请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户 单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空 口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
根据R15中NR接入控制(access barring)的结论，现有的接入控制(AC barring)参数的结构是针对每个公共陆地移动网络(Public Land Mobile Network，PLMN)、每个接入类别、每个接入标识提供。下表给出一个示范例，其中PLMN的最大数目为6，接入类别和接入标识的最大数目分别为64和16。
[根据细则26改正10.10.2020]　
表1 为AC参数示例，(AC参数可以理解为AC barring参数)。
Figure PCTCN2020113833-appb-000001
Figure PCTCN2020113833-appb-000002
根据3GPP TS 24.301，接入类别可包括以下至少之一:
主动信令传输("originating signalling")；
紧急呼叫(“emergency calls”)；
发起VoLTE语音呼叫("originating MMTEL voice")；
发起VoLTE视频呼叫("originating MMTEL video")；
发起SMSo IP呼叫("originating SMSoIP")；
发送短信("originating SMS")；
被叫("terminating calls")；
主叫("originating calls",)；
电路回落的移动主叫("mobile originating CS fallback")。
而接入标识(Access identities)即用户标识的一种，则可以理解为UE的属性，比如0-9为普通用户，11-15为高优先级用户。
表格中AC barring参数的定义其定义如下所示，其中针对非特殊用户标识定义了随机数和barring生效时长；而对于特殊用户标识的业务则采用bitmap形式。
Figure PCTCN2020113833-appb-000003
所以基本的接入控制(AC barring check)的过程就是决定用户设备的接入类型(Access categories)，得到AC barring参数，进行AC barring check。AC barring参数对于普通用户(0-9)通常采用随机数，而对于高优先级用户(11-15)，则采用bitmap形式。
在一个实施例中，AC参数将通过在SIB1即通RMSI中定义。
在目前的3GPP标准化中，提出了新的终端类型叫做能力缩减(Reduced capability)UE或者简称为NR-lite或者Redcap终端。该类设备同LTE中的物联网设备类似，基于5G NR-lite中的通常需要满足如下要求：低造价，低复杂度；主要应用场景为工厂传感器(sensor)，或者视频监控以及可穿戴设备。对于前面两种设备类型而言通常是在网络中大量密集部署。从目前的讨论结果看，大部分公司达成共识需要为Redcap的特定终端类型，比如工厂接入标识的场景引入新的接入标识(Access identities)。甚至可能为细化的接入标识类型引入更多的接入标识(Access identities)。
如果按照现有机制，对于接入标识(Access identities)而言，采用比特位图(bitmap)的形式，则会造成但网络对于AC参数有变更，比如从原来的0->1这种翻转，则Redcap用户收到系统消息更新的指示之后，会在系统 消息修改的边界获取SIB1，则会出现大量用户同时在系统消息修改边界进行更新，于是，大量用户同时发起呼叫而导致业务量突发，从而导致网络的拥塞。因此本文即针对Redcap类型的的UAC进行了增强。
如图2所示，本公开实施例一种接入控制方法，包括：
S110：控制预设用户设备UE在不同时机发起接入。
所述预设UE可为各种类型可接入蜂窝移动通信网络的通信终端，具体可为：各种智能设备。所述智能设备包括但不限于以下至少之一：
