具体实施方式
下面结合附图和实施例对本申请进行说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本申请，而非对本申请的限定。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。另外 还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。
在NR系统中，可以根据终端的接入类型(Access Category)或接入识别码(Access Identity)，对终端进行统一接入控制(Unified Access Control，UAC)。对于接入类型，共定义了64个分类，其中，Category 0～8可应用于NR的接入控制；对于接入识别码，共定义了16个分类，其中，0～3、11～15分类可应用于NR的接入控制。
REDCAP终端相比于NR系统中的其他终端，服务优先级较低，获得相同的数据速率所需的带宽资源更多。如果对REDCAP终端和NR系统中的其他终端，都采用统一的方式进行接入控制，则REDCAP终端占用较多的带宽资源，无法保证通信效率和整个系统的性能，REDCAP终端的接入对已部署终端的通信质量造成影响。
在本申请实施例中，提供一种接入控制方法，可应用于第一网络节点，第一网络节点例如为用户终端(User Equipment，UE)，包括REDCAP终端。第一网络节点根据所属的终端类型确定目标接入控制参数，并据此确定是否允许接入，从而实现对不同类型终端分别进行接入控制，提高接入控制的灵活性和可靠性。
图1为一实施例提供的一种接入控制方法的流程图，如图1所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，根据所属的终端类型，获取目标接入控制参数。
本实施例中，终端可以分为REDCAP终端以及非REDCAP终端，还可以分为采用NR的接入控制参数进行统一接入控制的终端以及采用为REDCAP终端单独配置的接入控制参数进行接入控制的终端等。第一网络节点根据其所属的终端类型，获取对应的目标接入控制参数，作为接入控制的依据，其中，目标接入控制参数用于指示第一网络节点所属的终端类型对应的接入控制信息，即， 指示该终端类型的第一网络节点是否被允许接入。各终端类型对应的目标接入控制参数可由第二网络节点(例如为基站)配置并传输至第一网络节点。
在步骤120中，根据所述目标接入控制参数确定接入控制信息，所述接入控制信息包括允许接入或禁止接入。
本实施例中，第一网络节点根据获取到的目标接入控制参数完成接入控制的检查，即，确定第一网络节点是允许接入还是禁止接入，如果是允许接入，则第一网络节点在当前所处的目标小区中发起随机接入。
在一实施例中，通过以下方式使能第一网络节点的接入控制：第二网络节点在主信息块(Master Information Block，MIB)中配置各小区是否允许接入的指示信息，例如，在第一网络节点所处的目标小区指示为barred状态的情况下，第一网络节点认为该目标小区的禁止接入的，不需要继续读取与接入控制相关的参数，也不需要再进行接入控制的检查；在目标小区指示为允许接入的情况下，第一网络节点可以继续读取系统信息块(System Information Block，SIB)SIB1中相关的配置信息，根据目标接入控制参数完成接入控制的检查等，在此基础上，如果目标接入控制参数对应的接入控制信息为允许接入，则第一网络节点可以在目标小区发起随机接入。
在一实施例中，第一网络节点为REDCAP终端，对于REDCAP终端，有以下两种方式使能REDCAP终端的接入控制：第一种是第二网络节点在MIB中配置的指示信息同样适用于REDCAP终端，REDCAP终端需要先读取该指示信息，然后根据目标小区指示的状态是否为barred，确定是否要进一步读取相关配置和目标接入控制参数并判断是否允许接入；第二种是，对REDCAP终端额外增加是否允许接入的指示信息，并且该指示信息只有在NR的目标小区指示为允许接入的情况下才起作用，即，如果NR的目标小区指示为barred状态，则REDCAP终端也认为该目标小区是barred状态，而如果NR的目标小区指示为允许接入，则进一步根据该额外增加的指示信息是否为barred状态，确定是否要进一步读 取相关配置和目标接入控制参数并判断是否允许接入。
在一实施例中，REDCAP终端关联于接入控制分类的目标接入控制参数相关配置，可以配置于独立的SIB消息中，例如新引入的SIB消息为SIB1-REDCAP，这种情况下，REDCAP终端需要读取SIB1-REDCAP进行接入控制的检查，如果允许接入，则继续读取其他的SIB消息。
在一实施例中，还包括：
步骤101：根据终端类别信息与终端能力信息中的至少之一确定所属的终端类型。
本实施例中，可以根据第一网络节点的带宽能力确定终端所述的终端类型，例如，支持不同带宽的终端分别对应于不同类别的能力降低终端；或者，也可以根据第一网络节点上报的能力降低终端的类别直接确定。
在一实施例中，第一能力降低终端和第二能力降低终端对应的目标接入控制参数的数量可以相同，也可以不同。
在一实施例中，终端类型包括能力降低的终端类型和非能力降低的终端类型。
本实施例中，区分REDCAP终端和非REDCAP终端，分别进行接入控制。REDCAP终端对应的目标接入控制参数和接入控制信息，可以与非REDCAP终端的相同，也可以不同。
在一实施例中，目标接入控制参数关联的接入控制分类包括NR的接入控制分类中的预留分类。
本实施例中，目标接入控制参数关联的接入控制分类包括NR的Access Category中的预留分类。在第一网络节点为REDCAP终端的情况下，可以将NR的Access Category中的预留分类应用于对REDCAP终端的分类，即，根据NR的Access Category中的预留分类，将相同的参数配置和定义应用于对REDCAP 终端的接入控制参数配置。例如，NR的Access Category中的预留分类包括Category9～31，将其中的Category9～17用于对REDCAP终端的接入控制参数配置。
在一实施例中，目标接入控制参数关联的接入控制分类包括NR的接入控制分类中的已用分类。
本实施例中，目标接入控制参数关联的接入控制分类包括NR的Access Category中的已用分类，在第一网络节点为REDCAP终端的情况下，可以将NR的Access Category中的已用分类可用于对REDCAP终端的分类，并且还可以为各已用分类增加指示信息以指示REDCAP终端是否允许接入。
在一实施例中，还包括：步骤102：获取已用分类对应的n比特指示信息，指示信息用于指示目标接入控制参数关联的已用分类对应的接入控制信息，其中，n为1或2或3或4。
本实施例中，在第一网络节点为REDCAP终端的情况下，将NR的Category 0～8用于配置REDCAP终端的目标接入控制参数，且分别为Category 0～8增加n bit的指示信息，用于指示每个终端类型对应的接入控制信息为允许接入或禁止接入，或者指示每个终端类型是否具有与NR的Category一致的barred状态。其中，n bit的指示信息仅适用于REDCAP终端，而对于NR中其他终端不起作用。
本实施例中，已用分类对应于n比特指示信息，用于指示目标接入控制参数关联的已用分类对应的接入控制信息，其中，n为1或2或3或4。
