Description

一种悬挂RRC连接的方法及装置、计算机存储介质 技术领域
本发明涉及无线通信技术领域,尤其涉及一种悬挂无线资源控制(RRC,Radio Resource Control)连接的方法及装置、计算机存储介质。
背景技术
为了满足人们对业务的速率、延迟、高速移动性、能效的追求,以及未来生活中业务的多样性、复杂性,第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)国际标准组织开始研发第五代(5G,5 th Generation)移动通信技术。
5G移动通信技术的主要应用场景为:增强型移动宽带(eMBB,Enhance Mobile Broadband)、低时延高可靠通信(URLLC,Ultra Reliable Low Latency Communication)、大规模机器类通信(mMTC,massive Machine Type Communication)。
在5G网络环境中,为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义一个新的RRC状态,即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC连接(RRC_CONNECTED)状态。
当用户设备(UE,User Equipment)处于RRC_INACTIVE状态时,网络侧会通过专用信令给UE配置无线接入网(RAN,Radio Access Network)的寻呼区域,该RAN寻呼区域可以是一个小区或者多个小区。当UE在该区域内移动时不用通知网络侧,遵循空闲(idle)下移动性行为,即小区选择重选原则。当UE移动出RAN配置的寻呼区域时,会触发UE恢复RRC连接并重新获取RAN配置的寻呼区域。当UE有下行数据到达时,为UE保持RAN和核心网(CN,Core Network)之间连接的基站(如gNB)会触发RAN寻呼区域内的所有小区发送寻呼消息给UE,使得INACTIVCE状态的UE能够恢复RRC连接,进行数据接收。
所以UE从INACTIVE状态进入RRC连接状态,有三种情况:
一是,UE有下行数据到达,网络侧发起RAN侧的寻呼,促使UE进入连接状态;
二是,UE自身发起RAN位置区域更新,例如周期性RAN位置更新或者跨区域位置更新;
三是,UE有上行数据发送需求,促使UE进入连接状态。
为了支持更高的业务速率需求,网络侧支持双连接(DC,Dual Connectivity)或者多连接(MC,Multiple Connectivity)。但是对于DC/MC连接方式的UE,如何支持INACTIVE状态是需要解决的问题。

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。
本发明实施例的技术方案主要应用于5G移动通信系统,当然,本发明实施例的技术方案并不局限于5G移动通信系统,还可以应用于其他类型的移动通信系统。以下对5G移动通信系统中的主要应用场景进行说明:
1)eMBB场景:eMBB以用户获得多媒体内容、服务和数据为目标,其业务需求增长十分迅速。由于eMBB可能部署在不同的场景中,例如室内、市区、农村等,其业务能力和需求的差别也比较大,所以必须结合具体的部署场景对业务进行分析。
2)URLLC场景:URLLC的典型应用包括:工业自动化、电力自动化、远程医疗操作、交通安全保障等。
3)mMTC场景:URLLC的典型特点包括:高连接密度、小数据量、时延不敏感业务、模块的低成本和长使用寿命等。
以下对5G网络环境中的三种RRC状态进行说明:
1)RRC_IDLE状态:移动性为基于UE的小区选择重选,寻呼由CN发起,寻呼区域由CN配置。基站侧不存在UE AS上下文。不存在RRC连接。
2)RRC_CONNECTED状态:存在RRC连接,基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
