具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请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，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
目前，相关标准组织正在研究NTN技术，NTN技术一般采用卫星通信的方式向地面用户提供通信服务。相比于地面的蜂窝通信网络，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO
低轨道卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端设备的发射功率要求不高。
2、GEO
地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
请参考图1，其示出了一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是透明转发(transparent payload)的卫星。如图1所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30、接入网设备40和核心网设备50。
终端设备10和接入网设备40之间可通过空口(如Uu接口)进行通信。在图1所示架构中，接入网设备40可以部署在地面，终端设备10和接入网设备40之间的上下行通信，可以通过卫星20和NTN网关30(通常位于地面)进行中转传输。以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号转发给接入网设备40，后续由接入网设备40将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给接入网设备40，接入网设备40将下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
请参考图2，其示出了另一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是再生转发(regenerative payload)的卫星。如图2所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30和核心网设备50。
在图2所示架构中，接入网设备40的功能集成在卫星20上，也即卫星20具备接入网设备40的功能。终端设备10和卫星20之间可通过空口(如Uu接口)进行通信。卫星20和NTN网关30(通常位于地面)之间可通过SRI(Satellite Radio Interface，卫星无线接口)进行通信。
在图2所示架构中，以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
在上述图1和图2所示的网络架构中，接入网设备40是用于为终端设备10提供无线通信服务的设备。接入网设备40与终端设备10之间可以建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备40的数量可以有多个，两个邻近的接入网设备40之间也可以通过有线或者无线的方式进行通信。终端设备10可以在不同的接入网设备40之间进行切换，也即与不同的接入网设备40建立连接。
以蜂窝通信网络为例，蜂窝通信网络中的接入网设备40可以是基站。基站是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。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5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为基站或接入网设备。
另外，本申请实施例中涉及的终端设备10，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，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 device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。在本申请实施例中，有些地方使用“UE”代表“终端设备”。在本申请实施例中，“网络设备”可以是接入网设备(如基站)或者卫星。
另外，以5G NTN网络为例，NTN网络中可以包括多颗卫星20。一颗卫星20可以覆盖一定范围的地面区域，为该地面区域上的终端设备10提供无线通信服务。另外，卫星20可以围绕地球做轨道运动，通过布设多个卫星20，可以实现对地球表面的不同区域的通信覆盖。
另外，在本申请实施例中，名词“网络”和“系统”通常混用，但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于LTE(Long Term Evolution，长期演进)系统，也可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统或者其他通信系统，本申请对此不作限定。
在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。
Cellbarred机制
UE在初始接入阶段，在获得时频域同步后，第一个动作就是读取MIB(Master Information Block，主信息块)。MIB中包含以下两个与小区选择和重选相关的参数：
