Description

通信方法、装置、系统、终端和接入网设备
本申请要求于2016年9月30日提交中国专利局、申请号为201610875317.9、申请名称为“通信方法、装置、系统、终端和接入网设备”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
本发明涉及通信技术领域，特别涉及一种通信方法、装置、系统、终端和接入网设备。
背景技术
为了保证服务质量，在现在的长期演进(英文：Long Term Evolution，简称：LTE)系统中，通常采用端到端的服务质量(英文：Quality of Service，简称：QoS)机制。在这种机制下，当终端发起需要保证QoS的业务时，需要为终端建立专用承载，以传输业务数据。
其中，专用承载由终端和演进型基站(英文：evolved Node B，简称：eNB)之间的无线承载以及eNB与网络侧设备之间的地面侧通道构成，专用承载的建立过程如下：终端在发起业务时，先通过默认承载与应用服务器进行交互，由应用服务器触发策略与计费规则功能(英文：Policy and Charging Rules Function，简称：PCRF)单元产生QoS参数，并将产生的QoS参数通知到移动性管理实体(英文：Mobility Management Entity，简称：MME)，MME再将QoS参数发送给eNB。eNB接收到QoS参数后，会根据接收到的QoS参数建立专用承载，然后终端才能在建立好的专用承载上发送业务数据。
由于终端需要等待分配QoS参数的过程完成，且根据该QoS参数建立的专用承载建立好后，才能发送业务数据，因此，上行业务的数据发送启动速度较慢，不能满足降低业务时延的要求。
发明内容
为了解决现有技术上行业务的数据发送启动速度较慢的问题，本发明实施例提供了一种通信方法、装置、系统、终端和接入网设备。所述技术方案如下：
第一方面，本发明实施例提供了一种通信方法，所述方法包括：
终端在发起业务之前，接收第一QoS信息；
所述终端在发起所述业务时，根据所述第一QoS信息，采用接入网设备为所述业务配置的无线资源，发送所述业务的数据，所述无线资源是接入网设备根据第二QoS信息配置的，所述第一QoS信息和所述第二QoS信息均是核心网控制面设备在所述终端发起所述业务之前为所述终端的所述业务配置的。
本发明实施例通过在终端发起业务之前，为终端分配QoS信息(包括第一QoS信息和第 二QoS信息)，并将分配的QoS信息发送给终端和接入网设备，在终端发起业务时，可以直接采用接入网设备根据已分配的QoS信息配置的无线资源发送数据，也就是说，接入网设备不需要等待终端发起业务时触发核心网设备分配的授权的QoS信息，而是根据在业务发起之前预先分配的QoS信息就可以为终端配置无线资源，而终端可根据对应的QoS信息采用配置好的无线资源发送业务的数据，从而可以缩短终端的业务启动的时间。
在第一方面的第一种可能的实现方式中，若接入网设备根据第二QoS信息预先为业务对应的数据包组配置了无线资源，则终端在发起业务时，可以直接采用接入网设备预先配置的无线资源发送所述业务的数据。
在第一方面的第二种可能的实现方式中，若接入网设备没有根据第二QoS信息预先为业务对应的数据包组配置无线资源，则终端可以在发起业务时，请求接入网设备为该业务配置无线资源，然后再采用接入网设备配置的无线资源发送所述业务的数据。因此，在这种实施方式中，所述方法还包括所述终端向所述接入网设备发送QoS请求信息，以使所述接入网设备根据所述QoS请求信息，为所述终端的所述业务配置无线资源。
其中，第一QoS信息包括第一预授权QoS信息和反射特性信息中的至少一种，所述反射特性信息包括用于表示能够根据业务的下行QoS参数获得上行QoS参数的指示信息和业务的下行QoS参数。在本发明实施例中，预授权QoS信息(包括第一预授权QoS信息和下文中的第二预授权QoS信息)是核心网控制面设备根据终端的签约信息或者根据常用业务(例如邮件、淘宝等)主动为终端配置的。
结合第二种可能的实现方式，在第三种可能的实现方式中，所述QoS请求信息包括上行QoS信息，若终端接收到业务的第一QoS信息包括第一预授权QoS信息和业务的反射特性信息两种，则终端可以根据实际需要选择按照哪种QoS信息来请求无线资源。也就是说，所述上行QoS信息可以包括所述第一预授权QoS信息的至少一部分，以请求接入网设备按照第二预授权QoS信息配置无线资源，或者所述上行QoS信息可以包括根据业务的下行QoS参数得到的QoS参数，以请求接入网设备按照业务的反射特性信息配置无线资源。
进一步地，终端可以根据接收到第一预授权QoS信息和业务的反射特性信息的先后顺序，确定按照哪种QoS信息来请求无线资源。具体地，终端可以采用后接收到的信息对应的上行QoS信息发送QoS请求信息。具体地，若所述终端先接收到所述第一预授权QoS信息后接收到所述反射特性信息，则所述上行QoS信息包括根据业务的下行QoS参数得到的QoS参数，若所述终端先接收到所述反射特性信息后接收到所述第一预授权QoS信息，则所述上行QoS信息包括所述第一预授权QoS信息的至少一部分。

实际应用中，所述终端可以采用控制面信令的方式发送所述QoS请求信息。

在第六种可能的实现方式中，所述终端根据所述第一QoS信息，采用接入网设备为所述业务配置的无线资源，发送所述业务的数据，可以包括以下两种方式：
第一种方式：终端采用所述第一QoS信息指示的包过滤器对所述业务的数据进行筛选；

采用确定出的所述无线承载将所述业务的数据发送给接入网设备。
进一步地，若终端是根据第一预授权QoS信息，发送业务数据，在一种实现方式中，所述第一预授权QoS信息可以包括至少一个数据包组的包过滤器和所述至少一个数据包组对应的QoS参数的标识。在另一种实现方式中，所述第一预授权QoS信息可以包括业务的应用层信息以及业务的QoS参数的标识、以及QoS参数的标识与业务的应用层信息的对应关系。其中，业务的应用层信息可以为应用程序ID，从而终端可以根据应用层信息为数据进行分组。
当所述第一预授权QoS信息包括至少一个数据包组的包过滤器和所述至少一个数据包组对应的QoS参数的标识时，所述终端根据所述第一预授权QoS信息，发送所述业务的数据，包括：终端采用所述第一预授权QoS信息指示的包过滤器对所述业务的数据进行筛选；终端将筛选出的数据包采用第一预授权QoS信息指示的包过滤器对应的无线承载发送给接入网设备。

其中，所述地面侧通道是按照每个PDU会话唯一对应一个地面侧通道的方式建立的。
在第二方面的第八种可能的实施方式中，所述第一接入网设备接收第二预授权QoS信息，包括：
所述第一接入网设备接收第二接入网设备发送的切换请求消息，所述切换请求消息包括所述第二预授权QoS信息。
结合第八种可能的实施方式，在第九种可能的实施方式中，所述切换请求消息携带第三指示信息和数据传输指示信息中的至少一种，所述第三指示信息用于指示数据包组是否 在源侧已经建立了无线承载，所述数据传输指示信息用于指示数据包组是否有数据已经传输或正在传输。
相应地，所述第一接入网设备根据所述第二预授权QoS信息为终端配置无线资源，包括：所述第一接入网设备根据以下信息中的至少一种确定是否为终端配置无线资源：所述第二接入网设备是否已经为数据包组建立了无线承载、所述第二接入网设备已经建立无线承载的数据包组是否已经传输过数据、所述第二接入网设备已经建立无线承载的数据包组是否正在传输数据。
当第一接入网设备根据切换请求消息中的第二预授权QoS信息为终端配置无线资源之后，所述方法还包括：

进一步地，所述切换准备成功消息和所述切换准备失败消息中携带切换切换失败的原因，所述切换失败的原因为以下原因之一：没有可用的无线资源、不支持预授权QoS的无线承载预建立、不支持QoS参数和地理区域不支持。
第三方面，本发明实施例还提供了一种通信方法，所述方法包括：
核心网控制面设备为终端的业务配置第一QoS信息和第二QoS信息，所述第一QoS信息和所述第二QoS信息是在所述终端发起所述业务之前配置的；
所述核心网控制面设备向所述终端发送所述第一QoS信息，并向接入网设备发送所述第二QoS信息。
在第三方面的一种可能的实现方式中，所述方法还包括：
核心网控制设备在区域更新流程或终端在不同的接入网设备之间切换的过程中更新所述第一QoS信息和所述第二QoS信息中的至少一个；
将更新后的所述第一QoS信息发送给所述终端，并将更新后的所述第二QoS信息中发送给所述接入网设备。
在第一方面、第二方面和第三方面中，该第一预授权QoS信息和第二预授权QoS信息是核心网控制设备为终端配置的，可以保存在终端的上下文中发送给终端和接入网设备。实际应用中，该第一预授权QoS信息可以通过非接入层消息直接发送给终端，也可以通过接入层消息经由接入网设备发送给终端。而第二预授权QoS信息可以通过接入层消息发送给接入网设备。
