为解决背景技术中提到的问题，基于图1所示的架构。如图2所示，本申请提供一种UE的网络接入管理方法。该方法可用于UE根据网络接入规划信息中的移动路径信息进行移动过程中，UE的初始接入及UE发生接入网设备的切换。
为方便说明，将UE切换前接入的接入网设备称为RAN1，将UE切换后接入的接入网设备称为RAN2。
该方法包括以下步骤：
步骤201，UE根据网络接入规划信息和UE的当前位置，确定RAN1。
该网络接入规划信息包括UE的移动路径上的小区的标识，UE的移动路径上的小区包括RAN1的小区，UE的当前位置所在的小区归属于RAN1。
比如，UE的当前位置为位置A，UE根据网络接入规划信息，确定该位置A对应的小区是归属于RAN1，则UE确定RAN1为需要初始接入的RAN。
作为一种实现方法，网络接入规划信息还包括以下信息中的一个或多个：UE被允许接入的优先级、允许接入UE的移动路径上的小区的条件、UE的移动路径上的小区的频点、UE的移动路径上的小区的基于无线资源管理的同步信号区块测量时间配置(SS block based  RRM measurement timing configuration，SMTC)、UE的移动路径上的小区的系统帧号(System Frame Number，SFN)。
其中，UE被允许接入的优先级用于RAN确定UE接入的先后顺序。允许接入UE的移动路径上的小区的条件用于确定UE测量到的小区在何种条件下被允许接入。UE的移动路径上的小区的频点、UE的移动路径上的小区的SMTC、UE的移动路径上的小区的SFN可用于搜索小区。
步骤202，UE建立与RAN1之间的连接。
通过上述步骤201-步骤202，完成了UE的初始接入。并且上述过程中，UE是基于网络接入规划信息确定UE需要接入的RAN，因而可以减少小区搜索和检测的范围，有助于UE的快速成功接入。该方案简化和优化垂直行业中的终端设备接入网络的管理方法，以便于增加网络接入的可靠性，减少终端设备和网络在接入管理方面的复杂度。
由于UE的移动，UE的位置发生了变化，导致UE接入的RAN需要切换，则触发执行以下步骤203-步骤210。
步骤203，RAN1根据UE的当前位置和网络接入规划信息，确定RAN2。
需要说明的是，此时，UE的当前位置与UE在上述步骤201中初始接入时的当前位置是不同的位置，即UE的位置已经发生了移动。
这里的网络接入规划信息与上述步骤201中的网络接入规划信息相同，并且，UE的移动路径上的小区包括RAN2的小区(比如包括RAN2下的第一小区)，RAN1根据UE的当前位置确定UE即将移出其管理的网络区域并将要进入到RAN2管理的网络区域(比如将要进入RAN2下的第一小区)。
比如，UE从位置A移动至位置B。RAN1根据UE的当前位置B和网络接入规划信息，确定UE即将进入的网络小区(如第一小区)归属于RAN2，因此RAN1确定RAN2为UE接下来将要接入的RAN，即UE将切换至RAN2下的某个小区。
步骤204，RAN1向RAN2发送切换请求消息，相应地，RAN2可以接收到该切换请求消息。
该切换请求消息包括UE的上下文和网络接入规划信息。
步骤205，RAN2向RAN1发送切换配置信息，相应地，RAN1可以接收到该切换配置信息。
作为一种具体实现方法，RAN2向RAN1发送针对上述切换请求消息的切换响应消息，该切换响应消息包括上述切换配置信息。
该切换配置信息用于搜索和选择RAN2的小区，切换配置信息包括网络接入规划信息中的归属于RAN2的小区的标识。
比如，RAN2在接收到上述切换请求消息中，根据切换请求消息中的网络接入规划信息，确定网络接入规划信息中的归属于RAN2的小区的标识，这些小区中的某个小区将是UE接下来要接入的小区。因此，RAN2将网络接入规划信息中的归属于RAN2的小区的标识携带于切换配置信息中共发送至RAN1，并由RAN1发送至UE。