1、cellBarred：用于指示当前小区是否针对所有UE被禁止接入。如果cellBarred指示为barred(禁止接入)的话，那么处于RRC(Radio Resource Control，无线资源控制)空闲态和RRC非激活态的UE就无法驻留在该小区。
2、intraFreqReselection：用于指示如果当前小区是当前频率的最佳小区，而又不允许UE驻留的时候，是否允许UE选择或者重选到当前频率上的次佳小区上去。
UAC机制
为了网络侧的负荷控制，NR中引入了UAC(Unified Access Control，统一接入控制)机制。首先定义了接入标识(access identity)和接入类别(access category)。
接入标识表征UE本身的身份特征。在NR中目前已经标准化的接入标识有0～15，其中3～10是未定义的部分。
接入类别表征UE发起呼叫的业务属性，其中0～7是标准化的接入类型，而32～63是运营商定义的接入类别，其他的则是未定义的接入类别。
RAN(Radio Access Network，无线接入网)广播与接入类别和接入标识相关的接入控制信息，UE AS(Access Stratum，接入层)则根据广播的接入控制信息和AS/NAS(Non Access Stratum，非接入层)提供的接入类别和接入标识执行ACB(Access Class Barring，接入等级限制)检查。
UAC参数是针对每个接入类别、针对每个PLMN(Public Land Mobile Network，公共陆地移动网络)配置的。
网络侧最多配置8个UAC-BarringInfoSet，每个UAC-BarringInfoSet包含如下参数：
(a)uac-BarringFactor：表示接入尝试被允许通过的概率。
(b)uac-BarringTime：用于确定某个接入类别发起的接入尝试失败之后到同一个接入类别再次发起下一次接入尝试的最小时间间隔。
(c)uac-BarringForAccessIdentity：用于分别确定每个接入标识是否允许进行接入尝试。
每个接入类别关联一个UAC-BarringInfoSet，总共64个接入类别(接入类别0不需要配置)。可以针对每个PLMN配置，每个PLMN关联一个UAC-BarringPerCatList。如果针对每个PLMN信息不配置，则上述配置是对所有PLMN适用。
针对接入类别1，配置uac-AccessCategory1-SelectionAssistanceInfo，辅助判断是否ACB检查用于针对接入类别1。
基于上述UAC配置参数，UE执行UAC检查的过程如下：
S1：前提是T390和T302这两个定时器都没有运行且接入类别不是0；则按照UAC配置信息判决，执行步骤S2；
S2：如果接入标识在uac-BarringForAccessIdentity中的对应比特设置为0，表示允许接入，如果对应比特设置为1，则需要进一步判决，执行步骤S3；
S3：产生0≤rand<1随机数字，如果随机数字rand小于uac-BarringFactor，则表示允许接入，否则表示禁止接入。如果禁止接入，则产生0≤rand<1随机数字，启动T390且T390＝(0.7+0.6*rand)*uac-BarringTime。
对于NAS触发的事件，NAS决定接入标识、接入类别以及原因值(cause value)。NAS提供接入标识和接入类别给AS，AS负责ACB检查，如果通过，AS通知NAS，NAS提供原因值给AS。基于AS的ACB检查反馈，NAS负责执行停止或允许业务传输。
对于AS触发的事件，包括寻呼(paging)触发，RNAU(RAN-based Notification Area Update，基于无线接入网的通知区域更新)触发(NAS和AS之间交互信息属于UE实现行为)，其中：
Paging：接入类别为0，不受ABC控制。会重写原因值，NAS和AS之间交互，NAS提供原因值信息。
RNAU：接入类别为8，AS决定，接入标识需要NAS给AS提供，如何以及何时交互属于实现。原因值AS决定为rna-Update。
与传统NR采用的蜂窝网络相比，NTN中UE与卫星之间的信号传播时延大幅增加。此外，由于卫星的覆盖范围很大，对于同一个卫星覆盖范围内的不同UE，由于其所处的位置不同，他们与卫星之间的信号传输时延也可能存在较大差异。根据目前标准化过程中针对NTN应用场景的讨论，一个NTN小区内不同UE与基站之间的信号传输时延的最大差值为10.3ms。如此大的信号传输时延差异将会导致使用相同的RACH(Random Access Channel，随机接入信道)资源发送前导码(preamble)的不同UE，他们发送的前导码在不同的时间到达基站。为了保证基站能够接收到小区内不同UE发送的前导码，基站侧的前导码接收窗长度应该扩展为2*(最大单向时延-最小单向时延)，如图3所示。
基站在收到前导码后，需要知道UE在哪个RO(RACH Occasion，随机接入信道时机)发送的前导码，从而确定UE的初始TA(Timing Advance，定时提前)。在NTN中，由于需要引入较长的前导码接收窗，如图4所示，如果时域上相邻的RO之间的时间间隔小于前导码接收窗的窗长，则会出现位于不同时间的RO对应的前导码接收窗在时域上重叠的问题，这样基站在多个前导码接收窗的重叠区域接收到前导码，就无法知道UE在哪个RO发送的该前导码，也就不能确定该UE的TA了。
针对NTN中网络侧可能出现的前导码接收窗模糊的问题，一种思路是网络在配置RACH资源时保证 时域上相邻RO的时间间隔不小于RACH接收窗长，这种方法的弊端是会降低RACH容量。
