Actual duration due to new resequencing timer is less than setting duration corresponding to described new resequencing timer, thus shorten during resequencing timer runs the rearrangement time received again in out of order PDU situation, improve recombination efficiency, reduce content expense, shorten to the upper strata data delivery bag time.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
As shown in Figure 1, the method that the embodiment of the present invention one starts resequencing timer duration comprises the following steps:
Step 101, after receiving out of order PDU, judge currently whether have the resequencing timer run;
Step 102, determining currently have the resequencing timer run, and current resequencing timer then after, start new resequencing timer;
Wherein, the actual duration of described new resequencing timer is less than setting duration corresponding to described new resequencing timer.
The embodiment of the present invention, after resequencing timer run duration receives out of order PDU, shortens the actual duration of the next resequencing timer started, thus shortens during resequencing timer runs the rearrangement time received again in out of order PDU situation.
Preferably, determining currently have the resequencing timer run, and current resequencing timer then after, before starting new resequencing timer, first determine whether the out of order PDU do not received, after defining the out of order PDU do not received, start new resequencing timer.
In force, when determining the actual duration of described new resequencing timer, in the moment of the out of order PDU that can receive for the last time according to resequencing timer run duration, determine the actual duration of described new resequencing timer.
Concrete, determine the moment of the out of order PDU that current resequencing timer run duration receives for the last time;
According to the described moment determined, determine the actual duration of described new resequencing timer.
It should be noted that, according to the moment of the out of order PDU that current resequencing timer run duration receives for the last time, determine that the actual duration of described new resequencing timer just illustrates.In the moment of any once out of order PDU that the embodiment of the present invention can receive according to current resequencing timer run duration, determine the actual duration of described new resequencing timer.
Concrete mode and the moment of the out of order PDU received for the last time according to current resequencing timer run duration, determine that the mode of the actual duration of described new resequencing timer is similar, do not repeat them here.
Preferably, according to the described moment determined, determine the duration between described moment and current resequencing timer are then;
Setting duration corresponding for described new resequencing timer is poor with the described duration determined, if described difference be on the occasion of, using the difference that the obtains actual duration as described new resequencing timer, or the actual duration of described new resequencing timer is not less than the described difference that obtains and is less than setting duration corresponding to described new resequencing timer.
In force, if described difference is non-positive value, then using the actual duration of setting duration corresponding for described new resequencing timer as described new resequencing timer.
In force, if the setting duration that described new resequencing timer is corresponding equals setting duration corresponding to current resequencing timer, the moment started in the described moment determined and current resequencing timer is poor, using the difference that the obtains actual duration as described new resequencing timer, or the actual duration of described new resequencing timer is not less than the described difference that obtains and is less than setting duration corresponding to described new resequencing timer.
The setting duration that resequencing timer is corresponding can set as required.Can specify in the protocol; Also can be notified by high level, as by RRC(Radio Resource Control, wireless heterogeneous networks) be configured.
The embodiment of the present invention adjusts the length of resequencing timer when the resequencing timer for a rear out of order PDU starts, deduction falls the time that this out of order PDU waits for previous resequencing timer, be the time of reception of the out of order PDU of the time of reception-previous triggering resequencing timer of a rear out of order PDU, thus shorten in this case meaningless time waste rationally and effectively, the PDU that to avoid therefore accumulation below more etc. to be reorganized, improve recombination efficiency, reduce EMS memory occupation.
Figure below is identical with the setting duration that each resequencing timer is corresponding, and the UMPDU of SN=1, SN=3 and SN=5 is out of order to be described for the scheme of example to the embodiment of the present invention.
As shown in Figure 2, to the time of reception of out of order PDU, to eat dishes without rice or wine, time point is as the criterion, scope 0 ~ 10239ms.
Put into when there being new PDU and receive buffer(buffer memory) time, judge whether it is out of order PDU, if (VR (UH) represents a rear SN of the highest SN in the current PDU received to VR (UH) >VR (UR), VR (UR) represents minimum but still at the SN seeking the UMD PDU reset, and upgrade after timer expiry, VR(UX) represent the rear SN of SN of the PDU triggering resequencing timer; VR (UH) >VR (UR), namely determines it is out of order PDU), judge that whether resequencing timer is in operation further:
When receiving the PDU of SN=1 in Fig. 2, resequencing timer does not also run, and the PDU due to SN=1 is out of order PDU, at this moment starts resequencing timer, and the initial time of recording timer, be also the time of reception point t1 of the out of order PDU of SN=1;
Suppose, at this resequencing timer run duration, to receive again the out of order PDU of SN=3, now judge that resequencing timer is in operation, the time of reception point t3 of the out of order PDU of record SN=3.
