随着移动通信网络的演进、以及大量新应用的不断出现，在不同应用领域逐渐产生了不同的业务需求。一般来说，人们一直追求具有大带宽、低时延、高可靠性这三大特性的移动通信系统。在目前的移动通信网络中，用户设备(User Equipment：UE)从空闲态恢复到连接状态需要进行多条信令的交互，时延相对较高。为此第三代合作伙伴计划(3rd Generation Partnership Project：3GPP)引入了新的UE移动性管理状态，即挂起状态(Suspend State)。
挂起状态下，UE和接入网之间的空口资源被释放后，UE和接入网会保存空口连接的上下文；且在核心网中该UE的上下文(Context)、及承载业务的网络资源如分组数据网络(Packet Data Network：PDN)连接、承载等都会被继续保留。在挂起状态下，因UE和接入网之间的空口资源被释放，从而能够达到节能省电的目的；同时无线接入网节点(Radio Access Network Node：RAN Node)和核心网保留了该UE所有的连接和上下文，因而当有数据到达时，UE可以通过简化的信令交互快速恢复UE与接入网之间的空口连接，即可建立数据连接，而不用重新建立连接和上下文。因此挂起状态可以很好地满足低时延的要求。
由于在挂起状态下网络侧保留了该UE所有的连接和用户上下文，网络侧会认为UE仍处于连接态(Connected State)，即无线接入网节点与核心网之间的信令连接和用户面连接处于激活状态；一旦UE移动离开了该RAN Node的覆盖范围，则核心网需要执行切换流程来更新原有的信令连接和用户面连接。UE的移动速度过快会导致RAN Node频繁切换，核心网需要频繁地执行切换流程来保持UE的挂起状态，从而导致较大的信令负担、降低网络性能。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
为了解决现有技术通信系统中因保持UE的挂起状态可能导致较大的信令负担而降低网络性能的问题，本发明实施例基于图1所示的通信系统中提出了一种解决方案，用以提高通信系统的网络性能。如图1所示，本发明实施例提供了一种通信系统100。该通信系统100可以包括如下通信实体：
至少一台UE 102；
至少一个无线接入网(Radio Access Network：RAN)104，可以包括由基站(Base Station：BS)、分布式基站、云无线接入网(Cloud RAN：CRAN)设备、或者由无线网络控制器(Radio Network Controller：RNC)和基站共同组成的接入网设备，本文统称为无线接入网节点RAN Node；如附图1中仅以基站BS为例；
控制面实体(Control Plane Entity：CPE)106，用于提供控制面网络功能的实体；CPE106负责控制面网络功能的执行。CPE 106可以是如移动性管理实体(Mobility Management Entity：MME)或服务GPRS支持节点(Serving GPRS Support Node：SGSN)这类形态的物理网元，也可以是虚拟机、或软件程序包；
用户面实体User Plane Entity(UPE)108，用于提供用户面网络功能的实体，其负责用户面网络功能的执行。UPE 108可以是如服务网关(Serving Gateway：S-GW)或PDN网关(PDN Gateway：P-GW)这类形态的物理网元，也可以是虚拟机、或软件程序包；
应用功能实体(Application Function：AF)110，用于向CPE106提供应用所需要的业务需求和策略，例如服务水平协议(Service Level Agreement：SLA)。CPE 106可以根据AF110提供的业务需求和策略确定UE的服务策略，例如服务质量(Quality of Service：QoS)。AF 110还可以用于提供应用服务，其可以是用于提供用户访问业务的应用服务器，如QQ服务器；
数据网络(Data Network：DN)112，可以是各种分组数据网络或非分组数据网络，例如因特网、或运营商的本地数据网络。
在本发明实施例如图1所述的通信系统100中，UE 102通过RAN 104接入网络，由CPE106和UPE 108分别为UE 102提供控制面网络功能和用户面网络功能，使得UE 102可以通过UPE 108连接到DN 112并获得相应的服务。