智能家电设备，典型的智能家电设备可包括：智能水表、智能电表、智能燃气表和或居家监控设备；
工业传感设备，工业传感设备包括但不限于：制作监控设备；
道路监控设备，例如，各种路口的监控器；
小区或厂区的安防设备，例如，视频和/或音频监控器。
这些设备大多数时刻能没有很多数据要上报，一般处于空闲态或非激活态等低能耗的状态，有少量数据也缓存这，在缓存了足够多的数据或者达到的上报周期时才上报数据。
举例来说，在一个小区内若每一户都安装：智能水表、智能电表及智能燃气表，由于设备类型相似，且涉及的业务也相似，因此极大可能具有相同的接入等级。例如，一个小区的所有楼房在同一个小区的覆盖范围内，这个小区的用户很多，安装的智能设备也很多。例如，有多达500个智能水表，若这个500个智能水表同一个时间发起接入，此时，有非常大的概率导致接入拥塞。因此，这若基于相同的接入等级进行接入控制之后，再发起随机接入，依然会导致大量的接入拥塞。
因此，在本公开实施例中，为了减少大量预设UE涌入的接入拥塞，会控制具有相同接入等级预设UE，在不同时机发起接入，从而实现具有相同接入等级的预设UE能够在不同时机分批接入，从而减少上述拥塞现象，减 少因为拥塞导致的短时间内的无线网络侧的业务拥堵现象，实现接入网侧的负载均衡及业务传输质量。
在一个实施例中，所述预设UE可为具有相同或相似终端属性的一个或多个类别的UE，或者，具有相同或相似业务属性的一个或多个类别的UE。
在一些实施例中，所述预设UE包括：轻型能力Redcap UE。
Redcap UE是相对于用户的手机或者可穿戴式设备等增强移动带宽
Redcap UE大量使用在智能家居领域、道路监控领域、安防领域或者工业制作领域。因此，Redcap UE是属于上述预设UE的一种。
预设UE接入按照原因可有多种，以下提供可选地两种：
第一种：业务数据传输触发的接入；
第二种：系统消息更新触发的接入。
针对业务数据传输引起的所述接入；所述预设UE为具有相同接入等级，且接入控制AC参数为：采用比特位图指示所述接入等级接入等级的UE。在本公开实施例中，预设UE并非针对于所有的采用比特位图通过接入等级实现接入控制的UE，而是针对可能大规模数量的UE，例如，各种应用场景下广泛使用的物联网设备，而针对少量基于比特位图通过接入等级进行接入控制的UE，为了抑制接入拥塞可以尽量采用吧本公开实施例的方法，进一步在不同的时机进行接入，减少接入拥塞。
在本公开实施例中，比特位图指示的AC参数至少包括：允许接入的介入等级的指示信息。例如，比特位图共有N个比特，N个比特中的任意一个比特对应于一个接入等级；一个比特的两个比特值，可分别用于指示这两个接入等级的允许接入和禁止接入两个可能。
针对系统消息更新引起的所述接入，所述预设UE为小区内任何需获取更新后的系统消息的任意UE。例如，针对系统消息更新引起的所述接入，所述预设UE为小区内任何需获取更新后的系统消息的任意两个RedCap  UE。
具体的打散这些预设UE的接入可以采用如下方式的任意一种：
触发预设UE接入的通知消息，在不同时机发，因此，预设UE在接收到通知消息之后，会在不同的时机获取更新后的系统消息。一方面可以打散因为系统消息更新引起的接入，另一方面携带有AC参数的系统消息的获取时机打散了，同时相当于具有相同接入等级的UE会在不同的时间点获取由系统消息携带的更新后的AC参数，因此基于相同的AC参数集中发起的业务数据传输触发的接入也打散了。
引入打散接入的时域参数，例如，在基于AC参数的接入控制之后，在时域上引入一个或多个参数，以不同的接入延迟控制，控制预设UE的接入发起；这种时域参数可包括：一个或多个延迟值，这些延迟值的引入，可以打散获取更新后的系统消息的接入，也可以打散业务数据传输的接入，从而减少不同原因触发的集中接入，减少拥塞。
再例如，可以控制UE借助下一次业务触发的接入来获取更新后的系统消息，而非单独因为系统消息更新就发起接入，因为业务触发接入的时机有比较大的概率不同，采用这种方式就直接能够将系统消息更新触发的接入打散到不同的时机。针对这种系统消息更新，可以统一下发系统消息的更新通知，也可以不下发系统消息的更新通知。例如，统一广播系统消息的通知等，也可以干脆不下发系统消息的更新通知。
