控制用户设备接入高速移动工具通信网络的方法 技术领域
本发明涉及移动通信技术领域，尤其涉及一种控制用户设备接入高速移动工具通信网络的方法、核心网控制面节点设备、用户设备、基站及通信系统。
背景技术
高速移动工具在我国以及全球范围内发展迅速。例如，高速移动工具包括高速铁路火车(以下简称“高铁”)、磁悬浮列车、地铁等。以高铁为例，高铁运营里程已达到3万公里以上并且呈快速增长的趋势。伴随着高端人群大规模、长时间乘坐高速移动工具频繁流动的情况以及高速移动工具本身信息化建设的需求，高速移动工具的通信需求日益强烈。
然而，高速移动工具不同于常规的室内和室外移动通信场景，由于列车运行速度快，车体穿透损耗大，场景地形复杂多变等因数，使得现有的公网并不适用于为乘坐高速移动工具的用户提供服务。因此，建设一个专门为高速移动用户提供服务的网络的需求日渐突出。例如，目前已经有设备商和运营商开始规划和部署这样的高铁专用无线网络(以下简称“高铁专网”)。高铁专网覆盖高铁行进途中以及高铁火车站的站台附近。高铁火车站区域的小区部署如图1A所示。高铁火车站在高铁专网106覆盖下的专网小区包括室分小区和站台小区。其中，候车室102、进出站通道103都属于室分小区101。站台104属于站台小区。公网小区105覆盖火车站外的火车站广场。目前高铁网络规划将专网小区和公网小区独立部署。针对铁路线型覆盖的特点，高铁专网采取小区级联连续覆盖的方案，如图1B所示。在图1B的例子中，高铁的轨道区域被级联的专网小区111连续覆盖，同时公网小区115也覆盖了该高铁的轨道区域。
公网和高铁专网采用如下协同原则：
(1)在高铁线路大部分区域(如，高铁行进途中)，高铁专网小区和周边公网小区间不互配邻区关系。也就是说，专网小区只配专 网下的级联小区作为邻区，不配置公网作为邻区；公网小区也不配置专网小区作为邻区；
(2)在火车站的站台附近配置公网小区和专网小区为相互邻区关系，以让第一类型UE从公网小区(如图1A中的公网小区105)进入专网小区(如图1A中的公网小区101)或从专网小区进入公网小区。
在高铁行进途中，由于高铁专网小区和周边公网小区间无相互邻区关系，这样用户设备(英文：user equipment，简称：UE)在空闲态下无法从一种网络小区(如图1B中的公网小区115)执行小区重选到另一种网络小区(如图1A中的专网小区111)，在连接态时也无法执行切换流程切换到另一种网络小区。因此，在高速移动工具行进途中，当UE因异常原因脱离高速移动工具通信网络而接入公网后，现有技术无法使得该UE后续回到高速移动工具通信网络，影响了乘坐高速移动工具的用户的用户体验。

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。
本发明用于控制UE接入高速移动工具通信网络，使得属于乘坐高速移动工具通信网络的用户的UE在行进途中，即使因异常原因脱离高速移动工具通信网络而接入公网，也可重新回到高速移动工具通信网络。以下描述中，将乘坐高速移动工具(如，高铁)的用户所使用的UE简称为第一类型UE，而将非乘坐速移动工具的用户所使用的UE称为非第一类型UE。
本发明适用的高速移动工具通信网络是指为乘坐高速移动工具的用户提供通信服务的专用网络，其包括但不限于长期演进(英文：Long Term Evolution，简称：LTE)网络、全球移动通讯系统(英文：Global System of Mobile communication，简称：GSM)、或通用移动通讯系统(英文：Universal Mobile Telecommunications System，简称：UMTS)网络。在以上任一网络的场景下，通信系统至少包括核心网控制面节点设备、UE以及基站。在LTE网络下，核心网控制面节点设备包括但不限于移动性管理实体(英文：Mobility Management Entity，简称：MME)，基站包括但不限于演进型网络基站(英文：E-UTRAN NodeB，简称：eNodeB)。