具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，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他实施例，都属于本公开保护的范围。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开实施例范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
出于简洁和便于理解的目的，本文在表征大小关系时，所使用的术语为“大于”或“小于”、“高于”或“低于”。但对于本领域技术人员来说，可以理解：术语“大于”也涵盖了“大于等于”的含义，“小于”也涵盖了“小于等于”的含义；术语“高于”涵盖了“高于等于”的含义，“低于”也涵盖了“低于等于”的含义。
图1是根据本公开的实施例示出的一种请求发送方法的示意流程图。本实施例所示的请求发送方法可以由终端执行，所述终端包括但不限于手机、平板电脑、可穿 戴设备、传感器、物联网设备等通信装置。所述终端可以作为用户设备与基站通信，所述基站包括但不限于非独立组网模式4系列中的5G基站gNB和增强型4G基站ng-eNB。
如图1所示，所述请求发送方法可以包括以下步骤：
在步骤S101中，在发起分析订阅请求时，响应于当前接入的基站为ng-eNB，确定可接入的第一gNB；
在步骤S102中，切换到所述第一gNB，向所述第一gNB发送所述分析订阅请求。
在一个实施例中，终端发起的分析订阅请求，主要用于请求网络侧设备基于机器学习(也可以是深度学习)得到的模型对某些数据进行数据分析，以得到分析结果并反馈给终端。
分析订阅请求所请求分析的内容可以有多种，例如可以请求分析某个网络侧设备的负载，例如可以请求分析终端是否需要切换小区，请求分析的内容并不限于示例的这几种情况，具体可以根据需要选择。分析不同内容可以采用不同的模型，也可以针对相似的内容采用相同的模型进行数据分析。每次发送分析订阅请求可以请求分析一项内容，也可以请求分析多项内容，本公开不作限制。
图2是根据本公开的实施例示出的一种网络示意图。
如图2所示，终端所处的网络包括非独立组网的网络，例如可以是4系列的组网方式，以gNB作为锚点基站，以5G核心网作为核心网，结合ng-eNB组网。
终端与gNB可以进行控制面通信和用户面通信，终端与ng-eNB可以进行用户面通信，ng-eNB与gNB可以进行控制面通信和用户面通信，gNB可以与5G核心网进行控制面通信和用户面通信，ng-eNB与5G核心网不直接通信。其中，控制面通信包括调度信令、控制信令的传输，用户面通信包括业务数据的传输。
在一个实施例中，终端在发起分析订阅请求时，可以将分析订阅请求发送至当前接入的基站，以请求基站基于模型进行数据分析。但是终端当前接入的基站可以是gNB，也可以是ng-eNB，由于gNB和ng-eNB的能力有所不同，例如gNB具有基于模型进行数据分析的能力，而ng-eNB不具有基于模型进行数据分析的能力。这就导致终端接入不同的基站时，分析过程会有所不同，以下针对这两种情况分别进行示例性说明。
在一个实施例中，在终端当前接入的基站为双连接NE-DC中的gNB时，可以向所述NE-DC中的gNB发送所述分析订阅请求。由于gNB的运算和处理能力相对较强(比ng-eNB强)，因此具有基于模型进行数据分析的能力。gNB在接收到分析订阅请求后，可以先确定分析订阅请求需要分析的内容，并确定分析该内容需要的模型，例如称作目标模型，进而确定gNB的本地是否存在目标模型。
若gNB本地存在目标模型，可以直接获取数据输入到目标模型得到分析结果，并将分析结果反馈给终端。若gNB本地不存在目标模型，可以从操作维护管理OAM(Operation Administration and Maintenance)获取目标模型，例如将所述分析订阅请求发送至OAM，OAM根据分析订阅请求确定目标模型并发送给gNB。
