Embodiments of the present invention provide a method, an apparatus, and a system for establishing a switch link. The method for establishing a switch link includes: sending a query request message used to query address information of a target Evolved NodeB (eNB) to a network side when no switch link exists between a source eNB and the target eNB; receiving a query response message that includes the address information of the target eNB and is returned by the network side; and sending a link establishment request message according to the query response message that includes the address information of the target eNB, and establishing a switch link. The embodiments of the present invention further provide an apparatus and a system for establishing a switch link. According to the method, the apparatus, and the system for establishing a switch link that are provided in the embodiments of the present invention, when no switch link exists between the source eNB and the target eNB reported by a terminal, the query request message is sent to the network side to obtain the address information of the target eNB, so as to establish a switch link. Therefore, the switch link can be established in the case that an advanced planning does not exist.
