统一接入控制(Unified Access Control,UAC)

Figure PCTCN2019093393-appb-000002
表1
Figure PCTCN2019093393-appb-000003
表2
●UAC参数配置
接入网网元(如基站)广播与接入类别和接入标识相关的接入控制信息,UE的接入层(Access Stratum,AS)则根据接入控制信息和AS层或非接入层(Non Access Stratum,NAS)提供的接入类别和接入标识执行接入控制操作(即ACB checking)。
接入网网元广播的接入控制信息包括UAC参数,UAC参数是以接入类别为粒度(per access category)和/或以公共陆地移动网络(Public Land Mobile Network,PLMN)为粒度(per PLMN)进行配置的。UAC参数具体为UAC限制信息集(UAC-BarringInfoSet),网络侧最多配置8个UAC-BarringInfoSet,每个接入类别关联一个UAC-BarringInfoSet,总共64个接入类别(其中access category 0不需要配置)。也可以每个PLMN关联一个UAC-BarringPerCatList,进一步如果per PLMN信息不配置,则上述配置是对所有PLMN适用。
针对access category 1,配置一个辅助信息来辅助判断是否接入控制操作(即ACB checking)用于针对access category 1,该辅助信息为uac-AccessCategory1-SelectionAssistanceInfo。
●UAC机制:接入控制操作(即ACB checking)
接入控制操作基于UAC参数(即UAC-BarringInfoSet)执行,UAC-BarringInfoSet具体包含的内容如图2所示。在T390和T302都没有运行且接入类别不是access category 0的前提下,接入控制操作的执行包括如下步骤:
1)如果接入标识在uac-BarringForAccessIdentity中对应的比特(bit)设为0,表示允许接入,如果对应的bit设为1,则需要通过如下步骤2)进一步判决;
2)产生随机数字(rand),rand的范围为0≤rand<1,如果随机数字低于uac-BarringFactor,则表示允许接入,否则表示禁止接入。如果禁止接入,则产生随机数字(rand),rand的范围为0≤rand<1,启动T390且T390=(0.7+0.6×rand)×uac-BarringTime。
对于NAS层触发的事件,NAS层决定接入标识、接入类别以及接入原因(或称为原因值)。NAS层提供接入标识和接入类别给AS层,AS层负责执行接入控制操作。如果允许接入,则AS层通知NAS层,NAS层提供接入原因给AS层。基于AS层的接入控制操作的反馈,NAS层负责执行停止或允许业务传输。
对于AS层触发的事件,包括寻呼(paging)触发的事件、或者RAN通知区域更新(RAN Notification Area Update,RNAU)触发的事件,其中,
对于Paging触发的事件:接入类别为access category 0,不受接入控制操作的控制。此外,原因值被覆盖,NAS层和AS层之间交互,NAS层提供原因值。
对于RNAU触发的事件:接入类别为access category 8,接入标识需要NAS层给AS层提供,NAS层和AS层之间交互信息属于UE实现行为。原因值AS层决定为rna-Update。

