Step2, in judged result for, in the case of being, startup to be reordered and ignore function certainly.

Here user equipment side when PDCP STATUS REPORT are reported to network side, reorder from suddenly by triggering stopping Function is omited, further, user equipment side carries out self-inspection, i.e. according to the PDCP STATUS REPORT inspections for reporting Survey the minimum packet of sequence number in the window that reorders, if for the loss that reports in PDCP STATUS REPORT Again the packet received after PDCP packets, when judged result is for, in the case of being, UE startups are reordered from suddenly Omit function.The method of the data transfer that the embodiment of the present application is provided, in UE sides, by reporting PDCP to network side While STATUS REPORT, UE triggering stoppings are reordered from function is ignored, and solving re-transmission data cannot be by UE The problem being properly received, and then lifting re-transmission data receiver accuracy rate has been reached, and avoid PDCP data from retransmitting waste Effect.

Further, as judged result is yes, i.e. in the window that reorders of current UE, the minimum packet of sequence number is The PDCP packets newly received after all PDCP packets in the PDCP STATUS REPORT for reporting, so In order to avoid packet loss phenomenon, UE control startups are reordered from function is ignored, so as to ensure the number between UE and network side According to efficiency of transmission.

Further, the Step1 in step S602 reports packet data convergence state report PDCP to network side During STATUS REPORT, stopping is reordered the step of function is ignored to be included：

Step1, judges the corresponding sequence number of clear position reordered in window, if for PDCP STATUS REPORT In the sequence number PDCP SN of PDCP packets that do not receive；

Step2, when judged result is to be, keeps stopping to reorder certainly and ignores function.

Specifically, with reference to Step1 and Step2, if the reordering gap reordered in window of UE are belonging to PDCP The PDCP SN not received in STATUS REPORT, then UE holding stoppings are reordered and ignored certainly.

It is assumed that in PDCP STATUS REPORT, the sequence number PDCP SN of the PDCP packets not received is： The PDCP packets of sequence number 3 and sequence number 4, if the now clear position reordering gap reordered in window of UE The PDCP packets of sequence number 3 and sequence number 4 are there is also, now UE holdings stopping is reordered and ignored certainly.

Further, it is preferable to, the Step1 in step S602 reports packet data convergence state report to network side During PDCP STATUS REPORT, stopping is reordered the step of function is ignored to be included：

Step3, judges to reorder according to the sequence number of the PDCP packets not received in PDCP STATUS REPORT Whether there is corresponding clear position in window；

Step4, when judged result is to be, keeps stopping to reorder certainly and ignores function.

Specifically, it is different from the stopping in above-mentioned steps S602 in Step1 and Step2 to reorder from the condition for ignoring function, There is the condition that another kind can be realized stopping reordering from function is ignored in Step3 and Step4, i.e., it is assumed that PDCP The sequence number of the PDCP packets not received in STATUS REPORT can be：Sequence number 6, sequence number 7 and sequence number 8 PDCP packets, and there is no the PDCP data of sequence number 6, sequence number 7 and sequence number 8 in the window that reorders of UE Bag, illustrates that UE has the possibility of the PDCP packets for losing sequence number 6, sequence number 7 and sequence number 8, in order to avoid packet loss, UE sides first keep stopping to reorder, and oneself ignores function.

To sum up, Fig. 8 is a kind of flow chart of the method for data transfer according to another embodiment of the present invention, as shown in figure 8, With reference to above-mentioned steps S602 to step S606, when the method for data transfer of the embodiment of the present application offer is realized, user The method that the data transfer of the embodiment of the present application offer is realized in equipment side especially by following steps：
