具体实施方式
5G AP定义三类小区：开放小区、混合小区以及封闭小区，其中：开放小区是指任何用户设备都能够接入的小区，相当于宏站定义的小区；封闭小区为PUG小区，只支持授权用户设备接入；混合小区中，任何小区都能够接入，但是会优先保障授权用户设备的服务质量。
对于PUG小区，可以采用不同的方法授权用户设备的接入。在实际应用中，可以采用基于密钥的方法授权用户设备接入，或者采用基于同步授权的方法授权用户设备接入。在采用基于密钥的方法授权用户设备接入时，用户设备可以采用获取到的要完成授权。在采用基于同步授权的方法授权用户设备接入时，授权信息在核心网与授权用户设备之间完成同步。
针对接入控制和计费方式，通常包括如下场景：1、开放小区，所有通过5G AP接入的用户设备都单独计费；2、混合小区或者封闭 小区，例如饭店、酒店等场景，由工作人员告诉顾客密钥，顾客通过密钥使用用户设备接入，不额外单独计费；3、混合小区或者封闭小区，私人部署，针对部分用户设备需要密钥接入并单独计费，针对另一部分用户设备不需要密钥接入也不单独计费，如医院等场景，医护人员对应的用户设备无需密钥接入也不单独计费；4、混合小区或者封闭小区，家庭部署，房主及家人无需付费，访客需要密钥才能访问，也无需额外付费。
然而，在5G AP所定义的三类小区中，用户设备可能并不知道哪些小区是开放小区，哪些小区是封闭小区或者混合小区。因此，用户设备可能无法获知是否有权限接入测量得到的小区，存在用户设备无法正常接入的情况。
在本发明实施例中，获取网络接入授权控制信息，并将获取到的网络接入授权控制信息发送至用户设备，从而使得用户设备获知网络接入授权控制信息，进而使得用户设备根据相应的接入方式接入，有效避免用户设备无法正常接入网络的情况出现。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
本发明实施例提供了一种用户设备移动性管理方法，参照图1，以下通过具体步骤进行详细说明。
在本发明实施例中，下述步骤S101～步骤S102所提供的用户设备移动性管理方法可以由接入点设备所执行。具体的，下述步骤S101～步骤S102可以由接入点设备中具有数据处理能力的芯片所执行，或者由接入点设备中包含数据处理芯片的芯片模组所执行。
步骤S101，获取网络接入授权控制信息。
在具体实施中，网络接入授权控制信息可以用于判断用户设备是否用权限接入网络。网络接入授权控制信息可以由接入点设备获取。接入点设备可以为5G AP接入点设备。
步骤S102，发送所述网络接入授权控制信息。
在具体实施中，可以由接入点设备通过广播的方式向用户设备发送网络接入授权控制信息。用户设备可以接收广播，并从中获取网络接入授权控制信息，进而确定目标小区是否需要权限验证，或者是否有权限接入。
在本发明实施例中，接入点设备可以通过系统消息块(SIB)1向用户设备广播网络接入授权控制信息。
可以理解的是，接入点设备也可以采用其他的方式向用户设备发送网络接入授权控制信息，如通过高层信令向用户设备发送网络接入授权控制信息，本发明实施例不做赘述。
在具体实施中，根据用户设备接入网络接入CUG小区的方式不同，网络接入授权控制信息可以不同。
在本发明实施例中，若用户设备使用密钥接入CUG小区，则网络接入授权控制信息可以包括封闭用户组(Closed User Group，CUG)标识以及消息完整性校验信息；若用户设备基于同步授权的方法接入CUG小区，则网络接入授权控制信息可以包括封闭用户组(Closed User Group，CUG)标识。
在具体实施中，用户设备在接收到网络接入授权控制信息之后，可以从中获取CUG标识，进而确定所要驻留的小区(以下简称目标小区)是否为封闭小区还是混合小区。
在本发明实施例中，CUG标识可以用于表征进行小区选择或者小区重选的目标小区的类型。进一步而言，CUG标识可以用于表征目标小区是封闭小区、混合小区还是开放小区。
在具体实施中，同一个用户设备对应的多个CUG小区可以使用相同的CUG标识。也就是说，对应于房间、工厂、公司等不同的CUG小区，可以使用相同的CUG标识。可以理解的是，不同的CUG小区对应的CUG标识也可以不同。
