Abstract: This application relates to the field of wireless communication technologies, and discloses a terminal scheduling method and apparatus, to reduce interference between terminals. A centralization device determines, based on information of a terminal, mutual interference between a terminal in a first cell and a terminal in a second cell when the terminal in the first cell and the terminal in the second cell are scheduled on a first time-frequency resource; and determines whether the terminal in the first cell and the terminal in the second cell are allowed to be scheduled on the first time-frequency resource. This can reduce strong interference between the terminals.

Abstract: The present disclosure relates to service level agreement (SLA) performance prediction methods, apparatuses, and devices. In one example method, a first network device obtains timestamps and packet lengths of a plurality of data packets. The first network device determines an arrival time interval of each of the plurality of data packets based on the timestamps of the plurality of data packets, where arrival time intervals of the plurality of data packets constitute a time interval sequence according to an arrival order. The first network device determines time domain feature parameters of the plurality of data packets based on a Markovian arrival process (MAP) model and the time interval sequence.
