摘要： This application provides a data transmission method and apparatus. The method includes: obtaining significant bits in an N th data frame, where N is an integer greater than or equal to 1, a quantity of the significant bits in the N th data frame is smaller than a quantity of bits in the N th data frame, and remaining bits other than the significant bits in the N th data frame are insignificant bits in the N th data frame; and sending the significant bits in the N th data frame, and skipping sending the insignificant bits in the N th data frame. In this way, on a premise of ensuring voice intelligibility, a transmit end apparatus transmits only the significant bits, to minimize a data transmission amount, thereby improving transmission reliability and coverage.

摘要： A data processing method and a related apparatus are disclosed, to improve data recovery effects in various packet loss scenarios. The method includes: determining a packet loss scenario type corresponding to a first data packet when detecting that the first data packet is lost in a data packet transmission process (201); generating a second data packet based on a data packet adjacent to the first data packet if the packet loss scenario type corresponding to the first data packet meets a data packet compensation condition (202); and finally adding the second data packet to a corresponding target location at which the first data packet is located before the first data packet is lost, that is, using the second data packet to compensate for the lost first data packet (203).

摘要： This application provides a method for obtaining an identifier of a terminal device, and a network element. The method includes: obtaining, by a first network element, first information that carries location information of a first terminal device, and determining an identifier set based on the first information, where the identifier set includes an identifier of the first terminal device, and specifically communication information of the first terminal device can be obtained based on the identifier of the first terminal device; sending, by the first network element, a request to a second network element based on each identifier in the identifier set, to determine location information of a terminal device corresponding to the identifier, so that the first network element can obtain location information of the terminal device corresponding to each identifier in the identifier set; and comparing the location information of the first terminal device with the location information of the terminal device corresponding to each identifier in the identifier set to obtain the identifier of the first terminal device. According to the technical solutions provided in this application, the identifier of the terminal device can be obtained based on the location information of the terminal device.
