- the UE in the connected state or the inactive state generates a first cause value for performing AC by using the RRC layer, and is encapsulated and sent in the RRC dedicated signaling to the network side device. Therefore, when the second layer value is not provided by the NAS layer of the UE, the network side device is still enabled to perform AC control according to the first cause value generated by the RRC layer.
- the UE may generate the first cause value through the RRC layer regardless of whether the NAS layer of the UE provides the second cause value in the RRC dedicated signaling to be sent, and is encapsulated in the Send RRC dedicated signaling.

- the coordination process between the NAS and RRC layers caused by filling both the first cause value and the second cause value in the same IE is avoided.
- the IEs where the first cause value and the second cause value are independent of each other if the second cause value has a higher priority than the first cause value, then In the RRC dedicated signaling, the additionally set IE may be set to be provided by the non-access stratum NAS.

Description
本发明实施例涉及无线通信技术领域,尤其涉及一种接入控制的方法,设备及计算机可读介质和***。
在长期演进(LTE,Long Term Evolution)***中,为了避免网络过载现象的发生,引入了接入控制准入(ACB,Access Control Barring)机制,此外,还引入了数据通信中应用相关的拥塞控制(ACDC,Application specific Congestion Control for Data Communication)、扩展的接入准入(EAB,Extended Access Barring)以及业务相关的接入控制(SSAC,Service-specific Access Control)等多种接入控制机制。
而随着通信技术的发展,第五代移动通信技术(5G,5th Generation)的研究也已经展开。5G的无线接入叫New Radio,简称NR。在5G NR中,为了避免不同接入控制机制所导致的***设计复杂度的提升,需要设计及实现一种统一的接入控制(UAC,Unified Access Control)机制。而在LTE***中,接入控制AC机制的执行通常基于非接入层(NAS,Non-Access Stratum)消息中所提供的原因值cause value,将该NAS消息映射到相应接入类别access category中,此外,每个接入类别有不同的阻拦barring参数,从而实现以不同的概率进行barring处理,并维持不同的阻拦barring时间。
从上述LTE***下的AC机制可以看出,目前相关技术中的AC机制均需要NAS层提供cause value;而在5G***中,用户设备(UE,User Equipment)可以处于连接Connected态或非激活inactive态。当UE处于Connected态时,UE连接到接入网与核心网;UE处于inactive态时,UE
连接到接入网,但未连接到核心网。此时,UE的接入不会通过NAS层触发,也就无法由NAS层提供原因值cause value。综上所述,目前相关技术中,无法对非NAS层触发的接入进行接入控制。

为了能够更加详尽地了解本发明实施例的特点与技术内容,下面结合附图对本发明实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本发明实施例。
