技术领域
本申请涉及通信技术领域，尤其涉及一种数据处理方法和数据处理装置。
背景技术
车到万物(vehicle-to-everything，V2X)无线通信技术是将车辆与一切事物相连接的新一代信息通信技术，其中，V代表车辆，X代表任何与车交互信息的对象，例如，车、人、交通路侧基础设施和网络等。V2X无线通信技术采用了两种通信接口：一种是车、人、路之间的直接通信接口，例如，邻近通信5(prose communication 5，PC5)接口，可用于车、人、路之间的短距离通信；另一种是终端和基站之间的通信接口，例如，通用陆地无线接入网(universal terrestrial radio access network，UTRAN)与用户设备直接的无线接口(the radio interface between UTRAN and the user equipment，Uu)接口，可实现长距离和更大范围的可靠通信。
目前，在基于5G通信技术的V2X无线通信系统中，策略控制功能(policy control function，PCF)实体向接入网设备发送用于PC5接口通信的服务质量(quality of service，QoS)参数，该QoS参数可以用于多个(两个或两个以上)终端设备之间进行PC5接口通信。具体过程为：当终端设备请求与网络建立连接时，接入和移动性管理功能(access and mobility management function，AMF)实体与PCF实体为该终端设备建立N11接口连接，AMF实体向PCF实体请求该QoS参数，然后，PCF实体通过该N11接口连接向AMF实体发送该QoS参数，AMF实体向接入网设备发送该QoS参数。
上述方案中终端设备请求与网络建立连接包括多种场景，例如，终端设备处于空闲态且再次请求与网络建立连接，或者该终端设备处于连接态且请求从源接入网设备切换至目标接入网设备等等。由于该多种场景下均执行上述动作，导致操作流程繁杂，信令开销较大。

具体实施方式
本申请实施例提供了一种数据处理方法和数据处理装置，用于简化AMF实体向该终端设备请求连接的接入网设备或切换的目标接入网设备下发QoS参数的操作流程，减少信令 开销。

UPF实体：作为协议数据单元(protocol data unit，PDU)会话连接的锚定点，负责对用户设备的数据报文过滤、数据传输/转发、速率控制、生成计费信息等。
下面再通过图1B介绍本申请实施例的一个系统架构图。

需要说明的是，本申请实施例的数据处理方法可以应用于图1A或图1B所示的通信网 络，也可以应用于3G，或4G通信网络，还可以应用于未来通信网络，例如，6G网络、7G网络等，且上述涉及的网元名称不限定，均可以替换成在未来通信网络中具备相同或相似功能的网元名称，本申请不做限定。
请参阅图2，图2为本申请实施例提供的一种数据处理方法的示意图。如图2所示，该方法包括如下步骤：
201、AMF实体接收用于终端设备进行PC5接口通信的QoS参数。
其中，该QoS参数用于该终端设备进行PC5接口通信。
PC5接口通信可以是指多个(两个或者两个以上)终端设备之间通过PC5接口进行的通信。
具体地，AMF实体可以通过如下方式接收该QoS参数：
方式一：AMF实体接收来自PCF实体的该QoS参数。
其中，该PCF实体可以为用于V2X通信的PCF实体。上述方法还可以包括：该AMF实体根据该终端设备的签约信息，为该终端设备选择用于V2X通信的PCF实体。
方式二：AMF实体接收来自接入网设备的该QoS参数。
其中，该接入网设备可以为该终端设备当前所连接的接入网设备，或者在为该终端设备当前所连接的接入网设备之前为该终端设备提供服务的接入网设备。
202、AMF实体保存QoS参数。
示例性地，AMF实体通过N2接口接收该QoS参数，然后该AMF实体直接保存该QoS参数；或者，该AMF实体接收N2接口信息，且该N2接口信息包括QoS参数，该AMF实体保存该N2接口信息，本申请不做限定。
203、当满足预设条件时，AMF实体向第一接入网设备发送QoS参数。
其中，该第一接入网设备可以为该终端设备请求连接的接入网设备或者切换的目标接入网设备。该AMF实体可以通过N2接口直接向该第一接入网设备发送该QoS参数，也可以向该第一接入网设备发送N2接口信息，且该N2接口信息包含该QoS参数，具体此处不做限定。
其中，预设条件可以有多种，下面通过举例说明：
1、当该终端设备处于空闲态，且该AMF实体接收来自第一接入网设备的N2接口信令连接建立请求。
其中，该N2接口信令连接建立请求可以用于请求为该终端设备建立N2接口信令连接。
例如，终端设备处于空闲态，终端设备通过RAN设备向AMF实体发送服务请求消息(service request)或注册请求消息(registration request)；一种可能的实现方式中，该服务请求消息或注册请求消息包含在无线资源控制连接建立完成消息(radio resource control setup complete)中，终端设备向RAN设备发送该无线资源控制连接建立完成消息；然后，RAN设备向AMF实体发送终端设备的初始消息(initial message)，该初始消息包含该服务请求消息或注册请求消息。那么，AMF实体向RAN设备发送初始上下文建立请求(initial context setup request)，该上下文建立请求包括用于终端设备进行PC5接口通信的QoS参数。
示例性地，当终端设备请求创建与网络的连接时，AMF实体向该终端设备请求连接的第一接入网设备发送该QoS参数，为了使得AMF实体能够直接向第一接入网设备发送其本地保存的QoS参数，当AMF实体接收到来自第一接入网设备的N2接口信令连接建立请求时，则AMF实体向第一接入网设备发送该QoS参数。
需要说明的是，若该终端设备请求与网络创建连接时，该终端设备所连接的接入网设备仍为该源接入网设备，则源接入网设备和第一接入网设备可以是同一个接入网设备，源接入网设备可以为在终端设备连接该第一接入网设备之前为该终端设备提供服务的接入网设备。即终端设备只是断开了该第一接入网设备的连接，在之后重新建立与该第一接入网设备的连接；若该终端设备请求与网络创建连接时，所连接的接入网设备为第一接入网设备，即终端设备本次所连接的第一接入网设备与该源接入网设备不是同一个接入网设备。具体以终端设备的实际连接情况为基准，本申请对于上述所描述的连接场景都适用，具体不做限定。
