相关申请的交叉引用
本申请基于申请号为201710303812.7、申请日为2017年05月03日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本公开涉及通信技术领域，特别涉及一种信息传输的方法、设备及存储介质。
背景技术
图1示出了5G(5th-Generation，第五代移动通信技术)网络短信下发成功流程，其中，AMF(Access and Mobility Management Function，接入和移动性管理功能)、UDM(Unified Data Management，统一数据管理)、SMSF(SMS Function，短信功能)是5G核心网控制面的NF(Network Function，网络功能实体)。
如图1所示，该流程包括：
步骤101：主叫端UE(用户设备)将短信内容传输至SMSC(Short Message Service Center，短消息服务中心)；
步骤102：SMSC向UDM发送路由查询请求，获取被叫端UE的SMSF地址；
步骤103：SMSC向SMSF发送对应的短信内容；
步骤104：SMSF通过AMF向被叫端UE进行寻呼并请求NAS(Non-Access-Stratum，非接入层)透传隧道；
步骤105：AMF透传SMSF与UE之间的短信及响应、短信报告及响 应；
步骤106：SMSF收到被叫端UE的短信报告后向SMSC返回短信报告，短信下发完成后；
步骤107：SMSF向AMF请求释放NAS透传隧道；
用户不可及的状态标记流程如图2所示，包括：
步骤201：当在短信下发的过程中，主叫端UE将短信内容传输至SMSC；
步骤202：SMSC向UDM发送路由查询请求，获取被叫端UE的SMSF地址；
步骤203：SMSC向SMSF发送对应的短信内容；
步骤204：SMSF通过AMF向被叫端UE进行寻呼并请求NAS透传隧道；
步骤205：SMSF接收不到寻呼响应时，将在SMSF内部针对该用户设备UE设置MNRF(Mobile Station Not Reachable Flag，用户不可及标记)标志；
步骤206：SMSF向SMSC返回MTSMS失败报告；
步骤207：SMSF向AMF订阅用户活动状态；
步骤208：SMSC收到MTSMS(Mobile terminating SMS，终端终止短信)失败报告后向UDM请求设置MNRF标志；
步骤209：UDM收到SMSC的报告后针对该UE设置MNRF以及SMSC地址；
步骤210：UDM向SMSF订阅用户活动状态。
用户状态由不可及变为可及后，用户可及后通知重发流程图如图3所示，步骤301：AMF检测到UE的活动；
步骤302：AMF向SMSF发送用户状态通知；
步骤303：SMSF清除内部的MNRF标志；
步骤304：SMSF向UDM发送用户状态通知；
步骤305：UDM清除内部的MNRF标志；
步骤306：UDM按照对应的SMSC地址发送通知至相应的SMSC。
SMSC收到通知，尝试重新进行该用户的缓存短消息队列的下发流程。
5G网络属于服务化架构，NF之间采用服务化接口，发送通知消息需要提前订阅。所以，为了用户可及后进行通知，在标记用户不可及状态的流程中需要有两个订阅过程。而这两个订阅过程不是独立的，之间是存在耦合关系的，使得整体方案不灵活，占用了较多的资源，耦合方式的订阅过程也使得系统处理效率较差，无法较有效地设置UE的MNRF标志。
综上，现有的短信重发处理方案不灵活，系统处理效率较差，同时无法较有效的设置UE的MNRF标志。

具体实施方式
为了使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开作进一步地详细描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
下面结合说明书附图对本公开实施例作进一步详细描述。
在下面的说明过程中，先从UDM侧和AMF侧的配合实施进行说明，最后分别从UDM侧和AMF侧的实施进行说明，但这并不意味着二者必须配合实施，实际上，当UDM侧和AMF侧分开实施时，也解决了分别在UDM侧和AMF侧所存在的问题。只有两者结合使用时，会获得更好的技术效果。
如图4所示，本公开实施例信息传输的系统，该系统包括UDM 40和 AMF 41；
UDM 40，配置为向AMF 41订阅终端的用户状态的通知，以使所述AMF 41检测所述UDM 40订阅的终端的用户动态；接收AMF 41发送的所述终端的用户状态的通知，根据接收到的所述用户状态的通知设置所述终端的短信无法下发标识，其中所述用户状态的通知是所述AMF 41根据检测的所述终端的用户动态确定的；