另外，对于具有TA预补偿能力的终端设备，从其随机接入的流程来看，UE可以自己估算TA并使用自己估算的TA发送前导码，由于该UE在发送前导码之前已经调整了自己的上行定时，因此对于具有TA预补偿能力的UE，网络实际上就不需要使用上述扩展的RACH接收窗进行前导码接收。因此，对于具有TA预补偿能力的终端设备，由于不需要使用扩展的RACH接收窗进行前导码接收，所以也就不存在对相邻RO的时间间隔的限制，从而在一定程度上提高了RACH容量。
本申请通过终端设备根据来自网络设备的第一信息(该第一信息用于确定第一终端类型和第二终端类型中每种终端类型对应的终端设备被允许或被禁止接入网络设备对应的小区)和终端设备所属的终端类型，确定网络设备对应的小区允许或禁止该终端设备接入，从而实现针对不同的终端类型分别进行小区接入控制，能够更灵活地控制各类终端的接入，更好地利用网络资源。
另外，在一些实施例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，终端设备优先判断网络设备对应的小区是否允许第一终端类型对应的终端设备接入，进一步地，如果确定网络设备对应的小区禁止第一终端类型对应的终端设备接入，终端设备进一步判断网络设备对应的小区是否允许第二终端类型对应的终端设备接入，通过两步判断，更大限度地保证终端设备使用TA预补偿能力接入网络，以保证RACH容量，并在网络拥塞的时候也可以不使用TA预补偿能力进行接入，增加了接入成功的机会，从而提高接入成功率。
下面，将通过几个示例性实施例对本申请技术方案进行介绍说明。
请参考图5，其示出了本申请一个实施例提供的小区接入控制方法的流程图。该方法可应用于图1或图2所示的网络架构中。该方法可以包括如下步骤(510～520)：
步骤510，网络设备发送第一信息，该第一信息用于确定第一终端类型和第二终端类型中每种终端类型对应的终端设备被允许或被禁止接入网络设备对应的小区。
相应地，终端设备接收来自网络设备的第一信息。
可选地，终端类型至少包括第一终端类型和第二终端类型，该第一终端类型和第二终端类型是两种不同的终端类型，第一信息用于确定网络设备对应的小区允许或禁止第一终端类型对应的终端设备接入，还用于确定网络设备对应的小区允许或禁止第二终端类型对应的终端设备接入。
可选地，终端类型基于终端设备所具备的能力确定，也即可以依据不同终端设备所具备的不同能力，对终端设备进行类型划分。可选地，终端类型基于以下至少一项能力确定：TA预补偿能力、定位能力。可选地，TA预补偿能力是指终端设备使用定位能力结合卫星的星历信息和/或系统信息广播的时间信息进行TA预补偿的能力。例如，在终端设备具有TA预补偿能力的情况下，其能够估算出自身到卫星之间的服务链路(service link)对应的TA，同时结合网络广播的公共TA(common TA)等信息得到第一TA，并使用该第一TA进行TA补偿发送msg1，msg1是随机接入过程中发送前导码的消息。可选地，定位能力是指终端设备获取自身位置信息的能力，如GNSS(Global Navigation Satellite System，全球导航卫星系统)定位能力。
在示例性实施例中，在终端类型至少包括第一终端类型和第二终端类型的情况下，第一终端类型具有TA预补偿能力，且第二终端类型不具有TA预补偿能力。或者，第一终端类型具有定位能力，且第二终端类型不具有定位能力。或者，第一终端类型具有TA预补偿能力和定位能力，且第二终端类型不具有TA预补偿能力和/或定位能力。
可选地，第一信息用于显式或者隐式指示第一终端类型和第二终端类型中每种终端类型对应的终端设备被允许或被禁止接入网络设备对应的小区。在示例性实施例中，第一信息包括以下之一：小区接入禁止指示信息、随机接入资源配置信息、UAC配置信息。有关上述各项信息的介绍说明请参见下文实施例。
在示例性实施例中，网络设备通过系统信息(system information)发送第一信息。例如，网络设备发送系统信息，该系统信息中包括第一信息；相应地，终端设备接收来自网络设备的系统信息，该系统信息中包括第一信息。可选地，网络设备广播系统信息，该系统信息中包括第一信息。
在一个示例中，第一信息完整地在一个MIB中。在一些实施例中，考虑到MIB中已经具有小区接入禁止指示信息(即上文介绍的cellBarred信息)，该MIB中的小区接入禁止指示信息可以重用给某一种终端类型使用(具体重用给哪一种终端类型可以由协议约定或新增配置)，另外在MIB中新增小区接入禁止指示信息应用于其他终端类型。以上文介绍的第一终端类型和第二终端类型为例，MIB中原有的小区接入禁止指示信息可以重用给第一终端类型使用，即基于MIB中原有的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第一终端类型对应的终端设备接入，在MIB中新增一个小区接入禁止指示信息(如MIB中剩余的1bit预留字段用于该新增的小区接入禁止指示信息)给第二终端类型使用，即基于MIB中 新增的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第二终端类型对应的终端设备接入。或者，MIB中原有的小区接入禁止指示信息可以重用给第二终端类型使用，即基于MIB中的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第二终端类型对应的终端设备接入，在MIB中新增一个小区接入禁止指示信息(如MIB中剩余的1bit预留字段用于该新增的小区接入禁止指示信息)给第一终端类型使用，即基于MIB中新增的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第一终端类型对应的终端设备接入。
