技术领域Technical Field

本申请涉及无线通信技术领域，尤其涉及一种信息交互方法、装置、设备及存储介质。The present application relates to the field of wireless communication technology, and in particular to an information interaction method, device, equipment and storage medium.

背景技术Background Art

目前，通常是应用调用网络开放功能(NEF，Network open function)的服务，应用功能(AF，Application Function)获得NEF的应用程序接口(API，Application Program Interface)接口之后，去通用的API开放框架(CAPIF，Common API Framework for 3GPP Northbound APIs)注册，从而获得NEF的授权。但是，目前只支持NEF对AF访问的授权，而不支持NEF对UE访问的授权，导致NEF无法向UE提供服务。At present, applications usually call the service of the network open function (NEF). After the application function (AF) obtains the application program interface (API) of NEF, it registers with the Common API Framework for 3GPP Northbound APIs (CAPIF) to obtain the authorization of NEF. However, currently only NEF's authorization to access AF is supported, but not NEF's authorization to access UE, resulting in NEF being unable to provide services to UE.

具体实施方式DETAILED DESCRIPTION

在对本申请实施例的技术方案进行介绍之前，先对相关技术进行说明。Before introducing the technical solutions of the embodiments of the present application, the related technologies are first explained.

考虑到现在的网络中，通常是应用调用NEF的服务，AF获得NEF的API接口之后，去通用的API开放框架(CAPIF，Common API Framework for 3GPP Northbound APIs)注册，从而获得NEF的授权。例如，运营商和第三方通过做SLA的线下协议来授权，将第三方应用的身份证明信息(如app ID)提前通知给NEF，并部署在CAPIF上。当应用需要调用NEF服务时，需要携带这些鉴权信息，才能调用CAPIF的信息。但是，当UE通过AF做HTTP 302重定向调用NEF服务时，应用提供商无法知道UE的身份信息，需要研究CAPIF如何对UE授权，使UE可以调用NEF的服务。Considering that in the current network, applications usually call NEF services. After AF obtains NEF's API interface, it registers with the Common API Framework for 3GPP Northbound APIs (CAPIF) to obtain NEF's authorization. For example, operators and third parties authorize through offline SLA agreements, notify NEF of the third-party application's identity information (such as app ID) in advance, and deploy it on CAPIF. When an application needs to call NEF services, it needs to carry this authentication information to call CAPIF's information. However, when UE calls NEF services through AF's HTTP 302 redirection, the application provider cannot know the UE's identity information, and it is necessary to study how CAPIF authorizes the UE so that the UE can call NEF services.

综上所述，在现有方案中，只支持NEF对AF访问的授权，而不支持NEF对UE访问的授权。为了支持UE调用NEF服务，一方面需要NEF能够判定请求来自UE并做出相应，另一方面需要对UE的身份做鉴权和授权认证。相关技术中，都没有提及这两个方面的内容。In summary, in the existing solution, only NEF supports authorization of AF access, but not NEF authorization of UE access. In order to support UE to call NEF services, on the one hand, NEF needs to be able to determine that the request comes from UE and respond accordingly, and on the other hand, it needs to authenticate the identity of UE and authorize authentication. These two aspects are not mentioned in the relevant technology.

基于此，本申请实施例中，终端通过第一网络功能，访问第二网络功能。Based on this, in an embodiment of the present application, the terminal accesses the second network function through the first network function.

另外，考虑到在边缘部署云服务器的场景中，例如云手机、AR/VR眼镜， 端侧的UE可以直接向云端服务器发起服务请求。此时的AS不是单纯的业务服务器，是一个可以处理UE服务请求的代理服务器。因此，UE可以通过直接访问AS请求调用NEF的服务。在调用NEF服务之后，AS还可以通过NEF下向PCF发送相关信息，以供PCF实现隧道配置等。In addition, considering the scenarios where cloud servers are deployed at the edge, such as cloud phones and AR/VR glasses, The UE on the end side can directly initiate a service request to the cloud server. At this time, the AS is not a simple business server, but a proxy server that can process UE service requests. Therefore, the UE can directly access the AS request to call the NEF service. After calling the NEF service, the AS can also send relevant information to the PCF through the NEF for the PCF to implement tunnel configuration, etc.

