Abstract: A method for controlling a specific absorption rate (SAR) of a wireless communications device and a wireless communications device, and the wireless communications device includes a first antenna and a second antenna. The method includes transmitting, by the wireless communications device, a radio frequency signal using the first antenna, and stopping using the first antenna and starting transmitting the radio frequency signal using the second antenna when transmit power of the first antenna is greater than first preset power and a first time period elapses to enable the wireless communications device to meet an SAR standard. There is no backoff of antenna transmit power in a process of controlling the SAR of the wireless communications device. Therefore, communication quality of the wireless communications device is ensured while the SAR standard is met.

Abstract: A communications system switching method and a terminal device establish, by the terminal device, a connection to a first communications system, run a first application, obtain a QoS value of a second communications system, determine based on a preset policy and a QoS requirement of the first application, whether the QoS value of the second communications system meets the QOS requirement of the first application. When the QoS value of the second communications system meets the QOS requirement of the first application, the terminal device disconnects from the first communications system and establishes a connection to the second communications system.
