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，控制用于用户设备(User Equipment，UE)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。

在本申请的部分实施例中将以图1所示第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)系统为例对本申请的应用场景做示意性说明。图1为本申请实施例提供的一种移动网络优化处理方法应用场景示意图。在本申请的部分实施例中将以图2所示3GPP系统为例对本申请的应用场景做示意性说明。图2为本申请实施例提供的另一种移动网络优化处理方法应用场景示意图。如图1和图2所示，该系统架构中的逻辑功能单元主要包括：
(1)业务能力服务器/应用服务器(Service Capability Server/Application Server，SCS/AS)：用于相关的业务逻辑的实现，向用户提供应用层的信息。
(2)业务能力开放功能(Service Capability Exposure Function，SCEF)：用于认证授权，支持外部实体发现网络、策略执行、跨运营商的记账、与外部实体互联的相关功能等。
(3)移动管理实体(Mobility Management Entity，MME)：用于核心网络的控制平面管理，其主要功能包括移动性管理、会话管理、接入控制、网元选择、存储用户上下文等。
(4)演进的移动服务位置中心(Evolved Serving Mobile Location Center，E-SMLC)：提供与UE位置相关的信息。
(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。
(9)策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)：该功能实体包含策略控制决策和基于流计费控制的功能。
(10)网络开放功能(Network Exposure Function，NEF)：用于安全地向外部开放由3GPP网络功能提供的业务和能力等。
(11)接入管理功能(Access Management Function，AMF)：主要功能包括无线接入网络控制平面的终结点，非接入信令的终结点，移动性管理，合法监听，接入授权\鉴权等等。
(12)会话管理功能(Session Management Function，SMF)：主要功能包括会话管理，UE的网络互连协议(Internet Protocol，IP)地址分配和管理，选择可管理用户平面功能，策略控制和收费功能接口的终结点，下行数据通知等。

SCS/AS中UE的应用层信息可以被应用于通信网络中。如图1所示，首先SCS/AS中UE的应用层信息会通过API接口传输到SCEF中；此后，SCEF通过S6t接口，与HSS交互以验证SCS/AS是否被授权；之后，SCEF通过T6a接口将信息发送至MME处，用于进行网络的相关控制与优化。
再如图2所示，首先SCS/AS中UE的应用层信息会通过API接口传输到NEF中；此后，NEF与AUSF交互以验证SCS/AS是否被授权；之后，NEF通过NGnef接口将信息发送至AMF或者SMF处，用于进行网络的相关控制与优化。
值得说明的是，本申请实施例中所有SCS/AS和NEF/SCEF之间的交互信息均可采用调用API的方式实现。
在本申请的下述实施例中，会使用一种在定义上更高层次的网元，称为连接优化功能(Connection Optimization Function，COF)网元来指代用于连接优化的网元，例如SCS/AS、E-SMLC等。COF可能是核心网部署的网元(位于网络内部，例如属于NG-CP的范围)，也可能是在核心网外部的应用服务器(例如SCS/AS、E-SMLC，其位于网络外部)，也有可能是属于已有网元的某个功能(例如为SCEF或NEF内部的一个功能模块)。
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”。
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，第二网元获取UE的优化辅助信息；
S302，第二网元根据UE的优化辅助信息向第一网元发送第一消息；
S303，第一网元根据第一消息向第三网元发送用于对UE进行优化处理的信息；
S304，第三网元根据用于对UE进行优化处理的信息对UE进行优化处理。
例如，第一网元可以是能力开放网元(SCEF)，第二网元可以是负责连接优化的网元(如SCS/AS、E-SMLC或COF)，第三网元可以是负责移动性管理的网元(MME)。例如，第一网元可以是能力开放网元(NEF)，第二网元可以是负责连接优化的网元(SCS/AS、E-SMLC或COF)，第三网元可以是负责移动性管理的网元(AMF)或会话管理的网元(SMF)。
例如，第二网元可以接收UE定期地或由事件触发地，向第二网元上报的UE的优化辅助信息，第二网元也可以从其他网元收集UE的优化辅助信息，本申请实施例对此不做具体限定。其中，在具体实施中，UE的优化辅助信息可能包括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。
例如，UE的优化辅助信息可能包括UE的当前位置信息、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、E-UTRAN小区全局标识符(E-UTRAN Cell Global Identifier，ECGI)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。
例如，用于对UE进行优化处理的信息可以包括UE的标识。此外，可能包含对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；或者用于对UE进行优化处理的信息可能包含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；或者用于对UE进行优化处理的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，用于对UE进行优化处理的信息可能包括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/时间段例如可以是根据第一网元或第二网元通过UE的优化辅助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。
