相关申请的交叉引用
本申请基于申请号为201610801045.8、申请日为2016年09月01日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明涉及无线通信技术领域，尤其涉及一种高速下行分组接入(High Speed Downlink Packet Access，HSDPA)存储管理的方法和装置、设备、存储介质。
背景技术
HSDPA是第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)版本5(Release5)提出的一种增强方案，其同时适用于宽带码分多址(Wideband Code Division Multiple Access，WCDMA)和时分双工(Time Division Duplex，TD)系统。HSDPA的主要目标是支持高速分组数据业务，同时保证更低的时间延迟、更高的系统吞吐量和更强的服务质量(Quality of Service，QoS)保证。
在TD和WCDMA系统中，HSDPA业务具有实时性强和数据量大的特点；其中，TD系统每隔传输时间间隔(Transmission Timing Interval，TTI)接收到一包HSDPA数据，这里的TTI可以是5毫秒(ms)等；而在WCDMA系统中，则是系统每隔TTI(2ms)接收到一包HSDPA数据，这里的TTI可以是2ms等。如果下行链路质量过差，实时堆积的数据量会比较大。
目前，对HSDPA如何做存储管理现有的通信协议无明确描述，如果完 全按照理论最大值来给HSDPA业务划分存储资源，无疑是对存储资源是一种极大的浪费。因此需要依据实际HSDPA业务数据量，研究一种满足HSDPA业务需求的HSDPA存储管理方法，来解决存储资源浪费的现状。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
图1为本发明实施例HSDPA数据流向图，如图1所示，HSDPA数据流向如下：
首先，获得混合自动重传请求(Hybrid Automatic Repeat request，HARQ)数据。物理层解析高速下行链路共享信道(High-Speed Downlink Shared Channel，HS-DSCH)成功后，则为HARQ数据申请存储块，媒体介入控制层(Media Access Control，MAC层)解析完HARQ数据，则释放HARQ存储块。
其次，将HARQ数据中的队列数据依次存入到MAC层对应的Que(0)到Que(n)。Que(0)到Que(n)分别缓存队列0到队列n的重排数据。
最后，将MAC层中Que(0)到Que(n)的缓存的队列数据分别传递到RLC层对应的RB(Idx0)到RB(Idxn)中。RB(Idx0)到RB(Idxn)分别表示索引为0的RB到索引为n的RB，这些RB的窗口缓存无线链路控制层协议数据单元(Radio Link Control Protocol Data Unit，RLC PDU)信息。
图2为本发明实施例HSDPA存储管理图，如图2所示，HSDPA存储管理可以包括：HARQ存储区管理和Type存储区管理，对于这两类数据的管理可以使用空闲链表的方式来管理，当有数据需要申请存储块时，可以直接从空闲链表的头获取一个存储块；释放数据后则将存储块保存于空闲链表尾部。
本发明的以下实施例可以基于上述记载的HSDPA数据流向和HSDPA存储管理而提出，图3为本发明实施例HSDPA存储管理的方法的流程图，如图3所示，该方法包括：
步骤100：连续多次获取HARQ数据，并依据预设的存储管理策略存储每次获取的HARQ数据。
所述存储管理策略为：为需要存储的数据申请一个存储块，所述数据的存储块，配置为在释放数据后被回收，所述被回收的存储块被循环利用。
也就是说，为需要存储的数据申请一个存储块，所述数据的存储块，配置为在释放数据后存储下一个需要存储的数据。
在每次获取HARQ数据后，所述方法还包括：为每次获取的HARQ数据申请一个存储块并存储，每次获取的HARQ数据申请的存储块的个数依据UE实际的数据处理能力确定，每次获取的HARQ数据申请的存储块的大小等于HSPDA最大传输块的大小。所述HSPDA最大传输块的大小由实际信道质量或获取HARQ数据的UE所支持的下行分组业务决定。
可以理解的是，UE每接收一个基站发送的HARQ数据，并在物理层解析完HARQ数据成功后，则申请一块存储块，并投递给MAC层，MAC层解析完该存储块，则释放之。
由图2可以看出，HARQ存储区域中HARQ0存储块到HARQm存储块用来存储连续获取的HARQ数据，物理层解析完HARQ数据成功后，在HARQ0存储块到HARQm存储块中申请一块HARQi存储块，并将该HARQi存储块投递给MAC层处理，i取值范围为0到m，HARQ存储区域中存储块的个数可以取2。
