数据传送的保障方法及通信设备
相关申请的交叉引用
本申请主张在2019年3月6日在中国提交的中国专利申请No.201910169592.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开实施例涉及无线通信技术领域，尤其涉及一种数据传送的保障方法及通信设备。
背景技术
许多垂直行业都有通信的需求，比如铁路调度、自动化控制等。目前可以通过第五代(5 th Generation,5G)通信技术为垂直行业提供一种非公众网络(Non-Public Network，NPN)(简称为非公网)，满足垂直行业的通信需求。非公众网络往往只在一个区域范围内提供服务，并不是全覆盖。
非公网可能存在多种部署方式，比如1)独立的网络；2)非独立的网络；其中非独立的网络比如a)是运营商通信网络的一部分；b)是运营商通信网络的切片。
一个非公网的签约终端可能同时也签约了公众网络(简称为公网)。一个公网的签约终端可能同时也签约了非公网。终端可以通过非公网访问公网服务(比如公共陆地移动网络(Public Land Mobile Network，PLMN)服务)。终端也可以通过公网访问非公网服务(比如通过PLMN接入非公网(access to selected non-public network services via a PLMN))。
在非公网部署时，一些复杂的网络服务并不会部署；在非公网覆盖下，还希望非公网用户能够接入公网服务。反之，在公网覆盖下，也希望公网用户能够接入非公网。当终端通过非公网接入公网的网络服务时，如何在公网中保障非公网的服务，或者，当终端通过公网接入非公网的网络服务时，如何在非公网中保障公网的服务，是目前亟待解决的技术问题。

下面结合附图介绍本公开的实施例。本公开实施例提供的数据传送的保障方法及通信设备可以应用于无线通信系统中。该无线通信系统可以采用5G系统，或者演进型长期演进(Evolved Long Term Evolution，简称eLTE)系 统，或者后续演进通信系统。
参考图1，为本公开实施例提供的一种无线通信系统的架构示意图。如图1所示，包括终端11、第一网络12，以及第二网络和/或第二网络服务13，其中，第二网络服务可以是第二网络的网元上支持的网络服务，或者是通过第二网络接入的网络服务。终端11可以通过第一网络12接入第二网络服务，也可以通过第二网络接入第二网络服务，也可以通过第一网络接入第二网络后，通过第二网络接入第二网络服务。
图2为图1所示的无线通信系统在一种具体应用场景的架构示意图，该应用场景中，终端(UE)通过与第一网络建立PDU会话通道，接入第一网络与第二网络间的代理网元(如非3GPP互通功能(non-3GPP Inter Working Function，N3IWF))，终端通过与代理网元建立IPsec通道，分别连接第二网络的接入移动管理功能(Access Management Function，AMF)和用户平面功能(User Plane Function，UPF)。图3为一种通过第一网络传送终端与第二网络间的控制信令的传输方式示意图。图4为一种通过第一网络传送终端与第二网络间的控制信令的传输格式示意图。从图3和图4中可以看出，终端与第二网络间的控制信令是通过网络协议安全通道(IPsec tunnel，即IPsec通道)传送的。
但图2这种架构的缺点是，终端与第二网络间的数据细节对第一网络是透明的，无法执行服务质量(Quality of Service，QoS)保障。另外，代理网元与第一网络间无控制面接口，无法向第一网络提供QoS信息。所以无法保障重要业务(如IMS语音业务，紧急业务等)的性能和可靠性。
为了支持终端通过第一网络接入第二网络和/或第二网络的服务，还要解决如下问题：
问题1：一般来说，控制信令是用户面数据传送的基础。但由于图2架构中，第二网络的控制信令和用户面数据映射的都是IPsec通道的数据，目前第一网络无法区分第二网络的控制信令和用户面数据，也无法识别哪些IPsec通道用于传送第二网络的控制信令，哪些IPsec通道用于传送第二网络的用户面数据。
问题2：一种保障QoS的方法将数据映射到不同的QoS流。不同的QoS 流具有不同的QoS参数要求。根据QoS流的QoS参数要求达到保障QoS流中数据的效果。但是第一网络只能看到终端与代理网元间的IPsec通道和IPsec通道对应的IP头中的DSCP(Differentiated Services Code Point，差分服务代码点)。DSCP与第二网络间的QoS映射取决于第二网络的策略，第一网络不知道DSCP与第二网络的QoS信息的映射关系，不清楚真正的QoS信息要求是什么。比如语音的QoS等级要求是5QI＝1，其对应的DSCP并不标准化。另外，DSCP与QoS信息之间可以存在多对多的映射关系。信令IPsec通道的DSCP也不固定。
问题3：终端接入第一网络时，可以接入第一网络的业务、第二网络的业务(如IMS业务)或者其他的应用，为了保障第二网络中的业务的QoS，第一网络需要一些特殊的QoS映射策略。目前终端建立的PDU会话不支持第一网络区分哪些是第二网络的数据，哪些是其他应用的数据。
问题3：第一网络监测数据时，不知道如何监测。比如第一网路不知道N3IWF的IP地址，不知道哪些数据来自N3IWF，需要QoS保障。
