Description

通信方法和通信装置
本申请要求于2020年03月18日提交中国国家知识产权局、申请号为202010192279.3、申请名称为“通信方法和通信装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种通信方法和通信装置。
背景技术
第五代移动通信网络(即5G)系统新引用了条件切换(Conditional Handover,以下简称CHO)机制。该CHO机制不同于传统切换机制,基站给用户设备(User Equipment,UE)配置一个比较低的预切换门限,当UE信号强度到达此门限后,向基站报告。基站决定执行CHO,并通知UE的邻居基站进行相关的切换准备工作,包括预留资源等。基站将为UE再配置一个切换执行门限(高门限),并一并将该切换执行门限及备选目标切换小区的配置信息发送给UE。UE收到切换执行门限后,当发现实测信号强度达到此实际切换门限后,将直接执行切换到目标小区的操作,而无需再向基站汇报后等待基站决定后才切换。
然而,在一些场景中,引入CHO机制会带来一定的资源浪费,并增加信令负担。由于CHO机制配置后,UE可能一直游走在小区边缘,或者返回小区中心地区,导致实际切换门限不会达到,因此实际切换永远不会发生,但是为此给UE预留的系统资源将导被浪费。另外,采用CHO机制需要UE在达到预切换门限时就上报,相比于传统的方法只在达到实际切换门限上报,提前了UE测量报告上报的时间,增加了上报的频次和相应的信令负担。
现有通信标准并没有对何种情况下配置CHO机制、何种情况下取消CHO机制配置做出规定。但是显然不当的配置CHO机制会导致系统负担增加、切换性能下降、资源浪费等不良后果。因此需要一种新的配置CHO机制的方式,避免不当配置带来的不良后果。
发明内容
本申请实施例公开了一种通信方法和通信装置,能够配置和使用条件切换机制,降低切换失败率和切换延时。
第一方面,本申请实施例提供了一种通信方法,包括:终端设备在满足第一触发条件和/或第二触发条件的情况下,发送测量报告;所述测量报告用于第一网络设备确定执行CHO或者不执行CHO,所述第一触发条件为所述终端设备发送所述测量报告所需满足的信号条件,所述第二触发条件为所述终端设备发送所述测量报告所需满足的速度条件。
需要说明的是,这里的第一网络和第二网络间的切换可以是跨越不同基站之间的切换,也可以是同一基站的不同扇区/小区(Cell)之间的切换,以及多连接/双连接(Dual Connectivity)架构下的不同小区/小区(Cell Group)组之间的切换。这些都属于本发明的覆盖范围,不再赘述。
经研究得知,在UE速度较低的场景中,采用CHO机制几乎没有什么性能提升。相反, 额外的提前准备工作,增加了不必要的资源浪费和UE发送测量报告的负担。对于某些特定场景,UE保持一定速率的持续运动状态下,比如高速公路、火车等接入场景,UE的切换发生概率很高,通过CHO提前配置切换资源和UE自主执行切换条件,对于降低切换延时和成功率是很有意义的。由此可以得出:(1)、对于运动速度较高的UE,配置CHO是有益的;(2)、对于运动速度较低的UE,尽量减少CHO配置,有益于减少不必要的系统资源浪费;(3)、对于某些特定场景,如UE保持一定高速率的持续运动状态下,配置CHO是必要和有益的。终端设备向第一网络设备发送其运动状态信息,该第一网络设备根据该运动状态信息可确定该终端设备的运动状态,进而根据该终端设备的运动状态确定是否执行CHO。示例性的,在终端设备的速度超过某个速度阈值是,第一网络设备执行CHO;否则,不执行CHO。

在一个可选的实现方式中,所述第一触发条件包括第三代合作计划(3rd generation partnership project,3GPP)无线资源控制协议RRC定义的至少一种测量事件。本申请实施例的一个主要原理是终端设备在同时满足3GPP 38.331 RRC协议中定义的测量事件A3,A5和第二触发条件时,向第一网络设备发送测量报告。应理解,第一触发条件可以是3GPP 38.331 RRC协议中定义的向第一网络设备发送测量报告所需满足的触发条件,是可以是基于其他测量事件所定义的条件,这里不再详述。

