图2为本申请实施例提供的一种传输信息的方法200的示意图,该方法200可以由基站和终端设备执行。为了便于后面描述,这里将该基站称为第一基站,该第一基站为任意一个基站,例如,该第一基站可以为如图1所示的网络设备,而该终端设备可以为如图1所示的任意终端设备。如图2所示,该方法200可以包括以下步骤。
S210,发送第一信息,即第一基站向终端设备发送第一信息。具体的,该第一基站可以通过多种方式向该终端设备发送该第一信息,例如,该第一基站可以直接或者间接发送该第一信息;或者,该第一基站也可以将其他设备发送的第一信息转发至终端设备,下面将结合图2至图4详细说明。
可选的,作为一个实施例,如图2所示,该S210可以表示第一基站直接向终端设备发送该第一信息。例如,该第一基站通过无线资源控制(Radio Resource Control,RRC)消息直接向所述终端设备发送所述第一信息。其中,该RRC消息可以为RRC连接重配置消息。
可选的,作为一个实施例,如图2所示,该S210还可以表示第一基站通过其他设备间接向该终端设备发送该第一信息。例如,该第一基站可以通过第二基站向所述终端设备发送所述第一信息,其中,该第二基站为除了第一基站以外的任意一个基站。下面将结合图3进行举例说明,图3示出了本申请实施例的第一基站通过第二基站向终端设备发送第一信息的方法的示意图。如图3所示,步骤210可以包括如下几种情况。
具体地,第一基站通过第二基站向终端设备发送第一信息可以包括:S211,发送第一信息,即第一基站通过N2接口向核心网设备发送该第一信息,之后继续执行S212。
S212,转发第一信息,即核心网设备将接收到的第一基站发送的第一信息,转发至第二基站,并继续执行S214。
S214,转发第一信息,即第二基站将接收到的第一信息转发至终端设备。
应理解,在上述过程中,第一基站通过核心网设备和第二基站向终端设备发送该第一信息,其中,该第一信息可以位于第一容器中,以便于核心网设备和第二基站将该第一信息透传至终端设备,在透传过程中,该核心网设备和第二基站对该第一容器不感知或不修改。可选的,该第一容器还可以包括RRC连接重配置消息,该RRC连接重配置消息包括该第一信息。
可选的,该第一基站过第二基站向终端设备发送第一信息还可以包括:S213,发送第一信息,即第一 基站通过Xn接口向该第二基站发送该第一信息,并继续执行S214。
S214,转发第一信息,即第二基站将接收到的第一信息转发至终端设备。
应理解,在上述过程中,第一基站通过第二基站向终端设备发送该第一信息,其中,该第一信息可以位于第一容器中,以便于第二基站将该第一信息透传至终端设备,在透传过程中,该第二基站对该第一容器不感知或不修改。可选的,该第一容器还可以包括RRC连接重配置消息,该RRC连接重配置消息包括该第一信息。
可选的,作为一个实施例,如图2所示,该S210还可以表示第一基站将其他设备发送的第一信息转发至该终端设备。例如,图4示出了根据本申请实施例的第一基站转发第一信息的示意图。
如图4所示,在S210之前,该方法200还可以包括:S230,发送第一信息,即核心网设备向第一基站发送第一信息,并继续执行S215。
可选的,该第一信息可以位于第二容器中,该第二容器用于该第一基站透传该第一信息至该终端设备,该第一基站不感知或不修改该第二容器内的内容。
S215,转发第一信息,即第一基站向终端设备转发第一信息。具体地,在S210中的第一基站向终端设备发送第一信息还可以包括:S215中的该第一基站将接收到的核心网设备发送的第一信息,转发至终端设备。
可选的,该核心网设备向终端设备发送第一信息还可以包括:该核心网设备向位于特定的存在报告区域(Presence Reporting Area,PRA)内的终端设备发送该第一信息,其中,该特定PRA也可以称为第一PRA,可以表示任意一个PRA。
应理解,第一基站通过上述任意方式向终端设备发送第一信息,以便于终端设备接收到该第一信息之后,继续执行S220。
S220,将第一信息传递至高于接入层(AS层)的协议层。具体地,终端设备接收到第一基站发送的第一信息,该终端设备可以将该第一信息直接传递至AS层以上的协议层,而不需要由基站经过应用服务器转发至终端设备。例如,图5为根据本申请实施例的终端设备的部分协议层的示意图,如图5所示,AS层以上的协议层可以包括非接入层(Non-access stratum,NAS)层、操作系统(operating system,OS)层和应用层中的至少一层。
这样,第一基站向终端设备发送的第一信息可以应用于终端设备的AS层以上的任意一层,例如,可以应用于终端设备的NAS层、OS层和应用层,也就是说,基站可以向终端设备的AS层以上的任意一层发送信息,而无需经过应用服务器转发,可以节省传输时间。
应理解,本申请实施例中的第一信息可以包括应用于终端设备AS层以上任意协议层中的任意信息。例如,该第一信息可以包括该第一基站对该终端设备的协议数据单元(Protocol Data Unit,PDU)会话和/或服务质量(Quality of Service,QoS)流的支持情况。