针对系统消息更新触发的接入，在相关技术中都是在接收到系统消息的更新通知之后，在接收到更新通知之后的下一个系统消息更新通知周期的时域边界位置处发起接入获取更新后的系统消息。例如，通过系统消息的通知消息，触发预设UE在接收到通知消息之后立即发起获取系统消息的接入，从而通知消息的下发时机不同，则预设UE发起获取更新后的系统消息的接入时机不同。再例如，可以通过系统消息通知的下发时机不同，使 得预设UE接收到更新通知的周期不同，从而能够打散因为获取更新后的系统消息的集中接入，从而减少接入拥塞。当然此处仅是举例，具体实现的方式不同。
基站配置的系统消息可能会更新，也可以不会更新。系统消息的更新是有系统消息更新周期的。
若在下一个更新周期，基站会更新系统消息，则在本周期可以广播或单播给用户设备在下一周期更新系统消息。若不进行打散，具有相同接入等级且采用比特位图指示的接入等级进行接入控制的UE，会在系统消息的下一个更新周期的起始时刻，获取到系统消息后，集中发起因为业务数据传输触发的接入，这显然有极大的可能会导致接入拥塞。
在本公开实施例中，基站侧会控制预设UE的接入，即通过系统消息更新在不同时机发起，而非集中在下一个更新周期的起始时刻附近。
针对一些预设UE中的特定UE，可能会周期性苏醒，并从空闲态或非激活态切换到连接态，请求接入并上传业务数据。若大量预设UE具有相同的传输周期，则可能有大量预设UE在同一个时刻发起接入，为了减缓这种集中接入导致的拥塞，会进一步打散预设UE在同一个时机的集中接入，从而减少接入拥塞。
在一个实施例中，所述系统消息的更新，包括：AC参数引起的系统消息更新。
所述系统消息包括：系统消息块SIB 1；和/或系统消息块SIB m，其中，所述m为等于或大于2的正整数。
基站侧为了控制预设UE的接入，可能会更新AC参数；而AC参数是携带在系统消息块中的，如此，AC参数的更新就会导致系统消息的更新。
该AC参数包括但不限于：接入类别、接入等级和/或接入禁止定时器的定时时长等。
该AC参数可以携带在SIB1中，也可以携带在SIBm。
例如，SIB1是广播消息，在空闲态和非激活态下都可以接收广播消息，若将AC参数携带在SIB1中，预设UE在SIB1的广播时间窗接收SIB1即可。但是若SIB1更新后的AC参数，会使得预设UE在经过AC参数的接入控制后，发现可以接入，且预设UE内已经缓存了一些待上报业务数据和/或达到了上报时刻，则SIB1的这种广播依然会导致预设UE集中接入的拥塞。
在另一个实施例中，AC参数可以携带在SIBm中，该SIBm可为SIB以外的其他任意一个SIB，例如，可以基于请求获取的SIB(即on demanded SIB)。若AC参数携带在on demanded SIB中，由于具有相同接入等级的预设UE有比较大的概率会在不同的时机发送请求获取更新后的AC参数，因此，即便更新后的AC参数允许UE接入，且此时达到了业务上报周期或者有触发接入的事件发生，由于不同预设UE获取AC参数的时间被打散了，则具有相同接入等级的预设UE还是会在不同的时机发起基于业务数据传输触发接入。
总之，所述预设UE的AC参数可携带在所述SIB1或所述SIM m中。
在一个实施例中，所述SIMm为携带所述预设UE的AC参数的专用系统消息块。
为了进一步减少接入等级相同的预设UE在同一个时机发起接入，设置一个专用系统消息块下发AC参数，该系统消息块可为一个on demanded的SIB。
在一个实施例中，所述S110可包括：
采用寻呼(paging)下行控制信息(Downlink Control Information，DCI)携带指示所述系统消息更新的更新通知。
由于不同的UE的寻呼DCI是在不同的寻呼时机(Paging Occasion， PO)，相当于在不同的时机通知具有相同等级的预设UE的系统消息更新。不同的寻呼时机发送的寻呼DCI，会对应不同的接入时机。例如空闲态或非激活态的UE，一般接收到寻呼DCI之后会立即获取更新后的系统消息再发起基于待传输业务数据触发的接入，此时，因此通过更新通知的打散下发，就相当于控制具有相同等级的预设UE会在不同的时机接入。
