Abstract: The present application discloses a switch supporting method comprising: an eNB sends a path switching request message to an MME to notify the MME of information on a bearer remaining unchanged; the MME reserves the bearer remaining unchanged and does not trigger a deactivation process for the bearer remaining unchanged; the MME sends a modify bearer request message to an SGW. With the present application, data loss can be avoided and service continuity is ensured when a UE moves in a small cell scenario.