需要说明的是，在本公开的所有实施例中，例如上述终端发起分析订阅请求的实施例，以及后续gNB发起分析订阅请求的实施例和ng-eNB发起分析订阅请求，针对分析订阅请求进行数据分析的流程可以是相同的(不同在于如何确定进行数据分析的gNB)，因此本公开主要在此实施例中描述分析的大致过程，在后续实施例中则不再赘述。
例如使用目标模型进行数据分析，获取数据作为目标模型的输入量，所获取的数据可以来源于网络中的任意设备，例如可以来源于核心网、来源于gNB、来源于ng-eNB、来源于终端，在非地面网络中，还可以来源于卫星。进而gNB可以对获取到的数据进行预处理，例如转换为向量形式，以便输入到目标模型中。
例如分析订阅请求为请求分析某个ng-eNB(例如称作基站A)的负载时，gNB可以从基站A获取其正在进行业务的信息、接入终端的数量、接入终端的标识等，还可以从接入基站A的终端获取终端与基站A通信需要传输业务的数据量等数据，进而将获取到的数据作为模型的输入。
例如分析订阅请求为请求分析终端是否需要切换小区时，gNB可以从终端获取终端位置信息，并获取终端附近基站的信号质量信息，进而将获取到的数据作为模型的输入。
上述有关模型输入的描述，仅仅是用于示例，具体应用模型时，输入并不限于上述获取到的数据，并且基于不同的分析订阅请求，模型也不限于分析上述内容。
可见，在终端当前接入gNB的情况下，由于gNB能够基于模型进行数据分析，所以可以由gNB根据本地模型完成分析，或者根据从OAM获取到的模型完成分析。 但是在终端当前接入ng-eNB的情况下，由于ng-eNB并不能基于模型进行数据分析，将会出现一些问题。
例如终端当前接入的基站为ng-eNB，且终端当前所在位置没有5G信号覆盖，那么将会导致没有gNB为终端提供服务，来针对终端发起的分析订阅请求进行数据分析。而且，即使终端当前所在位置有5G信号覆盖，但是目前终端发起分析订阅请求并不会触发终端主动检测5G信号并切换到gNB，所以仍会导致终端发起的分析订阅请求得不到及时处理。而且，在终端发起的分析订阅请求得到不及时处理时，终端仍然可能继续发起其他分析订阅请求，导致分析订阅请求的积累，在后续终端接入gNB后，终端会将积累的大量分析订阅请求全部发送给gNB，进而导致gNB的负载急剧增加，对gNB造成了不良影响。
根据本公开的实施例，终端在发起分析订阅请求时，若当前接入的基站为ng-eNB，那么可以触发终端主动检测5G信号，并切换到gNB的流程，终端可以通过某种方式确定可接入的第一gNB，例如检测5G信号的信号强度，将信号强度大于强度阈值的5G信号对应的基站作为第一gNB，进而在确定第一gNB后，可以切换到第一gNB，并向第一gNB发送分析订阅请求，从而及时将分析订阅请求发送至能够进行基于模型进行数据分析的gNB，确保分析订阅请求及时得到处理。
在一个实施例中，所述确定可接入的第一gNB包括：检测接收信号的信号强度；确定信号强度大于强度阈值的5G信号对应的基站为所述第一gNB。
终端可以检测接收到的信号的信号强度，例如可以在确定当前接入ng-eNB的情况下，在5G频段接收信号，例如仅在5G频段接收信号，若确定存在信号强度较大，例如大于强度阈值的5G信号，那么可以将该5G信号对应的基站确定为第一gNB，并切换到第一gNB，将分析订阅请求发送至第一gNB，由第一gNB针对分析订阅请求完成分析。
图3是根据本公开的实施例示出的另一种请求发送方法的示意流程图。如图3所示，在一个实施例中，所述方法还包括：
在步骤S301中，若未检测到信号强度大于强度阈值的5G信号，请求操作维护管理OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB；
在步骤S302中，向所述第二gNB发送所述分析订阅请求。