步骤101：确定每次获取的HARQ数据的每个队列数据的存储区域，依据所述存储管理策略将所述每个队列数据存储在相应的存储区域，所述每个队列数据的存储区域由对应的队列数据的大小确定。
在本发明的实施例中，本步骤可以包括：
第一步，预先划分出n个不同等级的存储区域，n大于1；其中，每个等级的存储区域包括至少一个存储块；在任意一个等级的存储区域的存储块的个数大于1时，对应等级的存储区域的各个存储块的大小相同；任意两个不同等级的存储区域的存储块的大小不同。
由图2的HSDPA存储管理图中的Type存储区管理可以看出，Type0到Typen表示预先划分的不同等级的存储区域，每个等级的存储区域与一个等级RLC PDU对应，这里，RLCsize表示对应等级的RLC PDU的大小，每个等级RLC PDU的大小均不同。
以WCDMA为例，实际网络中，用到的RLCsize包括144bits、336bits、4800bits等等，可以将存储区域划分成三个等级Type0、Type1、Type2，不同等级的存储区域Type0、Type1、Type2分别对应RLCsize是144bits、336bits、4800bits。不同存储区域的网络配置不同，RLC PDU的等级可以做适当的调整。
这里，Type0存储区域中包括Type0存储块0到Type0存储块i，Type1存储区域中包括Type1存储块0到Type1存储块j，以此类推，Typen存储区域中包括Typen存储块0到Typen存储块k。
这里，每个等级的存储区域与一个等级的RLC PDU对应；依据每个等级的RLC PDU的大小，确定对应等级的存储区域的存储块个数。
如图4所示，确定Type存储区域存储块个数的方法可以包括以下步骤：
步骤1011a：存储块个数最大范围评估。
示例性地，当一个HARQ数据包含一包RLC PDU数据，另外最大HSDPA队列窗口为128，一个HSDPA队列窗口可以最多包含128个RLC PDU，最少包含1个RLC PDU。RB最大窗口个数为4096，一个最大的HSDPA队列窗口数据不足以填满RB整个窗口，当一个HSDPA队列窗口 只包含1个RLC PDU时，一个RB窗口最多包含4096个HSDPA队列窗口。由于一个HSDPA队列窗口需要一个存储块，所以一个RB窗口最多包含4096个存储块，因此每个存储区域中存储块个数不大于4096。
步骤1011b：评估单个Type存储区域存储块个数。
示例性地，Type0存储区域的对应的RLCsize为144bits，具有该RLCsize的RLC PDU一般用于传输信令，且速率不高，而且RB窗口一般配置在128之内，因此，可以将Type0存储区域的存储块的个数设置为128；Type1存储区域对应等级的RLCsize为336bits，RB窗口一般配置在2048，因此，可以将Type1存储区域的存储块的个数设置为2048；Type2存储区域对应的RLCsize为4800bits，RB窗口一般配置在2048，因此，可以将Type2存储区域的存储块的个数设置为2048。由于实际网络差异，不同等级的存储块个数可以依据实际网络做动态调整。
所述方法还包括：确定每个等级的存储区域中存储块的大小，如图5所示，确定Type存储区域存储块大小的方法可以包括以下步骤：
步骤1012a：获取一个存储区域对应等级的RLCsize。
这里，RLCsize表示对应等级的RLC PDU的大小。
步骤1012b：获取一个HARQ数据中一个队列数据所能承载的对应等级的RLC PDU的最大个数Nmax。
这里，Nmax表示一个队列数据所能承载的对应等级的RLC PDU的最大个数。在实际应用中，当UE支持增强型高速下行分组接入HSDPA+时，Nmax取值44；当UE只支持HSDPA时，Nmax取值70。
步骤1012c：判断(Nmax*RLCsize+SMAC 头)是否小于Tbsize(max)的大小，如果是，执行步骤1012d；如果否，执行步骤1012e。
在其他的实施例中，SMAC 头为一个队列数据中MAC头指针的大小，Tbsize(max)是根据UE所支持的下行分组业务中预设列表中最大传输块 的大小。以WCDMA为例，当UE支持HSDPA+时，Tbsize(max)为42192bits；当UE只支持HSDPA时，Tbsize(max)为27952bits。
步骤1012d：存储块大小为(Nmax*RLCsize)。
步骤1012e：存储块大小为Tbsize(max)-SMAC 头。
