The present invention relates to the field of communications technologies, and in particular, to a circuit switched service processing method and a terminal. In the method, when a terminal needs to execute a circuit switched service again after completing the execution of the circuit switched service once, the terminal executes the circuit switched service again instead of immediately returning to a first network, and then returns to the first network when a preset condition is met, which avoids a process in which the terminal first returns from a second network to the first network after completing the execution of the circuit switched service each time, and then falls back from the first network to the second network to execute the circuit switched service again. Therefore, power consumption of the terminal is reduced, utilization of radio resources is improved, and a delay of the circuit switched service is shortened.
