具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信(the 5th Generation mobile communication，5G)系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例可以用于不同的制式的无线网络。无线接入网络在不同的系统中可包括不同的通信节点。图1为本申请实施例提供的一种无线网络系统的结构示意图。如图1所示，该无线网络系统100包括基站101、用户设备110、用户设备120和用户设备130。基站101分别与用户设备110、用户设备120和用户设备130之间进行无线通信。
本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站(NodeB)、演进型基 站(evolved NodeB，eNodeB)、5G通信系统中的基站、未来通信系统中的基站、无线保真(Wireless Fidelity，WiFi)系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(Transmission Reference Point，TRP)等，本申请实施例并不限定。
本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、用户设备(User Equipment，UE)单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
在NTN中，由于基站处于高空且通常具有高移动性，通信往往伴随着大时延与高多普勒。当时延与多普勒的大小超过基站容忍范围时，会导致通信质量下降甚至于用户接入失败。
为了应对NTN通信中的大时延与高多普勒，可以为用户提供基站和用户的位置与速度信息，使用户能够计算出相应的时延与多普勒，并进行预补偿。如此，则不需要通过增强物理随机接入信道(Physical Random Access Channel，PRACH)来容忍接入过程中的大时延与大频偏，沿用新空口(New Radio，NR)中的PRACH格式即可完成用户接入。
然而，在不同场景下，用户获得的信息的误差不同，最终计算出的时延与多普勒也会存在不同的误差范围。如果时延与多普勒的误差范围大于对应基站的容忍范围，则即使经过预补偿，接入仍然会失败。
与此同时，用户进行时频预补偿的能力也有一定差异性，且不同用户所支持的网络类型，业务类型等也有所不同；因此，在空间立体网络中，基站需要通过在不同场景下和时间段内对不满足特定条件的用户进行接入限制，以提高网络性能。而传统地面通信网络的机制无法满足该类网络下不同类型基站的多样需求。
在一个实施例中，本申请提供一种接入控制方法，图2为本申请实施例提供的一种接入控制方法的流程示意图。该方法可以适用于确定设备是否允许接入的情况。该方法可以由本申请提供的接入控制装置执行，该接入控制装置可以由软件和/或硬件实现，所述方法应用于第一通信节点中。

在一个示例性的实施方式中，所述方法还包括：
发送第一通信节点信息给第二通信节点，其中，所述第一通信节点信息用于第二通信节点判断是否允许第一通信节点接入网络。
用户可以基于接入配置信息，确定是否接入网络。相应的，基站也可以根据用户设备信息，确定是否允许用户接入。
用户首次接入网络的情况下，由用户进行发起是否接入网络的判定。在用户切换接入网络的情况下，由基站进行发起是否允许用户接入网络。
在一个示例性的实施方式中，所述方法还包括：在尝试接入网络的失败次数达到预设次数的情况下，停止接入网络。
预设次数可以由第二通信节点配置。当第二通信节点根据时频偏门限等不可变参数限制接入时，可以配置较低的预设次数以节约资源；当第二通信节点根据负载等可变参数限制接入时，可以配置较高的预设次数以提供更多接入机会。
在一个示例性的实施方式中，所述接入配置消息包括如下一个或多个：
接入条件；接入指示；第二通信节点信息。
在一个示例性的实施方式中，所述第二通信节点信息可以是基站状态信息，包括基站的位置、速度和相应的误差范围等。

在一个示例性的实施方式中，所述基于所述接入配置信息，确定是否接入 网络，包括：基于第二通信节点发送的接入指示，确定是否接入网络。
在一个示例性的实施方式中，所述接入指示包括如下一个或多个：
允许接入；不允许接入；暂缓接入。
在本实施例中，如果接入指示是允许接入，则确定用户接入网络。
如果接入指示是不允许接入，则确定用户禁止接入网络。
如果接入指示是暂缓接入，则确定用户在一段时间内禁止接入网络。等待时间可由第二通信节点配置。
