Abstract
本发明实施例提供了一种信息传输的方法、装置及计算机存储介质;该方法包括:基于预设的检测策略检测发生于RLC实体的事件;响应于检测到预设的辅小区无线链路失败RLF事件,通过无线资源控制RRC信令发送基于所述辅小区RLF事件所生成的上报信息。避免了UE由于RLF事件直接触发RRC重建立过程,减少了RRC重建立过程所引发的业务中断的现象。
Description
本发明实施例涉及无线通信技术领域,尤其涉及一种信息传输的方法、装置及计算机存储介质。
在第五代移动通信技术(5G,5th Generation)中,5G的无线接入技术称为New Radio,简称NR。在5G NR中,为了提升数据传输的可靠性并降低数据传输的时延,引入了数据复制(data duplication)传输机制。
目前在5G NR中,定义了载波聚合(CA,Carrier Aggregation)下的数据复制传输机制。该数据复制传输机制的技术方案利用了分组数据聚合协议(PDCP,Packet Data Convergence Protocol)层的复制数据功能。
在上述数据复制传输机制的技术方案中,每个RLC实体对应一个逻辑信道,并且每个逻辑信道可以被配置对应一个或一组小区,因此,两个逻辑信道所对应配置的小区或小区组是不同的。而对于工作在确认模式(AM,Acknowledged Mode)的RLC实体(后续简称AM RLC),如果一个数据包传输达到最大重传次数,那么就会导致RLC故障,从而触发无线链路失败(RLF,Radio Link Failure)过程。通常RLF过程会造成无线资源控制(RRC,Radio Resource Control)的重建立,而RRC重建立会大概率地引发业务中断的现象发生,因此,需要避免RLF过程所引发的业务中断现象。
发明内容
本发明实施例期望提供一种信息传输的方法、装置及计算机存储介质;能够避免RLF过程所引发的业务中断现象。
本发明实施例的技术方案可以如下实现:
第一方面,本发明实施例提供了一种信息传输的方法,所述方法包括:
基于预设的检测策略检测发生于RLC实体的事件;
响应于检测到预设的辅小区无线链路失败RLF事件,通过无线资源控制RRC信令发送基于所述辅小区RLF事件所生成的上报信息。
第二方面,本发明实施例提供了一种信息传输的方法,其中,所述方法包括:
接收承载于RRC信令中的上报信息;其中,所述上报信息基于检测到的辅小区RLF事件生成;

所述接收部分,配置为接收承载于RRC信令中的上报信息;其中,所述上报信息基于检测到的辅小区RLF事件生成;
所述确定部分,配置为基于所述上报信息确定是否进行重配置。

所述第一网络接口,用于在与其他外部网元之间进行收发信息过程中, 信号的接收和发送;
所述第一存储器,用于存储能够在所述第一处理器上运行的计算机程序;
所述第一处理器,用于在运行所述计算机程序时,执行第一方面所述信息传输方法的步骤。
第六方面,本发明实施例提供了一种网络设备,包括:第二网络接口、第二存储器和第二处理器;
其中,所述第二网络接口,用于在与其他外部网元之间进行收发信息过程中,信号的接收和发送;
所述第二存储器,用于存储能够在第二处理器上运行的计算机程序;
所述第二处理器,用于在运行所述计算机程序时,执行第二方面所述信息传输方法的步骤。
第七方面,本发明实施例提供了一种计算机存储介质,所述计算机存储介质存储有信息传输的程序,所述信息传输的程序被至少一个处理器执行时实现第一方面或第二方面所述的信息传输方法的步骤。
本发明实施例提供了一种信息传输的方法、装置及计算机存储介质;UE在检测到辅小区RLF事件后,采用RRC信令向网络侧发送上报信息,从而使得网络侧能够根据该上报信息决定是否进行重配置。避免了UE由于RLF事件直接触发RRC重建立过程,减少了RRC重建立过程所引发的业务中断的现象。

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。
对于5G NR中所定义的CA下的数据复制传输机制,相关的协议结构如图1所示,PDCP层基于协议高层接收到的PDCP服务数据单元(SDU,Service Data Unit)生成PDCP PDU后,将PDCP PDU进行复制,并且将源PDCP PDU与复制的PDCP PDU分别传输至两个RLC实体,例如图1中的RLC Entity a和RLC Entity b;随后,单一的MAC实体将不同RLC实体传输的PDCP PDU分别映射到不同的物理层载波上进行传输,例如物理载波Physical Carrier 1以及物理载波Physical Carrier 2。从而能够利用载波的频率分集增益来提高数据传输的可靠性。
