Description

一种接入控制的方法、设备及计算机可读介质 技术领域
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。
背景技术
在长期演进(LTE,Long Term Evolution)系统中,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系统设计复杂度的提升,需要设计及实现一种统一的接入控制(UAC,Unified Access Control)机制;此外,由于5G系统中引入了按需请求的机制,也就是说终端在向网络侧发送按需的系统信息请求时,可以基于RACH信令、MSG3消息以及如MSG5的RRC专用信令进行发送。
由于采用了UAC机制,能够解决5G系统可能出现的拥塞问题,但是目前的方案中,在拥塞状态下,当按需的系统信息请求由于接入控制AC被推迟,且终端无法在规定时延内接收到针对按需的系统信息请求的回复时,会造成终端产生网络侧不具有提供系统信息能力的误解,从而影响了终端的业务支持和业务体验。
发明内容
为解决上述技术问题,本发明实施例期望提供一种接入控制的方法、设备及计算机可读介质;能够降低按需的系统信息请求被拒绝接入的概率,并且避免终端误解网络侧设备不具有提供系统信息能力

第二方面,本发明实施例提供了一种接入控制的方法,所述方法应用于终端,所述方法包括:
发送按需的系统信息请求;

具体实施方式
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。
终端所发送的按需的系统信息请求被拒绝接入后,通常终端会认为网络侧设备不具有提供相应系统信息的能力。但是按照目前相关技术,如果按需的系统信息请求因为网络侧设备进行接入控制被拒绝后,终端依然会认为网络侧设备不具有提供相应系统信息的能力,从而造成了终端对网络侧设备的能力产生误解。因此,目前不仅需要提高按需的系统信息请求在 接入控制中的接入成功概率,而且还需要在拒绝接入时告知终端拒绝接入的原因,避免终端对网络侧设备的能力产生误解。基于以上内容,以下通过多个非典型实施例对本发明实施例的技术方案进行阐述。
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,所述方法应用于网络侧设备,所述方法包括:
S101:接收终端发送的按需的系统信息请求;
S102:基于设定的优先策略针对所述按需的系统信息请求进行接入控制;
S103:当接入控制的结果为拒绝接入时,向所述终端发送针对所述按需的系统信息请求的第一回复指示信息;其中,所述第一回复指示信息用于指示所述按需的系统信息请求由于接入控制被拒绝。
本实施例中,网络侧设备非典型性地可以优选为5G基站gNB。通过图1所示的技术方案,网络侧设备一方面提高按需的系统信息请求进行接入控制时的优先级,从而降低按需的系统信息请求被拒绝接入的概率,另一方面将拒绝接入的原因向终端回复,从而能够使得终端获知被拒绝接入的原因是接入控制AC而并非其他原因,避免了终端误解网络侧设备不具有提供系统信息能力。
对于图1所示的技术方案,在一种可能的实现方式中,当接入控制的结果为允许接入时,所述方法还包括:
向所述终端发送针对所述按需的系统信息请求的第二回复指示信息;其中,所述第二回复指示信息用于指示所述按需的系统信息请求被允许接入。
需要说明的是,终端可以根据第二回复指示信息获知接入控制的结果为允许接入,从而终端就可以和网络侧设备完成接入的后续过程,本 实施例对此不做赘述。
对于图1所示的技术方案,在一种可能的实现方式中,终端可以在空闲态idle或非激活态inactive发送按需的系统信息请求,也可以在连接态connected发送按需的系统信息请求,基于此,所述接收终端发送的按需的系统信息请求,包括:
接收处于空闲态idle或非激活态inactive的终端发送的一号消息MSG1;其中,所述MSG1中携带有所述按需的系统信息请求;
或者,接收处于空闲态idle或非激活态inactive的终端发送的三号消息MSG3;其中,所述MSG3中携带有所述按需的系统信息请求;
或者,接受处于连接态connected的终端发送的第一RRC专用信令;其中,所述第一RRC专用信令中携带有所述按需的系统信息请求。
具体来说,MSG1可以是终端在物理随机接入信道(PRACH,Physical Random Access Channel)上发送的随机接入Random Access前导preamble。MSG3可以是终端发送的无线资源控制(RRC,Radio Resource Control)建立请求或重建请求;第一RRC专用信令可以优选为MSG5,比如可以是终端回复的RRC建立或重建完成消息。
