Processing method and processing system for nondestructive switching of relay node user interfaces

The invention discloses a processing method and a processing system for nondestructive switching of relay node user interfaces. The processing method and the processing system are applied to switching of relay nodes. The processing method includes respectively performing order-preserving process to downlink data packets and uplink data packets corresponding to service users of the relay nodes by a target base station. The processing system comprises a source base station, the target base station, relay nodes and service gateways of the service users of the relay nodes, wherein the source base station is used for forwarding the downlink data packets and the uplink data packets corresponding to the service users of the relay nodes to the target base station, the relay nodes are used for forwarding the uplink data packets of the service users to the target base station, the service gateways are used for sending the downlink data packets of the corresponding service users to the target base station, and the target base station is used for realizing order-preserving process to the received downlink data packets and uplink data packets corresponding to the service users of the relay nodes. By the processing method and the processing system, the data packets of the service users of the relay nodes can be forwarded nondestructively and orderly.