具体实施方式
本申请的说明书实施例和权利要求书及上述附图中的术语“第一”、“第二”、和“第三”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元。方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。“和/或”用于表示在其所连接的两个对象之间选择一个或全部。例如“A和/或B”表示A、B或A+B。
本申请实施例公开了通信方法和通信装置,结合终端设备的运动状态和终端设备接收到的当前所处小区(对应于第一网络设备)的信号强度和/或相邻小区(对应于第二网络设备)的信号强度来决定是否执行条件切换,能够更合理地配置和使用条件切换机制,降低切换失败率和切换延时。为了更好理解本申请实施例公开的通信方法和通信装置,下面先对本申请实施例适用的网络构架进行描述。本申请实施例公开的方法可以应用于5G新无线接入技术(New RAT(radio access technology),NR)系统;也可以应用于其它通信系统。下面先介绍本申请实施例公开的方法所适用的一种网络架构。
请参阅图1,图1是本申请实施例公开的一种网络构架示意图。如图1所示,该网络构架适用于小区切换场景,即通过终端设备从当前接入的小区切换至另一个小区的场景。网络设备是网络侧的一种用于发射或接收信号的实体,如gNB。终端设备是用户侧的一种用于接收或发射信号的实体,如手机。由于基站和UE的应用场景较多,下面以基站作为网络设备的示例,以用户设备(user equipment,UE)作为终端设备的示例。如图1所示,该网络架构包括小区1(对应于第一网络设备)和小区2(对应于第二网络设备),该小区1中接入的UE包括UE1、UE2以及UE3,该小区2中接入的UE包括UE4、UE5以及UE6。在该通信系统中,当UE从一个小区移动至另一个小区后,需要切换至新的小区。图1中,UE2位于小区1的边缘,当UE2接收到的小区1的信号强度大于接收到的小区2的信号强度时,UE可以从小区1切换至小区2,即接入小区2。可以理解,对应一个UE来说,当其满足小区切换条件时,可以从其当前接入的小区切换至另外的小区。
5G系统新引用了CHO机制。在一些实施例中,基站给UE配置一个比较高的预切换门限(高门限),当UE信号强度到达此门限后,向基站报告;基站决定执行CHO,并通知UE的邻居基站进行相关的切换准备工作,包括预留资源等,基站将为UE再配置一个切换执行门限(低门限),并将该切换执行门限及备选目标切换小区的配置信息发送给UE。UE收到切换执行门限后,当发现实测信号强度达到此切换执行门限后,将直接执行切换到目标小区的操作,而无需再向基站汇报后等待基站决定后才切换。下面介绍一下条件切换机制的主要流程。
图2为本申请实施例提供的一种条件切换交互流程图。如图2所示,该方法可包括:
201、终端设备向第一网络设备发送测量报告。
该第一网络设备根据该测量报告,确定执行CHO或者不执行CHO。可选的,终端设备在检测到来自第一终端设备的信号的强度低于预切换门限之后,向第一网络设备发送测量报告。可选的,终端设备在检测到来自第二终端设备的信号的强度高于预切换门限之后,向第一网络设备发送测量报告。终端设备可以是手机等能通过基站等网络设备进行通信的设备,第一网络设备可以是终端设备所接入的小区对应的网络设备,第二网络设备可以是与该终端设备接入的小区相邻的小区对应的网络设备。举例来说,第一网络设备和第二网络设备为两个相邻的基站。
202、第一网络设备根据测量报告,确定执行CHO。
203、第一网络设备向第二网络设备发送预切换请求。
该预切换请求用于通知第二网络设备(对应于终端设备的邻居基站)进行相关的切换准备工作,包括预留资源等。
204、第二网络设备进行切换准备工作。
205、第二网络设备向第一网络设备发送确认信息。
该确认信息指示该第二网络设备已完成切换准备工作。
206、第一网络设备向终端设备发送条件切换配置信息。
该条件切换配置信息包括切换执行门限及第二网络设备(即备选目标切换小区)的配置信息。该切换执行门限可以是一个信号强度阈值。
207、终端设备在检测到信号满足切换执行门限的情况下,切换至第二网络设备。
切换至第二网络设备可以理解为终端设备从当前接入的小区切换至另一个小区。终端设备和第二网络设备可以执行同步、随机接入等操作完成小区切换。
本申请实施例中,采用CHO机制,在满足预切换门限时向第一网络设备发送测量报告,以便于该第一网络设备通知第二网络设备进行切换准备工作,终端设备在满足切换执行门限时,直接切换至第二网络设备,不需要通知该第一网络设备;减少了切换失败的概率,并在一定程度上降低了切换的延时。
