Estimating the term…
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.
A method for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, comprising
A method for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, which is applied to a receiving side of the PDCP layer, comprising:
A method for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, which is applied to a transmitting side of the PDCP layer, comprising:
A device for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, comprising a receiver and a transmitter, wherein
A receiver in a device for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, being configured to clear resident control messages during the reestablishment at the PDCP layer, process resident service messages and clear feedback information generated during the processing.
A transmitter in a device for reestablishment at a Packet Data Convergence Protocol (PDCP) layer, being configured to clear resident control messages during the reestablishment at the PDCP layer.
