Abstract: A data communications method, apparatus, and system are provided. The method includes: sending an association request message to an access point; receiving an association response message sent by the access point, where the association response message includes an association identifier; generating a data frame, where a format of the data frame is a simplified frame format, and a frame header of the data frame includes a source address and a destination address, where the length of the source address is shorter than the length of a Media Access Control (MAC) address, and the source address includes the association identifier, the association identifier and a multicast unicast indicator, the association identifier and a data type, or the association identifier, the data type, and the multicast unicast indicator; and sending the data frame to the access point.

Abstract: An indoor positioning method includes: sending, by a client, a position request instruction to at least three access points; receiving, by the client, a response message sent by each access point in response to the request instruction; sending, by the client, a corresponding measurement report message to each access point, so that each access point obtains a radio signal flight time between itself and the client; and receiving, by the client, a position estimation result from a network side, where the network side performs a comparative calculation on the radio signal flight time received from each access point and a sampling time measured in advance between each access point and each of multiple sampling points, and the position estimation result is an obtained coordinate location of a sampling point whose corresponding sampling time has a minimum time difference from the radio signal flight time received from each access point.

Abstract: A method for exchanging a wireless network management message includes: an access point device receives a terminal management message sent by a terminal, and in a contention-free period, sends a management polling frame to the terminal. After receiving, in a contention-free period, the management polling frame sent by the access point device, the terminal sends a next terminal management message to the access point device. The embodiments of the present invention further provide an access point device and a terminal for exchange a wireless network management message. Because the access point device controls the terminal to send a wireless network management message in a contention-free period, a problem of a conflict in a contention period among a plurality of terminals that have accessed a network is avoided, thereby decreasing time for a terminal to access a network.
