A method for reducing terminal temperature performed by a terminal, the method comprising: connecting the terminal to a first network; monitoring a chip temperature of the terminal; sending rate reduction information to a network device when the chip temperature is greater than a first predetermined threshold, and the rate reduction information being used to trigger reduction in a transmission rate between the network device and the terminal, receiving a first request sent by the network device in response to a first measurement report for reporting to the network device that quality of the first network is lower than a first threshold and the quality of a second network is higher than a second threshold; and switching to a second network based on the first request, wherein a transmission rate between the terminal and the network device when the terminal is connected to the second network is lower than a transmission rate between the terminal and the network device when the terminal is connected to the first network, characterized in that: after the switching to the second network based on the first request, the method further comprises: monitoring the chip temperature, and sending to the network device, when the chip temperature is less than a second predetermined threshold, a second measurement report for reporting to the network device that the quality of the first network is higher than a third threshold and the quality of the second network is lower than a fourth threshold; receiving a second request sent by the network device in response to the second measurement report; and switching the connection to the first network based on the second request. connecting the terminal to a first network; monitoring a chip temperature of the terminal; sending rate reduction information to a network device when the chip temperature is greater than a first predetermined threshold, and the rate reduction information being used to trigger reduction in a transmission rate between the network device and the terminal, receiving a first request sent by the network device in response to a first measurement report for reporting to the network device that quality of the first network is lower than a first threshold and the quality of a second network is higher than a second threshold; and switching to a second network based on the first request, wherein a transmission rate between the terminal and the network device when the terminal is connected to the second network is lower than a transmission rate between the terminal and the network device when the terminal is connected to the first network, characterized in that: after the switching to the second network based on the first request, the method further comprises: monitoring the chip temperature, and sending to the network device, when the chip temperature is less than a second predetermined threshold, a second measurement report for reporting to the network device that the quality of the first network is higher than a third threshold and the quality of the second network is lower than a fourth threshold; receiving a second request sent by the network device in response to the second measurement report; and switching the connection to the first network based on the second request. monitoring the chip temperature, and sending to the network device, when the chip temperature is less than a second predetermined threshold, a second measurement report for reporting to the network device that the quality of the first network is higher than a third threshold and the quality of the second network is lower than a fourth threshold; receiving a second request sent by the network device in response to the second measurement report; and switching the connection to the first network based on the second request.
