Abstract

The embodiment of the invention provides a wireless terminal and an auxiliary antenna state control method thereof. The method comprises the following steps of: acquiring the temperature of the wireless terminal; judging a relation between the temperature of the wireless terminal and a temperature threshold upper limit as well as a temperature threshold lower limit; when the temperature of the wireless terminal is higher than the temperature threshold upper limit, switching the auxiliary antenna off; or when the temperature of the wireless terminal is lower than the temperature threshold lower limit, switching the auxiliary antenna on. Due to the adoption of the method, overheat of the wireless terminal and potential safety hazards such as chip over-temperature, aging failure or short-circuit burning and the like caused by the overheat can be prevented. Simultaneously, continuous use of the wireless terminal by a user can be ensured and impacts (sudden change of flow speed, offline and the like) on the user during practical use are minimized.
