Abstract:
Embodiments of the present application relate to the communications field, and provide a bearer establishment method and apparatus, and a system. The method includes: sending, by an eNB, a first request message to an MME in a handover process of UE; determining, by the MME, a target SGW and a target PGW of the UE based on the first request message; requesting, by the MME, the target SGW to establish a first bearer between the target SGW and the target PGW for the UE; and after the first bearer is established, requesting, by the MME, a source eNB to release a radio bearer and delete a second bearer on the source side. In the present application, a process of establishing the first bearer and the cell handover process are completed in parallel, so that the terminal can perform communication through the first bearer after a cell handover.