然而,在一些场景中,引入CHO机制会带来一定的资源浪费,并增加信令负担。由于CHO机制配置后,UE可能一直游走在小区边缘,或者返回小区中心地区,导致实际切换门限不会达到,因此实际切换永远不会发生,但是为此给UE预留的系统资源将导被浪费。另外,采用CHO机制需要UE在达到预切换门限时就上报,相比于传统的方法只在达到实际切换门限上报,提前了UE测量报告上报的时间,增加了上报的频次和相应的信令负担。
现有通信标准并没有对何种情况下配置CHO机制、何种情况下取消CHO机制配置做出规定。但是显然不当的配置CHO机制会导致系统负担增加、切换性能下降、资源浪费等不良后果。因此需要一种新的配置CHO机制的方法,避免不当配置带来的不良后果。下面介绍本申请实施例提供的能够更合理的应用CHO的通信方法。
图3为本申请实施例提供的一种通信方法流程图。如图3所示,该方法可包括:
301、终端设备接收来自第一网络设备的测量配置信息。
上述测量配置信息用于配置上述终端设备向上述第一网络设备发送测量报告的触发条件,上述测量配置信息包括至少一个速度阈值和/或至少一个信号强度阈值。可选的,上述 测量配置信息包括第一阈值和第二阈值中的至少一个,以及第一速度阈值和第二速度阈值中的至少一个。可选的,上述第一阈值和上述第二阈值均为信号强度阈值,上述第一阈值或者上述第二阈值可对应于图2中的预切换门限。可选的,终端设备根据上述测量配置信息,配置第一触发条件和/或第二触发条件。
302、终端设备在满足第一触发条件和/或第二触发条件的情况下,发送测量报告。
上述测量报告用于第一网络设备确定执行CHO或者不执行CHO。上述第一触发条件包括无线资源控制协议RRC定义的至少一种测量事件,还可以包括其他测量事件,本申请不作限定。示例性的,上述第一触发条件包括上述终端设备检测到来自上述第一网络设备的信号的强度小于第一阈值,和/或,上述终端设备检测到来自第二网络设备的信号的强度不小于第二阈值。该第一阈值可以是-120dBm、-100dBm、-90dBm、-80dBm、-75dBm等,该第二阈值可以是-80dBm、-75dBm、-70dBm、-60dBm等。上述第二触发条件包括上述终端设备的瞬时速度超过第一速度阈值和/或上述终端设备的平均速度超过第二速度阈值。该第一速度阈值可以是10千米每小时、15千米每小时、30千米每小时、45千米每小时等,该第二速度阈值可以是10千米每小时、15千米每小时、30千米每小时、45千米每小时等,本申请不作限定。可选的,上述第二触发条件还可以是上述终端设备未获知其当前的运动状态。所述终端设备未获知其当前的速度可以是以下任一种情况:1、终端设备未去获取当前速度;2、终端设备去获取当前速度了,但未获取到当前速度;3、终端设备获取到了当前速度但是当前速度属于非法值(超过正常取值范围)等。在一些实施例中,终端设备在满足第一触发条件且其速度低于速度门限(对应于第一速度阈值或第二速度阈值)的情况下,向第一网络设备发送测量报告。在一些实施例中,终端设备为手机,第一网络设备为该终端设备当前接入的小区对应的基站,第二网络设备为该小区相邻的小区对应的基站。
可选的,上述测量报告包括上述终端设备检测到的来自上述第一网络设备的信号的强度,和/或,上述终端设备检测到的来自第二网络设备的信号的强度。在一些实施例中,上述第一触发条件为上述终端设备检测到来自上述第一网络设备的信号的强度小于第一阈值;终端设备在执行步骤302之前,可检测来自上述第一网络设备的信号的强度,进而确定是否满足第一触发条件。在一些实施例中,上述终端设备检测到来自第二网络设备的信号的强度不小于第二阈值;终端设备在执行步骤302之前,可检测来自上述第二网络设备的信号的强度,进而确定是否满足第一触发条件。在实际应用中,终端设备可通过全球卫星导航系统(Global Navigation Satellite System,GNSS),例如北斗卫星导航系统来获取速度信息;也可以通过速度传感器、加速度传感器等测量得到其速度。在一个实施例中,终端设备在确定满足上述第一触发条件之后,根据上述终端设备的运动状态来确定是否满足上述第二触发条件。
303、终端设备接收第一网络设备发送的条件切换配置信息。
条件切换配置信息用于配置终端设备切换至第二网络设备的条件和/或终端设备切换至第二网络设备所需的信息。示例性的,该条件切换配置信息包括切换执行门限(即终端设备切换至第二网络设备的条件)及第二网络设备(即备选目标切换小区)的配置信息(对应于终端设备切换至第二网络设备所需的信息)。
本申请实施例中,终端设备在满足第一触发条件和/或第二触发条件时,向第一网络设 备发送测量报告;能够更合理地配置和使用条件切换机制,降低切换失败率和切换延时。
图3中描述了终端设备(即终端侧)执行的方法流程,下面描述第一网络设备(即网络侧)执行的方法流程。

