下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的一种通信方法、装置及设备进行详细地说明。
请参见图2,图2是本申请实施例提供的一种通信方法的流程图,如图2所示,包括如下步骤:
步骤201、终端接收第n代移动通信网络的第一网络侧设备发送的第一消息,所述第一消息用于如下至少一项:指示测量第n-2代移动通信网络的小区、指示接入第n-2代移动通信网络,其中,n为大于或等于6的整数。
在一些实施方式中,上述第n代移动通信网络可以是第6代(6th Generation,6G)移动通信网络(简称6G网络),上述第n-2代移动通信网络则为第4代(4th Generation,4G)移动通信网络(简称4G网络),对此不作限定,例如:上述第n代移动通信网络可以是第7代(7th Generation,7G)移动通信网络(简称7G网络),上述第n-2代移动通信网络则为第5代(5th Generation,5G)移动通信网络(简称5G网络)。
其中,上述第一网络侧设备可以是接入网设备,如6G基站。
上述终端接收第n代移动通信网络的第一网络侧设备发送的第一消息可以是终端在接入第n代移动通信网络后接收上述第一消息。或者,第n代移动通信网络不支持多媒体业务,或者第n代移动通信网络不支持回退到第n-1代移动通信网络进行多媒体业务的情况下接收上述第一消息。
上述多媒体业务可以是用于传输多媒体信息的业务,例如:用于传输语音、视频等数据的业务,如语音通话,或IP多媒体系统(IP Multimedia Subsystem,IMS)业务。
例如:以6G为例,在6G部署初期,6G网络无法支持6G承载语音(Voice over 6G,Vo6G)(或者无法直接在6G进行语音通话,或者,无法直接在6G进行语音数据的传输),在终端有相应需求的情况下,第一网络侧设备向终端发送上述第一消息;又例如:终端在6G建立多媒体会话的情况下,第一网络侧设备向终端发送上述第一消息。
上述多媒体会话用于传输多媒体业务,如用于传输IMS业务。
本申请实施例中,多媒体会话也可以称作协议数据单元(Protocol Data Unit,PDU)会话(session),如用于传输IMS业务的PDU会话后续简称IMS PDU会话;或多媒体会话也可以称作分组数据网络(Packet Data Network,PDN)连接(connection)或者多媒体连接等名称,本申请实施例中对多媒体会话的名称不作限定。
步骤202、所述终端响应所述第一消息。
上述响应所述第一消息可以包括如下至少一项:
测量第n-2代移动通信网络的小区;
获取第n-2代移动通信网络的网络侧设备为终端分配的信息;
接入第n-2代移动通信网络。
在本申请实施例中,由于第一消息用于指示测量第n-2代移动通信网络的小区、指示接入第n-2代移动通信网络,从而使得终端支持从第n代移动通信网络接入或者退回到第n-2代移动通信网络,从而提高终端的业务性能。
需要说明的是,从第n代移动通信网络接入到第n-2代移动通信网络也可以理解或替换为从第n代移动通信网络重选或重定向到第n-2代移动通信网络。
例如:以6G为例,在6G部署初期,6G网络无法支持Vo6G(或者无法直接在6G进行语音通话或者无法直接在6G进行语音数据的传输),终端响应上述第一消息回退到4G网络进行语音通话。
另外,由于是指示测量第n-2代移动通信网络的小区、指示接入第n-2代移动通信网络,这样可以避免运营商不支持第n-1代移动通信网络的多媒体业务或者第n-1代移动通信网络不支持多媒体业务的情况下,终端从第n代移动通信网络回退到第n-1代移动通信网络,再从第n-1代移动通信网络退回到第n-2代移动通信网络,即避免终端进行两次回退,以提升终端的业务效率,以及节约终端和网络侧设备的开销。
例如:以6G为例,在6G部署初期,6G网络无法支持Vo6G(或者无法直接在6G进行语音通话),若该运营商同样不支持新空口承载语音(Voice over New Radio,VoNR),这样可以避免终端从6G回退到5G,再从5G退回到4G。
