The application of technical solution proposed through embodiment of this invention can enable PGW to determine whether handover operation on MME side is completed through timing by timer and/or instruction message on MME side; if it is completed, re-initiate session management process of corresponding EPS system, thus enabling PGW to timely re-initiate EPS session management procedure, reducing the time for unnecessary waiting, and avoiding resource waste caused by repeated rejection of EPS session management procedure re-initiated when handover procedure is not completed, so as to improve reconnection efficiency of session management process of EPS system and reduce waste of communication resource."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and device for reinitiating session management process of EPS system","description":"The present invention discloses a method and device for re-initiating EPS session management procedure.
