Abstract: Provided are a method of enablement of a service application programming interface (API) exposed by an edge application server (EAS) and a device for performing the same. A service API enablement method includes performing, by a first EAS, EAS registration with an edge enabler server (EES), performing, by a second EAS, EAS registration with the EES, transmitting, by the second EAS, a service API publish request to the EES in order to publish a service API of the second EAS, discovering, by the first EAS, a service API in the EES, and invoking, by the first EAS, the service API discovered in the EES and published by a second EAS, wherein the service API publish request may include a service key performance indicator (KPI).

Abstract: An interworking method between 5G multi-access edge computing (MEC) platforms using a common application programming interface framework (CAPIF) is disclosed. The MEC platform interworking method includes requesting an European telecommunications standards institute (ETSI) MEC to discover a MEC service by an edge enabler server (EES), in response to a request of an edge application server (EAS), obtaining, by the EES, information of a matched MEC service in response to the request of the EAS from the ETSI MEC, and transmitting the information of the matched MEC service by the EES such that the EAS invokes a MEC service provided by the ETSI MEC.

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.