401、第一网络设备发送测量配置信息;上述测量配置信息用于配置终端设备向上述第一网络设备发送测量报告的触发条件,上述测量配置信息包括至少一个速度阈值和/或至少一个信号强度阈值,上述测量报告用于上述第一网络设备确定执行CHO或者不执行CHO。
可选的,上述测量配置信息用于配置上述终端设备向上述第一网络设备发送测量报告所需满足的第一触发条件和/或第二触发条件,上述第一触发条件包括3GPP RRC定义的至少一种测量事件,还可以包括其他测量事件,本申请不作限定。示例性的,上述第一触发条件包括上述终端设备检测到来自上述第一网络设备的信号的强度小于第一阈值,和/或,上述终端设备检测到来自第二网络设备的信号的强度不小于第二阈值,上述第二触发条件包括上述终端设备的瞬时速度超过第一速度阈值和/或上述终端设备的平均速度超过第二速度阈值,上述至少一个速度阈值包括上述第一阈值和/或上述第二阈值,上述至少一个信号强度阈值包括上述第一速度阈值和/或上述第二速度阈值。

图3和图4分别从终端侧和网络层描述了实现CHO的通信方法流程。下面描述终端侧和网络侧实现CHO的交互流程。图5为本申请实施例提供的另一种通信方法流程图。如图5所示,该方法可包括:
501、第一网络设备发送测量配置信息。
上述测量配置信息用于配置终端设备向上述第一网络设备发送测量报告的触发条件,上述测量配置信息包括至少一个速度阈值和/或至少一个信号强度阈值,上述测量报告用于上述第一网络设备确定执行CHO或者不执行CHO。可选的,步骤501可替换为:第一网络设备向终端设备发送测量配置信息和至少一个速度阈值;其中,上述测量配置信息用于配置上述终端设备向上述第一网络设备发送测量报告的触发条件,上述测量配置信息包括至少一个信号强度阈值。也就是说,第一网络设备可以分别发送测量配置信息以及速度阈值(也称速度门限)。示例性的,第一网络设备通过系统广播消息、无线资源控制(Radio Resource Control,RRC)等单独发送速度阈值。示例性的,第一网络设备将速度阈值和测量配置信息通过一并下发等方式发送给终端设备。在一些实施例中,第一网络设备为其对应的小区中的各终端设备发送相同的速度阈值,即各终端设备配置的速度阈值是相同。在一些实施例中,第一网络设备为其对应的小区中的各终端设备发送不同的速度阈值,即不同终端设备配置的速度阈值可能不同。
502、终端设备确定满足第一触发条件和/或第二触发条件。
503、终端设备向第一网络设备发送测量报告。
应理解,终端设备在其当前的速度(对应的第二触发条件)以及检测到的信号强度(对应于第一触发条件)同时满足条件切换的要求之后,向第一网络设备发送测量报告。也就是说,终端设备在满足第一触发条件和/或第二触发条件时,可触发向第一网络设备发送测量报告的操作。
504、第一网络设备根据测量报告,确定执行条件切换。
步骤504的实现方式可以类似于图2中的步骤202。
505、终端设备接收来自第一网络设备的条件切换配置信息。
该条件切换配置信息包括切换执行门限及第二网络设备(即备选目标切换小区)的配置信息。
506、在检测到信号满足切换执行门限的情况下,切换至第二网络设备。
应理解,若第一网络设备确定执行CHO,则第一网络设备、第二网络设备以及终端设备可执行图2中的切换流程,以实现小区切换,即从第一网络设备切换至第二网络设备。
本申请实施例中,终端设备向第一网络设备发送测量报告,不仅需要满足一定的信号强度条件,还需要其自身的运动状态满足一定的条件,这样可以减少测量报告的发送,节省信令资源。
前述实施例的主要原理是进一步限定终端设备向第一网络设备发送测量报告所需满足的触发条件,例如增加了第二触发条件。本申请实施例还提供了另一种可更合理的应用CHO的通信方法,该通信方法的主要原理是:终端设备向第一网络设备发送测量报告和其自身的运动状态信息,该第一网络设备根据该测量报告和该运动状态信息确定是否执行CHO。下面结合附图来详述该通信方法的流程。