EDT数据传输
在LTE中引入了EDT数据传输,在EDT数据传输过程中,UE可能始终保持在空闲(idle)状态或者悬挂(suspend)状态或者非激活(inactive)状态,完成上行和/或下行的EDT数据传输。
EDT数据传输可以采用控制面传输方案,如图3-1所示,包括如下步骤:
1、UE向eNB发送RRC早数据请求(RRCEarlyDataRequest)消息。
这里,RRCEarlyDataRequest消息也可以称为EDT数据传输请求消息,或小数据传输请求消息,或小数据包传输请求消息,或小包数据传输请求消息。
这里,RRCEarlyDataRequest消息携带如下信息:S-TMSI、establishmentCause、dedicatedInfoNAS。dedicatedInfoNAS即为EDT数据(或者称为小数据、或小数据包、或小包数据)。
2、eNB向MME发送初始UE消息(Initial UE message),初始UE消息携带NAS消息(NAS message)。
3、MME与S-GW之间修改承载(Modify Bearer)。
4、MME向S-GW发送上行数据(Uplink data)。
5、S-GW向MME发送下行数据(Downlink data)。
6a、下行NAS传输(DL NAS TRANSPORT)。
6b、建立连接(CONNECTION)。
7、eNB向UE发送RRC早数据完成(RRCEarlyDataComplete)消息。
这里,RRCEarlyDataComplete消息携带dedicatedInfoNAS,dedicatedInfoNAS即为EDT数据(或者称为小数据、或小数据包、或小包数据)。
8、MME与S-GW之间修改承载(Modify Bearer),eNB和MME之间执行S1释放流程(S1 release procedure)。
EDT数据传输也可以采用用户面传输方案,如图3-2所示,包括如下步骤:
1、UE向eNB发送RRC连接恢复请求(RRCConnectionResumeRequest)消息以及上行数据(Uplink data)。
这里,RRCConnectionResumeRequest携带如下信息:resumeID、resumeCause、shortResumeMAC-I。
2、eNB向MME发送UE上下文恢复请求(UE Context Resume Request)消息。
3、MME与S-GW之间修改承载(Modify Bearer)。
4、MME向eNB发送UE上下文恢复响应(UE Context Resume Response)消息。
5、eNB向S-GW发送上行数据(Uplink data)。
6、S-GW向eNB发送下行数据(Downlink data)。
7、MME与S-GW之间修改承载(Modify Bearer),eNB和MME之间执行S1悬挂流程(S1Suspend procedure)。
8、eNB向UE发送RRC连接释放(RRCConnectionRelease)消息和下行数据(Downlink data)。
这里,RRCConnectionRelease消息携带如下信息:releaseCause、releaseID、NCC。
需要说明的是,图3-1和图3-2是以LTE为例进行说明,NR与LTE同理,区别在于,对于NR需要将eNB替换为gNB,移动管理功能实体(MME,Mobility Management Entity)替换为接入和移动性管理功能实体(AMF,Access and Mobility Management Function),服务网关(Serving Gateway,S-GW)替换为用户平面功能实体(UPF,User Plane Function)。
对于上述两种方案的EDT数据传输,UE在没有进入连接状态就完成 了EDT数据传输,这类传输与进入连接态的数据传输不同。对于EDT数据传输,它不会占用很多的无线资源,与MBB业务的MO数据传输的RRC接入占用的无线资源不同。为此,需要针对EDT数据传输明确一种接入控制要求,本申请实施例给出了一个针对EDT数据传输的接入控制方式,使得接入控制合理有效,保证数据传输及时有效。

本申请实施例中,所述终端接收网络设备发送的第一配置信息,所述第一配置信息包括至少一个接入控制参数集。在一可选实施方式中,所述第一配置信息携带在系统广播消息中。举个例子:基站发送系统广播消息,该系统广播消息携带第一配置信息,终端从系统广播消息中获取第一配置信息,这里,第一配置信息具体为UAC参数配置,第一配置信息包括至少一个接入控制参数集,接入控制参数集可以是UAC-BarringInfoSet,UAC-BarringInfoSet的内容参照图2所示,UAC-BarringInfoSet包括如下参数:uac-BarringForAccessIdentity、uac-BarringFactor、uac-BarringTime。
在第一配置信息中,以接入类别为粒度配置接入控制参数集(即UAC-BarringInfoSet),每个接入类别关联一个接入控制参数集。
步骤402:所述终端确定EDT数据传输对应的第一接入类别,并从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集, 根据所述第一接入控制参数集执行所述EDT数据传输对应的接入控制操作。

1)所述终端的NAS层确定有EDT数据传输,向所述终端的AS层发送第一指示信息,所述第一指示信息用于指示所述EDT数据传输对应的第一接入类别和第一接入标识;
2)所述终端的AS层从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集,并根据所述第一接入标识以及所述第一接入控制参数集,执行接入控制操作。
具体地,为EDT数据传输的无线接入定义一个新的接入类别,这个新的接入类别和现有的MO数据传输对应的接入类别并存,例如定义新的接入类别为MO小数据(MO small data)的接入类别。UE NAS(即终端的NAS层)判断如果要执行一个EDT数据传输,则UE NAS指示UE AS(即终端的AS层)EDT数据传输对应的第一接入类别以及第一接入标识。UE AS根据UE NAS提供的第一接入类别、第一接入标识以及从系统广播消息中获取的第一配置信息,执行接入控制操作。具体地,UE AS根据UE NAS提供的接入类别从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集,并根据所述第一接入标识以及所述第一接入控制参数集,执行接入控制操作。接入控制操作可以参照前述UAC机制的相关描述,不再赘述。