本发明实施例中，每个等级的存储区域中存储块大小和个数的评估方式，是依据对应等级的RLCsize的配置、HSDPA队列窗口大小、以及RB窗口大小来确定的。每个等级的存储区域中存储块大小和个数的评估方式也可以使用其他方式来评估，例如，依据HSDPA TB size表格(HSDPA协议中传输块大小的表格)来确定，将HSDPA TB size表格均分成多个等级，存储块大小为不同等级的HSDPA TB size，存储块个数可以取三个RB窗口的平均值。
第二步，在划分出的各个存储区域的存储块中，选取出一个大小与对应队列数据的大小相差最小的存储块，将对应队列数据存储在选取出的存储块中。
可以理解的是，在大于队列数据大小的存储块中，选取出一个大小与所述队列数据的大小相差最小的存储块。示例性地，Type0、Type1、Type2的存储区域中存储块的大小分别为1450bits、3370bits、4810bits。HARQ数据中的一个队列数据大小为1500bits，因此，在Type1和Type2存储区域中选取存储块，Type1存储区域中存储块的大小与队列数据最为接近，则确定HARQ数据中队列数据的存储区域为Type1，并在Type1存储区域中为队列数据申请存储块并存储。
本发明实施例提出的存储管理的方法，连续多次获取HARQ数据，并依据预设的存储管理策略存储每次获取的HARQ数据；确定每次获取的HARQ数据的每个队列数据的存储区域，依据所述存储管理策略将所述每个队列数据存储在相应的存储区域，所述每个队列数据的存储区域由对应 的队列数据的大小确定。与现有技术相比，该方法有效的实现了HSDPA业务数据的存储管理，减少存储资源的浪费，提高存储资源的使用效率。
图6为本发明实施例HSDPA存储管理方法的流程图，如图6所示，该流程包括：
步骤200：判断物理层是否接收到HARQ数据。如果否，执行步骤201；如果是，跳到步骤202。
步骤201：存储管理过程结束。
步骤202：为HARQ数据申请存储块，并存储。
在其他实施例中，依据HARQ存储区管理，为该HARQ数据申请存储块，保存HARQ数据到HARQ存储区域中。HARQ存储区域中存储块的个数依据UE的实际数据处理能力来确定；存储块大小需要按照最大HSDPA TB size来规划，以WCDMA为例，存储块大小取42192bits。
步骤203：解析HARQ数据。
可以理解的是，将HARQ数据分成多个队列数据，对每一个队列数据进行解析，并为解析后的队列数据申请存储块。
步骤204：判断HARQ数据中是否存在未解析的队列数据。如果是，跳到步骤206；如果否，执行步骤205。
可以理解的是，一个HARQ数据中包含至少一个队列数据，在将HARQ数据投递给RLC层之前，需要对HARQ数据中每一个队列数据进行解析处理，并通过Type存储区管理为每一个解析后的队列数据重新申请Type存储块，并存储。
步骤205：释放HARQ存储块，返回步骤200。
可以理解的是，将HARQ数据中的所有队列数据均解析完后，便可将存储该HARQ数据的存储块释放，用来存储下一个需要存储的HARQ数据。
本发明实施例中，当HARQ存储区域中存储块的个数取2时，在传输 时间间隔TTI0(2ms)内，物理层解析成功则申请HARQ0存储块，并将该HARQ0存储块投递给MAC层处理，在传输时间间隔TTI1(2ms)内，物理层解析成功则申请HARQ1存储块，并将该HARQ1存储块投递给MAC层处理。在TTI1结束之前，MAC层需要解析完HARQ0存储块，并释放HARQ0存储块，这样传输时间间隔TTI2(2ms)到来时，物理层才可以继续利用HARQ0存储块。
步骤206：为队列数据申请存储块，并存储。
本发明实施例中，为HARQ数据中的一个队列数据申请存储块，先选择Type存储区域，可以依据队列数据的大小选择与Type存储区域中存储块的大小最接近的Type存储区域。再依据Type存储区管理在队列数据对应的Type存储区域中为队列数据申请一个存储块。
示例性地，Type0、Type1、Type2的存储区域中存储块的大小分别为1450bits、3370bits、4810bits。HARQ数据中的一个队列数据的大小为1200bits，将队列数据的大小与Type0、Type1、Type2存储区域中存储块的大小比较后可知，Type0存储区域中存储块的大小与队列数据的大小最为接近，则确定HARQ数据中队列数据的存储区域为Type0存储区域；再通过Type存储区管理在Type0存储区域中为队列数据申请存储块并存储。
步骤207：组RLC PDU，并投递给RLC层。
将队列数据重排后组成RLC PDU，并投递给RLC层。
步骤208：RLC层组无线链路控制层服务数据单元(Radio Link Control Service Data Unit，RLC SDU)完成，释放Type存储区域中的存储块。
当RLC将RLC PDU组装成RLC SDU后，通过Type存储区管理释放存储块。
