摘要： The present invention discloses a method and device for reestablishment at packet data convergence protocol (PDCP) layer. On the receiving side of the PDCP layer, the method comprises: clearing resident control messages (501); processing resident service messages, and clearing feedback information generated during processing (502); and resetting a decompressor, and updating configuration of a decryption module (503). On the transmitting side of the PDCP layer, the method comprises: resetting a compressor, and updating configuration of an encryption module; clearing the resident control messages; and reprocessing the resident service messages. With the differentiated processing for the resident messages at the PDCP layer during the reestablishment, the present invention can avoid the abnormal mode switching of the compressor, and accelerate the user plane restoration after the reestablishment. The present invention can further avoid the transmission of invalid feedback, thus improving the utilization of air interface resources; meanwhile, by avoiding the influence of the invalid status report on uplink and downlink transmission policies, the present invention can reduce retransmission of the service messages, thus improving the utilization of air interface resources.

In the present disclosure, the offloading judgment condition, which the offloading device is in accordance with, directly originates from the core network, and the core network can proactively obtain required user information, thus offloading judgment can be made correctly and completely as much as possible, and offloading judgment can be implemented with QoS strategies of the core network together, and there is no need to add new QoS management points being independent of the core network.
