Abstract:
The present invention discloses a clock synchronization method in a multi-clock domain, a line card, and an Ethernet device. The method includes: acquiring, by a sending line card, M clock frequency differences that are determined by a receiving line card and that are of M uplink interfaces corresponding to M downlink interfaces on the sending line card, where the M uplink interfaces are uplink interfaces on the receiving line card, and M is a positive integer; and adjusting, by the sending line card by using each clock frequency difference of the M clock frequency differences of the M uplink interfaces and based on a correspondence between the M downlink interfaces and the M uplink interfaces, a transmit clock of an interface corresponding to the clock frequency difference.
Abstract:
An operation mode switching method and user equipment are disclosed, so that an operation mode of the user equipment can be automatically switched. A specific solution is: determining, by user equipment, that a current data transmission rate of the user equipment is less than a first rate threshold, and/or a battery temperature of the user equipment is greater than a first temperature threshold; determining, by the user equipment, that the user equipment is in a CA operation mode; changing, by the user equipment, a transmission mode parameter of the user equipment to a transmission mode parameter corresponding to a non-CA operation mode; and restarting, by the user equipment, a communications module of the user equipment, and sending a first access request to a base station, where the first access request carries the transmission mode parameter corresponding to the non-CA operation mode.

Abstract:
This application provides a cross-device authentication method and an electronic device. The method is applied to a first electronic device. The first electronic device is connected to a second electronic device, and the method includes: The first electronic device receives a target operation performed by a user on a first interface of the first electronic device. The target operation is for triggering access to a first service, and the first service is associated with the second electronic device. The first electronic device obtains a target authentication manner corresponding to the target operation, and then the first electronic device acquires authentication information based on the target authentication manner, and sends an authentication request to the second electronic device. The authentication request includes the authentication information, the authentication request is for requesting the second electronic device to perform authentication on the first service, and the second electronic device generates an authentication result after performing authentication on the first service. The method is for implementing cross-device authentication information acquisition, to improve convenience of an authentication operation.
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 data transmission method and a smart household control device are provided. The smart household control device sends or receives WiFi data within a first preset period in each preset timing cycle if a smart household control device needs to send or receive WiFi data and ZigBee data; and when the first preset period ends, it stops sending or receiving WiFi data, and sends a first control instruction to a wireless access point device, where the first control instruction is used to instruct the wireless access point device to stop sending WiFi data to the smart household control device; and then it sends or receives ZigBee data within a second preset period in each preset timing cycle, where the first preset period and the second preset period do not overlap. So interference can be avoided between WiFi communication and ZigBee communication.