方式二:所述EDT数据传输的无线接入关联多个接入类别,不同的接入类别对应不同的EDT接入原因。
1)所述终端的NAS层确定有EDT数据传输以及该EDT数据传输对应的EDT接入原因,向所述终端的AS层发送第一指示信息,所述第一指示信息用于指示所述EDT数据传输和所述EDT接入原因对应的第一接入类别和第一接入标识;
2)所述终端的AS层从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集,并根据所述第一接入标识以及所述第一接入控制参数集,执行接入控制操作。
具体地,为EDT数据传输的无线接入定义至少两个新的接入类别,即每个EDT接入原因对应一个接入类别,EDT接入原因可以是mo-Data或者delayTolerantAccess等。至少两个新的接入类别和现有的MO数据传输对应的接入类别并存。UE NAS(即终端的NAS层)判断如果要执行一个EDT数据传输以及EDT接入原因,则UE NAS指示UE AS(即终端的AS层)EDT数据传输对应的第一接入类别以及第一接入标识。UE AS根据UE NAS提供的第一接入类别、第一接入标识以及从系统广播消息中获取的第一配置信息,执行接入控制操作。具体地,UE AS根据UE NAS提供的接入类别从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集,并根据所述第一接入标识以及所述第一接入控制参数集,执行接入控制操作。接入控制操作可以参照前述UAC机制的相关描述,不再赘述。
需要说明的是,第一配置信息中需要增加与第一接入类别和第一接入标识对应的接入控制参数集(即UAC-BarringInfoSet),这里的第一接入类别和第一接入标识与EDT数据传输和EDT接入原因对应。
本申请实施例中,对于上述两种方式,如果终端的NAS层提供的第一 接入类别对应的接入控制参数集没有在系统广播消息里配置,则终端不执行接入控制操作。
进一步,在本申请一些可选实施方式中,所述方法还包括:
所述终端确定数据传输类型;
若所述数据传输类型属于EDT数据传输,则所述终端根据所述EDT数据传输对应的第一接入类别从所述第一配置信息中确定与所述第一接入类别对应的第一接入控制参数集;
若所述数据传输类型属于多包数据传输,则所述终端根据所述多包数据传输对应的第二接入类别从所述第一配置信息中确定与所述第二接入类别对应的第二接入控制参数集;
其中,所述多包数据传输对应的数据包数目大于所述EDT数据传输对应的数据包数目。
举个例子:假设一个包的数据传输属于EDT数据传输,多个包的数据传输属于多包数据传输,终端确定是需要执行EDT数据传输还是需要执行多包数据传输,如果是执行EDT数据传输,则从第一配置信息中选择对应的第一接入控制参数集;如果是执行多包数据传输,则从第一配置信息中选择对应的第二接入控制参数集。
本申请实施例中,终端根据数据传输类型(即是EDT数据传输还是多包数据传输),决定向网络侧发送的第一条RRC消息(以下称为第一RRC消息)的种类,具体地,若所述数据传输类型属于EDT数据传输,则所述终端在无线接入中发送的第一RRC消息为EDT数据传输请求消息;若所述数据传输类型属于多包数据传输,则所述终端在无线接入中发送的第一RRC消息为RRC连接建立请求消息。需要说明的是,EDT数据传输请求消息也可以称为小数据传输请求消息,或小数据包传输请求消息,或小包数据传输请求消息。EDT数据传输请求消息是携带EDT数据(或称为小数 据、或小数据包、或小包数据)的上行RRC消息。

Figure PCTCN2019093393-appb-000008
方式二:所述第一信息为预配置的信息,所述第一信息指示EDT数据传输不执行接入控制操作。
这里,可以通过协议约定EDT数据传输不执行接入控制操作。
Figure PCTCN2019093393-appb-000009
方式三:所述第一信息为数据传输类型;若所述数据传输类型属于EDT数据传输,则所述终端确定不执行接入控制操作;若所述数据传输类型不属于EDT数据传输,则所述终端确定执行接入控制操作。
本申请实施例中,所述终端确定执行接入控制操作的情况下,可以参照图4中的方法来执行接入控制操作,具体地,所述终端的NAS层向所述终端的AS层发送第一指示信息,所述第一指示信息用于指示目标接入类别和目标接入标识;所述终端的AS层从第一配置信息中确定与所述目标接入类别对应的目标接入控制参数集,并根据所述目标接入标识以及所述目标接入控制参数集,执行接入控制操作。
