Embodiments of the present invention provide a method for a handover without a default bearer and a device, relate to the field of communications, and solve an issue that when there is no default bearer in an evolved packet system, small data is forwarded by using a signal connection when user equipment is handed over between cells. The method thereof is: A first network device sends a relocation request to a second network device, the second network device establishes a connection to a third network device indicated by the relocation request, and sends a response to the first network device and indicates that data is to be sent by using a signaling plane, and then the first network device instructs a source network device to forward the data to a target network device according to a forwarding mode indicated by a handover command; or after the second network device establishes the connection to the third network device indicated by the relocation request, the third network device caches data, and after a handover of user equipment is completed, the third network device sends the cached data to the second network device. The embodiments of the present invention are applied to cell handovers without a default bearer. |