在另一个示例中，第一信息完整地在一个SIB(System Information Block，系统信息块)中。可选地，该SIB可以是SIB 1，也可以是SIB 2，或者是其他SIB，本申请对此不作限定。可选地，利用SIB中未使用的比特位，指示至少两种终端类型(如包括第一终端类型和第二终端类型)分别对应的小区接入禁止指示信息。
在另一个示例中，第一信息分散在一个MIB和至少一个SIB中，或者，第一信息分散在多个SIB中。其中，SIB可以是SIB 1，也可以是SIB 2，或者是其他SIB，本申请对此不作限定。在一些实施例中，考虑到MIB中已经具有小区接入禁止指示信息(即上文介绍的cellBarred信息)，该MIB中的小区接入禁止指示信息可以重用给某一种终端类型使用(具体重用给哪一种终端类型可以由协议约定或新增配置)，另外在SIB中新增小区接入禁止指示信息应用于其他终端类型。以上文介绍的第一终端类型和第二终端类型为例，MIB中的小区接入禁止指示信息可以重用给第一终端类型使用，即基于MIB中的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第一终端类型对应的终端设备接入，在SIB(如SIB 1、SIB 2或者其他SIB)中新增的小区接入禁止指示信息给第二终端类型使用，即基于SIB中的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第二终端类型对应的终端设备接入。或者，MIB中的小区接入禁止指示信息可以重用给第二终端类型使用，即基于MIB中的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第二终端类型对应的终端设备接入，在SIB(如SIB 1、SIB 2或者其他SIB)中新增的小区接入禁止指示信息给第一终端类型使用，即基于SIB中的小区接入禁止指示信息确定网络设备对应的小区允许或禁止第一终端类型对应的终端设备接入。
步骤520，终端设备根据来自网络设备的第一信息和终端设备所属的终端类型，确定网络设备对应的小区允许或禁止该终端设备接入。
在下文解释中，为了简化描述，将“网络设备对应的小区”称为“小区”。
可选地，终端设备根据确定的小区允许或者禁止终端设备接入的结果，接入或者不接入小区。例如，终端设备确定小区允许其接入，则接入该小区；终端设备确定小区禁止其接入，则不接入该小区。
可选地，第一终端类型接入小区的优先级比第二终端类型高。也即，在终端设备属于第一终端类型的情况下，优先判断小区是否允许第一终端类型对应的终端设备接入。
在一个示例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息指示小区允许第一终端类型对应的终端设备(即属于第一终端类型的终端设备)接入，则终端设备确定小区允许该终端设备接入。可选地，在第一信息指示小区禁止第一终端类型对应的终端设备接入的情况下，若第一信息指示小区允许第二终端类型对应的终端设备(即属于第二终端类型的终端设备)接入，则终端设备确定小区允许该终端设备接入。另外，在第一信息指示小区禁止第一终端类型对应的终端设备接入的情况下，若第一信息指示小区禁止第二终端类型对应的终端设备接入，则终端设备确定小区禁止该终端设备接入。
也就是说，在终端设备属于第一终端类型的情况下，终端设备先基于第一信息确定小区允许或禁止第一终端类型对应的终端设备接入；若小区允许第一终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入。可选地，若小区禁止第一终端类型对应的终端设备接入，则终端设备再基于第一信息确定小区允许或禁止第二终端类型对应的终端设备接入；若小区允许第二终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入。另外，若小区禁止第二终端类型对应的终端设备接入，则终端设备确定小区禁止该终端设备接入。
在另一个示例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息指示小区允许第一终端类型对应的终端设备和/或第二终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入。另外，若第一信息指示小区禁止第一终端类型对应的终端设备和第二终端类型对应的终端设备接入，则终端设备确定该小区禁止终端设备接入。
也就是说，在终端设备属于第一终端类型的情况下，终端设备基于第一信息确定小区允许或禁止第一终端类型对应的终端设备接入，以及确定小区禁止或允许第二终端类型对应的终端设备接入；若小区允许第一终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入。可选地，若小区禁止第一终端类型对应的终端设备接入，且允许第二终端类型对应的终端设备接入，则终端设备确定小区允许该终 端设备接入。另外，若小区禁止第一终端类型对应的终端设备接入，且禁止第二终端类型对应的终端设备接入，则终端设备确定小区禁止该终端设备接入。
上述两个示例是等效方案，仅是步骤执行顺序存在一定差别。
可选地，在终端设备属于第一终端类型的情况下，如果小区允许第一终端类型对应的终端设备接入，终端设备使用配置给第一终端类型的随机接入资源进行随机接入；如果小区禁止第一终端类型对应的终端设备接入，且允许第二终端类型对应的终端设备接入，终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
在另一个示例中，在终端设备属于第二终端类型(例如终端设备不具有TA预补偿能力，或者终端设备不具有定位能力，或者终端设备不具有TA预补偿能力和/或定位能力)的情况下，若第一信息指示小区允许第二终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入。另外，若第一信息指示小区禁止第二终端类型对应的终端设备接入，则终端设备确定小区禁止该终端设备接入。