作为一种可选的实施方式,在所述第一消息指示测量第n-2代移动通信网络的小区的情况下,所述终端响应所述第一消息,包括:
所述终端接收第二消息,所述第二消息包括所述第n-2代移动通信网络的第二网络侧设备为所述终端配置的信息;
所述终端基于所述信息接入所述第二网络侧设备。
其中,上述第二网络侧设备可以是接入网设备,如4G基站。
上述为所述终端配置的信息可以包括为终端配置的无线资源(radio resource)信息,或者其他用于业务传输的信息,对此不作限定。
上述终端基于所述信息接入所述第二网络侧设备可以理解为终端通过切换的方式接入第二网络侧设备,即通过切换的方式接入第n-2代移动通信网络,其中,接入第n-2代移动通信网络也可以理解为回退到第n-2代移动通信网络。例如:以6G为例,在6G部署初期,6G网络无法支持Vo6G(或者无法直接在6G进行语音通话),终端通过切换的方式回退到4G。
该实施方式中,可以实现基于上述信息接入第二网络侧设备,即实现接入第n-2代移动通信网络,从而可以基于第n-2代移动通信网络进行业务传输,如通过第n-2代移动通信网络进行语音通话,以提高终端的业务性能。
在一些实施方式中,在接收上述第二消息之前,终端还可以测量第n-2代移动通信网络的小区,并向第n-2代移动通信网络的第二网络侧设备发送测量报告,从而使得第二网络侧设备为终端配置的信息与终端的测量报告匹配,以提高终端的业务性能。
在一些实施方式中,也可以不发送测量报告,直接接收上述第二消息。
作为一种可选的实施方式,在所述第一消息指示接入第n-2代移动通信网络的情况下,所述终端响应所述第一消息,包括:
所述终端向所述第n-2代移动通信网络的第一核心网设备发送移动性更新请求;
所述终端接收所述第一核心网设备发送的所述移动性更新请求的响应。
其中,上述第一核心网设备可以是MME或AMF等核心网设备。
上述移动性更新请求可以是跟踪区更新(Tracking Area Update,TAU),或者移动性注册更新(mobility register update,MRU)等,对此不作限定。
上述移动性更新请求的响应可以是TAU接受消息,或者MRU接受消息等。
该实施方式中,由于发起移动性更新,这样可以实现通过重定向或重选的方式接入或退回到第n-2代移动通信网络,从而可以基于第n-2代移动通信网络进行业务传输,如通过第n-2代移动通信网络进行语音通话,以提高终端的业务性能。例如:以6G为例,在6G部署初期,6G网络无法支持Vo6G(或者无法直接在6G进行语音通话),终端通过重定向的方式回退到4G。
可选地,所述移动性更新请求包括如下至少一项:
第一终端标识,所述第一终端标识为所述终端在所述第n-2代移动通信网络中的标识,且所述第一终端标识是根据所述终端在所述第n代移动通信网络的第二终端标识映射得到;
第一指示信息,所述第一指示信息用于指示如下至少一项:所述终端是从所述第n代移动通信网络移动到所述第n-2代移动通信网络,选择第n-1代移动通信网络的核心网设备(5G AMF);
第三终端标识,所述第三终端标识为所述终端在所述第n-1代移动通信网络中的标识。
上述第一终端标识可以是全球唯一临时UE标识(Globally Unique Temporary UE Identity,GUTI),或者移动终端设备永久标识(Permanent Equipment Identifier,PEI)等终端标识。
上述第二终端标识为可以是GUTI或PEI等终端标识。
上述根据所述终端在所述第n代移动通信网络的第二终端标识映射得到可以是基于第一终端标识和第二终端标识的映射关系映射得到,具体可以是由上述终端进行映射得到,或者由网络侧设备映射得到再发送给终端。
由于上述第一终端标识是根据所述终端在所述第n代移动通信网络的第二终端标识映射得到,这样可以实现网络侧设备基于第一终端标识可以确定第n代移动通信网络的网络侧设备的信息,以向第n代移动通信网络的网络侧设备请求终端的上下文,以使得第n-2代移动通信网络的网络侧设备基于该上下文向终端发送移动性更新请求的响应,以实现终端接入第n-2代移动通信网络。
