Abstract:
Embodiments of the present invention provide an information query method and device, which can reduce a waste of resources in an information query process, and decrease power consumption. The method includes: sending, by a requesting device in a broadcast manner, a first query request message, where the first query request message carries a first query condition and information about a group identity; and when the requesting device receives a first query response message sent by a responding device that meets the first query condition, sending, by the requesting device, a second query request message that uses the group identity as a receiving address, so that the responding device processes the second query request message.
Abstract:
The present invention discloses an application data synchronization method and an apparatus. When a first operating system and a second operating system are installed in a terminal, and a first application and a second application that have a same function are installed on the first operating system and the second operating system respectively, the method includes: when the second application runs on the second operating system, performing the function by using second application data, and updating the second application data, where the second application data is updated according to first application data, and the first application data is updated when the first application runs on the first operating system to perform the function; where the first application data and the second application data are stored in the terminal. By using the solutions, sharing of data of a same application between different systems is more convenient and less time-consuming.
Abstract:
Embodiments of the present invention disclose a terminal device. The terminal device includes a periscope lens. The periscope lens includes a filter, a reflective prism module, a zoom lens, and a sensor, where the filter is configured to filter a light ray transmitted from the outside, and the reflective prism module is configured to reflect twice the light ray into the sensor in combination with the zoom lens, where the light ray is obtained after the filtering by the filter. According to the terminal device in the present invention, a limitation on a thickness of the periscope lens imposed by a width of the sensor can be reduced.
Abstract:

Abstract:
Embodiments of the present invention disclose a data transmission method and a device, and belong to the field of communications technologies. In one embodiment, the method includes: sending a broadcast message, where the broadcast message carries information about a sending window that is allocated for a data receiving terminal and that is used to send a trigger message, and the trigger message sending window includes at least one sending opportunity used by the data receiving terminal to send the trigger message; receiving the trigger message sent by the data receiving terminal, and allocating, for the terminal sending the received trigger message, a channel resource used to receive data; and returning channel resource allocation information to the terminal sending the received trigger message, and sending, by using the allocated channel resource, the data to the terminal sending the received trigger message.
Abstract:
Embodiments disclose a base of a cordless digital telephone set and a cordless digital telephone set. In the base of a cordless digital telephone set, a subscriber circuit module and a Bluetooth module can establish, under control of a main control module, a communications channel for direct interconnection, thereby reducing workload of the main control module, and optimizing a transmission path of voice data. The base of a cordless digital telephone set in embodiments of the present invention includes a switch module. When receiving a first control signal that is sent by the main control module, the switch module connects a communication data output pin of the subscriber line interface circuit module to a communication data input pin of the Bluetooth module; and connects a communication data input pin of the subscriber line interface circuit module to a communication data output pin of the Bluetooth module.
Abstract:
An authentication processing method, a processor of a wireless network device, and the wireless network device. The method includes receiving, by a wireless network device, a network access request sent by a user equipment; and if the wireless network device determines, according to the network access request, that the user equipment meets a set condition, performing authentication on the user equipment using a password-free authentication manner, or assigning permission, which is corresponding to the set condition, on a Web administrator page to the user equipment. In embodiments of the present invention, if it is determined that a user equipment meets a set condition, authentication is performed on the user equipment using a password-free authentication manner, and corresponding authentication manners are used according to different user requirements, so that an authentication manner of the wireless network device is more flexible, and network access experience of a user is improved.
