Description

一种接入控制方法、终端及接入网设备 技术领域
本申请涉及通信技术领域，尤其涉及一种接入控制方法、终端及接入网设备。
背景技术
随着通信技术的发展，终端可以随时随地地接入移动通信网络，获取通信服务。然而，当终端在高铁、磁悬浮和地铁等高速移动工具上使用时，由于高速移动过程中终端对小区的切换和重选不及时，并且列车的材质为钢铁，会造成电磁信号的穿透损耗，最终导致终端接收到的信号较差，影响用户的使用体验。
为了满足用户的使用体验，运营商会在铁路沿线铺建专门针对位于高速移动工具的终端的专用网络，为位于高速移动工具的终端提供专用小区。该专用小区的信号质量优于针对其他终端的公共网络的信号质量，因而能够提供更好的覆盖来补偿车厢造成的穿透损耗。然而，由于空闲态终端根据信号质量进行小区选择，导致大量铁路附近的其他终端驻留在上述专用小区上，一旦空闲态的终端在该专用网络上建立无线资源控制(RRC)连接进入连接态后，使用该网络进行通信，会造成该专用小区拥塞，降低高速移动工具上的用户的使用体验。
因此，如何避免非高速移动工具上的终端与高速移动工具的终端的专用小区保持或建立无线资源控制连接，成为一个亟待解决的问题。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
本申请实施例提供一种接入控制方法、终端及基站，可以有效辨别位于高速移动工具的终端(高速移动工具停站时)和非高速移动中的终端，避免非高速移动中的终端与高速移动工具的终端的专用小区保持或建立无线资源控制连接所造成的专用小区拥塞问题。
在本申请的实施例中所涉及的位于高速移动工具的终端的专用小区，是指运营商为乘坐高速移动工具的用户提供通信服务的专用网络下的专用小区，上述专用网络包括但不限于第五代移动通信技术(5th-Generation，5G)系统、长期演进(Long Term Evolution，LTE)网络、全球移动通讯系统(Global System of Mobile communication，GSM)、或通用移动通讯系统(Universal Mobile Telecommunications System，UMTS)网络。其中，5G系统可以是新无线(New Radio，NR)系统。
以下将以接入网设备为基站为例进行描述。然而，本申请并不局限于此，本申请实施例中所述的接入网设备包括NR系统中的基站设备，例如gNB、传输点(trasmission point，TRP)，或者由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的基站设备，CU也可以称为控制单元(control unit)。当长期演进(long term evolution，LTE)系统中的基站设备，即演进型节点B(evolved nodeB，eNB)可以连接5G核心网(5G-Core，5G CN)时，LTE eNB也可以称为eLTE eNB。具体地，eLTE eNB是在LTE eNB基础上演进的LTE基站设备。所述接入网设备还可以是接入点(access point，AP)，或者其他具有与终端及核心网通信能力的网络设备，本申请实施例对接入网设备的类型不做特别限定。此外，GSM系统中的基站设备为基站收发台(BTS，Base Transceiver Station)或者基站控制器(Base Station Controller，BSC)；UMTS中的基站设备为节点B(Node B)或无线网络控制器(Radio Network Controller，RNC)。
本申请实施例所涉及到的终端可以包括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，以及各种形式的用户设备(user equipment，UE)，移动台(mobile station，MS)，终端设备(terminal equipment)等。
