Method and apparatus for executing virtualized network function

A server for executing a virtualized network function in a wireless communication system, the server comprising:

• a memory storing one or more instructions;
• and
• at least one processor configured to execute the one or more instructions stored in the memory to:
• obtain traffic processing information and mobile edge computing (MEC) service usage information regarding user equipments (UEs) that have accessed to the server via a plurality of base stations, wherein the traffic processing information includes traffic information indicating an amount of traffic occurred on a virtualized random access network, vRAN, function and resource information indicating physical resources including hardware components used for processing the traffic,
• identify an amount of MEC service usage based on the traffic processing information and the MEC service usage information,
• predict, an amount of traffic to occur and an amount of MEC service usage to occur based on the amount of the traffic occurred on the vRAN function and the amount of the MEC service usage, and
• determine, based on the predicted amount of the traffic and the predicted amount of the MEC service usage, a type of the physical resources on which each of a software component for the vRAN function and an MEC function in the server is to be executed.

A computer program product comprising a non-transitory computer-readable recording medium having stored therein a program which causes a server to perform a method of executing a virtualized network function, the method comprising:

• obtaining traffic processing information and mobile edge computing (MEC) service usage information regarding a plurality of user equipments (UEs) that have accessed to the server via a plurality of base stations, wherein the traffic processing information includes traffic information indicating an amount of traffic occurred on a virtualized random access network, vRAN, function and resource information indicating physical resources including hardware components used for processing the traffic,
• identifying an amount of MEC service usage based on the traffic processing information and the MEC service usage information;
• predicting an amount of traffic to occur and an amount of MEC service usage to occur based on the amount of the traffic occurred on the vRAN function and the amount of the MEC service usage;
• and
• determining, based on the predicted amount of the traffic and the predicted amount of the MEC service usage a type of the physical resources on which each of a software component for the vRAN function and an MEC function
• in the server is to be executed.
