具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
以下分别进行详细说明。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包 括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
下面结合附图对本申请的实施例进行描述。
为了实现不同类型承载的变化，目前可用的方案是基于切换流程或者SCG change的流程，重置所有MCG和/或SCG承载。但考虑到这种类型承载变化可能只涉及到个别承载，如果因重置一个承载导致所有承载中断，则会影响所有业务的数据连续性。
请参阅图2，图2是本申请实施例公开的一种网络构架的示意图。图2所示的网络构架包括用户设备110和网络设备120。为了解决上述问题，在一示例中，网络设备120发送重配置指令，所述重配置指令用于指示用户设备110对承载类型进行重配置；用户设备110接收来自网络设备120的重配置指令，然后用户设备110对承载类型进行重配置，最后用户设备110向网络设备120发送结束标志(End-marker，EM)。可见，在本示例中，在重配置承载类型时，无需重置所有MCG和/或SCG承载，只需重配置单个承载类型即可，避免了由于一个承载的变化影响其他承载，进而保证了其他业务的数据连续性。
另外，为了解决上述问题，在另一示例中，网络设备120发送重配置指令，所述重配置指令用于指示用户设备110对承载类型进行重配置；用户设备110接收来自网络设备120的重配置指令，然后用户设备110对承载类型进行重配置，最后用户设备110接收来自网络设备120的EM。可见，在本示例中，在重配置承载类型时，无需重置所有MCG和/或SCG承载，只需重配置单个承载类型即可，避免了由于一个承载的变化影响其他承载，进而保证了其他业务的数据连续性。
其中，用户设备是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的用户设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。
其中，网络设备是指网络侧的节点设备，例如，网络设备可以是蜂窝网络中接入网侧的无线接入网(Radio Access Network，RAN)设备，所谓RAN设备即是一种将用户设备接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(BaseBand Unit，BBU)、管理实体(Mobility Management Entity，MME)；再如，网络设备也可以是无线局域网(Wireless Local Area Network，WLAN)中的节点设备，例如接入控制器(access controller，AC)，网关，或WIFI接入点(Access Point，AP)等。
请参阅图1，图1是本申请实施例公开的一种网络构架的示意图。
下面结合图1所示的网络构架对本申请实施例提供的重配置方法进行详细说明。
请参见图2，图2为本申请实施例提供的一种重配置方法的流程示意图，包括以下步骤：
步骤S201：网络设备发送重配置指令，所述重配置指令用于指示用户设备对承载类型进行重配置。
其中，网络设备发送重配置指令可以是网络设备直接向用户设备发送重配置指令，也可以是网络设备通过其他设备向用户设备发送重配置指令，在此不作限定。
其中，重配置指令可包括以下至少一种：密钥、完整性校验信息参数、承载类型重配置信息，等等。完整性校验是指为保证数据的完整性，用一种指定的算法对数据完整性进行校验的方法。完整性校验信息参数是指校验算法中的变量和设定值。其中，承载类型重配置信息包括需要重配置的承载信息，比如MCG split bearer to SCG split bearer，或者，MCG bearer to SCG split bearer。
步骤S202：用户设备接收来自网络设备的重配置指令；用户设备对承载类型进行重配置。
具体地，用户设备对承载类型进行重配置具体有：用户设备根据所述重配置指令包括的承载类型重配置信息进行重配置。比如，承载类型重配置信息包括MCG split bearer to SCG split bearer，那么用户设备将MCG split bearer切换至SCG split bearer。又比如，承载类型重配置信息包括MCG split bearer to SCG split bearer，那么用户设备将MCG split bearer切换至SCG split bearer。