在终端发起业务之前，例如发送业务请求之前，为终端分配预授权QoS信息(包括第一预授权QoS信息和第二预授权QoS信息)，并将预授权QoS信息发送给终端和接入网设备，从而在终端发起业务时，接入网设备不需要等待从核心网设备获取授权的QoS信息，就可以为终端配置无线资源，终端即可采用配置好的无线资源发送业务的数据，可以缩短终端的业务启动的时间。
实现时，优选在现有的信令流程中，例如在PDU会话过程中或者在UE初始上下文建立过程中，将第一预授权QoS信息发送给终端以及把第二预授权QoS信息发送给接入网设备，从而可以减少QoS参数分配所需的信令，节省网络侧的信令开销。
可选地，第一预授权QoS信息和第二预授权QoS信息的内容可以相同，也可以不同。当第一预授权QoS信息与第二预授权QoS信息不同时，第一预授权QoS信息可以是第二预授权QoS信息的一部分，或者第一预授权QoS信息和第二预授权QoS信息有部分重叠。
进一步地，第一预授权QoS信息和第二预授权QoS信息均可以包括一套或多套QoS信息，每套QoS信息对应一个数据包组，下文中第一预授权QoS信息包含的内容和第二预授权QoS信息包含的内容均是每套QoS信息包含的内容。通过在第一预授权QoS信息中包含多套QoS信息，在第二预授权QoS信息中包含多套QoS信息，可以一次将多个数据包组对应的QoS信息发送给终端和接入网设备，与现有的终端请求建立专用承载，根据终端的请求每次为一个数据包组配置QoS参数并发送给终端和接入网设备相比，可以节省网络信令开销。
在第一方面、第二方面和第三方面中，反射特性信息也是下行业务建立时，核心网控制面设备通知接入网设备的。具体地，核心网控制面设备会通知接入网设备业务的下行QoS参数，并且指示该业务具备反射特性，即可以根据业务的下行QoS参数获得业务的上行QoS参数。然后，接入网设备再将业务的反射特性信息发送给终端。
进一步地，接入网设备将业务的反射特性信息通知到终端可以采用以下两种方式中的一种：
方式一、通过用户面的方式通知到终端。例如，在PDCP层的数据包头中携带所述反射特性信息。或者，还可以在其他协议层的头携带，例如RLC层、MAC层的头中携带。
方式二、通过控制面的方式通知到终端。例如，通过RRC消息发送到终端，在消息中显示指示业务具备反射特性(即能够根据下行业务的QoS参数获得上行业务的QoS参数)。或者，还可以采用隐式的方式，通过无线承载的上行配置的方式来指示业务具备反射特性，即若接入网设备在反射特性信息中携带了上行无线承载的配置，则表示该业务具备反射特性。
可选地，结合第一方面、第二方面和第三方面，在一些实施例中，为了节省通信资源，在业务终止时，接入网设备和终端都需要释放相关的资源配置。
在一种可选的实施方式中，可以由终端来检测业务是否终止，相应地，所述方法还包括：所述终端监测所述业务是否终止；当所述终端监测到所述业务终止时，向所述接入网设备发送业务终止请求。相应地，当第一接入网设备接收到终端发送的业务终止请求，会根据所述终端的业务释放请求释放为所述业务分配的无线资源，并通知所述终端释放所述业务的无线资源的配置；
其中，终端检测业务终止可以采用以下方式：
当所述业务的数据量为零或低于设定门限时，所述终端启动定时器，若定时器超时时，所述业务的数据量未增加，则检测到所述业务终止；若定时器超时之前，业务的数据量增加，则重置定时器，在下一次业务的数据量为零或低于设定门限时，重新启动定时器。
或者，终端还可以监测是否收到应用层的业务结束指令，当收到业务结束指令时，表示业务终止。
可选地，所述定时器是由核心网控制面设备设置的，所述定时器携带在所述第一预授权QoS信息中发送给所述终端(例如通过NAS消息发送给终端)；或者，所述定时器是由所述接入网设备设置的，所述定时器通过无线资源控制RRC消息或用户面控制协议数据单元PDU发送给所述终端的。
可选地，终端向接入网设备发送业务终止请求，可以采用控制面或用户面的方式。其中，控制面的方式可以是通过RRC消息的方式，该RRC消息中包括需要终止的数据包组的QoS信息和请求业务终止的指示信息，QoS信息是QoS参数的标识。用户面的方式可以是通过指示业务结束的数据包的方式。例如，在PDCP层生成PDCP PDU，将其设置为endmarker PDU，表示该业务的结束。或者，在该PDCP PDU中携带QoS参数的标识和业务终止指示信息，或者，采用PDU本身格式指示业务终止。另外，还可以通过RLC PDU或MAC PDU的方式来通知接入网设备，采用RLC PDU和MAC PDU的方式与PDCP PDU的方式类似，在此不再赘述。
在另一种可选的实现方式中，可以由接入网设备来检测业务是否终止，相应地，第二方面提供的所述方法还包括：所述接入网设备监测所述业务是否终止；当所述接入网设备监测到所述业务终止时，释放为所述业务分配的无线资源，并通知所述终端释放所述业务的无线资源的配置。

可选地，处理器41用于执行应用程序模块45中的各个模块，实现如下图图5、图6、图7、图8、图9a-9b、图10和图11中由核心网控制面设备所需要执行的步骤。
此外，存储器42是一种计算机可读存储介质，可以由任何类型的易失性或非易失性存储设备或者它们的组合实现，如静态随时存取存储器(SRAM)，电可擦除可编程只读存储器(EEPROM)，可擦除可编程只读存储器(EPROM)，可编程只读存储器(PROM)，只读存储器(ROM)，磁存储器，快闪存储器，磁盘或光盘。
参见图5，其示出了本发明实施例提供的一种通信方法，该方法可以采用图1所示的系统实现。在图5所示实施例中，以根据预授权QoS信息配置无线资源为例进行说明，该方法包括：
S501：核心网控制面设备发送第一预授权QoS信息给终端，并发送第二预授权QoS信息给第一接入网设备。
其中，核心网控制面设备可以根据终端的签约信息(例如，从归属签约服务器(英文：Home Subscriber Server，简称：HSS)获取到的终端的签约信息)来为终端配置预授权QoS信息(包括第一预授权QoS信息和第二预授权QoS信息)。此外，核心网控制面设备还可以针对常用业务(例如邮件、淘宝等)，为终端配置预授权QoS信息。两种情况可以结合。
在一种实现方式中，核心网控制面设备通过接入层(英文：Access Stratum，简称：AS)消息发送第二预授权QoS信息给第一接入网设备，第一接入网设备再通过AS消息将第一预授权QoS信息发送给终端。在另一种实现方式中，核心网控制设备通过AS消息发送第二授权QoS信息给第一接入网设备，核心网控制设备通过非接入层(英文：Non Access Stratum，简称：NAS)消息将第一授权QoS信息发送给终端，如图5所示。
实现时，该第一和第二预授权QoS信息可以在协议数据单元(英文：Protocol Data Unit，简称：PDU)会话建立过程中发送，例如可以携带在会话建立响应消息中发送，则核心网控制面设备可以在接收到会话建立请求消息时，为终端配置预授权QoS信息。需要说明的是，PDU会话建立过程也可以称为公用数据网络(英文：Public Data Network，简称：PDN)连接建立过程。或者，该第一和第二预授权QoS信息也可以在初始UE上下文建立过程中发送。
进一步地，第一预授权QoS信息和第二预授权QoS信息的内容可以相同，也可以不同。当第一预授权QoS信息与第二预授权QoS信息不同时，第一预授权QoS信息可以是第二预授权QoS信息的一部分，或者第一预授权QoS信息和第二预授权QoS信息有部分重叠。
具体的，第一预授权QoS信息包括至少一个QoS参数的标识，每个QoS参数的标识可以作为索引对应着数据包组的QoS参数(即为数据包组对应的QoS参数的索引)。实现时，QoS参数的标识与QoS参数的对应关系，一种方式是标准定义的，即标准中定义多套QoS参数(例如每一套QoS参数可包含优先级、时延、丢包率)，并且为每套QoS参数指定编号，该编号即可作为QoS参数的标识，例如，QoS参数的标识1对应标准中的第一套QoS参数；另一种方式是核心网控制面设备配置的，作为索引对应着若干QoS参数的集合(例如QoS参数的标识2对应着核心网配置的一套优先级、时延、丢包率、保证速率等参数的集合)。两种对应关系可以单独使用，可以同时存在。
可选地，第一预授权QoS信息还可以包括：数据包组的网络切片(英文slice)标识信息，所述slice标识信息包含下述多项中的至少一项：slice id、slice type、租户类型、租户标识、网络功能标识等。