在一个示例性的实施方式中，所述基于所述接入配置信息，确定是否接入网络，包括：在未满足所述接入条件的情况下，停止接入网络。
在一个示例性的实施方式中，所述在未满足所述接入条件的情况下，停止接入网络，包括：
确定本节点的节点类型；在所述本节点的节点类型非第二通信节点的服务类型的情况下，停止接入网络。
在本实施例中，节点类型可以按照业务分类，例如：窄带(Narrow Band，NB)终端，LTE终端。
在本实施例中，节点类型可以按照节点所处分级确定，例如：不同的功率等级，支持的天线配置(如是否支持圆极化等)；在本实施例中，节点类型可以按照节点能力确定，例如：是否支持预补偿能力等。
节点类型也可以按照站点类型进行分类，例如：普通终端，relay节点，IAB节点等。
如果本节点是普通终端，基站仅允许IAB终端接入网络，此时，普通终端应该禁止接入网络。
在一个示例性的实施方式中，所述在未满足所述接入条件的情况下，停止接入网络，包括：
在上行传输的信号功率大于上行信号功率门限的情况下，停止接入网络。
在一个示例性的实施方式中，所述在未满足所述接入条件的情况下，停止接入网络，包括：

将所述接入条件通过广播信令广播至第一通信节点；将所述接入条件预存在所述第一通信节点的客户识别模块(Subscriber Identity Module，SIM)卡或全球客户识别模块(Universal Subscriber Identity Module，USIM)卡中。
在一个示例性的实施方式中，向所述第一通信节点发送第二通信节点信息，包括如下一种或多种：
将所述第二通信节点信息通过广播信令广播至第一通信节点；通过SIB类型隐式传递第二通信节点信息；通过不同频段、PLMN安排和小区ID隐式传递第二通信节点信息。
在一个示例性的实施方式中，所述接入条件包括如下一个或多个：

本申请提供一种接入限制的发起与信息传递方法。
接入限制既可以在网络侧发起，也可以在用户侧发起。本申请中的网络侧可以理解为上述基站或者第二通信节点，本实施例中的用户侧可以理解为用户设备，用户终端，或者第一通信节点。
在一个应用性实例中，基站根据一定条件对用户发起接入限制。
第一种：基站获得用户的种类与状态信息，判断用户是否满足接入条件。如果不满足接入条件，则基站向用户发送不允许接入的指示来限制其接入。用户不需要知道接入限制相关信息，但其种类与状态信息需要首先被基站知道，在切换时这个条件可以得到满足。对于这种情况，用户的信息可以通过核心网从源基站传递给目标基站，基站仅需要向目标用户传递接入指示来表示是否允许接入网络即可。
第二种：基站不知道用户的种类与状态信息，但可以将接入条件传递给用户，让用户判断自己是否满足接入条件。如果不满足，则用户不会向基站发起接入。
对于第二种情况，可以考虑以下信息传递方法：
方式一：将基站接入条件通过信令广播给用户，可以通过以下子选项中的方式：
(1)在MIB或SIB等广播信令中定义一块比特域，用来传递基站的接入条件，例如基站所能容忍的时偏与频偏范围。比特域长度由接入条件决定，例如若接入条件为时频偏小于一定范围，则所需比特数由最大范围和量化精度所决定。
(2)在MIB或SIB等广播信令中定义一块比特域，用来传递基站的类型，而每种类型基站对应的接入条件事先存在用户本地。比特域长度为X＝ceil(log2(NumOfBSType))，其中NumOfBSType为基站的种类数。
(3)通过SIB种类暗示性地传递基站类型。每种基站分别对应一种SIB，用户根据译码出来的SIB种类来判断基站类型。每种类型基站对应的接入条件事先存在用户本地。
(4)通过采用不同的频段、PLMN安排以及小区ID等信息来暗示性地传递基站类型。用户根据对应的信息来判断基站的种类。每种类型基站对应的接入条件事先存在用户本地。
方式二：将基站接入条件预存在用户的SIM卡或USIM卡中。用户在获得基站信息后，可以通过查找预存信息获得该基站的接入条件，不需要为传递接入条件耗费额外的信令。
若接入限制仅在部分场景或时间段下发起，则还需要在MIB或SIB中使用额外1比特使能信息来标识接入限制条件的有效性。
在一个应用性实例中，用户根据一定条件主动发起接入限制。
第一种：用户尝试接入基站，失败一定次数后停止接入该基站。这种情况 下，用户与基站间不需要额外的信令交互。
第二种：用户事先在SIM或USIM中存储了可以接入的基站类型，如果基站类型不符合要求，则用户不会发起接入。即使基站是用户可以接入的类型，用户在发起接入前也需要判断基站的接入条件是否得到满足。
接入限制可以由多种因素触发。在触发场景不同时，接入限制的发起流程与所需传递的消息内容会有所不同。本申请对于触发场景不同的接入发起流程与所需传递的消息内容依次进行说明。
