Abstract: The embodiments of the present invention provide a congestion control implementation method and apparatus, where the method includes: determining one or more user equipments for which single radio voice call continuity (SRVCC) offloading needs to be performed; sending an SRVCC offload message to an E-UTRAN NodeB serving the one or more user equipments, so that when triggering an SRVCC handover procedure, the E-UTRAN NodeB switches the one or more user equipments from a Long Term Evolution (LTE) domain to a circuit switched (CS) domain. When the SRVCC handover procedure is completed, the one or more user equipments can be switched from VoLTE user equipments to VoCS user equipments. In this way, LTE cell load can be alleviated and QoS of the one or more user equipments can be guaranteed.
