Description

数据处理的方法及其装置 技术领域
本申请涉及通信领域，并且，更具体地，涉及一种数据处理的方法及其装置。
背景技术
在无线通信的过程中，终端设备经常会发生基站切换或重新建立与基站的连接的过程。在上述过程中，网络配置可能存在一些变化，例如，在不同(高低)版本的协议之间，不同接入制式间的切换，切换的目标基站会根据上述变化，判定需要使用FullConfig流程，使得分组数据汇聚协议(packet data convergence protocol,PDCP)层的实体配置可以和目标基站保持一致，完成用户面数据传输。
然而，FullConfig流程会导致PDCP层丢包，影响用户的体验。所以，如何提升无线通信系统的移动性流程中的性能，成为了待以解决的问题。
发明内容
本申请提供一种数据处理的方法及其装置，即使RRC重配置信令中包含FullConfig信元，也不需要丢弃PDCP实体(包括PDCP实体携带的数据)，避免PDCP层丢包的现象，改善无线资源重配置流程的性能，提升用户的体验。
第一方面，提供了一种数据处理的方法，包括：无线通信装置接收来自基站的无线资源控制(radio resource control，RRC)消息，该RRC消息中包括第一配置字段，该第一配置字段用于指示释放第一分组数据汇聚层协议(packet data convergence protocol，PDCP)实体；该无线通信装置挂起该第一PDCP实体，该第一PDCP实体携带第一数据；该无线通信装置向该基站发送该第一数据。
具体地，该RRC消息可以是空口重配置消息，其中，第一配置字段用于指示释放第一PDCP实体，例如，该第一配置字段使得信元FullConfig设置为真(true)，指示无线通信装置需要按照FullConfig流程处理。其中，FullConfig流程包括释放PDCP实体(第一PDCP实体)的操作，无线通信装置的PDCP层会丢弃保存的PDCP SDU与PDCP PDU，从而，丢弃第一PDCP实体携带的第一数据。
其中，PDCP实体位于PDCP层，对于一个终端设备而言，可以定义多个PDCP实体，每个PDCP实体携带一个无线承载的数据。
以及，无线通信设备在接收RRC消息之后，并没有按照FullConfig流程，释放第一PDCP实体，丢弃保存的PDCP SDU(包括第一数据)与PDCP PDU，而是对第一PDCP实体进行挂起操作，将第一PDCP实体由激活(active)态置为挂起(suspend)态，从而第一PDCP实体为暂停传输数据的状态，并未丢弃保存的PDCP SDU(包括第一数据)与PDCP PDU。
举例而言，无线通信设备的RRC层接收基站发送的指示需要按照FullConfig流程处 理的RRC消息之后，可以将需要挂起的PDCP实体(第一PDCP实体)列表发送至PDCP层，并指示PDCP层挂起该PDCP实体(第一PDCP实体)。
基于上述方案，无线通信装置接收RRC消息，并未根据RRC消息释放第一PDCP实体，丢弃第一PDCP实体携带的数据，而是挂起该第一PDCP实体，保留了第一PDCP实体携带的第一数据，从而可以向基站发送第一数据。避免了因RRC消息的信元FullConfig设置为真，在无线通信装置进行FullConfig流程的过程中，因执行FullConfig流程需要释放PDCP实体(包括第一PDCP实体)，丢弃PDCP实体承载的数据(包括第一数据)，从而导致的丢包现象，提高数据传输的完整性，改善系统的传输性能，提升用户体验。
在一种可能的实现方式中，该无线通信装置根据该RRC消息，向该基站发起随机接入。
在一种可能的实现方式中，该无线通信装置根据该RRC消息，建立PDCP实体集合，该PDCP实体集合包括至少一个PDCP实体。
基于上述方案，通过建立PDCP实体集合，可以在后续的步骤中，为无线通信装置向基站发送第一数据做准备。
在一种可能的实现方式中，该RRC消息包括该第一PDCP实体的演进分组系统承载标识的信息，其中，在该随机接入成功的情况下，该无线通信装置根据该第一PDCP实体的演进分组系统承载标识(eps-beareridentiy)，确定第二PDCP实体，该第二PDCP实体属于该PDCP实体集合，该第二PDCP实体与该第一PDCP实体具有相同的演进分组系统承载标识；该无线通信装置将该第一数据转移至该第二PDCP实体；该无线通信装置通过该第二PDCP实体向该基站发送该第一数据。