在一个应用性的实施方式中，基站设置时偏(Timing Offset，TO)和频偏(Frequency Offset，TO)的容忍范围，限制TO或FO大于容忍范围的用户接入。
在NTN中，由于空中通信节点通常距离地面用户很远且具有较高的移动性，通信链路往往会受到大时延与高多普勒的影响。为了处理大时延与高多普勒，通常会为用户提供基站和用户的位置与速度信息，使用户能够计算出相应的TO与FO，并进行预补偿。然而，由于定位信息会存在一定误差，计算得到的TO与FO也会相应出现误差。如果最终残余的TO或FO过大，超过基站能够容忍的范围，则这些用户的接入应该受到限制。
在这种情况下，接入限制可以由基站发起。
在初始接入时，基站首先向用户传递接入配置消息，包括自身状态信息(位置、速度和相应的误差范围)与所能容忍的TO与FO门限。用户根据基站和自身的状态信息估计自己所能达到的TO与FO计算精度，获得预补偿后残余的TO与FO范围。如果TO的最大值大于TO门限或FO的最大值大于FO门限，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为TO与FO过大的原因受到限制。
在切换时，目标基站通过核心网从源基站中获得用户信息，估计其预补偿后残余的TO与FO范围。如果TO的最大值大于TO门限或FO的最大值大于FO门限，则认为接入受到限制，向用户发送不允许接入的指示；否则，认为接入不会因为TO与FO过大的原因受到限制。
在一个应用性的实施方式中，基站仅允许特定类型的用户接入。
不同用户硬件配置不同，具有不同的通信能力和功能，因而会划分多个用户类别(UE category)。基站可以仅服务目标类型用户，限制其他类型用户的 接入。
例如：基站仅允许功率等级(power class)足够高的用户接入，限制power class低的用户接入，以提高网络性能。此时，UE category根据用户的power class进行划分。具有不同power class的用户会被分为不同的UE category，网络可以对归属于特定UE category的用户接入进行限制。
例如：基站仅允许集成接入回程(Integrated Access and Backhaul，IAB)终端接入，主要服务于无线回程工作，因而限制普通地面用户的接入。此时，UE category根据用户的终端类型进行划分，包括普通手持终端、IAB终端等。终端类型不同的用户会被分为不同的UE category，网络可以对归属于特定UE category的用户接入进行限制。
例如：基站仅服务窄带物联网(Narrow Band Internet of Things，NB-IoT)业务类型的用户，限制LTE、NR业务类型的用户接入，以提高网络性能。此时，UE category根据用户的业务类型进行划分。具有不同业务类型的用户会被分为不同的UE category，网络可以对归属于特定UE category的用户接入进行限制。
在这些情况下，接入限制可以由基站发起。
在初始接入时，基站首先向用户传递一个列表，其中包含基站所支持的UE category。如果用户的UE category不在该列表中，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为UE category的原因受到限制。
在切换时，目标基站通过核心网从源基站中获得用户信息，得知用户的UE category。如果用户的UE category不是基站可服务的种类且基站可服务种类在短时间内不会变化，则认为接入受到限制，向用户发送不允许接入的指示；如果用户的UE category暂时不能被基站服务，但预计一段时间后可以被基站服务，则认为接入暂时受到限制，向用户发送暂缓接入的指示并配置等待时间；否则，认为接入不会因为UE category的原因受到限制。
在一个应用性的实施方式中，基站设置上行信号功率门限，限制上行信号功率大于门限的用户接入。
在多用户接入时，信号功率强的用户会对信号功率弱的用户造成严重干扰，从而降低信号功率弱的用户的接入成功率。因此，基站需要限制上行信号功率过高的用户的接入，以降低对其他用户的干扰。
在这种情况下，接入限制可以由基站发起。
在初始接入时，基站可以通过以下方式告知用户接入是否受到限制：
方式一：若用户发送功率已知，基站接收的上行信号功率由基站与用户的距离决定。因此，基站首先向用户传递接入配置消息，包括自身位置信息与限制接入的距离门限。用户根据基站和自身的位置信息估计与基站的距离。如果估计的距离小于距离门限，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为上行信号功率过高的原因受到限制。