实施例一
参见图1,其示出了本发明实施例提供的一种接入控制的方法,该方法可以应用于用户设备(UE,User Equipment),该方法可以包括:
S101:通过无线资源控制(RRC,Radio Resource Control)层生成第一原因值cause value;
S102:将所述第一原因值封装于待发送RRC专用信令中;
S103:将封装有所述第一原因值的待发送RRC专用信令发送至网络侧设备;其中,所述待发送RRC专用信令用于所述网络侧设备进行接入控制。
可以理解地,处于connected态或inactive态的UE,通过RRC层生成用于进行AC的第一原因值,并封装在RRC专用信令中向网络侧设备发送,
从而在UE的NAS层没有提供第二原因值时,仍然使得网络侧设备能够根据RRC层所生成的第一原因值进行AC控制。
需要说明的是,对于图1所示的技术方案,无论UE的NAS层是否在待发送RRC专用信令中提供第二原因值,UE都可以通过RRC层生成第一原因值,并封装在待发送RRC专用信令中。也就是说,在待发送RRC专用信令中,第二原因值的优先级可以高于第一原因值,即当网络侧设备在接收到待发送RRC专用指令后,可以优先根据第二原因值进行接入控制AC;如果待发送RRC专用信令中不存在第二原因值时,才会根据第一原因值进行接入控制AC。
对于上述说明,待发送RRC专用信令中可以同时承载有第一原因值和第二原因值,但同时承载两个原因值会增加信令传输过程中的资源开销。基于此,UE可以在NAS层无法提供第二原因值的情况下通过RRC层提供第一原因值。但是,UE可以通过多种方式来确定NAS层无法提供第二原因值的情况,因此,本实施例通过以下两种可选示例进行说明。
可选示例一,所述通过无线资源控制RRC层生成第一原因值cause value之前,还可以包括:
检测所述待发送RRC专用信令中是否存在非接入层NAS提供的第二原因值;
当所述待发送RRC专用信令中不存在所述第二原因值时,通过RRC层生成所述第一原因值。
可以理解地,UE可以直接对待发送RRC专用信令进行检测;如果待发送RRC专用信令并非NAS层触发,或者NAS层无法在待发送RRC信令中提供第二原因值,那么,待发送RRC专用信令中就不会存在第二原因值。所以,当待发送RRC专用信令中不存在所述第二原因值时,就说明网络侧设备需要通过第一原因值进行AC控制。
可选示例二,所述通过无线资源控制RRC层生成第一原因值cause
value之前,所述方法还包括:
检测所述UE所处的RRC状态;
当所述UE处于连接Connected态或非激活inactive态时,通过无线资源控制RRC层生成第一原因值cause value。
可以理解地,当UE处于连接Connected态或非激活inactive态时,由于UE至少连接到接入网,因此,UE处于Connected态或inactive态时,也不会由NAS层触发RRC消息。所以上述两个状态下,NAS层同样无法提供第二原因值,就说明网络侧设备需要通过第一原因值进行AC控制。
对于图1所示的技术方案,在一种可能的实现方式中,为了避免与第二原因值所在的值域发生冲突,优选地,所述将所述第一原因值封装于待发送RRC专用信令中,包括:
在所述待发送RRC专用信令中额外设置信息单元(IE,Information Element);
将所述第一原因值填入所述额外设置的IE中。
对于本实现方式,参见图2,其示出了本发明实施例提供的一种RRC专用信令的IE示意图,可以看出,原先的RRC专用信令中,参见无填充框所示,除了其他RRC信息单元IE之外,还包括一个IE,该IE中的内容是由NAS层填写的原因值,也就是第二原因值;而本实施例额外增加了一个IE,如图2中斜线填充框所示,该额外增加的IE中的内容则是由RRC层填写的原因值,也就是第一原因值。
可以理解地,UE可以在待发送RRC专用信令通过额外设置IE来填充第一原因值,从而区分NAS层提供的第二原因值。避免了将第一原因值和第二原因值均填充在同一IE中所导致的NAS与RRC层之间的协调过程。
优选地,在图2中,第一原因值和第二原因值所在的IE是相互独立的,但是,基于前述说明,若第二原因值的优先级高于第一原因值,那么在待发送RRC专用信令中,所述额外设置的IE可以设置在非接入层NAS提供
的第二原因值所在的IE之后。这样就可以使得网络侧设备在对所述待发送RRC专用信令进行解析的过程中,首先检测第二原因值,随后再根据第二原因值存在与否来确定是否检测第一原因值来进行AC。
本实施例提供的一种接入控制的方法,终端可以在待发送的RRC专用信令中封装由RRC层生成的第一原因值,使得网络侧设备在接收到待发送RRC专用信令后,即使无法获得NAS层提供的第二原因值,仍然能够基于UE的RRC层所提供的第一原因值进行接入控制,从而能够对非NAS层触发的接入进行接入控制。
实施例二
