Third party positioning method and terminal

The invention discloses a third party positioning method and a terminal. The method comprises the following steps that: a terminal calculates through a MSB (Most Significant Bit) positioning mode, while being failed in positioning within timeout duration, returns back to a MSA positioning method for calculation. Moreover, the invention further provides a MSB positioning timeout duration adaptive adjustment method, the method comprises the following steps of: setting a timeout duration T controller, taking the positioning timeout duration and the positioning success of the MSB mode within a period of observation time S as the inputs of the controller, and then, executing adaptive control, thereby meeting the requirements of different scenes. The method and the terminal provided by the invention effectively improve precision of outdoor positioning, and can effectively reduce positioning delay and load on a positioning platform; and the adaptive adjustment time controller T can effectively satisfy the requiremen
