Description

一种数据处理方法及装置、存储介质、用户设备Data processing method and device, storage medium and user equipment 技术领域Technical field
本发明涉及数据处理技术，尤其涉及一种分组数据汇聚协议(PDCP，Packet Data Convergence Protocol)层的数据处理方法及装置、存储介质、用户设备。The present invention relates to data processing technologies, and in particular, to a data processing method and apparatus, a storage medium, and a user equipment of a Packet Data Convergence Protocol (PDCP) layer.
背景技术Background technique
长期演进(LTE，Long Term Evolution)版本(R9，Release 9)36.323协议里说明PDCP层需要实现“基于定时器的丢弃功能(timer based discard)”。当PDCP从上层收到一包PDCP服务数据单元(SDU，Service Data Unit)，就要启动一个丢弃定时器(discard timer)关联到这个PDCP SDU上。而当discard timer超时后，就要丢弃该PDCP SDU以及和其关联的PDCP协议数据单元(PDU，Protocol Data Unit)，如果PDCP PDU已经投递给了底层如无线链路控制(RLC，Radio Link Control)层、媒体接入控制(MAC，Medium Access Control)层、物理层(PHY，Physical Layer)层，则需指示底层将其丢弃。In the Long Term Evolution (LTE) version (R9, Release 9) 36.323 protocol, the PDCP layer needs to implement a "timer based discard". When the PDCP receives a packet of a PDCP Service Data Unit (SDU) from the upper layer, it initiates a discard timer associated with the PDCP SDU. After the discard timer expires, the PDCP SDU and its associated PDCP Protocol Data Unit (PDU) are discarded. If the PDCP PDU has been delivered to the underlying layer, such as Radio Link Control (RLC), Layer, Medium Access Control (MAC) layer, Physical Layer (PHY) layer, you need to instruct the underlying layer to discard it.
PDCP层的最大序号空间为[0-4095]，所以理论上可以缓存这么多个数据单元，但实际情况经常用户设备(UE，User Experiment)第二层(L2，Layer 2)会至少缓存几十上百的数据单元，而每个数据单元启动一个discard timer；对每个数据单元都启动一个discard timer，这对于操作***是非常大的负荷；此外，上层经常会投递一批数据单元过来，这也就意味着这一批数据单元的discard timer几乎是一起启动，超时时也是一起超时；这时，PDCP层就会不停地接收处理这一批超时消息，因此导致PDCP层也是相当地低效。 The maximum sequence space of the PDCP layer is [0-4095], so in theory, it is possible to cache such a plurality of data units, but in reality, the second layer (L2, Layer 2) of the user equipment (UE, User Experiment) will cache at least tens of Hundreds of data units, each data unit starts a discard timer; a discard timer is started for each data unit, which is a very large load on the operating system; in addition, the upper layer often delivers a batch of data units, which This means that the discard timers of this batch of data units are started almost together, and timeouts also time out together; at this time, the PDCP layer will continue to receive and process this batch of timeout messages, thus causing the PDCP layer to be quite inefficient. .

具体实施方式detailed description
使用丢弃定时器来判断每个数据单元超时所带来的操作***的负荷大、以及低效的问题，本发明人发现：LTE协议中说明LTE制式下一个超帧包括1024个帧，一个帧包括10个子帧，因此，子帧序号(以下简称子帧号)的范围是[0-10239]，一个超帧中一共包括10240个子帧。而一个超 帧中相邻两个子帧之间的间隔时间是固定的1毫秒(ms)，因此，可以采用子帧号实现丢弃定时器的功能，本发明人在以下的实施例都将基于子帧号来实现现有技术中丢弃计时器的功能，以完成本发明个实施例所提供的数据处理方法及装置。Using the discard timer to judge the problem of large load and inefficiency of the operating system caused by the timeout of each data unit, the inventors have found that the LTE protocol indicates that the next superframe of the LTE system includes 1024 frames, and one frame includes 10 subframes, therefore, the range of the subframe number (hereinafter referred to as the subframe number) is [0-10239], and a total of 10240 subframes in one superframe. And one super The interval between two adjacent subframes in the frame is fixed by 1 millisecond (ms). Therefore, the function of discarding the timer can be implemented by using the subframe number. The inventors will use the subframe number in the following embodiments. The function of discarding the timer in the prior art is implemented to complete the data processing method and apparatus provided by the embodiments of the present invention.