在本发明实施例中，通信系统100可以为各种3GPP通信系统，例如通用分组无线系统(general packet radio system,GPRS)，通用移动通讯系统(universal mobile telecommunications system,UMTS)，演进分组系统(evolved packet system)演进分组系统。术语“系统”可以和“网络”相互替换。此外，通信系统100还可以适用于未来的3GPP通 信系统或其他标准组织定义的移动通信系统，例如下一代网络通信系统(Next Generation communication system，NexGen)。通信系统100也可以为非3GPP通信系统。本发明实施例描述的系统架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
在本发明实施例中，所述无线接入网RAN 104可以为各种无线接入技术(radio access technology，RAT)系统，譬如例如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single carrier FDMA，SC-FDMA)和其它系统等。术语“系统”可以和“网络”相互替换。CDMA系统可以实现例如通用无线陆地接入(universal terrestrial radio access，UTRA)，CDMA2000等无线技术。UTRA可以包括宽带CDMA(wideband CDMA，WCDMA)技术和其它CDMA变形的技术。CDMA2000可以覆盖过渡标准(interim standard，IS)2000(IS-2000)，IS-95和IS-856标准。TDMA系统可以实现例如全球移动通信系统(global system for mobile communication，GSM)等无线技术。OFDMA系统可以实现诸如演进通用无线陆地接入(evolved UTRA，E-UTRA)、超级移动宽带(ultra mobile broadband，UMB)、IEEE802.11(Wi-Fi)，IEEE 802.16(WiMAX)，IEEE 802.20，Flash OFDMA等无线技术。UTRA和E-UTRA是UMTS以及UMTS演进版本。3GPP在长期演进(long term evolution，LTE)和基于LTE演进的各种版本是使用E-UTRA的UMTS的新版本。此外，所述通信系统100还可以适用于面向未来的通信技术。本发明实施例描述的系统架构以及业务场景是为了更加清楚的说明本发明实施例的技术方案，并不构成对于本发明实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
本发明实施例中，所述RAN Node 104是一种部署在无线接入网中用于为UE提供无线通信功能的装置。所述RAN Node 104可以包括各种形式的宏基站，微基站(也称为小站)，中继站，接入点等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如，在LTE系统中，称为演进的节点B(evolved NodeB，eNB或者eNodeB),在第三代(3rd generation，3G)系统中，称为节点B(Node B)等；也可以适用于面向未来通信技术的为UE提供无线通信功能的装置。
本发明实施例中所涉及到的UE可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。所述UE也可以称为移动台(mobile station,简称MS)，终端(terminal)，终端设备(terminal equipment)，还可以包括用户单元(subscriber unit)、蜂窝电话(cellular phone)、智能电话(smart phone)、无线数据卡、个人数字助理(personal digital assistant，PDA)电脑、平板型电脑、无线调制解调器(modem)、手持设备(handheld)、膝上型电脑(laptop computer)、无绳电话(cordless phone)或者无线本地环路(wireless local loop，WLL)台、机器类型通信(machine type communication,MTC)终端等。为方便描述，本发明所有实施例中，上面提到的设备统称为UE。
