Disclosed in the embodiments of the present application are a service scheduling method, an apparatus and a system. A sub-device will negotiate with an associated STA the energy saving time and the wake-up time of the STA, that is, negotiate when the STA is in the energy saving state and when the STA processes the wake-up state; then, the sub-device reports the negotiated wake-up time of the STA to a master device; furthermore, the master device schedules related data of the STA on the basis of the wake-up time of the STA.
