摘要:
A method is implemented in an anchor eNodeB of a network, where the anchor eNodeB communicates with a self-backhauled eNodeB via a radio interface and where the network further includes another eNodeB. The method includes determining whether a user equipment (UE) is being handed off from the first self-backhauled eNodeB to the other eNodeB. The determining is based on: receiving (820) a message from the self-backhauled eNodeB via the radio interface instructing the anchor eNodeB to stop delivering packets that are destined for the UE, or sniffing (1 105, 1 1 10, 1 1 15) into one or more messages sent from the self-backhauled eNodeB to the other eNodeB to identify that the UE is being handed off from the self-backhauled eNodeB to the other eNodeB. The method further includes storing (1 120), based on the determination of whether the UE is being handed off, received packets intended for the UE: and forwarding (1 120) the stored packets to the other eNodeB via a transport network for delivery to the UE.
