Abstract
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method performed by a first network entity in a wireless communication network is provided. The method includes transmitting, to a second network entity, a first message including data to be used in a plurality of networks included in a virtual network (VN) group, a VN identifier (ID), group data, and receiving, from the second network entity in response to the first message, a second message including the data to be used in the plurality of networks, the VN ID, the group data, information indicating a processing result related to the first message.
Claims18
A method performed by an application function (AF) in a wireless communication network, the method comprising:
- transmitting, to a network exposure function (NEF), a first message including data to be used in a plurality of networks included in a virtual network (VN) group, a VN identifier (ID), and group data;
- and
- receiving, from the NEF in response to the first message, a second message including the data to be used in the plurality of networks, the VN ID, the group data, a first single network slice selection assistance information (S-NSSAI) used for a VN within a first network in which the NEF belongs, and information indicating a processing result related to the first message,
- wherein the data to be used in the plurality of networks includes a VN network ID indicating an ID of a second network in which a user plane function (UPF) to which traffic to be used in the plurality of networks is to be transmitted is located, and a second S-NSSAI of used for the VN across the plurality of networks including the second network in which the UPF is located, and
- wherein the first S-NSSAI is mapped to the second S-NSSAI.