基于前述实施例相同的发明构思,参见图3,其示出了本发明实施例提供的一种接入控制的方法,该方法可以应用于网络侧设备,具体可以是5G基站gNB或者核心访问与移动性管理(AMF,Core Access and Mobility Management Function);该方法可以包括:
S301:接收用户设备UE发送的RRC专用信令;
S302:解析所述RRC专用信令,获得所述RRC专用信令中承载的第一原因值;其中,所述第一原因值由所述UE通过无线资源控制RRC层生成;
S303:根据所述第一原因值查询针对所述RRC专用信令的接入类别Access Category;
S304:根据所述接入类别对所述RRC专用信令进行接入控制AC。
可以理解地,本实施例中,网络侧设备根据RRC专用信令中的第一原因值进行接入控制AC,从而能够使得网络侧设备可以针对非NAS层触发的RRC专用信令或在RRC专用信令中无法提供原因值的情况下进行接入控制AC。
对于图3所示的技术方案,在一种可能的实现方式中,解析所述RRC专用信令,获得所述RRC专用信令中承载的第一原因值,可以包括:
解析所述RRC专用信令,查找所述RRC专用信令是否存在非接入层NAS提供的第二原因值;
当所述RRC专用信令中不存在所述第二原因值时,查找是否存在RRC层生成的第一原因值;
当所述RRC专用信令中存在所述第一原因值时,获取所述第一原因值。
通常来说,当RRC专用信令中存在由UE的NAS层所提供的第二原因值时,网络侧设备就会获取第二原因值对应的接入类别Access Category,随后网络侧设备的RRC协议层就可以根据第二原因值对应的接入类别进行接入控制。因此,可以看出,第二原因值的优先级可以高于第一原因值的优先级。所以,在本实施例中,首先会检测是否存在第二原因值;如果存在,则根据第二原因值对应的接入类别进行接入控制;如果不存在,则继续检测是否存在第一原因值,若存在第一原因值,则可以根据第一原因值对应的接入类别进行接入控制。
基于实施例一的技术方案,可以得知,为了避免将第一原因值和第二原因值均填充在同一IE中所导致的NAS与RRC层之间的协调过程,UE会通过额外设置IE来填充第一原因值,从而区分NAS层提供的第二原因值。第一原因值和第二原因值所在的IE是相互独立的。基于此,在上述实现方式中,查找是否存在RRC层生成的第一原因值,具体可以包括:
查找是否存在额外设置的信息单元IE;
当查找到所述额外设置的IE,检测所述额外设置的IE中是否存在所述第一原因值。
进一步地,为了能够顺序地对RRC专用信令进行检测,优选地,所述第一原因值所在的IE设置在所述第二原因值所在的IE之后。
本实施例提供的一种接入控制的方法,网络侧设备在接收到待发送RRC专用信令后,即使无法获得NAS层提供的第二原因值,仍然能够基于UE的RRC层所提供的第一原因值进行接入控制,从而能够对非NAS层触
发的接入进行接入控制。
实施例三
基于前述实施例相同的发明构思,参见图4、其示出了本发明实施例提供的一种接入控制的具体流程,该具体流程非典型地适用于非NAS层触发的RRC信令或NAS层无法在RRC信令中提供原因值的情况,该具体流程可以包括:
S401:UE通过RRC层生成第一原因值;
S402:UE在待发送RRC专用信令中额外设置一个IE;
S403:UE将第一原因值填入该额外设置的IE后,向网络侧设备发送该待发送RRC专用信令;
需要说明的是,无论UE的NAS层是否在待发送RRC专用信令中提供第二原因值,UE都可以通过RRC层生成第一原因值。可以理解地,若UE的NAS层能够在待发送RRC专用信令中提供第二原因值,那么可以说明该待发送RRC专用信令由UE的NAS层触发。通常来说,跟踪区更新(TAU,Tracking Area Update)消息,服务请求service request消息等RRC专用信令均是由NAS层触发;而非NAS层触发的RRC信令或NAS层无法提供原因值的RRC信令通常可以是请求按需***信息的消息、也可以是请求副链路UE信息sidelinkUEInformation等消息。
可以理解地,当UE将承载有第一原因值的待发送RRC专用信令发送至网络侧设备后,网络侧设备就可以根据待发送RRC专用信令中的原因值(无论是第一原因值还是第二原因值)进行接入控制AC。
S404:网络侧设备检测RRC专用信令中是否存在NAS层提供的第二原因值;
若是,则转至S405:获取第二原因值对应的接入类别Access Category,并根据第二原因值对应的接入类别进行接入控制;
否则,转至S406:检测是否存在RRC层提供的第一原因值;
若是,则转至S407:获取第一原因值对应的接入类别,并根据第一原因值对应的接入类别进行接入控制
否则,转至S408:针对待发送RRC专用信令不进行接入控制AC。
可以理解地,不同的接入类别对应不同的阻拦barring参数,从而实现以不同的概率进行barring处理,并维持不同的阻拦barring时间。
通过图4所示的技术方案,可以看出,在NAS层无法提供原因值的情况下,网络侧设备可以UE的RRC层提供的第一原因值进行接入控制,从而能够对非NAS层触发的接入进行接入控制。