步骤S203：用户设备向所述网络设备发送EM；网络设备接收来自网络设备的EM。
其中，EM是一个特殊的数据包，EM用于表示发送源侧(本方案中指的是用户设备侧)的数据结束。假如用户设备将MCG split bearer切换至SCG split bearer后，用户设备发送EM表示用户设备在MCG split bearer上发送PDU结束。又假如用户设备将MCG bearer切换至SCG split bearer后，用户设备发送EM表示表示用户设备在MCG bearer上发送PDU结束。
可见，在本方案中，在重配置承载类型时，无需重置所有MCG和/或SCG承载，只需重配置单个承载类型即可，避免了由于一个承载的变化影响其他承载，进而保证了其他业务的数据连续性。
在一示例中，所述用户设备向所述网络设备发送EM之后，所述方法还包括：
所述用户设备进行重置处理，所述重置处理包括重置压缩算法(RObust Header Compression，ROHC)。
其中，重置压缩算法(ROHC)指的是将压缩算法恢复至初始状态。用户设备将压缩算法恢复至初始状态的具体实施方式可参照现有做法，在此不作说明。
在一示例中，所述用户设备进行重置处理之后，所述方法还包括：
网络设备发送状态报告(status report)；
所述用户设备接收来自所述网络设备的所述status report；
所述用户设备根据所述status report向所述网络设备发送协议数据单元(Protocol Data Unit，PDU)。
具体地，所述status report用于表示接收端侧(本方案中指的是网络设备侧)已接收到发送端侧(本方案中指的是用户设备侧)发送的EM。用户设备接收到来自网络设备的status report后，用户设备知道网络设备已经接收到EM后，用户设备才给网络设备发送PDU，可使得用户设备发送的PDU与用户设备的模式同步。比如，用户设备从MCG bearer切换至SCG bearer，那么用户设备接收到status report后，用户设备在向SCG bearer上给网络设备发送PDU。
在一示例中，所述重配置指令包括密钥和/或完整性校验信息参数，所述用户设备向网络设备发送EM之后，所述方法还包括：
所述用户设备根据所述密钥对需要发送的PDU进行加密处理；和/或，所述用户设备根据所述完整性校验信息参数对需要发送的PDU进行完整性校验处理；
所述用户设备向所述网络设备发送处理后的PDU；
网络设备接收来自用户设备发送的PDU；
所述网络设备根据所述密钥对接收到的PDU进行解密处理；和/或，所述网络设备根据所述完整性校验信息参数对接收发送的PDU进行完整性校验处理
具体地，所述用户设备根据所述完整性校验信息参数对需要发送的PDU进行完整性校验处理，具体有：用户设备使用上层提供的密钥计算出完整性校验码，然后将完整性校验码附着在PDCP PDU中，一起进行发送。
在一示例中，所述EM包括计数值(COUNT)，所述COUNT是使用PDCP重配置之前所用密钥进行加密的最后一个数据包的COUNT。
具体地，现有LTE定义的EM格式如图3(1)～图3(3)所示。可见，现有的LTE定义的EM格式中包含有LSN域，且EM格式根据PDU序列号的不同长度而有不同格式。本方案中，为了方便管理使用统一的COUNT，如图4所示，该COUNT长度为32bit长度。
在一示例中，所述status report适用于确认模式(Acknowledged Mode，AM)和(Unacknowledged Mode，UM)。可使得在AM和UM中，发送端(本方案中的用户设备端)都可以确认收端(本方案中的网络设备端)已经正确接收到了EM。
在一示例中，所述EM适用于AM和UM。可见，通过EM使得在一个承载的变化不会影响其他承载。
请参见图5，图5为本申请实施例提供的一种重配置方法的流程示意图，包括以下步骤：
步骤S501：网络设备发送重配置指令，所述重配置指令用于指示用户设备对承载类型进行重配置。
其中，网络设备发送重配置指令可以是网络设备直接向用户设备发送重配置指令，也可以是网络设备通过其他设备向用户设备发送重配置指令，在此不作限定。
其中，重配置指令可包括以下至少一种：密钥、完整性校验信息参数、承载类型重配置信息，等等。完整性校验是指为保证数据的完整性，用一种指定的算法对数据完整性进行校验的方法。完整性校验信息参数是指校验算法中的变量和设定值。其中，承载类型重配置信息包括需要重配置的承载信息，比如MCG split bearer to SCG split bearer，或者，MCG bearer to SCG bearer。