3)RRC_INACTIVE状态:移动性为基于UE的小区选择重选,存在CN和RAN之间的连接,UE AS上下文存在某个基站上,寻呼由RAN触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。
图1为RRC连接恢复过程的示意图,如图1所示,RRC连接恢复过程包括以下流程:
步骤101:UE处于INACTIVE状态,要恢复RRC连接。
步骤102:UE向gNB发送前导码(preamble)。
步骤103:gNB向UE发送随机接入响应(RAR,Random Access Response)。
步骤104:UE向gNB发送RRC恢复请求消息(RRC Connection Resume Request)。
步骤105:gNB向锚gNB(anchor gNB)索要UE上下文信息。
步骤106:gNB向UE发送RRC连接恢复消息(RRC Connection Resume)。
步骤107:UE进入RRC连接(RRC_CONNECTED)状态。
步骤108:UE向gNB发送RRC连接恢复完成消息(RRC Connection Resume Complete)。
本发明实施例的技术方案,定义了完全RRC连接悬挂以及部分RRC连接悬挂两个新概念,并使得网络侧和UE侧可以支持INACTIVE状态。值得说明的是,完全RRC连接悬挂是指悬挂全部RRC连接,部分RRC连接悬挂是指悬挂部分RRC连接,进一步,所述悬挂部分RRC连接是指悬挂SCG部分的资源。
图2为本发明实施例的悬挂RRC连接的方法的流程示意图一,如图2所示,所述悬挂RRC连接的方法包括以下步骤:
步骤201:如果第一节点确定所述第一节点侧的业务处于第一状态,则所述第一节点确定需要悬挂RRC连接。
本发明实施例中,所述第一节点为双连接(DC)网络或者多连接(MC)网络中的主节点(MN),所述第二节点为双连接网络或者多连接网络中的辅节点(SN)。本发明实施例中是MN初始的RRC连接悬挂过程,具体地,MN侧检测出业务处于第一状态下,触发的RRC连接悬挂过程。这里,业务的第一状态是指业务处于非活跃状态,相对于第一状态而言,还具有一个状态称为第二状态,也即活跃状态。应理解,本发明以下实施例中提及到的业务未处于第一状态,是指业务处于活跃状态。
本发明实施例中,所述第一节点可以通过以下方式确定所述第一节点侧的业务处于第一状态:
方式一:如果所述第一节点连续接收到N个所述第一节点侧的业务承载对应的缓冲区大小等于0(即BSR=0)的缓冲区状态报告,则确定所述第一节点侧的业务处于第一状态,N为正整数。
例如:MN侧连续收到N个MN侧业务承载对应的BSR=0的上报,则MN判决悬挂RRC连接,然后,通知SN并与SN协商该判决。
方式二:所述第一节点接收到所述第一节点侧的业务承载对应的首个缓冲区大小等于0的缓冲区状态报告时,启动第一定时器;如果在所述第一定时器运行期间,所述第一节点接收到所述第一节点侧的业务承载对应的缓冲区大小不等于0的缓冲区状态报告,则停止所述第一定时器;其中,如果在触发停止所述第一定时器之前,所述第一定时器超时,则确定所述第一节点侧的业务处于第一状态。
例如:MN侧收获到MN侧业务承载对应的第一个BSR=0的上报,启动定时器timer1,重新收到MN侧业务承载对应的BSR≠0的上报,则停止定时器timer1。如果该定时器timer1超时,则MN判决悬挂RRC连接并通知SN并与SN协商该判决。
步骤202:所述第一节点向第二节点发送第一通知消息,并与所述第二节点协商是否需要悬挂RRC连接,其中,所述第一通知消息用于向所述第二节点通知所述第一节点确定出需要悬挂RRC连接。
本发明实施例中,所述与所述第二节点协商是否需要悬挂RRC连接,具体包括:
1)如果所述第二节点侧的业务未处于第一状态,则所述第一节点接收所述第二节点发送的第二通知消息,所述第二通知消息用于向所述第一节点通知不能悬挂RRC连接。
例如:如果SN侧业务活跃,则SN通知MN存在活跃业务,不能悬挂RRC连接。
