Abstract: Embodiments of this application disclose a session establishment method, a data transmission method, and a related apparatus. A first device receives a first message sent by a second device. The first device establishes a first session with a third device based on the first message. The first message carries a first identifier and a second identifier, and the second identifier indicates information about a group to which the first identifier belongs. A fourth device is determined based on the second identifier. This improves fourth device determining efficiency, thereby improving data transmission efficiency.

Abstract: Example methods and apparatus for determining a timing advance are described. One example method includes obtaining ephemeris information of a satellite, where the ephemeris information includes coordinates of the satellite and an ephemeris error of the satellite. A timing advance is determined according to a preset rule based on the ephemeris information and location information of a terminal device, where the location information includes coordinates of the terminal device and a positioning error of the terminal device. The preset rule is determined by using a first horizontal distance, a first vertical distance, the ephemeris error, and the positioning error.

Abstract: A photographing method and an electronic device are provided, so that a to-be-photographed target can continue to be tracked after the to-be-photographed target returns to a shooting image, to improve accuracy of focusing performed during photographing of a moving object. The method includes: displaying a first image including a first object and a tracking indicator that is associated with the first object, the tracking indicator indicating that the first object is a tracked target; displaying a second image that does not include the first object or the tracking indicator; displaying a third image including the first object; automatically setting the first object as the tracked target and displaying the tracking indicator associated with the first object; and automatically focusing on the first object when displaying the third image.

Abstract: Communication methods and apparatuses to reduce a transmission delay of a multicast message are described. A first radio access network device receives a first message from a terminal device on a radio bearer or a first message from a second radio access network device. The first radio access network device multicasts the first message through a first air interface.

Abstract: This application provides a channel encoding method, an encoding apparatus, and a system. A bit sequence X1N is output by using X1N=D1N FN, where D1N is a bit sequence obtained after an input bit sequence u1N is encoded based on locations of K to-be-encoded information bits in an encoding diagram that has a mother code length of N, u1N is a bit sequence obtained based on the K to-be-encoded information bits, and FN is a Kronecker product of log2 N matrices F2. In the foregoing technical solution, in particular, a design considers that the locations of the K to-be-encoded information bits in the encoding diagram that has a mother code length of N include a row location index set H of the information bits in the encoding diagram and a layer location index set M of the information bits in the encoding diagram, where 0≤H≤N, and 0

Abstract: This application provides a method and an apparatus for generating road network data of an intersection area, and the intersection area connects a plurality of roads. The method includes: obtaining data of a road link of each of the plurality of roads, where the road link includes an entry link and an exit link; calculating coordinates of an intersection point of an extension line of the entry link of each road and an extension line of an exit link of a neighboring road based on the data of the road link of each of the plurality of roads, where the coordinates of the intersection point are coordinates of an intersection node; and the neighboring road is a road counterclockwise adjacent to the road; or the neighboring road is a road clockwise adjacent to the road, where two intersection nodes in sequence are endpoints of an intra-intersection link.
