在第三方面的一种可能的实现方式中，定位模块具体用于：根据该空闲态UE发起的位置更新流程，确定该空闲态UE请求更新的小区位置标识是否为该预设位置标识，当确定该空闲态UE请求更新的小区位置标识为该预设位置标识时，获取该空闲态UE的临时用户标识。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例中涉及的接入网设备可以是全球移动通讯(Global System of Mobile communication，简称GSM)或码分多址(Code Division Multiple Access，简称CDMA)中的基站(Base Transceiver Station，简称BTS)中，也可以是宽带码分多址(Wideband Code Division Multiple Access，简称WCDMA)中的基站(NodeB，简称NB)，还可以是LTE网络中的演进型基站(evolved NodeB，简称eNB)、接入点(access point，AP)或者中继站，也可以是下一代网络(即5G网络)中的基站等，在此不作限定。
另外，本发明实施例中涉及的用户设备，可以是无线终端。无线终端 可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其它处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与至少一个核心网进行通信。无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和带有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。无线终端也可以称为用户单元(Subscriber Unit)、用户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile Station)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)或用户设备(User Equipment)，在此不作限定。
图1为本发明实施例一提供的对空闲态用户设备进行定位的方法的流程图，如图1所示，本实施例的方法可以包括以下步骤：
步骤101、接入网设备向小区内的UE发送寻呼(Paging)消息，该寻呼消息中包括读取指示信息，该读取指示信息用于指示小区内的UE读取系统消息。
本实施例中，接入网设备发送寻呼消息的目的是通知小区内的所有UE(包括连接态UE和空闲态UE)系统信息发生了变化，接入网设备寻呼的对象为小区内的所有UE，由于需要寻呼空闲态UE，因此该寻呼消息的类型为Paging Type 1，Paging Type 1应用于UE处于空闲态、CELL_PCH、URA_PCH状态UE的寻呼，即Paging Type 1适用于对没有建立无线链路的UE进行寻呼。由于接入网设备在发送寻呼消息之前只能获取小区内的连接态UE的标识信息，并不能获取小区内空闲态UE的标识信息，因此，接入网设备向小区内的UE发送寻呼消息时，并没有对小区内的UE作区分，即不是针对某个UE发送寻呼消息，该寻呼消息中也不包括要寻呼的UE的标识信息。
本实施例中，接入网设备在寻呼消息中携带读取指示信息，该读取指示信息用于指示小区内的所有UE读取系统消息。该读取指示信息可以为系统中已有的广播控制信道(Broadcast Control Channel，简称BCCH)修改信息(modification info)，也可以为本发明新定义的一种指示信息。以 BCCH modification info为例，若接入网设备在寻呼消息中携带了BCCH modification info，那么小区内任何在空闲态、CELL_PCH(UMTS)或URA_PCH(UMTS)状态的UE会重新读取系统消息。
