Description

RAN通知范围信息的通知方法及装置 技术领域
本公开涉及移动通信技术领域,例如涉及一种RAN通知范围信息通知方法及装置。
背景技术
随着小数据量传输业务越来越多,比如保活业务和机器类通信(Machine Type Communication,MTC)设备的业务等等,为了节省功率损耗,减少信令开销,相关技术中引入了非激活(inactive)状态。在inactive状态下,允许用户终端(User Equipment,UE)在无线接入网(Radio Access Network,RAN)通知的一定范围内移动,而不需要向核心网上报,这种情况下,当下行数据、下行信令或者非接入层(Non-access Sratum,NAS)消息到达时,RAN需要发起寻呼流程以寻呼UE。为了支持这个寻呼流程,需要将基于RAN通知范围(RAN based Notification Area,RNA)的信息配置给终端,以便终端在这个基于RNA信息中移动而无需上报给网络侧,但移动出这个RNA时,才需要让网路侧感知。
如果终端不能获知RNA信息,那么,即使终端处于inactive状态下,只要发生移动就会上报网络侧,这样,势必造成信令不必要的频繁切换,也浪费了系统资源。
发明内容
本公开提供一种RAN通知范围信息的通知方法及装置,能够实现消除信令不必要的频繁切换,从而节省系统资源。
本公开提供了一种无线接入网RAN通知范围信息通知方法,包括:
网络侧节点按照预先设置的策略确定RAN通知范围RNA信息;
网络侧节点将确定的RNA信息发送给终端;
其中,策略包括以下之一:
采用网络侧配置的方式表示RNA信息;或者,
根据终端的相关信息确定RNA信息的表示方式。
本公开还提供了一种无线接入网RAN通知范围信息通知装置,包括:确定 模块,通知模块;其中,
确定模块,设置为按照预先设置的策略确定RNA信息;
通知模块,设置为将确定的RNA信息发送给终端;
其中,策略包括以下之一:
采用网络侧配置的方式表示RAN通知范围信息;或者,
根据终端的相关信息确定RNA信息的表示方式。
本公开提供的RAN通知范围信息的通知方法及装置,通过将RAN通知范围信息告知终端,可以实现消除信令不必要的频繁切换,从而节省了系统资源。当策略中存在多种形式的RNA信息的表示方式时,还可以基于终端的相关信息如业务特性或移动特性等信息,确定RAN通知范围信息,实现了对RNA信息的优化。

具体实施方式
业界对于RNA信息的构成已达成一些共识,比如:一个RNA信息可以包括一个小区或者多个小区的信息,其中,多个小区可以归属于不同基站;一个RNA可以小于一个跟踪区域(Tracking area,TA)。但是对RNA信息的具体构成并没有提供相应的内容。
可以引入一个新的标识,如无线接入网区域跟踪(RAN tracking area,RTA)标识,这样,RNA信息可以采用RTA列表(RTA list)来表示;也可以采用一个TA来表示RNA信息;还可以采用一个小区列表(Cell list)来表示RNA信息。
图1为本实施例提供的一种RAN通知范围信息的通知方法的流程示意图,如图1所示,该方法可以包括如下步骤:
在步骤100中,网络侧节点按照预先设置的策略确定RAN通知范围信息。
其中,RAN通知范围,就是UE在这个范围内移动无需要上报给网络侧,比如执行类似于长期演进(Long Term Evolution,LTE)系统空闲态下的小区重选机制。
其中,上述预先设定的策略包括以下之一:采用默认的方式表示RAN通知范围信息;即采用网络侧配置的方式表示RNA信息。或者,
根据终端的相关信息确定RAN通知范围信息的表示方式。
其中,终端的相关信息可以包括业务特性和移动特性等信息中的至少一个。网络侧节点可以是RAN节点,例如基站,该基站可以是eNB,或5G中的gNB等。
可选地,当上述策略为采用默认的方式表示RAN通知范围信息时,网络侧节点将确定的RAN通知范围信息发送给终端包括:
网络侧节点默认采用RTA信息、Cell信息和TA信息中的至少一个表示RAN通知范围信息。
