切片选择在两个过程中执行，一是注册过程，在该过程中网络选择为UE(User Equipment，用户设备)服务的AMF(Access and Mobility Management Function，接入和移动管理功能)以及确定允许UE使用的网络切片；二是PDU(Protocol Data Unit，协议数据单元)会话建立过程，在该过程中AMF选择切片以及切片内的SMF(Session Management Function，会话管理功能)，然后SMF负责完成用户面连接的建立。

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作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。
参见图1，图1是本公开实施例提供的信息处理方法的流程图，应用于NWDAF，如图1所示，包括以下步骤：
步骤101、获取切片的信息。
在本公开实施例中，所述切片的信息包括：从OAM或RAN节点或UPF获得的切片的速率，从目标网元获得的平均UE数或者峰值UE数，从所述目标网元获得的平均PDU会话数或者峰值PDU会话数，从所述目标网元获得的平均切片速率或者峰值切片速率。其中，所述目标网元可以是PCF、AMF、NSSF，NSQ等。
例如，NWDAF可向OAM或RAN节点或UPF订阅切片的速率，从而从OAM或RAN节点或UPF获得的切片的速率。
例如，目标网元可对某个时间段内的UE数或者PDU会话等进行统计，从而获得平均UE数或者峰值UE数，以及平均PDU会话数或者峰值PDU会 话数。
例如，如果目标网元为NSSF，NSQ等，则目标网元可请求AMF或SMF提供平均切片速率或峰值切片速率，AMF请求RAN提供平均切片速率或峰值切片速率，SMF请求UPF提供平均切片速率或峰值切片速率。如果目标网元为AMF或SMF，则可直接获取该信息。因此，目标网元可向NWDAF发送平均切片速率或峰值切片速率。
对于AMF集合/切片覆盖区域，AMF集合/切片覆盖区域内某个AMF请求其他AMF提供平均切片速率或峰值切片速率，然后向NWDAF提供集合或区域的平均切片速率或峰值切片速率。覆盖区域内的某个SMF请求其他SMF提供平均切片速率或峰值切片速率，然后向NWDAF提供集合或区域的平均切片速率或峰值切片速率。如果目标网元为AMF或SMF，则可直接获取该信息，并将其发送给NWDAF。如果目标网元为NSSF，NSQ等，则可从AMF或者SMF请求到平均切片速率或峰值切片速率，并发送给NWDAF。
步骤102、根据所述切片的信息，确定所述切片内UE数相关的分析结果和切片内PDU会话数相关的分析结果中的至少一项。
其中，UE数相关的分析结果可以是UE数的范围，最大UE数，最大UE数的范围，连接态UE数的范围，最大连接态UE数，空闲态UE数的范围，最大空闲态UE数，最大漫游UE数，最大漫游UE数的范围等。
PDU会话数相关的分析结果可以是PDU会话数的范围，最大PDU会话数，最大PDU会话数的范围，去激活PDU会话数的范围，去激活PDU会话数的最大值，激活态PDU会话数的范围，激活态PDU会话数的最大值等。
在本公开实施例中，NWDAF可通过一定的算法根据切片的信息确定所述切片内UE数相关的分析结果或者切片内PDU会话数相关的分析结果。具体的算法可根据实际需要进行选择。
在本公开实施例中，为提高控制的准确性，在步骤101之后，所述方法还可包括：根据所述切片的信息，获得区域信息。其中，所述区域信息包括AMF集合或切片覆盖区的信息。
在本公开实施例中，NWDAF可通过以下任一方式确定所述切片内UE数相关的分析结果或者切片内PDU会话数相关的分析结果。
方式一、NWDAF可获取所述UE的信息，然后，根据所述切片的速率、所述UE的信息以及切片在不同区域的切片速率统计信息，确定所述切片内UE数相关的分析结果或者切片内PDU会话数相关的分析结果。
其中，所述UE的信息包括所述UE的业务行为、所述UE的签约信息和所述UE的能力中的至少一项。