本发明实施例中所涉及的各通信实体之间交互的所有消息，如Context Request消息、Context Response消息、Initial Context Setup消息、Initial Context Complete Setup消息、Attach Accept消息、NAS Request消息、Path Switch Request消息、Path Switch Request Ack消息等，都仅是示例性的描述，可以使用各种不同移动通信标准(如2G移动通信系统、3G移动通信系统、4G移动通信系统或5G移动通信系统)中定义的其他消息来实现，也可以是运营商或设备制造商根据使用现实移动通信系统中自己定义的非标准消息来实现。
在本发明实施例图1所示的通信系统中，参见图2，提供了本发明实施例提供的一种通信方法，在该通信方法中可以包括：
202部分：当用户设备UE 102接入到网络时，控制面实体CPE 106判断是否允许开启UE102上的挂起功能，即UE 102的挂起状态是否被允许使用；
CPE 106可以根据UE 102所请求的业务信息、或UE 102的设备类型信息、或UE 102的终端能力信息、或网络能力信息、或者UE 102的移动轨迹信息等来判断是否允许开启UE102上的挂起功能。上述网络能力信息可以是网络中的网络设备的能力信息，例如当前为UE提供服务的无线接入网节点RAN Node是否支持挂起功能的信息，如当前RAN Node不支持挂起功能，则可以认为当前网络不支持挂起功能。当然CPE 106也可以根据上述信息中某几种的组合来判断，本发明对此不做限定。
204部分：CPE 106将202部分的判断结果发送给UE 102当前连接的RAN Node，可以由该RAN Node根据上述判断结果来确定是否开启该UE 102上的挂起功能；
需要说明的是，当CPE106发送的上述判断结果指示RAN Node允许开启UE 102上的挂 起功能时，该RAN Node可以在满足一定的触发条件下开启该UE 102上的挂起功能，即通知UE 102进入挂起状态。如果CPE106发送的上述判断结果指示该RAN Node不允许开启UE102上的挂起功能，则即使上述触发条件被满足、或者该UE 102主动发起请求进入挂起状态，该RAN Node也可以不执行开启该UE 102上挂起功能的操作。
当然，CPE 106也可以将判断结果直接发送给UE 102，由UE 102根据上述判断结果来确定是否开启其上的挂起功能。类似地、如果CPE106发送的上述判断结果指示允许开启UE 102上的挂起功能，则该UE 102可以在满足一定的触发条件下进入挂起状态。如果CPE106发送的上述判断结果指示不允许开启UE 102上的挂起功能，则即使上述触发条件被满足，该UE 102也不会进入挂起状态。
本发明实施例中，CPE 106发送的判断结果包含用于指示挂起功能允许开启或不允许开启的指示信息。在具体实现中指示信息可以是一个字段，例如该字段为一特定值表示允许开启挂起功能，而该字段为另一个特定值时则表示不允许开启挂起功能。本发明实施例对于字段值的具体定义不做限定。
可选地，当CPE 106的判断结果是允许开启UE 102上的挂起功能时，该判断结果中还可以包括挂起触发条件信息，用于指示RAN Node或UE 102可以触发进入挂起状态的条件。例如触发条件信息可以是时长信息，RAN Node或UE 102可以根据该时长信息设置定时器，当RAN Node与UE 102之间无数据传输的间隔时间超出该时长信息对应的时长，即上述定时器超时，RAN Node或UE 102可以请求进入挂起状态。
可选地，当CPE 106的判断结果是允许开启UE 102上的挂起功能、且决CPE 106将判断结果发送给RAN Node时，该判断结果中还可以包括RAN Node的网络拓扑信息。RAN Node可以用该网络拓扑信息决定该UE 102上的挂起状态能够保持的范围，比如可以保持该UE的挂起状态的小区列表(Suspend Cell List)，即在这些小区内可以保持该UE的挂起状态。当UE 102在这个范围内移动时，该UE 102可以保持挂起状态、且该UE 102当前连接的RAN Node无需通知核心网。需要说明的是，Suspend Cell List可以是不同RAN Node下的小区，此时不同的RAN Node之间需要支持X2接口。
相比于现有技术所有UE上的挂起功能都默认允许被开启，本发明上述实施例通过CPE根据业务信息、或UE的设备类型信息、或终端能力信息、或网络能力信息、或者UE的移动轨迹信息等来判断是允许开启还是不允许开启UE上的挂起功能。采用本发明实施例的方 案，对于那些为保持UE的挂起状态可能导致较大的信令负担的情形，就可以不允许开启该UE的挂起功能，从而减少了信令负担、提高了网络性能。
