如背景技术所言，对于广播/组播业务的RRC建立/重建立过程，现有技术尚无对应的接入控制方案，影响通信服务可靠性。
为解决上述技术问题，本发明实施例提供一种接入控制方法，包括：根据待传输数据的业务类型确定传输方式；根据确定的传输方式选择对应的接入控制参数进行接入控制；其中，传输方式包括单播传输方式和组播/广播传输方式，不同的传输方式对应不同的接入控制参数。
采用本实施例方案，能够在发起业务时根据采用不同传输模式的业务选择不同的接入控制参数，从而实现不同的接入控制，利于改善组播/广播服务的可靠性。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种接入控制方法的流程图。本实施例方案可以应用于用户设备侧，如由用户设备侧的UE执行。本实施例方案可以应用于下行数据传输场景，如应用于广播/组播业务触发的RRC连接建立/重建立应用场景。
在具体实施中，下述步骤S101～步骤S102所提供的接入控制方法可以由用户设备中的具有RRC连接建立或重建立功能的芯片执行，也可以由用户设备中的基带芯片执行。
具体地，参考图1，本实施例所述接入控制方法可以包括如下步骤：
步骤S101，根据待传输数据的业务类型确定传输方式；
步骤S102，根据确定的传输方式选择对应的接入控制参数进行接入控制；
其中，传输方式包括单播传输方式和组播/广播传输方式，不同的传输方式对应不同的接入控制参数。
例如，在所述步骤S101中，可以根据待传输数据的业务类型确定采用单播传输方式，还是采用组播/广播传输方式。以及，若采用组播/广播传输方式，则UE是否需要进入RRC连接态。
进一步地，所述待传输数据为待接收的下行数据。
在一个具体实施中，所述接入控制参数可以包括非接入层(Non-access stratum，简称NAS)接入控制参数以及接入层(access stratum，简称AS)接入控制参数。
具体地，不同的传输方式对应不同的NAS层接入控制参数。
进一步地，不同的传输方式对应不同的AS层接入控制参数。
在一个具体实施中，各传输方式对应的接入控制参数可以是通过协议配置的方式获取的。
例如，协议中配置采用单播传输方式传输的业务与NAS层接入控制参数之间的映射关系，还另外配置采用组播/广播传输方式传输的业务与NAS层接入控制参数之间的映射关系。
对于某一业务类型，UE可以映射出两套NAS层接入控制参数。也即，一套参数对应单播方式的数据传输，另一套参数对应组播/广播方式的数据传输；
进一步，UE在AS层进行接入控制时，根据数据的传输方式来选择对应的NAS层接入控制参数。
例如，若是通过单播方式进行数据传输，则UE选择对应单播方式的映射表来得到NAS层接入控制参数；
又例如，若是通过组播/广播方式进行数据传输，则UE选择对应组播/广播方式的映射表来得到NAS层接入控制参数；
在一个具体实施中，所述NAS层接入控制参数可以包括接入类型(access category)和一个或多个接入ID(access identity)的映射关系表。
进一步的，通过配置组播/广播方式的业务和NAS层接入参数的映射关系，还可以指示终端通过组播/广播接收所述业务需要在RRC连接态进行。例如，所述业务类型包括需要在RRC连接态下使用组播/广播传输方式进行数据传输的业务类型。根据该业务类型所采用的组播/广播传输方式是否存在对应的NAS层接入参数，UE可以判断本次数据传输是否需要在RRC连接态进行。
由此，采用本实施方案，UE可以在发起业务时，可以根据采用的不同传输模式的业务选择不同的NAS层接入参数，从而实现不同的接入控制。
在一个具体实施中，各传输方式对应的接入控制参数可以是通过核心网配置的。
具体地，对于采用组播/广播传输方式传输的业务，核心网可以通过NAS信令通知终端业务和NAS层接入控制参数的映射关系。由此，终端可以得到组播/广播传输方式传输的业务对应的NAS层接入控制参数。
例如，核心网可以在组播通告(multicast announcement)、UE重注册(registration)等过程中将采用组播/广播传输方式传输的业务和NAS层接入控制参数的映射关系通知到终端。
进一步，UE在AS层进行接入控制时，可以根据将要传输的数据的传输方式来选择对应的NAS层接入控制参数。
例如，若是通过单播传输方式进行数据传输，则UE选择对应单播传输方式的映射表来得到NAS层接入控制参数。
