Abstract
本申请提供了一种通信方法、装置、设备及系统,包括:数据分析网元确定目标终端设备的业务质量分析结果,并将该业务质量分析结果发送给接入网网元;接入网网元在接收到该业务质量分析结果后,可以根据该业务质量分析结果对目标终端设备进行切换判决。可以理解,由于业务质量分析结果可以反映出目标终端设备的业务质量高低,因此,接入网网元依据该业务质量分析结果对目标终端设备进行小区切换判决,也就提高了切换判决依据的可靠性。
Description
本申请涉及无线通信技术领域,特别是涉及一种通信方法、装置、设备及系统。
在无线通信网络中,诸如基站等接入网网元可能需要对接入的用户设备(User Equipment,UE)进行小区切换。比如,当UE当前所处小区的信号质量较差而其相邻小区的信号质量较好时,基站可以将UE由当前所处小区切换到信号质量更好的相邻小区,以使得UE在信号质量相对较优的小区中享受相应的业务服务。
目前,接入网网元通常是根据UE报告的测量报告对UE进行小区的切换判决,即,当测量报告表征UE当前所处小区的信号质量低于预设门限值,而相邻小区的信号质量又高于该预设门限值时,接入网网元可以确定将UE切换至该相邻小区。但是,基于测量报告对UE进行小区切换,可能并不能保证UE的业务质量,甚至还可能会降低UE的业务质量。
发明内容
为了解决上述问题,本申请实施例提供了一种通信方法、装置、设备及系统,以使得接入网网元能够依据更加可靠的切换判决依据对UE等终端设备进行小区切换判决。
第一方面,本申请实施例提供了一种通信方法,所述方法包括:接入网网元获取来自数据分析网元的目标终端设备的业务质量分析结果;所述接入网网元根据所述业务质量分析结果,对所述目标终端设备进行切换判决。在该实施方式中,由于业务质量分析结果可以反映出目标终端设备的业务质量高低,因此,当该业务质量分析结果表征终端设备的业务质量较低,不符合用目标终端设备的业务使用需求时,表明当前有必要通过切换目标终端设备所在小区的方式来提高目标终端设备的业务质量,此时,接入网网元可以依据该业务质量分析结果对目标终端设备进行小区切换判决,从而可以提高切换判决依据的可靠性。
在一种可能的实施方式中,所述接入网网元根据所述业务质量分析结果,对所述目标终端设备进行切换判决,包括:当所述业务质量分析结果满足第一预设条件时,所述接入网网元确定对所述目标终端设备进行小区切换;所述方法还包括:所述接入网网元对所述目标终端设备进行小区切换。在该实施方式中,接入网网元具体可以是在所接收到的业务质量分析结果满足一定预设条件时,如业务质量分析结果表征目标终端设备的业务质量较低时,确定对目标终端设备进行小区切换。相应的,在确定需要对目标终端设备进行小区切换后,接入网网元可以将目标终端设备由当前小区切换至另一个小区。
在一种可能的实施方式中,所述接入网网元根据所述业务质量分析结果,对所述目标终端设备进行切换判决,包括:当所述业务质量分析结果满足第一预设条件,且所述目标终端设备所处小区的信号质量满足第二预设条件时,所述接入网网元确定对所述目标终端设备进行小区切换。在该实施方式中,接入网网元在对目标终端设备进行小区切换判决时,不仅以目标终端设备的业务质量分析结果作为判决依据,还结合终端设备当前所处小区的信号质量进行综合考量,即当业务质量分析结果以及目标终端设备所处小区的信号质量均 满足相应的条件时,才确定对目标终端设备进行小区切换。
在一种可能的实施方式中,所述方法还包括:所述接入网网元确定所述第一业务质量分析结果对应的优先级信息以及所述第二业务质量分析结果对应的优先级信息;所述接入网网元根据所述业务质量分析结果,对所述目标终端设备进行切换判决,包括:所述接入网网元根据所述第一业务质量分析结果、所述第一业务质量分析结果对应的优先级信息、所述第二业务质量分析结果、所述第二业务质量分析结果对应的优先级信息,对所述目标终端设备进行切换判决。在该实施方式中,若接入网网元接收到至少两个业务质量分析结果,则可以根据各个业务质量分析结果对应的优先级信息,确定该业务质量分析结果的优先级,也即为确定接入网网元是根据哪个业务质量分析结果对终端设备进行小区切换判决。
在进一步可能的实施方式中,所述第一业务质量分析结果与所述第二业务质量分析结果对应于不同的业务类型或者不同的数据传输通道。在该实施方式中,数据分析网元可以为目标终端设备的不同类型的业务(如游戏业务、语音业务等)分别确定对应的业务质量分析结果,或者为目标终端设备不同的数据传输通道分别确定对应的业务质量分析结果等,以便于接入网网元根据目标终端设备的业务或者数据传输通道确定是否对目标终端设备进行小区切换。