在第一种实现方式中，第一预授权QoS信息还包含包过滤器，每一包过滤器对应着一个QoS参数的标识。包过滤器可以用于根据IP5元组信息或者根据源地址和目标地址筛选数据包，得到数据包组。其中，IP5元组信息是针对IP数据包的，可以包括源IP地址、目标IP地址、源端口、目标端口和协议号中的一项或多项。源地址和目标地址是针对非IP数据包(例如以太(英文：Ethernet)帧)的。例如，可以通过IP 5元组包过滤器过 滤得到一组IP数据包；又例如，可以通过以太帧的源地址和目的地址中的至少一个的包过滤器过滤得到一组以太帧。
在第二种实现方式中，第一预授权QoS信息还包括QoS参数的标识与应用层信息的对应关系。其中，应用层信息可以为应用层的应用程序ID等信息，从而终端可以通过应用层的信息来对数据包进行分组，并匹配到QoS参数的标识。
进一步地，第一预授权QoS信息中可以包括一套或多套QoS信息，每套QoS信息包括一个数据包组的QoS参数的标识及对应的其他信息(例如业务的应用层信息或包过滤器或QoS参数)。通过在第一预授权QoS信息中包含多套QoS信息，可以一次将多个数据包组对应的QoS信息发送给终端，与现有的终端请求建立专用承载，根据终端的请求每次为一个数据包组配置QoS参数并发送给终端相比，可以节省网络信令开销。
第二预授权QoS信息可以包括前述第一预授权QoS信息的内容；或者包括前述第一预授权QoS信息的一部分内容，例如，第一预授权QoS信息包括QoS参数的标识和对应的包过滤器(即前述第一预授权QoS信息的第一种实现方式)，而第二预授权QoS信息只包括QoS参数的标识而不包括包过滤器。
需要说明的是，在QoS参数的标识和QoS参数的对应关系是标准定义的情况下，接入网设备可以预先配置有该对应关系，则第二预授权QoS信息中可以包括数据包组对应的QoS参数，也可以不包括数据包组对应的QoS参数。而在QoS参数的标识和QoS参数的对应关系是核心网控制面设备为终端配置的情况下，第二预授权QoS信息中必须包括QoS参数的标识对应的QoS参数。
具体的，QoS参数可以包括优先级、丢包率、时延、保证速率(英文：Guaranteed Bit Rate，简称：GBR)、最大速率、请求速率、单个数据包的丢弃优先级、单个数据包的优先级、会话的速率、分配保留优先级(英文：Allocation and Retention Priority，简称：ARP)等中的一项或多项。其中，保证速率是指该数据包组需要网络保证提供的速率，最大速率是指该数据包组传输的最大速率。请求速率是指非(英文：non)GBR的业务请求网络提供的速率，一般是指该数据包组为满足业务需求的速率。会话的速率是指该PDU会话中为所有非保证速率的数据包组提供的速率总和的最大值。分配保留优先级表示数据包组抢占和被抢占的级别。
进一步地，实现时，对于保证速率业务，QoS参数通常至少包括优先级、丢包率、时延和保证速率。对于非保证速率业务，QoS参数通常至少包括优先级、丢包率和时延。
可选地，第二预授权QoS信息还可以包括聚合QoS信息，聚合QoS信息用于指示多个数据包组的整体QoS的需求。例如多个数据包组的最大聚合速率，该最大聚合速率表示多个数据包组传输的最大速率。实现时，这多个数据包组可以属于同一个业务；进一步地，该业务可以是非保证速率业务。或者，这多个数据包组可以属于同一网络切片(英文：slice)，进一步地，这多个数据包组可以是该slice下的所有non GBR业务的数据包组的最大聚合速率，例如网络切片-聚合最大比特速率(英文：slice-Aggregate Maximum Bit Rate，简称：slice-AMBR)。其中，网络切片为支持特定用例通信业务需求的逻辑网络功能组合。网络切片使用逻辑资源，而不是物理资源，帮助运营商提供以业务为基础的网络架构。
第一接入网设备在后续数据包组的数据包发送过程中，根据聚合QoS信息进行速率控制，使得数据包组的整体最大速率不超过聚合QoS信息中的最大聚合速率。例如，通过上 行或下行的调度处理，进行速率控制。
进一步可选地，第二预授权QoS信息中还可以包括第一指示信息，该第一指示信息用于指示第一接入网设备接收到第二预授权QoS信息后，是否为对应的数据包组预先配置无线资源。其中，预先配置无线资源是指接收到预授权QoS信息后，立即配置无线资源。
在一种实现方式中，该第一指示信息可以是基于每个数据包组分别配置的，例如指示数据包组1需要预先配置无线资源，而数据包组2不需要预先配置无线资源。或者，该第一指示信息可以按照数据包组的QoS参数来设置，具体地，可以按照QoS参数的类别、优先级、时延等设置，例如，按照GBR业务和non GBR业务分别设置是否需要预先配置无线资源(类别)，或者指示对高优先级的数据包组需要预先配置无线资源(优先级)，或者指示对数据时延要求比较苛刻(例如时延值低于设定值)的数据包组需要预先配置无线资源(时延)。
进一步的，对于需要预先建立无线资源的数据包组，该第一指示信息还可以指示预先建立无线资源的优先级，接入网设备可以根据网络情况来选择性的为数据包组建立无线资源。例如，在网络负荷较高时，可只为高优先级的数据包组建立无线资源，而在网络负荷较轻时，可为低优先级的数据包组也建立无线资源。
从而可以实现灵活的预授权QoS的数据包组的无线资源建立。预先建立无线资源的优先级的设置可以基于数据包组的QoS参数中的一项或多项来设置，例如可以根据QoS参数的类别、优先级、时延等参数中的一项或多项来设置。
实现时，该第一指示信息可以仅指示需要预先配置无线资源的数据包组，对于没有明确指示需要预先配置无线资源的数据包组，第一接入网设备可以默认为不需要马上建立无线资源。
其中，第一指示信息的有效范围可以是上行业务、下行业务、或者上行和下行业务。例如，若第一指示信息的有效范围是上行业务时，预先为数据包组配置上行无线资源，而不预先配置下行无线资源。
在另一种实现方式中，可以网络协商或者协议约定一种或几种数据包组需要预先配置无线资源，或者某一种或几种数据包组不需要预先配置无线资源，此时，预授权QoS信息可以不包括第一指示信息。进一步地，可以默认所有的预授权QoS信息都需要预先配置无线资源，或者默认所有的预授权QoS信息都不需要预先配置无线资源。
可选地，若数据在第一接入网设备和核心网用户面设备之间需要建立数据通道，则预授权QoS信息还可以包括第二指示信息，第二指示信息用于指示是否在第一接入网设备和核心网用户面设备之间建立数据通道，即建立地面侧通道，该数据通道可以为承载或隧道。
进一步地，若数据在第一接入网设备和核心网用户面设备之间无需建立数据通道或者只需要每个终端或每个PDU会话建立一个数据通道，例如，第一接入网设备和核心网用户面设备之间已经为该终端或者该终端的该PDU会话建立过数据通道，则第二预授权QoS信息中无需包括第二指示信息。
实现时，上述第一指示信息和第二指示信息可以为同一指示信息，即该指示信息同时指示是否建立无线承载和地面侧的承载或数据通道。
进一步地，第二预授权QoS信息还可以包括生效范围信息，该生效范围信息用于指示第二预授权QoS信息生效的地理区域，地理区域可以用位置区列表和或路由区列表的方式表示。
S502：第一接入网设备接收到第二预授权QoS信息，并根据第二预授权QoS信息配置无线资源。
在本实施例中，配置无线资源，是指为数据包在空口的传输分配无线资源，以进行上行数据的传输，可以包括建立无线承载(英文：Radio Bearer，简称：RB)以及无线承载与数据包组的映射关系(适用于需要为数据包组新建立无线承载的情况)，或者只包括配置数据包组和无线承载的映射关系(适用于将数据包组映射到已有无线承载上的情况)。该无线承载用于空口的数据传输，终端可以根据数据包组和无线承载的映射关系，将数据包组在对应的无线承载上进行发送。进一步的，接入网设备可以根据无线资源管理(英文：Radio Resource Management，简称：RRM)策略决定为该QoS参数的数据包组建立一个新的无线承载或者映射到一个现有无线承载上。
其中，建立无线承载，包括在空口建立或修改无线承载，其中，RB对应的协议栈包括分组数据汇聚协议(英文：Packet Data Convergence Protocol，简称：PDCP)、无线链路控制层协议(英文：Radio Link Control Protocol，简称：RLC)、逻辑信道(英文：Logical Channel，简称：LCH)参数配置，第一接入网设备为每一层协议栈配置相关参数，表示无线承载(英文：Radio Bearer，简称：RB)的传输特性，以适应QoS参数。
进一步的，第一接入网设备配置无线资源过程中，可以参考数据包组的slice标识信息、会话信息其中的一项或多项，例如，第一接入网设备将归属不同slice的数据包组映射到不同的无线承载中。还可以将归属不同会话的数据包组映射到不同的无线承载中。
进一步的，接入网设备可以配置数据包组和无线承载的绑定关系，其中，在同一无线承载中，可只绑定同一PDU会话的数据包组。