在一个实施例中，所述寻呼DCI还携带有类型指示；所述类型指示，指示需在接收到寻呼DCI立即发起获取更新后系统消息的所述预设UE的类型。
在寻呼DCI内还包括一个或多个比特，指示接收到寻呼DCI立即发起接入的预设UE的类型。
例如，智能家居设备、监控设备和/或工业传感器，都属于相同的接入等级的预设UE，具体哪个类型的预设UE接收到寻呼DCI之后立即发起呼叫，去获取更新后的系统消息，可以进一步分化。
例如，在一个寻呼时机还是很多预设UE都可以接收到寻呼DCI，则通过类型指示，仅允许部分类别的预设UE接收到寻呼DCI立即发起接入，请求更新后的系统消息。而剩余部分的预设UE可以采用其他方式确定接入时机，并在接入之后获取更新后的系统消息。例如，剩余部分的预设UE，可以在系统消息的下一个更新周期的起始时刻请求接入，并在接入后获取系统消息。剩余部分的UE也可以是在借用下一次业务触发的接入之前，请求系统消息，并在请求到更新后的系统消息之后，进行业务传输。若此时更新后的系统消息携带有AC参数，将进一步根据更新后的AC参数，重新确定是否不是发起业务触发的接入。
在一些实施例中，如图2所示，所述S110可包括：
步骤S111：不同类型的所述预设UE独立配置接入的延时值，其中，所述延时值，用于在所述预设UE通过接入控制AC参数的接入控制之后的 接入的延迟时长。
为了将具有相等接入等级且采用比特位图指示AC参数的所有UE被认定预设UE，为了实现这些预设UE的接入打散，则为了引入了不同的延时值。例如，延时值可为按照随机算法随机生成的随机值。若该随机值为0到1之间的任意一个数据。若将0到1设置100个随机数，则可以将预设UE的接入时机打散到100个接入时机上。
例如，预设UE又可以分为很多类别，同一个类别的UE可以具有相同的延时值，而不同的类型的预设UE因为具有独立的延时值，可以设置相同，也可以设置不同。在本公开实施例中，为了进一步打散预设UE在同一个时间点的集中接入，不同类型的预设UE可具有不同的延时值。
在一个实施例中，由于接入等级相同，因此会基于相同的AC参进行接入控制，因此具有相同接入等级的预设UE都会接入通过。再通过独立的延时值的延迟之后，就可以打破预设UE的集中接入，实现预设UE的分散接入。
在本公开实施例中，通过延时值的不同，则按照不同的延时值进行接入，因此在下发触发预设UE发起接入的业务数据传输或者系统消息更新等的通知可以在不同的时机发送也可以在相同的时间发送。
在一些实施例中，如图2所示，所述方法，包括：
S120：通过广播消息下发所述延时值；或者，通过专用消息单播所述延时值。
在一个些实施例中，延时值可以预先规定在通信协议中，也可以预设由UE和基站之间协商，也可以由基站下发。
在本公开实施例中，延时值的下发由广播消息下发的，组播消息下发，或者由专用单播消息下发。
专用单播消息包括但不限于：无线控制连接(Radio Control Cnnection， RRC)消息等。
在一些实施例中，所述控制具有相同接入等级的预设用户设备UE在不同时机发起接入，包括：
控制所述预设UE发起业务传输之前接入获取更新后的所述系统消息。
在本公开实施例中，由于预设UE在接收到系统消息的通知消息之前，或者没有接收通知消息的情况下，都每次或者间隔一定次数之后，发送业务传输之前的接入之后，不直接传输业务数据，而是先请求是否有更新后的系统消息，若有更新后的系统消息，则基站返回出更新后的系统消息。预设UE再根据更新后的系统消息中的AC参数进行接入控制，并进行基于业务数据传输触发的接入。
由于预设UE的发送业务传输的需求不会全部集中，因此，在有业务传输触发接入时，利用该业务传输触发的接入作为获取更新后的系统消息的接入，从而至少打散了因为系统消息更新触发的集中接入。
进一步地，若预设UE发起业务传输之前接入，去获取更新后的系统消息，在这种情况下，针对预设UE的系统消息的更新通知都可以不用下发，从而进一步减少信令。
如图4所示，本公开实施例提供一种接入控制方法，其中，应用于接入控制AC参数为：采用比特位图指示接入等级的预设UE中，包括：
S210：根据所述AC参数发起接入，其中，至少部分所述预设UE发起所述接入的时机不同。
本公开实施例应用于预设UE中。