需要说明的是，第二网元可以根据UE的优化辅助信息分析得到用于对UE进行优化处理的信息，再通过第一网元告知第三网元，以使第三网元可以根据用于对UE进行优化处理的信息对UE进行优化处理。或者，第二网元也可以直接将UE的优化辅助信息告知给第一网元，第一网元再根据UE的优化辅助信息分析得到用于对UE进行优化处理的信息，并告知第三网元，以使第三网元可以根据用于对UE进行优化处理的信息对UE进行优化处理。第二网元可以直接向第一网元发送携带UE的优化辅助信息的第一消息；第二网元还可以根据UE的优化辅助信息分析得到UE的用于对UE进行优化处理的信息，然后向第一网元发送携带UE的用于对UE进行优化处理的信息的第一消息。即第一信息可能携带UE的优化辅助信息，也可能携带UE的用于对UE进行优化处理的信息。
示例性的，若UE的优化辅助信息包括UE的当前位置信息和运动轨迹信息，第一网元或第二网元可以根据UE的当前位置信息和运动轨迹信息分析预测得到UE在预设时间点或时间段的位置信息。所述UE的优化辅助信息包括所述UE的业务信息，第一网元或第二网元可以根据UE的业务信息分析预测得到对所述UE进行优化处理的时间信息。
本实施例提供的移动网络优化处理方法，通过负责连接优化的网元将UE的应用层信息(即UE的优化辅助信息)或者是基于UE的应用层信息分析得到信息告知能力开放网元，能力开放网元再根据UE的应用层信息或者是基于UE的应用层信息分析得到的信息，获取用于对UE进行优化处理的信息，并告知负责移动性管理的网元或会话管理的网元，以使负责移动性管理的网元或会话管理的网元根据用于对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，基于能力开放网元平台的接口，通过应用层提供的信息，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。
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，COF获取UE的优化辅助信息；
可选的，COF可以接收UE定期地或由事件触发地，向COF上报的UE的优化辅助信息，COF也可以从其他网元收集UE的优化辅助信息，本申请实施例对此不做具体限定。其中，在具体实施中，UE的优化辅助信息可能包括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，COF根据UE的优化辅助信息向SCEF发送第一消息；
S403，SCEF根据第一消息向MME发送用于对UE进行优化处理的信息；
例如，COF基于获取的UE的优化辅助信息，预测UE处于空闲态的时机，并根据预测结果向SCEF发送第一消息。例如，COF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，COF预测UE适合立即转为空闲态，则用于对UE进行优化处理的信息可以包括UE的标识。可选的，用于对UE进行优化处理的信息还可以包括UE进入空闲态的指示信息或者是业务结束的指示信息。
示例性的，COF预测UE适合在一段时间后变为空闲态，则用于对UE进行优化处理的信息可以包括UE的标识和时间信息。可选的，用于对UE进行优化处理的信息还可以包括UE进入空闲态的指示信息或者是业务结束的指示信息。
可选的，COF还可以基于获取的UE的优化辅助信息，直接将UE的优化辅助信息转 发给SCEF，由SCEF预测UE处于空闲态的时机，并根据预测结果向MME发送用于对UE进行优化处理的信息。
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，若是由COF基于UE的优化辅助信息分析预测得到UE处于空闲态的时间，可以在COF处设立定时器，等待超时后再向SCEF发送将UE转换为空闲态的指示信息等。若是SCEF基于UE的优化辅助信息分析预测得到UE处于空闲态的时间，可以在SCEF处设立定时器，等待超时后再向MME发送将UE转换为空闲态的指示信息等。
S404，MME根据用于对UE进行优化处理的信息触发UE的连接释放过程。
可以理解的是，如果用于对UE进行优化处理的信息包括将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。对于相同或相似的概念或过程在本实施例中不再赘述。
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，COF获取UE的优化辅助信息；
S502，COF根据UE的优化辅助信息向NEF发送第一消息；
S503，NEF根据第一消息向AMF发送用于对UE进行优化处理的信息；
S504，AMF根据用于对UE进行优化处理的信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：NEF根据第一消息向SMF发送用于对UE进行优化处理的信息；
S504a：SMF根据用于对UE进行优化处理的信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告知(R)AN删除会话上下文，以及SMF告知告知NG-UP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。
例如，S504和S504a在具体实施过程中，释放的粒度可能存在两种可能：1)释放UE的分组数据单元(Packet Data Unit，PDU)会话(Session)，属于粗粒度的；2)释放UE的QoS流(flow)，属于细粒度的。
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和SMF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和SMF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，基于能力开放网元平台的接口，通过应用层提供的信息，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。对于相同或相似的概念或过程在本实施例中不再赘述。
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，COF获取UE的优化辅助信息；
S602，COF根据UE的优化辅助信息向SCEF发送第一消息；
S603，SCEF根据第一消息向MME发送用于对UE进行优化处理的信息；
例如，COF基于获取的UE的优化辅助信息，预测UE处于连接态的时机，并根据预测结果向SCEF发送第一消息。预测结果可能包含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，COF预测UE适合立即转为连接态，则用于对UE进行优化处理的信息可以包括UE的标识和当前的位置信息。可选的，用于对UE进行优化处理的信息还可以包括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，SCEF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，COF预测UE适合在一段时间后变为连接态，则用于对UE进行优化处理的信息可以包括UE的标识和用于对UE进行优化处理的信息还可以包括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，用于对UE进行优化处理的信息进一步包括预测的业务发生的位置信息和/或者时间信息。