步骤S502：用户设备接收来自网络设备的重配置指令，所述用户设备对承载类型进行重配置。
具体地，用户设备对承载类型进行重配置具体有：用户设备根据所述重配置指令包括的承载类型重配置信息进行重配置。比如，承载类型重配置信息包括MCG split bearer to SCG split bearer，那么用户设备将MCG split bearer切换至SCG split bearer。又比如，承载类型重配置信息包括MCG bearer to SCG bearer，那么用户设备将MCG bearer切换至SCG bearer。
步骤S503：网络设备向用户设备发送EM；用户设备接收来自网络设备的EM。
其中，EM是一个特殊的数据包，EM用于表示发送源侧(本方案中指的是网络设备侧)的数据结束。假如网络设备将MCG split bearer切换至SCG split bearer后，网络设备发送EM表示网络设备在MCG split bearer上发送PDU结束。又假如网络设备将MCG bearer切换至SCG bearer后，网络设备发送EM表示表示网络设备在MCG bearer上发送PDU结束。
可见，在本方案中，在重配置承载类型时，无需重置所有MCG和/或SCG承载，只需重配置单个承载类型即可，避免了由于一个承载的变化影响其他承载，进而保证了其他业务的数据连续性。
在一示例中，所述用户设备接收来自所述网络设备的EM之后，所述方法还包括：
所述用户设备进行重置处理，所述重置处理包括重置压缩算法(ROHC)。
其中，重置压缩算法(ROHC)指的是将压缩算法恢复至初始状态。用户设备将压缩算法恢复至初始状态的具体实施方式可参照现有做法，在此不作说明。
在一示例中，所述用户设备进行重置处理之后，所述方法还包括：
所述用户设备向所述网络设备发送status report，所述status report用于所述网络设备确定向所述用户设备发送的PDU；网络设备接收来自用户设备的所述status report；网络设备根据所述status report发送PDU。
具体地，所述status report用于表示接收端侧(本方案中指的是用户设备侧)已接收到发送端侧(本方案中指的是网络设备侧)发送的EM。网络设备接收到来自用户设备的status report后，网络设备知道用户设备已经接收到EM后，网络设备才给用户设备发送PDU，可使得网络设备发送的PDU与网络设备的模式同步。比如，网络设备从MCG bearer切换至SCG bearer，那么网络设备接收到status report后，网络设备在向SCG bearer上给用户设备发送PDU。
在一示例中，所述重配置指令包括密钥和/或完整性校验参数，所述用户设备接收来自所述网络设备的EM之后，所述方法还包括：
网络设备根据所述密钥对接收到的PDU进行加密处理；和/或，所述网络设备根据所述完整性校验参数对接收到的PDU进行完整性校验处理；
网络设备发送处理后的PDU；
所述用户设备接收网络设备发送的PDU；
所述用户设备根据所述密钥对接收到的PDU进行解密处理；和/或，所述用户设备根据所述完整性校验参数对接收到的PDU进行完整性校验处理。
具体地，所述用户设备根据所述完整性校验信息参数对需要发送的PDU进行完整性校验处理，具体有：用户设备使用上层提供的密钥计算出完整性校 验码，然后根据完整性校验码对接收到的PDCP PDU进行完整性校验码比对，如果完整性校验码相对应，则完成完整性校验成功。
在一示例中，所述EM包括计数值(COUNT)，所述COUNT是使用PDCP重配置之前所用密钥进行加密的最后一个数据包的COUNT。
具体地，现有LTE定义的EM格式如图3(1)～图3(3)所示。可见，现有的LTE定义的EM格式中包含有LSN域，且EM格式根据PDU序列号的不同长度而有不同格式。本方案中，为了方便管理使用统一的COUNT，如图4所示，该COUNT长度为32bit长度。
在一示例中，所述status report适用于确认模式(AM)和非确认模式(UM)。可使得在AM和UM中，发送端(本方案中的网络设备端)都可以确认收端(本方案中的用户设备端)已经正确接收到了EM。
在一示例中，所述EM适用于AM和UM。可见，通过EM使得在一个承载的变化不会影响其他承载。