When the resequencing timer time-out of the out of order PDU for SN=1, the rearrangement of first out of order PDU after for last unreceived PDU before VR (UH) will be started, the actual duration of new resequencing timer that this programme is determined is the duration that before the setting duration of the resequencing timer of RRC configuration deducts VR (UH), last unreceived PDU PDU below waits for resequencing timer time-out, and the duration that the instantiation for upper figure is t3-t1 is exactly the new actual duration of resequencing timer.
That is, when also not receiving the PDU of SN=0 in Fig. 2, the out of order PDU(time of reception point receiving SN=1 represents with t1), start resequencing timer t-reordering(and suppose that the setting duration of RRC configuration resequencing timer is 50ms);
At resequencing timer run duration, the out of order PDU(time of reception point receiving again SN=3 represents with t3), assuming that and the PDU time of reception point interval 2ms of SN=1;
The embodiment of the present invention: when the resequencing timer time-out of the out of order PDU for SN=1, start the resequencing timer for current SN=3, the actual duration of the resequencing timer of SN=3 be the setting duration-VR (UH) of the resequencing timer of RRC configuration before last unreceived PDU PDU below wait for the duration of resequencing timer time-out, i.e. actual duration=50-(50-(t3-t1))=t3-t1=2ms of the resequencing timer of SN=3.
Suppose that the resequencing timer run duration at the out of order PDU for SN=1 receives again the out of order PDU of SN=5, see Fig. 3.Now judge that resequencing timer is in operation, the time of reception point t5 of the out of order PDU of record SN=5, also have out of order PDU if follow-up, by that analogy.
When the resequencing timer time-out of the out of order PDU for SN=1, the rearrangement of first out of order PDU after for last unreceived PDU before VR (UH) will be started, the actual duration of the new resequencing timer that this programme is determined is the duration that before the setting duration of the resequencing timer of RRC configuration deducts VR (UH), last unreceived PDU PDU below waits for resequencing timer time-out, and the duration that the instantiation for upper figure is t5-t1 is exactly the new actual duration of resequencing timer.
That is, when also not receiving the PDU of SN=0 in Fig. 2, the out of order PDU(time of reception point receiving SN=1 represents with t1), it is 50ms that startup resequencing timer t-reordering(supposes that RRC configures this timer length);
The embodiment of the present invention: when the resequencing timer time-out of the out of order PDU for SN=1, start the resequencing timer for current SN=5, the actual duration of the resequencing timer of SN=5 be the setting duration-VR (UH) of the resequencing timer of RRC configuration before last unreceived PDU PDU below wait for the duration of resequencing timer time-out, i.e. actual duration=50-(50-(t5-t1))=t5-t1=4ms of the resequencing timer of SN=5.
As shown in Figure 4, the method for the embodiment of the present invention four point writing time comprises:
Step 401, define new PDU put into receive buffer.
Step 402, upgrade state variable (namely upgrading VR(UH) and VR(UR)).
Step 403, according to upgrade after state variable, judge whether new PDU is that namely out of order PDU(judges VR(UH) whether be greater than VR(UR)), if so, then perform step 405, otherwise, perform step 404.
The new PDU that step 404, basis receive, carries out PDU restructuring, and jumps out this flow process.
Step 405, judge whether resequencing timer runs; If so, then step 406 is performed; Otherwise, perform step 407.
Step 406, judge whether the previous PDU of new PDU does not receive and (namely judged by SN, the SN of such as new PDU is M, then the SN of previous PDU is M-1, if do not receive previous PDU, then determine that new PDU is last the out of order PDU be currently received), if so, then step 408 is performed; Otherwise jump out this flow process.
Step 407, record resequencing timer start-up time, and start resequencing timer, the actual duration of resequencing timer is the setting duration of the resequencing timer of RRC configuration, and jumps out this flow process.
The time point that step 408, record record before receiving the time point covering of new PDU, and jump out this flow process.
Concrete, if before writing time point, the time point of record before the time point receiving new PDU is covered, if before non-writing time point, then the time point of record before the time point that record receives new PDU covers.
As shown in Figure 5, the method that the embodiment of the present invention five starts resequencing timer comprises:
Step 501, determine resequencing timer time-out.
Step 502, carry out PDU restructuring.
Step 503, judge whether that namely the out of order PDU(do not received in addition judges VR(UH) whether be greater than VR(UR)), if so, then perform step 504, otherwise, jump out this flow process.
Step 504, start resequencing timer, duration is the difference between moment of starting of moment of the out of order PDU that current resequencing timer run duration receives for the last time and previous resequencing timer.
