Title: METHOD, RELATED DEVICE AND SYSTEM FOR WIRELESS TERMINAL POSITIONING
Abstract:
A method, related device and system for wireless terminal positioning are disclosed. The method includes the following steps: a wireless terminal obtains a positioning service period and a positioning channel identifier from a first access point; the wireless terminal switches to the positioning channel in the positioning service period; the wireless terminal broadcasts a position measurement message via the positioning channel to enable at least three access points of the access point group to which the first access point belongs to obtain positioning measurement data so as to estimate the position of the wireless terminal after the at least three access points receive the position measurement message. The embodiment of the present invention can shorten wireless terminal positioning time, reduce power consumption and improve network wireless channel utilization.
