Methods for determining the type of core network during the handover process, terminal equipment, access network equipment and core network equipment

摘要

The present application provides a method for determining the type of core network during the handover process, a terminal device, an access network device and a core network device, and in the cell handover process, the target access network device is reported by the terminal device. The preferred core network type information can determine the type of core network in the target cell, or the target access network device can determine the type of core network in the target cell by information interaction with the core network device. This ensures smooth execution of cell handover and improves the user experience. The method is that during the process of handing over the terminal device from the source cell to the target cell, the terminal device transmits preferred core network type information for the target cell to the source access network device, wherein the preferred core. Includes that the network type information is reference information for determining the type of core network of the target cell.