在GSM网络或UMTS网络下，核心 网控制面节点设备包括但不限于通用分组无线服务(英文：General Packet Radio Service，简称：GPRS)业务支撑节点(英文：Serving GPRS Support Node，简称：SGSN)或移动交换中心(英文：Mobile Switching Center，简称：MSC)，基站包括但不限于基站控制器(英文：base station controller，简称：BSC)或无线网络控制器(英文：radio network controller，简称：RNC)。在本发明中，公网和高速移动工具通信网络分别部署不同的接入网设备(如，eNodeB)。
以下将以高速移动工具为高铁，高速移动工具通信网络为高铁LTE网络为例进行描述。然而，本发明并不局限于此，高速移动工具包括但不限于高铁、磁悬浮、地铁，且本发明同样适用于GSM网络或UMTS网络。
例如，高铁专网覆盖的场景可分为高铁火车站以及高铁行进途中这两种。高铁火车站被站台小区和室分小区所覆盖，高铁行进途中也被级联的专网小区覆盖。此外，高铁火车站以及行进路线还都至少被高铁专网附近的公网小区部分覆盖。
图2所示为根据本发明一个实施例的控制UE接入高速移动工具通信网络的方法流程图。该方法由通信系统600中MME 630、UE 650以及eNodeB 640的协作执行。在图2的例子中，eNodeB 640为靠近高速移动工具通信网络(如，高铁专网)附近的公网的eNodeB。MME630为高速移动工具通信网络(如，高铁专网)专用的MME，或高速移动工具通信网络和公网共享的MME。如图2所示，该方法包括：
S601，第一UE 650接入速移动工具通信网络。例如，第一UE 650接入高铁专网。
例如，UE进站候车时，因火车站区域的室分小区和站台小区的信号比较好，绝大多数UE可以离开公网小区接入站台或室分小区，从而接入高铁专网，由专网eNodeB和专网MME为用户提供服务。又如，用户在进站时关机，在轨道区域才开机附着接入高铁专网，由专网eNodeB和专网MME为用户提供服务。
S602，MME 630确定UE 650为第一类型UE。
具体地说，MME 630可通过如下方式确定UE 650为第一类型UE：
(1)MME 630通过小区粒度来确定UE 650为第一类型UE。
当UE 650从高速移动工具通信网络的小区接入时，核心网控制面节点设备确定UE 650为第一类型UE。
MME 630配置有与高铁专网对应的专网小区的信息。专网小区的信息包括但不限于专网小区的小区标识。当UE 650进入连接态后，UE 650向MME 630发送NAS信令。MME 630可当根据基站上报的UE 650的小区信息识别出UE 650是否位于专网小区内。当MME 630识别出UE 650位于专网小区内，MME 630确定UE 650为第一类型UE。
(2)MME 630通过eNodeB粒度来确定UE 650为第一类型UE。
当UE 650从高速移动工具通信网络的基站接入时，核心网控制面节点设备确定UE 650为第一类型UE。
MME 630配置有与高铁专网对应的专网eNodeB的信息。专网eNodeB的信息包括但不限于专网eNodeB的标识或其IP地址。UE 650的所有信令是通过eNodeB发向MME 630的。因此，MME 630可根据eNodeB的信息识别服务UE 650的eNodeB是否属于专网eNodeB。当MME 630识别出服务UE 650的基站属于专网eNodeB，MME 630确定UE 650为第一类型UE。
(3)MME 630通过TA粒度来确定UE 650为第一类型UE。
当UE 650从高速移动工具通信网络的TA接入时，核心网控制面节点设备确定UE 650为第一类型UE。
在这种情况下，专网MME和公网MME可以分别部署，也可以是同一个MME设备下分别规划高铁TA和非高铁TA。若TA统一部署，可通过上述方式(1)或方式(2)来判断UE是否为第一类型UE。MME 630配置有高铁专网对应的专网TAI的信息。例如，专网TAI与公网TAI可通过TAI内部的TAC进行区分。