在本发明上述实施例中，对于CPE经过判断确定允许开启UE上的挂起功能的情形，CPE还可以进一步在判断结果中包含挂起触发条件信息，用于指示可以开启该UE上的挂起功能的条件，即通过对UE何时触发进入挂起状态进行设置，可以避免UE上挂起状态的盲目触发，实现减少保持UE挂起状态的信令负担的目的，从而提升网络性能。
另一方面，在CPE发送的判断结果中还可以进一步包括RAN Node的网络拓扑信息，设置该UE的挂起状态可以保持的范围，在该范围内UE可以保持挂起状态且不需要通知核心网。这样可以避免在该范围之外UE仍要保持挂起状态，减少不合理的信令负担、提高网络性能。
下面结合图3，对本发明实施例提供的技术实施方式一进行说明。
本技术实施方式一由CPE根据该UE的设备类型信息判断是否允许开启该UE上的挂起功能，并将判断结果直接发送到RAN Node。UE的设备类型信息具体可以是用户签约数据中的UE使用类型(UE Usage Type)，设备类型值具体可以是移动宽带(Mobile Broadband：MBB)UE，蜂窝物联网(Cellular Internet of Things：CIoT)UE等。
302部分：用户设备UE向当前为该UE提供服务的现控制面实体CPE发送接入请求消息如Attach Request消息，其中包含该UE的标识信息；
需要说明的是，UE的标识信息可以是运营商为该UE分配的永久标识，如国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)等；也可以是网络为UE分配的临时标识，如全球唯一临时UE标识(Globally Unique Temporary UE Identity，GUTI)等；UE的标识信息还可以是用于推导出UE标识的信息，具体可以是网络为UE分配可用于识别该UE的信息，如隧道端点标识(tunnel endpoint identifier，TEID)或IP地址等。
304部分：现CPE向之前为UE提供服务的原CPE发送Context Request消息，请求获取该UE的上下文(Context)；
306部分：原CPE向现CPE发送Context Response消息，将该UE的上下文发送给现CPE；该UE的上下文中可以包含该UE的设备类型信息；
当然，也可能存在现CPE无法成功从原CPE获取到该UE的上下文的情况，例如现CPE 无法连接上原CPE，或原CPE已将该UE的上下文删除。这种情况下，现CPE可以向签约数据库如归属签约用户服务器(Home Subscriber Server，HSS)发送签约数据请求消息，请求获取该UE的签约数据；接收到签约数据请求消息的HSS，将该UE的签约数据发送到现CPE，该签约数据中可以包含该UE的设备类型信息。
可选地，存在原CPE与现CPE为同一个CPE实体的情况，例如UE在发送接入请求消息时仍然处于原CPE的服务范围。在这种情况下，现CPE不会发起Context Request消息，而从CPE本地存储的数据中获取到该UE的上下文。
308部分：现CPE根据该UE的设备类型信息判断是否允许开启该UE上的挂起功能；具体实现时，现CPE根据该UE的设备类型信息就能知晓该UE是何种类型的终端，现CPE可以对某些特定类型的用户设备设置为允许开启该UE上的挂起功能，对其他特定类型的用户设备则不允许开启其上的挂起功能。UE的设备类型信息与是否允许开启挂起功能的对应关系可以预先配置在现CPE上。
310部分：现CPE将308部分中的判断结果通过Initial Context Setup消息发送给该UE当前连接的RAN Node；具体可能有如下310(a)或310(b)两种情形。
310(a)部分：如果308部分中现CPE根据该UE的设备类型信息确定允许开启该UE上的挂起功能，则现CPE向该UE当前连接的RAN Node发送Initial Context Setup消息，其中包含指示挂起功能允许开启的指示信息，用于指示该RAN Node可以为该UE开启挂起功能。
可选地，现CPE向RAN Node发送的消息中还可以包括挂起触发条件信息，用于指示RAN Node可以触发开启该UE的挂起功能的条件，也即触发该UE进入挂起状态的条件。例如触发条件信息可以是时长信息，RAN Node可以根据该时长信息设置定时器，当RAN Node与UE之间无数据传输的间隔时间超出该时长信息对应的时长，即上述定时器超时，RAN Node可以触发该UE进入挂起状态。