方式二：基站直接测量上行信号的接收功率。如果接收功率大于基站设置的功率门限且功率门限在短时间内不会变化，则认为接入受到限制，向用户发送不允许接入的指示；如果接收功率大于基站设置的功率门限，但预计一段时间后功率门限会提升，则认为接入暂时受到限制，向用户发送暂缓接入的指示并配置等待时间；否则，认为接入不会因为上行信号功率过高的原因受到限制。
方式三：基站首先向用户传递接入配置消息，包括自身位置信息与限制接入的接收功率门限。用户根据基站和自身的位置信息估计与基站的距离，从而计算出路径损耗。如果用户的发送功率减去路径损耗后，仍然大于基站的接收功率门限，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为上行信号功率过高的原因受到限制。
在切换时，基站可以通过以下方式告知用户接入是否受到限制：
方式一：目标基站通过核心网从源基站中获得用户位置信息，计算用户与目标基站的距离。如果计算的距离小于距离门限，则认为接入受到限制，向用户发送不允许接入的指示；否则，认为接入不会因为上行信号功率过高的原因受到限制。
方式二：目标基站直接测量上行信号的接收功率。如果接收功率大于基站设置的功率门限且功率门限在短时间内不会变化，则认为接入受到限制，向用户发送不允许接入的指示；如果接收功率大于基站设置的功率门限，但预计一段时间后功率门限会提升，则认为接入暂时受到限制，向用户发送暂缓接入的指示并配置等待时间；否则，认为接入不会因为上行信号功率过高的原因受到限制。
方式三：目标基站通过核心网从源基站中获得用户位置信息以及其发送功率。计算用户与目标基站的距离，从而得到路径损耗。如果用户的发送功率减去路径损耗后，仍然大于基站的接收功率门限，则认为接入受到限制，向用户发送不允许接入的指示；否则，认为接入不会因为上行信号功率过高的原因受到限制。
在一个应用性的实施方式中，基站限制特定运营商的用户的接入。
不同运营商的基站可以是分开的，因此一个运营商的基站可以限制另一个运营商的用户的接入。通常，运营商通过PLMN标识进行区分。
在这种情况下，接入限制可以由基站或用户发起。
方式一：由基站发起。在初始接入及切换时，基站首先向用户传递自身信息，包括基站所支持的PLMN列表。如果用户可以接入的PLMN不在支持的PLMN列表中，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为PLMN不支持的原因受到限制。
方式二：由用户发起。在初始接入及切换时，用户通过预存信息判断基站所支持的PLMN。如果用户可以接入的PLMN不在支持的PLMN列表中，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为PLMN不支持的原因受到限制。
在一个应用性的实施方式中，基站限制特定地域的用户的接入。
卫星基站通常具有非常广的覆盖范围，可以跨国覆盖。然而，由于政策等原因，该基站可能只服务特定区域的用户，而限制其他地域用户的接入。
在这种情况下，接入限制可以由基站发起。
在初始接入时，基站可以通过以下方式告知用户接入是否受到限制：
方式一：基站首先向用户传递接入配置消息，包括自身服务的地域范围。该地域范围可以通过一系列坐标点来确定。用户通过定位获取自身位置信息。如果用户的位置在服务的地域范围以外，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为不在服务地域的原因受到限制。
方式二：用户无法定位自身位置或无视地域限制直接接入网络，则基站允许用户先进行进入。在完成接入后，基站通过卫星定位测量用户的位置或者要求用户上报位置信息。如果用户位置不在基站服务的地域范围内，则认为接入受到限制，基站断开连接并向用户发送不允许接入的指示；否则，认为接入不会因为不在服务地域的原因受到限制。
在切换时，目标基站通过核心网从源基站中获得用户位置信息。如果用户位置不在基站服务的地域范围内，则认为接入受到限制，向用户发送不允许接入的指示；否则，认为接入不会因为不在服务地域的原因受到限制。
在一个应用性的实施方式中，基站限制特定网络切片业务类型的用户的接入。
NR的核心网支持多种网络切片，但基站支持的切片业务类型可能不同。如果用户从运营商处订购的网络切片类型与基站支持的切片类型不同，且不接受切片类型的变化，则其接入应该受到限制。
在这种情况下，接入限制可以由基站发起。
在初始接入时，基站首先向用户传递一个列表，其中包含基站所支持的网络切片业务类型。如果用户的网络切片类型不在该列表中，且用户不容许切片类型的变化，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为网络切片类型的原因受到限制。
