The present invention is applicable to the field of communications technologies, and provides an method, the method includes: when a CS service and PS service of a local LTE single-card dual-standby multi-mode terminal are concurrent, detecting, by a local LTE single-card dual-standby multi-mode terminal, whether a peer communication terminal that is performing voice communication with it is in a voice silent period; when detecting that the peer communication terminal is not in the voice silent period, receiving, by the local LTE single-card dual-standby multi-mode terminal, downlink data in an LTE system, and suspending, by the local LTE single-card dual-standby multi-mode terminal, sending of uplink data in the LTE system at the same time; and when detecting that the peer communication terminal is in the voice silent period, sending the uplink data and receiving the downlink data, by the local LTE single-card dual-standby multi-mode terminal, in the LTE system.
