Abstract
Embodiments provide a method, a device, and system to implement session management on a UPF network element. The method includes: determining, by a network device, that a first logical interface group on a first UPF network element needs to be migrated; determining, by the network device, a second UPF network element for the first logical interface group; sending, by the network device to the second UPF network element, configuration information of the first logical interface group and information about a first IP address segment corresponding to the first logical interface group, to restore the configuration information of the first logical interface group and the information about the first IP address segment on the second UPF network element; and sending, by the network device, a first message used to restore, on the second UPF network element, information about one or more sessions corresponding to the first logical interface group.