例如，NWDAF可通过对UE的业务行为，UE的签约信息，UE能力，切片在不同区域的数据速率的历史统计等进行综合分析，得到确定所述切片内UE数相关的分析结果或者切片内PDU会话数相关的分析结果。其中，UE能力可以是UE的优先级，UE的移动性管理能力，UE的会话管理能力等。
方式二、NWDAF按照一定的时间间隔从目标网元获取第一信息。然后，NWDAF根据所述第一信息，获得所述目标网元内的第一变化趋势，并根据所述切片的速率以及所述第一变化趋势，获得UE数相关的分析结果和PDU会话数相关的分析结果中的至少一项。其中，所述时间间隔可根据需要设置。
其中，所述第一信息为所述时间间隔内的平均切片速率或者峰值切片速率，所述第一变化趋势为速率变化趋势；或者，所述第一信息为所述时间间隔内的平均UE数或者峰值UE数，所述第一变化趋势为UE数变化趋势；或者，所述第一信息为所述时间间隔内的平均PDU会话数或者峰值PDU会话数，所述第一变化趋势为PDU会话数变化趋势。
例如，NWDAF可以请求AMF集合/切片覆盖区内的每个AMF每隔一段时间上报该时间段内的平均/峰值切片速率，NWDAF存储数据。NWDAF统计并分析历史数据，得到不同AMF集合/切片覆盖区产生的切片的速率随时间变化的趋势，并决定切片UE数或PDU会话数相关的分析记过，例如AMF集合/切片覆盖区的切片UE数或PDU会话数相关的分析结果，该分析结果可以是切片最大UE数的范围或最大PDU会话数的范围。例如，NWDAF根据上述趋势分析20:00-23:00之间不同AMF集合/切片覆盖区产生的切片速率，发现AMF集合1/切片覆盖区1在20:00-22:00产生的切片速率为10Mpbs，AMF集合2/切片覆盖区2在20:00-22:00产生的切片速率为5Mbps，则NWDAF决定的切片UE数相关的分析结果为AMF集合1/切片覆盖区1的最大UE数范围为1000至1100，或者最大PDU会话数的范围为2000至2100， AMF集合2/切片覆盖区2的最大UE数的范围为500至510，或者最大PDU会话数的范围为1000至1050。NWDAF决定的切片UE数或者PDU会话数的分析结果也可以是在20：00-22：00之间不同AMF集合/切片覆盖区的UE数变化趋势或PDU会话数变化趋势。NWDAF将切片UE数或PDU会话数的分析结果发送给配额配置功能(例如OAM，PCF,UDM，UDR等)或者AMF集合/切片覆盖区内的AMF。配额配置功能根据分析结果决定不同的AMF集合/切片覆盖区的切片的配额(例如切片UE数或PDU会话数或切片最大UE数或最大PDU会话数)，然后向不同的AMF集合/切片覆盖区内的AMF发送切片的配额。如果NWDAF直接将分析结果发送给AMF集合/切片覆盖区内的AMF，则该AMF根据分析决定本AMF集合/切片覆盖区的切片UE数或PDU会话数或切片最大UE数或最大PDU会话数。在该实施例中，NWDAF还可能向配置配置功能发送AMF集合/切片覆盖区的标识，切片标识。配额配置功能还可能向不同的AMF集合/切片覆盖区内的AMF发送切片标识。
例如，NWDAF还可请求AMF集合/切片覆盖区内的每个AMF每隔一段时间上报这段时间内的平均/峰值UE数或PDU会话数，NWDAF存储数据，统计并分析历史数据，决定切片的UE数或PDU会话数相关的分析结果，例如UE数或PDU会话数在特定时间段内变化的趋势，最大UE数或最大PDU会话数，最大UE的范围或最大PDU会话数的范围。例如，NWDAF根据上述趋势分析20:00-23:00之间不同AMF集合/切片覆盖区的UE数和PDU会话数，发现AMF集合1/切片覆盖区1在20:00-22:00服务的UE数为200，PDU会话数为300，AMF集合2/切片覆盖区2在20:00-22:00服务的UE数为50，PDU会话数为100，则NWDAF决定AMF集合1/切片覆盖区1的UE数相关的分析结果为最大UE数为210，最大PDU会话数为310，决定AMF集合2/切片覆盖区2的UE数相关的分析结果为最大UE数为60，最大PDU会话数为120。
