Description

异常数据传输方法、装置和系统
本申请要求于2017年4月26日提交中国专利局、申请号为201710284174.9、发明名称为“异常数据传输方法、装置和系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种异常数据传输方法、装置和系统。
背景技术
蜂窝物联网(Cellular Internet of Things，CIoT)是一种通过窄带物联网(Narrowband Internet of Things，NB-IoT)技术实现终端接入移动通信网络的物联网，目前可以接入到演进分组核心网(Evolved Package Core，EPC)，今后也可以接入下一代核心网，比如第5代(5th Generation，5G)核心网。
对于大量终端接入的应用场景，网络侧需要处理的数据量非常大，为了控制网络侧处理的数据量、提高无线通信效率、节省终端电量，网络侧需要对每个终端进行速率控制，即限制终端在单位时间内接收和发送数据包的数量。目前对终端进行速率控制的特性包括：服务公共陆地移动网络速率控制(Serving Public Land Mobile Network Rate Control，Serving PLMN Rate Control)和接入点名称速率控制(Access Point Name Rate Control，APN Rate Control)。对于APN速率控制，速率控制参数由网络侧分组数据网络网关(Packet Data Network GateWay，PDN GW)下发给用户设备(User Equipment，UE)，可应用于用户面和控制面中。如果UE发送的数据包超过限制数量，PDN GW将丢弃或延迟发送超限制的数据包。
在一些特殊的物联网应用场景中，例如工厂设备监控系统、分布式温度传感系统、地震监测网系统等，UE在检测到设备故障、火灾、地震等紧急情况时，要将这些紧急情况以异常数据(exception data)的形式发送到网络侧。由于涉及到故障灾害等紧急情况，需要保证这些异常数据具有较高的优先级，即使已经达到速率控制设定的最大上行数据数量，UE也不对异常数据实施APN速率控制，继续将其发送到网络侧。
现有技术中定义的APN速率控制只适用于空闲态的UE发送第一个异常数据。而对于连接态UE，在发送上行数据时，由于无需建立无线资源控制(Radio Resource Control，RRC)连接，导致PDN GW无法获知当前UE发送的用户数据包是异常数据还是正常数据，从而无法跳过APN速率控制，也即把该异常数据包当作正常的数据包来处理。因此当UE发送的数据包超过APN速率限制时，PDN GW会直接丢弃该异常数据包或延迟发送该异常数据包，导致网络侧无法对上报异常数据的异常情况进行优先及时处理。

本申请实施例应用的具体场景是：网络侧对UE发起APN速率控制，UE与网络侧同时执行APN速率控制，UE监测到紧急情况并上报异常数据。需要说明的是，本实施例以CIoT中的小数据包传输速率控制为例进行描述，但是也可以适用于未来5G网络中小数据包的速率控制场景下对异常数据的处理。本申请实施例适用于控制面上小数据传输的场景。
本申请实施例提供了一种异常数据传输方法，参照图5中所示，包括：
S101、UE在执行APN速率控制的情况下，确定有异常数据需要发送。
UE根据网络侧下发的APN速率控制参数(APN rate control parameters)来限制发送给该APN的上行用户数据包的数量。当UE发送给该APN的用户数据包已经达到设定的最大限制时，UE停止向该APN发送上行数据包。
S102、UE向第一核心网设备发送NAS消息。
即UE跳过APN速率控制的限制将异常数据通过NAS消息上报给网络侧。
该NAS消息包括上述异常数据和异常数据指示信息(exception data indication)，异常数据指示信息用于指示第一核心网设备该NAS消息中包括上述异常数据。
可选地，在达到APN速率控制的最大速率限制时，UE可以确定是否允许发送异常数据。UE可以根据之前网络侧下发的APN速率控制参数(APN rate control parameters)中的指示信息来判断在达到APN速率控制的最大速率限制时是否允许发送异常数据。
可选的，若UE处于空闲态，则NAS消息为控制面服务请求消息(Control Plane Service Request)。
可选的，若UE处于连接态，则NAS消息为数据传输消息(Data Transport)。
需要说明的是，该异常数据指示信息可以包括在NAS消息中新定义的信元(Information Element，IE)中，例如在数据传输消息中增加一个新信元用来指示异常数据；或者异常数据指示信息还可以为NAS消息中已有信元新定义的信元值，例如针对控制面服务请求消息的业务类型信元，定义一个新信元值用来指示异常数据；或者异常数据指示信息还可以包括在NAS消息中已有信元的比特位中，本申请实施例不做限定。
S103、第一核心网设备从UE接收NAS消息后，根据NAS消息中的异常数据指示信息获知NAS消息中包括异常数据。
S104、第一核心网设备通过第二核心网设备向第三核心网设备发送第一消息。
该第一消息中包括异常数据和异常数据指示信息，异常数据指示信息用于指示第三核心网设备该数据消息中包括上述异常数据。
第一核心网设备接收到包括异常数据指示信息的NAS消息后，获知收到的数据包为异常数据，然后将该异常数据封装在第一消息中，并在该第一消息中加入异常数据指示信息。该第一消息是核心网设备之间传递的消息，它可以是现有的协议消息，比如第4代(4th  Generation，4G)通信系统中的用户面GPRS隧道协议(GPRS Tunnelling Protocol User Plane，GTP-U)消息或Diameter协议消息，也可以是新引入的协议消息，比如第5代(5th Generation，5G)通信系统中可能选择的代表性状态传递(Representational State Transfer，RESTFul)协议消息或Diameter协议消息，本申请实施例不做限定。
需要说明的是，该异常数据指示信息可以包括在该第一消息中新定义的值域(Field)中，例如在GTP-U消息头中增加一个新值域用来指示异常数据；或者异常数据指示信息还可以为第一消息中已有值域新定义的值，例如针对GTP-U消息头中的消息类型值域，定义一个新值用来指示异常数据，或者针对GTP-U消息头中的扩展头类型值域，定义一个新值用来指示异常数据；或者异常数据指示信息还可以包括在第一消息中已有值域的比特位中，本申请实施例不做限定。
S105、第三核心网设备从第二核心网设备接收来自第一核心网设备的第一消息。该第一消息中包括异常数据和异常数据指示信息。在第三核心网设备执行APN速率控制且APN速率控制达到最大速率限制时，该第三核心网设备根据接收到的异常数据指示信息将异常数据发送给数据网络(Data Network,DN)。
第三核心网设备收到该第一消息后，根据异常数据指示信息，获知收到的数据包是异常数据，进而即使在UE发送的数据包数量超过APN速率控制的最大速率限制时，第三核心网设备也不执行APN速率控制，不会丢弃该异常数据包或延迟发送，而是将该异常数据发送给数据网络。
在4G通信系统中，第一核心网设备为MME，第二核心网设备为SGW，第三核心网设备为PDN GW；或者，在5G通信系统中，第一核心网设备为AMF，第二核心网设备为SMF，第三核心网设备为UPF。第一核心网设备与第三核心网设备间支持GTP-U协议。