本发明实施例基于LTE制式子帧中断功能来实现作为丢弃定时器discardtimer，如上所述，两个相邻子帧之间间隔时间是固定的1ms，那么本发明人利用这样1ms的时间间隔进行“中断”，通过将LTE的子帧号作为时间值来来检测当前的数据单元是否超时。当PDCP层从上层收到PDCP SDU，将子帧号与PDCP SDU相关起来，这个子帧号就是给PDCP SDU关联的一个用于检测是否超时的时间标签；这个时间标签就是discardtimer超时的时间，下面来说明这个时间标签的计算方式，首先介绍一下discardtimer超时的时间，discardtimer超时的时间可以采用公式(1)进行确定：The embodiment of the present invention implements the discard timer as a discard timer based on the LTE system subframe interrupt function. As described above, the interval between two adjacent subframes is fixed at 1 ms, and the inventor uses the interval of 1 ms to perform " Interrupt", by detecting the current data unit timeout by using the LTE subframe number as a time value. When the PDCP layer receives the PDCP SDU from the upper layer, the subframe number is associated with the PDCP SDU, and the subframe number is a time label associated with the PDCP SDU for detecting whether the timeout expires; this time label is the time when the discardtimer times out, below To illustrate the calculation of this time stamp, first introduce the time of the discardtimer timeout. The time of the discardtimer timeout can be determined by formula (1):
超时的时间＝当前时间+定时器定时值    (1)；Timeout time = current time + timer timing value (1);
现将公式(1)中的时间换算成子帧号，其中定时器定时值的单位一般为ms，那么公式(1)就可以变换成公式(2)：Now the time in equation (1) is converted to the sub-frame number, where the unit of the timer timing value is generally ms, then the formula (1) can be transformed into the formula (2):
超时的时间(ms)＝(当前子帧号％10240×1(ms)+定时器定时值(ms))Timeout time (ms) = (current subframe number % 10240 × 1 (ms) + timer timing value (ms))
(2)；(2);
由于子帧号到10240会反转为0，所以公式(2)中需要对10240做求余数(％)运算；下面将超时的时间以及定时器定时值都可以采用子帧序号来表示，即公式(2)可变换成公式(3)：Since the sub-frame number will be inverted to 0 by 10240, the remainder (%) operation of 10240 is needed in formula (2); the timeout time and the timer timing value can be expressed by the sub-frame number, that is, the formula (2) can be transformed into formula (3):
超时的时间标签＝(当前子帧号+定时数值)％10240    (3)；Timeout tag = (current subframe number + timing value) %10240 (3);
其中所述定时数值为定时器定时值所对应的数值，即定时数值等于定时器定时值除以1毫秒，而超时的时间标签等于超时的时间除以1毫秒；。The timing value is a value corresponding to the timer timing value, that is, the timing value is equal to the timer timing value divided by 1 millisecond, and the timeout time stamp is equal to the timeout period divided by 1 millisecond;
PDCP将SDU处理完生成PDU，投递给RLC层，RLC层按照逻辑信道存储在自己的队列中。当每次子帧中断发生时，在子帧中断的处理程序 中检查RLC每个逻辑信道缓存队列中的数据单元(PDCP PDU)关联的时间标签；如果当前的子帧号没有达到或没有超过该时间标签，则认为该PDCP PDU没有超时，不需要丢弃；由于队列的顺序性，该数据之后的数据就没必要再检测是否超时了。如果当前的子帧号达到或超过该时间标签，则认为超时并需要丢弃该数据，然后再检测下一个数据。The PDCP processes the SDU to generate a PDU, which is delivered to the RLC layer, and the RLC layer is stored in its own queue according to the logical channel. The handler for the interrupt in the sub-frame when each sub-frame interrupt occurs Checking the time label associated with the data unit (PDCP PDU) in each logical channel buffer queue of the RLC; if the current subframe number does not reach or exceed the time label, the PDCP PDU is considered to have no timeout and does not need to be discarded; The order of the queue, the data after the data is no longer necessary to detect whether it has timed out. If the current subframe number meets or exceeds the time stamp, the timeout is considered and the data needs to be discarded, and then the next data is detected.
超时也需要考虑子帧号反转的情况，由于协议规定discardtimer最大的定时值是1500ms，所以如果发生时间标签反转而当前子帧号还没有反转的情况，当前子帧号会比时间标签大很多，远远大于1500。所以判断没有超时的公式(4)如下：The timeout also needs to consider the case where the subframe number is reversed. Since the protocol specifies that the maximum timing value of the discard timer is 1500 ms, if the time label inversion occurs and the current subframe number has not been inverted, the current subframe number will be compared to the time label. A lot bigger, far greater than 1500. So the formula (4) that judges that there is no timeout is as follows:
(时间标签>当前子帧号)or((时间标签<当前子帧号)and((当前子帧号-时间标签)>1500))    (4)；(time tag > current subframe number) or ((time tag <current subframe number) and ((current subframe number - time tag) > 1500)) (4);
公式(4)中的时间标签即为公式(3)中的超时的时间标签，；本发明实施例只是采用子帧中断作为定时机制，再加上关联的超时标签即可代替大量定时器完成的功能，因此，本发明实施例提供的技术方案，能够减轻操作***的负荷，而且具有简洁高效的特点。The time stamp in the formula (4) is the time stamp of the timeout in the formula (3), and the embodiment of the present invention only uses the subframe interrupt as the timing mechanism, and the associated timeout label can be replaced by a large number of timers. The technical solution provided by the embodiment of the invention can reduce the load of the operating system and has the characteristics of simplicity and high efficiency.
