Description

移动网络优化处理方法、设备及系统 技术领域
本申请实施例涉及通信技术，尤其涉及一种移动网络优化处理方法、设备及系统。
背景技术
随着移动通信技术的不断发展，为了能够兼顾用户体验和网络的资源使用效率，移动网络优化变得越来越重要。移动网络优化主要是指提高无线电资源的利用率，例如，控制用于UE(user equipment，用户装置)和无线接入网(Radio Access Network，RAN)的接入节点之间的数据传输的空中接口资源的分配和信令，同时减小UE中的功耗。
由于UE具有所处位置变化，功率受限等特性，因此在现有技术中，可以通过控制UE的状态转换实现网络优化。例如，将处于连接态的UE在无数据传输时释放空口连接，并在基站处删除其上下文，使UE处于空闲态。当处于空闲态的UE需要传输数据时，再触发业务请求过程，请求网络侧恢复其空口连接。这样不仅可以避免空中接口资源的无效占用，提高无线电资源的利用率，而且处于空闲态的UE相较连接态的UE可以消耗更少的功率，达到减小UE中的功耗的目的。
然而，现有的触发UE的连接态转空闲态的条件之一为：UE在10秒～30秒内无数据传输(具体时长根据运营商设定)，如果UE确实无需传输数据，那么UE在此段时间处于连接态并无意义，可见依然存在功率浪费。另一方面，当处于空闲态的UE需要进行数据传输时，需要转换为连接态时，这伴随着网络侧触发的业务请求过程。UE需等待演进节点B(Evolved NodeB，eNB)和核心网侧(MME、S-GW等)建立连接，以及空口连接(UE和eNB)建立完毕后，才能进行数据传输，这样会导致较大的时延；同时，由于UE的移动特性，可能会移出原小区的覆盖范围，这样就使得网络侧需要在跟踪区列表(Tracking Area List，TA List)中对所有演进节点B(Evolved NodeB，eNB)进行寻呼，造成额外的寻呼信令消耗，从而导致信令资源的浪费。

(5)归属用户服务器(Home Subscriber Server，HSS)：用于存储用户签约信息的服务器，主要负责管理用户的签约数据及移动用户的位置信息。
(6)演进的通用陆地无线接入网络(Evolved Universal Terrestrial Radio Access Network，E-UTRAN)：包含演进节点B(Evolved NodeB，eNB)，为终端的接入提供无线资源，可以提供更高的上下行速率，更低的传输延迟和更加可靠的无线传输。
(7)服务网关(Serving GateWay，S-GW)：是一个用户面实体，负责用户面数据路由处理，终结处于空闲态的UE下行数据；管理和存储UE的系统结构演进(System Architecture Evolution，SAE)承载上下文，是3GPP系统内部用户面的锚点。
(8)分组数据网网关(Packet Data Network GateWay，P-GW)：负责UE接入分组数据网(Packet Data Network，PDN)的网关，分配用户IP地址，同时是3GPP和非3GPP接入系统的移动性锚点。

(16)数据网络(Data Network，DN)：用于传输数据的网络，例如Internet网络等。
可以理解的是，在一些可能的设计中，系统架构中的逻辑功能单元还可能包括：
网络功能(Network Function，NF)实体：对网络功能实体的一种更为概括的描述，例如，AMF实体，SMF实体，策略与计费功能(Policy and Charging Function，PCF)实体等网络功能实体均可以被称为NF。
控制面功能(Control Plane Function，CPF)实体：主要进行UE的鉴权、加密以及位置注册等接入控制和移动性管理功能(例如AMF的功能)，以及用户面传输路径的建立、释放和更改等会话管理功能(例如SMF的功能)。从方便理解的角度，可以认为CPF是包括AMF实体，SMF实体，PCF实体等网元的集合。
应用功能(Application Function，AF)实体：与3GPP核心网网元交互，并提供诸如影响路由决策、网络能力开放的接入、与策略框架(policy framework)进行交互以提供策 略控制等功能。