可选地，现CPE向RAN Node发送的消息中还可以包括RAN Node的网络拓扑信息，RAN Node可以用该网络拓扑信息决定该UE上的挂起状态能够保持的范围，比如可以保持该UE的挂起状态的小区列表(Suspend Cell List)，即在这些小区内可以保持该UE的挂起状态。当UE在这个范围内移动时，该UE可以保持挂起状态、且该UE当前连接的RAN Node无需通知核心网。
310(b)部分：作为现CPE判断的另一种可能结果，如果308部分中现CPE根据该UE的设 备类型信息确定不允许开启该UE上的挂起功能，则现CPE向该UE当前连接的RAN Node发送的消息中包含指示挂起功能不允许开启的指示信息，用于指示该RAN Node不可以为该UE开启挂起功能。
312部分：无论是上述310(a)或310(b)的何种情形，RAN Node都可以向现CPE发送Initial Context Setup Complete消息，作为Initial Context Setup消息的响应，用于表示RAN Node已接收到了是否允许开启UE上的挂起功能的指示信息。
本发明技术实施方式一通过CPE根据UE的设备类型信息判断是否允许开启该UE上的挂起功能，可以减少为保持UE的挂起状态可能导致较大的信令负担，从而提高网络性能；在允许开启UE上的挂起功能的情形下，CPE还可以通过挂起触发条件信息对UE何时触发进入挂起状态进行设置，避免盲目触发该UE进入挂起状态的，实现减少保持UE挂起状态的信令负担的目的，从而提升网络性能；也可以通过网络拓扑信息来设置该UE的挂起状态可以保持的范围，这样能更有效使用挂起机制，进一步减少信令负担。
下面结合图4，对本发明实施例提供的技术实施方式二进行说明。
在该实施方式二中，与图3对应的实施方式一类似，也是由现CPE根据UE的设备类型信息判断是否允许开启该UE上的挂起功能；与上述实施方式一所不同的是，现CPE将判断结果被直接发送给该UE。
本实施方式二中的402～408部分，可以与图3及实施方式一中的302～308部分的实现类似，这里不赘述。
410部分：现CPE将408部分中的判断结果通过Attach Accept消息发送给该UE；具体可能有如下410(a)或410(b)两种情形。
410(a)部分：如果408部分中现CPE根据该UE的设备类型信息确定允许开启该UE上的挂起功能，则现CPE向该UE发送Attach Accept消息，其中包含指示挂起功能允许开启的指示信息，用于指示该UE可以开启挂起功能。
可选的，Attach Accept消息中还可以包括挂起触发条件信息，用于指示该UE可以触发进入挂起状态的条件。例如触发条件信息可以是时长信息，该UE可以根据该时长信息设置定时器，当RAN Node与UE之间无数据传输的间隔时间超出该时长信息对应的时长，即上 述定时器超时，UE可以请求进入挂起状态。
410(b)部分：作为现CPE判断的另一种可能结果，如果408部分中现CPE根据该UE的设备类型信息确定不允许开启该UE上的挂起功能，则现CPE向该UE发送Attach Accept消息，其中包含指示挂起功能不允许开启的指示信息，用于指示该UE不可以开启挂起功能。
本发明技术实施方式二通过CPE根据UE的设备类型信息判断是否允许开启UE上的挂起功能，可以减少为保持UE的挂起状态可能导致较大的信令负担，从而提高网络性能；在允许开启UE上的挂起功能的情形下，CPE还可以通过挂起触发条件信息对UE何时触发挂起状态进行设置，避免盲目触发UE进入挂起状态，实现减少保持UE挂起状态的信令负担的目的，从而提升网络性能。
本发明上述技术实施方式一和二，都是由现CPE根据该UE的设备类型信息判断是否允许开启该UE上的挂起功能。作为本发明技术实施方式的变形，还可以由现CPE根据该UE的业务信息来判断是否允许开启该UE上的挂起功能。UE的业务信息可以由现CPE从UE接收的NAS Request消息中获得。UE的业务信息可以是接入点名称(Access Point Name：APN)、业务类型等用于标识UE所使用业务的信息；其中业务类型可以是用来指定该UE需要申请的业务对应的Application ID。业务信息与是否允许开启挂起功能的对应关系可以预先配置在CPE上，例如当UE请求的业务是位置强相关业务时，CPE确定不允许开启UE上的挂起功能；如果UE请求的业务不是位置强相关业务，则CPE确定允许开启该UE上的挂起功能。位置强相关业务可以是本地消息业务、本地广告推送业务、或本地视频流业务等；这些业务和UE当前所处的位置强相关，一旦UE离开当前能够提供服务的位置如商场、图书馆等区域，业务就会中断。以在特定商场范围内提供的本地广告推送业务为例，一旦UE离开了该商场的范围，就不能继续享受在该商场范围内才提供的本地广告推动业务了。