例如，NWDAF可以请求NF(Network Function，网络功能)(如AMF，SMF，PCF，NSQ，NSSF，UDM，OAM等)每隔一段时间上报该时间段内的平均/峰值切片速率，NWDAF存储数据。NWDAF统计并分析历史数据，得到不同NF产生的切片的速率随时间变化的趋势，并决定切片的UE数和 PDU会话数相关的分析结果，例如切片的最大UE数的范围和最大PDU会话数的范围，并将切片的UE数和PDU会话数相关的分析结果发送给NF，该NF可以是配额配置功能(例如UDM，UDR，OAM等)也可以是统计UE数和PDU会话数的网络功能(例如PCF，SMF，AMF，NSSF等)。例如，NWDAF根据上述趋势分析20:00-23:00之间不同NF产生的切片速率，发现NF1在20:00-22:00产生的切片速率为10Mpbs，NF2在20:00-22:00产生的切片速率为5Mbps，则NWDAF决定切片的UE数和PDU会话数相关的分析结果，可以是NF1支持的最大UE数为1000，最大PDU会话数为2000，NF2支持的最大UE数为500，最大PDU会话数为1000。
例如，NWDAF还可以请求NF每隔一段时间上报这段时间内的平均UE数或PDU会话数，NWDAF存储历史数据，统计并分析历史数据，得到UE数或PDU会话数随时间变化的趋势，NWDAF根据该趋势决定切片的UE数或PDU会话数相关的分析记过，例如在不同时间点或时间段内NF可支持的切片的UE数或PDU会话数。例如，NWDAF根据上述趋势分析20:00-23:00之间不同NF的UE数和PDU会话数，发现NF1在20:00-22:00服务的UE数为200，PDU会话数为300，NF2在20:00-22:00服务的UE数为50，PDU会话数为100，则NWDAF向NF1发送的UE数的分析结果可以为切片标识和最大UE数为210，最大PDU会话数为310，向NF2发送的UE数的分析结果可以为切片标识和最大UE数为60，最大PDU会话数为120。

在以上实施例的基础上，NWDAF还可确定确定所述退避定时器相关的分析结果(如退避定时器时长)，并向网络功能发送所述退避定时器相关的分析结果。
具体的，NWDAF获取第一时间戳信息和第二时间戳信息，然后，NWDAF根据所述第一时间戳信息和所述第二时间戳信息，确定所述退避定时器相关 的分析结果；

例如，NWDAF还可以请求NF每隔一段时间上报这段时间内的平均UE数或PDU会话数，NWDAF存储历史数据，统计并分析历史数据，得到UE数或PDU会话数随时间变化的趋势，NWDAF根据该趋势决定切片的UE数和PDU会话数相关的分析结果，例如在不同时间点或时间段内NF可支持的切片的UE数或PDU会话数的范围。例如，NWDAF根据上述趋势分析20:00-23:00之间不同NF的UE数和PDU会话数，发现NF1在20:00-22:00服务的UE数为200，PDU会话数为300，NF2在20:00-22:00服务的UE数为50，PDU会话数为100，则NWDAF为NF1决定的UE数相关的分析结果可以为UE数的最大值为210，PDU会话数相关的分析结果可以为PDU会话数的最大值为310，NWDAF将分析结果发送给NF1。NWDAF为NF2决定的UE数相关的分析结果可以为UE数的最大值为为60，将PDU会话数相关的分析结果可以为PDU会话数的最大值120。
参见图5，图5本公开实施例提供的信息处理方法的流程图。在本公开实施例中，NF发现切片内的UE数达到NWDAF提供的切片可支持的UE数时，NF通过AMF overload机制控制切片内的UE数。NF可以是AMF，PCF，NSSF，NSQ，存储功能等。如图5所示，可包括如下过程：
501、AMF向NF订阅切片UE数达到最大值的事件或S-NSSAI overload(超负荷)事件。此步骤为可选步骤，如果NF是AMF，则不需要执行该步骤。