需要说明的是，网络接入规划信息中的归属于RAN2的小区的标识，可以是RAN2下的部分或全部小区。比如，RAN2下有3个小区，但该3个小区中只有2个属于网络接入规划信息，因此RAN2确定的网络接入规划信息中的归属于RAN2的小区的标识即为该2个小区的标识。
步骤206，RAN1向UE发送切换配置信息，相应地，UE可以接收到该切换配置信息。
作为一种具体实现方法，RAN1向UE发送无线资源控制(Radio Resource Control，RRC)配置请求消息，该RRC配置请求消息包括上述切换配置信息。
可选的，切换配置信息还包括以下信息中的一个或多个：网络接入规划信息中的归属于RAN2的小区的频点、网络接入规划信息中的归属于RAN2的小区的切换门限、UE被允许接入的优先级、随机接入前导序列(preamble)。比如，网络接入规划信息中的归属于RAN2的小区包括第一小区，这里的第一小区指的是网络接入规划信息中的归属于RAN2的任意小区，则可以理解为，上述切换配置信息包括以下信息中的一个或多个：第一小区的标识、第一小区的频点、第一小区的切换门限、UE被允许接入的优先级、随机接入前导序列(preamble)。
步骤207，UE选择RAN2的小区中的第一小区。
比如，UE基于网络接入规划信息中的归属于RAN2的小区的频点、网络接入规划信息中的归属于RAN2的小区的切换门限等信息，选择一个满足条件的最佳小区，可以是第一小区。
需要说明的是，UE选择小区(比如称为第二小区)不限于是UE即将进入的小区(即第一小区)，而可以是网络接入规划信息中的归属于RAN2的小区中任一小区，只要该小区是满足条件的最佳小区即可。
步骤208，UE向RAN2发送RRC连接请求消息。
该RRC连接请求消息包括第一小区的标识，该RRC连接请求消息用于请求接入第一小区。
步骤209，RAN2建立与UE之间的RRC连接。
可选的，在步骤209之前，RAN2确定准许UE接入RAN2的小区。
步骤210，RAN2向UE发送RRC连接响应消息，相应地，UE可以接收到该RRC连接响应消息。
该RRC连接响应消息同于通知完成切换。
通过上述步骤203-步骤210，当UE的位置发生移动时，RAN1可以根据UE的当前位置和网络接入规划信息为UE选择将要切换的RAN2，然后触发UE从网络接入规划信息中的归属于RAN2的小区中选择一个小区(称为第一小区)进行接入。上述过程中，RAN1是基于网络接入规划信息确定UE需要切换的RAN，因而可以减少小区搜索和检测的范围，有助于UE的快速成功接入。该方案简化和优化垂直行业中的终端设备接入网络的管理方法，以便于增加网络接入的可靠性，减少终端设备和网络在接入管理方面的复杂度。
作为一种实现方法，在上述步骤201之前，NVAF接收来自控制中心的UE的移动路径信息(比如，移动路径信息包括UE的移动路径上的地理位置信息)，NVAF根据网络部署信息(比如，网络部署信息包括网络部署的小区覆盖信息等)和UE的移动路径信息，确定UE的上述网络接入规划信息。然后，NVAF向核心网网元发送UE的网络接入规划信息。接着，核心网网元可以向接入网设备(如上述RAN1)和UE发送上述网络接入规划信息。如此，UE和RAN1可以获取并存储UE的网络接入规划信息。进而，后续UE可以使用网络接入规划信息，选择初始接入的RAN，以及RAN1可以根据网络接入规划信息为UE选择切换后的RAN。其中，这里的核心网网元比如包括用户面网元(如UPF)、移动性管理网元(如AMF)等。
下面结合具体示例，对上述图2所示的实施例进行详细说明。
如图3所示，为本申请提供的又一种UE的网络接入管理方法流程示意图。
本实施例描述NVAF确定UE的网络接入规划信息，并发送网络接入规划信息的过程。
方法包括以下步骤：
步骤301，控制中心(如垂直行业中心)将UE的移动路径信息提供给NVAF，移动路径信息包括UE标识、采用坐标描述的移动路径信息。
可选的，UE的移动路径信息还包括预期的时间和速度、是否支持业务连续性等。
步骤302，NVAF根据网络部署信息(网络中的每个小区覆盖区域、频点等信息)和UE的移动路径信息确定该UE的网络接入规划信息。
