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

    Abstract: The present invention provides a method and an eNB for reactivating semi-persistent scheduling. The method comprises: an eNB (2) where the semi-persistent scheduling is activated storing size information of a pre-allocated transport block after pre-allocating resources to a UE (1); and after receiving a complete semi-persistent scheduling data packet uploaded by the UE (1), the eNB (2) comparing the size of the data packet with the size of the pre-allocated transport block stored in the eNB (2) and reactivating the semi-persistent scheduling according to the comparison result. The eNB (2) comprises a storage module, a resource allocation module, a data packet receiving module and a comparing module. The present invention solves the problem that the eNB can not reactivate the uplink SPS when both SPS services and dynamic scheduling services exist and are divided into UEs in the same LCG and uplink SPS data changes in a period of time, causing allocation of air interface resources to be more reasonable.

    Abstract: A data transmission scheduling method, device and system are disclosed, which relates to the field of wireless communications, and solves the problem of low network utilization rate in the related scheduling modes. The method includes: receiving a measurement report sent by an access point (AP), wherein the measurement report carries a transmission power of the AP sending the measurement report, and signal reception levels and powers of surrounding devices of the AP; according to the measurement report, evaluating interference relationships between the AP and the surrounding devices of the AP, and obtaining an evaluation result; and making a scheduling decision according to the evaluation result. The technical scheme provided in the embodiments of the present invention is applicable to a WLAN, which implements parallel communication of a plurality of low-interference terminals.

    Abstract: The disclosure discloses a method and a system for synchronizing an Access Stratum (AS) security algorithm. The method comprises: a control plane notifying a user plane to start a decryption exception detection when sending an Radio Resource Control (RRC) connection re-establishment message (100); the user plane performing the decryption exception detection on a service message received after the RRC connection re-establishment, and sending a decryption exception instruction to the control plane when discovering the decryption exception of the service message (101); and the control plane performs a corresponding exception process according to the decryption exception instruction (102). With the method, the exception of the AS security algorithm configured for User Equipment (UE) in the RRC connection re-establishment is discovered in time, the bandwidth waste caused by invalid data packets of an air interface is maximally avoided, and the prompt exception recovery is improved, so as to further improve the user experience before and after a handover.