502、当NF发现切片的UE数已达到最大值，则NF向AMF发送通知，消息包括切片标识，切片UE数已达最大值或S-NSSAI overload。
503、AMF向RAN发送NGAP OVERLAOD START消息，消息包括切片标识。
504、当NF发现切片的UE数低于最大值，则NF向AMF发送通知，消息包括切片标识，切片UE数未达最大值或S-NSSAI overload停止。
505、AMF向RAN发送NGAP OVERLOAD STOP消息，消息包括切片标识。
在上述过程中，当AMF发现切片的UE数达到最大值时，如果AMF接收到的requested(请求的)NSSAI(Network Slice Selection Assistance Information，网络切片选择辅助信息)中包括该切片的S-NSSAI，则AMF根据本地存储的UE上下文中的UE优先级信息，将低优先级UE从切片中移除，即从低优先级UE的Allowed NSSAI(允许的NSSAI)中删除该S-NSSAI，然后AMF向低优先级UE发送UE配置更新消息，消息中包括更新后的Allowed NSSAI，然后向高优先级UE返回的Allowed NSSAI中包括该切片的S-NSSAI。AMF从UDM中获取的签约信息中包括UE优先级。NF可以是AMF，PCF，NSSF，NSQ，存储功能，配额配置功能等。具体过程如图6所示。
601、AMF向NF订阅切片UE数达到最大值的事件或S-NSSAI overload事件。此步骤为可选步骤，如果NF是AMF，则不需要执行该步骤。
602、当NF发现切片的UE数已达到最大值，则NF向AMF发送通知，消息包括切片标识，切片UE数已达最大值或S-NSSAI overload。
603、UE向AMF发送注册请求，消息中的requested NSSAI包括上述切片的S-NSSAI。
604、AMF发现UE1的优先级低于UE，或者UE1的优先级低于UE且UE1未建立到该切片的PDU会话，或者UE1的优先级低于UE且UE1建立到该切片的PDU会话的用户面连接均被去激活，AMF向UE1发送UE配置更新，消息中包括Allowed NSSAI(移除上述切片的S-NSSAI)和rejected S-NSSAI(上述切片的S-NSSAI)和拒绝原因(表明切片的UE数达到最大值)。
605、AMF向UE发送注册接受，消息中的Allowed NSSAI包括上述切片的S-NSSAI。
如果不存在符合步骤604中的判断条件的UE，则AMF不执行步骤604，在步骤605向UE返回注册拒绝消息，消息包括rejected S-NSSAI(上述切片 的S-NSSAI)和拒绝原因(表明切片的UE数达到最大值)。
当切片的UE数小于最大UE数时，例如部分UE不再使用该切片或NWDAF更新了最大UE数或减少退避定时器时长，NF向AMF/SMF发送通知，消息中包括切片标识，切片UE数未达最大值或S-NSSAI未拥塞。
参见图7，图7本公开实施例提供的信息处理方法的流程图。在本公开实施例中，NF发现切片内的PDU会话数达到NWDAF提供的切片可支持的PDU会话数时，NF通过NAS(Non-access stratum，非接入层)level congestion control(拥塞控制)机制控制切片内的PDU会话数。如图7所示，可包括如下过程：
701、AMF/SMF向NF订阅切片PDU会话数达到最大值的事件或S-NSSAI SM拥塞事件。此步骤为可选步骤，如果NF是AMF/SMF，则不需要执行该步骤。
702、当NF发现切片的PDU会话数已达到最大值，则NF向AMF/SMF发送通知，消息包括切片标识，切片PDU会话数已达最大值或S-NSSAI SM拥塞。AMF/SMF启动S-NSSAI SM拥塞控制机制。
当切片的PDU会话数小于最大PDU会话数时，例如切片内的部分PDU会话被释放或NWDAF更新了最大PDU会话数或减少退避定时器时长，NF向AMF/SMF发送通知，消息中包括切片标识，切片PDU会话数未达最大值或S-NSSAI SM未拥塞。