上述终端是从所述第n代移动通信网络移动到所述第n-2代移动通信网络可以是终端是从所述第n代移动通信网络重选或切换到所述第n-2代移动通信网络。
由于上述第一指示信息指示终端是从所述第n代移动通信网络移动到所述第n-2代移动通信网络,从而使得第n-2代移动通信网络的网络侧设备执行相关的操作,以实现终端接入第n-2代移动通信网络。
由于上述第一指示信息指示选择第n-1代移动通信网络的核心网设备,从而使得第n-2代移动通信网络的网络侧设备基于第n-1代移动通信网络的核心网设备获取终端的上下文,基于该上下文向终端移动性更新请求的响应,以实现终端接入第n-2代移动通信网络。
例如:终端在步骤5的移动性更新请求携带上述第一指示信息和第一终端标识(如GUTI-1),第一终端标识是UE根据第二终端标识(如6G GUTI)映射(map)得到的4G GUTI,第n-2代移动通信网络的第一核心网设备(如MME)根据第一指示信息确定向第n-1代移动通信网络的核心网设备(如5G AMF)发送请求,第n-1代移动通信网络的核心网设备(如5G AMF)据第一终端标识(如GUTI-1)确定第n代移动通信网络的核心网设备(如6G AMF)的地址,并向第n代移动通信网络的核心网设备(如6G AMF)发送上下文请求,第n代移动通信网络的核心网设备(如6G AMF)之后向第n-1代移动通信网络的核心网设备(如5GAMF)发送终端的上下文,如PDN连接上下文(PDN connection context),第n-1代移动通信网络的核心网设备(如5G AMF)将该上下文发送给第n-2代移动通信网络的第一核心网设备(如MME)。
需要说明的是,上述举例是以6G AMF与MME无法直接通信,需要5G AMF中转为例进行介绍的。
上述第三终端标识为可以是GUTI或PEI等终端标识。
由于包括上述第三终端标识,从而使得第n-2代移动通信网络的网络侧设备基于第三终端标识确定第n-1代移动通信网络的核心网设备,以通过第n-1代移动通信网络的核心网设备获取终端的上下文,基于该上下文向终端发送移动性更新请求的响应,以实现终端接入第n-2代移动通信网络。
例如:终端在移动性更新请求包含第三终端标识(如GUTI-2),第n-2代移动通信网络的第一核心网设备(如MME)根据该第三终端标识(如GUTI-2)确定第n-1代移动通信网络的核心网设备(如5G AMF),第三终端标识(如GUTI-2)可以是第n-1代移动通信网络的核心网设备(如5G AMF)为终端分配的5G GUTI,即上述GUTI-2;
终端在6G进行注册或移动性更新过程中,第n代移动通信网络的核心网设备(如6GAMF)向第n-1代移动通信网络的核心网设备(如5G AMF)发送请求消息,该请求消息用于请求为终端分配第三终端标识(如5G GUTI),在该请求消息中包含第二终端标识(6GGUTI);
第n-1代移动通信网络的核心网设备(如5G AMF)向第n代移动通信网络的核心网设备(如6G AMF)发送第三终端标识(如5G GUTI),并保存第二终端标识(6G GUTI)和第三终端标识(如5G GUTI)的对应关系;
第n代移动通信网络的核心网设备(如6G AMF)在注册或移动性更新响应消息中向终端提供第三终端标识(如5G GUTI);
第n-2代移动通信网络的第一核心网设备(如MME)向第n-1代移动通信网络的核心网设备(如5G AMF)请求终端的上下文时,携带第三终端标识(如5G GUTI),第n-1代移动通信网络的核心网设备(如5G AMF)根据保存的对应关系和第三终端标识(如5GGUTI),获得第二终端标识(6G GUTI),并根据第二终端标识(6G GUTI)确定第n代移动通信网络的核心网设备(如6G AMF),向第n代移动通信网络的核心网设备(如6G AMF)发送上下文请求,第n代移动通信网络的核心网设备(如6G AMF)之后向第n-1代移动通信网络的核心网设备(如5G AMF)发送终端的上下文,如PDN连接上下文(PDN connection context),第n-1代移动通信网络的核心网设备(如5G AMF)将该上下文发送给第n-2代移动通信网络的第一核心网设备(如MME)。
