Abstract: This application provides a data transmission method and apparatus. The method includes: obtaining significant bits in an Nth data frame, where N is an integer greater than or equal to 1, a quantity of the significant bits in the Nth data frame is smaller than a quantity of bits in the Nth data frame, and remaining bits other than the significant bits in the Nth data frame are insignificant bits in the Nth data frame; and sending the significant bits in the Nth data frame, and skipping sending the insignificant bits in the Nth data frame. According to the application, 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.

Abstract: A method of bearer deletion is provided to improve the universality of the bearer deletion process. The method includes: receiving, by the original intermediate NE, the cancellation type indication parameter sent by the HSS, and deleting the bearer between the serving gateway (S-GW) and a packet data network gateway (P-GW), if the original intermediate network element obtains an attach type according to the cancellation type indication parameter indicating an attach type and a corresponding bearer exists on the original intermediate NE. This method helps efficiently improve the universality of the bearer deletion flow.