在一些可能的实施方式中,所述业务质量分析请求中包含指示信息,所述指示信息用于指示请求所述目标终端设备在线业务对应的业务质量分析结果。在该实施方式中,接入 网网元在向数据分析网元请求目标终端设备的业务质量分析结果时,可以向数据分析网元只请求在线业务所对应的业务质量分析结果。其中,终端设备的在线业务,也即为终端设备当前正在进行的业务,如实时语音业务等。

从以上技术方案可以看出,接入网网元(如基站等)可以根据业务质量分析结果来对UE进行小区的切换判决,以提高切换判决依据的可靠性。具体实现时,数据分析网元可以确定针对于目标终端设备的业务质量分析结果,例如,数据分析网元可以是通过对与该目标终端设备相关的业务特征参数进行分析处理得到目标终端设备的业务质量分析结果等,相应的,该业务质量分析结果表征了目标终端设备的业务质量高低,则数据分析网元可以将该业务质量分析结果发送给接入网网元,如通过核心网网元将业务质量分析结果发送给接入网网元等;接入网网元在接收到该业务质量分析结果后,可以根据该业务质量分析结果确定是否对目标终端设备进行切换。可以理解,业务质量分析结果可以反映出目标终端设备的业务质量高低,而当该业务质量分析结果表征目标终端设备的业务质量较低,不符合目标终端设备的业务使用需求时,表明当前有必要通过切换目标终端设备所在小区的方式来提高目标终端设备的业务质量,此时,接入网网元依据该业务质量分析结果对目标终端设备进行小区切换判决,也就提高了切换判决依据的可靠性。
为了更清楚地说明本申请实施例中的技术方案,下面将对实施例描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请中记载的一些实施例,对于本领域普通技术人员来讲,还可以根据这些附图获得其他的附图。

在UE接入网络并与网络进行无线通信过程中,为尽可能使得UE能够处于信号质量较好的小区,当UE所处小区的信号质量较差时,诸如基站等接入网网元通常会将该UE切换至信号质量相对较好的小区中,以使得UE能够在信号质量相对较好的小区中享受业务服务。具体实现时,以基站为例,基站会要求UE报告测量报告,并且,当基站根据该测量报 告确定UE当前所处小区(也可以称之为本小区)的信号质量低于预设的切换门限同时其相邻小区的信号质量高于预设的切换门限时,基站决定将UE从当前小区切换至相邻小区。
但是,发明人经研究发现,接入网网元根据预先固定配置的切换门限对UE进行小区的切换判决,通常比较武断。在实际应用场景中,即使UE处于信号质量较高的小区,UE的业务质量也并不一定会高,相应的,UE在处于信号质量较低的小区时,UE的业务质量也并不一定会低。因此,接入网网元对UE进行小区切换判决时所依据的测量报告并不可靠,换句话说,接入网网元依据测量报告中所体现的小区信号质量对UE进行小区切换判决后,UE的业务质量可能并没有得到提高,甚至反而会出现业务质量降低的现象,比如数据下载速度变慢、浏览器页面长期未响应等。
基于此,本申请实施例提供了一种通信方法,接入网网元(如基站等)可以根据业务质量分析结果来对UE等终端设备进行小区的切换判决,以提高切换判决依据的可靠性。具体实现时,数据分析网元可以确定目标终端设备的业务质量分析结果,例如,数据分析网元可以是通过对与该目标终端设备相关的业务特征参数进行分析处理得到目标终端设备的业务质量分析结果等,相应的,该业务质量分析结果表征了目标终端设备的业务质量高低,则数据分析网元可以将该业务质量分析结果发送给接入网网元,如通过核心网网元将业务质量分析结果发送给接入网网元等;接入网网元在接收到该业务质量分析结果后,可以根据该业务质量分析结果对目标终端设备进行切换判决。可以理解,业务质量分析结果可以反映出目标终端设备的业务质量高低,而当该业务质量分析结果表征目标终端设备的业务质量较低,不符合用目标终端设备的业务使用需求时,表明当前有必要通过切换目标终端设备所在小区的方式来提高目标终端设备的业务质量,此时,接入网网元依据该业务质量分析结果对目标终端设备进行小区切换判决,也就提高了切换判决依据的可靠性。
