Abstract

Disclosed are a joint positioning method and device, and the method includes: a positioning module is enabled after a terminal receives a positioning request; the positioning module determines a primary positioning submodule implementing a primary positioning mode and an auxiliary positioning submodule implementing an auxiliary positioning mode according to a communication scenario or a predetermined setting; implementing respectively positioning by the primary positioning submodule and by the auxiliary positioning submodule, and outputting respective positioning results to a comparison module of the terminal; the comparison module compares the positioning results, selects an optimal positioning result and sends the optimal positioning result and/or positioning results other than the optimal positioning result to the primary positioning submodule; and the primary positioning submodule reports the optimal positioning result and/or positioning results other than the optimal positioning result to a server or the terminal through an interaction module of the terminal. The present disclosure can solve a problem that existing positioning applications have limited methods and poor accuracy can be better solved.
