Abstract: A wireless network handover method and apparatus are provided, relating to the communications field, and capable of resolving a problem of a service packet loss during a handover of a terminal. The method includes: obtaining, by a handover device, a distance between a terminal and a current access point, to determine a change trend of the distance between the terminal and the current access point; and if the handover device determines, based on a correspondence between the change trend and a neighboring access point of the current access point, a target access point to which the terminal is to be handed over, handing over, by the handover device, the terminal from the current access point to the target access point. Forgoing solution is applied to a scenario in which a terminal is handed over and roams between Wi-Fi networks on a highway.

Abstract: A method, an apparatus, and a system for quality of service (QoS) parameter configuration in a wireless local area network (WLAN), where the method includes sending, by a network device, a default first QoS parameter set to a terminal, sending, by the network device, a QoS parameter set modification message including a second QoS parameter set to the terminal, where the second QoS parameter set is different from the first QoS parameter set, and the QoS parameter set modification message is a unicast beacon frame or an active probe response frame. In this way, the second QoS parameter set different from the first QoS parameter set is sent to the terminal using the unicast beacon frame or the active probe response frame, which ensures that the network device dynamically adjusts a QoS parameter set of the terminal on a per terminal basis, thereby improving data transmission efficiency and user experience.

Abstract: An apparatus and a method for providing an efficient multi-client access in a WLAN, the method comprising the step of: when the number of clients exceeds a threshold, creating at least two virtual access points (VAP1, VAP2, VAP3); load balancing by distributing workloads across the created at least two virtual access points; and dynamically allocating at least one quality of service parameter (e.g., timeslots, AIFS, TXOP, maximum and minimum contention window) to each of the created at least two virtual access points.

Abstract: The present invention provides a positioning method, device and system, which are applied to indoor WLAN positioning. A positioning server obtains location service information of APs in a set of APs to be measured; selects three APs to be measured in the set of APs to be measured according to a preset rule, and calculates a first coordinate of a terminal; if a calculated RSSI value of an unmeasured AP is not smaller than a difference between the measured RSSI value and a preset threshold, determines that signals of the unmeasured AP are not affected by reflection; and uses the first coordinate as a location coordinate of the terminal if all the three APs to be measured have been measured, thereby positioning the terminal.

Abstract: A device for assigning radio channels to radio transceiver devices. The device comprises an interface configured to receive two or more radio communication values, each associated with a radio transceiver device. The device comprises a processor configured to calculate an ordering of two or more radio transceiver devices based on radio communication values and build, according to the ordering, one or more rooted tree representing assignment of available radio channels to first radio transceiver devices according to the ordering. A branch of the rooted tree is selected according to a cost function value calculated along each branch. The processor is configured to assign the available radio channels to the radio transceiver devices according to the selected branch.