在一种可能的实现方式中，该无线通信装置释放该第一PDCP实体。
示例地，在无线通信设备向基站发起目标小区的随机接入成功的情况下，无线通信设备可以向基站发送重配置完成消息，表征已成功完成FullConfig流程。之后，无线通信设备可以根据RRC消息中携带的第一PDCP实体的演进分组系统承载标识，遍历PDCP实体集合，确定第二PDCP实体。该第二PDCP实体属于PDCP实体集合(是PDCP实体集合中的一个PDCP实体)，且第二PDCP实体与第一PDCP实体具有相同的演进分组系统承载标识。继而，将挂起状态的第一PDCP实体携带的第一数据转移至第二PDCP实体，通过第二PDCP实体向基站发送第一数据。最后，由于第一数据已从第一PDCP实体转移至第二PDCP实体，并发送至基站，无线通信设备可以释放挂起的PDCP实体(第一PDCP实体)。
基于上述方案，在无线通信设备向基站发起目标小区的随机接入成功的情况下，无线通信设备根据RRC消息携带的第一PDCP实体的演进分组系统承载标识，在PDCP实体集合中确定具有相同演进分组系统承载标识的第二PDCP实体，并将已挂起的第一PDCP实体携带的第一数据转移至第二PDCP实体，通过第二PDCP实体向基站发送第一数据。最后，释放挂起的第一PDCP实体。从而，可以确保在接收RRC消息之后，第一PDCP实体携带的第一数据不被丢弃，使用第二PDCP实体发送第一数据，提升用户的体验。最后释放第一PDCP实体，使得该PDCP实体可以因无数据传输被释放，如若因其他业务在需要PDCP实体的情况下可以新建相应的PDCP实体，避免资源的浪费。
在一种可能的实现方式中，在该随机接入失败的情况下，该无线通信装置恢复该第一PDCP实体；该无线通信装置通过该第一PDCP实体向该基站发送该第一数据。
在一种可能的实现方式中，该无线通信装置释放该PDCP实体集合。
示例地，在无线通信设备向基站发起目标小区的随机接入失败的情况下，无线通信装置恢复挂起的PDCP实体(第一PDCP实体)，即，将PDCP实体(第一PDCP实体)的状态由挂起(suspend)态置为激活(active)态，使得第一PDCP实体可以正常传输数据。由于无线通信装置恢复了挂起的PDCP实体(第一PDCP实体)，从而也恢复了第一数据，可以通过恢复的第一PDCP实体向基站发送第一数据。
进一步地，由于无线通信装置可以通过第一PDCP实体向基站发送第一数据，所以可以释放PDCP实体集合。
基于上述方案，在无线通信设备向基站发起目标小区的随机接入失败的情况下，无线通信设备通过恢复挂起的第一PDCP实体，使得第一PDCP实体可以正常传输第一数据，从而通过第一PDCP实体向基站发送第一数据。从而，能够保留第一PDCP实体携带的第一数据，并继续向基站发送第一数据，避免数据包丢失的现象，使得业务的数据不会被丢失，提升了用户的体验。最后释放PDCP实体集合，避免资源的浪费。

基于上述方案，有益效果可以参考第一方案的相关描述，为了简洁，本申请在此不做赘述。

图3是适用于本申请实施例的用户面协议栈系统300的一示意图。如图3所示，用户设备(user equipment,UE)主要包括非接入(non-access stratum,NAS)层、无线资源控制(radio resource control,RRC)层、分组数据汇聚层协议(packet data convergence protocol,PDCP)层、无线链路控制(radio link control,RLC)层、介质访问控制层(media access control,MAC)与端口物理层(physical layer,PHY)；eNB主要包括RRC层、PDCP层、RLC层、MAC层与PHY层；移动管理实体(mobile managenment entity,MME)主要包括NAS层。通过端到端对等通信，完成无线空口数据传输的过程。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