例如，当UE 650接入火车站的室分小区或站台小区后，因TA发生改变，UE 650经eNodeB向MME 630发起执行TAU流程、附着流程、业务请求流程、或切换流程等。UE 650或eNodeB通过TAU流程、附着流程、业务请求流程或切换流程向MME 630上报UE 650的当前所在TAI或目标TAI。MME 630可根据UE 650或eNodeB上报的当前所 在TAI或目标TAI识别该当前所在TAI或目标TAI是否属于专网TAI。当MME 630识别出UE 650或eNodeB上报的当前所在TAI或目标TAI属于专网TAI，MME 630确定UE 650为第一类型UE。
据此，MME 630为该UE分配临时标识。临时标识携带一个用于指示该UE为第一类型UE的序列。
例如，MME 630为接入高铁专网的UE 650分配第一临时标识，第一临时标识携带第一序列，该第一序列用于指示UE 650为第一类型UE。MME共享场景下，MME 630还为接入公网的第二UE分配第二临时标识(图中未示出)，该第二临时标识携带第二序列，该第二序列用于指示该UE为非第一类型UE。例如，第二UE包括在火车站没有接入到站台室分小区而接入了与室分小区重叠的公网小区的UE，或者接入了站台附近的其他公网小区的UE。
在LTE网络中，临时标识包括但不限于全局唯一临时标识(英文：Globally Unique Temporary Identity，简称：GUTI)，其包含的序列包括但不限于移动性管理实体编码(英文：Mobility Management Entity Code，简称：MMEC)。因此，MME 630为第一UE分配的第一临时标识GUTI携带第一序列，该第一序列为专网MMEC，MME 630为第二UE分配的第二临时标识GUTI携带第二序列，该第二序列为公网MMEC。通过不同的MMEC，MME 630可区分一个UE是否为第一类型UE。
当本发明应用于2G网络或3G网络时，临时标识包括但不限于CS域的临时移动用户标识码(英文：Temporary Mobile Subscriber Identity，简称：TMSI)以及PS域的分组临时移动用户标识码(英文：Packet Temporary Mobile Subscriber Identity，简称：P-TMSI)。其包含的序列包括但不限于网络资源标识(英文：Network Resource Identifier，简称：NRI)。通过不同的NRI，核心网控制面节点设备SGSN或MSC可区分一个UE是否为第一类型UE。
举例来说，MMEC为长度为8个bit序列，可通过将MMEC中的某一位或多位进行设置，来区分该MMEC为专网MMEC还是公网MMEC，从而区分具有该MMEC的UE是否为第一类型UE。例如，若MMEC的最高位被置为1，则该MMEC为专网MMEC，对应第一类型UE；若MMEC 的最高位被置为0，则该MMEC为公网MMEC，对应非第一类型UE。
S603，MME 630向第一UE 650发送第一GUTI。第一GUTI中携带专网MMEC。相应地，第一UE 650接收MME 630发送的第一GUTI，第一GUTI携带用于指示所述第一UE为第一类型UE的专网MMEC。在LTE网络中，MME 630向第一UE发送第一GUTI。具体地，MME 630向第一UE发送GUTI重分配消息，其中携带第一GUTI；或者，所述MME 630向第一UE发送附着接受消息，其中携带第一GUTI；或者，所述MME 630向第一UE发送跟踪区更新接受消息，其中携带第一GUTI。
当本发明应用于2G网络或3G网络时，MSC/SGSN向第一UE发送第一TMSI/P-TMSI，具体地，可以通过向第一UE发送TMSI/P-TMSI重分配消息，其中携带第一TMSI/P-TMSI；或者，MSC/SGSN通过向第一UE发送附着接受消息，其中携带第一TMSI/P-TMSI；或者，MSC/SGSN通过向第一UE发送位置区/路由区更新接受消息，其中携带第一TMSI/P-TMSI。