NWDA功能实体中收集的数据可以被应用于通信网络中。NWDA功能实体中的数据会通过相关的接口(在图1所示应用场景中为INWDAMME接口，在图2所示应用场景中为Nnwda接口)，将数据发送到MME或AMF实体与SMF实体处，用于进行网络的相关控制与优化。应理解，在图1中，NWDA功能实体与MME之间连接的INWDAMME接口为NWDA功能实体与MME之间的连接接口的一种表示，在标准中暂时未定义此接口与网元。同样应理解，图2是从服务化接口的角度描述网络架构，从点对点的角度描述网络架构的情形与此类似，在此不再赘述。
对于NWDA功能实体中数据的来源可以包括以下几种：
第一，可以是来源于从UE直接上报的数据，例如UE的GPS位置信息。其接口在图中未示出，在实际实现中可能是以隧道的方式接入到NWDA功能实体中，例如在图1所示应用场景中，可以以UE-eNB-MME-NWDA的顺序建立隧道；在图2所示应用场景中，可以以UE-(R)AN-AMF-NWDA的方式建立隧道。
第二，可以是来源于(R)AN侧的信息(同样可以经隧道发送)，例如UE所处小区的位置信息。
第三，可以是来源于网络中的其他网元，可能是应用功能(AF)实体上报的信息，也可能是网络功能(NF)实体上报的信息。例如图1所示应用场景中的MME，可以向INWDAMME接口发送信息，告知存储在MME中的信息，这些信息可以是MME存储的UE连接管理信息(包括空闲态还是连接态等)；再例如图2所示应用场景中的AMF实体、SMF实体和PCF实体等，通过相应接口向NWDA功能实体发送数据。
应理解，NWDA功能实体接收数据的具体方式在标准中尚未定义，上述描述仅为一种可能性。
值得注意的是，由于5G结构并未确定，因此本申请实施例所述架构仅作为一个示例，以便于描述本申请所提供的方案。执行移动性管理和会话管理的实体也可以放到其他的网元处。因此上述的应用场景架构并不用于限制本申请。为了便于理解，在下面的实施例描述中，可以使用AMF表示“执行移动性管理的功能”，SMF表示“执行会话管理的功能”。
本申请中的UE，也可以为其它任何终端装置。
下面以具体的实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图3为本申请实施例提供的一种移动网络优化处理方法流程示意图，如图3所示，本实施例提供的移动网络优化处理方法，包括：
S301，NWDA功能实体获取第一信息；
其中，在具体实施中，第一信息可包括UE的位置信息、UE的运动轨迹信息，UE位置历史统计信息和UE的业务信息中的一种或者多种，不排除是这几种信息以外的某种信息，例如通过大数据分析得到的某种信息。值得说明的是在本实施例中业务信息可以指的是业务数据发送结束信息。
例如，第一信息包括UE的位置信息、UE的运动轨迹、UE的业务信息等信息中的一种或多种。UE的位置信息例如可以包括全球定位系统(Global Positioning System，GPS) 信息、小区标识信息等中的至少一种。UE的运动轨迹例如可以包括UE的运动速度、UE的运动方向等中的至少一种。UE的业务信息例如可以包括UE的历史业务信息、应用特征信息等中的至少一种。示例性的，UE可以通过加速度传感器和陀螺仪传感器就可以准确地获得UE的运动速度和运动方向，通过UE中的GPS传感器就可以获得UE当前所在的地理位置信息，通过UE中的加速度传感器所获取到的UE的加速度信息，等等。
NWDA功能实体可以接收UE、AF实体、AN和NF实体其中至少之一定期地或由事件触发地，向NWDA功能实体上报的第一信息。应当理解，当NWDA功能实体同时从多个网元设备上收集到第一信息时，可以根据当前业务处理需要，以某一个网元设备上报的信息为依据确定对UE进行优化处理的信息，而忽略其他网元设备上报的信息，或者是综合考虑多个网元设备上报的信息，本申请实施例对此不做具体限定。
例如，UE会定期或由事件触发地，向NWDA功能实体上报UE的相关信息，这些信息可以包含：UE的位置信息，UE的应用信息等。
例如，AF实体会定期或由事件触发地，向NWDA功能实体发送UE的相关信息的通知消息，消息包含UE的标识信息，以及UE应用信息。