2)如果所述第二节点侧的业务处于第一状态,则所述第一节点接收所述第二节点发送的第三通知消息,所述第三通知消息用于向所述第一节点通知能够悬挂RRC连接。
例如:如果SN侧业务不活跃,SN通知MN可以立即悬挂RRC连接。
3)如果所述第二节点侧的业务处于第一状态,则所述第一节点接收所述第二节点配置的第二定时器,启动所述第二定时器;如果在所述第二定时器运行期间,所述第二节点侧出现了处于所述第一状态的业务,则所述第一节点接收所述第二节点发送的第一指示消息,所述第一指示消息用于向所述第一节点指示停止所述第二定时器;其中,如果在触发停止所述第二定时器之前,所述第二定时器超时,则所述第一节点向终端设备发送所述第一悬挂命令。
例如:如果SN侧业务不活跃,SN配置给MN一个定时timer 2,MN收到timer 2就启动该timer 2,如果超时,则MN下发悬挂RRC的命令给UE。如果在定时器运行期间,如果SN侧出现了活跃的业务,则SN会通知MN停止定时器timer 2。
步骤203:如果所述第一节点与所述第二节点协商需要悬挂RRC连接,则所述第一节点向终端设备发送第一悬挂命令,所述第一悬挂命令用于触发所述终端设备悬挂RRC连接以及进入RRC非激活状态。
例如:MN通过RRC release消息下发悬挂RRC的命令给UE,通知UE进入INACTIVE状态。
图3为本发明实施例的悬挂RRC连接的方法的流程示意图二,如图3所示,所述悬挂RRC连接的方法包括以下步骤:
步骤301:如果第二节点确定所述第二节点侧的业务处于第一状态,且所述第二节点与第一节点协商需要悬挂部分RRC连接或者所述第二节点确定需要悬挂部分RRC连接,则所述第二节点向终端设备发送第二悬挂命令,所述第二悬挂命令用于触发所述终端设备悬挂部分RRC连接以及进入部分RRC非激活状态;其中,所述悬挂部分RRC连接是指悬挂SCG部分的资源。
本发明实施例中,所述第一节点为双连接(DC)网络或者多连接(MC)网络中的主节点(MN),所述第二节点为双连接网络或者多连接网络中的辅节点(SN)。本发明实施例中是SN初始的RRC连接悬挂过程,具体地,SN侧检测出业务处于第一状态下,触发的RRC连接悬挂过程。这里,业务的第一状态是指业务处于非活跃状态,相对于第一状态而言,还具有一个状态称为第二状态,也即活跃状态。应理解,本发明以下实施例中提及到的业务未处于第一状态,是指业务处于活跃状态。
本发明实施例中,所述第二节点可以通过以下方式确定所述第二节点侧的业务处于第一状态:
方式一:如果所述第二节点连续接收到M个所述第二节点侧的业务承载对应的缓冲区大小等于0(也即BSR=0)的缓冲区状态报告,则确定所述第二节点侧的业务处于第一状态,M为正整数。
例如:SN侧连续收到M个SN侧业务承载对应的BSR=0的上报,则SN判决悬挂RRC连接,然后,通知MN并与MN协商该判决。
方式二:所述第二节点接收到所述第二节点侧的业务承载对应的首个缓冲区大小等于0的缓冲区状态报告时,启动第三定时器;如果在所述第三定时器运行期间,所述第二节点接收到所述第二节点侧的业务承载对应的缓冲区大小不等于0的缓冲区状态报告,则停止所述第三定时器;其中,如果在触发停止所述第三定时器之前,所述第三定时器超时,则确定所述第二节点侧的业务处于第一状态。
例如:SN侧收获到MN侧业务承载对应的第一个BSR=0的上报,启动定时器timer3,重新收到SN侧业务承载对应的BSR不等于0的上报,则停止定时器timer3。如果该定时器timer3超时,则SN判决悬挂RRC连接并通知MN并与MN协商该判决。
本发明实施例中,是否需要悬挂RRC连接,分为两种实现方式:
方式一:通过第一节点判决悬挂整个RRC连接还是部分RRC连接。具体地,如果所述第一节点侧的业务未处于第一状态,则所述第一节点确定需要悬挂部分RRC连接;如果所述第一节点侧的业务处于第一状态,则所述第一节点确定需要悬挂全部RRC连接。