1.服务数据单元和协议数据单元
服务数据单元(Service data unit,SDU)和上一层的协议数据单元(Protocol data unit，PDU)是一一对应的。进入每个子层未被处理的数据称为服务数据单元(SDU)，经过子层处理后形成特定格式的数据被称为协议数据单元(PDU)。同时，本层形成的PDU即为下一层的SDU。根据协议数据单元的数据的不同，送到接收端的指定层。
2.无线资源控制层
无线资源控制(radio resource control,RRC)层控制着UE和eNB在无线空中接口的通信和UE跨小区的移动性。LTE是接入网，所以RRC是接入层AS控制平面中的最高层。
RRC层主要包含广播核心网非接入层提供的信息。负责网络系统信息向UE的广播。系统信息通常情况下按照一定的基本规律重复，RRC负责执行计划、分割和重复、建立、重新建立、维持和释放在UE和接入网之间的RRC连接。
3.分组数据汇聚协议层
分组数据汇聚协议(packet data convergence protocol,PDCP)层，负责执行IP头压缩，以减少无线接口必须传送的比特流量。属于无线接口协议栈的第二层，处理控制平面上的无线资源控制(RRC)消息。PDCP子层为上层RRC提供信令传输服务，并实现RRC信令的加密和一致性保护，以及在反方向上实现RRC信令的解密和一致性检查。
4.FullConfig流程
无线通信系统中的网络侧可以通过使用FullConfig流程，处理移动过程中针对协议的版本(高低)不同，或者其它一些网络认为无法避免的场景。简言之，FullConfig流程就是保持NAS层的承载，对于空口承载，则释放原有的承载，新建新的承载。
图4是FullConfig流程的一示意图。如图4所示，FullConfig流程处理的承载是空口承载，保持NAS层用户面承载E-RAB对应的演进分组系统承载标识(envolved packet system beareridentity,eps-BearerIdentity)，待空口承载释放和新建流程处理完成，则可以恢复eps-BearerIdentity的数据传输。
在上行发送的过程中，换言之，就是UE发送缓冲区状态报告(buffer state report,BSR)给基站，基站根据调度算法向UE下发资源授权，UE通过基站配置的上行资源发送数据，完成发送的过程。对于应用层数据，在到达PDCP层之后，PDCP层可以对应用数据进行缓存，该缓存即为PDCP层的BSR值。由于空口授权受限因素较多，存在不确定性，因而PDCP层的上行缓存机制对于数据包的发送起到了很大的作用。
然而，综上所述，在FullConfig场景下，由于需要释放PDCP实体，在释放之时，需 要同时丢弃缓存的PDCP SDU和PDCP PDU。而在移动通信的过程中，FullConfig场景是一个普遍发生的流程，因此，由于数据的丢弃，存在影响应用层业务连续性的问题，从而影响用户的体验。
鉴于此，本申请提供一种数据处理的方法，可以针对FullConfig场景下的释放流程，不立即执行释放动作，而是先对旧的PDCP实体进行备份，包括PDCP实体的配置以及数据缓存，然后，RRC层把新的PDCP实体的配置信息发送给PDCP层，PDCP层建立新的实体。如图4所示，空口承载的变化，不会影响非接入层承载E-RAB，即eps-BearerIdentity。因而，可以通过eps-BearerIdentity找到FullConfig流程后对应的数据无线承载(data radio bearer,DRB)，从而将已备份的旧的PDCP实体的缓存数据转发给新建的PDCP实体，使用新建的PDCP实体完成缓存数据的发送。
图5为本申请实施例提供的数据处理的方法500的一示意图。如图5所示，该方法500可以包括以下步骤：
S501，基站向无线通信装置发送RRC消息。对应地，无线通信装置接收来自基站的RRC消息。
示例地，基站可以向无线通信装置发送RRC消息，该RRC消息包括第一配置字段，第一配置字段用于指示释放第一PDCP实体，第一PDCP实体携带第一数据。