AMF 41，配置为检测所述终端的用户动态；根据检测到的终端的用户动态及UDM 40订阅的用户状态的通知向所述UDM 40发送所述终端的用户状态的通知。
这里，UDM 40向AMF 41订阅终端的用户状态的通知，以使所述AMF41检测所述UDM 40订阅的终端的用户动态，以便使所述AMF 41根据检测到的终端的用户动态及UDM 40订阅的用户状态的通知向所述UDM 40发送所述终端的用户状态的通知。
也就是说，所述UDM 40向AMF 41订阅终端的用户状态的通知的目的是：让所述AMF 41根据检测到的终端的用户动态及UDM 40订阅的用户状态的通知向所述UDM 40发送所述终端的用户状态的通知。
其中，用户状态的通知是指UDM 40向AMF 41订阅的一种与终端的状态有关的信息，UDM 40向AMF 41订阅用户状态的通知情况分两种，UDM 40向AMF 41只订阅用户可及通知，UDM 40向AMF 41订阅用户可及通知和用户不可及通知；
下面就这两种情况分别进行介绍：
第一种，UDM 40向AMF 41订阅用户可及通知；
所述UDM 40确定当前终端的用户状态为用户不可及后向AMF 41订阅用户可及通知；
用户状态为用户不可及指终端当前连接不到，信息无法正确发送至该终端，或向终端发送寻呼，没有得到响应。
所述UDM 40确定当前终端的用户状态为用户不可及的方式有许多种，例如当在短信下发的过程中，SMSF接收不到寻呼响应时，向SMSC返回MT失败报告；SMSC收到MT失败报告后向UDM40请求设置MNRF标志。UDM40收到SMSC的报告后针对该终端设置MNRF并记录对应的SMSC地址，以便在用户可及后向对应的SMSC发起通知；当UDM 40确定当前终端存在MNRF标志，则UDM 40确定当前终端的用户状态为用户不可及。
在实施中，能够确定当前终端的用户状态的方式有许多种，凡是可以确定当前用户状态的均适用于本公开实施例。
UDM 40确定当前终端的用户状态为用户不可及后，可以先确定UDM40是否已经向AMF 41订阅了用户可及通知，若未订阅，则UDM 40可以向AMF 41订阅用户可及通知；若已订阅，则可以不向AMF 41订阅用户可及通知；
UDM 40确定当前终端的用户状态为用户不可及后，也可以不确定UDM 40是否已经向AMF 41订阅了用户可及通知，直接向AMF 41订阅用户可及通知。
本公开实施例订阅用户可及通知的流程，如图5所示，包括以下步骤：
步骤501：主叫端UE向SMSC传输短信内容；
步骤502：SMSC向UDM发送路由请求并获取被叫端的SMSF地址；
步骤503：SMSC向SMSF发送短信内容；
步骤504：SMSF通过AMF向被叫端UE进行寻呼，并请求NAS透传隧道；
步骤505：SMSF未接收到寻呼响应；
步骤506：SMSF向SMSC返回MT失败报告；
步骤507：SMSC向UDM发送设置MNRF标志请求；
步骤508：UDM针对该终端设置MNRF标志；
步骤509：UDM向AMF订阅用户可及通知。
UDM 40向AMF 41订阅用户可及通知后，AMF 41与UDM 40之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM 40发送用户可及通知，并针对该终端检测其用户动态。
用户动态是指当前终端是否可以获取传输的信息或发送信息的状态。若可以检测到终端的用户动态，说明当前终端可以获取传输的信息也可以发送信息，若无法检测到终端的用户动态，则说明当前终端无法获取传输的信息也无法发送信息。
其中，检测终端的用户动态的方式有许多种，例如可以向终端发送寻呼，当接收到终端的寻呼响应后确定检测到终端的用户动态，也可以定位终端的位置，根据终端的位置移动来检测终端的用户动态，当定位到终端的位置后确定检测到终端的用户动态，若无法定位终端的位置，则确定无法检测到终端的用户动态。再比如，收到用户终端主动发起的请求，如业务请求、位置更新请求，收到请求后确定检测到终端的用户动态。
当AMF 41确定检测到所述终端的用户动态后向所述UDM 40发送用户可及通知；
由于之前终端的用户状态为不可及，也就是说，AMF 41之前无法连接至终端。
而若在订阅了用户可及通知后，AMF 41检测到终端的用户动态，则向所述UDM 40发送用户可及通知，以表明此时终端可连接；
所述UDM 40接收到所述AMF 41发送的用户可及通知；且所述UDM40针对所述终端已设置短信无法下发标识，则所述UDM 40清除短信无法下发标识。
所述UDM 40接收到所述AMF 41发送的用户可及通知后，可以将之前设置的短信无法下发标识清除，若UDM 40中针对该终端保存了对应的SMSC地址，UDM 40可以向该SMSC发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
