    Abstract: A method and an apparatus for signal synchronization are disclosed. The method for signal synchronization includes: A self-synchronizing first terminal device broadcasts first synchronization information, determines whether the first terminal device and a second terminal device have implemented signal synchronization when receiving second synchronization information sent by the second terminal device, and determines, based on a determining result, whether to synchronize with the second terminal device. This reduces a probability of communication interruption caused by synchronization source switching by the first terminal device after the second terminal device performs synchronization by using the first terminal device as a synchronization source. The method for signal synchronization may be applied to scenarios such as the intelligent driving, intelligent connected vehicles, and internet of vehicles.

    Abstract: An image correction terminal provided starts a camera, to enter a default shooting mode; the terminal previews a photographed object, to obtain a preview image; the terminal determines, based on the preview image, whether the photographed object is of a document type; and the terminal corrects a photographed object image when the photographed object is of the document type, where the photographed object image is an image obtained after the photographed object is photographed. As a result, the terminal can effectively detect a scene type, and avoid system power consumption caused due to frequent detection of a type of the photographed object.

    Abstract: Embodiments of the present invention relate to a method for obtaining radio capability information of a terminal, a core network entity, a base station, and a terminal. When a first terminal changes from a first communication path for the first terminal to directly access a network to a second communication path for the first terminal to access the network by using a second terminal, the first terminal receives a first message that is sent by a base station to obtain radio capability information of the first terminal; and then sends the radio capability information of the first terminal to the base station, where the radio capability information includes information about a manner of connection between the first terminal and the second terminal and identification information of the second terminal.

    Abstract: An inter-network interworking method, an apparatus, and a system are provided, and relate to the field of communication technologies, to ensure that a service is not interrupted when a terminal moves from a second network to a third network. The method includes: When the terminal supports a NAS capability of the third network and/or a network name corresponding to the terminal supports interworking between the second network and the third network, a second access management network element sends a session management request including a session identifier to a first session management network element that supports interworking of the terminal among a first network, the second network, and the third network. The second access management network element receives, from the first session management network element, a session management response including a session context of the terminal in the third network. According to the method, the session context of the terminal in the third network can be prepared in advance when the terminal accesses the second network, so that it is ensured that the service is not interrupted when the terminal subsequently moves from the second network to the third network.
