1. A method for operating a network device supporting service continuity between a first network and a second network, the method comprising:
requesting slice analytics for selection of a slice from a network data analytics function (NWDAF) of the first network before a terminal moves from the first network to the second network;
receiving the slice analytics from the NWDAF of the first network; and
selecting a slice to be used in the second network to provide a service to the terminal among a plurality of slices based on the slice analytics received from the NWDAF of the first network,
wherein the network device is located within the second network,
wherein the slice analytics includes information on quality of service (QOS) and key performance indicator (KPI) provided by a network slice.