也就是说，在终端设备属于第二终端类型的情况下，终端设备基于第一信息确定小区禁止或允许第二终端类型对应的终端设备接入；若小区允许第二终端类型对应的终端设备接入，则终端设备确定小区允许该终端设备接入；若小区禁止第二终端类型对应的终端设备接入，则终端设备确定网络设备对应的小区禁止该终端设备接入。
可选地，在终端设备属于第二终端类型的情况下，如果小区允许第二终端类型对应的终端设备接入，终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
需要说明的是，由于随机接入资源(如上文介绍的RO)存在多个，该多个随机接入资源可以占用不同的时频域位置，终端设备在选择随机接入资源进行随机接入时，从该多个随机接入资源中选择一个随机接入资源即可，例如从多个RO中选择一个RO发送前导码即可，不同的终端设备可以选择不同的随机接入资源发起随机接入，如选择不同的RO发送前导码。因此，即便按照上文介绍的示例性方案，对于属于第一终端类型的终端设备，其使用第二终端类型对应的随机接入资源进行随机接入，通常也能够实现第一终端类型和第二终端类型对应的终端设备均可发起随机接入，例如第一终端类型对应的终端设备和第二终端类型对应的终端设备，在不同的RO发送前导码。可选地，在某些情况下，如果没有多个随机接入资源可供选择，那么可以优先让第一终端类型对应的终端设备接入。例如，当出现第一终端类型对应的终端设备和第二终端类型对应的终端设备，需要使用同一个RO发送前导码时，可以优先让第一终端类型对应的终端设备使用这一个RO发送前导码，保证第一终端类型对应的终端设备优先接入。当然，在一些其他实施例中，如果没有多个随机接入资源可供选择，那么可以优先让第二终端类型对应的终端设备接入，本申请对此不作限定。
本申请通过终端设备根据来自网络设备的第一信息(该第一信息用于确定第一终端类型和第二终端类型中每种终端类型对应的终端设备被允许或被禁止接入网络设备对应的小区)和终端设备所属的终端类型，确定网络设备对应的小区允许或禁止该终端设备接入，从而实现针对不同的终端类型分别进行小区接入控制，能够更灵活地控制各类终端的接入，更好地利用网络资源。
另外，在一些实施例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，终端设备优先判断网络设备对应的小区是否允许第一终端类型对应的终端设备接入，进一步地，如果确定网络设备对应的小区禁止第一终端类型对应的终端设备接入，终端设备进一步判断网络设备对应的小区是否允许第二终端类型对应的终端设备接入，通过两步判断，更大限度地保证终端设备使用TA预补偿能力接入网络，以保证RACH容量，并在网络拥塞的时候也可以不使用TA预补偿能力进行接入，增加了接入成功的机会，从而提高接入成功率。
在示例性实施例中，第一信息包括小区接入禁止指示信息，小区接入禁止指示信息用于指示允许接入或禁止接入。可选地，小区接入禁止指示信息可以是小区禁止cellBarred信息，该cellBarred信息用于显式指示允许或禁止驻留在网络设备对应的小区中。例如，cellBarred信息指示Barred表示禁止接入，cellBarred信息指示NotBarred表示允许接入。
可选地，对于第一终端类型和第二终端类型中的每种终端类型，在终端类型对应的小区接入禁止指示信息为第一指示信息的情况下，指示小区允许该终端类型对应的终端设备接入，如指示小区允许该终端类型对应的终端设备驻留；或者，在终端类型对应的小区接入禁止指示信息为第二指示信息的情况下，指示小区禁止该终端类型对应的终端设备接入，如指示小区禁止该终端类型对应的终端设备驻留。其中，第一指示信息和第二指示信息不同，例如第一指示信息为0且第二指示信息为1，或者第一指示信息为1且第二指示信息为0。
以cellBarred信息为例，cellBarred信息可以通过bit(比特)实现。例如，通过1个bit来表示cellBarred 信息，例如1bit为0或1。例如，0指示Barred表示允许接入，1指示NotBarred表示禁止接入；或者，1指示Barred表示允许接入，0指示NotBarred表示禁止接入。
在一个示例中，在第一信息包括小区接入禁止指示信息的情况下，终端设备根据自身所属的终端类型所对应的小区接入禁止指示信息，确定网络设备对应的小区允许或禁止该终端设备接入。例如，如图6所示，若第一信息中包含的终端设备所属的终端类型所对应的小区接入禁止指示信息指示允许接入，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)；或者，若第一信息中包含的终端设备所属的终端类型所对应的小区接入禁止指示信息指示禁止接入，则终端设备确定网络设备对应的小区禁止该终端设备接入(如驻留)。示例性地，假设第一终端类型对应的小区接入禁止指示信息指示允许接入，第二终端类型对应的小区接入禁止指示信息指示禁止接入，那么如果终端设备属于第一终端类型，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)，如果终端设备属于第二终端类型，则终端设备确定网络设备对应的小区禁止该终端设备接入(如驻留)。