UMTS、LTE等网络中寻呼信道上有很多寻呼比特位，该寻呼比特位即用于指示寻呼的比特位，每个UE有自己特定的寻呼比特位，UE通过其IMSI可以计算出自己在寻呼信道的寻呼比特位，然后该UE监听自己的寻呼比特位是否被置1，如果该UE监听到自己的寻呼比特位被置1，则确定自己被寻呼了。本实施例中，由于网络侧不知道空闲态UE的信息，即不知道该寻呼哪些UE，因此，接入网设备将寻呼信道中的所有寻呼比特位都置1，以实现对小区内的所有UE进行寻呼。
步骤102、空闲态UE接收接入网设备发送的寻呼消息。
小区内的空闲态UE和连接态UE都会接收接入网设备发送的寻呼消息，根据寻呼消息中包括的读取指示信息，准备读取系统消息。
步骤103、接入网设备发送系统消息，该系统消息中的小区位置标识为预设位置标识，该预设位置标识用于触发小区内的UE进行位置更新流程。
接入网设备将系统消息在小区内广播，目的是将网络接入层和非接入层的公共信息通知给小区内的UE，以便UE在发起呼叫之前了解网络的配置情况。系统消息通常是周期性广播的，UE在接入小区之前会读取系统消息，在UE接入小区后，通常情况下不会主动读取系统消息，因此，本实施例中接入网设备通过发送寻呼消息，触发小区内的UE主动读取系统消息。
本实施例中，接入网设备在发送系统消息之前，对系统消息进行了修改，系统消息包括一个主信息块(Master Information Block，简称MIB)和多个系统信息块(System Information Block，简称SIB)，其中MIB中包括小区最基本的物理层信息，SIB1中包括小区选择相关信息和其他SIB调度信息，其他SIB的内容这里不再一一介绍。本实施例中，接入网设备将系统消息中的SIB1中的小区位置标识更新为预设位置标识。该预设位置标识用于触发UE进行位置更新流程，UE只要读取到该预设位置标识，就会进行位置更新流程。该预设位置标识可以为系统预留的位置标识，预 留的位置标识用于特殊用途，正常的寻呼不会使用该预留的位置标识。该预设位置标识还可以为本发明新定义的一种位置标识。
本实施例中将系统消息中的小区位置标识更新为预设位置标识是为了触发空闲态UE进行位置更新流程，以便接入网设备能够根据位置更新流程定位到空闲态UE，实际上UE的位置并没有变化。正常情况下，如果UE的位置没有变化，UE保存的小区位置标识与系统消息中的小区位置标识是相同，UE不会进行位置更新流程。
需要说明的是，本实施例中接入网设备对空闲态UE进行定位是指接入网设备检测某一UE是否在接入网设备所在的小区内，并不是检测UE的具体位置。
在LTE系统中，小区位置标识为跟踪区域码(Tracking area code，简称TAC)，预设位置标识可以为系统预留的TAC。TAC用来标识一个跟踪区域，一个跟踪区域可以涵盖一个或者多个小区，跟踪区域是用来进行寻呼和位置更新的区域。
在UMTS中，小区位置标识为位置区域码(location area code，简称LAC)，预设位置标识可以为系统预留的LAC。LAC能够唯一地识别我国数字公共陆地移动网络(Public Land Mobile Network，简称PLMN)中每个位置区，是一个2字节16进制的二-十进制编码(Binary-Coded Decimal，简称BCD)，表示为L1L2L3L4(范围0000～FFFF，可定义65536个不同的位置区)，LAC在每个小区广播信道上的系统消息中发送。移动台在开机、插入用户身份识别(Subscriber Identity Module，简称SIM)卡或发现当前小区的LAC与其原来储存的内容不同时，通过国际移动用户识别码(International Mobile Subscriber Identification Number，简称IMSI)结合(IMSIAttach)或位置更新过程向网络通告其当前所在的位置区。网络储存每个UE的位置区，并作为将来寻呼该UE的位置信息。
