Abstract
The embodiments of the present application relate to the technical field of communications, and particularly relate to a Voice over Long-Term Evolution (VoLTE) data guarantee method and device, this being used for ameliorating the problem of poor VoLTE call quality caused by poor access network quality. The method involves: a first device receiving at least one group of first data packets sent by a second device; with regard to each group of first data packets in the at least one group of first data packets, executing the operation of the first device carrying out FEC coding on M VoLTE data packets comprised in the group of first data packets to obtain N FEC redundant data packets; adding FEC group information, corresponding to each data packet, to each data packet among the M VoLTE data packets and N FEC redundant data packets; and sending, to a third device, the M VoLTE data packets and N FEC redundant data packets with the FEC group information added thereto. Thus, the VoLTE data packet loss rate of an access network is lowered, and the problem of poor VoLTE call quality, caused by poor access network transmission quality, is ameliorated.
