Abstract
A location privacy protection method includes generating an identifier update notification message to be sent to at least one access point, where the identifier update notification message includes a first identifier of a wireless terminal, to indicate that the identifier update notification message is to be sent by the wireless terminal. The identifier update notification message further includes second identifier information of the wireless terminal. The method further includes sending the identifier update notification message, so that the access point acquires a second identifier according to the second identifier information, and uses the second identifier as an identifier of the wireless terminal; and sending a subsequent message including the second identifier to the access point, to indicate that the subsequent message is sent by the wireless terminal.