具体地,该第一信息中包括的PDU会话和/或QoS流的支持情况可以包括以下信息中的至少一个:该目标网络设备是否支持该PDU会话;该目标网络设备是否支持该QoS流;该目标网络设备是否能够保证该PDU会话的QoS参数;该目标网络设备是否能够保证该QoS流的QoS参数;该PDU会话的QoS参数中该目标网络设备能够保证的QoS参数;该QoS流的QoS参数中该目标网络设备能够保证的QoS参数允许或建议该终端设备发起接入该目标网络设备的小区的时间。
例如,该第一信息可以应用于切换场景中,其中,第二基站为终端设备的源基站,第一基站为终端设备的目标基站,终端设备执行切换流程,即需要从源基站切换至目标基站。目标基站向终端设备发送该第一信息,可以用于终端设备根据该第一信息确定是否切换至目标基站。例如,终端设备根据接收到由目标基站发送的第一信息,确定一个或者多个PDU会话或者QoS流是否能够保障QoS参数,进而确定是否切换至该目标基站。
可选的,上述以目标基站将第一信息发送至终端设备为例进行说明,或者,该目标基站也可以将第一信息发送至源基站,例如,可以通过该源基站确定第一信息中包括的目标基站对终端设备的PDU会话和/或QoS流的支持情况,从而确定是否将终端设备切换至目标基站。因此,本申请实施例提出了另一种传输信息的方法。
具体地,图6为本申请实施例提供的另一种传输信息的方法300的示意图,该方法300可以由两个基站执行。为了便于后面描述,这里将该两个基站分别称为第一基站和第二基站,该第一基站或者第二基站都可以为任意一个基站,例如,该第一基站可以为如图1所示的网络设备,而该第二基站也可以为如图1所示的网络设备。如图6所示,该方法300可以包括以下步骤。
S310,发送第一信息,即第一基站向第二基站发送第一信息。其中,具体地,该第一基站可以直接或者间接向该第二基站发送第一信息。下面将结合图6和图7详细说明。
可选的,作为一个实施例,如图6所示,该S310可以表示第一基站直接向第二基站发送第一信息。 例如,该第一基站通过Xn接口,向该第二基站发送该第一信息。
可选的,作为一个实施例,如图6所示,该S310还可以表示第一基站通过其他设备向第二基站发送第一信息。例如,第一基站可以通过核心网设备向第二基站发送第一信息。下面将结合图7举例说明,图7示出了本申请实施例的第一基站通过核心网设备向第二基站发送第一信息的示意图。
如图7所示,S310中的第一基站向第二基站发送第一信息可以包括:S311,发送第一信息,即第一基站向核心网设备发送第一信息。例如,该第一基站可以通过N2接口向核心网设备发送第一信息,并继续执行S312。
S312,转发第一信息,即核心网设备将接收到的第一基站发送的第一信息,转发至第二基站。
应理解,上述过程中,第一基站通过核心网设备向第二基站发送第一信息,其中,该第一信息可以位于容器中,以便于核心网设备将该容器中的第一信息透传至第二基站,在透传过程中,核心网设备对该容器内的内容不感知或不修改。
应理解,该方法300中的第一信息可以与方法200中的第一信息的内容相同,或者不同。例如,该方法300中的该第一信息也可以指第一基站对终端设备的PDU会话和/或QoS流的支持情况。具体地,该方法300中的第一信息可以包括以下信息中的至少一个:该目标基站是否支持该PDU会话;该目标基站是否支持该QoS流;该目标基站是否能够保证该PDU会话的QoS参数;该目标基站是否能够保证该QoS流的QoS参数;该PDU会话的QoS参数中该目标基站能够保证的QoS参数;该QoS流的QoS参数中该目标基站能够保证的QoS参数允许或建议该终端设备发起接入该目标基站的小区的时间。
对应的,在S320中,该第二基站接收第一基站发送的第一信息,并根据该第一信息确定第一基站对终端设备的PDU会话和/或QoS流的支持情况。
可选的,该方法300同样可以应用于切换场景中,并且,第二基站为终端设备的源基站,第一基站为终端设备的目标基站,终端设备执行切换流程,即需要从源基站切换至目标基站。根据该方法300,目标基站向第二基站发送该第一信息,可以用于第二基站根据该第一信息确定终端设备是否可以切换至该目标基站。例如,第二基站根据接收到由目标基站发送的第一信息,确定终端设备的一个或者多个PDU会话或者QoS流是否能够保障QoS参数,进而确定该终端设备是否切换至该目标基站。
考虑到方法300和方法200均为可以独立使用的实施例,而该方法300中的第一信息与可能包括的内容与方法200中的第一信息可能包括的内容可能包括的内容相同,并且方法300和方法200均可以应用于切换场景,所以这里将方法200和方法300中的信息均称为“第一信息”。但方法300中的第一信息与方法200中的第一信息不同,例如,二者包括的内容可能不同;同时,传输方式也不同。
应理解,根据上述方法200和方法300可知,对于切换场景,目标基站可以向源基站或者终端设备发送第一信息,以便于接收到第一信息的源基站或者终端设备根据该第一信息,确定目标基站对终端设备的PDU会话和/或QoS流的支持情况,进而确定终端设备是否可以切换至该目标基站。另外,本申请实施例还提出了一种传输信息的方法,源基站也可以向目标基站发送信息,以便于目标基站确定终端设备的是否允许不保障QoS参数和/或是否允许更改QoS流的标识。