如果网络侧没有配置默认的方式,终端上报异常,此时,默认非激活态的终端支持采用RTA信息、Cell信息和TA信息中的至少一个所表示的RAN通知范围信息;或者,
当网络侧节点默认采用RTA信息和Cell信息中的至少一个表示RAN通知范围信息,如果网络侧没有配置上述策略,默认采用TA信息表示RAN通知范围信息;
可选地,当上述策略中包括采用RTA信息和Cell信息表示RAN通知范围信息时,网络侧可以根据终端的相关信息,如业务特性和移动特性等信息中的至少一个,确定其中一种信息来表示RAN通知范围信息。
可选地,终端,即UE,的业务特性包括以下至少之一:时延要求、可靠性要求和速率要求,例如,包括窄带物联网业务、超可靠低时延业务和增强型移动宽带业务等至少之一,对于终端的不同的业务特性可以配置不同范围级别的RNA信息。比如:对于窄带物联网业务和超可靠低时延业务,可以采用较小范围的信息来表示RNA信息,如使用Cell信息来表示;再如:对于增强型移动宽带业务,可以采用范围较大的信息来表示RNA信息,例如采用RTA信息或TA 信息来表示。
可选地,UE的移动特性包括UE的移动轨迹信息,网络侧节点如基站可以根据UE的移动轨迹信息,估算出在跟踪区域列表中的更小的寻呼区域范围,确定出这个更小寻呼范围中的基站列表。也就是说,对于当前配置的寻呼区域,通过优化RNA信息确定更小的寻呼区域,比如:假设基站通知UE的寻呼区域包括Cell1,Cell2和Cell3,根据UE的移动特性,如UE的移动特性是低速,先寻呼的区域可以为当前的登记小区,比如Cell1。
可选地,上述策略还可以是:网络侧节点根据接收到的终端上报的终端自身支持的RNA表达方式确定RAN通知范围信息的表示方式。
例如,网络侧节点接收终端上报的终端自身支持的RNA表达方式,网络侧节点按照终端支持的RAN表达方式配置非激活态终端的RNA信息。
其中,Cell信息可以包括一个小区的信息或UE详细的小区列表信息(a cell or UE specific cell list)。其中,UE specific cell list的范围信息至少包括以下之一:多个Cell属于一个基站或者多个基站;多个Cell属于一个TA或者多个TA。
其中,RTA信息可以包括一个RTA的信息或UE详细的RTA列表信息(a RTA or UE specific RTA list)。
其中,TA信息可以包括一个TA的信息或TA列表信息(a TA or TA list)。
可选地,终端支持的RAN表达方式包括以下至少之一:
采用RTA信息表示的RAN通知范围信息;
采用Cell信息表示的RAN通知范围信息;
采用TA信息表示的RAN通知范围信息。
可选地,RNA信息可以是遵循以下一项:
一个Cell归属于一个RTA;
一个Cell归属于多个不同业务RTA;
一个RTA可以包含一个Cell或者多个Cell;
一个RTA包含的多个Cell可以属于一个基站或者多个基站;
如果一个RTA包含多个Cell,这些Cell可以属于一个TA或者多个TA;
如果一个RTA包含多个Cell,这些Cell应该在一个TA列表(list)范围内。
可选地,如果策略中存在多种形式的RNA信息的表示方式,可以包括:基于终端的相关信息如业务特性和移动特性等信息中的至少一种,确定其中一种信息来表示RAN通知范围信息。
在步骤102中,网络侧节点将确定的RNA信息发送给终端。
例如,网络侧节点向终端发送非激活态指示(inactive indication),并将确定的RNA信息下发给终端。
网络侧节点,如基站,可以通过下行空口消息将确定的RAN通知范围信息发送给终端。
其中,下行空口消息可以包括但不限于:公共消息和专用消息等。
本实施例给出了完整的将RAN通知范围信息告知终端的方案,消除了信令不必要的频繁切换,从而节省了系统资源。
当策略中存在多种形式的RNA信息的表示方式时,可以基于终端的相关信息如业务特性和移动特性等信息中的至少一种信息,确定一种较佳的信息表示方式来表示RAN通知范围信息,实现了对RNA信息的优化。
可选地,如果网络侧节点下发的RAN通知范围信息采用多种形式表示,还可以包括:终端基于相关信息如业务特性和移动特性等信息中的至少一种信息,确定其中一种信息来表示RAN通知范围信息。
