  • Publication number: 20170289878
    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.

  • Patent number: 9680690
    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.

  • Publication number: 20170006494
    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: 9413592
    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.

  • Patent number: 9055551
    Abstract: The present disclosure relates to the mobile communication field and discloses a prefix allocation method, a network system, and a Local Mobility Anchor (LMA). With the prefix allocation method, the network system and the LMA provided in the present disclosure, the problem that a shared prefix cannot be allocated to a multi-interface (IF) Mobile Node (MN) is solved. The prefix allocation method includes: receiving a registration request for a second IF of the MN from a Mobile Access Gateway (MAG); obtaining a first Home Network Prefix (HNP) that is already allocated to a first interface (IF) of the MN; and allocating the first HNP shared with the first IF to the second IF. The LMA obtains the first HNP that is already allocated to the first IF and allocates the first HNP to the second IF. In this way, a shared prefix is allocated to the multi-IF enabled MN.

  • Patent number: 8917623
    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.