UDM40针对终端的短信无法下发标识，可以沿用现有的MNRF标志，也可以设置其他的标志信息表示当前的短信无法下发标识。
本公开实施例订阅用户可及通知后用户状态由不可及变为可及的流程，如图6所示，包括：
步骤601：AMF确定检测到终端的用户动态；
步骤602：AMF向UDM发送用户可及通知；
步骤603：UDM清除MNRF标志；
步骤604：UDM向SMSC发送通知。
UDM 40向AMF 41订阅终端的用户可及通知；AMF 41根据检测到的终端的用户动态向所述UDM 40发送所述终端的用户可及通知；所述UDM40接收AMF 41发送的所述终端的用户可及通知，根据接收到的所述用户可及通知设置所述终端的短信无法下发标识；在信息传输过程中只需一次订阅过程，UDM 40就可以直接从AMF 41获知用户状态，并可以对终端的短信无法下发标识进行清除，此种方式可以解决了服务化架构中业务逻辑复杂、服务间耦合、消息增加使得访问效率低的问题。
第二种，所述UDM 40向所述AMF 41订阅用户可及通知和用户不可及通知。
无论当前终端的用户状态如何，UDM 40可以向所述AMF 41订阅两种用户状态的通知，也即用户可及通知和用户不可及通知；
UDM 40确定当前终端的用户状态为用户不可及后，可以先确定UDM40是否已经向AMF 41订阅了用户可及通知，若未订阅可以向AMF 41订阅用户可及通知；若已订阅，则可以不向AMF 41订阅用户可及通知；
UDM 40确定当前终端的用户状态为用户不可及后，也可以不确定UDM 40是否已经向AMF 41订阅了用户可及通知，直接向AMF 41订阅用户可及通知。
UDM 40确定当前终端的用户状态为用户可及后，可以先确定UDM 40 是否已经向AMF 41订阅了用户不可及通知，若未订阅可以向AMF41订阅用户不可及通知；若已订阅，则可以不向AMF 41订阅用户不可及通知；
UDM 40确定当前终端的用户状态为用户可及后，也可以不确定UDM40是否已经向AMF 41订阅了用户不可及通知，直接向AMF 41订阅用户不可及通知。
UDM 40向AMF 41订阅用户可及通知和用户不可及通知后，AMF 41与UDM 40之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM 40发送用户可及通知或用户不可及通知。
当AMF 41确定检测到所述终端的用户动态后向所述UDM 40发送用户可及通知；
所述AMF 41确定无法检测到所述终端的用户动态后向所述UDM 40发送的用户不可及通知。
若在订阅了用户可及通知后，AMF 41可以连接至终端，检测到终端的用户动态，则向所述UDM 40发送用户可及通知，以表明此时终端可连接；
若所述UDM 40接收到所述AMF 41发送的用户可及通知，且所述UDM 40针对所述终端已设置短信无法下发标识，则所述UDM 40清除短信无法下发标识；
所述UDM 40接收到所述AMF 41发送的用户可及通知后，可以将之前针对所述终端设置的短信无法下发标识清除，若UDM 40中针对该终端保存了对应的SMSC地址，UDM 40可以向该SMSC发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
若在订阅了用户不可及通知后，AMF 41无法连接至终端，无法检测到终端的用户动态，则向所述UDM 40发送用户不可及通知，以表明此时终端不可连接；
若所述UDM 40接收到所述AMF 41发送的用户不可及通知，且所述UDM 40针对所述终端未设置短信无法下发标识，则所述UDM 40针对所 述终端设置短信无法下发标识。
所述UDM 40接收到所述AMF 41发送的用户不可及通知后，可以针对所述终端设置短信无法下发标识，当SMSC需要下发短信并向UDM 40进行查询服务时，UDM 40确定当前终端的用户状态为用户不可及时，返回错误响应，并记录该SMSC地址，以便在用户状态由不可及变为可及后，可以向该SMSC发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
本公开实施例订阅用户通知后用户状态由不可及变为可及的流程，如图7所示，包括：
步骤701：UDM向AMF订阅用户可及通知和用户不可及通知；
步骤702：AMF确定无法检测到用户动态；
步骤703：AMF向UDM发送用户不可及通知；
步骤704：UDM针对该终端设置MNRF标志；
步骤705：主叫端UE向SMSC传输短信内容；
步骤706：SMSC向UDM发送路由查询请求并获取被叫端UE SMSF地址；
步骤707：UDM向SMSC发送获取失败响应；