相应地,当所述MSG1中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于二号消息MSG2;具体来说,MSG2可以是针对MSG1回复的ACK;
当所述MSG3中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于四号消息MSG4;具体来说,MSG4可以是RRC建立或重建命令;
当所述第一RRC专用信令中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于第二RRC专用信令;具体来说,第二RRC专用信令可以优选为在终端回复RRC建立或重建完成消息之后,其他关 于RRC的专用信令。
对于图1所示的技术方案,在一种可能的实现方式中,基于设定的优先策略针对所述按需的系统信息请求进行接入控制,包括:
针对所述按需的系统信息请求不进行接入控制;
或者,提高所述按需的系统信息请求的优先级,根据提高优先级后的按需的系统信息请求进行接入控制。
可以理解地,当针对所述按需的系统信息请求不进行接入控制,那么网络侧设备就不会由于接入控制而拒绝按需的系统信息请求;此时,网络侧设备拒绝按需的系统信息请求的理由就是网络侧设备不具有提供系统信息能力。由此可知,如果终端没有收到针对按需的系统信息请求的回复消息,那么终端就可以直接认为网络侧设备不具有提供系统信息能力,从而避免产生误解。
另外,当提高所述按需的系统信息请求的优先级,根据提高优先级后的按需的系统信息请求进行接入控制时,能够提升按需的系统信息请求的接入概率,降低拒绝接入的发生概率;可以一旦出现拒绝接入,那么终端也可以通过第一回复指示信息知晓拒绝接入的原因为接入控制,从而不会产生网络侧设备不具有提供系统信息能力的误解。终端就能够按照第一回复指示信息确定是否继续向网络侧设备发送所述按需的系统信息请求。
基于上述实现方式,优选地,当所述按需的系统信息请求承载于处于空闲态idle或非激活态inactive的终端发送的一号消息MSG1中时,所述提高所述按需的系统信息请求的优先级,包括:
针对所述按需的系统信息请求配置对应的随机接入回退参数RACH backoff参数和回退时间backoff timer。
可以理解地,随机接入回退参数RACH backoff参数和回退时间backoff  timer指的是UE在随机接入失败后,从0与RACH backoff参数之间按照平均分布随机选择一个backoff timer值。之后,UE按照选择的backoff timer值延迟下一次随机接入的发送。因此,通过RACH backoff参数值和回退时间backoff timer值就能够反应随机接入的优先级,因此,网络侧设备针对所述按需的系统信息请求配置对应的随机接入回退参数RACH backoff参数和回退时间backoff timer后,就可以提升接入概率,降低接入响应时延。也就是所述按需的系统信息请求的优先级。
基于上述实现方式,优选地,当所述按需的系统信息请求承载于处于空闲态idle或非激活态inactive的终端发送的三号消息MSG3中,或者所述按需的系统信息请求承载于处于连接态connected的终端发送的第一RRC专用信令中时,所述提高所述按需的系统信息请求的优先级,包括:
针对所述按需的系统信息请求配置设定的接入控制AC参数;其中,所述设定的接入控制AC参数能够降低接入控制时的拒绝概率。
可以理解地,设定的接入控制AC参数不同于其他MSG3或MSG5的AC参数,相比于其他MSG3或MSG5的AC参数,上述设定的接入控制AC参数能够降低接入控制时的拒绝概率。
通过以上方案,一方面提高按需的系统信息请求进行接入控制时的优先级,从而降低按需的系统信息请求被拒绝接入的概率,另一方面将拒绝接入的原因向终端回复,从而能够使得终端获知被拒绝接入的原因是接入控制AC而并非其他原因,避免终端误解网络侧设备不具有提供系统信息能力。
实施例二
基于前述实施例相同的发明构思,参见图2,其示出了本发明实施例提供的一种接入控制的方法,所述方法应用于终端,所述方法包括:
S201:发送按需的系统信息请求;
S202:接收针对所述按需的系统信息请求的第一回复指示信息;其中,所述第一回复指示信息用于指示所述按需的系统信息请求由于接入控制被拒绝。
对于图2所示的技术方案,在一种可能的实现方式中,所述发送按需的系统信息请求,包括:
当所述终端处于空闲态idle或非激活态inactive时,发送一号消息MSG1或三号消息MSG3;其中,所述MSG1或所述MSG3中携带有所述按需的系统信息请求;
