Abstract: This application provides a handover method that is based on DC, including: sending, by a source base station, a handover request to a target base station, where the handover request carries a target base station user equipment (UE) aggregate maximum bit rate (UE-AMBR) and/or network slice information of UE; and receiving, by the source base station, a handover request feedback sent by the target base station. A UE capability is coordinated between the source base station and the target base station, so that it is ensured that a technical effect of the UE capability is not exceeded during a DC-based handover. The coordination of the UE capability may be implemented by the source base station, or may be implemented by the target base station.

Abstract: Embodiments of the present invention propose a communication method. The communication method includes: obtaining, by a base station, DRB configuration information, where the DRB configuration information is used to determine a mapping relationship between serving cells and DRBs used to carry data of different service types; and sending the DRB configuration information to a terminal, so that the terminal communicates with the base station in a serving cell corresponding to a DRB. The embodiments of the present invention further disclose a base station and a terminal to which the communication method is applied.

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.