可选的,上述终端设备在满足第一触发条件的情况下,向上述第一网络设备发送上述测量报告以及上述运动状态信息;上述第一触发条件包括3GPP RRC定义的至少一种测量事件。可选的,上述运动状态信息包括上述终端设备的瞬时速度、上述终端设备的平均速度、速度指示信息中的至少一项;上述速度指示信息用于指示上述终端设备的运动状态。

603、终端设备在检测到信号满足切换执行门限的情况下,切换至第二网络设备。
步骤602和步骤603是可选的,而非必要的。在一些实施例中,第一网络设备根据测量报告以及上述终端设备的运动状态信息,确定不执行CHO;该第一网络设备在确定不执行CHO时,该第一网络设备不会向终端设备发送条件切换配置信息。在这些实施例中,终端设备就不会执行步骤602和步骤603。
本申请实施例中,终端设备向第一网络设备发送测量报告以及该终端设备的运动状态 信息,以便于该第一网络设备能够更合理地配置和使用条件切换机制,降低切换失败率和切换延时。

图7为本申请实施例提供的另一种通信方法流程图。如图7所示,该方法可包括:
701、第一网络设备接收来自终端设备的测量报告以及上述终端设备的运动状态信息。
可选的,上述运动状态信息包括上述终端设备的瞬时速度、上述终端设备的平均速度、速度指示信息中的至少一项;上述速度指示信息用于指示上述终端设备的运动状态。
该运动状态信息可以是终端设备当前的瞬时速度、该终端设备在过去一段时间(例如1小时、10分钟等)的平均速度的两者之一或者全部;也可以是终端设备当前的速度状态指示,表明其运动状态处于预先设定的几种速度挡位之一(如高、中、低等三档,或者多档分类);还可以是终端设备当前处于“一定高速率的持续运动状态”的指示。第一网络设备可以根据终端设备上报的瞬时速度、平均速度,可以更好的了解终端设备的运动状态,例如如果终端设备当前的速度和平均速度都很高,说明该终端设备处在“持续的高速运动“状态中,而此种情况下,该终端设备发生切换、连续切换的概率非常高,第一网络设备可以为该终端设备配置CHO。可选的,终端设备可以根据对其速度的综合统计信息,判断其是否处于“一定高速率的持续运动状态”,并向第一网络设备发送指示。本申请实施例中,运动状态信息还可以包括其他指示终端设备的运动状态的信息,本申请不作限定。
702、第一网络设备根据上述测量报告和上述运动状态信息,确定执行CHO或者不执行CHO。
可选的,第一网络设备根据上述运动状态信息,确定上述终端设备处于高速运动状态的情况下,确定执行CHO。举例来说,第一网络设备根据终端设备的运动状态信息确定该终端设备的平均速度大于120千米每小时,确定执行CHO。应理解,第一网络设备还可以采用其他方式根据终端设备的运动状态信息以及测量报告,确定是否执行CHO,本申请不作限定。
703、第一网络设备向终端设备发送条件切换配置信息。
该条件切换配置信息包括切换执行门限及第二网络设备(即备选目标切换小区)的配置信息。

803、终端设备接收来自第一网络设备的条件切换配置信息。
该条件切换配置信息包括切换执行门限及第二网络设备(即备选目标切换小区)的配置信息。
804、在检测到信号满足切换执行门限的情况下,切换至第二网络设备。
应理解,若第一网络设备确定执行CHO,则第一网络设备、第二网络设备以及终端设备可执行图2中的切换流程,以实现小区切换,即从第一网络设备切换至第二网络设备。
