The invention relates to the technical field of communication, in particular to a time-division processing method and a device therefor, which solve the problems in the prior art, for example, timers in individual service treatment modules are independent from one another, if the time setting of the timers are unreasonable, the CPU is unable to work with maximum efficiency, thereby causing poor convergence performance of the protocol, even broken link of the protocol. In one embodiment, the method comprises the following steps: a strategy execution module adds received wake-up requests from service treatment modules to a wake-up request list; and the strategy execution module determines a wake-up request from the wake-up request list according to a preset wake-up strategy and sends a wake-up message to the service treatment module that transmits the determined wake-up request, to the instruct the service treatment module to execute the service treatment. The time-division processing method increases the utilization ratio of the CPU resources and the convergence performance of the protocol, and prevents the broken link of protocol caused by time-division processing.