在切换时，目标基站通过核心网从源基站中获得用户的切片类型以及用户是否容许切片类型改变。如果用户的切片类型不是基站支持的种类，且用户不容许切片类型改变，则认为接入受到限制，基站向用户发送不允许接入的指示；否则，认为接入不会因为网络切片类型的原因受到限制。
在一个应用性的实施方式中，用户仅接入目标类型的基站。
在某些专用网络中，为了提高效率，用户仅接入预先设置好的基站类型。例如对于郊区室外布置的物联网网络，可以指定其用户只接入专门为该网络设计的空对地(Air To Ground，ATG)基站，以避免低效地接入其他通用基站。
在这种情况下，接入限制可以由用户发起。
在初始接入及切换时，用户接收到基站信息后，根据预存在SIM或USIM卡中的基站列表判断该基站是否为自身可接入的类型。如果该基站不在预存的允许接入基站列表中，则认为接入受到限制，用户停止接入网络；否则，认为接入不会因为基站类型的原因受到限制。
在一个应用性的实施方式中，基站根据负载随机限制某些用户的接入。
当基站过载时，接收的接入请求超出容量。为了避免拥塞造成的性能下降，基站可以限制某些用户的接入，即使其他接入限制条件都得到满足。
在这种情况下，接入限制可以由基站发起。
在初始接入及切换时，基站将用户分为多个具有不同优先级的接入类别，并通过以下方式告知用户接入是否受到限制：
方式一：基站直接向用户传递接入指示。基站根据优先级为每个接入类别设置一个负载门限，通常优先级越高的用户设置越高的门限。如果基站的负载大于某个接入类别的负载门限，则将该接入类别的接入指示设置为不允许接入 或暂缓接入。接入时，基站向用户发送一个列表，其中包含每个接入类别的接入指示，并为暂缓接入指示配置相应的等待时间。如果用户所属的接入类别在列表中的指示是不允许接入，则认为接入受到限制，用户停止接入网络；如果用户所属的接入类别在列表中的指示是暂缓接入，则认为接入暂时受到限制，用户在等待时间内停止接入网络；否则，认为接入不会因为接入类别的原因受到限制。
方式二：基站直接向用户传递随机数门限，进行软限制。基站根据自身负载和优先级为每个接入类别设置一个随机数门限，通常负载越低、优先级越高的接入类别设置越高的门限。接入时，基站向用户发送一个列表，其中包含每个接入类别的随机数门限。用户在本地生成随机数，如果随机数大于用户所属接入类别在列表中对应的门限，则认为当前接入受到限制，用户在随机的一段时间内停止接入网络；否则，认为接入不会因为接入类别的原因受到限制。
基站可以将无线资源(频率、时间、波束等)进行划分，以服务不同用户。因此，可以考虑更进一步实行基于无线资源的接入限制，即一个基站对不同的资源块设置不同的接入限制条件，使得网络配置更加灵活高效。
在一个应用性的实施方式中，基站限制用户接入过载的资源块。
每一个资源块(例如一个频段)可以视为一个信道。当该信道过载时，新的用户接入请求应该被限制，以降低负载。
在这种情况下，接入限制可以由基站发起。
方式一：当用户尝试通过某个资源块对应的信道接入时，基站估计该信道的负载，例如已接入用户数等。如果负载大于基站设置的门限值，则认为接入受到限制，基站向尝试通过该信道接入网络的用户发送暂缓的指示，并配置等待时间；否则，认为接入不会因为资源块过载的原因受到限制。
方式二：基站向用户传递各资源块对应信道的负载情况，例如基站通过该信道可提供的服务质量(Quality of Service，QoS)。如果因为信道过载，用户可获得的QoS低于门限值，则认为接入暂时受到限制，用户等待一段时间后再尝试通过该信道接入，或者尝试选择其他资源块对应的信道接入；否则，认为接入不会因为资源块过载的原因受到限制。
在一个应用性的实施方式中，基站的不同资源块归属不同，限制不同归属的用户接入。
一个卫星基站可以生成几十个波束，且每个波束的直径可达几十到几百公里。因此，一个卫星基站可以覆盖很大的面积，从而出现不同波束位于不同国家的情况。若不同国家的运营商不同，则每个国家对应的波束需要限制其他国家用户的接入，故基于波束的接入限制是必须的。
在这种情况下，接入限制可以由基站或用户发起。
方式一：由基站发起。在初始接入及切换时，基站首先向用户传递其所处波束的信息，包括该波束所支持的PLMN列表。如果用户可以接入的PLMN不在支持的PLMN列表中，则认为接入受到限制，用户停止从该波束接入网络；否则，认为接入不会因为PLMN不支持的原因受到限制。
方式二：由用户发起。在初始接入及切换时，用户通过预存信息判断所处波束所支持的PLMN。如果用户可以接入的PLMN不在支持的PLMN列表中，则认为接入受到限制，用户停止从该波束接入网络；否则，认为接入不会因为PLMN不支持的原因受到限制。