其中，无线承载的配置信息包括PDCP、RLC、LCH参数配置。
所述PDCP参数配置可以包含丢弃定时器(英文：discardTimer)、头压缩、重排序定时器、SN长度等其中的一项或多项；
所述RLC参数配置可以包含：上下行RLC模式、Poll的重传定时器、状态限制定时器(英文：t-StatusProhibit)、Poll PDU、Poll Byte、最大重传次数、重排序定时器(英文：t-Reordering)、SN长度等其中的一项或多项；
所述MAC层的逻辑信道参数配置可以包含：优先级(英文：priority)、名义速率(英文：prioritised Bit Rate)、桶大小(英文：bucket Size Duration)、归属逻辑信道组(英文：logical Channel Group)等其中的一项或多项。
数据包组与无线承载的映射关系可以为以下关系中的任意一种：数据包组的标识和RB的映射关系(例如前述QoS参数的标识和RB的映射关系)、包过滤器和RB的映射关系、数据包组的优先级和RB的映射关系(不同优先级的数据组映射到不同的RB)、或者数据包组对应的业务类别和RB的映射关系，其中，数据包组对应的业务类别和RB的映射关系包括但不限于：GBR和non GBR的数据包组映射到不同的RB、或者所有的non GBR的数据包组映射到某一设定的RB、或者同一PDU会话的non GBR业务数据包组映射到同一RB(例如，该映射关系可以是non GBR业务数据包组的APN和DRB ID的映射关系，或者non GBR业务数据包组的IP地址和DRB ID的映射关系，或者，non GBR业务数据包组的隧道ID和DRB ID的映射关系)。或者，数据包组与无线承载的映射关系还可以为前述映射关系中至少两种的组合，例如，结合包过滤器和优先级得到的数据包组映射到某一RB。
此外，第一接入网设备还可以在配置无线资源过程中，参考数据包组的slice标识信 息、会话信息其中的一项或多项，例如，第一接入网设备将归属不同slice的数据包组映射到不同的无线承载中。还可以将归属不同会话的数据包组映射到不同的无线承载中。则相应地，数据包组与无线承载的映射关系还可以包括会话与无线承载的映射关系或者slice与无线承载的映射关系。
需要说明的是，若第一接入网设备将该数据包组对应到一个已经存在的无线承载上时，则该步骤S502只需要建立无线承载与数据包组的映射关系，而无需建立或修改无线承载。
对于下行业务，第一接入网设备自行配置数据包组和RB的映射关系。
具体的，该步骤S502可以包括：
当第二预授权QoS信息中包括第一指示信息，且第一指示信息指示需要为对应的数据包组预先配置无线资源时，立即根据第二预授权授权QoS信息中的QoS参数为对应的数据包组配置无线资源；
当第二预授权QoS信息中包括第一指示信息，且第一指示信息指示不需要或者当第二预授权QoS信息中不包括指示需要为对应的数据包组预先配置无线资源的第一指示信息时，为对应的数据包组预先配置无线资源时，在终端发起业务(例如发送业务请求)时，为数据包组配置无线资源。
S503：终端接收第一预授权QoS信息。
终端接收到第一预授权QoS信息之后，会保存第一预授权QoS信息，以便于后续发起业务时，根据第一预授权QoS信息发送业务数据。因此，该步骤S503在终端发起业务之前执行，即在终端发送业务请求之前执行。
可选地，核心网控制面设备可以通过位置区和或路由区更新等区域更新流程对预授权QoS信息进行更新，更新预授权QoS信息(包括前述第一预授权QoS信息和第二预授权QoS信息中的至少一个)中的部分或全部信息。终端和第一接入网设备收到更新的预授权QoS信息，对本地保存的预授权QoS信息进行更新。
S504：第一接入网设备将无线资源的配置信息发送给终端。
其中，无线资源配置信息包括无线承载的配置信息、以及数据包组与无线承载的映射关系；或者，无线资源配置信息包括数据包组与无线承载的映射关系。
可选地，无线资源的配置信息还可以包括分组数据包的数据传输方式配置信息，数据传输方式包括基站调度方式和终端竞争方式，当数据传输方式为终端竞争方式时，无线资源的配置信息还包括竞争的资源配置，例如竞争的公共信道配置、竞争的规则配置等。公共信道配置可以为信道的资源配置，例如公共信道对应的不同协议层的配置和公共信道对应的时频域资源配置信息中的一种或多种，竞争的规则可以包括终端进行竞争、竞争失败回退随机时间后再次竞争等规则中的一种或多种。
S505：终端接收无线资源的配置信息。
终端接收并保存无线资源的配置信息，以便后续采用相应的无线资源发送业务数据。
需要说明的是，步骤S503和步骤S505之前没有先后顺序。
S506：第一接入网设备在第一接入网设备和核心网用户面设备之间建立数据通道。
具体的，第一接入网设备和核心网控制面设备交互数据通道建立的信息，进行数据通道的建立。实现时，第一接入网设备和核心网用户面设备之间的数据通道可以在PDU会话建立过程中建立。
需要说明的是，当第二预授权QoS信息中包括第二指示信息，且第二指示信息指示需 要为数据包组预先建立数据通道时，该步骤S506需要在第一接入网设备接收到第二预授权QoS信息后立即执行。
该数据通道可以是按照每一PDU会话对应一个数据通道的方式建立的，即每个PDU会话唯一对应一个数据通道，也可以是按照每一终端对应一个数据通道的方式建立，即每个终端唯一对应一个数据通道。
第一接入网设备保存RB和数据通道的对应关系，核心网用户面设备保存数据通道和包过滤器之间的映射关系。
S507：终端在发起业务时，根据第一预授权QoS信息，发送该业务的数据。
具体的，该步骤S507可以包括：
当终端有业务数据要发送时，采用包过滤器对业务数据进行过滤；
根据无线资源的配置信息中的数据包组和无线承载的映射关系，将筛选出的数据包采用对应的无线承载发送给接入网设备。
在一种实现方式中，可以根据数据包组和无线承载的映射关系，直接确定对应的无线承载，例如，当数据包组和无线承载的映射关系是数据包组的标识和无线承载的映射关系时。
在另一种实现方式中，需要根据数据包组和无线承载的映射关系，间接确定对应的无线承载，例如无线资源的配置信息中，携带的是QoS参数与无线承载的映射关系(例如数据包组的优先级和RB的映射关系、或者数据包组的时延和RB的映射关系)，此时，根据无线资源的配置信息中的数据包组和无线承载的对应关系，将筛选出的数据包采用对应的无线承载发送给接入网设备，包括：
根据筛选出的数据包通过的包过滤器确定包过滤器对应的QoS参数的标识；获取该QoS参数的标识对应的QoS参数；根据获取到的QoS参数确定数据包组对应的无线承载。
或者，该步骤S507可以包括：
确定业务对应的无线承载；
采用确定出的无线承载将所述业务的数据发送给第一接入网设备。其中，业务对应的无线承载，是根据无线资源的配置信息中的数据包组和无线承载的对应关系确定的。
可选地，当无线资源的配置信息中还包括数据传输方式时，将数据包发送给第一接入网设备可以包括：
当终端的数据传输方式为基站调度方式时，终端根据数据包组和RB的映射关系，选择出数据包组对应的RB，并在该RB上将数据包发送给第一接入网设备；或者，当终端的数据传输方式为竞争方式时，终端在公共信道上进行竞争，竞争成功则在对应资源上进行数据发送。
实现时，可以将通过包过滤器的数据包组称为一个流(英文：flow)，则上述数据包组和RB的映射关系还可以称为flow和RB的映射关系。
S508：第一接入网设备接收终端发送的数据，并将数据转发到核心网用户面设备。
具体的，接入网设备通过接入网设备和核心网用户面设备之间的数据通道将接收到的数据包发送给核心网用户面设备。接入网设备和核心网用户面设备之间的数据通道可以在PDU会话建立过程中建立。
具体地，该步骤S508包括：第一接入网设备将数据包采用对应的数据通道发送给核心网用户面设备。
进一步地，对于数据通道按照每一PDU会话对应一个数据通道的方式建立的情况，该步骤S508采用以下方式实现：
接入网设备获取数据包对应的PDU会话信息；
将数据包通过PDU会话信息对应的数据通道发送给核心网用户设备。
具体的，接入网设备获取数据包对应的PDU会话信息可以有采用以下方式：
在核心网控制面设备通知到接入网设备的第二预授权QoS信息，或者核心网控制面设备通知到接入网设备的授权QoS信息中包含会话信息，则可以从第二预授权QoS信息或授权QoS信息中获取数据包对应的PDU会话信息。
进一步地，第二预授权QoS信息或授权QoS信息中可以是显示的或隐式的包含PDU会话信息。例如在会话建立过程中的第二预授权QoS信息可以隐式的包含会话信息，根据不同的会话建立过程关联到具体的会话信息。而在核心网控制面设备通知授权QoS到接入网设备的过程中，可以在QoS信息中显式的携带会话信息。