当终端发现自身进入新的RNA范围,本实施例的方法还包括:终端发起RAN侧位置更新流程,该流程可以包含以下三种类型之一:
RNA信息采用RTA信息表示的位置更新流程,具体实现请参见图3所示。RNA信息采用TA信息表示的位置更新流程,具体实现请参见图4所示。
RNA信息采用Cell信息表示的位置更新流程,具体实现请参见图5所示。
本实施例的方法还包括:RAN寻呼优化处理:
如果网络侧节点和终端都支持采用Cell信息表示RAN通知范围信息,那么,当核心网下行数据或者下一代网络控制面(Next Generation Control,NGC)接口信令或者NAS信令到达时,RAN寻呼在Cell信息中包含的Cell中寻呼;也即当所述网络侧从核心网接收到数据或者网络控制面NGC接口信令或者非接入层NAS信令时,RAN网络节点在RNA范围内进行寻呼,其中,RNA范围内的是指属于RNA信息对应的小区范围。如果寻呼超时,RAN可以扩大到在RTA信息或TA信息显示的跟踪区域内寻呼。其中,RTA信息或TA信息显示的跟踪区域是由终端的移动轨迹决定的。NGC接口可以为5G中的核心网与gNB之间的控制面接口。
结合以下实施例对本实施例提供方法进行说明。3GPP系统可以是LTE系 统,或增强型LTE系统,或5G新系统,本实施例以LTE接入网的网元为演进基站eNB为例,核心网以CN为例,其中CN包括移动性管理实体(Mobility Management Entity,MME)和服务网关(Serving GateWay,S-GW)。
图2为本实施例提供RAN通知范围信息的通知方法的实施例的流程示意图,本实施例中假设eNB根据UE的移动轨迹确定RNA信息后,将RNA信息通知给UE,如图2所示,该方法包括:
在步骤200中,UE上报自身支持采用RTA信息表示RNA信息。
本实施例中,UE向eNB上报UE自身支持采用a RTA or UE specific RTA list表示RNA信息的指示;
本实施例中,假设UE的业务模型为增强型移动宽带业务,UE可以通过系统消息获取当前小区的RTA标识为RTA1,假设UE移动轨迹涉及Cell11、Cell12和Cell31,其中Cell11,Cell12归属于RTA1,Cell13归属于RTA2。
在步骤201中,eNB根据UE的移动特性确定RNA信息。
eNB根据UE的移动轨迹得出UE的RNA信息是由RTA1和RTA2组成,而且,RTA1包含Cell11和Cell12,RTA2包含Cell13。
在步骤202中eNB通过下行空口消息将确定的RNA信息告知UE。
本实施例中,RNA信息由RTA list方式表示,例如RTA list中包含有RTA1和RTA2。
图3为本实施例提供的一种RAN通知范围信息更新的流程图,本实施例中,RNA信息采用RTA信息表示,如图3所示,更新流程包括:
在步骤300中,在服务RAN节点即gNB1下UE的状态移动到非激活状态,在RRC连接释放(RRC connection release)消息中,服务RAN节点提供两个参数:UE文本指示(resume ID),以及UE自主移动范围RNA。这里,RNA的范围用RTA list表示。
在步骤301~步骤302中,UE移动到gNB2下,读取到gNB2的广播消息SIB1中携带的RTA,发现这个RTA不在UE保存的RTA list中,UE触发RNA更新(RNA update)流程。
在步骤303中,由于UE处于非激活态,UE要进行空口恢复流程,UE向gNB2上报RRC文本请求(RRC resume request)消息,该消息中携带标识UE上下文本的UE ID如resume ID,以及安全检查认证参数short mac-i。
这里,认证参数short mac-i传给gNB,gNB会用相关的加密参数和完整算 法,解码出认证参数short mac-i与自身保存的参数是否一致。
在步骤304中,gNB2发现没有UE的上下文本,于是通过resume ID获取到锚点gNB(anchor gNB)即gNB1,于是,向gNB1发起UE上下文本获取请求(UE context retrieve request),同样,其中携带有resume ID和short maci。
