Admission control method and admission request method in communication network system

An admission control method performed by a slice controller, for performing a slice admission request admission control in a communication network system, said communication network system deploying a plurality of network slices,

• the admission control method comprising steps of:
• a) receiving at least one slice admission request from at least one user equipment deployed in the communication network system, said slice admission request containing at least data related to slice request parameters,
• b) obtaining network parameters related to at least an overall state of network resources in the plurality of network slices,
• c) determining, for each network slice of the plurality of network slices:
• a slice service variable related to required network resources from the network slice to admit the slice admission request, said slice service variable being determined based on at least the slice request parameters and the network parameters,
• a slice utility gain related to a variation of a slice utility function to be expected from a utilization of the required network resources from the network slice to admit the slice admission request, said slice utility function depending on the slice service variables respectively associated to the plurality of the network slices, the slice utility gain being determined based on at least a machine learning model,
• a slice demand load related to consumed network resources in the network slice if the slice admission request is admitted, said slice demand load being determined based on at least the slice utility gain of the network slice,
• d) transmitting the slice demand loads respectively associated to the plurality of the network slices to the user equipment,
• e) feeding the slice demand loads respectively associated to the plurality of the network slices to the machine learning model,
• f) based on the slice utility gain, determining a decision on the admission of the slice admission request.
