Abstract: Provided is a communication method and apparatus based on access network paging and core network paging. A communication method performed by an anchor radio access network (RAN) receives a signaling message or a data packet for a user equipment (UE) from a core network, triggers paging for the UE, and transmits a paging request to the core network in response to a failure of the paging. The core network is configured to transmit a core network (CN) assisted paging request message to a new RAN within a determined target paging area in response to the paging request, and the new RAN is configured to perform the paging for the UE based on the CN assisted paging request message.

Abstract: Provided is a communication method and apparatus using network slicing. A communication method of a communication apparatus performing communication with a user equipment receives a predetermined request from the user equipment, selects a single network slice instance to be allocated to the user equipment from among a plurality of network slice instances in the communication apparatus in response to the request, selects a single network function instance to be allocated to the user equipment from among a plurality of network function instances included in the selected network slice instance. The network slice instance is in an instantiated form of a network slice that includes at least one network function and resource for providing a network service having a predetermined capability and characteristic to the user equipment.