针对业务数据传输引起的所述接入；所述预设UE为具有相同接入等级，且接入控制AC参数为：采用比特位图指示所述接入等级接入等级的UE。
针对系统消息更新引起的所述接入，所述预设UE为小区内任何需获取 更新后的系统消息的任意UE。
上述任意一种原因导致的接入所针对的预设UE均可为RedCap UE。
基站会控制具有相同接入等级的预设UE在不同的发起时机发起，但是在预设UE侧而言，针对业务数据传输发起的接入，预设UE还是会根据AC参数发起接入。只是，由于基站的控制，至少部分预设UE的发起接入的时机是不同于其他预设UE的。此处的接入可以称之为随机接入。
由于减少了在同一个时机发起接入的预设UE的数量，从而减少大量预设UE同时接入发起导致的拥塞现象。
在一些实施例中，如图5所示，所述方法还包括：
S200：接收所述系统消息更新的更新通知；
所述S210可包括：
S210：根据所述AC参数，在接收到所述更新通知之后立即发起获取更新后系统消息的接入。
在另一个实施例中，所述更新后的系统消息携带有更新后的AC参数；
根据所述更新通知，立即获取更新后的系统消息；所述根据所述AC参数发起接入，包括：
根据更新后的所述AC参数，在获取到更新后的系统消息之后，发起待传输业务数据触发的接入。
在一个实施例中，携带所述AC参数的系统消息块为：系统消息块SIB1；和/或系统消息块SIB m，其中，所述m为等于或大于2的正整数。
此处的SIMm可为on demanded的系统消息块。
在一些实施例中，所述接收系统消息的更新通知，包括：
接收携带有所述更新通知的寻呼DCI。
在本公开实施例中，系统消息更新的更新通知是携带在寻呼DCI内的，由于即便是具有相同接入等级的预设UE的寻呼时机也是被打散的，从而通 过系统消息的更新通知的打散，就减少了具有相同接入等级的预设UE基于比特位图指示的AC参数进行接入控制，同时发起接入的预设UE的数量。
在一些实施例中，
所述寻呼DCI还携带有类型指示；
所述类型指示通知指示立即获取更新后的所述系统消息的所述预设UE的类型。
在本公开实施例中，该寻呼DCI携带有类型指示，相当于通过寻呼DCI指定特定类型的预设UE允许接入，通过类型指示限定特定类型的预设UE禁止接入，从而通过类型指示可以进一步减少具有相同等级的预设UE的集中接入。
在一些实施例中，所述根据所述更新通知，发起获取更新后系统消息的接入，包括：
响应于所述类型指示通知指示无需立即获取更新后的所述系统消息，在接系统消息的下一个更新周期起始时刻发起获取更新后的所述系统消息的接入。
在本公开实施例中，若寻呼DCI内携带的类型指示，指示后一部分预设UE无需在接收到寻呼DCI之后立即发送获取更新后系统消息的接入，这一部分预设UE则可以在系统消息的下一个更新周期获取发起接入，获取更新后的系统消息。
在一些实施例中，所述根据所述AC参数发起接入，包括：
根据AC参数，进行接入控制；
在根据接入控制的结果确定接入之后，延时等于延时值的延时之后发起接入。
针对预设UE，再根据AC参数进行接入控制，而接入的结果分为两种，一种是确定接入，一种是禁止接入。若确定接入之后，不会立即发起接入， 而是会延迟等于延时值的时长之后再发起接入，如此，通过延迟值可以将具有接入等级且通过比特位图指示AC参数的预设UE，会分批在不同的时机发起接入。
在一些实施例中，所述方法还包括：
接收携带有所述延时值的广播消息；
或者，
接收携带有所述延时值的专用消息。
若利用延迟值分别发起接入，则需要获取延时值。延时值的获取，方式有很多种。
例如，延迟值可以写入到通信协议中，预设UE可以通过查询通信协议获取，也可以从基站侧接收。基站下发该延迟值的方式有很多种，例如，通过发送广播消息，或单播专用该消息向预设UE发送延迟值。
在一些实施例中，所述根据所述AC参数发起接入，包括：
根据所述AC参数，发起基于业务数据传输之前，接入获取更新后的所述系统消息。
根据AC参数发起有业务数据触发的接入，作为获取更新后的系统消息的接入。由于业务数据传输的随机性，从而能够打散获取更新后的系统消息的接入。
如图6所示，本公开实施例提供一种接入控制装置，包括：
控制模块110，被配置为预设用户设备UE在不同时机发起接入。