以下将以高速移动工具为高铁，位于高速移动工具的终端的专用小区为高铁LTE专用小区(简称高铁专用小区)为例进行描述。然而，本申请并不局限与此，高速移动工具包括但不限于高铁、磁悬浮列车、地铁、高速公路上的交通工具等各类移动速度可以达到对应阈值以上的移动工具。
请参见图1A，图1A是本申请实施例公开的一种接入控制方法的流程示意图。其中，该流程包括以下步骤：
101、目标基站接收指示信息。
本申请实施例可应用于连接态的终端由源基站切换到目标基站的应用场景。
其中，上述连接态指终端在空口的无线资源控制(Radio Resource Control，RRC)状态。终端在空口有两种无线资源控制状态：空闲态(IDLE)和连接态(Connected)。当终端需要进行业务时，需要建立与网络的连接，即从空闲态转到连接态，然后进行业务数据 的传输。空闲态的终端会在一个小区进行驻留，由于终端的移动性，会进行小区重选来变更驻留的小区。空闲态的终端，当有下行数据到达或上行数据到达时，终端会在当前驻留的小区上发起新的RRC连接建立以进入连接态。处于连接态的终端如果长时间没有数据传输，则基站给终端发送RRC连接释放消息，从而终端进入空闲态。
本申请实施例中，步骤101中的指示信息，可以包含在使目标基站确定终端是否为高速移动中的终端的专用消息中，也可包含在其他消息中，举例来说，该指示信息可承载于源基站发送给目标基站的，用以请求目标基站的小区允许终端接入的切换请求消息。
可选地，当基站分为CU与DU时，即基站的功能由CU和DU实现，则目标基站通过CU从源基站接收所述指示信息。此外，当目标基站或源基站接收终端的信息或者向终端发送信息时，终端与DU间进行直接通信，DU将接收到的终端的信息发送给CU进行处理；或者DU将CU下发的消息传输给终端。
102、所述目标基站根据所述指示信息确定终端为高速移动中的终端。
本申请实施例中，目标基站可以解析接收到的指示信息，并根据指示信息的内容确定终端是否为高速移动中的终端。
作为一种可选的实施方式，上述指示信息可以包含指示终端为高速移动中的终端的标识。该标识可以是二进制比特值，例如，“0”表示终端为低速的终端，“1”表示终端为高速的终端；该标识还可以是布尔值，“FALSE”表示终端为低速的终端，“TRUE”表示终端为高速的终端；该标识还可以是特定的信元，指示信息携带该信元时表示终端为高速的终端，不携带该信元时表示终端为低速的终端。目标基站在解析指示信息后，获取到上述标识，即可确认终端是否为高速移动中的终端。
作为一种可选的实施方式，上述指示信息可以包含终端最近进行的最多N次切换操作中(举例来说，最近进行的15次切换操作)，终端切换至的历史小区的标识、类型和保持无线资源控制连接的时间。举例来说，若终端最近进行了两次切换操作，两次切换完成后分别保持无线资源控制连接在A小区和B小区，则A小区与B小区为上述历史小区。
目标基站根据上述小区的标识、类型和保持无线资源控制连接的时间计算终端的移动速度，并根据终端的移动速度确定终端是否为高速移动中的终端。上述类型可以根据小区的覆盖范围来进行区分，举例来说，若小区的类型为微小区，其覆盖半径可以为30m至300m之间，则结合小区的类型和在该小区的保持无线资源控制连接的时间，可以计算得出终端在该小区保持无线资源控制连接时的移动速度。
作为一种可选的实施方式，所述指示信息包含终端最近进行的最多N次切换操作中，切换至的小区的属性，上述小区的属性用于表示小区是否为高铁专用小区，目标基站根据上述小区的属性可以推断出终端位于高铁上，从而确定终端为高速移动中的终端。
103、所述目标基站执行计时操作。

在上述实施方式之中，若目标基站为高铁站台附近的基站，则可以将上述预设时间阈值设置为高铁停站时长；因此，当终端为高铁上的终端时，若高铁在站台停站，目标基站可以等待到高铁停站时间之后再对终端的移动速度进行计算，从而避免将终端确定为非高速移动中的终端而中断终端与高铁专用小区的连接或者拒绝终端接入高铁专用小区。需要说明的是，上述时间阈值可不局限于高铁停站时长，其可以根据具体情况进行相应调整。