在本公开实施例中，NWDAF决定切片UE数相关的分析结果、PDU会话数相关的分析结果以及退避定时器相关的分析结果。
其中，NWDAF通过对UE的业务行为、UE的签约信息、UE能力、切片在不同区域的数据速率的历史统计等综合分析，获得切片的UE数和PDU会话数。其中，UE能力可以是UE的优先级、UE的移动性管理能力、UE的会话管理能力等。
为了决定退避定时器相关的分析结果，NWDAF从统计UE数或PDU会话数的NF获取区域、历史UE数或PDU会话数(例如NWDAF要求统计NF每隔一段时间就上报一次平均/峰值UE数或PDU会话数)和时间戳(例如UE数或PDU会话数达到最大值的时间、UE数或PDU会话数在达到最大值 后首次低于最大值的时间)，NWDAF分析该区域内UE数或PDU会话数的变化趋势。
NWDAF根据变化趋势和时间戳决定退避定时器相关的分析结果，例如时长，或将上述变化趋势和时间戳信息发生给统计UE数或PDU会话数的NF，由NF根据该趋势和时间戳计算出退避定时器时长，NF将退避定时器时长发送给AMF/SMF。
NWDAF可以请求NF每隔一段时间上报该时间段内的平均/峰值切片速率，速率达到最大速率的时间戳，达到最大速率之后首次低于最大速率的时间戳，NWDAF存储数据。
NWDAF统计并分析历史数据，获得不同NF产生的切片的速率随时间变化的趋势，并决定速率达到最大值时的退避定时器相关的分析结果。例如NWDAF根据上述趋势分析20:00-20:30之间NF1的切片速率会达到最大值，可能会产生10分钟的拥塞，NWDAF决定退避定时器相关的分析结果，例如退避定时器时长为10分钟，并在20:00向NF1提供退避定时器相关的分析结果。当NF1发现拥塞时，NF1使用该退避定时器时长，并通知给NWDAF。NWDAF请求OAM监测5分钟之内的NF1产生的切片流量，如果切片流量有所下降，则NWDAF决定退避定时器相关的分析结果，例如退避定时器时长为5分钟，并发送给NF1；如果切片流量持续上升，则NWDAF决定退避定时器相关的分析结果，例如退避定时器的时长为15分钟，并发送给NF1。
NWDAF还可以请求NF每隔一段时间上报这段时间内的平均UE数或PDU会话数，UE数或PDU会话数达到最大值的时间戳，达到最大值之后首次低于最大值的时间戳，NWDAF存储历史数据，统计并分析历史数据，UE数或PDU会话数随时间变化的趋势。
NWDAF根据该趋势决定在不同时间点或时间段内切片的UE数或PDU会话数相关的分析结果，并决定UE数或PDU会话数达到最大值时的退避定时器相关的分析结果。例如NWDAF根据上述趋势分析20:00-20:30之间决定切片UE数或PDU会话数相关的分析结果以及退避定时器相关的分析结果，例如切片UE数或PDU会话数达到最大值的时间为20：30，可能会产生10分钟的拥塞，NWDAF在20:00向NF1提供的退避定时器相关的分析结果为 时长为10分钟。NF根据NWDAF的分析结果，决定退避定时器的时长并将其提供给AMF或SMF。该NF可以是UDM/UDR，OAM，O&M或NRF。
在本公开的一个实施例中，NWDAF将UE数和PDU会话数的分析结果发送给UDM/UDR，OAM，O&M或NRF。UDM/UDR，OAM，O&M或NRF根据分析结果，在不同的第二网元之间分配PDU会话数和UE数，例如最大PDU会话数，最大UE数，然后将分配结果通知给第二网元。NWDAF将退避定时器时长相关的分析结果或拥塞控制相关的分析结果发送给UDM/UDR，OAM，O&M或NRF，这些网元根据分析结果，决定退避定时器时长或决定向第二网元发送拥塞控制指示，然后向第二目标网元发送退避定时器时长或拥塞控制指示。
第二网元可以是PCF，AMF，SMF，NSSF，NSQ和NRF。
退避定时器相关的分析结果是启动定时器的时间范围，退避定时器的时长范围，拥塞结束的时间范围等。拥塞控制相关的分析结果可以是拥塞控制指示，拥塞的时间范围，拥塞结束的时间范围等。
