In the method of this embodiment, the base station LTE eNB is upgraded by using the above method based on the original LTE NB, and the base station LTE eNB can access a 5G core network (5GC) in addition to still accessing a 4G core network (EPC). For example, the conventional dual registration method is that a ue with 5G/4G capability selects either to access 5GC or EPC after selecting a camping base station lte eNB cell. In the method of this embodiment, a ue with 5G/4G capability can be registered in both 5GC and EPC after camping on the lte eNB upgraded by the method of this embodiment, and can perform 5G service and 4G service based on the same radio link between the ue and the lte eNB.