例如，NF实体会定期或由事件触发地，收集UE的相关信息，这些信息包含：UE的位置，运动轨迹等。如在图1所示场景下，在用户定期的跟踪区更新(Tracking Area Update，TAU)过程中，MME可以获取用户的E-UTRAN小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)信息，这属于定期触发的过程。当用户移出原先TA List的范围时，会触发由于移动引发的TAU过程，MME同样可以据此获取用户的ECGI信息，这属于事件触发的过程。NF实体会定期或由事件触发地，将UE的相关信息向NWDA功能实体进行上报。对于事件触发而言，以下列举两种方式：NF实体可能会以透传的方式将收集的信息直接转发至NWDA功能实体；另外，NF实体会在接收到NWDA功能实体发送的查询信息后，向NWDA功能实体返回UE的相关信息。
例如，(R)AN设备(例如eNB)会定期或由事件触发地，收集UE的相关信息。如在图1所示场景下，在用户定期的TAU过程中，基站可以获取用户的ECGI信息，这属于定期触发的过程。当用户移出原先TA List的范围时，会触发由于移动引发的TAU过程，基站同样可以据此获取用户的ECGI信息，这属于事件触发的过程。(R)AN设备会定期或由事件触发地，将UE的相关信息向NWDA功能实体进行上报。对于事件触发而言，(R)AN设备可能会以透传的方式将收集的信息直接转发至NWDA功能实体；另外，(R)AN设备会在接收到NWDA功能实体发送的查询信息后，向NWDA功能实体返回UE信息。
S302，NWDA功能实体根据第一信息确定第二信息；
其中，在具体实施中，第二信息可以包括UE的标识。此外，可包含对UE进行优化处理的时间信息，例如UE在多长时间后进入空闲态/连接态，而非立即进行状态转换，或者引起UE状态变化的业务建立时间，或者引起UE状态变化的业务结束时间，等等；或者第二信息可包含UE进行状态转换时所处的地理位置信息，例如UE在移动至某个位置时适合进行状态转换；或者第二信息可能包含对所述UE进行优化处理的指示信息，例如指示UE进入空闲态/连接态，或者引起UE状态变化的业务建立指示和引起UE状态变化的业务结束指示，等等。
换言之，第二信息可包括UE的位置信息、对UE进行优化处理的时间信息和对UE 进行优化处理的指示信息中的一种或多种。其中UE的位置信息可能是UE在预设时间点或时间段的位置信息，可以理解的是，该预设时间点可以是当前时刻，也可以是之后的时刻，该预设时间段可以是包含当前时刻的时间段，也可以是之后的时间段。值得一提的是，该预设时间点/时间段例如可以是NWDA通过第一信息分析得到的业务开始或结束的时间点/时间段进行设定。
例如，对于处于连接态的UE，NWDA功能实体基于收集的第一信息，决策UE释放资源的时机。例如，判断UE是否应变为空闲态，具体方法可以是，根据UE的移动轨迹，判断UE将会处于需要变为空闲态的时间和\或地点。决策获取的第二信息可包含多久后UE会释放资源变为空闲态，例如，UE在多长时间后变为空闲，而非立即会变为空闲。
例如，对于处于空闲态的UE，NWDA功能实体基于收集的第一信息，决策为UE分配资源的时间与地点。例如，UE转换为连接态的时间和/或地点信息，或者是UE建立会话的时间和/或地点信息，或者是UE建立承载或QoS流的时间。
示例性的，当第一信息包括UE的位置信息和运动轨迹信息，所述NWDA功能实体根据所述第一信息确定所述第二信息，包括：所述NWDA功能实体根据所述UE的位置信息和运动轨迹信息确定所述UE在预设时间点或时间段的位置信息。
示例性的，当第一信息包括所述UE的业务信息，所述NWDA功能实体根据所述第一信息确定所述第二信息，包括：所述NWDA功能实体根据所述UE的业务信息确定对所述UE进行优化处理的时间信息。
S303，NWDA功能实体向CPF实体发送携带第二信息的第一消息；
具体的，第一消息用于告知CPF实体可以根据第二信息对UE进行优化处理。该第一消息例如可以是资源释放请求消息或资源分配请求消息等。
