After the terminal determines, based on the first wake-up signal, that the first terminal subgroup to which the terminal belongs is a terminal subgroup that needs to be woken up, the terminal is woken up. In a paging process, the terminal does not need to continuously monitor a paging occasion, but monitors an associated paging occasion after being woken up.
