A cooperative communication method includes determining bandwidth of a first wireless network that user equipment (UE) currently accesses, determining bandwidth required by data to be sent to the UE, and when the bandwidth of the first wireless network cannot meet the bandwidth required by the to-be-sent data, sending a first part of data packets to the first wireless network, and sending a second part of the data packets to at least one core network, so that the at least one core network sends the second part of the data packets to the UE using at least one wireless network, where a communications protocol of the first wireless network is different from that of the at least one wireless network. Bandwidth resources can be integrated on wireless networks with different communications protocols, so that fluent transmission of data can be implemented.