例如，对于处于连接态的UE，NWDA功能实体向控制面相关的功能实体(MME、AMF实体、SMF实体等)发送UE的资源释放请求消息。资源释放请求消息可包括待释放资源的标识(ID)信息(标识需要释放何种资源)，UE的位置信息以及UE的标识信息。标识需要释放何种资源的标识信息为UE的状态转换标识，UE的位置信息为ECGI，UE的标识信息为UE的临时标识信息或永久标识信息；当需要释放资源的粒度为会话时，待释放资源的ID为分组数据单元(Packet Data Unit，PDU)会话(Session)ID，标识需要释放何种资源的标识信息为指示释放(或去激活)PDU Session ID的标识信息，UE的位置信息为ECGI，UE的标识信息为UE的临时标识信息或永久标识信息。
例如，对于处于空闲态的UE，NWDA功能实体向控制面相关的功能实体发送UE资源分配请求消息。资源分配请求消息包括UE的标识信息，以及UE建立资源的具体信息。具体地，当需要将UE恢复为连接态时，UE建立资源的具体信息为UE由空闲态转换为连接态的标识信息，控制面相关的功能实体为MME或AMF；当需要为UE建立新会话时，UE建立资源的具体信息为UE建立新会话的标识信息以及建立会话所需其他信息(例如，接入点名称(Access Point Name，APN)或数据网络名称(Data Network Name，DNN)等信息)，控制面相关的功能的实体为MME或SMF；当需要为UE建立新的承载或QoS流时，UE建立资源的具体信息为UE建立新的承载或QoS流的标识信息(例如，承载的QoS信息等)，控制面相关的功能实体为MME或SMF。
S304，CPF实体根据第一消息对UE进行优化处理。
例如，对于处于连接态的UE，CPF实体根据第一请求消息中携带的第二信息进行相关资源的释放过程。释放的粒度可以是：改变UE的状态(由连接态变为空闲态)；释放UE的PDU Session，属于粗粒度的；释放UE的QoS流(flow)，属于细粒度的。
例如，对于处于空闲态的UE，CPF实体根据第一请求消息中携带的第二信息进行连接建立操作。例如，当MME/AMF实体接收到UE由空闲态转换为连接态的标识信息时，进行对UE的寻呼操作，或者当MME/SMF实体接收到为UE建立新会话的标识信息时，进行会话的建立过程。特别地，第一请求消息中携带的第二信息可以包含UE的具体位置信息，用于对UE的寻呼范围进行优化。
本实施例提供的移动网络优化处理方法，通过负责网络数据分析功能的网元(NWDA)基于UE的应用层信息(即第一信息)分析得到用于对UE进行优化处理的信息，并告知CPF实体，如负责移动性管理的网元或会话管理的网元，以使CPF实体根据用于对UE进行优化处理的信息对UE进行优化处理。
本实施例提供的移动网络优化处理方法，通过应用层和通信层联合优化的方法，基于应用层提供的信息，指导UE进行合理的状态转换，从而可以解决或至少部分地解决现有技术中控制UE的状态转换过程中存在的问题。具体可以体现在以下至少一个方面：
1)在UE需要进行数据传输之前，根据UE的应用层信息，预先将处于空闲态的UE转换为连接态，无需等待由网络侧触发的业务请求过程，从而减小时延；
2)根据UE的应用层信息，直接快速将UE转换为空闲态，而无需等待网络设定的10～30秒的等待时间，从而减小UE的功耗，同时可以避免空中接口资源的无效占用，提高无线电资源的利用率；
3)处于空闲态的UE转换为连接态时，根据UE的应用层信息可以预测在寻呼UE时UE所处的位置信息，缩小寻呼UE的范围，从而减小在寻呼时的信令开销。
为让本申请的技术方案和有益效果能更明显易懂，下面将通过一些具体实施例并配合附图对本申请的技术方案作进一步详细说明。显然，这些实施例是用来说明，而并非用来限制本申请。
图4为本申请实施例提供的一种移动网络优化处理方法流程示意图，本实施例以图1所示的应用场景为例，对UE转换为空闲态的过程进行说明。对于相同或相似的步骤，以及涉及的名词可以参照上述图3所述实施例的描述，本实施例对此不再赘述。
如图4所示，本实施例提供的对UE转换为空闲态的过程，包括：
S401，NWDA功能实体获取第一信息；
可选的，NWDA功能实体可以接收UE、AN、AF实体和NF实体其中至少之一定期地或由事件触发地，向NWDA功能实体上报的第一信息。其中，在具体实施中，第一信息可能包括UE的当前位置信息、UE的运动轨迹信息，UE位置历史统计信息和UE的业务信息中的一种或者多种，不排除是这几种信息以外的某种信息，例如通过大数据分析得到的某种信息。值得说明的是在本实施例中业务信息可以指的是业务数据发送结束信息。
