The present invention discloses a data transmission method, a base station, a user equipment, and a communications apparatus. The method includes: receiving, by a base station, a first transmission request message that is sent by a UE and requests to send data to the base station by using a first bearer of a first hotspot cell, where the first transmission request message carries an identifier of the first bearer and an identifier of the first hotspot cell; sending, by the base station, a first transmission response message in response to the first transmission request message to the UE; and receiving, by the base station, the data that is sent, after the UE receives the first transmission response message, by the UE by using the first bearer of the first hotspot cell. According to the data transmission method, the base station, the user equipment, and the communications apparatus in embodiments of the present invention, the base station can learn that data transmitted from a hotspot cell belongs to the UE, which can ensure that a subsequent related service is not interrupted when the UE leaves the hotspot cell, thereby improving user experience. |