接入网设备可以对数据包进行过滤，得到其对应的QoS参数，根据QoS参数得到会话信息，从而将数据包映射到对应的数据通道上，完成路由操作。其中，在会话建立过程中，接入网设备和核心网用户面设备之间会建立该会话的数据通道，用于该PDU会话在地面侧的数据传输。
例如，数据包组1属于会话1，数据包组2属于会话2，接入网设备收到若干上行数据包，根据数据包组1的包过滤器1对所述数据包进行过滤得到数据包组1的数据包，将数据包组1的数据包投递到会话1对应的数据通道1中，从而完成路由。根据数据包2的包过滤器2对所述数据包进行过滤得到数据包组2的数据包，将数据包组2的数据包投递到会话2对应的数据通道2中，从而完成路由。进一步的，接入网设备可以对会话1的所有数据包组的包滤波器进行合并，得到会话1的包过滤器组，接入网设备将使用会话1的包过滤器组进行过滤得到的数据包投递到会话1对应的数据通道1中，从完成路由。
进一步的，若在同一无线承载中，只绑定同一会话的数据包组。即若会话1的若干个数据包组映射到同一无线承载中，则接入网设备将该无线承载的上行数据包投递到会话1对应的数据通道1中，完成路由，不用进行包过滤操作。
此外，对于下行业务，第一接入网设备自行配置数据包组和RB的映射关系，第一接入网设备在发送下行数据时，通过数据包组和RB的映射关系，选择出数据包组对应的RB，并通过选择出的RB将数据发送给终端。
在本实施例中，在终端发起业务之前，为终端分配预授权QoS信息(包括第一预授权QoS信息和第二预授权QoS信息)，并将预授权QoS信息发送给终端和接入网设备，从而在终端发起业务时，接入网设备不需要等待从核心网设备获取授权的QoS信息，就可以为终端配置无线资源，终端即可采用配置好的无线资源发送业务的数据，可以缩短终端的业务启动的时间，并且可以节省核心网侧的信令开销。此外，在接入网设备获取到预授权QoS信息之后立即为终端配置无线资源的情况下，可以使终端在数据包发送之前，进入链接态，建立好无线承载和/或地面侧的数据通道，在终端有上行数据需要发送时，可以直接在预先建立好的无线承载上进行数据的发送，从而进一步提高了数据发送的启动速度，提高了用户体验。
参见图6，其示出了本发明实施例提供的一种通信方法，该方法采用图1所示的系统 实现。在图6所示实施例中，以根据切换过程中的预授权QoS信息配置无线资源为例，对本发明实施例进行详细说明，该方法包括：
S601：第二接入网设备发送切换请求消息给第一接入网设备。
其中，第二接入网设备也可以称为源侧接入网设备，第一接入网设备也可以称为目标侧接入网设备。第一接入网设备第二接入网设备之间的切换过程消息的发送和接收可以通过两者之间的直接接口进行(对等实体间进行的切换过程)，也可以通过第三方进行转发，例如通过核心网控制面设备(通过核心网进行的切换过程)。
该切换请求消息包括预授权QoS信息，切换请求消息中的预授权QoS信息可以包括图5所示实施例中的第二预授权QoS信息的部分或全部，例如，可以只包含步骤S501中的QoS参数的标识及其对应的QoS参数，或者可以包含QoS参数的标识及其对应的QoS参数和QoS参数对应的包过滤器，或者，还可以包含第一指示信息。
实现时，核心网控制面设备可通过切换流程对预授权QoS信息进行更新，例如通过切换请求消息，更新预授权QoS信息中的部分或全部信息，发送到目标侧接入网设备和或终端。终端和目标侧接入网设备收到更新的预授权QoS信息，对本地保存的预授权QoS信息进行更新。其中，终端通过切换过程中的空口消息得到更新的预授权QoS信息。
进一步的，切换请求消息中还可以包括第三指示信息，该第三指示信息用于指示数据包组是否在源侧已经建立了无线承载。
在一种实现方式中，该第三指示信息可以是一个针对每一数据包组的显示指示，例如，携带一个QoS参数的属性信息，该属性信息用于指示是否为数据包组配置了无线资源，即源侧是否已经建立了该数据包组和无线承载的对应关系。在该实现方式中，切换请求消息中还可以包括数据传输指示信息，该数据传输指示信息用于指示在源侧已经配置了无线资源的数据包组是否有数据已经传输，或者正在传输。
在另一种实现方式中，第三指示信息还可以是一个隐式指示，例如，若切换请求消息中携带了数据包组和无线承载的对应关系，则表明在源侧已经为该套QoS参数对应的数据包组配置了无线资源，若切换请求消息中没有携带数据包组和无线承载的对应关系，则表明在源侧没有为该套QoS参数对应的数据包组配置无线资源。在该实现方式中，切换请求消息中也可以包括数据传输指示信息，该数据传输指示信息用于指示在源侧已经配置了无线资源的数据包组是否有数据已经传输，或者正在传输。
在另一种实现方式中，切换请求消息中可以不包括第三指示信息和数据传输指示信息，而采用切换过程中的其他消息携带第三指示信息和数据传输指示信息。例如，在源侧接入网设备发送给目标侧接入网设备的携带序列号状态报告(英文：Serial Number status report，简称：SN status report)的消息中，可只携带已经建立了数据包组和无线承载的映射关系的数据包组的SN status，所述SN status是指上行/下行(英文：uplink/downlink)PDCP SN and超帧号(英文：Hyper Frame Number，简称：HFN)status。目标侧接收到携带SN status report的消息，可以获知哪些数据包组已经建立了无线承载。若数据包组的PDCP SN and HFN均为0，则说明没有数据在传输。即将PDCP的SN和HFN号作为隐式的第三指示信息和数据传输指示信息。
S602：第一接入网设备接收该切换请求消息，并根据切换请求消息中的预授权QoS信息确定进行接纳请求的判决，以确定是否接纳切换请求消息中请求的无线资源。
其中，接纳切换请求消息中请求的无线资源，是指按照切换请求消息中请求的无线资 源为终端配置无线资源，配置无线资源的具体实现可以参见步骤502，在此省略详细描述。
具体的，第一接入网设备可以以下信息中的一种或多种作为接纳判决算法的输入，来进行接纳请求的判决：
预授权QoS信息中的每个数据包组对应的QoS参数、QoS参数对应的数据包组是否已经配置无线资源、QoS参数对应的数据包组是否已经发送过数据、QoS参数对应的数据包组是否正在发送数据。
例如，第一接入网设备在接纳判决时，可以只考虑已经配置了无线资源的数据包组，根据所述数据包组的QoS参数，结合目标侧的资源状态，来决定是否接纳所述的在源侧已经建立无线承载的数据包组。又例如，目标侧网络资源紧张时，可以只考虑有数据发送的数据包组的资源请求。
S603：第一接入网设备向第二接入网设备发送切换响应消息，切换响应消息可以为切换准备失败消息或切换准备成功消息。
具体地，当第一接入网设备确定不接纳切换请求消息中请求的全部资源时，发送切换准备失败消息，该切换准备失败消息用于指示切换请求消息中请求的资源中的全部资源接纳失败；当第一接入网设备确定接纳切换请求消息中请求的全部资源或部分资源时，发送切换准备成功消息。其中，切换请求消息中请求的资源中的部分接纳失败，可包含预授权QoS信息中部分需要预先建立无线承载的数据包组在第一接入网设备接纳失败。
进一步地，该切换准备失败消息中还可以携带切换失败的原因。可以针对切换请求的每一数据包组给出一个失败原因。失败原因包括但不限于没有可用的无线资源、不支持预授权QoS的无线承载预建立、不支持QoS参数、地理区域不支持等。其中地理区域不支持，是指该业务在目标接入网设备的目标小区中不支持，例如某些业务只有特定的生效地理区域。不支持QoS参数，是指该QoS参数对应的业务在目标接入网设备中无法支持。
进一步地，该切换准备成功消息中还可以携带切换失败的原因。更进一步地，可以针对资源准备失败的每一数据包组给出一个失败原因。例如，携带一个列表，列表中包括资源准备失败的数据包组的标识和对应的失败原因。失败原因包括但不限于没有可用的无线资源、不支持预授权QoS的无线承载预建立、不支持QoS参数、地理区域不支持等。其中地理区域不支持，是指该业务在目标接入网设备的目标小区中不支持，例如某些业务只有特定的生效地理区域。不支持QoS参数，是指该QoS参数对应的业务在目标接入网设备中无法支持。
此外，切换准备成功消息中还包括资源准备成功的数据包组的相关资源配置信息。
S604：第二接入网设备接收切换响应消息，并根据切换响应消息确定是否发起切换执行。
具体的，若第二接入网设备接收到切换准备成功消息，第二接入网设备可以发起切换执行，将终端切换到目标小区中，目标小区为第一接入网设备提供的小区。
进一步的，第二接入网设备可以根据其中接纳的源侧请求的资源情况，决定不发起切换执行。例如目标侧只接受了部分业务的资源请求，而源侧决定不发起切换执行。或者，源侧还可以根据目标侧接收的业务类型，例如是授权业务还是预授权业务，来决定是否发起切换。