步骤708：AMF确定检测到终端的用户动态；
步骤709：AMF向UDM发送用户可及通知；
步骤710：UDM清除MNRF标志；
步骤711：UDM向SMSC发送通知。
UDM 40向AMF 41订阅终端的用户可及通知和用户不可及通知；AMF41根据检测到的终端的用户动态向所述UDM 40发送所述终端的用户可及通知或用户不可及通知；所述UDM 40接收AMF 41发送的所述终端的用户可及通知或用户不可及通知，根据接收到的用户可及通知或用户不可及通知设置所述终端的短信无法下发标识；在信息传输过程中只需一次订阅 过程，UDM 40就可以直接从AMF 41获知用户状态，并可以对终端的短信无法下发标识进行清除或者设置，此种方式可以在SMSC向UDM 40查询被叫路由时直接告知SMSC，避免了SMSC向SMSF前转短信、SMSF向UE下发寻呼、SMSF向SMSC返回错误、SMSC请求UDM40进行MNRF置位的过程，减少了对网络资源的占用，简化了信息传输的过程。
基于同一发明构思，本发现实施例还提供了一种信息传输的设备，由于该设备解决问题的原理与本公开实施例信息传输的系统相似，因此该设备的实施可以参见系统的实施，重复之处不再赘述。
如图8所示，本公开实施例提供了一种信息传输的UDM，该UDM包括订阅模块801和第一传输模块802；
订阅模块801，配置为向AMF订阅终端的用户状态的通知；
第一传输模块802，配置为接收AMF发送的所述终端的用户状态的通知，根据接收到的所述用户状态的通知设置所述终端的短信无法下发标识，其中所述用户状态的通知是所述AMF根据检测的所述终端的用户动态确定的。
订阅模块801向AMF订阅用户状态的情况分两种，订阅模块801向AMF只订阅用户可及通知，订阅模块801向AMF订阅用户可及通知和用户不可及通知；
下面就这两种情况分别进行介绍：
第一种，订阅模块801向AMF订阅用户可及通知；
所述订阅模块801确定当前终端的用户状态为用户不可及后向AMF订阅用户可及通知；
用户状态为用户不可及指终端当前连接不到，信息无法正确发送至该终端，或向终端发送寻呼，没有得到响应。
所述订阅模块801确定当前终端的用户状态为用户不可及的方式有许多种，例如当在短信下发的过程中，SMSF接收不到寻呼响应时，将针对该 终端设置MNRF标志；向SMSC返回MT失败报告；SMSC收到MT失败报告后向UDM请求设置MNRF标志。订阅模块801收到SMSC的报告后针对该终端设置MNRF并记录对应的SMSC地址，以便在用户可及后向对应的SMSC发起通知；当UDM确定当前终端存在MNRF标志，则订阅模块801确定当前终端的用户状态为用户不可及。
在实施中，能够确定当前终端的用户状态的方式有许多种，凡是可以确定当前用户状态的均适用于本公开实施例。
订阅模块801确定当前终端的用户状态为用户不可及后，可以先确定订阅模块801是否已经向AMF订阅了用户可及通知，若未订阅，则订阅模块801可以向AMF订阅用户可及通知；若已订阅，则可以不向AMF订阅用户可及通知；
订阅模块801确定当前终端的用户状态为用户不可及后，也可以不确定订阅模块801是否已经向AMF订阅了用户可及通知，直接向AMF订阅用户可及通知。
订阅模块801向AMF订阅用户可及通知后，AMF与UDM之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM发送用户可及通知。
所述第一传输模块802接收到所述AMF发送的用户可及通知；且针对所述终端已设置短信无法下发标识，则所述第一传输模块802清除短信无法下发标识。
所述第一传输模块802接收到所述AMF发送的用户可及通知后，可以将之前设置的短信无法下发标识清除，若第一传输模块802针对该终端保存了对应的SMSC地址，第一传输模块802可以向该SMSC发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
第二种，所述订阅模块801向所述AMF订阅用户可及通知和用户不可及通知。
无论当前终端的用户状态如何，订阅模块801可以向所述AMF订阅两种用户通知，也即用户可及通知和用户不可及通知；
订阅模块801确定当前终端的用户状态为用户不可及后，可以先确定订阅模块801是否已经向AMF订阅了用户可及通知，若未订阅可以向AMF订阅用户可及通知；若已订阅，则可以不向AMF订阅用户可及通知；
订阅模块801确定当前终端的用户状态为用户不可及后，也可以不确定订阅模块801是否已经向AMF订阅了用户可及通知，直接向AMF订阅用户可及通知。
订阅模块801确定当前终端的用户状态为用户可及后，可以先确定订阅模块801是否已经向AMF订阅了用户不可及通知，若未订阅可以向AMF订阅用户不可及通知；若已订阅，则可以不向AMF订阅用户不可及通知；
