Bearer shunting method for backhaul link and network device

Provided are a bearer shunting method for a backhaul link and a network device. The method comprises: determining, by a first network device, a bearer to be shunted on a main backhaul link; sending, by the first network device, a bearer shunting request message to a second network device; receiving, by the first network device, bearer shunting acknowledgement information sent by the second network device; determining, by the first network device, a target shunting bearer in the bearer to be shunted according to information about the target shunting bearer, and determining auxiliary backhaul link configuration information according to the information about the target shunting bearer and first configuration information; sending, by the first network device, the auxiliary backhaul link configuration information to a third network device; and switching, by the first network device, service data on the target shunting bearer onto a second auxiliary backhaul link. By means of the technical solution of the present invention, when user data amount is large, data on a target shunting bearer of a main backhaul link is shunted onto an auxiliary backhaul link, thereby reducing the load of the main backhaul link and satisfying the QoS demands of user services.
