技术领域
本公开涉及无线通信领域,尤其涉及一种网络信息开放方法、装置、相关设备及存储介质。
背景技术
网络信息可以用来指导构建优化的端到端网络、实现更短的传输路径、以及更加便捷的管理。然而,由于网络可能归属于不同的运营商/厂商/提供方,对于应用方而言,通常只能将通信网络看作黑盒,不利于构架最佳的端到端网络以满足用户的需求。比如,对于应用功能(Application Function,AF)自行上报数据网络接入标识符(Data Network Access Identifier,DNAI)的情况,AF通常无法获知网络信息,从而难以进行最佳的DNAI配置。
因此,为了给移动通信网络的用户提供更佳的用户体验,需要构建从通信网络到应用服务都最佳的网络,这就需要进行一定程度的网络信息开放,帮助应用服务进行基于网络信息的网络配置,从而构建最佳的端到端网络。

具体实施方式
下面结合附图及实施例对本公开再作进一步详细的描述。
首先,结合AF自行上报DNAI的示例性应用场景,描述相关技术中因不支持根据需要开放网络信息而存在的问题。
具体地,在将边缘计算部署用于第五代移动通信技术(the 5th Generation,5G)系统的情况下,当设计用于边缘解决方案的最佳部署方案时,为了满足边缘业务严苛的业务质量需求,需要建立最佳的传输路径,此外,也需要考虑应用服务器(Application Server,AS)的更改。比如,如图1所示,在一个数据网络名称(Data Network Name,DNN)下,需要考虑如何确定最佳的DNAI和EAS的映射关系,从而保证最佳的传输路径。再比如,当服务EAS变得拥塞或处于停用状态时,需要使另一EAS可以替换服务EAS以服务于终端(也可以称为用户设备(User Equipment,UE),还可以称为用户),即需要考虑如何处理服务EAS的更改以保持最佳传输路径的建立。
基于此,相关技术中,为了建立最佳传输路径,AF需要部署应用,此时需要AF来提供相应的DNAI,即AF向5G核心网(5GC)自行上报DNAI。
然而,DNAI是5GC信息,在真实网络中,所有DNAI均由网络运营商/厂商/提供方创建并基于离线配置传输到AF/AS。所以在很多情况下,AF无法理解DNAI信息,所以仍然会存在AF不提供DNAI信息(即不提供网络信息,可以仅提供AF ID)导致NEF没有配置合适的DNAI,或者AF改变自身信息(比如AS/AF网络地址或位置发生改变)时NEF难以灵活更新DNAI信息的情况。
从上面的描述可以看出,相关技术中,由于5GC没有根据AF的需要向AF开放网络信息,所以AF无法有效地进行网络配置,比如在请求里面提供最佳的DNAI,从而进行网络配置。
另外,由于网络信息包含网络运营商/厂商/提供方的商业秘密,因此,5GC无法向AF开放全部的网络信息。
基于此,在本公开的各种实施例中,核心网的功能(后续描述中记作第一功能)基于AF或EAS(后续描述中记作第二功能)的相关信息确定网络信息,并开放所述网络信息。由于开放的网络信息是基于AF或EAS的相关信息确定的,因此,第一功能能够基于AF或EAS的相关信息,确定AF或EAS所需的、且网络运营商/厂商/提供方能够向AF或EAS开放的网络信息,从而能够帮助AF或EAS进行基于网络信息的网络配置,以构建最佳的端到端网络;同时,能够避免泄露网络运营商/厂商/提供方无法开放的网络信息。

这里,需要说明的是,由于在实际网络中,位置信息的临近并不一定意味着拓扑的临近,很可能出现位置上最近的DNAI,实际存在路由绕路的情况。因此,根据所述第二功能的地址信息、位置信息、应用信息、对应的用户信息、网络相关信息,并结合所述网络拓扑信息可以帮助确定所述第二功能的最佳网络信息,比如不仅仅局限于业务连续性,而是更有效地帮助所述第二功能进行最佳的DNAI配置,比如配置最佳传输路径,进而能够帮助所述第二功能实现现在及未来的协议数据单元(Protocol Data Unit,PDU)会话的用户面路径的最佳。

下面结合应用实施例对本公开再作进一步详细的描述。
在本应用实施例中,为了解决AF(也可以是EAS)不提供DNAI信息导致NEF没有配置合适的DNAI、或者AF改变自身信息时NEF难以灵活更新 DNAI信息等场景下的AF和DNAI之间的映射(英文可以表达为mapping)问题,基于AF提供的信息(即上述第一信息),在网络侧进行DNAI和AF的灵活映射,从而进一步帮助AF进行UE无感知的用户面重新配置。

实际应用时,步骤601中,针对IP地址更新的情况,更新请求可以携带AF的原IP地址、新IP地址以及分配的DNAI;删除请求可以携带原IP地址 和分配的DNAI。
步骤602中,NEF/PCF收到请求后,可以向UDR发送DNAI映射的更新/删除请求,UDR进行相应存储内容的更新/删除,并向NEF/PCF返回更新/删除结果(即上述UDR向第一功能返回的响应)。
本应用实施例提供的方案,一方面,可以通过NEF/PCF开放“基于AS的DNAI映射”服务,实现5GC结合AF相关信息以及网络拓扑信息进行最佳的DNAI配置的能力。另一方面,SMF可以提供“DNAI映射”的服务,从而提供最佳DNAI的配置建议。第三方面,SMF可以提供“DNAI信息查询”的服务,从而能够提供DNAI相关的网络拓扑信息。
综上所述,在本应用实施例中,网络侧能够基于AF提供的信息进行DNAI和AF的灵活映射,并向AF提供保证最佳传输路径的DNAI信息,该DNAI信息可以用于后续PDU会话的建立,从而能够进一步帮助AF进行UE无感知的用户面重新配置;或者,在业务连续性保障中,通过该DNAI信息可以保证最佳传输路径建立,从而保证业务服务质量。