基于图1所示的协议结构以及CA下的数据复制传输机制,可以得知,每个RLC实体对应一个逻辑信道,并且每个逻辑信道可以被配置对应一个或一组小区,因此,两个逻辑信道所对应配置的小区或小区组是不同的。而在目前第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)已有讨论中,对于用户设备UE的RLC实体,如果其对应的逻辑信道所配置的小区或小区组全部为辅小区,那么当AM RLC的某个RLC SDU重传达到最大重传次数时,即发生RLC故障时,可以无需触发RRC重建立,而仅需向网络侧进行上报,并由网络侧决定如何进行参数的重配置,从而减少RRC重建立造成UE的业务中断的现象发生。但是目前相关的3GPP 讨论中,并没有相关技术公开如何向网络侧进行上报的技术方案。
为了能够解决在发生RLC故障状态下,如何向网络侧进行上报的问题。本申请基于上述内容提出以下实施例。
实施例一
参见图2,其示出了本发明实施例提供的一种信息传输的方法,该方法可以应用于用户设备UE侧,所述方法包括:
S201:基于预设的检测策略检测发生于RLC实体的事件;
S202:响应于检测到预设的辅小区无线链路失败RLF事件,通过无线资源控制RRC信令发送基于所述辅小区RLF事件所生成的上报信息。
需要说明的是,所述上报信息可以用于网络侧确定是否进行重配置。
通过图2所示的技术方案,可以看出,图2所示的技术方案,UE在检测到辅小区RLF事件后,采用RRC信令向网络侧发送上报信息,从而使得网络侧能够根据该上报信息决定是否进行重配置。避免了UE由于RLF事件直接触发RRC重建立过程,减少了RRC重建立过程所引发的业务中断的现象。
针对图2所示的技术方案,在一种可能的实现方式中,所述基于预设的检测策略检测发生于RLC实体的事件,包括:
在用于PDCP复制传输的两个RLC实体中确定目标RLC实体;其中,所述目标RLC实体对应的逻辑信道所配置的小区或小区组全部为辅小区;
检测所述目标RLC实体的每一个RLC SDU或RLC PDU的重传次数。
对于上述实现方式,需要说明的是,UE在CA下进行数据复制传输的过程中,可以针对RLC实体所发生的事件进行检测,比如检测RLC实体对应的逻辑信道所配置的小区或小区组的通信质量,或者检测RLC实体对应的逻辑信道的数据传输量等;对于AM RLC实体来说,同样也可以检测AM RLC实体的某个RLC SDU或RLC PDU的重传次数等。总 之在RLC实体上所有可能发生的事件,UE都可以进行检测,而在本实施例中,针对辅小区无线链路失败RLF事件,那么UE会针对目标RLC实体的每一个RLC SDU或RLC PDU的重传次数更加感兴趣,因此,具体可以针对目标RLC实体的每一个RLC SDU或RLC PDU的重传次数进行检测。基于上述实现方式,相应来说,当重传次数达到预设的重传次数阈值时,UE就能够认定检测到辅小区无线链路失败RLF事件,该阈值可以认为是针对RLC SDU或RLC PDU进行重传能够容忍的最大次数。因此,所述检测到预设的辅小区无线链路失败RLF事件,包括:
当所述目标RLC实体的任一RLC SDU或RLC PDU的重传次数达到预设的最大重传次数,确定检测到所述辅小区RLF事件。
可以理解地,当检测到所述辅小区RLF事件后,为了避免UE直接发起RRC重建立过程而导致业务中断的现象发生,通常会采用向网络侧进行上报,并且网络侧根据上报确定是否进行RRC重配置。
基于上述理解性内容,对于图2所示的技术方案,在一种可能的实现方式中,所述响应于检测到预设的辅小区无线链路失败RLF事件,通过无线资源控制RRC信令发送基于所述辅小区RLF事件所生成的上报信息,包括:
当检测到所述辅小区RLF事件时,触发通过RRC信令发送第一上报信息,其中,所述第一上报信息基于所述检测到的辅小区RLF事件生成。
对于上述实现方式,需要说明的是,辅小区RLF事件可以作为发送第一上报信息的触发条件,并且当第一上报信息发送之后,是否针对辅小区RLF事件进行RRC重配置是由网络侧进行决定。基于此,本实施例可以预先设置定时器来使得UE及时获知网络侧是否决定进行RRC重配置。因此,针对上述实现方式,所述触发通过RRC信令发送第一上报信息,包括:
若预设的定时器处于非计时状态,触发通过RRC信令发送所述第一上 报信息,并启动所述定时器。
在定时器计时过程中,UE侧可能还会出现多种情况,因此,针对计时过程中所可能额外出现的情况,本实施例采用了以下优选方案进行处理。
优选地,在所述定时器计时过程中,不触发通过RRC信令发送所述第一上报信息,并将所述再次检测到的辅小区RLF事件设置为等待状态。
针对上述优选方案,还可以包括:
当所述定时器超时时,若存在处于等待状态的辅小区RLF事件,通过无线资源控制RRC信令发送第二上报信息,其中,所述第二上报信息基于待定状态的辅小区RLF事件生成。
可以理解地,在定时器计时过程中,可能还会继续检测到辅小区RLF事件,但是此时网络侧并没有进行RRC重配置的指示,因此,为了降低网络侧的处理负荷,在定时器计时过程中所检测到的所有辅小区RLF事件,可以在定时器超时后统一向网络侧上报。
优选地,在所述定时器计时过程中,若接收到RRC重配置信令,停止所述定时器。
可以理解地,在定时器计时过程中,若接收到网络侧基于第一上报信息反馈的RRC重配置信令,那么就针对目标RLC实体对应的逻辑信道进行RRC重配置过程,因此,定时器计时停止,定时器转为非定时状态,从而在RRC重配置过程完成之后,重新依照S201检测发生于RLC实体的事件。
需要说明的是,RRC重配置信令停止定时器计时,是考虑到RRC重配置已经对辅小区RLF事件进行了处理。基于此,在定时器停止计时后,上述优选示例还可以包括:将定时器在停止计时前的计时过程中所有设置的等待状态的辅小区RLF事件进行取消,从而无需再向网络侧上报针对等待状态的辅小区RLF事件生成的第二上报信息,网络侧也相应地无需根据 第二上报信息再确定是否进行RRC重配置。
此外,针对接收到的RRC重配置信令,具体可以是包含有特定内容的重配置信令。所述特定内容指的是包含有对辅小区RLF进行处理的重配置信令,例如是包含有重配置RLC实体的相关信令。只有是包含有特定内容的重配置信令才会停止计时器,否则不会对计时器产生影响。
前述两种可能的实现方式详细阐述了图2所示方案的具体实现过程,但是,由于网络侧基于上报信息来确定是否进行重配置,因此,承载于RRC信令中的上报信息就需要能够使网络测获知与辅小区RLF事件相关的描述信息。因此,基于上述内容,在一种可能的实现方式中,所述上报信息包括所述辅小区RLF事件的描述信息。
对于该实现方式,具体来说,所述上报信息包括:所述目标RLC实体具有关联关系的标识信息和/或所述目标RLC实体对应的小区质量信息。
以所述目标RLC实体具有关联关系的标识信息来说,具体可以包括:所述目标RLC实体所在的逻辑信道标识、小区组标识、承载标识以及所述目标RLC实体对应的小区标识中的至少一项。
以所述目标RLC实体对应的小区质量信息来说,具体包括以下至少一项:
在所述目标RLC实体对应的小区所属频率上的当前服务小区的质量信息以及质量最好的非服务小区的质量信息;
除所述目标RLC实体对应的小区之外其他服务小区的所属频率上的当前服务小区的质量信息和质量最好的非服务小区质量信息;
除所有服务小区的所属频率之外其他频率上的质量最好的小区。
需要说明的是,在上述实现方式中,所述目标RLC实体对应的小区包括:所述目标RLC实体对应的激活小区,或者,所述目标RLC实体对应的激活小区和非激活小区。
可以理解地,前述上报信息的实现方式,能够从多方面描述辅小区RLF事件,因此,网络侧就能够依据上报信息准确的确定是否进行重配置。
本实施例提供了一种信息传输的方法,UE在检测到辅小区RLF事件后,采用RRC信令向网络侧发送上报信息,从而使得网络侧能够根据该上报信息决定是否进行重配置。避免了UE由于RLF事件直接触发RRC重建立过程,减少了RRC重建立过程所引发的业务中断的现象。

具体来说,结合前述实施例所述的上报信息中可能包含的内容,网络侧设备可以基于上报信息中可能包含的内容针对重配置进行决策,从而确定是否进行重配置。
本实施例提供了一种信息传输的方法,网络侧接收到在基于辅小区RLF事件生成的上报信息后,基于上报信息确定是否进行重配置。避免了UE由于RLF事件直接触发RRC重建立过程,减少了RRC重建立过程所引发的业务中断的现象。