其中，网络接入规划信息包括：每段移动路径对应的可接入的网络小区的标识、允许UE接入的优先级、允许接入各个小区的条件(比如信号强度)、网络小区的频点、SMTC和SFN参数。
步骤303，NVAF将确定的UE的网络接入规划信息提供给服务于UE的AMF。
比如，NVAF向AMF发送UE接入配置请求(UE Access Configure Request)，携带UE的标识和UE的网络接入规划信息。
步骤304，AMF根据网络接入规划信息确定涉及的RAN，将UE的网络接入规划信息发送给RAN。
这里涉及的RAN可以是网络接入规划信息中的小区对应的所有的RAN，也可以是网络接入规划信息中的小区对应的部分RAN(如在UE发起接入请求所在位置附近的RAN)。
比如，AMF向RAN发送UE接入配置请求(UE Access Configure Request)，携带UE的标识和UE的网络接入规划信息。
步骤305，AMF将UE的网络接入规划信息发送给UE。
步骤306，AMF向NVAF确认该UE的网络接入规划已经完成配置。
比如，AMF向NVAF发送UE接入配置响应(UE Access Configure Response)，携带完成配置的指示信息。
该步骤为可选步骤。
步骤307，NVAF向控制中心确认该UE的网络接入已根据该路径完成对应的配置。
该步骤为可选步骤。
本实施例的方法可以在根据UE的预期移动信息确定UE的网络接入规划信息，并提供给UE和RAN,使接入网后续可以为该UE的网络接入提供网络服务保障。而现有技术并不支持网络根据UE的预期移动信息确定UE的网络接入规划信息并提供给UE和RAN。
如图4所示，为本申请提供的又一种UE的网络接入管理方法流程示意图。该实施例描述UE移动时的网络接入管理。该方法包括以下步骤：
步骤401，UE根据当前位置和从网络获得的网络接入规划信息，确定需要接入的网络(即RAN1)。
可选的，为了保证该UE的优先接入，UE可以使用网络提供的优先级接入。
步骤402，UE处于连接态，因UE移动需要切换，RAN1根据该UE的网络接入规划信息确定下一跳RAN2，RAN1向RAN2发送条件切换请求(Conditional Handover Request)， 其中包括UE的标识、UE的网络接入规划信息和UE的上下文(UE context)。
步骤403，RAN2根据该UE的网络接入规划信息对该UE做准许控制和相应的条件切换(conditional handover)配置，比如配置搜索和选择新的网络小区的参数：小区标识、小区频点、优先级、Preamble，小区切换门限等。
步骤404，RAN2向RAN1发送条件切换响应(Conditional Handover Response)，其中包括conditional handover配置信息。
步骤405-步骤406，RAN1通过RRC配置(RRC configuration)(包括RRC配置请求和RRC配置响应)将conditional handover配置信息提供给UE。
步骤407，UE按照conditional handover配置信息搜索和选择网络小区。
步骤408-步骤409，UE选择接入conditional handover配置信息中的网络小区，并与该小区对应的RAN2建立RRC连接(包括RRC连接请求和RRC连接响应)，完成RAN的切换。
通过该实施例，可以在UE移动时，RAN之间对UE的移动和切换进行提前处理，保障UE网络连接的可靠性和网络业务连续性；另外也可以简化UE对网络测量和选择的操作。而现有技术中的网络还不支持根据UE的网络接入规划信息对UE的移动和切换进行处理。
本申请提供的上述各种方法，是基于UE的移动路径、UE类型、网络部署和地理区域信息等为UE选择合适的网络接入规划信息，可以简化和优化网络接入的管理方法，增加网络接入的可靠性，减少UE和网络在接入管理方面的复杂度，有助于避免UE潜在的频繁变更接入小区的问题，保证了网络业务的连续性。