需要说明的是,上述举例是以6G AMF与MME无法直接通信,需要5G AMF中转为例进行介绍的。
又例如:终端在步骤5的移动性更新请求中包含第一终端标识(如GUTI-1)和第三终端标识(如GUTI-2)。
其中,第三终端标识(如GUTI-2)的获得方法为:
终端在6G进行注册或移动性更新过程中,第n代移动通信网络的核心网设备(如6GAMF)向第n-1代移动通信网络的核心网设备(如5G AMF)发送请求消息,该请求消息用于请求为终端分配第三终端标识(如5G GUTI,即上述GUTI-2);
第n-1代移动通信网络的核心网设备(如5G AMF)向第n代移动通信网络的核心网设备(如6G AMF)发送第三终端标识(如5G GUTI);
第n代移动通信网络的核心网设备(如6G AMF)在注册或移动性更新响应消息中向终端提供第三终端标识(如5G GUTI);
第n-2代移动通信网络的第一核心网设备(如MME)根据第三终端标识确定第n-1代移动通信网络的核心网设备(如5G AMF),第n-1代移动通信网络的核心网设备(如5GAMF)根据第n-2代移动通信网络的第一核心网设备(如MME)发送的第一终端标识(如GUTI-1)确定第n代移动通信网络的核心网设备(如6G AMF)向第n代移动通信网络的核心网设备(如6G AMF)发送上下文请求,第n代移动通信网络的核心网设备(如6G AMF)之后向第n-1代移动通信网络的核心网设备(如5G AMF)发送终端的上下文,如PDN连接上下文(PDN connection context),第n-1代移动通信网络的核心网设备(如5G AMF)将该上下文发送给第n-2代移动通信网络的第一核心网设备(如MME)。
需要说明的是,这里的第n-1代移动通信网络的核心网设备(如5G AMF)可以是一个专用网元,专门用于第n代移动通信网络向第n-2代移动通信网络交互(interworking)时使用的网元。
可选地,所述方法还包括:
所述终端向所述第一网络侧设备(6G基站)发送所述第n-2代移动通信网络的测量报告,所述测量报告包括所述第n-2代移动通信网络的小区信息。
上述小区信息可以包括目标网络侧设备的标识(target eNB ID)、目标跟踪区域标识(Tracking Area Identity,TAI),即target TAI。
该实施方式中,由于向第一网络侧设备发送上述测量报告,从而可以使得第一网络侧设备可以基于该测量报告向终端发送上述第一消息,以指示终端接入第n-2代移动通信网络,以实现终端接入第n-2代移动通信网络,提升终端业务性能。
作为一种可选的实施方式,上述第一消息为重定向消息。
这样通过上述重定向消息可以实现终端以重定向的方式接入或回退到第n-2代移动通信网络,以避免引入新流程,以降低终端的复杂度。
在一些实施方式中,上述第一消息还可以是配置消息或重配置消息等,具体对此不作限定。

步骤301、第一网络侧设备向终端发送第一消息,所述第一网络侧设备为第n代移动通信网络的网络侧设备,所述第一消息用于如下至少一项:指示测量第n-2代移动通信网络的小区、指示接入第n-2代移动通信网络,其中,n为大于或等于6的整数。

下面以第n代移动通信网络为6G网络,第n-1代移动通信网络为5G网络,第n-2代移动通信网络为4G网络为例,通过多个实施例对本申请实施例提供的方法进行举例说明:
实施例一:
本实施例主要描述通过切换(handover)的方式从6G网络直接回退到4G。
对应的信令流程如图9所示,图9中6G SMF+5G SMF+PGW-C是6G、5G和4G合设的网元,在6G+5G的情况下,可以替换为6G SMF+5G SMF;在6G+4G的情况下,可以替换为6G SMF+PGW-C;6G UPF+5G UPF+PGW-U是6G、5G和4G合设的网元,在6G+5G的情况下,可以替换为6G UPF+5G UPF;在6G+4G的情况下,可以替换为6G UPF+PGW-U。为了简化描述,后续将6G SMF+5G SMF+PGW-C简称为合设SMF。