S402，NWDA功能实体根据第一信息确定第二信息；
S403，NWDA功能实体向MME发送携带第二信息的第一消息；
例如，NWDA功能实体基于获取的第一信息，预测UE处于空闲态的时机，并根据预 测结果向MME发送携带该预测结果的第一消息。例如，NWDA可以根据历史业务信息进行预测，或根据应用消息的提示等进行预测。预测结果可能包含UE转换为空闲态的时间，例如UE在多长时间后变为空闲态，也可能是立即需要变为空闲态；或者预测结果可能包含UE转换为空闲态时所处的地理位置信息，例如UE在移动至某个位置时适合变为空闲态；或者两者组合。
示例性的，NWDA功能实体预测UE适合立即转为空闲态，则第二信息可以包括UE进入空闲态的指示信息或者是业务结束的指示信息。
示例性的，NWDA功能实体预测UE适合在一段时间后变为空闲态，则第二信息可以包括对UE进行优化处理的时间信息，还可以包括UE进入空闲态的指示信息或者是业务结束的指示信息。
S404，MME根据第一消息触发UE的连接释放过程。
值得一提的是，关于对所述UE进行优化处理的时间信息如何反映到网元的处理中，由网元实现决定。例如，由NWDA功能实体基于第一信息分析预测得到UE处于空闲态的时间，可以在NWDA功能实体处设立定时器，等待超时后再向MME发送UE的资源释放请求消息。可以理解的是，如果第二信息包括将UE转换为空闲态或者业务结束的时间信息，可以在MME处设立定时器，等待超时后MME触发UE的连接释放过程。
需要说明的是，本实施例提供的对UE转换为空闲态的过程，可能在UE处于连接态时进行。
图5为本申请实施例提供的一种移动网络优化处理方法流程示意图，本实施例以图2所示的应用场景为例，对UE转换为空闲态的过程进行说明。对于相同或相似的步骤，以及涉及的名词可以参照上述图3所述实施例的描述，本实施例对此不再赘述。
如图5所示，本实施例提供的对UE转换为空闲态的过程，包括：
S501，NWDA功能实体获取第一信息；
S502，NWDA功能实体根据第一信息确定第二信息；
S503，NWDA功能实体向AMF实体发送携带第二信息的第一消息；
S504，AMF实体根据第一消息触发会话去激活流程。
值得一提的是，在具体实施过程中，S503和S504可能存在如下替代操作：
S503a：NWDA功能实体向SMF实体发送携带第二信息的第一消息；
S504a：SMF实体根据第一消息触发会话去激活流程。
需要说明的是，会话去激活流程是指SMF实体告知(R)AN删除会话上下文，以及SMF实体告知UPF实体删除会话连接标识信息的过程。
选择上述两种操作中的哪一种，取决于连接的释放方式，在实现中可以选择任何一种。
同样可以理解的是，本实施例提供的对UE转换为空闲态的过程，可能在UE处于连接态时进行。
需要说明的是，同前所述，由于5G结构并未确定，在本实施例中仅用AMF实体和SMF实体进行示例性说明。在标准完成阶段，执行移动管理的实体可能放到其他的网元处。因此保护范围不限于针对AMF实体和SMF实体的操作。
上述实施例提供的对UE转换为空闲态的过程，通过应用层和通信层联合优化的方法， 基于应用层提供的信息，指导UE进行合理的状态转换，根据UE的应用层信息，直接快速将UE转换为空闲态，或者是提前将UE的状态由连接态变为空闲态，而无需等待网络设定的10～30秒的等待时间，从而减小UE的功耗，同时可以避免空中接口资源的无效占用，提高无线电资源的利用率。
图6为本申请实施例提供的一种移动网络优化处理方法流程示意图，本实施例以图1所示的应用场景为例，对UE转换为连接态的过程进行说明。对于相同或相似的步骤，以及涉及的名词可以参照上述图3所述实施例的描述，本实施例对此不再赘述。
如图6所示，本实施例提供的对UE转换为连接态的过程，包括：
S601，NWDA功能实体获取第一信息；
S602，NWDA功能实体根据第一信息确定第二信息；
S603，NWDA功能实体向MME发送携带第二信息的第一消息；
例如，NWDA功能实体基于获取的第一信息，预测UE处于连接态的时机，并根据预测结果向MME发送携带所述预测结果的第一消息。预测结果可包含UE需要转换为连接态的时间，例如UE在多长时间后变为连接态，也可能是需要立即变为连接态；或者预测结果可能包含UE需要转换为连接态时所处的地理位置信息，例如UE在移动至某个位置时需要变为连接态；或者两者组合。