在一个实施例中，当终端当前所在位置没有5G信号覆盖，或者即使有5G信 号覆盖，但是5G信号强度较弱，例如小于或等于强度阈值，那么终端即使接入5G基站也难以保证通信质量，所以可以仍保持接入ng-eNB，并通过ng-eNB向OAM发送gNB确定请求(其中可以携带有所述分析订阅请求)，以请求OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB，并将分析订阅请求发送至第二gNB，从而由第二gNB针对分析订阅请求完成分析。
其中，OAM确定第二gNB的方式根据需要进行选择，例如可以在终端能够接入的gNB中，确定能够针对分析订阅请求进行数据分析的第二gNB，或者确定负载较低的gNB作为第二gNB，并将能够针对分析订阅请求进行数据分析的目标模型发送至确定的gNB。具体方式在后续有关OAM执行操作的实施例中进行具体描述。
图4是根据本公开的实施例示出的一种基站确定方法的示意流程图。本实施例所示的基站确定方法可以由OAM执行，OAM可以与网络中的基站通信，例如可以与NE-DC中的gNB和ng-eNB通信，所述基站可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。所述基站包括但不限于非独立组网模式4系列中的5G基站gNB和增强型4G基站ng-eNB。
如图4所示，所述基站确定方法可以包括以下步骤：
在步骤S401中，接收ng-eNB发送的分析订阅请求，确定能够针对所述分析订阅请求进行数据分析的第二gNB；
在步骤S402中，确定所述第二gNB；
在步骤S403中，向所述第二gNB和所述ng-eNB发送数据分析配置信息，其中，所述分析配置信息用于指示由所述第二gNB将针对所述分析订阅请求的分析结果发送至所述ng-eNB。
在一个实施例中，所述分析订阅请求可以是所述ng-eNB发起的，也可以是接入所述ng-eNB的终端发起并发送至所述ng-eNB的。
当终端发起分析订阅请求时，若终端当前接入的基站为ng-eNB，且未检测到信号强度大于强度阈值的5G信号，可以通过ng-eNB向OAM发送分析订阅请求，以请求OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB。
当ng-eNB发起分析订阅请求时，由于ng-eNB不能根据模型进行数据分析，那么可以向OAM发送分析订阅请求，以请求OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB。
OAM在接收到分析订阅请求后，可以确定所述第二gNB，并向确定的gNB和发送分析订阅请求的ng-eNB发送数据分析配置信息，通过数据分析配置信息指示由所述第二gNB将针对所述分析订阅请求的分析结果发送至所述ng-eNB。
第二gNB接收到OAM发送的数据分析配置信息后，可以将针对所述分析订阅请求的分析结果发送至所述ng-eNB。ng-eNB接收到OAM发送的数据分析配置信息后，在第二gNB为了进行数据分析需要获取数据时，可以将第二gNB所需获取的数据发送给第二gNB，还可以从网络中的其他基站获取第二gNB所需获取的数据并将其发送给第二gNB，ng-eNB还可以接收第二gNB发送的分析结果，在分析订阅请求为终端发起时，ng-eNB还可以进一步将分析结果发送至终端。
据此，当接入ng-eNB的终端或ng-eNB在发起分析订阅请求时，可以请求OAM确定第二gNB，并通过第二gNB针对分析订阅请求进行数据分析，进而将得到的分析结果发送至终端或ng-eNB，从而确保分析订阅请求及时得到处理。
图5是根据本公开的实施例示出的另一种基站确定方法的示意流程图。如图5所示，所述确定所述第二gNB包括：
在步骤S501中，确定是否存在被分配了目标模型的目标gNB，其中，所述目标模型适用于针对所述分析订阅请求进行数据分析；
在步骤S502中，当存在所述目标gNB时，确定所述目标gNB为所述第二gNB。