如图9所示,包括如下步骤:
步骤0.UE在6G建立IMS PDU会话;
步骤1.合设SMF(6G SMF+5G SMF+PGW-C)发起建立语音承载请求。
步骤2.6G基站根据运营商策略配置UE测量4G小区。
运营商策略包括:不支持Vo6G,不支持VoNR。
步骤3.UE向6G基站发送测量报告,包含小区信息,如target eNB ID,target TAI;
步骤4.6G基站向6G AMF发送切换请求,包含第二指示信息,target eNB ID,target TAI,其中,第二指示信息用于指示切换到4G。
步骤5.6G AMF向合设SMF发送第一上下文请求(如PDU Session_Context Request),携带第三指示信息,第三指示信息用于指示获得PDN连接上下文的信息
合设SMF根据第三指示信息,向6G AMF发送PDN connection context。
步骤6.6G AMF向5G AMF发送上下文创建请求(CreateUEContext Request),包含第四指示信息,target eNB ID,target TAI,PDN connection context,其中,第四指示信息用于指示切换到4G。
步骤6的第四指示信息可以和步骤4的第二指示信息相同或不同,因为是通过不同消息发送的,因此在具体实现时,会通过不同的参数来表达该含义。
其中,这里的5G AMF是一个专用网元,专门用于6G向4G交互(interworking)时使用的网元。
步骤7.5G AMF根据第四指示信息进行MME的选择,具体是根据target eNB ID,target TAI选择MME。
步骤8.5G AMF向选定的MME发送迁移请求(Relocation request)(target eNB ID,target TAI,PDN connection context))
需要说明的是,步骤6-8是以6G AMF与MME无法直接通信,需要5G AMF中转为例进行介绍的。
若6G AMF与MME间有接口,则6-8可合并为1步,即6G AMF向MME发送Relocation request(target eNB ID,target TAI,PDN connection context))。
步骤9-10.MME根据PDN connection context向SGW发送会话创建请求(Create session request)。
步骤11-12.MME向4G基站发送切换请求(handover Request),4G基站为UE配置的无线资源信息
步骤13.MME向5G AMF发送迁移响应(relocation response),包含4G基站为UE配置的无线资源信息。
步骤14.5G AMF向6G AMF发送4G基站为UE配置的无线资源信息,如通过创建终端上下文响应(Communication_CreateUEContext response)发送无线资源信息。
需要说明的是,步骤13和14是以6G AMF与MME无法直接通信,需要5G AMF中转为例进行介绍的。
若6G AMF与MME间有接口,则6-8可合并为1步,即MME向6G AMF发送relocation response,包含4G基站发送为UE配置的无线资源信息。
步骤15-16.6G AMF向UE发送4G基站为UE配置的无线资源信息。
步骤17.UE根据4G基站为UE配置的无线资源信息接入4G基站,并发送切换完成(handover complete)消息。
步骤18.完成后续流程。
步骤19.合设SMF再次发起建立语音承载的请求,完成语音承载的建立。
通过本实施例的方案,可以让UE通过一次回退(fallback)过程,直接从6G fallback到4G,减少了语音呼叫的建立时延,提升了用户体验。
实施例二:
本实施例主要描述通过重定向的方式进行fallback的方案。
对应的信令流程图如图10所示,包括如下步骤:
步骤0-1.同于图9步骤0-1。