示例性的，NWDA功能实体预测UE适合立即转为连接态，则第二信息可以包括UE当前的位置信息。可选的，第二信息还可以包括UE进入连接态的指示信息或业务开始指示信息。UE进入连接态的指示信息或业务开始指示信息是可选的原因在于，MME可以根据由消息名称判断第一消息的目的是请求将UE转换为连接态(隐式说明状态需要转换)，也可以通过连接态指示判断第一消息的目的是请求将UE转换为连接态(显示说明状态需要转换)。
示例性的，NWDA功能实体预测UE适合在一段时间后变为连接态，则第二信息可以包括UE进入连接态的指示信息或者暗示UE需要进入连接态的业务开始指示信息。可选地，第二信息进一步包括业务发生的位置信息和/或者时间信息。
示例性的，NWDA功能实体预测到UE需要转换为连接态的位置信息。值得一提的是，位置信息可能是一种数据结构。换言之，位置信息可能是空间维度的，即包含具体的地理位置，也可能是时空维度的，即包含具体的地理位置以及与此地理位置相关联的时间。
S604，MME根据第一消息确定UE需要转入连接态，并向eNB发送寻呼消息，以请求建立UE的连接。
S605，eNB寻呼UE。
可以理解的是，如果UE已经是连接态，则结束流程。
同样可以理解的是，关于对UE进行优化处理的时间信息如何反映到网元的处理中，由网元实现决定。例如，NWDA功能实体基于第一信息分析预测得到UE处于连接态的时间，可以在NWDA功能实体处设立定时器，等待超时后再向MME发送UE的资源分配请求消息。如果第二信息包括UE处于连接态的时间，可以在MME处设立定时器，等待超时后MME向eNB发送寻呼消息。UE在接收到寻呼消息之后，完成转换为连接态的过程。
例如，S604在具体实施过程中可能存在两种操作：
1)第二信息包括对所述UE进行优化处理的时间信息，而没有对所述UE进行优化处理的位置信息，此时只能按照正常的寻呼过程，即：MME寻呼TA List中所有的eNB，之后再由eNB寻呼UE。这样可以提前根据UE的应用层信息，预先将处于空闲态的UE转换为连接态，无需等待由网络侧触发的业务请求过程，从而减小时延。
2)第二信息包括对所述UE进行优化处理的位置信息，此时，MME可以根据该位置信息向该位置信息对应的eNB发送寻呼消息。这样可以根据UE的应用层信息，预测在寻呼UE时UE所处的位置信息，缩小寻呼UE的范围，从而减小在寻呼时的信令开销。
值得一提的是，MME在接收到NWDA功能实体发送的第一消息时，如果第二信息只包括UE的位置信息(位置信息可能是空间维度的，即包含具体的地理位置，也可能是时空维度的，即包含具体的地理位置以及与此地理位置相关联的时间)，MME可以立即向位置信息对应的E-UTRAN发送寻呼消息，也可以对第二信息进行存储，等待网络侧触发的业务请求而需要寻呼UE时，根据UE的位置信息对UE进行寻呼。
可以理解的是，本实施例提供的对UE转换为连接态的过程，可能在UE处于空闲态时进行；也可能由AF实体根据业务需要的触发执行UE转换为连接态的过程，此时UE处于何种状态并不重要。也就是说，网络中可以没有UE的状态信息，而依然向UE发送转换为连接态的指示(例如业务触发指示)。
可选的，在S601之前还可能包括以下步骤：
步骤1：MME检测到UE处于空闲态时，向NWDA功能实体发送第一通知消息；
例如MME可以通过S1连接释放过程中的控制面消息检测到UE处于空闲态，并向NWDA功能实体发送第一通知消息，以告知UE处于空闲态。第一通知消息中包含UE的标识，还可能包含UE处于空闲态标识。
步骤2：NWDA功能实体接收到MME发送的第一通知消息后获取第一信息，进而开始预测UE下一次恢复连接态的位置信息与时间信息等。
可以理解的是，上述步骤1和步骤2与S601可以不存在时序上的关系，S601可能在步骤1和步骤2之前，也有可能步骤1和步骤2在S601之前，也有可能两者运行时会有交集(有可能同时进行部分步骤)。
图7为本申请实施例提供的一种移动网络优化处理方法流程示意图，本实施例以图2所示的应用场景为例，对UE转换为连接态的过程进行说明。对于相同或相似的步骤，以及涉及的名词可以参照上述图3所述实施例的描述，本实施例对此不再赘述。
