  • Patent number: 11153823
    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.

  • Patent number: 10499297
    Abstract: According to a method for handover between distributed access points, an AP 1 receives a handover request sent by a central AP, where the handover request includes an address of a wireless terminal and an identifier of an AP 2; and after receiving the handover request, the AP 1 sends a context handover request to the AP 2, where the context handover request includes an unsent frame of the wireless terminal. In a handover process, the AP 1 may send, to the AP 2, a buffered frame that fails to be sent to the wireless terminal in time, and send the frame to the wireless terminal by using the AP 2, so as to reduce a downlink packet loss when the wireless terminal is handed over between the AP 1 and the AP 2.

  • Publication number: 20190297553
    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. Embodiments of the present invention are applied to a scenario in which a terminal is handed over and roams between Wi-Fi networks on a highway.

  • Patent number: 10278093
    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.

  • Patent number: 10187834
    Abstract: A method for handover between distributed access points (APs), where the method includes a central AP sending a first instruction to an AP 2. The first instruction includes an identifier of the wireless terminal, and the first instruction is used to instruct the AP 2 to start receiving a data frame from the wireless terminal, and forbid the AP 2 to return an acknowledgement frame to the wireless terminal. The central AP sends a handover success notification message to an AP 1 and the AP 2. The handover success notification message includes the identifier of the wireless terminal, and the handover success notification message is used to instruct the AP 1 to stop receiving the data frame from the wireless terminal, and is used to instruct the AP 2 to return the acknowledgement frame to the wireless terminal.
