Specific embodiment
For in the prior art, judging operating system brought by each data cell time-out using timer is abandoned
Load is big and inefficient problem, present inventor have discovered that illustrating that the next superframe of LTE standard includes 1024 in LTE protocol
Frame, a frame includes 10 subframes, and therefore, the range of sub-frame number (hereinafter referred to as subframe numbers) is [0-10239], a superframe
In altogether include 10240 subframes.And the interval time in a superframe between two neighboring subframe is fixed 1 millisecond
(ms), it is therefore possible to use subframe numbers realize the function of abandoning timer, the present inventor will be based on son in embodiment below
Frame number abandons the function of timer to realize in the prior art, to complete data processing method provided by the present invention embodiment
And device.
The embodiment of the present invention realized based on LTE standard subframe interrupt function as abandon timer discardtimer,
As described above, between two adjacent sub-frames interval time be fixed 1ms, then the present inventor using such 1ms time between
Every progress " interruption ", by using the subframe numbers of LTE as time value come whether overtime to detect current data cell.Work as PDCP
Layer receives PDCP SDU from upper layer, and subframe numbers and PDCP SDU phase are shut away, this subframe numbers is exactly to be associated with to PDCP SDU
One for detecting whether time-out time tag；This time tag is exactly the time of discardtimer time-out, below
Illustrate the calculation of this time tag, introduces the time of discardtimer time-out, discardtimer first
The time of time-out can be determined using formula (1):
Time=current time+timer timing value (1) of time-out；
Now by the time conversion in formula (1) at subframe numbers, wherein the unit of timer timing value is generally ms, then public
Formula (1) can be transformed into formula (2):
Time (ms)=(current subframe %10240 × 1 (the ms)+timer timing value (ms)) of time-out
(2)；
Since subframe numbers to 10240 can be reversed to 0, so needing to rem (%) operation to 10240 in formula (2)；
The time of time-out and timer timing value can be indicated that is, formula (2) can be transformed into public affairs using sub-frame number below
Formula (3):
Time tag=(current subframe number+timing numerical value) %10240 (3) of time-out；
Wherein the timing numerical value is numerical value corresponding to timer timing value, i.e. timing numerical value is equal to timer timing value
Divided by 1 millisecond, and the time tag of time-out is equal to the time of time-out divided by 1 millisecond；.
SDU has been handled generation PDU by PDCP, is delivered to rlc layer, and logically channel is stored in oneself queue to rlc layer
In.When each subframe, which is interrupted, to be occurred, checked in each logical channel buffer queue of RLC in the processing routine that subframe is interrupted
Data cell (PDCP PDU) associated time tag；If current subframe numbers do not reach or are not above time mark
Label, then it is assumed that the PDCP PDU is not timed-out, and does not need to abandon；Due to the succession of queue, the data after the data just do not have
Necessity detects whether time-out again.If current subframe numbers meet or exceed the time tag, then it is assumed that time-out simultaneously needs to lose
The data are abandoned, then detect next data again.
Time-out is also required to the case where considering subframe numbers reversion, since the maximum timing value of agreement regulation discardtimer is
1500ms, thus in case of time tag reversion and current subframe number not yet invert the case where, when current subframe number can compare
Between label it is much larger, be far longer than 1500.So the formula (4) that judgement is not timed-out is as follows:
(time tag>current subframe number) or ((time tag<current subframe number) and ((current subframe number-time mark
Label) > 1500)) (4)；Time tag in formula (4) is the time tag of the time-out in formula (3),；The present invention is implemented
Example is only interrupted using subframe and is used as timing mechanism, the function that a large amount of timers can be replaced to complete along with associated overtime label
Can, therefore, technical solution provided in an embodiment of the present invention can reduce the load of operating system, and have and be concisely and efficiently