在本发明实施例中，消息完整性校验信息可以为MIC值。MIC值可以根据CUG密钥生成，或者根据CUG密钥的派生密钥生成。MIC值也可以为基于CUG密钥以及系统消息中除MIC之外的其他所有信息生成的完整性校验密钥，或者根据CUG密钥的派生密钥以及系统消息中除MIC之外的其他所有信息生成的完整性校验码。CUG密钥即为用户设备接入目标小区所需的密钥，也即用户设备在接入该CUG小区时需要输入相应的密钥才能够获得授权。
例如，在饭店、酒店等场景，由工作人员告诉顾客密钥，顾客在用户设备上输入密钥接入CUG小区。
在具体实施中，若用户设备确定当前所要驻留的小区为CUG小区，且用户设备基于密钥的方法接入CUG小区，则用户设备可以尝试使用预先存储的密钥对MIC信息进行验证，以确定是否能够接入CUG小区。若用户设备使用预先存储的密钥对MIC信息通过验证，则用户设备可以接入该CUG小区。
在具体应用中，网络接入授权控制信息可能会发生更新。网络接入授权控制信息发生更新，意味着用户设备需要重新获取网络接入授权控制信息。
当接入点设备确定网络接入授权控制信息发生更新时，可以向用户设备发送第一指示信息，第一指示信息用于指示网络接入授权控制信息发生变更。用户设备在接收到第一指示信息后，即可获知网络接入授权控制信息发生变更。
在具体实施中，接入点设备可以向用户设备下发寻呼消息，由寻呼消息承载第一指示信息。具体而言，接入点设备可以在寻呼消息中设置新的寻呼原因值，通过新的寻呼原因值来承载第一指示信息。
在具体实施中，接入点设备也可以向用户设备下发下行控制信息(Downlink Control Information，DCI)，在下行控制信息中承载有第一指示信息。
可以理解的是，接入点设备也可以通过其他方式向用户设备下发第一指示信息，并不仅限于上述实施例中提供的示例。
在本发明实施例中，若用户设备基于密钥接入CUG小区，则接入点设备在检测到CUG小区的密钥更新后，可以向用户设备下发第一指示信息，以告知用户设备输入新的密钥，完成CUG小区驻留。用户设备在接收到第一指示信息后，可以获取新的密钥并输入。
在具体应用中，若CUG小区的密钥更新，则用户可以向后台工作人员索取密钥，或者向后台服务器索取密钥。
例如，CUG小区由酒店部署，用户可以向酒店服务人员询问更新后的CUG小区的密钥，进而输入更新后的密钥进行相应的接入。
在具体实施中，若接入点设备判定用户设备未提供有效的网络接入授权控制信息时，可以将用户设备重定向到其他小区，或者拒绝该用户设备的接入。当接入点设备拒绝该用户设备的接入时，可以向用户设备发送拒绝原因值，使得用户设备能够获知被拒绝接入的具体原因。
例如，拒绝原因值可以为“密钥错误”。用户设备在接收到拒绝原因值之后，即可获知无法接入CUG小区的原因为密钥错误。
在本发明实施例中，若接入点设备判定用户设备输入的密钥错误，则接入点设备可以判定用户设备没有提供有效的网络接入授权控制信息。此时接入点设备可以将用户设备重定向至其他的小区，或者拒绝用户设备的接入。
在具体实施中，若用户设备基于同步授权的方法接入CUG小区，则当接入点设备检测到网络接入授权控制信息发生变化时，也可以向用户设备发送第一指示信息。用户设备在接收到第一指示信息后，即可获知网络接入授权控制信息发生变化。
在本发明实施例中，用户设备在获知网络接入授权控制信息发生变化后，可以重新读取网络接入授权控制信息表，或者请求网络发送 更新后的网络接入授权控制信息表。
在具体实施中，在网络接入授权控制信息完成变更之前，接入点设备仍可以继续转发用户设备对应的寻呼消息，以保证用户设备可达。相应地，网络侧也需要按照网络接入授权控制信息没有发生变化的情况继续向用户设备发送寻呼消息。
需要说明的是，本发明实施例中所述的“接入”可以是指用户设备驻留到网络，也可以是指用户设备与网络建立连接。
由此可见，获取网络接入授权控制信息，并将获取到的网络接入授权控制信息发送至用户设备，从而使得用户设备获知网络接入授权控制信息，进而使得用户设备根据相应的接入方式接入，有效避免用户设备无法正常接入网络的情况出现。
本发明实施例还提供了另一种用户设备移动性管理方法，参照图2，以下通过具体步骤进行详细说明。