挂起状态下核心网侧通常默认UE处于原先所在的小区，这样通过UE所请求业务的业务类型来判断是否允许开启UE上的挂起功能，可以避免在UE请求的业务是位置强相关业务时仍开启该UE上的挂起功能，从而避免在UE位置实际上不可知的情况下降低了业务质量或导致业务不可用。
当然，移动通信网络中的网络设备如RAN Node存在支持挂起机制和不支持挂起机制的不同情况，CEP还可以根据网络能力信息，比如移动通信系统中网络设备的能力信息来判断是否允许开启UE上的挂起功能。网络能力信息可以是当前为UE提供服务的RAN Node是否支持挂起功能的信息，如当前RAN Node不支持挂起功能，相应可以认为当前网络不支持挂起功能，则不允许开启该UE上的挂起功能。
下面结合图5，对本发明实施例提供的技术实施方式三进行说明。
本技术实施方式三由CPE根据UE的移动轨迹信息判断是否允许开启该UE上的挂起功能，并将判断结果被发送到该UE当前连接的RAN Node。
502部分：用户设备UE向当前为该UE提供服务的现控制面实体CPE发送接入请求消息如Attach Request消息，其中包含该UE的标识信息；
需要说明的是，UE的标识信息可以是运营商为该UE分配的永久标识如IMSI等，也可以是网络为UE分配的临时标识如GUTI等；UE的标识信息还可以是用于推导出UE标识的信息，具体可以是网络为UE分配可用于识别该UE的信息，如TEID或IP地址等。
504部分：现CPE向之前为UE提供服务的原CPE发送Context Request消息，请求获取该UE的上下文(Context)；
可选地，存在原CPE与现CPE为同一个CPE实体的情况，例如UE在发送接入请求消息时仍然处于原CPE的服务范围。在这种情况下，现CPE不会发起Context Request消息，而从CPE本地存储的数据中获取到该UE的上下文。
506部分：原CPE向现CPE发送Context Response消息，将该UE的上下文发送给现CPE；该UE的上下文中可以包含该UE的移动轨迹信息；
508部分：现CPE根据该UE的移动轨迹信息判断是否允许开启该UE上的挂起功能；
该UE的移动轨迹信息，可以是现CPE上存储的该UE的历史移动轨迹信息，也可以是现CPE从原CPE上获取的该UE的历史移动轨迹信息，或者两者的组合。移动轨迹信息与是否允许开启挂起功能的对应关系、或判断规则可以预先配置在现CPE上。
当UE处于移动状态时，由于小区、RAN Node、或者CPE的服务范围的限制，当UE移动离开该服务范围时，会导致之前为UE提供服务的实体如RAN Node或CPE不能再为该UE 提供服务了，需要切换到新的通信实体来为该UE提供持续性的服务；即移动通信网络中切换小区、切换RAN Node、及切换CPE等情况。当UE的移动轨迹信息表明该UE移动速度过快、或者切换频繁，则现CPE可以确定不允许开启该UE上的挂起功能，以避免为保持UE的挂起状态而频繁地执行切换流程。相应地，如果UE的移动轨迹表明该UE是相对固定、或很少发生切换，则现CPE可以确定允许开启该UE上的挂起功能。
510部分：现CPE将508部分中的判断结果通过Initial Context Setup消息发送给该UE当前连接的RAN Node；具体可能有如下510(a)或510(b)两种情形。
510(a)部分：如果508部分中现CPE确定允许开启该UE上的挂起功能，则现CPE向该UE当前连接的RAN Node发送的消息中包含指示挂起功能允许开启的指示信息，用于指示该RAN Node可以为该UE开启挂起功能。
可选地，现CPE向RAN Node发送的消息中还可以包括挂起触发条件信息，用于指示RAN Node可以触发UE进入挂起状态的条件；或者包括RAN Node的网络拓扑信息，用于设置该UE上的挂起状态能够保持的范围。
510(b)部分：作为另一种可能结果，如果508部分中现CPE确定不允许开启该UE上的挂起功能，则现CPE向该UE当前连接的RAN Node发送Initial Context Setup消息，其中包含指示挂起功能不允许开启的指示信息。
512部分：RAN Node向现CPE发送Initial Context Setup Complete消息，用于表示RAN Node已接收到了是否允许开启UE上的挂起功能的指示信息。