本公开实施例提供的接入控制装置，可应用于基站中。
该控制模块110可用于通过通知下发和/或包含延时值等配置来控制具有相同接入等级且利比特位图指示AC参数的预设UE，在不同的时机发起接入。

在另一个实施例中，控制模块110可为软硬结合模块；所述软硬结合模块可为各种可编程阵列；所述可编程阵列包括但不限于：现场可编程阵列或复杂可编程阵列。

在一些实施例中，所述预设UE包括：轻型能力Redcap UE。

在一些实施例中，所述系统消息的更新，包括：
AC参数引起的系统消息更新。
在一些实施例中，所述系统消息包括：
系统消息块SIB 1；

针对AC参数采用比特位图(bitmap)下发的用户设备(即用户)在进行系统消息更新时，采用分散的方式发起接入。
一种实施例为采用比特位图指示AC参数的UE为Redcap终端。
为了达到使得Redcap UE等分散在不同的时机发起获取更新后系统该消息的请求，以下提供几种可选方式：
可选方式一：
对采用比特位图指示AC参数的UE，其系统消息更新方式为即时更新方式：
在即时更新方式下，UE接收到系统消息的更新通知之后，立即发起呼叫(接入)，以从空闲态或非激活态切换到连接态，在切换到连接态之后，在RRC连接上请求基站发送更新后的系统消息。
当然，若此时UE在连接态下，接收到指示系统消息更新的通知，可以直接立即在已建立的RRC连接上发送获取请求，以获取更新后的系统消息。
接收到更新通知之后立即发起接入请求更新后的系统消息这种方式下，更新通知的下发方式可如下：
在现有的寻呼下行控制信息(pagingDCI)中增加指示，指示某种类型用户设备的系统消息更新的更新通知。
例如，在寻呼(paging)DCI中增加systemInfoModification-Redcap，Redcap用户设备收到该系统消息的更新通知，则马上获取更新的系统消息
Figure PCTCN2020113833-appb-000004
该方式下，因为寻呼消息(paging)已经将用户均匀分散开在不同的寻呼时机(Paging Occasion，PO)，因此在用户设备听到寻呼消息之后获取系统消息，则起到了呼叫分散的作用。
该机制可以针对特定的接入标识(Access identities)进行。即为不同类别的用户进行增强；即寻呼消息的下行控制信息(paging DCI)中为不同的类别的用户设置不同的指示比特位。
可选方式二：
系统消息的更新通知，可以采用可选方式一种的寻呼DCI来下发，可以采用现有的方式进行下发。
在本公开实施例中使得采用比特位图携带AC参数的用户设备在不同的时机发起获取更新后的系统消息的方式，可以是设置一个延迟值。
例如，接收到更新通知之后，UE依然可以在系统消息的下一个更新周期的起始时刻的边界位置处发起获取更新后系统消息的接入，但是为了减少接入拥塞，每一个预设UE都有一个延时值。不同预设类型UE的延时值独立，如此，会使得不同的预设UE会有极大概率具有不同的延时值，从而打散了预设UE基于系统消息更新发起的接入。
例如，该延时值是基站采用随机算法生成的随机数。
一种实施例为采用bitmap方式进行AC的用户设备为的不同的接入标识(Access identities)再配置一个随机延迟值，比如Nms；用户进行现有的AC barring check之后，再在0-Nms之间随机生成一个延迟值进行呼叫发起的延迟。
该随机延迟值可以用专用信令或者广播消息通知用户；一个实施例为放在寻呼下行控制信息(paging DCI)中或者系统消息中。
进一步地，为了减少对因AC参数导致SIB1更新，进而影响SIB1的更新。在本公开实施例中，对采用比特位图携带AC参数的用户设备，其AC参数挪到SIB1之外的其他SIB。
例如，一种实施例为其AC参数移动到一个专用携带这些UE的AC参数的SIB中。
这种系统消息的更新方式，可以采用基于更新通知的立即更新，还可以采用借用在基于业务数据传输触发的接入获取更新后的系统该消息。
方式三：
对采用比特位图(bitmap)方式指示其AC参数的用户设备，其AC参 数变更不会影响系统消息的变更指示；此时用户在发起基于业务数据传输的呼叫(即接入)之前获取最新的系统消息，并根据此时最新的AC参数进行判决即可。