具体地,图8为本申请实施例提供的再一种传输信息的方法400的示意图,该方法400可以由两个基站执行。为了便于后面描述,这里将该两个基站分别称为第一基站和第二基站,该第一基站或者第二基站都可以为任意一个基站,例如,该第一基站可以为如图1所示的网络设备,而该第二基站也可以为如图1所示的网络设备。如图8所示,该方法400可以包括以下步骤。
S410,发送第一信息,即第二基站向第一基站发送第二信息。其中,具体地,该第二基站可以直接或者间接向该第一基站发送第二信息。下面将结合图8和图9详细说明。
可选的,作为一个实施例,如图8所示,该S410可以表示第二基站直接向第一基站发送第二信息。例如,该第二基站通过Xn接口,向该第一基站发送该第二信息。
可选的,作为一个实施例,如图8所示,该S410还可以表示第二基站通过其他设备向第一基站发送第二信息。例如,第二基站可以通过核心网设备向第一基站发送第二信息。下面将结合图9举例说明,图9示出了本申请实施例的第二基站通过核心网设备向第一基站发送第二信息的示意图。
如图9所示,S410中的第二基站向第一基站发送第二信息可以包括:S411,发送第二信息,即第二基站向核心网设备发送第二信息。例如,该第二基站可以通过N2接口向核心网设备发送第二信息,并继续执行S412。
S412,转发第二信息,即核心网设备将接收到的第二基站发送的第二信息,转发至第一基站。
应理解,上述过程中,第二基站通过核心网设备向第一基站发送第二信息,其中,该第二信息可以位于第三容器中,以便于核心网设备将该第三容器中的第二信息透传至第一基站,在透传过程中,核心网设备对该第三容器内的内容不感知或不修改。
应理解,该方法400可以用于切换场景中,并且,第二基站为终端设备的源基站,第一基站为终端 设备的目标基站,终端设备执行切换流程,即需要从源基站切换至目标基站。根据该方法400,第二基站向第一基站发送第二信息,其中,该第二信息可以包括该终端设备是否允许不保障QoS参数和/或是否允许更改QoS流的标识,该QoS参数包括该终端设备的PDU会话的QoS参数和/或该QoS流的QoS参数。
可选的,源基站向目标基站发送的第二信息可以由核心网设备提供,如在会话建立和修改时通过QoS规则一起发送给源基站,并作为一个属性参数在切换过程中被目标基站所应用和保存。
在S420中,第一基站接收到第二基站发送的第二信息,并根据该第二信息,确定终端设备的QoS参数。例如,目标基站接收到源基站发送的第二信息,在该第二信息中包括终端设备的一个或者多个QoS流是否允许不保证其QoS参数,则该目标基站根据第二信息,设置其中的QoS流的QoS参数。例如,对于某个QoS流,若该QoS流允许不保证其QoS参数,则目标基站可以将该QoS流设置为不满足其QoS参数。
应理解,本申请实施例中的QoS参数可以包括以下至少一个:时延、保证比特速率(Guaranteed Bit Rate,GBR)(或者也可以称为保证流比特速率(Guaranteed Flow Bit Rate,GFBR))和最大比特速率(Maximum Bit Rate,MBR)。并且,在不同信息中,QoS参数可能不同,同一个信息中不同PDU会话或者不同QoS流的QoS参数也可能不同。例如,上述方法200中的第一信息中的QoS参数可以包括时延,而上述方法300中的第一信息中的QoS参数可以为GBR。再例如,上述方法400中的第二信息中可能包括某个PUD会话的QoS参数,该QoS参数为时延,而该第二信息中可能还包括某个QoS流的QoS参数,该QoS参数为MBR,但本申请实施例并不限于此。
应理解,本申请实施例中的上述方法200、方法300和方法400可以分别单独使用,或者也可以互相结合使用,并且,在结合使用时,并不限制各个实施例的执行顺序,本申请实施例并不限于此。例如,方法200和方法300可以共同使用,并且可以先完成方法200再执行方法300,或者先完成方法300再执行方法200,或者也可以将方法200和方法300同时执行。再例如,还可以将上述方法200、方法300和方法400全部结合使用,比如,先执行方法400,再同时执行方法200和方法300。
应理解,上述方法200、方法300和方法400均以切换场景为例进行说明,另外,上述各个方法还可以应用于其他场景。例如,上述各个方法还可以应用于车联网(vehicle to everything,V2X)、超高可靠低时延(“Ultra Reliable Low Latency Communications,URLLC)以及无人机等对于QoS要求较高的业务。
考虑到上述方法200、方法300和方法400均可以用于切换场景,下面将结合图10和图11所示的切换场景,通过举例进行详细描述。
