Abstract: A method for triggering a registrar protocol interaction. The method includes: receiving, by an access point, a probe request sent by at least one station, where the probe request includes an identifier of the access point; determining, by the access point, a first station in the at least one station according to the probe request sent by the at least one station, where the identifier included in the probe request sent by the first station matches an identifier of the access point, and a signal strength of the probe request sent by the first station is greater than a signal strength threshold; and automatically triggering, by the access point, a registrar protocol interaction with the first station.

Abstract: A data transmission method and a device are provided. When determining that the first network element and the second network element is disconnected, the first network element stores identification information of the last frame of data and connection status information that are transmitted before the connection is disconnected. When determining a condition for re-communication is meet, the first network element generates a third key based on a first key and a second key, where the first key is a key used to transmit the last frame of data, and the second key includes a key used by the first network element and the second network element to transmit each of j frames of data before the last frame of data. The first network element communicates with the second network element based on the third key, identification information of an ith frame of data, and the connection status information.

Abstract: A device includes one Wi-Fi chip and a first antenna and a second antenna connected to the Wi-Fi chip. The first antenna wirelessly communicates with another device in a Wi-Fi P2P manner through a first channel. The second antenna wirelessly communicates with a first wireless signal source in a Wi-Fi AP manner through a second channel. After the first channel and the second channel are two different channels on a same frequency band, time division multiplexing is performed on the first antenna and the second antenna, and a second wireless signal source whose frequency band is different from that of the first wireless signal source is detected within preset duration, the second channel is adjusted to a channel which is different from the first channel on different frequency bands, and the second antenna wirelessly communicates with the second wireless signal source in the Wi-Fi AP manner through the adjusted second channel.

Abstract: A packet sending method includes, when a network element in a serial network receives a to-be-forwarded packet at a previous node from a previous network element, and when the network element needs to send a to-be-sent packet at a current node, determining whether the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, where the network element is an intermediate network element in the serial network; when the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node can be superimposed, superimposing the to-be-sent packet at the current node and the to-be-forwarded packet at the previous node, to obtain a to-be-forwarded packet at the current node; and sending the to-be-forwarded packet at the current node to a next network element of the network element.

Abstract: A method for selecting a management frame antenna based on a master-slave network and an apparatus are provided. In one example method, when a preset condition is met, a signal quality collection instruction is sent by a master device to a first slave device and a second slave device, so as to receive returned signal quality information. A management frame antenna is selected for the first slave device and a management frame antenna for the second slave device according to the received signal quality information, so that the selected management frame antennas can implement signal coverage optimization in an entire area managed by the master device.

Abstract: A handover method in a master-slave network, and a master device, and slave devices are provided. The method includes when a master device or a first slave device determines that a user device needs to be handed over to a second slave device, the first slave device sends, to the second slave device, a first identifier of a first network interface allocated by the first slave device to the user device, and first network connection information used after the user device establishes a connection to the first network interface of the first slave device. The first identifier of the first network interface and a second identifier of the user device correspond on a one-to-one basis. The first slave device deactivates the first network interface and the second slave device activates a second network interface.

Abstract: A channel automatic selection and switching method and system, where after an access point (AP) and a station (STA) are successfully coupled, the AP performs quality detection on a first channel, determines, based on a quality detection result, whether the first channel needs to be switched, performs quality detection on backup channels when the first channel needs to be switched, and starts channel switching for the AP and the STA when there is a backup channel of higher quality. Because the backup channel and the first channel use same network coupling information, for the STA, a data link layer coupling is the same. Therefore, during first channel switching, a coupling interruption phenomenon does not occur, and thereby completing first channel switching without interrupting the data link layer coupling between the AP and the STA.