具体地，基站向无线通信装置发送RRC消息，该RRC消息可以是空口重配置消息，其中，第一配置字段用于指示释放第一PDCP实体，例如，该第一配置字段使得信元FullConfig设置为真(true)，指示无线通信装置需要按照FullConfig流程处理。其中，FullConfig流程包括释放PDCP实体(第一PDCP实体)的操作，无线通信装置的PDCP层会丢弃保存的PDCP SDU与PDCP PDU，从而，丢弃第一PDCP实体携带的第一数据。
其中，PDCP实体(PDCP entity)是通过基站向无线通信装置配置的，无线通信装置基于基站发送的PDCP层的配置信息，生成相应的PDCP实体。PDCP实体是通过软件的方式实现的，位于PDCP层，与控制面或用户面相关联。对于一个终端设备而言，可以定义多个PDCP实体，每个PDCP实体承载一个无线承载的数据。
S502，无线通信设备挂起第一PDCP实体。
示例地，无线通信设备在接收RRC消息之后，可以挂起第一PDCP实体，即，将第一PDCP实体设置为暂停(suspend)的状态。
具体地，无线通信设备在接收RRC消息之后，并没有按照FullConfig流程，释放第一PDCP实体，丢弃保存的PDCP SDU与PDCP PDU，该PDCPSDU中包括第一数据，而是对第一PDCP实体进行挂起操作，使得第一PDCP实体由激活(active)态置为挂起(suspend)态，从而第一PDCP实体为暂停传输数据的状态。
举例而言，无线通信设备的RRC层接收基站发送的指示需要按照FullConfig流程处理的RRC消息之后，可以将需要挂起的PDCP实体(第一PDCP实体)列表发送至PDCP层，并指示PDCP层挂起该PDCP实体(第一PDCP实体)。
S503，无线通信装置向基站发送第一数据。对应地，基站接收来自无线通信装置的第一数据。
示例地，无线通信设备在接收RRC消息后，并未丢弃第一PDCP实体携带的第一数据，而是将第一数据发送给基站。
具体地，首先，无线通信设备可以根据RRC消息，建立PDCP实体集合，该PDCP 实体集合包括至少一个PDCP实体。之后，无线通信设备可以根据RRC消息，向基站发起目的小区的随机接入。其中，因为RRC消息为空口重配置消息，所以无线通信设备可以根据该RRC消息中包括的随机接入信道的配置信息与随机接入的参数信息，向基站发起目的小区的随机接入。
在可能实现的一种方式中，在无线通信设备向基站发起目标小区的随机接入成功的情况下，无线通信设备可以向基站发送重配置完成消息，表征已成功完成FullConfig流程。之后，无线通信设备可以根据RRC消息中携带的第一PDCP实体的演进分组系统承载标识(eps-beareridentiy)，遍历PDCP实体集合，确定第二PDCP实体。该第二PDCP实体属于PDCP实体集合(是PDCP实体集合中的一个PDCP实体)，且第二PDCP实体与第一PDCP实体具有相同的演进分组系统承载标识。继而，将挂起状态的第一PDCP实体携带的第一数据转移至第二PDCP实体，通过第二PDCP实体向基站发送第一数据。最后，由于第一数据已从第一PDCP实体转移至第二PDCP实体，并发送至基站，无线通信设备可以释放挂起的PDCP实体(第一PDCP实体)。
在可能实现的另一种方式中，在无线通信设备向基站发起目标小区的随机接入失败的情况下，无线通信装置恢复挂起的PDCP实体(第一PDCP实体)，即，将PDCP实体(第一PDCP实体)的状态由挂起(suspend)态置为激活(active)态，使得第一PDCP实体可以正常传输数据。由于无线通信装置恢复了挂起的PDCP实体(第一PDCP实体)，从而也恢复了第一数据，可以通过恢复的第一PDCP实体向基站发送第一数据。
进一步地，由于无线通信装置可以通过第一PDCP实体向基站发送第一数据，所以可以释放PDCP实体集合。
应理解，在本实施例中，PDCPSDU可以承载普通的分组服务(packet service,PS)业务数据包，也可以承载IP多媒体子系统(IP multimedia subsystem,IMS)信令数据包，本申请在此不做限定。