对于终端设备从源基站向目标基站的切换(Handover,HO)流程,大致可以分为切换准备(Handover Preparation)、切换执行(Handover Execution)和切换完成(Handover Completion)三个阶段。其中,在切换准备阶段,源基站通常会将PDU会话标识(ID)、QoS流(Flow)的ID以及相应的QoS参数告诉给目标基站,并且由目标基站决定是否能够满足数据流对应的QoS参数。
若对于某个特定的QoS Flow,目标基站不能满足其QoS参数,那么目标基站可能会拒绝对应的QoS Flow ID;或者,目标基站也可能接受该QoS Flow ID,但是不满足其QoS参数要求;或者,目标基站也可能为该QoS Flow中的数据改变到一个低的QoS参数对应的Flow上。
但是对于终端设备而言,并不知道该QoS Flow的QoS参数无法保障,这可能会导致UE不能及时停止发送/接收相应的数据或采取其他措施。因此,本申请实施例提出了用于切换过程中的传输信息的方法,下面将结合图10和图11所示的切换场景,对本申请实施例的用于切换过程中的传输信息的方法进行详细描述。
具体的,图10示出了根据本申请实施例的一种用于切换过程中的传输信息的方法500的示意图。应理解,图10仅示出了切换过程中的部分流程,并非全部流程,本申请实施例并不限于此。
如图10所示,方法500示出的切换流程为基于Xn接口的切换流程,该方法500可以包括以下步骤。
S510,传输测量控制和报告。具体地,该步骤中可以包括:源基站配置UE进行测量上报;终端设备向源基站报告测量结果,以便于源基站基于该测量结果确定该终端设备是否需要切换至目标基站。
S520,确定切换。源基站根据终端设备发送的测量报告决定执行切换。
S530,发送切换请求(HO Request)消息。源基站确定终端设备进行切换,则可以向目标基站发送HO Request消息。为了便于与其它方法货实施例区别,这里也可以将该方法500中的HO Request消息称为第一HO Request消息。
具体地,源基站可以通过Xn接口向目标基站发送HO Request消息,该HO Request消息可以包括第二信息。例如,该第二信息可以为上述方法400中的第二信息,该第二信息由目标基站读取,为了简洁,在此不再赘述。
例如,该第二信息可以包括:对于特定的PDU会话和/或QoS Flow是否允许执行“软加入(Soft Admission)”,例如,对于某个PDU会话和/或QoS Flow是否允许不保障其QoS参数,或者,是否接受 其QoS Flow ID但是不保障其QoS参数。
应理解,该第二信息可以位于该HO Request消息中的任意的一个或者多个位置。例如,可以将该第二信息直接设置在该HO Request消息中,没有二级参数。又例如,该HO Request消息中可以包括将要设置的PDU会话资源列表(PDU Session Resources To Be Setup List),可以在该PDU Session Resources To Be Setup List中包括第二信息。进一步的,在该PDU Session Resources To Be Setup List中还可以包括将要设置的PDU会话资源项目(PDU Session Resources To Be Setup Item)和/或将要设置的QoS Flows列表(QoS Flows To Be Setup List),则该第二信息可以设置在PDU Session Resources To Be Setup Item和/或QoS Flows To Be Setup List中,但本申请实施例并不限于此。
可选的,该源基站向目标基站发送的第二信息可以由核心网设备提供,如在会话建立和修改时通过QoS规则一起发送给源基站,并作为一个属性参数在切换过程中被目标基站所应用和保存。
另外,该HO Request消息还可以包括其他用于切换过程中的信息,在此不再一一列举。例如,该HO Request消息中可以包括RRC容器(Container),RRC Container包括目标基站为准备HO而必须的信息,例如,该RRC Container中至少包括以下信息中的至少一个:目标小区ID、源基站给终端设备分配的小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)、终端设备的连接非激活状态(Inactive)时间、AS层基本配置(如天线信息、下行载波频率等)、源基站上的QoS Flow与数据无线承载(data radio bearer,DRB)的映射关系以及源基站上的最小系统信息,此外,还可以包括终端设备上报的测量信息,例如,波束相关信息等。
S540,接入控制。即目标基站执行接入控制,具体可以包括:目标基站对发来的QoS Flow和/或DRB建立是否接受,还可以包括,目标基站根据第二信息,确定终端设备的PDU会话和/或QoS Flow的QoS参数。
例如,目标基站对于第二信息指示的某个PDU会话和/或QoS Flow,目标基站在不能满足其QoS参数时,可以拒绝该QoS参数,或者目标基站也可以接受该QoS Flow ID,但是不满足其QoS参数要求;或者,目标基站也可以为该QoS Flow中的数据改变到一个低的QoS参数对应的Flow上。