在另一个示例中，如图7所示，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息中包含的第一终端类型对应的小区接入禁止指示信息指示允许接入，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)；或者，若第一信息中包含的第一终端类型对应的小区接入禁止指示信息指示禁止接入，且第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示允许接入，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)；或者，若第一信息中包含的第一终端类型对应的小区接入禁止指示信息指示禁止接入，且第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示禁止接入，则终端设备确定网络设备对应的小区禁止该终端设备接入(如驻留)。
在另一个示例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息中包含的第一终端类型对应的小区接入禁止指示信息指示允许接入，或第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示允许接入，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)；或者，若第一信息中包含的第一终端类型对应的小区接入禁止指示信息指示禁止接入，且第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示禁止接入，则终端设备确定网络设备对应的小区禁止该终端设备接入(如驻留)。
可选地，在终端设备属于第一终端类型的情况下，如果网络设备对应的小区允许第一终端类型接入，则终端设备使用配置给第一终端类型的随机接入资源进行随机接入；或者，如果网络设备对应的小区禁止第一终端类型接入，且允许第二终端类型接入，则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
在另一个示例中，在终端设备属于第二终端类型的情况下(例如终端设备不具有TA预补偿能力，或者终端设备不具有定位能力，或者终端设备不具有TA预补偿能力和/或定位能力)，若第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示允许接入，则终端设备确定网络设备对应的小区允许该终端设备接入(如驻留)；或者，若第一信息中包含的第二终端类型对应的小区接入禁止指示信息指示禁止接入，则终端设备确定网络设备对应的小区禁止该终端设备接入(如驻留)。
可选地，在终端设备属于第二终端类型的情况下，如果网络设备对应的小区允许第二终端类型接入，则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
在示例性实施例中，在确定网络设备对应的小区禁止终端设备接入的情况下，终端设备根据自身所属的终端类型所对应的同频重选指示信息，确定是否允许选择或重选网络设备对应的小区的另一同频小区进行接入。其中，同频小区是指具有相同频率的小区。在一个示例中，同频重选指示信息可以是intraFreqReselection，用于指示如果当前小区是当前频率的最佳小区，而又不允许该终端设备驻留的时候，是否允许该终端设备选择或者重选到当前频率上的次佳小区上去。
可选地，第一信息中还包括至少两种终端类型分别对应的同频重选指示信息。例如，在包括第一终端类型和第二终端类型的情况下，第一信息中除了包括第一终端类型对应的小区接入禁止指示信息和第二终端类型对应的小区接入禁止指示信息之外，还包括第一终端类型对应的同频重选指示信息和第二终端类型对应的同频重选指示信息。
本申请通过给不同的终端类型分别配置相应的小区接入禁止指示信息，通过小区接入禁止指示信息来显式地指示允许接入或禁止接入，实现了对不同的终端类型分别进行小区接入控制。
另外，在一些实施例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，终端设备优先基于第一终端类型对应的小区接入禁止指示信息来确定网络设备对应的小区是否允许该终端设备接入，进一步地，如果确定网络设备对应的小区禁止第一终端类型接入，终端设备进一步基于第二终端类型对应的小区接入禁止 指示信息来确定网络设备对应的小区是否允许该终端设备接入，通过两步判断，更大限度地保证终端设备使用TA预补偿能力接入网络，以保证RACH容量，并在网络拥塞的时候也可以不使用TA预补偿能力进行接入，增加了接入成功的机会，从而提高接入成功率。
在示例性实施例中，第一信息包括随机接入资源配置信息，随机接入资源配置信息用于指示允许接入或禁止接入。可选地，随机接入资源配置信息用于隐式指示允许接入或禁止接入。随机接入资源配置信息是用于配置随机接入资源(如RO)的信息，在一些实施例中，可以利用该随机接入资源配置信息隐式指示允许接入或禁止接入。
可选地，对于第一终端类型和第二终端类型中的每种终端类型，在第一信息中包含该终端类型对应的随机接入资源配置信息的情况下，指示小区允许该终端类型对应的终端设备接入；或者，在第一信息中不包含该终端类型对应的随机接入资源配置信息的情况下，指示小区禁止该终端类型对应的终端设备接入。
可选地，随机接入资源配置信息与第一终端类型存在关联，表示小区允许第一终端类型对应的终端设备接入；和/或，随机接入资源配置信息与第二终端类型存在关联，表示小区允许第一终端类型对应的终端设备接入。
换句话说，第一信息中包含第一终端类型对应的随机接入资源配置信息，和/或，第一信息中包含第二终端类型对应的随机接入资源配置信息，表示小区允许第一终端类型对应的终端设备接入。第一信息中不包含第一终端类型对应的随机接入资源配置信息，并且，第一信息中不包含第二终端类型对应的随机接入资源配置信息，表示小区禁止第一终端类型对应的终端设备接入，同时也表示小区禁止第二终端类型对应的终端设备接入。第一信息中包含第一终端类型对应的随机接入资源配置信息，但是，第一信息中不包含第二终端类型对应的随机接入资源配置信息，表示小区禁止第二终端类型对应的终端设备接入。