当所述终端处于连接态connected时,发送第一RRC专用信令;其中,所述第一RRC专用信令中携带有所述按需的系统信息请求。第一RRC专用信令可以优选为MSG5,比如可以是终端回复的RRC建立或重建完成消息
在上述实现方式中,当所述MSG1中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于二号消息MSG2;
当所述MSG3中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于四号消息MSG4;
当所述第一RRC专用信令中携带有所述按需的系统信息请求时,所述第一回复指示信息承载于第二RRC专用信令。具体来说,第二RRC专用信令可以优选为在终端回复RRC建立或重建完成消息之后,其他关于RRC的专用信令。
可以理解地,当终端通过第一回复指示信息获知按需的系统信息请求由于接入控制被拒绝时,终端就不会对网络侧设备提供系统信息的能力产生误解,终端就能够按照第一回复指示信息确定是否继续向网络侧设备发送所述按需的系统信息请求。
通过上述方案,能够使得终端获知被拒绝接入的原因是接入控制AC 而并非其他原因,避免了终端误解网络侧设备不具有提供系统信息能力。
实施例三
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具体流程,在该流程中,终端可以是用户设备(UE,User Equipment);网络侧设备可以优选为gNB,该流程可以包括:
S301:终端向gNB发送按需的系统信息请求;
S302:gNB基于设定的优先策略针对所述按需的系统信息请求进行接入控制;
S303:gNB针对所述按需的系统信息请求向终端发送回复消息。
针对图3所示的技术方案,回复消息可以包括两种类型中的任一项:用于指示所述按需的系统信息请求由于接入控制被拒绝的第一回复指示信息、用于指示所述按需的系统信息请求被允许接入的第二回复指示信息。
可以理解地,终端接收到第一回复指示信息后,可以通过第一回复指示信息知晓拒绝接入的原因为接入控制,从而不会产生网络侧设备不具有提供系统信息能力的误解。终端就能够按照第一回复指示信息确定是否继续向网络侧设备发送所述按需的系统信息请求。
针对图3所示的技术方案,对于步骤S301来说,当所述终端处于空闲态idle或非激活态inactive时,发送一号消息MSG1或三号消息MSG3;其中,所述MSG1或所述MSG3中携带有所述按需的系统信息请求;
当所述终端处于连接态connected时,发送第一RRC专用信令;其中,所述第一RRC专用信令中携带有所述按需的系统信息请求。第一RRC专用信令可以优选为MSG5,比如可以是终端回复的RRC建立或重建完成消息
相应来说,对于步骤S303:当所述MSG1中携带有所述按需的系统信息请求时,所述回复消息承载于二号消息MSG2;
当所述MSG3中携带有所述按需的系统信息请求时,所述回复消息承载于四号消息MSG4;
当所述第一RRC专用信令中携带有所述按需的系统信息请求时,所述回复消息承载于第二RRC专用信令。具体来说,第二RRC专用信令可以优选为在终端回复RRC建立或重建完成消息之后,其他关于RRC的专用信令。
针对图3所示的技术方案,对于步骤S302来说,优选地,gNB可以针对所述按需的系统信息请求不进行接入控制;
需要说明的是,当针对所述按需的系统信息请求不进行接入控制,那么网络侧设备就不会由于接入控制而拒绝按需的系统信息请求;此时,网络侧设备拒绝按需的系统信息请求的理由就是网络侧设备不具有提供系统信息能力。由此可知,如果终端没有收到针对按需的系统信息请求的回复消息,那么终端就可以直接认为网络侧设备不具有提供系统信息能力,从而避免产生误解。
对于步骤S302来说,优选地,gNB提高所述按需的系统信息请求的优先级,根据提高优先级后的按需的系统信息请求进行接入控制。
需要说明的是,当提高所述按需的系统信息请求的优先级,根据提高优先级后的按需的系统信息请求进行接入控制时,能够提升按需的系统信息请求的接入概率,降低拒绝接入的发生概率;可以一旦出现拒绝接入,那么终端也可以通过第一回复指示信息知晓拒绝接入的原因为接入控制,从而不会产生网络侧设备不具有提供系统信息能力的误解。
可以理解地,gNB提高所述按需的系统信息请求的优先级的具体实现过程可以参见实施例一中的相应优选示例,本实施例对此不做赘述。
通过以上方案,一方面提高按需的系统信息请求进行接入控制时的优先级,从而降低按需的系统信息请求被拒绝接入的概率,另一方面将拒绝 接入的原因向终端回复,从而能够使得终端获知被拒绝接入的原因是接入控制AC而并非其他原因,避免了终端误解网络侧设备不具有提供系统信息能力。
