Abstract

In one embodiment, the method includes if a first network device having a first path with a second network device determines that a terminal device is to be handed over from the second network device to a third network device, establishing a second path between the first and third network devices; disabling data transmission for the terminal device via the first path; transmitting a handover indication to the second network device to cause it to suspend transmission of buffered data to the terminal device and to transmit remaining data to the third network device; and upon receiving a completion indication from the second network device that transmission of the remaining data is complete, enabling data transmission for the terminal device via the second path.