实际应用中,本申请实施例可以应用于如图1a所示的示例性通信系统。该通信系统可以是支持第四代(fourth generation,4G)接入技术的通信系统,例如长期演进(long term evolution,LTE)接入技术;或者,该通信系统也可以是支持第五代(fifth generation,5G)接入技术通信系统,例如新无线(new radio,NR)接入技术;或者,该通信系统也可以是支持第三代(third generation,3G)接入技术的通信系统,例如(universal mobile telecommunications system,UMTS)接入技术;或者,该通信系统还可以是支持多种无线技术的通信系统,例如支持LTE技术和NR技术的通信系统。另外,该通信系统也可以适用于面向未来的通信技术。
在该通信系统中,终端设备101通过接入网(access network,AN)网元102接入核心网。
其中,该终端设备101包括但不限于:用户单元、用户站、移动站、移动台、远方站、远程终端设备、移动终端设备、用户终端设备、终端设备、无线通信设备、用户代理、用户装置、蜂窝电话、无绳电话、会话启动协议(session initiation protocol,SIP)电话、无线本地环路(wireless local loop,WLL)站、个人数字处理(personal digital assistant,PDA)、具有无线通信功能的手持设备、计算设备、连接到无线调制解调器的处理设备、车载设备、可穿戴设备、物联网中的终端设备设备、家用电器、虚拟现实设备、 未来5G网络中的终端设备设备或者未来演进的公共陆地移动网络(public land mobile network,PLMN)中的终端设备等。
接入网网元102可以是与终端设备101进行通信的网元。接入网网元可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域(小区)内的用户设备进行通信。接入网网元102可以与任意数目终端设备通信。接入网网元102与终端设备101之间可以有多个空口连接,例如,接入网网元102与终端设备101之间存在两个空口连接,分别用于传输数据流A和数据流B。接入网网元可以支持不同制式的通信协议,或者可以支持不同的通信模式。例如,该接入网网元102以是演进型基站(evolved node B,eNodeB),或者是无线保真接入点(wireless fidelity access point,WiFi AP)、或者是全球微波接入互操作性基站(worldwide interoperability for microwave access base station,WiMAX BS),或者是云无线接入网络(cloud radio access network,CRAN)中的无线控制器,或者该接入网网元可以为未来5G网络中的接入网网元或者未来演进PLMN中的接入网网元等。
核心网可以包括:控制面功能(control plane function,CPF)网元、用户面功能(user plane function,UPF)网元103、策略控制功能(policy control function,PCF)网元104以及NWDAF网元105。其中,控制面功能网元可以包括接入管理功能(access management function,AMF)网元106和会话管理功能(session management function,SMF)网元107。通过接入网网元102和用户面功能网元103,可以实现终端设备101和数据网络(data network,DN)108之间用户面数据的传输。
PCF网元104具有策略控制决策的功能,为网络提供策略。NWDAF网元105用于数据学习和分析。AMF网元106用于移动性管理、合法监听、接入授权以及鉴权等。SMF网元107用于实现会话和承载管理、地址分配等。DN108为用于传输数据的网络,具体的,DN108可以为互联网协议(internet protocol,IP)多媒体子系统(IP multimedia subsystem,IMS)服务器或者分组数据网络(packet data network,PDN)或者应用服务器(application server,App server)。
可以理解的是,在图1a所示的通信系统中,各组成网元的功能仅为示例性的,各个组成网元在应用于本申请的实施例中时,并非全部功能都是必需的。
在该通信系统中,NWDAF网元105可以确定终端设备101对应的业务质量分析结果,并将该业务质量分析结果通过PCF网元104、SMF网元107、AMF网元106以及UPF网元103中的一种或者多种网元传输至AN网元102;AN网元102可以根据接收到的业务质量分析结果对终端设备101进行小区的切换判决。比如,当业务质量分析结果表征终端设备101的业务质量较低时,可以将终端设备101由当前所处小区切换至相邻小区,以期望提高终端设备101的业务质量。