基于上述方案，无线通信装置接收RRC消息，并未根据RRC消息释放第一PDCP实体，丢弃第一PDCP实体携带的数据，而是挂起该第一PDCP实体，保留了第一PDCP实体携带的第一数据，从而可以向基站发送第一数据，避免了因RRC消息的信元FullConfig设置为真，在无线通信装置进行FullConfig流程的过程中，因执行FullConfig流程需要释放PDCP实体(包括第一PDCP实体)，丢弃PDCP实体承载的数据(包括第一数据)，从而导致的丢包现象，提高数据传输的完整性，改善系统的传输性能，提升用户体验。例如，在PDCPSDU承载普通的PS业务数据包的情况下，可以避免传输控制协议(transmission control protocol,TCP)建链握手失败；在PDCPSDU承载IMS信令数据包的情况下，可以避免出现掉话的现象。
一方面，在无线通信设备向基站发起目标小区的随机接入成功的情况下，无线通信设备根据RRC消息携带的第一PDCP实体的演进分组系统承载标识，在PDCP实体集合中确定具有相同演进分组系统承载标识的第二PDCP实体，并将已挂起的第一PDCP实体携带的第一数据转移至第二PDCP实体，通过第二PDCP实体向基站发送第一数据。最后，释放挂起的第一PDCP实体。从而，可以确保在接收RRC消息之后，第一PDCP实体携带的第一数据不被丢弃，使用第二PDCP实体发送第一数据，提升用户的体验。最后释放第一PDCP实体，使得该第一PDCP实体可以因无数据传输被释放，如若因其他业务在需要PDCP实体的情况下可以新建相应的PDCP实体，避免资源的浪费；另一方面，在无线 通信设备向基站发起目标小区的随机接入失败的情况下，无线通信设备通过恢复挂起的第一PDCP实体，使得第一PDCP实体可以正常传输第一数据，从而通过第一PDCP实体向基站发送第一数据。从而，能够保留第一PDCP实体携带的第一数据，并继续向基站发送第一数据，避免数据包丢失的现象，使得业务的数据不会被丢失，提升了用户的体验。最后释放PDCP实体集合，避免资源的浪费。

S607，无线通信装置的PDCP层将第一数据转移至第二PDCP实体。
示例地，无线通信装置的PDCP层在确定第二PDCP实体之后，可以将第一PDCP实体携带的第一数据转移至第二PDCP实体，使得无线通信装置可以通过第二PDCP实体向基站发送第一数据。
S608，无线通信装置的RRC层向无线通信装置的PDCP层发送释放第一PDCP实体的信息。对应地，无线通信装置的PDCP层接收来自无线通信装置的RRC层的释放第一PDCP实体的信息。
示例地，由于第一数据已从第一PDCP实体转移至第二PDCP实体，并发送至基站，无线通信设备的RRC层可以向无线通信装置的PDCP层发送释放挂起的第一PDCP实体的信息，使得无线通信装置的PDCP层释放第一PDCP实体，及其携带的数据。
应理解，在本实施例中，PDCPSDU可以承载普通的PS业务数据包，也可以承载IMS信令数据包，本申请在此不做限定。
基于上述方案，无线通信装置的RRC层接收RRC消息，无线通信装置的PDCP层并未根据RRC消息释放第一PDCP实体，丢弃第一PDCP实体携带的数据，而是挂起该第一PDCP实体，保留了第一PDCP实体携带的第一数据，从而可以向基站发送第一数据，避免了因RRC消息的信元FullConfig设置为真，在无线通信装置进行FullConfig流程的过程中，因执行FullConfig流程需要释放PDCP实体(包括第一PDCP实体)，丢弃PDCP实体承载的数据(包括第一数据)，从而导致的丢包现象，提高数据传输的完整性，改善系统的传输性能，提升用户体验。
其中，在无线通信设备向基站发起目标小区的随机接入成功的情况下，无线通信设备的PDCP层根据RRC消息携带的第一PDCP实体的演进分组系统承载标识，在新建的PDCP实体集合中确定具有相同演进分组系统承载标识的第二PDCP实体，并将已挂起的第一PDCP实体携带的第一数据转移至第二PDCP实体，通过第二PDCP实体向基站发送第一数据。最后，无线通信设备的PDCP层释放挂起的第一PDCP实体。从而，可以确保在接收RRC消息之后，第一PDCP实体携带的第一数据不被丢弃，使用第二PDCP实体 发送第一数据，提升用户的体验。最后释放第一PDCP实体，使得该PDCP实体可以因无数据传输被释放，如若因其他业务在需要PDCP实体的情况下可以新建相应的PDCP实体，避免资源的浪费。
