1. A method, applied to a terminal having a plurality of subscriber identification module (SIM) cards, and comprising:
sending, by the terminal to a source base station, one piece of binding signaling that carries SIM card binding information, wherein the SIM card binding information comprises information about the plurality of SIM cards of the terminal;
receiving, by the terminal, radio resource control reconfiguration information sent by the source base station, wherein the radio resource control reconfiguration information comprises the information about the plurality of SIM cards and configuration parameters used by the terminal to connect the plurality of SIM cards to a target base station;
switching, by the terminal in a switching operation based on the configuration parameters, the plurality of SIM cards from being connected to the source base station to being connected to the target base station; and
sending, by the terminal, radio resource control reconfiguration complete information to the target base station, wherein the radio resource control reconfiguration complete information comprises the information about the plurality of SIM cards that complete the switching operation.