在一个实施例中，OAM可以先确定适用于针对所述分析订阅请求进行数据分析的目标模型，进而判断是否存在被分配了目标模型的目标gNB，若存在目标gNB，那么通过目标gNB即可完成对分析订阅请求的数据分析，因此可以确定目标gNB为第二gNB。
需要说明的是，确定目标gNB所需考虑的条件，包括但不限于上述被分配了目标模型，例如还可以考虑信号是否覆盖终端当前所在位置，若信号覆盖终端当前所在位置，才确定其为目标gNB，以确保目标gNB能够作为第二gNB与终端通信。
图6是根据本公开的实施例示出的又一种基站确定方法的示意流程图。如图6所示，所述方法还包括：
在步骤S601中，当不存在所述目标gNB时，确定空闲gNB为所述第二gNB，将所述目标模型发送至所述第二gNB。
在一个实施例中，OAM可以先确定适用于针对所述分析订阅请求进行数据分析的目标模型，进而判断是否存在被分配了目标模型的目标gNB，若不存在目标gNB，可以确定空闲gNB为所述第二gNB，并将所述目标模型发送至所述第二gNB，以便确定的二gNB能够尽快完成对分析订阅请求的数据分析。
其中，确定空闲gNB的方式包括但不限于根据gNB的负载、接入终端数量等确定，例如可以确定负载低于负载阈值的gNB为空闲gNB，或者确定接入终端数量少于数量阈值的gNB为空闲gNB。
图7是根据本公开的实施例示出的一种请求发送方法的示意流程图。本实施例所示的请求发送方法可以由NE-DC中的基站ng-eNB执行，ng-eNB可以与终端和OAM通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图7所示，所述请求发送方法可以包括以下步骤：
在步骤S701中，在发起分析订阅请求时或接收到终端发送的分析订阅请求时，将所述分析订阅请求发送至OAM，以请求所述OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB；
在步骤S702中，接收所述第二gNB发送的针对所述分析订阅请求的分析结果。
在一个实施例中，当终端发起分析订阅请求时，若终端当前接入的基站为ng-eNB，且未检测到信号强度大于强度阈值的5G信号，可以通过ng-eNB向OAM发送分析订阅请求，以请求OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB。
当ng-eNB自身发起分析订阅请求时，由于ng-eNB不能根据模型进行数据分析，那么可以向OAM发送分析订阅请求，以请求OAM确定能够针对所述分析订阅请求进行数据分析的第二gNB。
OAM在接收到分析订阅请求后，可以确定所述第二gNB，并向确定的gNB和发送分析订阅请求的ng-eNB发送数据分析配置信息，通过数据分析配置信息指示由所述第二gNB将针对所述分析订阅请求的分析结果发送至所述ng-eNB。
第二gNB接收到OAM发送的数据分析配置信息后，可以将针对所述分析订阅请求的分析结果发送至所述ng-eNB。ng-eNB接收到OAM发送的数据分析配置信息后，ng-eNB可以接收gNB发送的分析结果，在分析订阅请求为终端发起时，还可以进一 步将分析结果发送至终端。
据此，终端或ng-eNB在发起分析订阅请求时，可以请求OAM确定第二gNB，并通过第二gNB针对分析订阅请求进行数据分析，进而将得到的分析结果发送至终端或ng-eNB，从而确保分析订阅请求及时得到处理。
图8是根据本公开的实施例示出的另一种请求发送方法的示意流程图。如图8所示，在接收所述第二gNB发送的针对所述分析订阅请求的分析结果之前，所述方法还包括：
在步骤S801中，接收所述OAM发送的数据分析配置信息；
在步骤S802中，根据所述数据分析配置信息确定由所述第二gNB将针对所述分析订阅请求的分析结果发送至所述ng-eNB。
在一个实施例中，OAM在确定第二gNB后，可以向第二gNB和ng-eNB发送数据分析配置信息，通过数据分析配置信息指示ng-eNB，后续由第二gNB针对所述分析订阅请求进行数据分析，使得ng-eNB可以接收第二gNB发送的分析结果；相应地，也可以使得第二gNB确定需要将分析结果发送至ng-eNB。