本发明技术实施方式三通过CPE根据UE的移动轨迹信息来判断是否允许开启UE上的挂起功能，避免为某些移动范围过大或切换频繁的用户设备开启挂起功能；从而可以减少信令负担、提高网络性能；在允许开启UE上的挂起功能的情形下，可以设置挂起触发条件信息避免UE上挂起状态被盲目触发，还可以通过网络拓扑信息来设置该UE的挂起状态可以保持的范围，进一步减少不必要的信令负担、提高网络性能。
下面结合图6，对本发明实施例提供的技术实施方式四进行说明。
在该实施方式四中，与图5对应的实施方式三类似，也是由现CPE根据UE的移动轨迹 信息判断是否允许开启该UE上的挂起功能；所不同的是现CPE将判断结果发送给该UE。
本实施方式四中的602～608部分，可以与图5及实施方式三中的502～508部分的实现类似，这里不赘述。
610部分：现CPE将608部分中的判断结果通过Attach Accept消息发送给该UE；具体可能有如下610(a)或610(b)两种情形。
610(a)部分：如果608部分中现CPE确定允许开启该UE上的挂起功能，则现CPE向该UE发送Attach Accept消息，其中包含指示挂起功能允许开启的指示信息，用于指示该UE可以开启挂起功能。
可选的，Attach Accept消息中还可以包括挂起触发条件信息，用于指示该UE可以触发进入挂起状态的条件。触发条件信息可以是时长信息，该UE可以根据该时长信息设置定时器，当RAN Node与UE之间无数据传输的间隔时间超出该时长信息对应的时长，即上述定时器超时，UE可以请求进入挂起状态。
610(b)部分：作为另一种可能结果，如果608部分中现CPE确定不允许开启该UE上的挂起功能，则现CPE向该UE发送Attach Accept消息，其中包含指示挂起功能不允许开启的指示信息，用于指示该UE不可以开启挂起功能。
本发明技术实施方式四通过CPE根据UE的移动轨迹信息判断是否允许开启该UE上的挂起功能，避免开启某些移动范围过大或切换频繁的用户设备上的挂起功能；在允许开启UE上的挂起功能的情形下，可以设置挂起触发条件信息避免UE上挂起状态被盲目触发，以进一步减少不必要的信令负担、提高网络性能。
下面结合图7，对本发明实施例提供的技术实施方式五进行说明。
本发明实施例的技术实施方式五是在用户设备UE发生无线接入网节点RAN Node切换时，由当前为该UE提供服务的现CPE根据该UE的移动轨迹信息判断是否允许开启该UE上的挂起功能，并将判断结果发送到目的RAN Node。
702部分：UE与源RAN Node、目的RAN Node之间执行切换准备流程和切换执行流程；源RAN Node将所保存的该UE的上下文和数据发送到目的RAN Node；
704部分：目的RAN Node向现CPE发送切换请求消息，比如Path Switch Request消息，该切换请求消息中可以包含该UE的标识；
需要说明的是，UE的标识信息可以是运营商为该UE分配的永久标识如IMSI等，也可以是网络为UE分配的临时标识如GUTI等；UE的标识信息还可以是用于推导出UE标识的信息，具体可以是网络为UE分配可用于识别该UE的信息，如TEID或IP地址等。
706部分：现CPE向之前为UE提供服务的原CPE发送Context Request消息，请求获取该UE的上下文(Context)；
可选地，存在原CPE与现CPE为同一个CPE实体的情况，例如UE发生RAN Node切换后，仍然处于原CPE的服务范围。在这种情况下，现CPE不会发起Context Request消息，而从CPE本地存储的数据中获取到该UE的上下文。
708部分：原CPE向现CPE发送Context Response消息，将该UE的上下文发送给现CPE；该UE的上下文中可以包含该UE的移动轨迹信息；
710部分：现CPE根据该UE的移动轨迹信息判断是否允许开启该UE上的挂起功能。
与本发明实施例上述实时方式三或四类似，当UE的移动轨迹信息表明该UE移动速度过快、或者切换频繁，则CPE确定不允许开启该UE上的挂起功能，以避免频繁地执行切换流程来保持UE的挂起状态。相应地，如果UE的移动轨迹表明该UE是相对固定、或很少发生切换，则现CPE确定允许开启该UE上的挂起功能。
712部分：现CPE将710部分中的判断结果通过切换请求应答消息比如Path Switch Request Ack消息发送给目的RAN Node；具体可能有如下712(a)或712(b)两种情形。
712(a)部分：如果710部分中现CPE确定允许开启该UE上的挂起功能，则现CPE向目的RAN Node发送的切换请求应答消息中包含指示挂起功能允许开启的指示信息，用于指示该目的RAN Node可以开启该UE上的挂起功能。
