Abstract
The present invention provides a downlink data transmission method, base station, and serving gateway on an LTE network. The method includes: learning, by an eNB, that a UE needs to be paged, when an S1 bearer is retained and a radio bearer is released; paging, by the eNB, the UE and re-establishing a radio bearer between the eNB and the UE; and sending, by the eNB, downlink data, which is received from an S-GW, to the UE through the re-established radio bearer. Embodiments of the present invention can ensure correct transmission of downlink data, and avoid data loss.