S550,发送切换请求回复消息。即目标基站同意切换请求后,目标基站贮备层1/层2的相关资源,还会向源基站发送切换请求回复消息,例如,目标基站通过Xn接口向源基站发送切换请求回复消息,或者也可以称为切换请求确认(Handover Request Acknowledge)消息。为了便于与其他实施例或者方法区分,这里也可以将该方法500中的Handover Request消息称为第一Handover Request Acknowledge消息。
具体地,该Handover Request Acknowledge中可以包括第一信息,该第一信息可以为方法200和/或方法300中的第一信息,为了简洁,在此不再赘述。

应理解,该第一信息可以位于该Handover Request Acknowledge消息中的任意一个或者多个位置。例如,该第一信息可以直接位于该Handover Request Acknowledge中,无二级参数,以便于源基站接收该Handover Request Acknowledge消息,并读取其中的第一信息。

应理解,上述S510至550均属于切换准备阶段,另外,切换准备阶段还可能包括其他步骤,本申请实施例并不限于此。
S560,发送切换命令。即源基站向终端设备发送切换命令(HO commend),该HO commend可以用于指示终端设备切换至目标基站。
应理解,传统的切换流程中,源基站只会在终端设备上报测量并达到切换门限时才会触发切换准备流程。但是为了加速切换的速度以及切换的准确性,例如,选择最合适的目标基站,现在的3GPP有如下增强的条件切换(Conditional Handover):“切换准备”阶段会提前进行;源基站会向多个目标基站执行“切换准备”中的切换请求,并根据不同目标基站的回复信息(如是否支持重要业务的传输等)决定选择哪一个或几个目标基站供UE执行切换使用。
例如,情况一,源基站将选择好的一个或多个目标基站,通过Handover Command消息发送给终端设备,终端设备在执行切换过程时,自行决定切换到哪个一个目标基站。
又例如,情况二,源基站为UE选择好切换的一个或多个目标基站,然后通过Handover Command消息发送给UE,UE严格根据源基站发送的目标基站列表接入到指定的基站。
可选的,对于目标基站向源基站发送的包括Transparent Container的Handover Request Acknowledge消息,源基站可以通过该HO commend将Transparent Container透传至终端设备。其中,该Transparent Container中可以包括第一信息,即该第一信息可以通过Transparent Container透传至终端设备,此时该第一信息对应上述方法200中的第一信息的传输。同时,该第一信息可以应用于上述的情况一,以便于终端设备根据该第一信息,确定是否切换至目标基站,或者,该终端设备什么时间可以切换至该目标基站。

其中,若该源基站通过HO commend转发该第一信息至终端设备,则该第一信息仍然可以对应上述方法200中的第一信息的传输,并且,该第一信息可以应用于上述的情况一,以便于终端设备根据该第一信息,确定是否切换至目标基站。
或者,该源基站还可以读取该Handover Request Acknowledge消息中的第一信息,该第一信息对应于上述方法300中的第一信息的传输,同时,该第一信息可以应用于上述情况二,以便于由源基站确定该终端设备是否切换至目标基站,或者,该终端设备什么时间可以切换至该目标基站,而不需要将该第一信息转发至终端设备。
可选的,该HO commend中还可以包括其他用于切换的信息,本申请实施例并不限于此。例如,该HO commend中还可以包括需要介入目标小区的消息,例如,可以包括:目标小区(Cell)的ID,新的C-RNTI,目标基站的安全算法标识,专有RACH资源,随机接入信道(Random Access Channel,RACH)资源和同步信号块(Synchronization Signal Block,SS Block)的关联关系,RACH资源和终端设备特定的信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS)配置的关联关系,普通无线接入网(Radio Access Network,RAN)资源以及目标小区系统信息块(System Information Blocks,SIB)信息等。

应理解,步骤S560和S570属于切换执行阶段,另外,切换执行阶段还可能包括其他步骤,本申请实施例并不限于此。
例如,该切换执行阶段还可能包括:序列号(Sequence Number,SH)状态传递(SN STATUS TRANSFER)。具体地,终端设备向目标基站发起随机接入流程的同时,源基站可以发送SN STATUS TRANSFER给目标基站,用于告知目标基站上行分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)SN接收状态以及下行PDCP SN发送状态。