S605：当第二接入网设备确定发起切换执行时，第二接入网设备将第一接入网设备发送的资源准备成功的数据包组的无线资源的配置信息发送给终端。
无线资源的配置信息的具体内容可以参见前述步骤S504，在此省略详细描述。
S606：终端接收无线资源的配置信息。
在该步骤S606中，终端会接收并保存无线资源的配置信息。
S607：终端在发起业务时，根据第一预授权QoS信息，采用第一接入网设备配置的无线资源，将该业务的数据发送给第一接入网设备。
该步骤S607的具体实现过程可以参见步骤S507，在此省略详细描述。
S608：第一接入网设备接收终端发送的数据，并将数据发送到核心网用户面设备。
该步骤S608的实现过程可以参见步骤S508，在此省略详细描述。
在本实施例中，以终端在无线接入网络内跨接入网设备之间的切换为例进行了说明，而在终端在无线接入网络之间进行切换的情况下，源侧接入网设备发送的切换请求消息中可只携带需要接入网设备建立无线资源的QoS信息，目标侧接收到切换请求消息后，对切换请求消息中包含的QoS信息进行接纳判决，若接纳成功或部分接纳成功，则返回切换准备成功的消息，否则，返回切换准备失败的消息。
在本实施例中，源侧接入网设备可根据目标侧接入网设备切换准备成功消息，决定是否发起切换，将终端切换到目标接入网设备，从而可以保证终端的移动性能。目标侧接入网设备在切换过程中根据预授权QoS为终端配置无线资源，终端切换到目标侧接入网设备后，终端的数据达到时，可以直接在配置好的无线资源上进行数据的发送，从而提高了数据发送的启动速度，提高了用户体验。
参见图7，其示出了本发明实施例提供的另一种通信方法，该方法采用图1所示的系统实现。在图7所示实施例中，该方法包括：
S701：核心网控制面设备发送第一预授权QoS信息给终端，并发送第二预授权QoS信息给接入网设备。
具体实现过程参见S501，在此省略详细描述。
S702：终端发起业务时，发送QoS请求信息给接入网设备。
具体的，终端可以通过控制面信令方式，例如通过SRB消息的方式发送QoS请求信息到接入网设备，或者，终端还可以通过用户面的方式发送QoS请求信息到接入网设备。
其中，当终端通过用户面的方式发送QoS请求信息到接入网设备时，可以采用媒体接入控制层控制元素(英文：Mediu Accece Control-Control Element，简称：MAC-CE)的形式，或者，将上行数据包在默认承载上发送，并且在数据包头中携带新数据指示信息，该新数据指示信息用于指示这是一个新的数据包，并指示该数据包组的QoS信息。所述数据包组的QoS信息可以是一个QoS参数的标识。
进一步地，新数据指示信息可以采用如下方式设置：在PDCP层的数据包头中设置1bit，用来指示是否是新数据，例如该bit的值设置为1时，表示是是新数据，设置为0时，表示不是新数据。
所述新的数据包的含义为该数据包组，接入网设备没有为其配置对应的RB。相应地，接入网设备收到该新的数据包后，为该数据包组配置RB。
具体地，QoS请求信息可以包括请求发送的数据包组在第一预授权QoS信息中对应的QoS信息中的部分内容或全部内容，例如，若终端接收的第一预授权QoS信息中对应的QoS信息中不包含QoS参数，则QoS请求信息中只包括数据包组的标识，否则，可以包括数据 包组的标识及对应的QoS参数，或者只包含数据包组对应的QoS参数。或者，QoS请求信息可以包括反射特性信息，反射特性信息可以包括用于表示能够根据业务的下行QoS参数获得上行QoS参数的指示信息和业务的下行QoS参数。可选地，该反射特性信息还可以包括：上行业务的RB配置。进一步可选地，该反射特性信息还可以包括：业务的slice标识信息，所述slice标识信息包含下述多项中的至少一项：slice id、slice type、租户类型、租户标识、网络功能标识等。
可选地，QoS请求信息还可以包括用于指示QoS信息的获取类型的指示信息，获取类型可以是从第一预授权QoS信息获取(例如，通过包过滤器映射得到QoS参数)，或者可以是根据下行的QoS信息获得的QoS信息。
其中，根据下行的QoS信息获得的上行QoS信息可以包括上行QoS参数和对应的包过滤器，上行QoS信息可以根据下行数据包的信息得到，例如，终端通过将下行数据包包头的IP 5元组进行反转，即将目标地址和源地址进行调换，从而得到上行数据包组的包过滤器，包过滤器对应的上行QoS参数和下行的QoS参数相同，或者，包过滤器对应的上行QoS参数和下行的QoS参数也可以满足其他的映射规则，该映射规则可以由核心网控制面设备预先通知给终端的。
进一步地，当该指示信息指示QoS的获取类型为根据下行的QoS信息获得时，QoS请求信息中还可以包括上行QoS信息对应的下行数据包组的QoS信息或下行数据包组的标识。下行数据包组的标识可以是下行数据包组对应的承载标识、业务标识、流标识、通道标识、无线承载标识等其中之一。
可选地，QoS请求信息还可以包括数据包组的PDU会话信息。PDU会话信息可以包括以下多项中至少一项：接入点名称(英文：Access Point Name，简称：APN)；PDN GW的标识；PDN GW的地址(IP地址，non IP地址)；PDN GW为终端分配的I P地址；会话的标识；DN的标识。
可选地，QoS请求信息还可以包括slice的标识信息，接入网设备将收到的数据包组的slice的标识信息作为数据包组的无线资源配置的参考信息，例如，可为属于不同slice的数据包组配置独立的无线承载。
需要说明的是，若在终端发起业务之前，接入网设备已经为终端的业务配置好了无线承载，例如，根据第二预授权QoS预先建立了无线承载，或者，在配置下行无线承载的同时配置好了上行无线承载，则无需执行步骤S702～S706，直接执行步骤S707。
相应地，接入网设备接收QoS信息。
S703：接入网设备从核心网控制面设备获取QoS策略信息。
该QoS策略信息包括预授权QoS信息，进一步的，在支持反射QoS场景下，该QoS策略信息还包括反射QoS的规则，反射QoS的规则用于指示根据下行QoS信息获得上行QoS信息的方式。所述反射QoS的规则可以是核心网控制面设备通知到接入网设备和终端的，例如，在PDU会换建立过程中通知到接入网设备和终端。或者在UE初始上下文建立过程，或者其它UE和核心网控制面设备之间信令交互的过程。需要说明的是，该步骤S703与步骤S701、S702没有先后顺序，接入网设备可以在接收到QoS请求信息之后获取QoS策略信息，也可以预先获取QoS策略信息。
具体地，在支持反射QoS场景下，该方法还可以包括：
步骤一：下行业务建立时，核心网控制面设备通知接入网设备业务的下行QoS参数， 并且指示该业务具备反射(英文：reflective)特性。即可以根据业务的下行QoS参数得到业务的上行QoS参数。
进一步地，核心网控制面设备可以采用控制面或用户面的方式通知接入网设备业务的下行QoS参数。
步骤二：接入网设备将业务的反射特性信息发送给终端。
具体地，接入网设备将业务的反射特性信息通知到终端可以采用以下两种方式中的一种：
方式一、通过用户面的方式通知到终端。
例如，在PDCP层的数据包头中携带所述反射特性信息。或者，还可以在其他协议层的头携带，例如RLC层、MAC层的头中携带。
方式二、通过控制面的方式通知到终端。
例如，通过RRC消息发送到终端，在消息中显示指示业务具备reflective特性。或者，还可以采用隐式的方式，通过无线承载的上行配置的方式来指示业务具备反射特性，即若接入网设备在反射特性信息中携带了上行无线承载的配置，则表示该业务具备反射特性。
在本实施例中，终端可以通过两种方式获取QoS信息，即第一预授权QoS信息和根据下行QoS信息获得上行QoS信息，在这种情况下，终端可采用时间先后顺序上后得到方式来获取QoS信息。具体地，若所述终端先接收到所述第一预授权QoS信息后接收到所述反射特性信息，则所述上行QoS信息包括根据下行QoS信息得到的QoS信息，若所述终端先接收到所述反射特性信息后接收到所述第一预授权QoS信息，则所述上行QoS信息包括所述第一预授权QoS信息的至少一部分。
S704：接入网设备根据QoS策略信息对终端上报的QoS信息进行验证。若验证通过，则执行S706；否则，执行S705。
当上行QoS信息采用预授权QoS信息时，QoS验证是指QoS参数和数据包过滤器的对应关系是否正确。当上行QoS信息采用反射QoS时，QoS验证是指所述映射的方式是否符合反射QoS的规则。
S705：接入网设备向终端发送用于指示QoS信息错误的消息。
接入网设备通过该步骤S705通知终端QoS信息错误，不进行无线资源的配置。
S706：接入网设备为数据包组配置无线资源，并将无线资源的配置信息发送给终端。