因此，在高铁后续行进过程中，MME 630和eNodeB 640都可根据第一序列(专网MMEC)判断该UE为第一类型UE。若该第一UE 650因异常原因误接入到公网，eNodeB 640可根据专网MMEC，指示该UE重定向至高铁专网的小区。也就是说，专网MMEC用于该UE误接入的公网eNodeB来判断将该UE为第一类型UE，从而指示该UE重定向至高铁专网小区。
S604，实际属于高铁专网的第一UE 650在行进沿线上误接入了公网。该第一UE已接收由MME 630分配的用于指示其为第一类型UE的专网MMEC。
S605，第一UE 650向eNodeB 640发送无线资源控制(英文：Radio Resource Control，简称：RRC)建立请求消息。该RRC建立请求消息携带专网MMEC。
S606，eNodeB 640判断RRC建立请求消息中是否携带专网MMEC。
例如，eNodeB 640判断RRC建立请求消息中的序列MMEC的最高位是否被置为1。若RRC建立请求消息中的序列MMEC的最高位被置为1，则eNodeB 640判断RRC建立请求消息中携带专网MMEC。否则， eNodeB 640判断RRC建立请求消息中没有携带专网MMEC。
S607，若eNodeB 640判断RRC建立请求消息中携带专网MMEC，则向UE发送RRC连接释放(RRC Connection Release)消息，RRC Connection Release消息中的redirected Carrier Info用于指示UE 220重定向回高铁专网。据此，UE通过重定向接入高铁专网。
因此，本发明通过核心网控制面节点设备MME为第一类型UE和非第一类型UE分配不同的临时标识，来对第一类型UE和非第一类型UE加以区分，从而保证了第一类型UE能够进入高铁专网，并一直驻留于专网，即使发生异常情况误接入公网，也能很快被返回至专网。因此，为第一类型UE提供了专用的网络资源，从而提升了第一类型UE服务体验。
可选的，核心网控制面节点设备为UE分配临时标识并下发至UE后，该方法还可包括以下步骤S608、S609、S610中的至少一项。步骤S608和S610由高铁专用的核心网控制面节点设备(如，MME 630)或共享MME来执行，步骤S609由公网专用的核心网控制面节点(如，MME 632)或共享MME来执行。
S608，MME 630为第一UE更新专网MMEC。
例如，在LTE网络下，对于已经被分配了专网MMEC的第一UE，因高铁列车的高速移动，会产生移动性管理流程如TAU流程或切换流程。
以LTE网络的环境为例。在高铁列车移动过程中，UE经专网eNodeB发送TAU请求消息或切换请求消息给MME 630，MME 630若识别出该UE处于专网小区中，则接受该UE的TAU请求或切换请求，发送响应消息。例如，MME可通过判断该UE是否携带第一序列(如，专网MMEC)，或者，TAU请求消息或切换请求消息来源于专网eNodeB，来识别该UE是否处于专网小区中。
当MME 630已识别出该UE处于专网小区中，进一步判断MME是否改变。例如，核心网设备MME的覆盖范围相对较大，当高铁列车行进距离较短，如从江苏至上海，行进过程中始终由同一个MME覆盖。如果列车从江苏行进到山东，则行进途中会改变MME。当覆盖UE的 MME改变后，新的MME为该UE重新分配一个新的临时标识GUTI，其中包含一个新的专网MMEC。例如，MMEC为长度为8个bit的序列。最高位被置为1的序列MMEC为专网MMEC，对应第一类型UE。例如，在第一MME的覆盖下，第一MME为该UE分配的专网MMEC为10000000，当该UE转由第二MME覆盖时，第二MME为该UE分配的专网MMEC为10000001。
对于未被分配专网MMEC的第一类型UE(如，第三UE)因异常原因接入公网的场景，可通过步骤S609使第一类型UE接入高铁专网。具体的，第三UE包括实际应接入高铁专网，但在火车站台因异常原因(如站台专网拥塞)没有接入专网，而被误接入了公网并分配了公网MMEC的UE；或者，第三UE还包括进入轨道区域才开机的第一类型UE，开机附着时优先选择了之前驻留的频点进行接入，从而被误接入了公网并分配了公网MMEC的UE。
