<p>A congestion control method and device are disclosed. The method comprises that: an MTC-IWF receives first instruction information from an SMS-SC via a T4 interface, wherein the first instruction information is used to instruct the MTC-IWF to perform a congestion control on Trigger information; the MTC-IWF performs the congestion control according to the first instruction information; and the SMS-SC receives congestion indication information from a serving node where a user equipment locates and performs a congestion control on trigger information according to the congestion indication information. The present invention addresses the problem of how to perform a congestion control by a T4 interface existing in related art, improves the robustness and the stability of the system and enables an MTC-IWF and an SMS-SC to perform a congestion control on trigger information when the trigger information is sent via a T4 interface.</p> |
