本申请实施例的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本申请实施例中的具体含义。
本申请实施例提供了一种信息回填方法、网络设备及存储介质，能够实现对通信网络之间互操作的信令关联，有效提高对通信网络之间的信令的管理，提高用户感知能力，其中，本申请实施例中的信息回填方法可以应用在网络系统当中，网络系统可以包括用户设备(User Equipment，UE)和多个网元，网络设备与网元之间通信连接，并通过发送信令建立网络连接，网元可以包括移动性管理网元、基站节点和目标功能网元，移动性管理网元包括移动性管理实体(Mobility Management Entity，MME)和接入和移动性管理功能(Access and Mobility  Management Function，AMF)，目标功能网元可以包括会话管理功能(Session Management Function，SMF)、鉴权服务功能(Authentication Server Function，AUSF)和服务网关(Serving Gateway，SGW)等，基站节点包括eNB和gNB，上述可根据通信需要进行网络系统的设置，本申请实施例不对网络系统的具体结构进行限制，用户设备与网元之间、网元与网元之间、基站节点与上述两者之间通过规定的接口实现通信连接，如N1N2接口、N11接口、N12接口、S1-MME接口、S6a接口、S11接口等，接口遵循对应的标准协议。
通信网络智能运维离不开信令的采集和关联，当前现有技术大部分是针对4G信令的关联合成，随着5G系统商用开展，5G信令的关联合成技术也开始快速发展，当前的技术集中在5G信令内部关联，例如5G控制面各个接口信令关联，5G控制面和用户面关联等，在当前移动通信网络中，4G/5G网络共享用户数据的数据库信息，且5G终端兼容支持4G网络接入，因此用户设备可以在4G/5G网络之间移动，从而产生大量4G/5G网络的信令交互，网络中产生4G/5G交互的原因众多，分析困难，因此单从4G网络或者单从5G网络来分析信令，无法了解用户操作失败的真正原因，发现网络的潜在存在问题。
本申请实施例中以4G和5G之间的网络切换为例子，在满足本申请实施例要求的前提下，还可以是与3G或6G进行网络切换的场景，本申请不对其做具体限制。
当前4G/5G网络共享用户数据的数据库信息，且5G终端兼容支持4G网络接入，因此用户设备可以在4G/5G网络之间移动，从而产生大量4G/5G网络的信令交互。网络中产生4G/5G交互的原因众多，例如终端位置移动、网络信号质量差异、语音EPS回落、终端和网络选择等。一旦在4G/5G网络间操作失败，将很难在单系统信令中发现问题根源。由于4G和5G控制面信令相对独立，需要有关联信息才能够将4G/5G信令进行管理，这是4G/5G信令关联的难点所在，4G/5G信令关联的联系纽带是用户设备。每个移动用户设备都由唯一的国际移动用户识别码(International Mobile Subscriber Identity，IMSI)来标识。IMSI号码回填是4G/5G控制面信令采集解析设备的重要功能，更是4G/5G互操作中4G流程和5G流程关联的桥梁。在4G/5G核心网控制面各接口信令中，大部分接口(如S6a、S11和N11、N12等)在一个完整的会话中均至少会有一条消息携带IMSI号码，无需跨接口回填IMSI号码。但是有两个主要的关联接口例外，S1-MME接口极少出现IMSI号码，N1N2接口从不直接出现明文的IMSI号码。因此S1-MME和N1N2两个接口的IMSI号码字段，需要从其它接口关联回填，在4G/5G交互的各种场景下，信令流程涉及的接口众多且信令流程尤为复杂，需设计合理高效的算法和系统来保证IMSI号码回填准确性。在IMSI准确回填的前提下，将4G部分和5G部分的流程进行关联，生成完整的4G/5G互操作记录，作为4G/5G互操作分析的数据源。4G/5G互操作分析是4G/5G联合网络智能分析的重要功能，广泛应用于评估4G/5G用户感知，发现网络质量问题。
基于此，下面对本申请实施例进行详细说明。
本申请实施例提供了一种信息回填方法，应用于网络设备中，网络设备可以应用在网络系统中，网络系统的结构在上述实施例中已有描述，在此不在赘述，参照图1所示，本申请实施例中的信息回填方法包括但不限于步骤S110、步骤S120和步骤S130。