可选的，S609可通过S609a或S609b来实现。
S609a(图中未示出)，第三UE通过开口小区接入高铁专网。开口小区的设置与图3B中的描述相同，在此不再赘述。在第三UE接入高铁专网后，MME 630确定第三UE为第一类型UE，并为其分配专网MMEC。MME 630确定第三UE为第一类型UE及分配专网MMEC的步骤与步骤S602相同，在此不再赘述。
S609b，MME632确定第三UE为第一类型UE，并为第三UE分配专网MMEC。接着，MME 632向服务UE的公网eNodeB发送通知消息，该通知消息用于告知服务UE的公网eNodeB将该含专网MMEC的第三UE迁回专网，具体可以通过重定向或者切换方式将UE迁回专网。
举例来说，MME 632需要预先配置靠近高铁专网的公网eNodeB的信息。当第三UE处于连接态下，步骤S609b具体包括：
MME 632判断服务该第三UE的eNodeB是否靠近高铁专网的公网eNodeB，并且服务的eNodeB的变换频率是否高于预设值。若MME 632判断服务该第三UE的eNodeB是靠近高铁专网的公网eNodeB，并且服务的eNodeB的变换频率高于预设值，则MME 632为该第三UE重分配临时标识GUTI，该临时标识GUTI携带专网MMEC。
或者，MME732还可以接收公网eNodeB发送的通知消息，该通知消息用于告知公网MME该第三UE为第一类型UE。例如，服务UE的靠近高铁沿线的公网eNodeB可根据测速算法(如多普勒频偏算法)，判断出该第三UE在高速移动，从而确定连接态的第三UE为第一类型UE。在公网eNodeB确定连接态的该第三UE为第一类型UE后，向公网MME发送通知消息，进而使得公网MME确定该第三UE为第一类型UE。
当第三UE处于空闲态下，步骤S609b具体包括：
当第三UE发起TAU流程时，MME 632接收TAU请求。MME 632根据预先配置的靠近高铁专网的公网eNodeB的信息，判断该TAU请求消息是否来自靠近专网的公网eNodeB。若MME 632判断该TAU请求消息来自于靠近专网的公网eNodeB，后续MME 632每隔一定时间寻呼一次第三UE。如果发现寻呼响应消息都来自靠近专网的公网eNodeB，并且eNodeB的变换频率高于预设值，则为UE重分配GUTI，其中携带专网MMEC。接着，MME 632向服务UE的公网eNodeB发送通知消息，该通知消息用于告知将该含专网MMEC的UE迁回至专网，具体可以通过重定向或者切换方式将用户迁回专网。因此，通过步骤S609，可使得一开始在火车站站台没能接入专网或者在火车上开机附着进公网的UE能够在高铁列车行进过程中接入专网，进一步保证了所有的第一类型UE都能接入专网，提升了第一类型UE的用户体验。
S610，MME 630确定误接入专网的第四UE为非第一类型UE，并据此为第四UE分配公网MMEC。
第四UE包括实际应属于公网用户，但却误接入专网并被分配了专网MMEC的UE。例如，高铁沿线附近UE开机附着时可能会接入专网，或者公网用户发生异常经网络重选也可能接入到专网。通过步骤S610，可将此类UE踢出高铁专网，转变为公网用户。
举例来说，当第四UE处于空闲态下，步骤S610具体包括：
如果MME发现UE在一段时间内一直处于同一个TA，例如，UE上报的TAI保持不变，或者，UE在一段时间内TA改变的范围小于预设值，那么MME就为UE重分配GUTI，其中携带公网MMEC。预设值的设定可考虑高铁的平均速度等因素。接着，MME 630向专网eNodeB发送通知消 息，该通知消息用于告知专网eNodeB将该第四UE迁出到公网，具体迁出方式可以是切换或重定向等。
当第四UE处于连接态下，步骤S610具体包括：
如果MME发现一段时间内服务于UE的eNodeB并没有改变，或者，服务UE的eNodeB变换频率小于预设值，或者，由第四UE或服务第四UE的eNodeB的上报的小区信息没有改变，或者，上报的小区信息变换频率小于预设值，则重新为第四UE分配GUTI，其中携带公网MMEC。预设值的设定可考虑高铁的平均速度等因素。接着，MME向专网eNodeB发送通知消息，该通知消息用于告知专网eNodeB将该第四UE迁出到公网，具体迁出方式可以是切换或重定向等。