如图7所示，本实施例提供的对UE转换为连接态的过程，包括：
S701，NWDA功能实体获取第一信息；
S702，NWDA功能实体根据第一信息确定第二信息；
S703，NWDA功能实体向AMF实体发送携带第二信息的第一消息；
S704，AMF实体确定UE需要进入连接态并根据第一消息执行相关处理流程。
例如，AMF实体可以根据第二信息向(R)AN发送寻呼消息，以请求建立UE的连接，或者AMF实体根据第二信息触发对相关的会话激活流程。如果UE当前处于非接入层(Non Access Stratum，NAS)空闲状态，那么将转入步骤705。
S705，(R)AN寻呼UE。
值得一提的是，在具体实施过程中，如果UE当前处于NAS连接态状态，但UE的某个会话没有被激活时，S703～S705可能存在如下替代操作：
S703a，NWDA功能实体向SMF实体发送携带第二信息的第一消息；
S704a，SMF实体确定UE需要激活会话，并根据第一消息执行相关处理流程。
例如，SMF实体可以根据第二信息按照现有方式触发会话激活流程。
需要说明的是，S704在具体实施过程中可能存在两种操作：
1)第二信息包括对所述UE进行优化处理的时间信息，而没有对所述UE进行优化处理的位置信息，此时只能按照正常的寻呼过程，即：AMF实体寻呼TA List中所有的(R)AN，之后再由(R)AN寻呼UE。这样可以提前根据UE的应用层信息，预先将处于空闲态的UE转换为连接态，无需等待由网络侧触发的业务请求过程，从而减小时延。
2)第二信息包括对所述UE进行优化处理的位置信息，此时，AMF实体可以根据第二信息中的位置信息向该位置信息对应的(R)AN发送寻呼消息。这样可以根据UE的应用层信息，预测在寻呼UE时UE所处的位置信息，缩小寻呼UE的范围，从而减小在寻呼时的信令开销。
其中，AMF实体在接收到NWDA功能实体发送的携带第二信息的第一消息时，如果第二信息只包括UE的位置信息(位置信息可能是空间维度的，即包含具体的地理位置，也可能是时空维度的，即包含具体的地理位置以及与此地理位置相关联的时间)，AMF实体可以立即向位置信息对应的(R)AN发送寻呼消息，也可以对第二信息进行存储，等待网络侧触发的业务请求而需要寻呼UE时，根据UE的位置信息对UE进行寻呼。
同样可以理解的是，本实施例提供的对UE转换为连接态的过程，可能在UE处于空闲态时进行；也可能由AF实体定期的触发执行UE转换为连接态的过程，此时UE处于何种状态并不重要。也就是说，网络中可以没有UE的状态信息，而依然向UE发送UE需要处于连接态的指示(例如业务触发指示)。
可选的，在S701之前还可能包括以下步骤：
步骤1：AMF实体检测到UE处于空闲态时，向NWDA功能实体发送第一通知消息；
例如AMF实体可以通过UE的连接释放过程中的控制面消息检测到UE处于空闲态，并向NWDA功能实体发送第一通知消息，以告知UE处于空闲态。第一通知消息中包含UE的标识，还可能包含UE处于空闲态标识。
步骤2：NWDA功能实体接收到AMF实体发送的第一通知消息后获取第一信息，进而开始预测UE下一次恢复连接态的位置信息与时间信息等；
同样可以理解的是，上述步骤1和步骤2与S701也可以不存在时序上的关系，S701可能在步骤1和步骤2之前，也有可能步骤1和步骤2在S701之前，也有可能两者运行时会有交集(有可能同时进行部分步骤)。
上述实施例提供的对UE转换为连接态的过程，通过应用层和通信层联合优化的方法，基于应用层提供的信息，指导UE进行合理的状态转换。一方面，可以实现根据UE的应用层信息，预先将处于空闲态的UE转换为连接态，无需等待由网络侧触发的业务请求过程，从而减小时延；另一方面，在将处于空闲态的UE转换为连接态时，根据UE的应用层信息可以预测在寻呼UE时UE所处的位置信息，缩小寻呼UE的范围，从而减小在寻 呼时的信令开销。
基于与上述方法实施例相同的思想，本申请实施例还提供多种功能实体。该多种功能实体可以通过软件、硬件或者软硬结合的方式实现，可以用于实现上述方法实施例提供的优化处理方法。其中装置部分与上述方法对应，对应内容和技术效果相同，在此不再赘述。
