Embodiment
[0074] The specific conditions of this example are: the number of mobile users N within the coverage of a single physical macro base station is set to 12, the number of slices M is set to 3, that is, 3 network slices obtain spectrum resources from the physical macro base station to provide 12 mobile users Different data transfer services. In the simulation environment where the signal-to-noise ratio (SNR) is 1db to 20db, the channel fading obeys the Rayleigh distribution.
[0075] Based on the above experimental conditions, first obtain the delay sensitivity of different users, and quantify it as Then, the service request A made by the mobile user n assigned to different network slices. After the network slice receives the service request, it calculates the cost function μ m (ω m ), and sequentially update the virtual price ω m and penalty factor q m , until the virtual price converges, the base station allocates spectrum resource b according to the virtual price m Sli...