可选的，该系统消息中还包括系统消息变更标识，该系统消息变更标识用于标识系统消息中的小区位置标识被更新了。当UE接收到系统消息后，UE先读取该系统消息变更标识，根据该系统消息变更标识确定系统消息是否被更新了。如果系统消息被更新了，则UE进一步读取系统消息中各SIB中的内容。如果系统消息没有被更新，则UE不会读取系统消息 中各SIB中的内容。
可选的，该系统消息变更标识可以为SIB1中的系统信息值标签(systemInfoValueTag)。systeminfovaluetag是取值为0-31，每当系统消息改变时systeminfovaluetag的值加1。UE收到系统消息后，从SIBI中读取systeminfovaluetag，将系统消息中的systeminfovaluetag的值和自身保存的systeminfovaluetag的值比较，如果系统消息中的systeminfovaluetag的值和自身保存的systeminfovaluetag的值不同，说明系统消息改变了，UE需要重新读取系统消息中其他SIB的内容。如果系统消息中的systeminfovaluetag的值和自身保存的systeminfovaluetag的值相同，说明系统消息没有改变，UE不需要读取系统消息中其他SIB的内容。当然，该系统消息变更标识也可以是本发明新定义的一种标识。
步骤104、空闲态UE根据读取指示信息接收系统消息，读取该系统消息中的小区位置标识，该系统消息中的小区位置标识为预设位置标识。
步骤105、空闲态UE根据该预设位置标识发起位置更新流程。
空闲态UE接收到系统消息后，获知系统消息中包括的小区位置标识被更新为了该预设位置标识，则发起位置更新流程。连接态UE接收到系统消息后，获知系统消息中包括的小区位置标识被更新为了该预设位置标识，则连接态UE可以发起位置更新流程，也可以不发起位置更新流程。
步骤106、接入网设备根据小区内的空闲态UE发起的位置更新流程，定位小区中的空闲态UE。
具体的，空闲态UE发起位置更新流程后，接入网设备会检测到空闲态UE发起的位置更新流程，根据空闲态UE发起的位置更新流程获取空闲态UE的临时用户标识(Temporary Mobile Subscriber Identity，简称TMSI)，进而确定出是哪个UE发起的位置更新流程，从而检测到空闲态UE的存在。接入网设备还可以根据空闲态UE发起的位置更新流程，获取到空闲态UE的接收信号强度等。接入网设备在获取空闲态UE的TMSI后，还可以进一步确定空闲态UE请求更新的小区的位置标识是否为预设位置标识，当UE确定空闲态UE请求更新的小区的位置标识为预设位置标识时，可以拒绝空闲态UE的位置更新操作。由于接入网设备拒绝了空闲态UE的位置更新操作，因此空闲态UE的位置并没有更新，该预设位 置标识不会增加到该空闲态UE的跟踪区列表中，后续在对该空闲态UE寻呼时，该空闲态UE的跟踪区列表中没有该预设位置标识，接入网设备不会根据该预设位置标识对UE进行寻呼。由于该预设位置标识并不是某个小区的位置标识，接入网设备根据该预设位置标识对该空闲UE进行寻呼时，无法寻呼到该空闲态UE，会导致寻呼资源的浪费。本实施例中通过决绝位置更新操作，避免了后续的无效寻呼导致的寻呼资源浪费的问题。
可选的，接入网设备在确定空闲态UE请求更新的小区位置标识为预设位置标识时，也可以继续执行位置更新流程，接入网设备将该预设位置标识添加到空闲态UE的跟踪区列表中，该种方式也不会影响UE正常的寻呼，但会导致寻呼资源的浪费。
本实施例中，如果连接态UE也发起了位置更新流程，接入网设备可以采用与空闲态UE同样的方法，拒绝连接态UE的位置更新流程，或者，进行正常的位置更新流程。
本实施例中，在位置更新流程中，接入网设备通过获取空闲态UE的TMSI和接收信号强度等，检测到空闲态UE的存在，即检测到空闲态UE位于接入网设备寻呼的小区内。接入网设备在定位到空闲态UE后，可以将UE的信息发送给服务锚点(Service Anchor，简称SVA)，SVA根据空闲态UE的信息进行以下操作：
