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: Sleeping and wake-up methods and apparatuses of a master-slave network, and a power saving system of a master-slave network, are provided. The method includes: obtaining, from a link management list, running statuses of slave devices on links; determining a target device, where the target device is a slave device whose running status is idle; if running statuses of the target slave device to an end slave device on a link on which the target slave device is located are all idle, determining that a sublink from the target slave device to the end slave device on the link on which the target slave device is located is a target sublink; and sending a power saving message to at least one slave device on the target sublink, so that the slave device enters a sleep and listen state when receiving the power saving message.

Abstract: Example sleeping and wake-up methods and apparatuses of a master-slave network, and a power saving system of a master-slave network, are described. One example method includes obtaining running statuses of slave devices on links from a link management list. A target device is determined. The target device is a slave device whose running status is idle. If running statuses of the target slave device to an end slave device on a link on which the target slave device is located are all idle, it is determined that a sublink from the target slave device to the end slave device on the link on which the target slave device is located is a target sublink. A power saving message is sent to at least one slave device on the target sublink, so that the slave device enters a sleep and listen state when receiving the power saving message.

Abstract: The present invention provides an IP address allocation method for a master-slave network, an apparatus, and a system. A master device generates an IP address sub-segment group, and separately sends at least one IP address sub-segment in the IP address sub-segment group to at least one slave device, so that the slave device can use a received IP address sub-segment as a DHCP server address and allocate an IP address to a user device. In this way, the slave device can directly allocate the IP address to the user device, so that an IP address allocation time is reduced.

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: In an embodiment a screen projection method includes determining, by a project end, to-be-projected data when a screen projection function is enabled, obtaining, by the project end, first data permission of the project end for the to-be-projected data and second data permission of a receive end for the to-be-projected data when the to-be-projected data is media data and projecting, by the project end, the to-be-projected data onto the receive end in a screen mirroring manner when the first data permission is higher than the second data permission or projecting, by the project end, the to-be-projected data onto the receive end in a digital living network alliance manner when the first data permission is lower than the second data permission.
