A priority-based resource processing method, applicable to an Internet-of Things system, comprising: calculating (S1 10) a first priority of a first resource and a second priority of a second resource; determining whether the first priority of the first resource is higher than the second priority of the second resource; and when determining that the first priority is higher than the second priority, responding to a first operation request corresponding to the first resource, characterized in that, before calculating the first priority of the first resource and the second priority of the second resource, the priority-based resource processing method further comprises: obtaining first priority impact parameters of the first resource and second priority impact parameters of the second resource; wherein, calculating the first priority of the first resource comprises: calculating the first priority of the first resource according to the first priority impact parameters of the first resource; wherein, calculating the first priority of the first resource according to the first priority impact parameters of the first resource comprises: assigning weight coefficients for the first priority impact parameters of the first resource; and performing calculations on the first priority impact parameters and the weight coefficients corresponding to the priority impact parameters, to obtain the first priority; wherein the first priority impact parameters comprise one or more of a first base priority, a number of subscriptions of the first resource, a number of retrieves of the first resource and a number of updates of the first resource; wherein the first priority is a sum of a first weight coefficient * the first base priority, a second weight coefficient * the number of subscriptions of the first resource, a third weight coefficient * the number of retrieves of the first resource and a fourth weight coefficient * the number of updates of the first resource; and wherein at least one of the first weight coefficient, the second weight coefficient, the third weight coefficient and the fourth weight coefficient is not zero. calculating (S1 10) a first priority of a first resource and a second priority of a second resource; determining whether the first priority of the first resource is higher than the second priority of the second resource; and when determining that the first priority is higher than the second priority, responding to a first operation request corresponding to the first resource, characterized in that, before calculating the first priority of the first resource and the second priority of the second resource, the priority-based resource processing method further comprises: obtaining first priority impact parameters of the first resource and second priority impact parameters of the second resource; wherein, calculating the first priority of the first resource comprises: calculating the first priority of the first resource according to the first priority impact parameters of the first resource; wherein, calculating the first priority of the first resource according to the first priority impact parameters of the first resource comprises: assigning weight coefficients for the first priority impact parameters of the first resource; and performing calculations on the first priority impact parameters and the weight coefficients corresponding to the priority impact parameters, to obtain the first priority; assigning weight coefficients for the first priority impact parameters of the first resource; and performing calculations on the first priority impact parameters and the weight coefficients corresponding to the priority impact parameters, to obtain the first priority; wherein the first priority impact parameters comprise one or more of a first base priority, a number of subscriptions of the first resource, a number of retrieves of the first resource and a number of updates of the first resource; wherein the first priority is a sum of a first weight coefficient * the first base priority, a second weight coefficient * the number of subscriptions of the first resource, a third weight coefficient * the number of retrieves of the first resource and a fourth weight coefficient * the number of updates of the first resource; and wherein at least one of the first weight coefficient, the second weight coefficient, the third weight coefficient and the fourth weight coefficient is not zero.