(1)统计小区内用户数量：在室内或者室外特定区域，需要统计某一小区覆盖下的所有用户，现有的方法只能定位到连接态UE，无法定位到空闲态UE，因此，无法准确统计小区内用户的数量。通过本发明实施例的方法，基站可以定位到空闲态UE，SVA可以准确统计小区内用户数量(包括空闲态UE和连接态UE)。
(2)禁区闯入警告：当某用户带手机闯入了特定的禁区，手机处于空闲态时，现有的方法无法感知到空闲态手机的存在。采用本实施例的方法可以基站可以检测到空闲态UE的存在，并报告给SVA，由SVA向空闲态UE发出警告信息。
(3)节能：基站需要检测某个小区内是否有用户，以方便关闭室内覆盖设施，达到省电目的，现有技术中如果小区内没有连接态UE，只有 空闲态UE，由于基站无法检测到空闲态UE，基站会认为小区内没有用户，而关闭室内覆盖设施。后续如果该空闲态UE需要通信，会由于基站关闭了室内覆盖设置而无法通信，影响用户的正常使用。通过本发明实施例的方法，基站能够检测到小区内空闲态UE的存在，并报告给AVA，由SVA决定是否关闭室内覆盖设施。
本实施例，接入网设备通过将系统消息中的小区位置标识更新为预设位置标识，并通过寻呼消息通知小区内的UE系统消息有变更，以触发小区内的UE读取系统消息，感知到小区位置标识被更新，从而触发空闲态UE发起位置更新流程，接入网设备根据小区内的空闲态UE发起的位置更新流程，定位小区中的空闲态UE，从而实现了对空闲态UE的定位。
图2为本发明实施例二提供的对空闲态用户设备进行定位的方法的流程图，如图2所示，本实施例的方法可以包括以下步骤：
步骤201、接入网设备分别向小区内的空闲态UE发送寻呼消息，该寻呼消息中包括寻呼的空闲态UE的用户标识。
步骤202、空闲态UE接收寻呼消息。
步骤203、空闲态UE根据寻呼消息向接入网设备发送RRC连接建立请求。
步骤204、接入网设备拒绝该RRC连接建立请求，并根据该RRC连接建立请求定位空闲态UE。
本实施例的前提是接入网设备需要获取寻呼的空闲态UE的用户标识，该用户标识可以为空闲态UE的IMSI或TMSI，对于接入网设备来说可能只能获取到小区内从连接态转换到空闲态的UE的用户标识，对于移动到该小区内但没有接入过该小区的UE，接入网设备无法获取该UE的用户标识，从而无法发起对该UE的寻呼。
现有机制中，当小区内的某个UE从连接态转换为空闲态后，MME不会立即删除该UE的信息，而是将该UE的信息保存一段时间，因此，接入网设备可以从MME处获取该小区内空闲态UE的用户标识，该空闲态UE可能还驻留在该小区内，也可能已经离开该小区。
对于已经离开该小区的空闲态UE，接入网设备发送寻呼消息后，该空闲态UE不会接收到寻呼消息，也不会触发后续的RRC连接建立流程。
对于还驻留在该小区内的空闲态UE，接入网设备向该空闲态UE发送寻呼消息后，该空闲态UE会接收到寻呼消息，根据寻呼消息中携带的用户标识确定自己被寻呼了，进行正常的接入流程，即该空闲态UE发起RRC连接建立过程。对于该空闲态UE，由于此时接入网设备并没有下行数据要向该空闲态UE发送，如果为该空闲态UE建立RRC连接，会导致无线资源的浪费，因此，接入网设备可以拒绝该空闲态UE发起的RRC连接建立流程，从而避免无线资源的浪费。
对于移动到该小区但没有接入该小区的空闲态UE，由于该空闲态UE还没有接入过该小区，因此，接入网设备无法获取到该空闲态UE的用户标识，因此无法对该空闲态UE进行寻呼。
图3为本发明实施例三提供的接入网设备的结构示意图，如图3所示，本实施例提供的接入网设备包括：发送模块11和定位模块12。
发送模块11用于向小区内的UE发送寻呼消息，该寻呼消息中包括读取指示信息，该读取指示信息用于指示该小区内的UE读取系统消息。发送模块11还用于向小区内的UE发送系统消息，该系统消息中的小区位置标识为预设位置标识，该预设位置标识用于触发该小区内的UE进行位置更新流程。

可选的，该读取指示信息为BCCH修改信息。
可选的，接入网设备还包括更新模块，更新模块用于将该系统消息中的小区位置标识更新为该预设位置标识。

可选的，接入网设备还包括位置更新模块，位置更新模块用于拒绝空闲态UE的位置更新操作。