例如ng-eNB可以先与第二gNB建立基站间接口，然后通过基站间接口从第二gNB接收分析结果。
图9是根据本公开的实施例示出的又一种请求发送方法的示意流程图。如图9所示，所述方法还包括：
在步骤S901中，接收所述第二gNB发送的模型推理数据请求，其中，所述模型推理数据请求用于请求从所述ng-eNB获取用于针对所述分析订阅请求进行数据分析的数据；
在步骤S902中，将用于针对所述分析订阅请求进行数据分析的数据发送至所述第二gNB。
在一个实施例中，OAM在确定第二gNB后，可以向第二gNB和ng-eNB发送数据分析配置信息，通过数据分析配置信息指示ng-eNB，后续由第二gNB针对所述分析订阅请求进行数据分析，进而后续在第二gNB为了进行数据分析需要从ng-eNB获取数据时，可以将第二gNB所需获取的数据发送给第二gNB，还可以从网络中的其他基站获取第二gNB所需获取的数据并将其发送给第二gNB。
在一个实施例中，gNB也可以发起分析订阅请求，当gNB发起分析订阅请求后，可以先确定针对分析订阅请求进行数据分析所要用到的目标模型，若gNB本地存在目标模型，则可以直接使用目标模型进行数据分析，若gNB本地不存在目标模型，则可以向OAM发送请求，以从OAM获取目标模型进行数据分析。
在以上实施例中，主要涉及四种情况，分别为：终端发起分析订阅请求，且当前接入gNB；终端发起分析订阅请求，且当前接入ng-eNB；ng-eNB发起分析订阅请求；gNB发起分析订阅请求。以下通过交互示意图针对这四种情况进行分别描述。
图10是根据本公开的实施例示出的一种gNB发起分析订阅请求时的交互示意图。
如图10所示，在gNB发起分析订阅请求时，可以先根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而查询本地是否存在目标模型。
若本地存在模型，可以直接通过目标模型进行数据分析，以得到分析结果。若本地不存在目标模型，可以向OAM发送分析订阅请求，OAM可以根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而将目标模型发送给gNB。
gNB为了进行数据分析，可以从其他基站获取数据作为目标模型的输入，例如可以向网络中的其他gNB，其他ng-eNB发送数据获取请求，其他基站可以将gNB需要获取的数据发送给gNB，该过程包含gNB收集数据、其他基站向gNB上报数据、以及gNB对数据进行预处理等操作。
进而gNB可以将获取到的数据输入到目标模型中得到分析结果，然后可以根据分析结果执行相应策略调整。例如分析订阅请求需要分析的内容为确定适合终端切换的目标基站，根据分析结果可以确定目标基站，那么执行的策略调整可以是向终端发送指示，指示终端切换到目标基站。
需要说明的是，在本公开的所有实施例中，其他gNB是指一个或多个gNB，其他ng-eNB是指一个或多个ng-eNB。
图11是根据本公开的实施例示出的一种ng-eNB发起分析订阅请求时的交互示意图。
如图11所示，在ng-eNB发起分析订阅请求时，由于ng-eNB没有能力根据模型进行数据分析，所以可以将分析订阅请求发送至OAM，可以直接发送至OAM，也可以通过相邻的gNB发送至OAM。
OAM接收到分析订阅请求后，可以先根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而确定是否存在已部署了目标模型的gNB。
若不存在已部署了目标模型的gNB，可以选择空闲的gNB作为第二gNB，并将目标模型发送至第二gNB。若存在已部署了目标模型的gNB，可以直接将该gNB作为第二gNB。进而OAM可以向ng-eNB和第二gNB发送数据分析配置信息，以指示接下来由第二gNB进行数据分析。