在本发明实施例中，接入点设备可以通过系统消息块(SIB)1向用户设备广播网络接入授权控制信息。用户设备接收接入点设备通过SIB1发送的网络接入授权控制信息。
可以理解的是，接入点设备也可以采用其他的方式向用户设备发送网络接入授权控制信息，如通过高层信令向用户设备发送网络接入授权控制信息，本发明实施例不做赘述。
在具体实施中，根据用户设备接入网络接入CUG小区的方式不同，网络接入授权控制信息可以不同。
在本发明实施例中，若用户设备使用密钥接入CUG小区，则网络接入授权控制信息可以包括封闭用户组(Closed User Group，CUG)标识以及消息完整性校验信息；若用户设备基于同步授权的方法接入CUG小区，则网络接入授权控制信息可以包括封闭用户组(Closed User Group，CUG)标识。

现有技术中，在进行小区切换时，源基站并不知道用户设备是否能够切换至PUG小区。
在本发明实施例中，用户设备确定目标小区的信息，目标小区的信息能够表征该用户设备是否为目标小区的授权用户，将目标小区的信息发送至源基站。源基站根据用户设备发送的目标小区的信息，即可获知用户设备是否具有相应的权限驻留在目标小区中，进而确定是否将用户设备切换至目标小区中。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
本发明实施例提供了另一种用户设备移动性管理方法，参照图5，以下通过具体步骤进行详细说明。
在本发明实施例中，下述步骤S501～步骤S502所提供的用户设备移动性管理方法可以由用户设备所执行。具体的，下述步骤S501～步骤S502可以由用户设备中具有数据处理能力的芯片所执行，如基带芯片；或者由用户设备中包含基带芯片的芯片模组所执行。
步骤S501，确定目标小区的信息。
在具体应用中可知，源基站在为用户设备配置的邻区测量配置中，可能没有为用户设备配置目标小区的测量配置，因此，源基站可以配置用户设备反馈目标小区的信息。
在具体实施中，可以由源基站设备向用户设备下发第一指示信息，第一指示信息可以用于触发用户设备反馈目标小区的信息。用户 设备可以接收源基站下发的第一指示信息，根据源基站下发的第一指示信息确定目标小区的信息。
在本发明实施例中，源基站可以通过高层信令向用户设备下发第一指示信息，也可以通过下行控制信息(Downlink Control Information，DCI)向用户设备下第一指示信息，还可以通过MAC CE等其他类型的信令向用户设备下发第一指示信息。其中，高层信令可以为无线资源控制(Radio Resource Control，RRC)信令。
在具体实施中，目标小区的信息可以包括目标小区的标识信息以及目标小区的授权信息，在本发明实施例中，目标小区的标识信息可以用于表征目标小区是哪一个小区，目标小区的授权信息可以用于表征用户设备是否为目标小区的授权用户。
需要说明的是，若用户设备判断自身不是目标小区的授权用户，则用户设备可以不生成目标小区的信息，后续也无需发送目标小区的信息。因此，可以当用户设备判断自身为目标小区的授权用户时，才确定目标小区的信息，并执行后续发送目标小区的信息的操作。
也就是说，若用户设备没有执行确定目标小区的信息的操作，则可以确认该用户设备不是目标小区的授权用户。仅在用户设备为目标小区的授权用户时，该用户设备才确定目标小区的信息。此时，所述目标小区的授权信息可以用于表征用户设备是所述目标小区的授权用户。
在具体实施中，目标小区可以为封闭小区或混合小区。其中，封闭小区只支持授权用户设备接入；混合小区中，任何用户设备都能够接入，但是会优先保障授权用户设备的服务质量。
在本发明实施例中，目标小区可以为用户设备所能够驻留的封闭用户组(Closed User Group，CUG)小区。
例如，当前覆盖用户设备1的CUG小区为CUG小区1，用户设备1不是CUG小区1的授权用户。用户设备1在接收到第一指示信 息后，向源基站反馈的目标小区的标识信息为：CUG小区的标识信息为1；向源基站反馈的目标小区的该用户设备1不是授权用户设备。
又如，当前覆盖用户设备2的CUG小区为CUG小区1，用户设备2是CUG小区1的授权用户。用户设备2在接收到第一指示信息后，向源基站反馈的目标小区的授权信息为：CUG小区的标识信息为1，该用户设备2是CUG小区1的授权用户设备。
