Description

报文处理方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种报文处理方法、装置及系统。
背景技术
LTE的层2用户面协议栈由3个子层组成，分为分组数据汇聚协议(Packet Data Convergence Protocol，简称为PDCP)、无线链路控制(Radio Link Control，简称为RLC)和媒体接入控制(Media Access Control，简称为MAC)。其中PDCP层主要功能包括头压缩、安全性功能(完整性保护和加密)以及对切换时重排序和重传的支持，这些功能取决于无线承载。每一无线承载有一个PDCP实体。
PDCP层发送端处理流程：从上层接收到业务数据单元(Service Data Unit，简称为SDU)后，赋予序列号(Sequence Number，简称为SN)值，如果需要完整性保护，则执行完整性保护处理；如果需要加密，则执行加密处理；维护发送端的序列号和超帧号(Hyper Frame Number，简称为HFN)值，将协议数据单元(Protocol Data Unit，简称为PDU)发送给下层处理。
PDCP层接收端处理流程：从下层接收到协议数据单元PDU，如果需要解密，执行解密处理；如果需要完整性保护，执行完整性保护校验；根据接收到序列号SN维护本地的接收序列号SN和超帧号HFN值，将业务数据单元SDU投递到高层处理。
随着LTE的大规模商用和移动互联网的蓬勃发展，网络中的业务类型变得更加的丰富，各种各样的报文都存在，比如很多的O2O应用、如微信、易信，微博等，还有传输控制协议(Transmission Control Protocol，简称为TCP)的ACK反馈报文等，这些报文的特点都是小包，而且是非常频繁，数据量比较大。
但目前不论是终端侧或者是网络侧，PDCP协议的处理基本上都是类中央处理单元(Central Processing Unit，简称为CPU)的芯片，其主要特点是线性处理，小包处理能力较差。而根据PDCP协议，高层的每一个SDU都需要独立处理，经过PDCP协议处理后形成PDU发送给低层协议栈，如RLC。这样就会导致终端或者网络侧PDCP层处理小报文能力非常差，而空口带宽又无法得到足够的利用。例如，频分双工(Frequency Division Duplex，简称为FDD)20M带宽小区，空口能力是150Mbps，假设芯片每秒能处理10000个报文，如果每个报文大小是1500字节，则流量是110Mbps 左右；如果每个报文大小是64字节，则流量仅仅有5Mbps左右。当然，考虑到1500字节和64字节内存处理等因素，可能会更高一些，但是流量还是非常的低，远远没法满足真实商用环境的需求。
对于这种小包的问题，目前的处理方法一般是使用更高速的处理器，更大的内存，但是基本上是治标不治本。
针对相关技术中不能解决小报文处理能力较差的问题，目前尚未提出有效的解决方案。

根据本发明的另一方面，还提供了一种报文处理系统，包括：至少包括上述装置的发送设备，和接收设备，其中，该接收设备设置为在接收到对该至少两个报文进行组包后的数据包后，对该数据包进行解析处理。
下面结合优选实施方式对本发明实施例进行进一步说明。
本发明实施例的关键是在PDCP协议层和高层之间增加一个小包缓存区，图6是根据本发明优选实施例的报文处理装置的示意图，如图6所示，该缓存区主要用于：如果缓存区中的报文字节数大于等于N字节，或者缓存区第一个报文等待的时间超过T时间；把缓存区中的所有报文一起发送到PDCP协议层作为一个SUD进行发送；否则，在缓存区进行等待。在增加缓存区后，将小包打包成一个SDU在PDCP层进行处理，因此会对现在的PDCP协议报文格式有一定的改动，需要对于标准PDCP协议报文进行一定的扩展，使用了PDCP中的保留字段来表明是否启用。
为了在终端侧以及网络侧PDCP层同时配置或者不配置小包处理功能，需要在RRC协议36.331中针对PDCP层的配置添加可选字段，在PDCP-Config报文格式中增加一个标识，以标识是否打开小包处理功能；并且增加小包处理功能需要的两个配置参数：延时定时器(DelayTimer)，小包缓存区在有第一个缓存的小包时启动的定时 器，如果定时器超时，则把缓存区中的所有报文都投递给PDCP层；最大累计字节(MaxCulBytes)，小包缓存区最大缓存的报文字节数，如果超过此值，则把缓存区中的所有报文都投递给PDCP层。
下面对增加了小包处理功能的PDCP配置进行说明。
Figure PCTCN2015074329-appb-000001
Figure PCTCN2015074329-appb-000002
其中，上述斜体部分所描述的内容即是在36.331协议PDCP-Config参数配置中增加小包处理的协议字段，字段含义解释如下：
PDCP-smallpacket    指示PDCP小包功能是否使能；
DelayTimer          延时定时器时长；
MaxCulBytes         最大组包长度。
如果PDCP层没有配置小包处理功能，则按照标准PDCP协议处理；如果PDCP层配置了小包处理功能，则按照小包处理功能进行处理；在RRC协议中，配置PDCP实例时，增加小包处理的选项；在选项使能的情况下，配置延时定时器和最大组包长度，也即MaxCulBytes。
图7是根据本发明优选实施例的小包处理功能配置的流程图，如图7所示，该方法包括以下步骤：
步骤S702，RRC配置PDCP配置消息；
步骤S704，PDCP层解析配置消息；
步骤S706，判断是否使能小包处理功能，在判断结果为是的情况下，执行步骤S708，否则执行步骤S712；
步骤S708，创建小包缓存区；
步骤S710，存储延时定时器和最大组包长度
步骤S712，配置结束。
结合图7所示的流程，小包功能使能配置处理流程包括以下内容：PDCP层小包功能使能开关打开；RRC配置PDCP-config消息中携带了小包(SmallPacket)的参数，即延时定时器DelayTimer和最大组包长度MaxCulBytes；PDCP协议层配置PDCP实例时，创建一个小包缓存区，并且保存延时定时器DelayTimer和最大组包长度MaxCulBytes；对于发送端，高层报文到达时先送到PDCP小包缓存区，根据配置的延时定时器DelayTimer和最大组包长度MaxCulBytes来判断报文如何处理；对于接收端，在PDCP小包功能使能的情况下，需要将小包解开后，分别发送到高层，后续报文处理按照小包流程处理。
小包功能非使能配置处理流程包括以下内容：PDCP层小包功能使能开关关闭；RRC配置PDCP-config消息中不携带SmallPacket的相关参数；PDCP协议层配置PDCP实例；按照正常PDCP流程进行处理。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处 的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
