The present invention provides a location privacy protection method, apparatus, and system. The 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, and the identifier update notification message further includes second identifier information of the wireless terminal; 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. Therefore, the wireless terminal may periodically or aperiodically send an identifier update notification message that is used to update an identifier of the wireless terminal, so that a value of an identifier field, in a subsequent message, for the wireless terminal is not fixed; in this way, exposing and tracing of a location of a wireless terminal that are caused due to a fixed value of an identifier field, in a message, for a sending device can be avoided, effectively protecting location privacy of a user that uses the wireless terminal. |