在一个示例中，在第一信息包括随机接入资源配置信息的情况下，终端设备根据第一信息中是否包含自身所属的终端类型所对应的随机接入资源配置信息，确定网络设备对应的小区允许或禁止该终端设备接入。例如，如图8所示，若第一信息中包含终端设备所属的终端类型所对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若第一信息中不包含终端设备所属的终端类型所对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区禁止该终端设备接入。示例性地，假设第一信息中包括第一终端类型对应的随机接入资源配置信息，第一信息中不包括第二终端类型对应的随机接入资源配置信息，那么如果终端设备属于第一终端类型，则终端设备确定网络设备对应的小区允许该终端设备接入，如果终端设备属于第二终端类型，则终端设备确定网络设备对应的小区禁止该终端设备接入。
在另一个示例中，如图9所示，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息中包含第一终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若第一信息中不包含第一终端类型对应的随机接入资源配置信息，且第一信息中包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若第一信息中不包含的第一终端类型对应的随机接入资源配置信息，且第一信息中不包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区禁止该终端设备接入。
在另一个示例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若第一信息中包含第一终端类型对应的随机接入资源配置信息，或第一信息中包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若第一信息中不包含第一终端类型对应的随机接入资源配置信息，且第一信息中不包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区禁止该终端设备接入。
可选地，在终端设备属于第一终端类型的情况下，如果网络设备对应的小区允许第一终端类型接入，则终端设备使用配置给第一终端类型的随机接入资源进行随机接入；或者，如果网络设备对应的小区禁止第一终端类型接入，且允许第二终端类型接入，则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
在另一个示例中，在终端设备属于第二终端类型的情况下(例如终端设备不具有TA预补偿能力，或者终端设备不具有定位能力，或者终端设备不具有TA预补偿能力和/或定位能力)，若第一信息中包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若第一信息中不包含第二终端类型对应的随机接入资源配置信息，则终端设备确定网络设备对应的小区禁止该终端设备接入。
可选地，在终端设备属于第二终端类型的情况下，如果网络设备对应的小区允许第二终端类型接入， 则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
本申请通过给不同的终端类型分别配置/不配置相应的随机接入资源配置信息，通过随机接入资源配置信息来隐式地指示允许接入或禁止接入，实现了对不同的终端类型分别进行小区接入控制。
另外，在一些实施例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，终端设备优先基于第一信息中是否包含第一终端类型对应的随机接入资源配置信息来确定网络设备对应的小区是否允许该终端设备接入，进一步地，如果确定网络设备对应的小区禁止第一终端类型接入，终端设备进一步基于第一信息中是否包含第二终端类型对应的随机接入资源配置信息来确定网络设备对应的小区是否允许该终端设备接入，通过两步判断，更大限度地保证终端设备使用TA预补偿能力接入网络，以保证RACH容量，并在网络拥塞的时候也可以不使用TA预补偿能力进行接入，增加了接入成功的机会，从而提高接入成功率。

可选地，对于第一终端类型和第二终端类型中的每种终端类型，在基于该终端类型对应的UAC配置信息执行UAC检查通过的情况下，确定小区允许该终端类型接入；或者，在基于该终端类型对应的UAC配置信息执行UAC检查未通过的情况下，确定小区禁止该终端类型接入。
可选地，在基于第一终端类型对应的UAC配置信息执行UAC检查通过的情况下，确定小区允许第一终端类型对应的终端设备接入；和/或，在基于第二终端类型对应的UAC配置信息执行UAC检查通过的情况下，确定小区允许第一终端类型对应的终端设备接入。在基于第一终端类型对应的UAC配置信息执行UAC检查未通过，并且，在基于第二终端类型对应的UAC配置信息执行UAC检查未通过的情况下，确定小区禁止第一终端类型对应的终端设备接入。另外，在基于第二终端类型对应的UAC配置信息执行UAC检查通过的情况下，确定小区允许第二终端类型对应的终端设备接入；或者，在基于第二终端类型对应的UAC配置信息执行UAC检查未通过的情况下，确定小区禁止第二终端类型对应的终端设备接入。