在一实施例中，网络设备所获取的网络系统内的信令是种类繁多的，为了将用户识别码准确回填到目标接口的信令中，当判断用户的通讯网络切换场景为连接态5G切换4G场景或连接态4G切换5G场景时，需要寻找一个与目标接口信令相关联的信令进行中继，在本申请实施例中，用户设备与第一移动性管理网元之间有信令交互，其中，目标接口为应用在用户设备与第一移动性管理网元之间的通信接口，第一信令为用户设备与第一移动性管理网元之间的一条信令，且，第一信令也为目标接口众多信令中的其中一条，因此在本申请实施例中，网络设备解析第一移动性管理网元的信令得到用户识别码和与目标接口的第一信令对应的第一关联键值，关联键值的选取依据为在第一移动性管理网元的信令和第一信令中独有的，能起到关联匹配的作用，网络设备选取其中一个具有用户识别码的第一移动性管理网元的信令进行解析，得到用户识别码，选取其中一个与第一信令关联匹配的具有第一关联键值的第一移动性管理网元的信令进行解析，得到第一关联键值，第一移动性管理网元的信令为第一移动性管理网元与其他网元之间的信令，由于第一信令也与第一移动性管理网元有关，因此二者均具有相关联的第一关联键值，以此可以根据第一关联键值将用户识别码关联回填到第一信令中，由于第一信令已经回填了用户识别码，随后网络设备可以根据具有用户识别码的第一信令，将用户识别码回填到余下的所有目标接口的信令中。
可以理解的是，本申请实施例中在将第一信令中的用户识别码关联回填到目标接口的所有信令的过程中，可以预先在获取网络系统内信令的时候，将目标接口的信令集中存储，随后在回填的过程中，可以标记第一信令，并在第一信令关联回填用户识别码后，将用户识别码回填到已存储的目标接口的所有信令中，而当网络设备将网络系统内的所有信令统一存储时，可以寻找得到众多信令中属于目标接口的信令，并进行用户识别码的回填。

可以理解的是，当用户设备的通讯网络切换场景为空闲态5G重选4G场景或空闲态4G重选5G场景时，才需要进行第一信令的中继作用，需要说明的是，当切换场景为空闲态5G重选4G场景时，网络设备可以获取S1-MME、S6a、S11、N11、N12、N26接口信令，此时目标接口为S1-MME接口，第一移动性管理网元为MME，第一通信接口为S6a接口，通过获取S6a接口的信令可以解析得到用户识别码和认证参数(RAND,AUTN)信息，并将认证参数(RAND,AUTN)信息作为第一关联键值。当切换场景为空闲态4G重选5G场景时，网络设备可以获取N1N2、N11、N12、N26、S6a接口信令，此时目标接口为N1N2接口，第一移动性管理网元为AMF，第一通信接口为N12接口，通过获取N12接口的信令可以解析得到用户识别码和认证参数(RAND,AUTN)信息，并将认证参数(RAND,AUTN)信息作为第一关联键值。

需要说明的是，当切换场景为空闲态5G重选4G场景时，网络设备可以获取S1-MME、S6a、S11、N11、N12、N26接口信令，此时目标接口为S1-MME接口，第一移动性管理网元为MME，第一通信接口为S6a接口，第一移动性管理网元分配的第一标识信息为MME UE NGAP ID，并将MME UE NGAP ID作为第二关联键值。当切换场景为空闲态4G重选5G场景时，网络设备可以获取N1N2、N11、N12、N26、S6a接口信令，此时目标接口为N1N2接口，第一移动性管理网元为AMF，第一通信接口为N12接口，第一移动性管理网元分配的第一标识信息为AMF UE NGAP ID。以AMF UE NGAP ID为例子，AMF UE NGAP ID是AMF中标识UE，每个AMF集的AMF UE NGAP ID是唯一的，在给定时间内，具有不同AMF指针值的GUAMI仅与一个AMF名称关联，因此选定其作为第二关联键值，可以查到找所有目标接口的信令。

解码模块102，解码模块102对来自采集模块101的信令进行解析，提取关键信令中的重要字段，生成关联键值，并且存储关键信令。
数据缓存模块103，缓存从触发XDR出单条件开始到结束的原始信令，并分场景缓存关联键值和关键信令的对应关系。
关联匹配模块104，关联匹配模块104提取根据数据缓存模块103缓存的信令，判断4G/5G互操作的场景，根据场景从数据缓存模块103提取关联键值进行匹配关联，回填用户识别码。

    解析所述第二移动性管理网元的信令，并得到与所述第二目标接口的所有信令对应的第四标识信息；
    将所述第四标识信息作为所述第四关联键值。
  13. 根据权利要求9所述的信息回填方法，其中，所述根据所述第四关联键值将所述用户识别码关联回填到所述第二目标接口的所有信令中，包括：
    根据所述第四关联键值和所述用户识别码建立第四映射关系表；
    根据所述第四关联键值和所述第四映射关系表，将所述用户识别码关联回填到所述第二目标接口的所有信令中。
  14. 根据权利要求2所述的信息回填方法，其中，所述根据所述关联键值将所述用户识别码关联回填到所述目标接口的所有信令中之后，所述方法还包括：
    根据回填后的所述网络系统内的信令，得到包含所述用户识别码的通信网络互操作记录。
  15. 根据权利要求2所述的信息回填方法，其中，所述根据所述关联键值将所述用户识别码关联回填到所述目标接口的所有信令中之后，所述方法还包括：
    删除所述网络系统内与所述用户识别码对应的互操作相关的信令；
    若收到关机信息，删除所述关联键值。
  16. 一种网络设备，包括：存储器、处理器，所述存储器存储有计算机程序，当所述处理器执行所述计算机程序时，执行权利要求1至15中任意一项所述的信息回填方法。
  17. 一种计算机可读存储介质，其存储有程序，当所述程序被处理器执行时，使得所述处理器执行如权利要求1至15中任意一项所述的信息回填方法。