可选的,该方法500还可以包括:S580,路径转移(Path Switch)。在完成切换后,目标基站会向核心网设备发送通知消息,以便于核心网设备更换数据发送的路径。
该阶段的信令用于告诉核心网设备空口切换已完成,核心网将数据的发送路径由源基站改变到目标基站。
应理解,步骤S580属于切换完成阶段,另外,该切换完成阶段还可以包括其他步骤,本申请实施例并不限于此。
例如,在路径切换完成之后,目标基站会指示源基站释放终端设备的上下文,切换完成。
可选的,图11示出了根据本申请实施例的另一种用于切换过程中的传输信息的方法600的示意图。应理解,图11仅示出了切换过程中的部分流程,并非全部流程,本申请实施例并不限于此。
如图11所示,方法600示出的切换流程为基于N2接口的切换流程,该方法600可以包括以下步骤。
S610,发送切换要求消息。具体地,源基站向核心网设备发送切换要求(Handover Required)消息,例如,源基站通过N2接口核心网设备发送Handover Required消息,该Handover Required消息用于请求将终端设备切换至目标基站。
可选的,该Handover Required消息中可以包括第二信息,例如,该第二信息可以为上述方法400中的第二信息,并且该第二信息的传输可以适用于上述方法400中的第二信息的传输过程,为了简洁,在此不再赘述。
例如,该第二信息可以包括:对于特定的PDU会话和/或QoS Flow是否允许执行“软加入(Soft Admission)”,例如,对于某个PDU会话和/或QoS Flow是否允许不保障其QoS参数,或者,是否接受其QoS Flow ID但是不保障其QoS参数。
应理解,该第二信息可以位于该Handover Required消息中的任意的一个或者多个位置。例如,可以将该第二信息直接设置在该Handover Required消息中,没有二级参数,此时,该核心网设备可以读取该第二信息,并再由该核心网设备转发至目标基站。
又例如,该Handover Required消息中可以包括PDU会话资源列表(PDU Session Resources Item),该第二信息可以位于该PDU Session Resources Item中;或者,该Handover Required消息中可以Handover Required转移(Transfer)参数,该第二信息可以位于该Handover Required Transfer参数中。此时,该第二信息也可以由核心网设备读取,并再由该核心网设备转发至目标基站。
又例如,该第二信息还可以位于容器中,或者还可以称为透明容器(Transparent Container),或者还可以称为源到目标透明容器(Source to Target Transparent Container)。该Handover Required消息中包括该容器,该容器中包括第二信息,以便于核心网将该容器透传至目标基站,而该核心网设备对该容器内的内容不感知或不修改或不读取。
可选的,该Handover Required消息中还可以包括其他用于切换的信息,本申请实施例并不限于此。
S620,发送切换请求(Handover Request)消息。即核心网设备向目标基站发送Handover Request消息,以请求将终端设备切换至目标基站。为了便于与其它方法区别,这里也可以将该方法600中的Handover Request消息称为第二Handover Request消息。
具体的,该Handover Request中可以包括第二信息。与步骤S620相对应,该第二信息也为上述方法400中的第二信息。
例如,该核心网设备可以读取处第二信息,再将该第二信息转发至目标基站。又例如,该第二信息可以位于容器中,则该核心网设备可以将该容器透传至目标基站。
可选的,该Handover Request消息中还可以包括其他用于切换的信息,本申请实施例并不限于此。
S630,发送切换请求回复消息。即目标基站确定可以切换之后,可以向核心网设备发送切换请求回复消息,例如,目标基站通过N2接口向核心网设备发送切换请求回复消息,或者也可以称为切换请求确认(Handover Request Acknowledge)消息。为了便于与其他实施例或者方法区分,这里也可以将该方法630中的Handover Request Acknowledge消息称为第二Handover Request Acknowledge消息。
具体地,该Handover Request Acknowledge中可以包括第一信息,该第一信息可以为方法200和/或方法300中的第一信息,为了简洁,在此不再赘述。
例如,该第一信息可以包括以下内容中的至少一个:特定的PDU会话和/或QoS Flow不能建立,特定的PDU会话和/或QoS Flow的QoS参数不能保障,特定的PDU会话和/或QoS Flow的哪些QoS参数不能保障(如GFBR不能保障),以及该目标基站允许或建议终端设备发起接入目标基站小区的时间信息。