可选地，第一终端类型对应的UAC配置信息和第二终端类型对应的UAC配置信息可以相同，也可以不同。在终端设备属于第一终端类型的情况下，终端设备根据第一终端类型对应的UAC配置信息执行UAC检查。在终端设备属于第二终端类型的情况下，终端设备根据第二终端类型对应的UAC配置信息执行UAC检查。另外，上述UAC检查的过程可以如下：
S1：前提是T390和T302这两个定时器都没有运行且接入类别不是0；则按照UAC配置信息判决，执行步骤S2；
S2：如果接入标识在uac-BarringForAccessIdentity中的对应比特设置为0，表示允许接入，如果对应比特设置为1，则需要进一步判决，执行步骤S3；
S3：产生0≤rand<1随机数字，如果随机数字rand小于uac-BarringFactor，则表示允许接入，否则表示禁止接入。如果禁止接入，则产生0≤rand<1随机数字，启动T390且T390＝(0.7+0.6*rand)*uac-BarringTime。
在一个示例中，在第一信息包括UAC配置信息的情况下，终端设备根据自身所属的终端类型所对应的UAC配置信息执行UAC检查，并基于UAC检查结果确定网络设备对应的小区允许或禁止该终端设备接入。例如，如图10所示，终端设备基于第一信息中包含的自身所属的终端类型所对应的UAC配置信息，执行UAC检查；若UAC检查通过则终端设备确定网络设备对应的小区允许该终端设备接入，或者，若UAC检查未通过则终端设备确定网络设备对应的小区禁止该终端设备接入。示例性地，假设第一信息中包括第一终端类型对应的UAC配置信息和第二终端类型对应的UAC配置信息，那么如果终端设备属于第一终端类型，则终端设备基于第一终端类型对应的UAC配置信息执行UAC检查，并在UAC检查通过的情况下确定网络设备对应的小区允许该终端设备接入，在UAC检查未通过的情况下确定网络设备对应的小区禁止该终端设备接入；如果终端设备属于第二终端类型，则终端设备基于第二终端类型对应的UAC配置信息执行UAC检查，并在UAC检查通过的情况下确定网络设备对应的小区允许该终端设备接入，在UAC检查未通过的情况下确定网络设备对应的小区禁止该终端设备接入。
在另一个示例中，如图11所示，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查通过，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查未通 过，且基于第一信息中包含的第二终端类型对应的UAC配置信息执行UAC检查通过，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查未通过，且基于第一信息中包含的第二终端类型对应的UAC配置信息执行UAC检查未通过，则终端设备确定网络设备对应的小区禁止该终端设备接入。
在另一个示例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，若基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查通过，或基于第一信息中包含的第二终端类型对应的UAC配置信息执行UAC检查通过，则终端设备确定网络设备对应的小区允许该终端设备接入；或者，若基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查未通过，且基于第一信息中包含的第一终端类型对应的UAC配置信息执行UAC检查未通过，则终端设备确定网络设备对应的小区禁止该终端设备接入。
可选地，在终端设备属于第一终端类型的情况下，如果网络设备对应的小区允许第一终端类型接入，则终端设备使用配置给第一终端类型的随机接入资源进行随机接入；或者，如果网络设备对应的小区禁止第一终端类型接入，且允许第二终端类型接入，则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
在另一个示例中，在终端设备属于第二终端类型的情况下(例如终端设备不具有TA预补偿能力，或者终端设备不具有定位能力，或者终端设备不具有TA预补偿能力和/或定位能力)，终端设备基于第一信息中包含的第二终端类型对应的UAC配置信息执行UAC检查，若UAC检查通过则确定网络设备对应的小区允许该终端设备接入，若UAC检查未通过则确定网络设备对应的小区禁止该终端设备接入。
可选地，在终端设备属于第二终端类型的情况下，如果网络设备对应的小区允许第二终端类型接入，则终端设备使用配置给第二终端类型的随机接入资源进行随机接入。
本申请通过给不同的终端类型分别配置相应的UAC配置信息，通过基于UAC配置信息执行UAC检查来确定允许接入或禁止接入，实现了对不同的终端类型分别进行小区接入控制。
另外，在一些实施例中，在终端设备属于第一终端类型的情况下(例如终端设备具有TA预补偿能力，或者终端设备具有定位能力，或者终端设备具有TA预补偿能力和定位能力)，终端设备优先基于第一终端类型对应的UAC配置信息来确定网络设备对应的小区是否允许该终端设备接入，进一步地，如果确定网络设备对应的小区禁止第一终端类型接入，终端设备进一步基于第二终端类型对应的UAC配置信息来确定网络设备对应的小区是否允许该终端设备接入，通过两步判断，更大限度地保证终端设备使用TA预补偿能力接入网络，以保证RACH容量，并在网络拥塞的时候也可以不使用TA预补偿能力进行接入，增加了接入成功的机会，从而提高接入成功率。
在一些实施例中，在第一信息包括小区接入禁止指示信息(如cellBarred信息)或UAC配置信息的情况下，网络设备还可以为终端设备配置随机接入资源配置信息。可选地，该随机接入资源配置信息可用于配置第一终端类型对应的随机接入资源和/或第二终端类型对应的随机接入资源，以使得终端设备使用某一终端类型对应的随机接入资源发起随机接入。