因此，通过执行步骤S610，可对误接入高铁专网的非第一类型UE进行识别，并能将非第一类型UE踢出专网，从而避免大量的非第一类型UE入侵高铁专网并长时间占用专网资源，避免专网拥塞。
当高铁列车到达终点站台，对于从火车站离开的UE，带有专网MMEC的用户离开高铁专网接入公网，公网eNodeB和MME接受用户的接入请求，站台附近的公网eNodeB不做重定向操作，从而防止UE出站时在公网和专网之间产生乒乓甚至脱网。
图3所示为根据本发明另一个实施例的控制UE接入高速移动工具通信网络的方法流程图。图3将结合图2进行描述。图3和图2标号相同的步骤用于执行相同或类似的功能，在此不再赘述。
S702，在第一UE 650接入高速移动工具通信网络后，MME 630确定UE 650为第一类型UE，并据此为该UE分配临时标识。临时标识携带一个用于指示该UE为第一类型UE的序列。图3中MME 630确定UE 650为第一类型UE的具体步骤与图2中的步骤S602不同。
具体来说，当第一UE通过高速移动工具通信网络的车站区域接入后，步骤702包括步骤702a。
S702a，MME 630确定UE 650为第一类型UE。
具体来说，MME 630可通过小区、eNodeB、TA这三个不同的粒度来确定UE 650为第一类型UE：
(1)MME 630通过小区粒度来确定UE650为第一类型UE。
当UE 650从高速移动工具通信网络的车站区域的小区接入时，核心网控制面节点设备确定UE 650为第一类型UE。
例如，MME 630配置有火车站区域内与高铁专网对应的专网小区的信息。专网小区的信息包括但不限于专网小区的小区标识。当UE 650进入连接态后，UE 650向MME 630发送NAS信令。MME 630可当根据基站上报的UE 650的小区信息识别出UE 650是否位于专网小区内。当MME 630识别出UE 650位于专网小区内，MME 630确定UE 650为第一类型UE。
(2)MME 630通过eNodeB粒度来确定UE 650为第一类型UE。
当UE 650从高速移动工具通信网络的车站区域的基站接入时，核心网控制面节点设备确定UE 650为第一类型UE。
例如，MME 630配置有火车站区域内与高铁专网对应的专网eNodeB的信息。专网eNodeB的信息包括但不限于专网eNodeB的标识或其IP地址。UE 650的所有信令是通过eNodeB发向MME 630的。因此，MME630可根据eNodeB的信息识别服务UE 650的eNodeB是否属于专网eNodeB。当MME 630识别出服务UE 650的基站属于专网eNodeB，MME 630确定UE650为第一类型UE。
(3)MME 630通过TA粒度来确定UE 650为第一类型UE。
当UE 650从高速移动工具通信网络的车站区域的TA接入时，核心网控制面节点设备确定UE 650为第一类型UE。
在这种情况下，专网MME和公网MME可以分别部署，也可以是同一个MME设备下分别规划高铁TA和非高铁TA。若TA统一部署，可通过上述方式(1)或方式(2)来判断UE是否为第一类型UE。MME 630配置有火车站区域内与高铁专网对应的专网跟踪区标识(英文：Tracking Area Identity，简称：TAI)的信息。例如，专网TAI与公网TAI可通过TAI内部的跟踪区编码(英文：Tracking Area Code，简称：TAC)进行区分。
当UE 650接入火车站的室分小区或站台小区后，因TA发生改变，UE 650经eNodeB向MME 630发起跟踪区更新(英文：Tracking Area Update，简称：TAU)流程、附着(attach)流程、业务请求(service  request)流程、或切换流程等。UE 650或eNodeB通过TAU流程、附着流程、业务请求流程或切换流程向MME 630上报UE 650的当前所在TAI或目标TAI。MME 630可根据UE 650或eNodeB上报的当前所在TAI或目标TAI识别该当前所在TAI或目标TAI是否属于专网TAI。当MME 630识别出UE 650或eNodeB上报的当前所在TAI或目标TAI属于专网TAI，MME 630确定UE 650为第一类型UE。