基于此，本申请实施例中，第四网络功能接收第五网络功能发送的第五信息。Based on this, in the embodiment of the present application, the fourth network function receives the fifth information sent by the fifth network function.

图8是本申请实施例信息交互方法的具体实现流程示意图，如图8所示，所述方法包括步骤801至步骤802：FIG8 is a schematic diagram of a specific implementation flow of the information interaction method according to an embodiment of the present application. As shown in FIG8 , the method includes steps 801 to 802:

步骤801：第五网络功能(AS/AF)将DNAI 1、DNAI 2、DNAI 3发送给NEF，携带UE ID。Step 801: The fifth network function (AS/AF) sends DNAI 1, DNAI 2, and DNAI 3 to NEF, carrying UE ID.

步骤802：NEF将DNAI 1、DNAI 2和DNAI 3预配置在第四网络功能(PCF)中。Step 802: NEF preconfigures DNAI 1, DNAI 2 and DNAI 3 in the fourth network function (PCF).

图9是本申请实施例信息交互方法的具体实现流程示意图，如图9所示，所述方法包括步骤901：FIG. 9 is a schematic diagram of a specific implementation flow of the information interaction method according to an embodiment of the present application. As shown in FIG. 9 , the method includes step 901:

步骤901：终端(UE)向第五网络功能(AS)发起服务请求。Step 901: The terminal (UE) initiates a service request to the fifth network function (AS).

步骤902：AS请求调用NEF服务。Step 902: AS requests to invoke NEF service.

步骤903：NEF请求PCF进行策略更新，配置PDR。Step 903: NEF requests PCF to update the policy and configure PDR.

这里，执行AF influence：UE接入网络到MEC server，触发了MEC server的激活，直接向云端服务器请求服务，触发服务请求流程UE-AS-AF-NEF-PCF。Here, AF influence is executed: UE accesses the network to the MEC server, triggering the activation of the MEC server, and directly requests services from the cloud server, triggering the service request process UE-AS-AF-NEF-PCF.

PCF发现该服务器是个云端服务器，预配置了DNAI(DNAI 1、DNAI 2、DNAI3)的信息，可以在连接状态下动态的做策略更新，让PCF配置N6-N9-N9的PDR(PDR 3)。PCF discovers that the server is a cloud server with pre-configured DNAI (DNAI 1, DNAI 2, DNAI3) information. It can dynamically update policies while connected, allowing PCF to configure PDR (PDR 3) for N6-N9-N9.

图10a是本申请实施例建立的隧道的示意图，如图10a所示，UE在会话建立过程中，SMF根据PCF下发的策略选择UPF，发现PCF配给SMF的PCC rule有三个DNAI，分别用于核心PSA UPF、UL CL UPF和本地PSA UPF的选择，以及会话建立时的隧道建立。 Figure 10a is a schematic diagram of the tunnel established by an embodiment of the present application.

As shown in Figure 10b, a new tunnel is created between the core PSA UPF and the local PSA UPF without forwarding through the UL CL.

这里，PCF下发策略，给三套PDR定方向，新增N6-N9-N9的PDR(PDR 3)。当建立MEC server-边缘PSA UPF-UL CL UPF-核心PSA UPF-DN的流时，MEC server把自己的IP地址和目的IP地址(DN的IP地址)带在请求中，UPF识别到目的地址也是一个服务器，会触发N6-N9-N9的PDR(PDR 3)的执行。Here, PCF issues policies to set directions for the three sets of PDRs, adding a new PDR (PDR 3) for N6-N9-N9. When establishing the flow of MEC server-edge PSA UPF-UL CL UPF-core PSA UPF-DN, the MEC server includes its own IP address and the destination IP address (the IP address of DN) in the request. UPF recognizes that the destination address is also a server, which triggers the execution of the PDR (PDR 3) for N6-N9-N9.

在PCF给SMF下发隧道配置和数据包转发策略后，SMF根据策略向核心PSA UPF、UL CL UPF和本地PSA UPF分别配置数据包处理指示，实现数据包从DN到云服务器的有服务质量保障的数据传输。After PCF sends tunnel configuration and packet forwarding policy to SMF, SMF configures packet processing instructions to the core PSA UPF, UL CL UPF and local PSA UPF according to the policy, to achieve data transmission with quality of service guaranteed from DN to cloud server.
