migrate from the first network to the second network the processor 92 migrates to the second network that does not exist in the migration prohibited list which can further optimize resource configuration and improve a utilization rate of an idle second network the access information may also be a migration allowed list and as shown in table 3 the migration allowed list is used for specifically representing those second networks to which the user equipment is allowed to migrate if the network identifier u201c wlan2 u201d of the second network to which the user equipment is to migrate exists in a migration allowed list of the second network the processor 92 migrates from the first network to the second network u201c wlan2 u201d otherwise if the network identifier u201c wlan3 u201d of the second network to which the user equipment is to migrate does not exist in the migration prohibited list of the second network the processor 92 does not migrate from the first network to the second network u201c wlan3 u201d in this manner the processor 92 may be enabled to determine according to a migration permission status of the second network whether to migrate from the first network to the second network the user equipment migrates to the second network that exists in the migration allowed list which can further optimize resource configuration and improve a.