在步骤305中,gNB1通过short maci验证通过这个resume ID,确定没有下行数据传送,向gNB2发送UE上下文获取响应,其中携带有UE上下文本,和NGC路径切换流程指示(indication of path switch)。
在步骤306中,gNB2发送RRC连接文本(RRC connection resume)消息给UE,其中携带新的resume ID;UE收到这个消息进行UE上下文本激活操作。
在步骤307中,UE向gNB2回复RRC连接上下文完成RRC connection resume complete消息。该步骤可以省略。
在步骤308中,UE向gNB2发送RNA更新(RNA update)消息,其中携带RNA update的原因,如果有上行数据在缓存区中,还携带有数据待发送指示。
其中,gNB2收到RNA update消息,会注册该UE的位置,分配新的RTA list;如果数据待发送指示为真(true)或者收到路径切换(path switch)流程,gNB2指示(显示或者隐式)该UE处于连接态;如果数据待发送指示为假(false),gNB2指示UE进入非激活inactive态。
在步骤309中,gNB2向UE返回RNA更新接受(RNA update accept)消息,其中携带有新的RTA list,以及状态转换指示。
在步骤310中,gNB2发起NGC路径切换请求(path switch request)消息给NGC,其中携带gNB 1的标识id;NGC让gNB1释放该UE在NGC接口的相关文本。
在步骤311中,MME通过NGC接口向gNB2返回NGC路径切换请求回应(path switch request ack)消息。
在步骤312中,gNB2向gNB1发送UE文本释放消息,以指示gNB1释放UE空口相关文本。
在步骤313中,如果不是用户面数据的最后一包数据,gNB2通一个新的RRC专用消息(Dedicated signalling)给UE发送一个新的anchor gNB的标识。
在步骤314中,等gNB2收到最后一个包,网络侧再指示该UE进入非激活态。
图4为本实施例提供的另一种RAN通知范围信息更新的流程图,本实施例 中,RNA信息采用TA信息表示,如图4所示,该流程包括:
在步骤400中,假设UE通过RRC连接过程处于连接态,通过专用信令获取a TA或TA list配置,之后再回退到inactive状态。比如:eNB1向UE发送的RRC连接释放(RRC connection release)消息,其中携带有a TA或TA list。
在步骤401中,UE通过eNB2的Cell2的广播消息读取到UE当前进入的TA(new TA)不同于UE自身保留的表示RNA信息的TA或者不在UE保留的表示RNA信息的TA list中。
在步骤402~步骤403中,UE启动一个定时器,通过grant free方式向eNB2发起RNA级别的位置更新请求,该请求中携带有被访问的TA、UE移动信息、UE业务信息中的至少一种信息,以及UE id。
如果定时器超时没有收到到响应,则重新发送RNA级别位置更新请求。如果超过一定次数仍未收到响应,如3次,则发起RRC连接请求消息。
在步骤404中,目标eNB2获取UE的RNA更新请求消息,发现没有UE上下文,通过UE id获取锚点eNB(anchor eNB),如eNB1,的标识。
其中,携带RNA更新消息的理由是位置更新原因值,不是上行数据到达请求。
在步骤405中,目标eNB即eNB2向锚点eNB,即eNB1,发送UE上下文本请求或者位置更新请求。
在步骤406中,锚点eNB1向目标eNB2发送UE上下文本响应或位置更新响应。
在步骤407中,目标eNB2确定新的a TA或TA list。
本步骤中,确定新的a TA或TA list,可以通过后台配置实现,或者基于UE移动特性如移动轨迹和移动速度等确定。实现方式可参见图1所示,此处不再赘述。
在步骤408中,eNB2向UE返回RAN级别位置更新接受消息。