可选地，切换请求应答消息中还可以包括挂起触发条件信息，用于指示该目的RAN Node可以触发UE进入挂起状态的条件，还可以包括网络拓扑信息，目的RAN Node可以用该网络拓扑信息决定该UE上的挂起状态能够保持的范围。
712(b)部分：作为另一种可能结果，如果710部分中现CPE确定不允许开启该UE上的挂 起功能，则现CPE向目的RAN Node发送的切换请求应答消息中包含指示挂起功能不允许开启的指示信息。
本发明技术实施方式五，在UE发生RAN Node切换情形下，通过CPE根据UE的移动轨迹信息判断是否允许开启该UE上的挂起功能，并将判断结果发送给切换后的目的RAN Node，这样可以避免为某些移动范围过大或切换频繁的用户设备开启挂起功能；从而可以减少信令负担、提高网络性能；在允许开启UE上的挂起功能的情形下，可以设置挂起触发条件信息避免UE上挂起状态被盲目触发，还可以通过网络拓扑信息来设置该UE的挂起状态可以保持的范围，进一步减少不必要的信令负担、提高网络性能。
需要说明的是，上述实施方式的方案分别是CPE根据UE所请求的业务信息、或UE的设备类型信息、或UE的终端能力信息、或网络能力信息、或者UE的移动轨迹信息来判断是否允许为UE开启挂起功能。如本说明书前面所述，CPE也可以根据上述信息中某几种的组合来判断是否允许为UE开启挂起功能。比如CPE可以结合UE的设备类型信息和UE的移动轨迹信息来判断是否允许开启UE上的挂起功能。
以物流跟踪的应用场景为例，物流公司可以在包裹上放置用作传感器的IoT设备，该IoT设备可视为本发明实施例的用户设备UE。该IoT设备即UE会定期上报该包裹的位置，以便跟踪和掌握包裹的物流信息。如果包裹在物流集散地如码头、车站等长时间驻留时，UE的位置变化不大，网络侧可以为UE开启挂起功能；但如果包裹处于运输状态，如在汽车、铁路上，此时UE的移动速度过快，并不适合为UE开启挂起功能。因此在物流跟踪的场景中，网络侧的CPE可以结合UE的设备类型信息和UE的移动轨迹信息来判断是否允许开启该UE的挂起功能。具体来说，CPE可以先根据UE的设备类型信息判断是否允许开启该UE的挂起功能，并进一步根据UE的移动轨迹信息来判断。
以上面提及的在特定商场范围内提供本地广告推送业务为例，CPE可以根据该UE的业务信息和该UE的移动轨迹信息一起来判断是否允许开启该UE上的挂起功能。例如当UE请求的业务是位置强相关业务、且该UE的移动轨迹信息表明该UE移动速度过快或切换频繁，则CPE可以确定不允许开启UE上的挂起功能；对于其他情况，如果UE请求的业务不是位置强相关业务、或者虽然UE请求的业务是位置强相关业务、但该UE的移动轨迹信息表明该UE的位置相对固定，则CPE确定允许开启该UE上的挂起功能。
进一步地，CPE也可以根据UE请求的业务信息和UE的设备类型信息一起来判断是否 允许开启该UE上的挂起功能。对于一些UE，比如某些IoT设备，在通常情况下该IoT设备请求或执行的业务是定期上报数据的业务，此时CPE可以确定允许开启该IoT设备上的挂起功能；但在某些特殊情况下，比如该IoT设备出现了故障告警、或处于远程控制状态，根据业务的需要，该IoT设备应该始终保持连接状态，此时CPE可以确定不允许开启该IoT设备上的挂起功能。
很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。

可选地、所述消息还包括挂起触发条件信息，用于指示所述UE可以触发开启挂起功能的条件。
相比于现有技术所有UE上的挂起功能都默认允许被开启，本发明实施例提供的控制面实体CPE、无线接入网节点RAN Node之间相互配合，通过CPE根据业务信息、或UE的设备类型信息、或终端能力信息、或网络能力信息、或者UE的移动轨迹信息等来判断是允许开启还是不允许开启UE上的挂起功能。采用本发明实施例的方案，对于那些为保持UE的挂起状态可能导致较大的信令负担的情形，就可以不允许开启该UE的挂起功能，从而减少了信令负担、提高了网络性能。
在本发明上述实施例中，进一步可以在判断结果中包含挂起触发条件信息，用于指示可以开启该UE上的挂起功能的条件，即通过对UE何时触发进入挂起状态进行设置，可以避免UE上挂起状态的盲目触发，实现减少保持UE挂起状态的信令负担的目的，从而提升网络性能；还可以在判断结果中包含网络拓扑信息，设置该UE的挂起状态可以保持的范围，在该范围内UE可以保持挂起状态且不需要通知核心网。这样可以避免在该范围之外UE仍要保持挂起状态，减少不合理的信令负担、提高网络性能。
