Abstract
The present invention discloses a PDCP state report forming method and a device, and the problem of resource waste caused by forming a PDCP state report in a full configuration scene based on a PDCP radio bearer reconstruction process in the prior art is solved. The PDCP state report forming method comprises a step of receiving a radio resource control (RRC) connection reconfiguration signaling from a network side, a step of analyzing the RRC connection reconfiguration signaling to obtain an analysis result, and a step of determining whether the PDCP state report is formed or not according to the analysis result. According to the scheme, the problem of resource waste caused by forming the PDCP state report in the full configuration scene can be avoided, and the resource utilization rate is improved.
Description
Technical field
The present invention relates to field of mobile communication, particularly relate to a kind of bag PDCP PDCP status report construction method and device.
Background technology
At RRC (RadioResourceControl, radio resource control) connection reconstruction and switching scene under, RRC connects the cell (fullconfig) that entirely can configure mark in reprovision signaling with, now, UE (UserEquipment, subscriber equipment) need release to have whole Radio Resources, and use the RRC received to connect the radio-resource-configuration of carrying in reprovision signaling.The radio bearer that rrc layer is secondary is switched and for reconstruction, PDCP (PacketDataConvergenceProtocol, bag PDCP) level is embodied in the reconstruction to PDCP entity.The effect of PDCP status report is the PDCPPDU (ProtocolDataUnit, protocol Data Unit) avoiding transmitter side repetition transmission and reception side to receive, thus reaches reduction network load, reduces the object of data delay.PDCP status report sends PDCP data as first on Deta bearer after radio bearer reconstruction or switching.Receiver side AM (AcknowledgedMode after reconstruction completes, affirmation mode) SN (SequenceNumber, sequence number) continuity rebuild before state, receiver side to transmitter side condition report feedback as first PDCP data after having rebuild.After this receiver side is according to the status report of transmitter side, continues the transmission of follow-up data, can be avoided unnecessary re-transmission.
RRC connects can with the reconstruction of the radio bearer of the cell of full configuration mark and switching in reprovision signaling, can first rebuild all radio bearers, and when rebuilding PDCP entity, if status report response is set to TRUE, so can generate a status report when rebuilding PDCP.After having rebuild all radio bearers, according to the requirement of fullconfig, the Radio Resource that data surface is all can be discharged, namely whole radio bearers is deleted and rebuild, along with this process, the arm-to-arm public lecture generated in PDCP volume reconstruction process is not only deleted, and the SN of PDCP entity also gets back to initial condition, from 0.Therefore, under the scene of full configuration, the structure carrying out PDCP status report is a unnecessary process with sending, because the status report now built can be released when fullconfig deletes all radio bearer entities.And to build PDCP status report be a complicated process, need the sequence number traveling through PDCP receive window, No. SN that finds out all PDCPPDU do not received completely, then encode according to the status report format of specifying in PDCP agreement.A wherein corresponding status report in a radio bearer, if terminal now has many radio bearers (can reach 8 at most), so to build 8 bar state reports, expense is larger, if construct PDCP status report to delete recovery again when full configuration, then cause the unnecessary wasting of resources.
Summary of the invention
