本申请是以CN申请号为202210351599.8，申请日为2022年4月2日的申请为基础，并主张其优先权，该CN申请的公开内容在此作为整体引入本申请中。
技术领域
本公开涉及通信技术领域，尤其涉及一种支持服务化接口的短消息传输方法、网元、设备及介质。
背景技术
随着网络和终端的不断升级，提供短消息转发的SMS(Short Message Service，短消息服务)网元也在不断变化。图1示出了短消息服务SMS的演进过程，SMS-SC作为短消息存储和转发的短消息服务中心，是2G网络时代便存在的网元，该网元基于MAP(Mobile Application Part，移动应用部分)协议与周边网元进行交互，在各大运营商网络中占据较大的数量。4G网络的网元，主要基于SIP协议进行交互，新增实现SIP协议与MAP协议之间编解码转换的IPSMGW(IP Short Message Gateway，短消息网关)网元，可避免SMS-SC(Short Message Service Center，短消息中心)升级改造带来的成本影响。5G网络的网元，主要基于HTTP2协议进行交互，3GPP在5G核心网中新增实现HTTP2协议与MAP协议之间编解码转换的SMSF(Short Message Service Function，短消息服务功能)网元，来避免SMS-SC升级改造带来的成本影响。
SMSF网元作为5G核心网的短消息服务网元，可为5G终端用户提供注册、注销、收发NAS(Non-Access Stratum，非接入层)短消息服务。在3GPP 5G标准R17版本之前，SMSF网元和SMS-GMSC网元(SMS-SC的入口交换机)之间采用传统MAP/Diameter协议接口进行短消息传输。而在3GPP 5G标准R17版本中，SMSF网元和SMS-GMSC网元之间采用服务化接口进行短消息传输。

此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
在相关技术中的短消息传输系统中，一部分SMSF网元支持服务化接口，而另一部分遗留的SMSF网元不支持服务化接口，可能导致其他网元不知道与其通信的SMSF网元是否支持服务化接口，从而引发遗留SMSF的兼容性问题。
鉴于此，本公开提供一种支持服务化接口的短消息传输方法，至少在一定程度上克服相关技术中短消息传输系统无法识别SMSF网元是否支持服务化接口的问题。
为便于理解，在介绍本公开实施例之前，首先对本公开实施例中涉及到的几个名词进行解释如下：
UE：User Equipment，用户设备，也称用户终端。
SMS：Short Message Service，短消息服务，一种通过短消息(也称短消息)业务，最长可发送160个字符。
SMSF：Short Message Service Function，短消息服务功能。
SMS-SC：Short Message Service Center，短消息服务中心，是一个独立于无线网络的业务处理系统。短消息不是直接由发送方到达接收方，而是由短消息中心SMS- SC转发的。
SMS-GMSC：Gateway MSC for Short Message Service，短消息服务网关移动交换中心，是SMS-SC的入口交换机，SMS-SC与移动用户UE通信时，通过SMS-GMSC接入移动用户UE。
AMF：Access and Mobility Mangement Function，接入和移动性管理功能网元。
UDM：Unified Data Management，统一数据管理功能。
NAS：Non-Access Stratum，非接入层。
SBI：Service Based Interface，服务化接口。
IPSMGW：IP Short Message Gateway，短消息网关。
下面结合附图，对本公开实施例的具体实施方式进行详细说明。
图2示出本公开实施例中一种应用系统架构示意图。图2示出了可以应用本公开实施例中支持服务化接口的短消息传输方法的示例性应用系统架构示意图。在一些实施例中，该应用架构还可以应用于物联网中短消息的传输。
如图2所示，该应用系统架构包括：SMSF网元10、UDM网元20、SMS-GMSC网元30、SMS-SC网元40、AMF网元50和用户终端60。
其中，SMSF网元10是5G核心网中的短消息服务网元，通过N20接口与5G核心网中的AMF网元50交互，通过N21接口与UDM网元交互，通过MAP接口协议与SMS-SC网元、IPSMGW网元对接，为用户终端60提供注册、注销、收发NAS短消息服务。
需要说明的时，本公开实施例中的用户终端60可通过有线网络或无线网络接入AMF网元50。在一些实施例中，当用户终端60通过无线网络接入AMF网元50时，用户终端60可通过5G及以后版本的基站(例如：5G NR NB)，或者其他通信系统中的基站(例如：eNB基站)等网络侧设备接入AMF网元50。
当用户终端60开关机、位置移动、网络切换(例如，4G网络/5G网络的切换)时，会触发终端注册/注销的流程，经由AMF网元50到达SMSF网元。SMSF网元在终端注册流程中，会记录该用户终端60所在的AMF网元50；当接收到来自SMS-SC网元中呼到该用户终端60的短消息时，SMSF网元可正确转发给该用户终端60所在的就近AMF网元。在终端注册流程中，SMSF网元还会将自身注册到UDM网元，告知UDM网元该用户终端60在本SMSF网元，并从UDM网元获取和订阅该用户终端60的签约信息，用于在该用户终端60后续收发NAS短消息时，由SMSF网元对 其鉴权。
如本申请背景技术部分介绍的，在引入服务化接口传输短消息的短消息传输系统中，一部分SMSF网元支持服务化接口，而另一部分遗留的SMSF网元不支持服务化接口，为了实现短消息的正确传输，需要识别短消息传输系统中哪些SMSF网元支持服务化接口，哪些SMSF网元不支持服务化接口，以便选择相应的接口协议进行短消息传输。