步骤S502，发送所述目标小区的信息。
在具体实施中，用户设备在确定目标小区的授权信息之后，可以发送所确定的目标小区的信息。在本发明实施例中，可以将所确定的目标小区的信息发送至源基站。
在具体实施中，源基站在接收到用户设备反馈的目标小区的信息之后，可以获知用户设备是否能够驻留在目标小区。源基站在确定将用户设备切换至目标小区之后，可以向目标小区对应的目标基站发送目标小区的信息。
源基站在确定将用户设备切换至目标小区之后，可以向用户设备发送切换指示信息。用户设备在接收到切换指示信息之后，可以将目标小区的授权信息发送至目标基站。
目标基站在接收到源基站发送的目标小区的信息以及用户设备发送的目标小区的授权信息之后，即可对用户设备的授权关系进行判断，以确定该用户设备是否为授权用户，进而确定该用户设备是否能够驻留到目标小区。
在本发明实施例中，源基站可以为宏基站，也可以为5G接入点设备或者其他类型的基站。
在具体实施中，用户设备可以通过密钥接入目标小区。此时，用户设备向源基站发送的目标小区的信息中，除了目标小区的标识信息以及目标小区的授权信息之外，还可以包括目标小区对应的消息完整性校验信息。
在本发明实施例中，消息完整性校验信息可以为消息完整性校验(Messages Integrity Check，MIC)值。MIC值可以根据CUG密钥生成，或者根据CUG密钥的派生密钥生成。MIC值也可以为基于CUG密钥以及系统消息中除MIC之外的其他所有信息生成的完整性校验密钥，或者根据CUG密钥的派生密钥以及系统消息中除MIC之外的其他所有信息生成的完整性校验码。CUG密钥即为用户设备接入目标小区所需的密钥，也即用户设备在接入该CUG小区时需要输入相应的密钥才能够获得授权。
在本发明实施例中，目标小区的授权信息还可以包括消息完整性校验信息对应的随机数。此时，用户设备还可以将消息完整性校验信息对应的随机数发送至源基站。
此时，源基站接收到的用户设备发送的目标小区的信息包括：目标小区的标识信息，目标小区的授权信息，目标小区的消息完整性校验信息，消息完整性校验信息对应的随机数。用户设备向目标基站发送的目标小区的信息包括：目标小区的授权信息，目标小区的消息完整性校验信息，消息完整性校验信息对应的随机数。
在具体实施中，在4步竞争随机接入信道(Random Access Channel，RACH)时，用户设备可以使用msg3或者msg5向目标基站发送目标小区的授权信息。在非竞争RACH时，在RAR后的第一个上行数据传输时，向目标基站发送目标小区的授权信息。在两步RACH时，用户设备可以在msgA中携带目标小区的授权信息并发送至目标基站。
在具体实施中，用户设备也可以基于同步授权的方法接入目标小区。用户设备在接收切换指示信息之后，向目标基站发送目标小区的授权信息。目标基站可以根据自身存储的同步授权关系，判断是否允许该用户设备驻留。目标基站也可以向核心网发送请求，由核心网判断是否允许该用户设备驻留。
在本发明实施例中，目标基站也可以向核心网请求授权信息。核 心网在接收到目标基站的请求后，向目标基站发送授权信息，由目标基站判断是否允许用户设备驻留。
在具体实施中，在用户设备切换至目标小区之前，核心网仍需要继续按照用户设备没有发生切换的情况继续发送寻呼消息，以保证用户设备可达。在用户设备切换至目标小区之后，核心网可以按照用户设备切换完成的情况发送寻呼消息，以保证用户设备可达。
由此可见，在本发明实施例中，用户设备确定目标小区的信息，目标小区的信息能够表征该用户设备是否为目标小区的授权用户，将目标小区的信息发送至源基站。源基站根据用户设备发送的目标小区的信息，即可获知用户设备是否具有相应的权限驻留在目标小区中，进而确定是否将用户设备切换至目标小区中。

在具体实施中，源基站在接收到用户设备反馈的目标小区的信息之后，可以获知用户设备是否能够驻留在目标小区。源基站在确定将用户设备切换至目标小区之后，可以向目标小区对应的目标基站发送目标小区的信息。
源基站在确定将用户设备切换至目标小区之后，可以向用户设备发送切换指示信息。用户设备在接收到切换指示信息之后，可以将目标小区的授权信息发送至目标基站。