示例性的，COF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。
可选的，COF还可以基于获取的UE的优化辅助信息，直接将UE的优化辅助信息转发给SCEF，由SCEF预测UE处于连接态的时机，并根据预测结果向MME发送用于对UE进行优化处理的信息。
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，若是由COF基于UE的优化辅助信息分析预测得到UE处于连接态的时间，可以在COF处设立定时器，等待超时后再向SCEF发送将UE转换为连接态的指示信息等。若是SCEF基于UE的优化辅助信息分析预测得到UE处于连接态的时间，可以在SCEF处设立定时器，等待超时后再向MME发送将UE转换为连接态的指示信息等。
S604，MME根据用于对UE进行优化处理的信息确定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。
可选的，如果MME接收到的用于对UE进行优化处理的信息包括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E-UTRAN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)用于对UE进行优化处理的信息可能包括对所述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)用于对UE进行优化处理的信息可能包括对所述UE进行优化处理的位置信息，此时，此时MME可以根据用于对UE进行优化处理的信息中的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SCEF发送的用于对UE进行优化处理的信息时，如果只包括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，也可以对用于对UE进行优化处理的信息进行存储，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COF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UE需要处于连接态的指示(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SCEF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SCEF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：SCEF接收到MME发送的第一通知消息后，直接向COF发送第二通知消息，或者等待COF按照API方式调用UE状态获取UE状态信息；
第二通知消息中包含UE的标识，还可能包含UE处于空闲态标识。
需要说明的是，第一通知消息中UE标识和第二通知消息中UE标识可能相同，也可能不同。原因在于，在具体实施过程中，存在一种可能：MME向SCEF发送第一通知消息中包含了内部UE标识，SCEF将内部UE标识映射为外部UE标识，并向COF发送第二通知消息，第二通知消息中包含转换后的外部UE标识。
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。对于相同或相似的概念或过程在本实施例中不再赘述。
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，COF获取UE的优化辅助信息；
S702，COF根据UE的优化辅助信息向NEF发送第一消息；
S703，NEF根据第一消息向AMF发送用于对UE进行优化处理的信息；
S704，AMF确定UE需要进入连接态并根据用于对UE进行优化处理的信息执行相关处理流程。
例如，AMF可以根据用于对UE进行优化处理的信息向(R)AN发送寻呼消息，以请求建立UE的连接，或者AMF根据用于对UE进行优化处理的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，NEF根据第一消息向SMF发送用于对UE进行优化处理的信息；
S704a，SMF确定UE需要激活会话，并根据用于对UE进行优化处理的信息执行相关处理流程。
例如，SMF可以根据用于对UE进行优化处理的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)用于对UE进行优化处理的信息可能包括对所述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)用于对UE进行优化处理的信息可能包括对所述UE进行优化处理的位置信息，此时，此时AMF可以根据用于对UE进行优化处理的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在接收到NEF发送的用于对UE进行优化处理的信息时，如果只包括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可以立即向位置信息对应的(R)AN发送寻呼消息，也可以对用于对UE进行优化处理的信息进行存储，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COF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检测到UE处于空闲态时，向NEF发送第一通知消息；
例如AMF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NEF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：NEF接收到AMF发送的第一通知消息后，向COF发送第二通知消息；
第二通知消息中包含UE的标识，还可能包含UE处于空闲态标识。
同样值得一提的是，第一通知消息中UE标识和第二通知消息中UE标识可能相同，也可能不同。原因在于，在具体实施过程中，存在一种可能：AMF向NEF发送第一通知消息中包含了内部UE标识，NEF将内部UE标识映射为外部UE标识，并向COF发送第二通知消息，第二通知消息中包含转换后的外部UE标识。
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，基于能力开放网元平台的接口，通过应用层提供的信息，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。