具体地，接入网设备可以根据QoS请求信息中的上行QoS信息为数据包组配置无线资源。相应地，终端接收无线资源的配置信息。
接入网设备为数据包组配置无线资源的具体实现过程可以参见前述步骤502，在此不再详细描述。
S707：终端发起业务时，根据无线资源的配置信息，将业务的数据通过所属数据包组对应的无线承载发送给接入网设备。
该步骤707的具体实现过程可以参见步骤S507，在此不再赘述。
S708：接入网设备接收终端采用建立的无线承载发送的数据，并将接收到的数据发送给核心网用户面设备。
该步骤S708的具体实现过程可以参见步骤S508，在此不再赘述。
此外，除了步骤S508中接入网设备获取数据包对应的PDU会话信息的方式，还可以 采用以下方式获取数据包对应的PDU会话信息：在QoS请求信息中携带有PDU会话信息，直接从QoS请求信息中获取数据包对应的PDU会话信息。
在本实施例中，通过终端和接入网设备之间的QoS请求和验证，建立QoS对应的数据包组的承载，终端和接入网设备之间之间可快速地建立新业务，与现有业务建立流程相比，可以实现快速的数据发送，减少上行数据的发送时延，提高用户体验。
参见图8，其示出了本发明实施例提供的另一种通信方法，该方法采用图1所示的系统实现。在图8所示实施例中，该方法包括：
S801：业务建立时，核心网控制面设备向接入网设备发送业务的下行QoS参数、上行QoS参数，并且指示该业务具备反射特性。
具备反射特性，是指可以根据业务的下行QoS参数得到业务的上行QoS参数。
S802：接入网设备将业务的反射特性信息发送给终端。
其中，所述反射特性信息包含用于表示能够根据业务的下行服务质量参数获得上行服务质量参数的指示信息、业务的下行QoS参数。
可选地，该反射特性信息还可以包括业务的上行RB配置。
该步骤S802可以采用用户面或控制面的方式将业务的反射特性信息发送给终端。具体实现过程可以参见图7所示实施例的相关描述，在此省略详细描述。
可选地，核心网控制面设备可能会对业务的QoS信息进行更新，并发送给接入网设备，则相应地，本实施例的方法还可以包括：
终端接收接入网设备发送的反射特性更新信息，并根据反射特性更新信息更新本地保存的反射特性信息。
具体地，若业务的反射特性信息是采用用户面的方式发送的，则相应地，业务的反射特性更新信息通过不同的包头携带的指示来更新，例如更新为不具备反射特性。若业务的反射特性信息是采用控制面的方式发送的，则相应地，业务的反射特性更新信息通过通过RRC信令的方式来通知属性的更新，例如更新为不具备反射特性。
S803：终端在发起业务时，根据反射特性信息，发送该业务的数据。
具体地，该步骤S803的具体实现可以参见图7所示实施例的相关内容，在此省略详细描述。
需要说明的是，若核心网控制面设备或接入网设备还向终端通知了该业务的上行QoS信息，在这种情况下，终端中存在两种获取QoS参数的方式，此时，终端可采用时间先后顺序上后得到的方式来获取QoS参数。例如，终端先被通知reflective特性，又收到核心网控制面设备通知的上行QoS信息，则采用核心网控制面设备通知的上行QoS信息来获取QoS参数。
本发明实施例还可以包括业务释放流程。具体地，业务释放过程包括以下两种方式：
方式一(由终端触发业务释放)：
参见图9a，在该方式一中，本实施例的通信方法还包括：
步骤S901a：终端监测所述业务是否终止。
具体地，该步骤S901a可以包括：
终端监测是否收到应用层的业务结束指令，当收到业务结束指令时，表示业务终止； 或者，
当所述业务的数据量为零或低于设定门限时，终端启动定时器，若定时器超时时，所述业务的数据量未增加，则表示所述业务终止；若定时器超时之前，业务的数据量增加，则重置定时器，在下一次业务的数据量为零或低于设定门限时，重新启动定时器。
该定时器可以是核心网控制面设备设置的，携带在所述第一预授权QoS信息中发送给所述终端(例如通过NAS消息发送给终端)；或者，所述定时器可以是由所述接入网设备设置的，所述定时器通过RRC消息或用户面控制PDU发送给所述终端的。
实现时，可以为不同业务配置不同的定时器值，并且定时器可以是同时针对上下行的业务，或者单针对上行或下行业务。
此外，设定门限可以采用定时器相同的配置方式，在此省略详细描述。
步骤S902a：当终端监测到业务终止时，向接入网设备发送业务终止请求。
该业务终止请求可以采用控制面或用户面的方式发送。其中，控制面的方式可以是通过RRC消息的方式，该RRC消息中包括需要终止的数据包组的QoS信息和请求业务终止的指示信息，QoS信息是QoS参数的标识。用户面的方式可以是通过指示业务结束的数据包的方式。例如，在PDCP层生成PDCP PDU，将其设置为endmarker PDU，表示该业务的结束；或者，在该PDCP PDU中携带QoS参数的标识和业务终止指示信息，或者采用PDCP PDU本身格式指示业务终止。
另外，还可以通过RLC PDU或MAC PDU的方式来通知接入网设备，其中，所述RLC PDU或MAC PDU中携带QoS参数的标识和业务终止指示信息，或者采用PDU本身格式指示业务终止。
另一种实现方式是：只有终端的对应某一无线承载的所有业务都终止，终端发送RB释放请求消息到接入网设备，在该消息中RB的标识，还携带RB释放请求的原因值，例如是业务结束或所有业务都结束。终端不对单个业务的终止向接入网设备发送业务终止请求，而是只发起无线承载释放请求。
终端还可以通过用户面的方式来通知接入网设备，可以是通过指示业务结束的数据包的方式。例如，在PDCP层生成PDCP PDU，将其设置为endmarker PDU，表示业务的结束，或者，在该PDU中携带所有QoS参数的标识和业务终止指示信息，或者采用PDU本身格式指示业务终止。还可以所述PDU中携带RB的标识。进一步的，所述PDU中不携带QoS参数标识，来表示该RB承载的所有业务终止。
步骤S903a：接入网设备接收该业务终止请求，根据该业务终止请求释放业务的无线资源配置，并向终端发送业务的无线资源配置的释放指示。
接入网设备收到业务请求后，终止为该业务的据包组的无线资源配置，接入网设备向终端发起数据包组的无线资源配置的释放，可通过RRC消息，或者用户面PDU的方式通知终端。
步骤S904a：终端根据接入网设备发送的无线资源配置的释放指示，释放业务的无线资源的配置。
该释放指示可以包括释放无线资源的数据包组的标识或QoS参数的标识。
具体地，该步骤S904a可以包括：
终端释放该数据包组和无线承载的对应关系。
其中，若该数据包组是无线承载的最后一个数据包组，则无线资源配置的释放包含无 线承载的释放。终端收到该释放指示，释放该无线承载。释放指示包含释放无线承载的标识。
进一步的，接入网设备可以不通知终端释放该数据包组和无线承载的对应关系，只通知终端释放无线承载。
其中，若无线承载是该终端的最后一个无线承载，该释放指示可以是RRC链接释放消息。终端收到该释放指示，释放RRC链接。
方式二(由接入网设备触发业务释放)：
参见图9b，在该方式二中，本实施例的通信方法还包括：
步骤S901b：接入网设备监测所述业务是否终止。
具体地，接入网设备通过定时器的方式确定某一业务(可以是上行业务或下行业务)的终止。当所述业务的数据量为零或低于设定门限时，接入网设备启动定时器，若定时器超时时，所述业务的数据量未增加，则表示所述业务终止；若定时器超时之前，业务的数据量增加，则重置定时器，在下一次业务的数据量为零或低于设定门限时，重新启动定时器。
定时器的设置可以采用以下两种方式中的一种：
方式一：核心网控制面设备设置定时器，包含在预授权QoS信息中，由核心网控制面设备通知到接入网设备。当然，也可以将定时器包含在其他消息中发送给接入网设备。
方式二：接入网设备自行设置。
所述触发定时器启动的门限值可由核心网控制面设备设置或接入网设备设置。其中，
方法1：核心网控制面设备设置触发定时器启动的门限值，包含在预授权QoS信息中或者其它消息中，由核心网控制面设备通知到接入网设备。
方法2：接入网设备自行设置触发定时器启动的门限值。接入网设备通过定时器的方式确定某一业务的终止。
步骤S902b：接入网设备释放业务的无线资源配置，并向终端发送业务的无线资源配置的释放指示。
具体过程参见步骤S903a，在此省略详细描述。
步骤S903b：终端接收业务的无线资源的释放指示，根据接入网设备发送的无线资源配置的释放指示，释放业务的无线资源的配置。
具体过程参见步骤S904a，在此省略详细描述。
进一步的，接入网设备可以不通知终端释放该数据包组和无线承载的对应关系，只通知终端释放无线承载。
进一步的，若无线承载是该终端的最后一个无线承载，该释放指示可以是RRC链接释放消息。
