Abstract: An embodiment of the present application relates to the field of communication technologies, and particularly to a data offloading method and a gateway, for achieving data offloading and relieving pressure on a core network. The data offloading method according to the embodiment of the present application is applied to a long term evolution (LTE) system including a base station, a gateway, a core network, and a local server, wherein the base station establishes a link with the core network via the gateway and the base station establishes a link with the local server via the gateway. The method comprises: a gateway receives a first data packet transmitted by a base station, wherein the first data packet comprises first data; and the gateway transmits the first data to a local server upon determining that the first data packet is not a VoLTE data packet in an LTE system, thereby achieving offloading of non-VoLTE data and thus relieving the pressure on a core network.

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.