105、当所述终端的移动速度小于预设速度阈值时，所述目标基站拒绝所述终端接入所述目标基站的小区，所述目标基站的小区为位于高速移动工具的终端的专用小区。

116、目标基站在定时器超时之后，计算当前终端的移动速度。
117、若当前终端的移动速度大于等于预设速度阈值，则目标基站保持终端与本基站的高铁专用小区的连接；若当前终端的移动速度小于预设速度阈值，则目标基站中断终端与本基站的高铁专用小区的连接。

121、源基站向目标基站发送用以将终端切换至目标基站的高铁专用小区的切换请求消息；其中，该切换请求消息中携带指示信息(指示信息的具体内容可参考步骤102中的相关描述)，用以确定终端是否为高速移动中的终端。

133、目标基站在定时器超时之后，计算当前时刻终端的移动速度。
134、若当前终端的移动速度小于预设速度阈值，则目标基站向源基站反馈与切换请求消息对应的应答消息以拒绝终端接入；源基站接收到该应答消息之后，不执行向终端发送切换消息的操作。
由此可见，实施图1A所描述的方法，可以有效辨别位于高速移动工具的终端，包括高速移动工具停站时仍然处于高速移动工具上的终端，以及非高速移动中的终端，避免非高速移动中的终端接入在上述专用小区造成专用小区拥塞；并避免位于高速移动工具的终端被确定为非高速移动中的终端而被中断或拒绝与专用小区的连接。
请参见图2，图2为本申请实施例公开的另一种接入控制方法的流程示意图，该方法包括但不限于如下步骤：
201、终端接收第一小区所在基站发送的指示信息；所述指示信息包含指示所述第一小区是否属于预设区域的标识；
202、当所述指示信息指示所述第一小区属于所述预设区域，执行步骤203；当所述指示信息指示所述第一小区不属于所述预设区域时，执行步骤204。
本申请实施例可应用于空闲态的终端进行小区重选的应用场景。
其中，上述空闲态指终端在空口的无线资源控制状态(Radio Resource Control，RRC)。空闲态的终端会在一个小区进行驻留，由于终端的移动性，会进行小区重选来变更驻留的小区。空闲态的终端，当有下行数据到达(网络触发)或上行数据到达(终端触发)时，终端会在当前驻留的小区上发起新的RRC连接建立以进入连接态。处于连接态的终端如果长时间没有数据传输，则基站给终端发送RRC连接释放消息，从而终端进入空闲态。
本申请实施例中，上述预设区域可为高铁站台、磁悬浮站台、地铁站台或高速公路服务区等，本申请实施例不做限定。现以预设区域为高铁站台为例进行说明。
203、所述终端在接收到所述指示信息前为高速移动中的终端时，将所述终端确定为高速移动中的终端；之后执行步骤205。
204、终端计算所述终端的移动速度，根据所述计算的结果确定所述终端是否为高速移动中的终端；若所述终端是高速移动中的终端，则执行步骤205；若所述终端不是高速移动中的终端，则执行步骤206。
205、终端选择到第一小区以进行驻留；所述第一小区为高铁专用小区。
206、所述终端选择第二小区以进行驻留；所述第二小区为除高铁专用小区以外的公共小区。
由此可见，若终端为高铁上的终端，高铁在第一小区所属的高铁站台区域停站，若终端对自身进行速度计算，则可能将自身确定为非高速移动中的终端，而无法选择驻留在高铁专用网络。因此，第一小区所在基站可向终端发送指示信息以说明自身属于高铁站台区域，终端当前不对自身进行速度计算，直接按照停站前的状态将自身确定为高速移动中的终端，从而可以驻留在第一小区(即高铁专用小区)。
请参见图3，图3为本申请实施例公开的另一种接入控制方法的流程示意图，该方法包括但不限于如下步骤：
301、终端接收第一小区所在基站发送的指示信息；所述指示信息包含指示所述终端是 否进行速度计算的标识；
302、当所述指示信息指示所述终端不进行速度计算，执行步骤303；当所述指示信息指示所述终端进行速度计算时，执行步骤304。