步骤2.6G基站根据运营商策略确定将UE重定向到4G。
运营商策略包括:不支持Vo6G,不支持VoNR。
步骤3(可选地).6G基站配置UE进行4G的策略,UE向6G基站发送4G小区的测量结果,包含target eNB ID,target TAI;
步骤4.6G基站向UE发送重定向消息,在重定向消息中包含用于指示UE接入4G网络的指示信息。
步骤5.UE通过4G基站向4G核心网MME发送TAU请求。
步骤6-7.MME向5G AMF请求UE的上下文。
5G AMF向6G AMF请求UE的上下文,携带第五指示信息,第五指示信息用于指示获得4G UE上下文或4G PDN连接上下文。
MME通过以下3种方法确定向5G AMF请求UE的上下文:
方法1:
UE在步骤5的TAU消息携带第一指示信息和GUTI-1,GUTI-1是UE根据6G GUTI映射(map)得到的4G GUTI;
MME根据第一指示信息确定向5G AMF发送请求,第一指示信息用于指示UE是从6G重选到4G的;或者,第一指示信息用于指示选择5G AMF;
MME在步骤6中包含GUTI-1,5G AMF根据GUTI-1确定6G AMF的地址,并向6G AMF发送上下文请求。
方法2:
UE在步骤5的TAU消息中包含GUTI-2,MME根据该GUTI-2确定5G AMF,GUTI-2是5G AMF为UE分配的5G GUTI;
GUTI-2的获得方法为:
UE在6G进行注册或移动性更新过程中,6G AMF向5G AMF发送请求消息,该请求消息用于请求为UE分配5G GUTI,在该请求消息中包含6G GUTI;
5G AMF向6G AMF发送5G GUTI,并保存6G GUTI和5G GUTI的对应关系;
6G AMF在注册或移动性更新响应消息中向UE提供该5G GUTI;
MME向5G AMF请求UE的上下文时,携带GUTI-2,5G AMF根据保存的对应关系和GUTI-2,获得6G GUTI,并根据6G GUTI确定6G AMF。
方法3:
UE在步骤5的TAU消息中包含2个GUTI,GUTI-1和GUTI-2;
GUTI-2的获得方法为:
UE在6G进行注册或移动性更新过程中,6G AMF向5G AMF发送请求消息,该请求消息用于请求为UE分配5G GUTI;
5G AMF向6G AMF发送5G GUTI;
6G AMF在注册或移动性更新响应消息中向UE提供该5G GUTI;
与方法2的区别:5G AMF不需要保存5G GUTI和6G GUTI的对应关系;
MME根据GUTI-2确定5G AMF,在步骤6中包含GUTI-1,5G AMF根据GUTI-1确定6G AMF
需要说明的是,这里的5G AMF是一个专用网元,专门用于6G向4G interworking是使用的网元。
需要说明的是,步骤6-7是以6G AMF与MME无法直接通信,需要5G AMF中转为例进行介绍的。
若6G AMF与MME间有接口,则6-7可合并为1步,即6G AMF向MME发送context request,该种情况下,仅能使用方法1。
步骤8.6G AMF向合设SMF发送第一上下文请求(如PDUSession_Context Request),携带第三指示信息,第三指示信息用于指示获得PDN连接上下文的信息;
合设SMF根据第二指示信息,向6G AMF发送PDN connection context。
步骤9.6G AMF向5G AMF发送UE的PDN connection context。
步骤10.5G AMF向MME发送UE的PDN connection context。
步骤11-12.MME根据PDN connection context向SGW发送Create session request。
步骤13.MME向UE发送TAU接受消息。
步骤14.合设SMF再次发起建立语音承载的请求,完成语音承载的建立。
通过本实施例的方案,可以让UE通过一次fallback过程,直接从6G fallback到4G,减少了语音呼叫的建立时延,提升了用户体验。