例如，开机的空闲态UE 650从火车站广场进入火车站时，会因所处TA发生改变而向MME 630发起TAU流程。当UE 650向MME 630发起TAU流程，服务于UE 650的eNodeB向MME 630上报的UE当前所在的TAI属于火车站区域的专网TAI。据此，MME 630确定UE 650为第一类型UE。又例如，正在进行业务的UE 650从火车站外广场进入火车站，可能会发生业务的切换流程。此时，MME 630接收到原网络eNodeB和原网络MME发送的目标TAI。MME 630判断该目标TAI属于火车站区域的专网TAI，从而确定UE 650为第一类型UE。MME 630根据在其他流程中上报的TAI确定UE 650为第一类型UE与以上描述类似，在此不再赘述。
当第一UE通过高速移动工具通信网络的轨道区域接入后，步骤702包括步骤702b。
S702b，MME 630确定UE 650为第一类型UE。
具体来说，MME 630可通过小区、eNodeB、TA这三个不同的粒度来确定UE 650为第一类型UE：
(1)MME 630通过小区粒度来确定UE 650为第一类型UE。
当所述UE从所述通信网络的轨道区域的第一小区移动到所述通信网络的轨道区域的第二小区，并且所述UE从所述第二小区接入所述通信网络时，所述核心网控制面节点设备确定所述UE为第一类型UE。
例如，MME 630配置有轨道区域内与高铁专网对应的专网小区的信息。专网小区的信息包括但不限于专网小区的小区标识。MME 630可当根据基站上报的UE 650的多个小区信息识别出UE 650是否位于专网小区内。当MME 630识别出UE 650在多个专网小区内移动，MME630确定UE 650为第一类型UE。
(2)MME 630通过eNodeB粒度来确定UE 650为第一类型UE。
当所述UE从所述通信网络的轨道区域的第一基站移动到所述通信网络的轨道区域的第二基站，并且所述UE从所述第二基站接入所述通信网络时，所述核心网控制面节点设备确定所述UE为第一类型UE。
例如，MME 630配置有轨道区域内与高铁专网对应的专网eNodeB的信息。专网eNodeB的信息包括但不限于专网eNodeB的标识或其IP地址。UE 650的所有信令是通过eNodeB发向MME 630的。因此，MME 630可根据eNodeB的信息识别服务UE 650的多个eNodeB是否属于专网eNodeB。当MME 630识别出服务UE 650的多个基站属于专网eNodeB，MME 630确定UE 650为第一类型UE。
(3)MME 630通过TA粒度来确定UE 650为第一类型UE。
当所述UE从所述通信网络的轨道区域的第一跟踪区TA移动到所述通信网络的轨道区域的第二跟踪区TA，并且所述UE从所述第二跟踪区TA接入所述通信网络时，所述核心网控制面节点设备确定所述UE为第一类型UE
在这种情况下，专网MME和公网MME可以分别部署，也可以是同一个MME设备下分别规划高铁TA和非高铁TA。若TA统一部署，可通过上述方式(1)或方式(2)来判断UE是否为第一类型UE。MME 630配置有轨道区域内与高铁专网对应的专网TAI的信息。例如，专网TAI与公网TAI可通过TAI内部的TAC进行区分。当UE 650接入轨道区域专网后，可能因需要发起业务流程或者因移动而触发TAU流程或者切换流程。UE 650或服务于其的eNodeB通过TAU流程、业务请求流程或切换流程等向MME 630上报UE 650的源TAI和目标TAI或，新TAI和旧TAI。MME 630可根据UE 650或eNodeB上报的源TAI和目标TAI，或，新TAI和旧TAI，识别源TAI和目标TAI，或，新TAI和旧TAI是否都属于专网TAI。当MME 630识别出UE 650上报的源TAI和目标TAI都属于专网TAI，MME 630确定UE 650为第一类型UE。
