In a process of cell handover, a target access network device may determine the core network type of a target cell according to preferred core network type information reported by a terminal device; alternatively, the target access device may determine the core network type of the target cell by information exchange with a core network device. Therefore, smooth cell handover is ensured, and user experience is improved. The method comprises: during a process of handover of a terminal device from a source cell to a target cell, the terminal device sends preferred core network type information for the target cell to a source access network device, wherein the preferred core network type information is reference information for determining the core network type of the target cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for determining core network type during handover process, terminal device, access network device, and core network device","description":"The present invention provides a method for determining a core network type during a handover process, a terminal device, an access network device, and a core network device.
