprising AR2 identification information from the mobile receiver to a router AR1 currently connected to the mobile receiver; 2) handover preparation: receiving the handover trigger message by the AR1; selecting a branch node of the most recent position before handover as a proxy for the mobile receiver; and forwarding data packets to paths of the mobile receiver before and after handover; and 3) handover execution: handover access router of the mobile receiver to AR2 by the proxy; after the step of handover access router, triggering AR2 and AR1 to update data transfer for the mobile receiver; sending the data packets through the AR2 to the mobile receiver. The present invention has high handover performance, and can reduce handover time delay and data packet loss."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data transmission method for mobile receiver in publish/subscribe system","description":"A method is disclosed providing data transmission for a mobile receiver in a publish/subscribe system.