(4)所述核心网控制面节点设备(如，MME 630)接收专网基站发送的通知消息，所述通知消息用于指示所述UE为第一类型UE，所述 核心网控制面节点设备根据所述通知消息确定所述UE为第一类型UE。
例如，服务UE 650的专网eNodeB可根据测速算法(如多普勒频偏算法)，判断出该UE 650在高速移动，从而确定连接态UE 650为第一类型UE。在专网eNodeB确定连接态UE 650为第一类型UE后，向MME 630发送通知消息，进而使得MME 630确定该UE650为第一类型UE。
可选地，当MME 630识别出第一UE已配置有专网MMEC，则MME 630确定第一UE为第一类型UE。例如，UE 650已经在火车站区域接入过专网且被分配了含有专网MMEC的GUTI，当UE 650随火车移动进入轨道区域时，UE 650向MME 630发送的接入/业务请求消息中携带含有专网MMEC的GUTI，MME 630通过上报的专网MMEC可识别UE 650为第一类型UE。此种情况下，MME 630针对该UE只需沿用原专网MMEC或更新专网MMEC。
类似地，当MME 630执行完步骤S702，确定该UE为第一类型UE后，才为该UE分配专网MMEC。但是，对于在轨道区域经专网eNodeB向MME 630发起接入请求(如TAU请求、附着请求、切换请求)的UE，在MME 630确定该UE为第一类型UE前，MME 630先接受该UE的接入请求，允许UE接入专网。
类似地，如步骤S603至S607的描述，在MME 630确定第一UE为第一类型UE，并为该第一UE分配携带专网MMEC的第一GUTI后，MME 630向第一UE 650发送第一GUTI。第一GUTI中携带专网MMEC。相应地，第一UE 650接收MME 630发送的第一GUTI。因此，当第一UE 650因异常原因误接入到公网，eNodeB 640可根据专网MMEC，指示该UE重定向至高速移动工具通信网络的小区。
在图3的例子中，可选的，MME 630为UE分配临时标识并下发至UE后，该方法还可包括以下步骤S608、S709、S710中的至少一项。S608在此不再赘述。
对于未被分配专网MMEC的第一类型UE(如，第三UE)因异常原因接入公网的场景，可通过步骤S709使第一类型UE接入高速移动工具通信网络。
可选的，S709可通过S709a或S709b来实现。
S709a(图中未示出)，第三UE通过开口小区接入高铁专网。
该开口小区配置了周边的高铁专网小区作为邻区，并且设置专网频点优先级高于公网频点优先级，从而使得UE经过该开口小区时能够向专网发起切换或重选流程，从而接入高铁专网。开口小区一般设在高铁途中位置空旷、公网用户少的区域，因而可避免大量的公网用户也被迁移进入专网。
在第三UE接入高铁专网后，MME 630确定第三UE为第一类型UE，并为其分配专网MMEC。MME 630确定第三UE为第一类型UE及分配专网MMEC的步骤与步骤S702b相同，在此不再赘述。
步骤S709b与步骤S609b相同，在此不再赘述。
步骤S710用于将第四UE迁出高铁专网。第四UE包括实际应属于非第一类型UE，但却误接入专网并被分配了专网MMEC的UE。例如，高铁沿线附近UE开机附着时可能会接入专网，或者非第一类型UE发生异常经网络重选也可能接入到专网。通过步骤S710，可将此类UE踢出高铁专网，转变为非第一类型UE。可选的，步骤S710包括步骤S710a或S710b。
S710a,MME 630确定误接入专网的第四UE为非第一类型UE，并据此为第四UE分配公网MMEC。
例如，步骤S710a可通过步骤S610中的描述来确定第四UE为非第一类型UE，在此不再赘述。
S710b，专网eNodeB测量连接态UE的速度，确定速度低于预设值且无专网MMEC的UE为非第一类型UE，并据此将该UE迁出高铁专网，例如，通过切换方式将该UE迁出高铁专网。