订阅模块801确定当前终端的用户状态为用户可及后，也可以不确定订阅模块801是否已经向AMF订阅了用户不可及通知，直接向AMF订阅用户不可及通知。
订阅模块801针对终端的用户状态可以设置相应的标识以记录当前的用户状态，可以沿用现有的MNRF标志，也可以设置其他的标志信息表示当前的用户状态。
订阅模块801向AMF订阅用户可及通知和用户不可及通知后，AMF与UDM之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM发送用户可及通知或用户不可及通知。
若所述第一传输模块802接收到所述AMF发送的用户可及通知，且针对所述终端已设置短信无法下发标识，则所述第一传输模块802清除短信无法下发标识；
所述第一传输模块802接收到所述AMF发送的用户可及通知后，可以将之前针对所述终端设置的短信无法下发标识清除，若第一传输模块802中针对该终端保存了对应的SMSC地址，第一传输模块802可以向该SMSC 发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
若所述第一传输模块802接收到所述AMF发送的用户不可及通知，且所针对所述终端未设置短信无法下发标识，则所述第一传输模块802针对所述终端设置短信无法下发标识。
所述第一传输模块802接收到所述AMF发送的用户不可及通知后，可以针对所述终端设置短信无法下发标识，当SMSC需要下发短信并向UDM进行查询服务时，第一传输模块802确定当前终端的用户状态为用户不可及时，返回错误响应，并记录该SMSC地址，以便在用户状态由不可及变为可及后，可以向该SMSC发起通知，以使SMSC收到通知后，继续进行短信下发的操作。
实际应用时，所示订阅模块801及第一传输模块802可由UDM中的处理器结合通信接口实现。
基于同一发明构思，本公开实施例还提供了一种信息传输的设备，由于该设备解决问题的原理与本公开实施例信息传输的系统相似，因此该设备的实施可以参见系统的实施，重复之处不再赘述。
如图9所示，本公开实施例提供了一种信息传输的AMF，该AMF包括检测模块901和第二传输模块902：
检测模块901，配置为检测所述终端的用户动态；
第二传输模块902，配置为根据检测到的终端的用户动态和UDM订阅的用户状态的通知向所述UDM发送所述终端的用户状态的通知。
UDM向AMF订阅用户状态的情况分两种，UDM向AMF只订阅用户可及通知，UDM向AMF订阅用户可及通知和用户不可及通知；
下面就这两种情况分别进行介绍：
第一种，UDM向AMF订阅用户可及通知；
UDM向AMF订阅用户可及通知后，AMF与UDM之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM发 送用户可及通知。
其中，检测模块901检测终端的用户动态的方式有许多种，例如可以向终端发送寻呼，当接收到终端的寻呼响应后确定检测到终端的用户动态，也可以定位终端的位置，根据终端的位置移动来检测终端的用户动态，当定位到终端的位置后确定检测到终端的用户动态，若无法定位终端的位置，则确定无法检测到终端的用户动态。再比如，收到用户终端主动发起的请求，如业务请求、位置更新请求，收到请求后确定检测到终端的用户动态。
当第二传输模块902确定检测到所述终端的用户动态后向所述UDM发送用户可及通知；
由于之前终端的用户状态为不可及，也就是说，AMF之前无法连接至终端。
而若在订阅了用户可及状态后，AMF检测模块901检测到终端的用户动态后，则第二传输模块902向所述UDM发送用户可及通知，以表明此时终端可连接；
第二种，所述UDM向所述AMF订阅用户可及通知和用户不可及通知。
UDM向AMF订阅用户可及通知和用户不可及通知后，AMF与UDM之间建立对应的订阅逻辑，也就是说，当用户状态发生变化时，可以根据订阅逻辑向UDM发送用户可及通知或用户不可及通知。
当第二传输模块902确定检测到所述终端的用户动态后向所述UDM发送用户可及通知；
所述第二传输模块902确定无法检测到所述终端的用户动态后向所述UDM发送的用户不可及通知。
若在订阅了用户可及通知后，AMF可以连接至终端，检测模块901检测到终端的用户动态，则第二传输模块902向所述UDM发送用户可及通知，以表明此时终端可连接；
若在订阅了用户不可及通知后，AMF无法连接至终端，检测模块901 无法检测到终端的用户动态，则第二传输模块902向所述UDM发送用户不可及通知，以表明此时终端不可连接。
实际应用时，所述检测模块901及第二传输模块902可由AMF中的处理器结合通信接口实现。