通过所述实施方式，接入网设备和/或终端通过定时器方式检测业务的终止，并释放为该业务配置的无线资源。与现有通过信令方式通知业务释放相比，节省了业务终止通知消息的开销，并及时释放无线资源，提高了无线资源的利用率，提升了网络容量。
需要说明的是，图9a和图9b所示的业务释放流程可以与图5、图6、图7和图8所示实施例结合。
参见图10，其示出了本发明实施例提供的另一种通信方法，该方法采用图1所示的系统实现。在图10所示实施例中，通过在NAS PDU中携带用户数据来实现上行业务的快速启动，该方法包括：
S1001：终端向接入网设备发送AS消息。
该AS消息中携带NAS PDU，该NAS PDU包括用户数据。
该AS消息可以为RRC消息，RRC消息包括RRC Connection Request、RRC Connection Reestablishment Request、UE Information Response消息等其中之一。
进一步的，在NAS PDU中包含会话信息，接入网设备根据会话信息将NAS PDU转发到目标核心网控制面设备。
S1002：接入网设备接收AS消息，并将NAS PDU转发到核心网控制面设备。
通过S1001和S1002，可以实现将用户数据携带在NAS PDU中发送给核心网控制面设备。
S1003：核心网控制面设备对该NAS PDU中的用户数据进行检测，并确定该用户数据对应的QoS信息。
具体得，可以结合策略信息，确定用户数据对应的QoS信息。
QoS信息的内容可以与前述步骤S501中的第二预授权QoS信息的内容相同，在此省略详细描述。
S1004：核心网控制面设备将该QoS信息通知到核心网用户面设备、接入网设备和终端。
可选地，该方法还包括核心网控制面设备将该QoS信息通知到终端，通知到终端可以是QoS信息中的部分，例如，可只包括包过滤器、最大速率参数。
S1005：核心网控制面设备从NAS层PDU中得到用户数据，将用户数据发送到应用服务器。
在一种实现方式中，该S1005可以包括：核心网控制面直接将用户数据转发到应用服务器。在该实现方式中，核心网控制面设备可为该终端建立一个核心网控制面设备到应用服务器之间的数据通道，此数据通道可以是IP tunnel的形式。核心网控制面设备可在终端附着过程中为终端建立数据通道，并一直保存，直到终端去附着时释放。
在另一种实现方式中，该S1005可以包括：核心网控制面设备将用户数据发送到核心网用户面设备，核心网用户面设备将用户数据发送到应用服务器。其中，核心网用户面设备和应用服务器之间建立数据通道，核心网控制面设备可在终端附着流程中为终端建立该数据通道，并一直保存，直到终端去附着时释放。
S1006：接入网设备接收到核心网控制面设备发送的QoS信息，根据接收到的QoS信息为该业务配置无线资源。
S1007：接入网设备将无线资源配置信息发送给终端。
该步骤S1006和S1007的具体实现过程可以参见前述步骤S502，在此省略详细描述。
S1008：终端收到接入网设备发送的无线资源配置信息，根据无线资源配置信息发送数据。
具体过程可以参见图5所示实施例的相关描述，在此省略详细描述。
进一步的，在无线资源的配置信息中还可以指示哪一个无线承载是默认无线承载。默认无线承载可以每个session建立一个，用于承载default QoS的业务。
在本实施例中，终端通过NAS发送业务的初始数据，发送到准确的核心网控制面设备，可以提高上行数据的发送速度，加快业务启动，提高用户体验。
参见图11，其示出了本发明实施例提供的另一种通信方法，该方法采用图1所示的系统实现。在图11所示实施例中，通过采用通用承载发送未定义的该方法包括：
S1101：在PDN连接过程中，核心网控制面设备与接入网设备交互，以在核心网用户面设备和接入网设备之间建立通用承载。
其中，通用承载是指一个用户面的数据通道，用于在接入网设备和核心网用户面设备之间的数据包传输，具体的，通用承载是一个除了默认承载对应的接入网设备和核心网用户面设备之间的数据通道以外的数据通道，用于传输未配置QoS的业务数据，例如终端上行业务触发的新数据可先发送到核心网用户面设备，后续再配置QoS信息，那么这些先发送到核心网用户面设备的数据，即为未配置QoS的业务数据。
实现时，通用承载可以是按照PDU会话建立的，即每个会话唯一对应一个通用承载。通用承载也可以是按照节点建立的，即接入网设备和接入网用户面设备之间唯一对应一个通用承载。
默认承载适用于non GBR业务，新的业务建立时，若默认承载不能够承载该业务，则需要为该业务建立一个新的专用承载。在建立新的专用承载之前，新的业务的数据通过通用承载发送。
步骤S1102：终端有新业务的用户数据发送时，终端发送新业务的用户数据到接入网设备。
其中，新业务是指未配置QoS参数的业务。
具体地，终端发送新业务的用户数据到接入网设备可以采用以下方式中的任一种：
第一种、通过SRB来进行上行新业务用户数据的发送，例如，通过SRB1或者SRB2或者是新的SRB。
具体的，终端可以在RRC连接建立完成后，通过SRB来发送新的用户数据。例如可新定义一个消息1，在消息1中专门发送新业务的未配置QoS的用户数据。进一步的，在消息1中还包含该用户数据的会话信息，所述会话信息可以包含以下多项中至少一项：APN；PDN GW的标识；PDN GW的地址(IP地址，non IP地址)；PDN GW为终端分配的IP地址；会话的标识；DN的标识。进一步的，新定义的消息1还包括新数据指示信息，用于指示该数据包是新的数据包，即未配置QoS参数的数据包，具体的，该新数据指示信息可以通过消息名称或消息内容携带。
第二种、接入网设备为每个终端建立一个专门用于传输未配置QoS的用户数据的数据无线承载，终端将所有的未配置QoS的用户数据包都在此数据无线承载上传输，其中，在空口数据包头中携带会话信息。具体的，可以在空口数据包的IP头的空余字段中携带会话信息，或者，在数据包IP层外再添加一个协议头，在该协议头中携带会话信息。或者，在PDCP协议头中携带会话信息。需要说明的是，若数据无线承载是对应每个会话建立的，即每一会话建立一个DRB，则数据包头中无需携带会话信息。
第三种、接入网设备对应每个会话为终端建立一个DRB，终端将该会话的未配置QoS的新用户数据包在此无线承载上传输，其中，在空口数据包头中携带新数据指示信息。具体的，可以在空口数据包的IP头的空余字段中携带新数据指示信息；或者，在数据包的 IP层外再添加一个协议头，在该协议头中携带新数据指示信息；或者，在PDCP头中携带新数据指示信息，如图12a中黑色部分所示。
步骤S1103：接入网设备接收到终端发送的新业务的数据，通过地面侧通道将接收到的新业务的数据发送给核心网用户面设备。
具体地，对于步骤S1102中终端发送新业务的用户数据到接入网设备的第一种和第三种方式，接入网设备可以根据新数据指示信息得知这是一个未配置QoS参数的业务的数据包。对于S1102中终端发送新业务的用户数据到接入网设备的第二种方式，接入网设备可以根据数据无线承载的属性得知这是一个未配置QoS参数的业务的数据包。
在该步骤S1103中，接入网设备会先将第二种和第三种方式中的新数据指示信息去掉，然后再将数据发送给核心网用户面设备。
在本实施例中，接入网设备可以通过通用承载将新业务的数据发送给核心网用户面设备，该通用承载专用于传输所述未配置QoS参数的业务的数据包。进一步的，可在数据包中携带会话信息，具体的，可以在tunnel的协议头中携带该会话信息，例如若采用GPRS隧道协议用户面(GPRS Tunneling Protocol User Plane，简称：GTPU)隧道，则在GTPU头中携带该会话信息。还可以在应用层IP头，或传输层IP头中携带该会话信息，如图12b中黑色部分所示。
在其他实施例中，接入网设备可以通过隧道将新业务的数据发送给核心网用户面设备，在所述隧道上传输的所述未配置QoS参数的业务的数据包携带有新数据指示信息。具体的，可以在tunnel的协议头中携带该新数据指示信息，例如若采用GTPU隧道，则在GTPU头中携带该新数据指示信息。还可以在应用层IP头，或传输层IP头中携带该新数据指示信息。在这种情况下，无需执行步骤S1101。
进一步的，接入网设备和核心网用户面设备之间的通用承载或隧道可以是每个PDU会话建立一个，接入网设备根据新业务的数据归属的PDU会话，选择该PDU会话对应的通用承载或隧道发送数据。
步骤S1104：核心网用户面设备在通用承载上收到新业务的数据，将该新业务的数据发送到对应的DN。
步骤S1105：核心网用户面设备通知核心网控制面设备新业务的数据。
具体的，由于通用承载专用于发送未配置QoS参数的业务的数据，因此核心网用户设备可以知道该通用承载上传输的数据都是未配置QoS参数的业务的数据，在收到通用承载上传输的数据之后，都会将其发送给核心网控制面设备，从而触发授权QoS过程。