又例如，若是通过组播/广播传输方式进行数据传输，则UE选择对应组播/广播传输方式的映射表来得到NAS层接入控制参数。
由此，采用本实施方案，UE可以在发起业务时，根据采用的不同传输模式的业务选择不同的NAS层接入参数，从而实现不同的接入控制。
在一个具体实施中，各传输方式对应的接入控制参数可以是通过系统消息获取的。
具体地，基站为采用组播/广播传输方式传输的业务配置一套AS层接入参数，所述AS层接入控制参数可以包含uac-BarringFactor，用于指示接入概率。所述AS层接入控制参数还可以包含uac-BarringTime，用于计算同一接入类型的一次接入失败后到下次接入尝试程序的最小时间间隔。所述AS层接入控制参数还可以包含uac-BarringForAccessIdentity，用于指示每一接入ID是否允许被接入。
进一步地，所述AS层接入控制参数可以通过系统信息发送。
进一步地，UE可以从系统信息中分别获得接入类型对应的单播 传输方式对应的AS层接入控制参数，以及对应的组播/广播传输方式对应的AS层接入控制参数。
在一个具体实施中，UE在进行接入控制时，对于同一接入类型，不同的传输方式可以对应不同的AS层接入参数。
例如，若步骤S101确定采用单播传输方式，则步骤S102在进行接入控制时，采用系统信息中对应于单播传输方式的AS层接入控制参数执行接入控制相关操作。
又例如，若步骤S101确定采用组播/广播传输方式，则步骤S102在进行接入控制时，采用系统信息中对应于组播/广播传输方式的AS层接入控制参数执行接入控制相关操作。
由此，采用本实施方案，UE在AS层执行接入控制期间，对应于不同的数据传输方式，可以采用不同的接入控制参数进行接入控制。
在一个具体实施中，所述组播/广播传输方式对应的AS层接入控制参数可以是在所述单播传输方式对应的AS层接入控制参数的基础上添加偏置得到的。由此，协议、核心网或基站无需配置两套不同的接入控制参数，而是在现有单播传输方式对应的接入控制参数的基础上，以添加一定偏置的方式得到用于组播/广播传输方式的接入控制参数。
例如，组播/广播传输方式对应的uac-BarringFactor可以是由单播传输方式对应的uac-BarringFactor加第一偏置(offset1)得到的。
或者，组播/广播传输方式对应的uac-BarringFactor可以是由单播传输方式对应的uac-BarringFactor乘以第二偏置(offset2)得到的。
又例如，组播/广播传输方式的uac-BarringTime可以是由单播传输方式对应的uac-BarringTime加上第三偏置(offset3)得到的。
在一个具体实施中，UE可以从系统消息获得单播传输方式对应 的接入控制参数，然后通过添加相应偏置的方式计算得到组播/广播传输方式对应的接入控制参数。
例如，在执行所述步骤S102时，若是单播传输方式，则采用接入类型对应于单播传输方式的AS层接入控制参数执行接入控制。
若是组播/广播传输方式，则采用接入类型对应于单播传输方式的AS层接入控制参数加上一定偏置后得到的数值执行接入控制。
在一个典型的应用场景中，UE可以根据待传输数据的业务类型确定传输方式，并根据确定的传输方式从协议、核心网或系统消息配置的多套映射关系表中选择本次传输方式对应的映射关系表。所述映射关系表包括一个或多个接入ID与接入类型的NAS层接入参数。
例如，UE的NAS层通过表映射方式，通过业务得到NAS层接入参数，或者核心网通过信令通知UE优先级、业务标识、QoS、slice等信息和NAS层接入参数的映射关系。
进一步，UE在执行步骤S102时，根据接入类型，可以通过系统消息得到AS层接入控制参数，从而进行接入确认(access check)过程。
在接入控制过程中，若UE从NAS层得到的一个或多个接入ID，其对应的uac-BarringForAccessIdentity至少有一个为0，则接入通过；否则，UE产生随机数与门限值比较，若低于门限值uac-BarringFactor，则接入通过，否则接入不通过。
若接入被拒绝，则产生一个随机数rand，并启动定时器T390，该定时器T390超时后，可再次发起接入控制；其中，T390＝(0.7+0.6*rand)*uac-BarringTime。
由上，采用本实施例方案，能够在发起业务时根据采用不同传输模式的业务选择不同的接入控制参数，从而实现不同的接入控制，利于改善组播/广播服务的可靠性。
