具体实施方式
为了更好的理解本公开实施例公开的一种接入控制方法，下面首先对本公开实施例适用的通信系统进行描述。
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开实施方式作进一步地详细描述。
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
请参见图1，图1为本公开实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本公开实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101、一个终端设备102为例。
需要说明的是，本公开实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。
本公开实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、传输接收点(transmission reception point或transmit receive point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本公开的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本公开实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本公开实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本公开的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
上述通信系统中，当终端设备需要连接网络时，需要首先进行统一的接入控制检测，如果接入控制检测失败，会启动定时器T390，在定时器T390运行期间，禁止该终端设备向网络发起接入。在定时器T390运行期间，如果处于空闲态或者非激活态的终端设备进行了小区重选，则停止定时器T390。
终端设备可以不直接与网络设备连接，而通过另外一个终端设备的中继，来实现与网络设备的通信，其中，未与网络设备连接的终端设备称为远端(remote)终端设备，提供中继功能的终端设备称为中继(relay)终端设备，远端终端设备与中继终端设备之间通过侧行链路(sidelink)单播通信。
其中，当远端终端设备通过中继终端设备与网络设备建立连接时，也需要进行统一的接入控制检测。
其中，中继终端设备和远端终端设备可以处于RRC(radio resource control，无线资源控制)空闲状态或者非激活状态，当远端终端设备有数据需要中继时，可以触发中继终端设备建立RRC连接，进入RRC连接态。
目前，当远端终端设备通过中继终端设备驻留到一个小区时，如果接入控制检测失败，会启动定时器T390。但是，如果远端终端设备进行了小区重选，选择的小区还是之前通过中继驻留的小区，此外，如果远端终端设备进行中继重选，通过新中继驻留的小区还是之前通过旧中继驻留的小区，在这种情况下，远端终端设备会停止定时器T390，导致接入控制失效，进而造成网络拥塞。
针对上述问题，本公开提供了接入控制方法及装置。
可以理解的是，本公开实施例描述的通信系统是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
