Abstract: Embodiments of the present invention disclose a linkage policy implementation method, which includes: receiving, by a linkage proxy module, a linkage policy request delivered by a third-party application service; calling a corresponding protocol converter according to a protocol identifier in the linkage policy request, and performing protocol conversion for the linkage policy request to convert it into a linkage policy request in a set protocol format; and sending the protocol-converted linkage policy request to a linkage client to instruct the linkage client to parse the linkage policy request based on the set protocol and execute linkage policy configuration. With the present invention, a linkage proxy is set to execute protocol conversion of various protocols. Therefore, the cost of the linkage client would not be increased for supporting multiple protocols; and when third-party applications are increased or decreased, it is unnecessary to reconfigure the linkage client.

Abstract: 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.

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 coordinated transmission method for a wireless local area network and an apparatus are disclosed. A sharing access point (AP) sends a first frame to a first station (STA) on a channel when a condition is met, to detect an interference resource unit, the channel is a channel on which the sharing AP and a first shared AP perform coordinated transmission. The sharing AP is a serving AP of a first STA. The first frame indicates the first STA to use a first resource unit when replying to the first frame. The interference resource unit is the first resource unit on which the reply from the first STA is not received.

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 wireless access point, a terminal device, and a method for waking up a terminal device by a wireless access point. The terminal device includes a primary radio frequency circuit and a wake-up radio (WUR) radio frequency circuit. The WUR radio frequency circuit only receives a radio signal and operates on a specified channel. If the WUR radio frequency circuit receives a wake-up frame on the specified channel and the terminal device is a to-be-woken-up terminal device, the WUR radio frequency circuit wakes up the primary radio frequency circuit. The wake-up frame includes an identifier of the to-be-woken-up terminal device. The primary radio frequency circuit operates on an operating channel of the primary radio frequency circuit after being woken up.

Abstract: A method for a handover between distributed access points is disclosed, including receiving, by a central AP, an Ethernet frame; adding, by the central AP, a sequence number to the frame according to an address of a wireless terminal; sending, by the central AP to an AP 1, the frame to which the sequence number is added, and storing the frame to which the sequence number is added in a historical frame set of the wireless terminal; and sending, by the central AP, a frame in the historical frame set of the wireless terminal to an AP 2 when the wireless terminal is handed over from the AP 1 to the AP 2. If the wireless terminal moves fast, the central AP can send the frame in the historical frame set to the wireless terminal using the AP 2, so that a downlink packet loss is reduced.

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.