图5为本实施例提供的又一种RNA信息更新的流程图,本实施例中,RNA信息采用Cell信息表示,如图5所示,包括:
在步骤500中,假设UE通过RRC连接过程处于连接态,通过专用信令获取a TA或TA list配置。
在步骤501中,UE通过eNB2的广播消息读取当前进入的Cell不同于UE保留的表示RNA信息的Cell或者不在UE保留的表示RNA信息中的Cell list。
在步骤502中,UE通过预定配置的公共资源发起RAN级别位置更新请求,其中,该请求中可以携带被访问的Cell、UE移动信息和UE业务信息中的至少一种信息,这个特定资源可以通过前导码preamble标识,实现为UE的RAN级别位置更新消息预留特定的资源。。
在步骤503中,发现没有UE上下文,通过UE id获取锚点eNB1的标识。
在步骤504中,向eNB1发送RNA更新(RNA update)请求,其中携带有UE id、UE业务、UE移动信息和eNB2数据地址信息中的至少一种信息。
如果eNB1收到下行数据,可以通过eNB2的数据地址信息,直接将下行数据路由到eNB2上,同时要求eNB2进行路径切换。
在步骤505中,锚点eNB1获取UE的RNA更新消息,确定新的a Cell或Cell list。这里,确定新的a TA或TA list,可以通过后台配置实现,或者基于UE移动特性如移动轨迹和移动速度等确定。实现方式可参见图1所示,此处不再赘述。
在步骤506中,eNB1向eNB2返回RAN级别位置更新接受(RNA update Accept)消息,消息中携带有UE id和确定的a Cell或Cell list。
在步骤507中eNB2向UE发送preamble和RAN级别位置更新接受消息。
如果网络侧节点和终端都支持采用Cell信息即a cell or UE specific cell list表示RAN通知范围信息,那么,当核心网下行数据或者NGC接口信令或者NAS信令到达时,RAN寻呼在Cell信息显示的Cell中寻呼。如果寻呼超时,RAN可以扩大RTA list寻呼或者a TA或TA list中寻呼。其中,RTA list和TA list是由UE的移动轨迹决定的。
图6为本实施例提供的一种实现RAN寻呼的流程示意图,如图6所示,该流程可以包括:
在步骤600中,gNB1收到来自MME的下行数据或者NGC接口信令。
在步骤601中,gNB1进行小区级别的寻呼。
其中,gNB1获取该UE当前的表示RAN通知范围信息即a cell或UE specific cell list;gNB1启动寻呼定时器,并向获得的a cell or UE specific cell list发送寻呼消息。
其中,如果跨gNB,则发送X2分页(paging)消息给相关gNB,比如本实施例中的gNB1向gNB2发送X2 paging消息。
在步骤602中,假设寻呼不可达,比如寻呼定时器超时,gNB1仍未收到寻 呼响应,gNB1发起RAT级别的寻呼或者在TA list范围中寻呼。
其中,如果跨gNB,则发送X2 paging消息给相关gNB,X2 paging消息中携带的RTA list和TA list是由UE的移动轨迹确定的。本实施例中,假设gNB1向gNB2和gNB3发起X2 paging消息。
在步骤603中,假设寻呼不可达,gNB1获知NGC支持对inactive UE进行CN级别的寻呼,则将Cell list和RTAlist映射到相关的TAlist和TA中。
这里,可以通过核心网与gNB之间的NGC接口将NGC支持对inactive UE进行CN级别的寻呼的信息通知给gNB1。NGC支持对inactive UE进行CN级别的寻呼,具体通知时间可以是网元上电时互相告知,也可以是UE在专用态时告知gNB。
在步骤604中,gNB1发送相关的寻呼辅助信息给MME,其中包括步骤603中的相关的Cell list、gNB列表、TA list和TA list等信息中的至少一个。
本实施例还提供了一种计算机可读存储介质,存储有计算机可执行指令,所述计算机可执行指令用于执行本实施例任一项的RAN通知范围信息通知方法。