方式二:通过第二节点判决悬挂部分RRC连接。具体地,在第二节点确定所述第二节点侧的业务处于第一状态后,第二节点直接判决悬挂部分RRC连接。
对于上述方式一而言,所述第二节点向所述第一节点发送第四通知消息,并与所述第一节点协商是否需要悬挂RRC连接,其中,所述第四通知消息用于向所述第一节点通知所述第二节点确定出需要悬挂RRC连接。1)如果所述第一节点侧的业务未处于第一状态,则所述第一节点确定需要悬挂部分RRC连接,所述第二节点接收所述第一节点发送的第五通知消息,所述第五通知消息用于向所述第二节点通知悬挂部分RRC连接。例如:如果MN存在活跃的业务,则MN判决UE进入部分RRC INACTIVE状态,也就是只悬挂SCG部分。MN会通知SN部分悬挂RRC连接,SN 使用SRB3悬挂SCG部分的资源。SN下发悬挂命令给UE后,通知MN侧关于UE进入部分RRC INACTIVE状态。2)如果所述第二节点与所述第一节点协商需要悬挂全部RRC连接,则通过所述第一节点向所述终端设备发送第三悬挂命令,所述第三悬挂命令用于触发所述终端设备悬挂全部RRC连接以及进入RRC非激活状态。这里,如果所述第一节点侧的业务处于第一状态,则所述第一节点确定需要悬挂整个RRC连接。例如:如果MN侧的业务不活跃,则MN可以判决悬挂整个RRC连接,并下发悬挂RRC的命令(例如RRC release消息)给UE,通知UE进入INACTIVE状态。此外,通知SN关于UE进入INACTIVE状态。
对于上述方式二而言,所述第二节点确定需要悬挂部分RRC连接后,向所述第一节点发送第七通知消息,所述第七通知消息用于向所述第一节点通知需要悬挂部分RRC连接。进一步,如果所述第二节点与所述第一节点协商需要悬挂部分RRC连接,则所述第二节点向终端设备发送第二悬挂命令(如通过SRB3给UE发送悬挂SCG部分的命令),所述第二悬挂命令用于触发所述终端设备悬挂部分RRC连接以及进入部分RRC非激活状态;其中,所述悬挂部分RRC连接是指悬挂SCG部分的资源。
图4为本发明实施例的悬挂RRC连接的方法的流程示意图三,如图4所示,所述悬挂RRC连接的方法包括以下步骤:
步骤401:MN检测到MN侧的业务不活跃,并通知给SN。
步骤402:MN与SN协商是否悬挂RRC连接,如果协商悬挂RRC连接,则执行步骤403,否则结束本流程。
这里,1)如果SN侧业务活跃,SN通知MN存在活跃业务,不能悬挂RRC连接。2)如果SN侧业务不活跃,SN通知MN可以立即悬挂RRC连接。3)如果SN侧业务不活跃,SN配置给MN一个定时timer 2,MN收到timer 2就启动该timer 2,如果超时,则MN下发悬挂RRC的命令给UE。如果在定时器运行期间,如果SN侧出现了活跃的业务,则SN会通知MN停止定时器timer 2。
步骤403:MN下发悬挂命令给UE,触发UE进入INACTIVE状态。
图5为本发明实施例的悬挂RRC连接的方法的流程示意图四,如图5所示,所述悬挂RRC连接的方法包括以下步骤:
步骤501:SN检测到SN侧的业务不活跃,并通知给MN。
步骤502:SN与MN协商是否悬挂RRC连接,如果协商悬挂全部RRC连接,则执行步骤503;如果协商悬挂部分RRC连接,则执行步骤504;否则结束本流程。
这里,通过MN决策是否悬挂RRC连接的方式,包括:1)如果MN侧业务也不活跃,则MN可以判决悬挂整个RRC连接;2)如果MN侧存在活跃的业务,则MN判决悬挂部分RRC连接,也就是只悬挂SCG部分。
通过SN决策是否悬挂RRC连接的方式,包括:如果SN检测到SN侧的业务不活跃,则SN直接决策悬挂部分RRC连接,然后通知给MN在SN侧进入了非激活状态了(也即部分INACTIVE状态)。
步骤503:MN或者SN下发悬挂命令给UE,触发UE进入INACTIVE状态。
这里,如果是MN决策是否悬挂RRC连接,则由MN下发悬挂命令给UE,如果是SN决策是否悬挂RRC连接,则由SN下发悬挂命令给UE。
步骤504:SN下发悬挂命令给UE,触发UE进入部分INACTIVE状态。
