This application relates to the field of mobile communications, and in particular, to a technical solution of sharing data with a nearby device by using a wireless communications technology. In a method for printing a photo, a mobile phone first selects a to-be-printed photo, then discovers a nearby device by using the foregoing related wireless communications technology, and displays the discovered device such as a printer or a projector on the mobile phone; and then a user performs a tap operation on the discovered printer, so that one-tap printing can be implemented. In this way, printing efficiency of an electronic device is improved, and user experience is also improved.

Data sharing method, graphical user interface, electronic device, and system

An image recognition method and a terminal, where the method includes obtaining, by the terminal, an image file comprising a target object, recognizing, by the terminal, the target object based on an image recognition model in the terminal to obtain object category information of the target object, and storing, by the terminal, the object category information as first label information of the target object. Hence, image recognition efficiency of the terminal can be improved, and privacy of a terminal user can be effectively protected.

Image recognition method and terminal

A device and method providing audio-based, continuous authentication of a user to provide access to a processing device. A user echoprint model is created while a user interacts with an authentication interface for another authentication method of the device, transparently to the user. The sound waves are user-specific and inaudible. The user-specific sounds are reflected by the user and used to construct an echoprint which can be compared by a previously constructed user-specific, echoprint model. If the result is positive, access to the processing device may be allowed. Access to the processing device is based on the audio authentication or the alternative authentication is based on the result of audio authentication and updates a device state indicating whether the display is on or off and whether the device is locked or unlocked.

Echoprint user authentication

An image recognition method and a terminal, where the method includes obtaining, by the terminal, an image file including a target object recognizing, by the terminal, the target object based on an image recognition model in the terminal using a neural network computation apparatus in the terminal to obtain object category information of the target object, and storing, by the terminal, the object category information in the image file as first label information of the target object. Hence, image recognition efficiency of the terminal can be improved, and privacy of a terminal user can be effectively protected.

Embodiments of the present invention provide a service allocation method and apparatus. The method includes: firstly, generating, by a core network side device, a first dedicated network identifier according to an association relationship sent by user equipment UE, where the first dedicated network identifier is used to identify the association relationship; secondly, sending, by the core network side device, the first dedicated network identifier to the UE; receiving, by the core network side device, a service request message sent by the UE; and finally, allocating a service to the UE according to the service request message and the first dedicated network identifier. Because each wireless router has a unique first dedicated network identifier, the core network side device can provide, according to the first dedicated network identifier, a targeted service or tariff policy for UE corresponding to each wireless router.

An embodiment power control method includes obtaining, by a base station, a bit error rate (BER) of a physical uplink control channel (PUCCH) of a UE at a subframe i, and sending a transmit power control command &#x3b4;'(i&#x2212;k) having a value related to a transmit power control command obtained by the base station at a subframe i&#x2212;kand that is determined according to the relationship of the BER to a bit error rate reference value. An embodiment base station includes a second obtaining unit configured to obtain a BER of a PUCCH of a UE at a subframe i and a second sending unit configured to send a transmit power control command &#x3b4;&#x2032;(i&#x2212;k) having a value related to a transmit power control command obtained by the base station at a subframe i&#x2212;kand that is determined according to the relationship of the BER to a bit error rate reference value.

Power control method and base station

A power control method and a base station are disclosed. The method includes obtaining, by a base station, IN(i). The IN(i) is an average interference noise power of a physical uplink control channel (PUCCH) carried by radio resources that are allocated by the base station at a subframe i. The base station sends a parameter P(i) for power control at the subframe i.

The invention discloses a pilot synchronization channel structure for mobile communication systems. The channel structure includes a pilot channel overlapping a synchronization channel (SCH), defined in the wideband code division multiple access (WCDMA) protocol. Each frame of the pilot channel consists of plural time slots. Each time slot is packed with pre-selected pilot symbols, after spread spectrum and scrambling. The overlap can be defined as search code of one symbol length with pilot signal of m&#x2212;1 symbols length by intermittent overlap. The overlap can also be defined as search code of one symbol length with pilot signal of m symbols length by continuous overlap. The invention combines organically both CDMA 2000 and WCDMA standards to provide better pilot and synchronization functions.