本申请实施例可应用于空闲态的终端进行小区重选的应用场景。
303、所述终端在接收到所述指示信息前为高速移动中的终端时，将所述终端确定为高速移动中的终端；之后执行步骤305。
304、终端对所述终端进行速度计算，根据所述速度计算的结果确定所述终端是否为高速移动中的终端；若所述终端是高速移动中的终端，则执行步骤305；若所述终端不是高速移动中的终端，则执行步骤306。
305、终端选择到第一小区以进行驻留；所述第一小区为高铁专用小区。
306、终端选择第二小区以进行驻留；所述第二小区为除所述专用小区以外的公共小区。
由此可见，若终端为高铁上的终端，高铁在第一小区所属的高铁站台区域停站，若终端对自身进行速度计算，则可能将自身确定为非高速移动中的终端，而无法选择第一小区(即高铁专用小区)进行驻留。因此，第一小区所在基站可向终端发送指示信息以说明针对第一小区时不进行速度计算，终端当前不对自身进行速度计算，直接按照停站前的状态将自身确定为高速移动中的终端，从而可以驻留在第一小区(即高铁专用小区)。
请参见图4，图4为本申请实施例公开的另一种控制方法的流程示意图，该方法包括但不限于如下步骤：
401、终端接收第一小区所在基站发送的指示信息；所述指示信息包含第一权值信息。
本申请实施例可应用于空闲态的终端进行小区重选的应用场景。
作为一种可选的实施方式，上述第一权值信息可为基站发送给终端，也可为终端自身预先存储的；当终端自身预先存储有第一权值信息，则基站只需向终端发送指示终端进行加权速度计算的信息即可。
402、终端获取所述终端在接收到所述指示信息后进行的速度计算的目标结果和至少两个历史速度计算的历史结果；所述历史速度计算为所述终端最近进行的速度计算。
403、终端根据所述第一权值信息对所述目标结果和所述历史结果进行加权计算以获得所述加权速度计算结果，根据所述加权速度计算结果确定所述终端是否为高速移动中的终端；若所述终端是高速移动中的终端，则执行步骤404；若所述终端不是高速移动中的终端，则执行步骤405。
404、终端选择到第一小区以进行驻留；所述第一小区为高铁专用小区。
405、所述终端选择第二小区以进行驻留；所述第二小区为除所述专用小区以外的公共小区。
由此可见，若终端为高铁上的终端，高铁在第一小区所属的高铁站台区域停站，若终端对自身进行速度计算，则可能将自身确定为非高速移动中的终端，而无法选择第一小区(即高铁专用小区)进行驻留。因此，第一小区所在基站可向终端发送指示信息以降低针对第一小区进行的速度计算在最终速度计算结果中所占的权重，终端采用加权的方式进行速度计算之后，依旧可以将自身确定为高速移动中的终端，从而可以驻留在第一小区(即高铁专用小区)。
请参见图5，图5为本申请实施例公开的另一种接入控制方法的流程示意图，该方法包括但不限于如下步骤：
501、终端接收第一小区所在基站发送的指示信息；所述指示信息包含指示所述终端延迟进行速度计算的第一时间阈值。
本申请实施例可应用于空闲态的终端进行小区重选的应用场景。
作为一种可选的实施方式，上述第一时间阈值也可为终端预先存储的，在这种情况下，基站只需向终端发送指示终端延迟进行速度计算的信息即可。
502、终端在接收到所述指示信息之后超过所述第一时间阈值，对所述终端进行速度计算以确定所述终端是否为高速移动中的终端；若所述终端是高速移动中的终端，则执行步骤503；若所述终端不是高速移动中的终端，则执行步骤504。
503、终端选择到第一小区以进行驻留；所述第一小区为高铁专用小区。
504、所述终端选择第二小区以进行驻留；所述第二小区为除所述专用小区以外的公共小区。
由此可见，若终端为高铁上的终端，高铁在第一小区所属的高铁站台区域停车或低速行驶，若终端对自身进行速度计算，则可能将自身确定为非高速移动中的终端，而无法选择第一小区(即高铁专用小区)进行驻留。因此，第一小区所在基站可向终端发送指示信息以使终端延迟进行速度计算，终端在停站时间之后再进行速度计算，依旧可以将自身确定为高速移动中的终端，从而可以驻留在第一小区(即高铁专用小区)。