第二gNB为了进行数据分析，可以从其他基站获取数据作为目标模型的输入，例如可以向发起分析订阅请求的ng-eNB、网络中的其他gNB、其他ng-eNB发送数据获取请求，这些基站可以将第二gNB需要获取的数据发送给第二gNB，该过程包含第二gNB收集数据、基站向第二gNB上报数据、以及第二gNB对数据进行预处理等操作。
进而第二gNB可以将获取到的数据输入到目标模型中得到分析结果，并将分析结果发送给发起分析订阅请求的ng-eNB，ng-eNB可以根据分析结果执行相应策略调整。例如分析订阅请求需要分析的内容为确定适合终端切换的目标基站，根据分析结果可以确定目标基站，那么执行的策略调整可以是向终端发送指示，指示终端切换到目标基站。
图12是根据本公开的实施例示出的一种终端发起分析订阅请求时的交互示意图。
如图12所示，在终端发起分析订阅请求时，若终端当前接入的基站为gNB，可以将分析订阅请求发送至gNB。gNB可以先根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而查询本地是否存在目标模型。
若本地存在模型，可以直接通过目标模型进行数据分析，以得到分析结果。若本地不存在目标模型，可以向OAM发送分析订阅请求，OAM可以根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而将目标模型发送给gNB。
gNB为了进行数据分析，可以从其他基站获取数据作为目标模型的输入，例如可以向终端以及网络中的其他gNB、其他ng-eNB发送数据获取请求，终端和其他基站可以将gNB需要获取的数据发送给gNB，该过程包含gNB收集数据、其他基站向gNB上报数据、以及gNB对数据进行预处理等操作。
进而gNB可以将获取到的数据输入到目标模型中得到分析结果，并将分析结 果发送至终端，终端可以根据分析结果执行相应策略调整。例如分析订阅请求需要分析的内容为确定适合终端切换的目标基站，根据分析结果可以确定目标基站，那么执行的策略调整可以是终端向目标基站切换。
图13是根据本公开的实施例示出的另一种终端发起分析订阅请求时的交互示意图。
如图13所示，在终端发起分析订阅请求时，若终端当前接入的基站为ng-eNB，由于ng-eNB没有能力根据模型进行数据分析，所以可以先确定是否存可接入的第一gNB，例如检测5G信号的信号强度，将信号强度大于强度阈值的5G信号对应的基站作为第一gNB。
若存在可接入的第一gNB，可以切换到第一gNB，并向第一gNB发送分析订阅请求，由第一gNB进行数据数据分析，分析过程与上述gNB进行数据分析的过程基本相同，此处不再赘述。
若不存在可接入的第一gNB，可以通过当前接入的ng-eNB向OAM发送分析订阅请求，可以由ng-eNB直接发送至OAM，也可以通过ng-eNB相邻的gNB发送至OAM。
OAM接收到分析订阅请求后，可以先根据分析订阅请求需要分析的内容，确定用于分析的目标模型，进而确定是否存在已部署了目标模型的gNB。
若不存在已部署了目标模型的gNB，可以选择空闲的gNB作为第二gNB，并将目标模型发送至第二gNB。若存在已部署了目标模型的gNB，可以直接将该gNB作为第二gNB。进而OAM可以向ng-eNB和第二gNB发送数据分析配置信息，以指示接下来由第二gNB进行数据分析。
第二gNB为了进行数据分析，可以从终端以及网络中的其他基站获取数据作为目标模型的输入，例如可以向终端、终端当前接入的ng-eNB、网络中的其他gNB、其他ng-eNB发送数据获取请求，这些基站和终端可以将第二gNB需要获取的数据发送给第二gNB，该过程包含第二gNB收集数据、终端和基站向第二gNB上报数据、以及第二gNB对数据进行预处理等操作。
进而第二gNB可以将获取到的数据输入到目标模型中得到分析结果，并将分析结果经由ng-eNB发送给终端，终端可以根据分析结果执行相应策略调整。例如分析订阅请求需要分析的内容为确定适合终端切换的目标基站，根据分析结果可以确定 目标基站，那么执行的策略调整可以是终端向目标基站切换。