应理解,该第一信息可以位于该Handover Request Acknowledge消息中的任意一个或者多个位置。例如,该第一信息可以直接位于该Handover Request Acknowledge中,无二级参数。此时,该核心网设备可以读取该第一信息,并将该第一信息转发至源基站,以便于源基站进一步处理,例如,该源基站可以转发或者不转发该第一信息。
又例如,该第一信息还可以位于该Handover Request Acknowledge消息中的PDU Session Resource Admitted Item中,此时,该核心网设备也可以读取该第一信息,并将该第一信息转发至源基站,以便于源基站进一步处理,例如,该源基站可以转发或者不转发该第一信息。
再例如,该第一信息还可以位于容器中,例如,还可以称为透明容器(Transparent Container),或者,也可以称为Target to Source Transparent Container。核心网设备可以将该包括第一信息的容器透传至源基站,即核心网设备不感知或不修改或不读取该容器内的内容,以便于源基站进一步处理,例如,该源基站还可以将该容器继续透传给终端设备,或者,该源基站还可以读取该容器内容。
另外,该Handover Request Acknowledge消息中还可以包括其他用于切换过程的信息;或者,该Handover Request Acknowledge消息中的容器也还可以包括其他信息,本申请实施例并不限于此。
应理解,上述S610至S630均属于切换准备阶段,另外,切换准备阶段还可能包括其他步骤,本申请实施例并不限于此。例如,该切换准备阶段,该核心网设备可以与目标基站交互确认能够切换的承载,并且核心网设备还可以建立与目标基站相关的PDU会话。
S640,发送第一切换命令。即核心网设备向源基站发送第一切换命令(HO Command),该第一HO commend可以用于指示终端设备可以切换至目标基站。
应理解,对应于上述步骤S630,该第一HO commend中包括第一信息。
例如,该核心网设备可以将第一信息设置在该第一HO commend中的任意一个或者多个位置。例如,该第一HO commend可以直接包括第一信息,无二级参数;或者,该第一HO commend还可以包括其他参数信息,在该其他参数信息中包括该第一信息。此时,源基站可以读取该第一信息,以便于该源基站进一步处理,例如,该源基站可以转发或者不转发该第一信息。
又例如,该第一HO commend中还可以包括容器,第一信息位于该容器中,例如,还可以称为透明容器(Transparent Container),或者,也可以称为Target to Source Transparent Container。源基站可以将包括第一信息的容器透传至终端设备,即该源基站不感知或不修改或不读取该容器内的内容;或者,该源基站还可以读取该容器中的内容,以便于源基站进一步处理,例如,该源基站还可以转发或者不转发该第一信息。
S650,发送第二切换命令。即源基站向终端设备发送第二HO commend,为了与上述S640中的HO commend区别,这里称为第二HO commend。,该第二HO commend可以用于指示终端设备切换至目标基站。
应理解,与方法500中的S560类似,若存在多个目标基站,方法600中源基站向终端设备发送第二HO commend也可以分为两种情况。情况一,源基站将选择好的一个或多个目标基站,通过Handover Command消息发送给终端设备,终端设备在执行切换过程时,自行决定切换到哪个一个目标基站。情况二,源基站为UE选择好切换的一个或多个目标基站,然后通过Handover Command消息发送给UE,UE严格根据源基站发送的目标基站列表接入到由源基站指定的目标基站。
因此,对于源基站接收到的第一信息,该源基站可以将该第一信息转发至终端设备,即对应于上述情况一,以便于终端设备可以根据该第一信息,确定是否切换至目标基站,或者,确定什么时间可以切换至该目标基站。或者,该源基站也可以不转发该第一信息至终端设备,即可以对应于上述情况二,则源基站可以根据该第一信息确定该终端设备是否切换至目标基站,或者,确定该终端设备什么时间可以切换至该目标基站。
具体的,对于源基站将该第一信息转发至终端设备的情况,该第二HO commend中可以包括容器,该容器中包括第一信息,该源基站将该容器通过第二HO commend透传至终端设备,该源基站不感知或不修改或不读取该容器;或者,该第一信息还可以位于该第二HO commend中的其他位置,由该源基站在第一HO commend中读取后再转发至该终端设备。终端设备根据接收到的第二HO commend中的第一信息,确定是否切换至目标基站,或者,确定什么时间可以切换至该目标基站。
而对于源基站不转发该第一信息的情况,该源基站可以通过接收的第一HO commend读取第一信息,该源基站根据该第一信息,确定终端设备是否切换至目标基站,或者,该终端设备什么时间可以切换至该目标基站。
