A method, an apparatus, and a system for establishing a bearer are provided. The method includes: after a core network node initiates a bearer setup request, receiving, by a gateway node, a first identifier and a third identifier that are sent by a macro access network node, where the first identifier is used to enable the core network node to identify uplink user data forwarded by the gateway node, and the third identifier is used to enable a first small access network node to identify downlink user data forwarded by the gateway node; and sending, by the gateway node, a second identifier and a fourth identifier to the macro access network node, so that the macro access network node sends the second identifier to the first small access network node and sends the fourth identifier to the core network node, where the second identifier is used to enable the gateway node to identify uplink user data sent by the first small access network node, and the fourth identifier is used to enable the gateway node to identify downlink user data sent by the core network node. |