请参阅图6，图6为本申请实施例公开的一种基站与终端的交互示意图。
601、基站向终端发送指示信息。
可选地，基站获取指示信息。例如，所述基站根据自身的地理位置等信息，生成所述指示信息。或者，所述基站也可以通过其他途径获取所述指示信息，对此不做特别限定。
本申请实施例中，所述基站管理第一小区，该第一小区为高铁专用小区。若第一小区属于高铁站台区域，则高铁在第一小区所属的高铁站台区域停车或低速行驶时，若终端对自身进行速度计算，则可能将自身确定为非高速移动中的终端，而无法选择第一小区(即高铁专用小区)进行驻留。因此，第一小区所在基站可向终端发送指示信息，该指示消息可以包含如下内容：
所述指示信息包含指示所述第一小区是否属于预设区域的标识。或者，所述指示信息包含指示终端是否进行速度计算的标识。或者，所述指示信息包含第一权值信息；所述第一权值信息为所述终端在接收到所述指示信息后进行的速度计算在加权速度计算结果中所占权重。或者，所述指示信息包含指示所述终端采用加权计算进行速度计算的标识。或者，所述指示信息包含指示所述终端延迟进行速度计算的第一时间阈值。或者，所述指示信息包含指示所述终端延迟速度计算的标识。
602、所述终端根据所述指示信息确定所述终端是否为高速移动中的终端。
603、当所述终端不是高速移动中的终端时，所述终端选择第二小区以进行驻留。所述第二小区为除所述高铁专用小区以外的公共小区。
由此可见，第一小区所在基站可向终端发送指示信息以使终端对速度计算进行调整(是否进行速度计算、是否进行加权速度计算、进行速度计算的时机)，从而当终端在高铁上时， 依旧可以将自身确定为高速移动中的终端，从而可以驻留在第一小区(即高铁专用小区)。

作为一种可选的实施方式，上述识别标识可由高铁上提供的二维码信息获得；或者， 在高速移动工具上配置识别设备，用于在预设的覆盖区域内广播该识别标识。

终端在接收到该提示消息之后，向基站发送上述接入请求消息。
152、根据所述接入请求消息确定所述终端为高铁上的终端，允许所述终端接入所述基站的小区；所述基站的小区为高铁专用小区。
作为一种可选的实施方式，基站根据所述接入请求消息从所述终端的归属签约用户服务器HSS获取所述终端的用户注册信息(例如用户的手机号码、身份证号等)；之后根据所述用户注册信息在对应高铁的数据库查询是否存在所述终端对应的用户的条目，即查询高铁的数据库中是否存在用户的高铁购票信息；若存在用户的高铁购票信息，则根据用户的乘车时间，将乘车时间内的终端确定为高铁上的终端。
请参阅图11，图11为本申请实施例公开的另一种基站1100的结构示意图。该基站可执行如图1A至图1D所示的方法中的基站的操作，或者该基站也可以执行图10所示的方法中的基站的操作。
基站1100包括一个或多个远端射频单元(remote radio unit,RRU)1101和一个或多个基带单元(baseband unit，BBU)1102。所述RRU1101可以称为收发单元、收发机、收发电路、或者收发器等等，其可以包括至少一个天线1111和射频单元1112。所述RRU1101部分主要用于射频信号的收发以及射频信号与基带信号的转换，例如用于向用户设备发送上述实施例中所述的指示信息。所述BBU1102部分主要用于进行基带处理，对基站进行控制等。所述RRU1101与BBU1102可以是物理上设置在一起，也可以物理上分离设置的，即分布式基站。

当终端开机后，处理器可以读取存储单元中的软件程序，解释并执行软件程序的，处理软件程序的数据。当需要通过无线发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端时，射频电路通过天线接收到射频信号，将射频信号转换为基带信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。
