摘要： 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.

摘要： 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.

摘要： 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.

摘要： A method, a network adapter, a host system, and a network device for implementing a network adapter offload function. If a data packet received by the network adapter or the host system is a data packet unknown to the network adapter, the data packet unknown to the network adapter is parsed, a new policy entry is generated, and the new policy entry is updated into the host policy table and the network adapter policy table. Therefore, for a packet that includes a new proprietary or standard protocol header Tag, only a functional module that parses the packet needs to be updated, so that the functional module is capable of processing such a packet and delivering a new policy entry to the host policy table and the network adapter policy table and the network adapter does not need to be changed.