可选地，上述的无线网络或有线网络使用标准通信技术和/或协议。网络通常为因特网、但也可以是任何网络，包括但不限于局域网(Local Area Network，LAN)、城域网(Metropolitan Area Network，MAN)、广域网(Wide Area Network，WAN)、移动、有线或者无线网络、专用网络或者虚拟专用网络的任何组合)。在一些实施例中，使用包括超文本标记语言(Hyper Text Mark-up Language，HTML)、可扩展标记语言(Extensible MarkupLanguage，XML)等的技术和/或格式来代表通过网络交换的数据。此外还可以使用诸如安全套接字层(Secure Socket Layer，SSL)、传输层安全(Transport Layer Security，TLS)、虚拟专用网络(Virtual Private Network，VPN)、网际协议安全(Internet ProtocolSecurity，IPsec)等常规加密技术来加密所有或者一些链路。在另一些实施例中，还可以使用定制和/或专用数据通信技术取代或者补充上述数据通信技术。
用户终端60可以是各种电子设备，包括但不限于智能手机、平板电脑、膝上型便携计算机、台式计算机、可穿戴设备、增强现实设备、虚拟现实设备等。
可选地，不同的用户终端60中安装的应用程序的客户端是相同的，或基于不同操作系统的同一类型应用程序的客户端。基于终端平台的不同，该应用程序的客户端的具体形态也可以不同，比如，该应用程序客户端可以是手机客户端、PC客户端等。
本领域技术人员可以知晓，图2中SMSF网元10、UDM网元20、SMS-GMSC网元30、SMS-SC网元40、AMF网元50和用户终端60的数量仅仅是示意性的，根据实际需要，可以具有任意数目的网元和终端。本公开实施例对此不作限定。
在上述图2所示的系统架构下，本公开实施例中提供的支持服务化接口的短消息传输系统中，通过在SMSF网元的相关信息中增加SMSF网元是否支持服务化接口SBI的标识信息(SBI-support indication，即SBI-support标识，也可以称为SBI-support指示)，能够利用该标识信息，识别短消息传输系统中用于传输短消息的SMSF网元是否支持服务化接口SBI，进而确定是否选择支持服务化接口的协议传输短消息，使得支持服务化接口的短消息传输系统能够兼容支持服务接口的SMSF网元和不支持服 务化接口SBI的SMSF网元。
在具体实施时，主要包括如下流程：①SMSF网元向UDM网元注册携带SBI-support标识的用户上下文信息；②SMS-GMSC网元从UDM网元获取携带SBI-support标识的短消息路由信息；③SMS-GMSC网元根据携带的SBI-support标识，选择相应的协议传输短消息。
本公开实施例中提供了一种支持服务化接口的短消息传输方法，该方法可以应用但不限于图2所示的系统架构。
图3示出本公开实施例中一种支持服务化接口的短消息传输方法流程图。如图3所示，本公开实施例中提供的支持服务化接口的短消息传输方法包括如下步骤S302至S306。
在步骤S302，SMSF网元向UDM网元发送携带SBI-support标识的用户上下文注册信息，其中，SBI-support标识用于标识SMSF网元是否支持服务化接口SBI。
在步骤S304，UDM网元向SMS-GMSC网元返回携带SBI-support标识的短消息路由信息。
在步骤S306，SMS-GMSC网元根据UDM网元返回的携带SBI-support标识的短消息路由信息，确定是否采用服务化接口传输短消息。
需要说明的是，本公开实施例中用于标识SMSF网元是否支持服务化接口SBI的SBI-support标识可以使用任意数字，也可以使用逻辑值0或1标识SMSF网元是否支持服务化接口SBI，本公开对SBI-support标识的具体形式不作限定，只要是能够标识SMSF网元是否支持服务化接口SBI的信息均在本公开的保护范围内。
当SMSF网元创建用户上下文注册信息后，要向UDM网元注册自身的地址信息，SMSF网元向UDM网元发送携带SBI-support标识的注册信息后，UDM中与SMSF网元相关的信息都可以携带SBI-support标识。
例如，可以在“UE content in SMSF data”这个数据中新增SBI-support标识，使得UDM存储SMSF网元是否支持服务化接口SBI的信息。在一些实施例中，“UE content in SMSF data”中的信息包括但不限于：SMSF网元的地址、SMSF网元的SBI-support标识、SMSF网元的接入方式(3GPP或非3GPP接入)。
当SMSF网元创建UE上下文信息并完成在UDM网元的注册后，SMS-GMSC网元接收到主叫终端向被叫终端发送的短消息(也称短信)后，会去UDM网元查询将短消息传输到被叫终端的路由信息，当UDM网元返回路由信息时，将SMSF网元是 否支持服务化接口SBI的标识信息一起返回给SMS-GMSC网元，可使得SMS-GMSC网元根据从UDM网元获得的路由信息，去相应的SMSF网元调取短信传输服务。
至此，提供了根据本公开一些实施例的支持服务化接口的短消息传输方法。在该方法中，由短消息服务功能SMSF网元向统一数据管理功能UDM网元发送携带SBI-support标识的用户上下文注册信息，使得UDM网元向短消息服务网关移动交换中心SMS-GMSC网元返回携带SBI-support标识的短消息路由信息，以便SMS-GMSC网元根据UDM网元返回的携带SBI-support标识的短消息路由信息确定是否采用服务化接口传输短消息。通过本公开实施例，能够识别短信传输系统中的SMSF网元是否支持服务化接口，进而确定是否采用服务化接口传输短消息。