可选的,该HO commend中还可以包括其他用于切换的信息,本申请实施例并不限于此。
S660,执行空口切换。终端设备接收源基站发送的第二HO commend,触发UE向目标基站执行空口切换流。
应理解,上述S640至S660均属于切换执行阶段,另外,切换执行阶段还可能包括其他步骤,本申请实施例并不限于此。例如,在终端设备空口切换完成后,终端设备可以向目标基站发送消息,例如,发送切换确认(Handover Confirm)消息。
S670,更新会话以及路径转移。目标基站与核心网设备交互来更新目标侧会话以及转换数据传输路径。
可选的,该方法600还可以包括:应理解,步骤S670属于切换完成阶段,另外,该切换完成阶段还可以包括其他步骤,本申请实施例并不限于此。
因此,本申请实施例的应用切换过程中的传输信息的方法,源基站在发送切换请求或者切换要求时,可以告知目标基站是否允许不保障QoS,也就是源基站有权向目标基站申请是否执行“Soft Admission”行为,从而保证QoS参数。另外,源基站在发送切换命令时,还可以告知终端设备目标基站是否可以保障QoS,或告知终端设备在指定时间进行切换时可以保障QoS参数,这样可以充分利用现有消息和机制完成对于终端设备和基站的通知行为,并且对于QoS参数无法保障的情况,能够给予终端设备足够的消息和决 定权,终端设备可以主动选择切换而放弃QoS参数的保障,或者选择不切换而维持QoS保障。
PRA是核心网用于感知终端设备位置的一种区域信息,用一个或多个跟踪区(Tracking Area,TA)、基站ID和/或小区ID来描述,由于切换基站时会更换终端设备对应的TA、基站ID和/或小区ID,这些改变会上报给核心网设备,例如上报给AMF,AMF很容易根据PRA的配置来判断该终端设备是否进入或离开了一定的区域,然后通知给其他网元,如策略网元,即策略控制功能(Policy Control function,PCF)。
RAN通知区域(RAN Notification Area,RNA)是终端设备处于RRC Inactive状态时的一种区域定义,用一个或多个TA或RAN区域节点(area code)来描述。RRC Inactive是终端设备的一种状态,即终端设备的RRC连接(终端设备与基站的控制面连接)被释放,但基站与核心网的连接仍然保持。这样一来,核心网设备AMF在RRC Inactive状态下始终认为终端设备是处于连接管理(connection management,CM)连接(Connected)状态,但其实终端设备与基站之间的连接是断开的。为了对RRC Inactive状态进行管理,终端设备在RNA规定的范围内可以断开RRC连接并且基站不告知核心网侧,同时终端设备在RNA区域内移动时可以不告知基站,当终端设备离开所划定的RNA时,终端设备会触发RNA更新(Update)流程,告知基站其当前的连接的基站位置。此外,类似TA Update,终端设备在RNA范围内也会周期性执行RNA Update,以让基站知道UE是可达的。
但是,如图12所示,如果PRA的配置(或者说划分)和RNA的配置(或者划分)是重叠的状态,也就是RNA区域跨越了PRA的边界,或者RNA的区域跨越了PRA的边界,那么处于RRC Inactive状态的终端设备在走出或进入PRA时,基站是无法感知到的,从而AMF也无法知道其是否进入或离开了PRA。因此,本申请实施例提出了两种解决方式。
方式一,将RNA和PRA设置为:RNA的区域不能跨越PRA的边界,或者说,PRA的区域不能跨域RNA的边界。也就是说,RNA设置为PRA的子集,即PRA包括RNA的区域的全都,例如,一个PRA区域中可以包括一个或者多个RNA,如图13所示,这里以一个一个PRA区域中包括3个RNA为例。相反的,PRA也可以设置为RNA的子集,即RNA包括PRA的区域的全都,例如,一个RNA区域包括一个或者多个PRA。
例如,本申请实施例提供了一种确定终端设备位置的方法。具体地,图14示出了根据本申请实施例的确定终端设备位置的方法700的示意图,如图14所示,该方法700包括:核心网设备确定终端设备是否进入或离开PRA,该终端设备处于RRC连接非激活状态并且位于RNA,该PRA不跨越该RNA的边界,也就是说,该RNA也不会不跨越该PRA的边界。
方式二,对于存在图12所示的情况,PRA与RNA不同时使用。具体地,在核心网设备使用PRA事件触发功能时,终端设备不能使用RRC Inactive功能;或者,终端设备使用RRC Inactive功能时,核心网设备不使用PRA事件触发功能。
通过上述两种方式,可以避免RRC Inactive状态的终端设备在走出或进入PRA时,基站是无法感知到的情况,也就可以避免AMF无法知道其是否进入或离开了PRA的情况。
应理解,在本申请的各种实施例中,上述各过程的序号的大小并不意味着执行顺序的先后,各过程的执行顺序应以其功能和内在逻辑确定,而不应对本申请实施例的实施过程构成任何限定。
另外,本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
