Management device and method for controlling end-to-end network in wireless communication system

A server for controlling an end-to-end network in a wireless communication system, the server comprising:

• a virtual switch comprising a flow table applier configured to process traffic for a terminal;
• and
• a user plane function (UPF) configured to receive the traffic from the terminal or transmit the traffic to the terminal,
• wherein the flow table applier is configured to identify a network slice configured for the terminal among a plurality of network slices using a plurality of flow tables for processing the traffic and process the traffic according to a flow rule corresponding to the identified network slice, and
• wherein each network slice among the plurality of network slices is configured for a different frequency band.

A method of a management device for controlling an end-to-end network in a wireless communication system, the method comprising:

• configuring a plurality of network slices for a terminal;
• setting a policy applied to the plurality of network slices;
• and
• controlling one or more network entities related to transmission of traffic for the plurality of network slices, based on the policy,
• wherein each of the plurality of network slices is configured for a different frequency band.

A method of a server for controlling an end-to-end network in a wireless communication system, the method comprising:

• identifying a network slice configured for a terminal among a plurality of network slices using a plurality of flow tables for processing traffic for the terminal;
• processing the traffic according to a flow rule corresponding to the identified network slice;
• and
• transmitting the processed traffic to a user plane function (UPF) inside the server or to an entity outside the server,
• wherein each network slice among the plurality of network slices is configured for a different frequency band.
