The embodiment of the invention provides a communication method based on the circuit domain backspacing technology. The method comprises the steps that when a communication triggering action is monitored, measurement is trigged to obtain a measurement report, when a measurement control message sent by an evolution base station is received, the measurement report is uploaded to the evolution base station, and the evolution base station is used for setting up communication through the measurement report according to the circuit domain backspacing technology. According to the communication method and device, a mobile device is monitored, when a user starts a Bluetooth headset, or connects a vehicle Bluetooth communication device, or starts a dial plate interface and other operations, the mobile device triggers measurement of a heterogeneous network cell in advance, network side triggering is not needed, time for the user to insert the headset, inputting phone numbers and other operations is generally smaller than 2 seconds, and the time span requirement of measurement is met. Time needed by measurement of the heterogeneous network cell in the following signaling interactive process is saved, and delay built based on CSFB communication is reduced.