可以理解的是,上述场景仅是本申请实施例提供的一个场景示例,本申请实施例可以应用于任何可适用的场景中,而不局限于上述场景。比如,在其它可能的应用场景中,NWDAF105与AN102之间可以具有直接连接的数据传输通道,如超文本传输协议(HyperText Transfer Protocol,HTTP)通道等。这样,NWDAF网元105所确定的业务质量分析结果可以基于该数据传输通道直接传输至AN102中,从而AN102可以根据接收到的业务质量分析结果对终端设备101进行小区的切换判决。
或者,本申请实施例也可以是应用于如图1b所示的示例性通信系统。在通信系统中,UE与网元以及不同网元之间可以通过相应的业务接口或者点到点的接口进行通信,如UE可以通过N1接口与AMF网元进行通信,AN可以通过N3接口与UPF网元进行通信等(诸如N2、N4、N6以及N9等点到点的接口类似);又如,AMF网元可以通过业务接口Namf接口与网络中的其他网元进行通信,AF网元可以通过业务接口Naf接口与其它网元进行通信等。
下面结合附图,通过实施例来详细说明本申请实施例中一种通信方法的各种非限定性具体实现方式。
参阅图2,图2示出了本申请实施例中一种通信方法的流程示意图。本实施例所描述的通信方法可以应用于如图1a(或图1b)所示的通信系统中,本实施例中的数据分析网元可以是图1a所示的通信系统中的NWDAF网元105;核心网网元可以包括图1a中所示的PCF网元104、SMF网元107、AMF网元106以及UPF网元103中的一种或者多种网元;接入网网元可以是图1a所示的AN102;目标终端设备可以是图1a所示的终端设备101。该方法具体可以包括:
S201:数据分析网元确定目标终端设备的业务质量分析结果。
本实施例中,可以是对某个特定的终端设备(以下称之为目标终端设备,如可以是UE等)进行小区或者网络切换判决,其中,对该目标终端设备进行小区或者网元进行切换判决的判决依据可以是该目标终端设备的业务质量分析结果,而该业务质量分析结果可以由具有数据分析功能的网元进行确定,如NWDAF网元等。作为一种示例,所确定出的业务质量分析结果可以是数值的方式表征目标终端设备的业务质量高低,如可以利用1至5以内的数值对目标终端设备的业务质量进行表示,其中,数值1可以表示业务质量最差,数值5可以表示业务质量最高,数值越大,表征目标终端设备的业务质量越高;也可以是利用等级的方式表征目标终端设备的业务质量高低,比如,可以是利用“高”、“较高”、“中等”、“较低”、“低”等这样表示业务质量由高到低的等级值来表示业务质量的高低。
实际应用的一些实施方式中,数据分析网元可以是响应其它网元发送的业务质量分析请求而执行业务质量分析结果的确定过程。作为一种示例,可以是由接入网网元生成业务质量分析请求,并将其发送给数据分析网元,以向数据分析网元请求业务质量分析结果。这样,数据分析网元可以响应所接收到的业务质量分析请求,通过对业务特征参数进行相应的分析处理得到该业务质量分析结果。本实施例中,接入网网元可以是将业务质量分析请求发送给核心网网元,再由核心网网元该将业务质量分析请求转发给数据分析网元。当然,在本实施例以外的其它实施方式中,接入网网元也可以通过HTTP通道等预先建立的特定数据传输通道,将业务质量分析请求直接发送给数据分析网元,可以不用核心网网元进行转发。
在一些非限定性示例中,接入网网元可以是在接收到目标终端设备报告的测量报告时,向数据分析网元发送针对于该目标终端设备的业务质量分析请求。其中,目标终端设备可以是响应接入网网元下发的无线资源控制(radio resource control,RRC)连接重配置消息而报告该测量报告,该RRC连接重配置消息中可以携带测量配置信息,并且该测量配置信息中可以用于告知目标终端设备需要测量的对象(如同系统邻区列表中的频点)、测量触 发条件(如本小区信号质量低于某门限值)以及测量报告报告条件(如相邻小区的信号质量高于某门限值)等。或者,接入网网元可以是根据接收到的测量报告中所表征的信号质量来确定是否发送业务质量分析请求。具体的,接入网网元在接收到目标终端设备报告的测量报告后,可以先确定该测量报告中所表征的目标终端设备所处小区的信号质量是否满足相应的预设条件(为便于与后文预设条件区分,以下将其称之为第三预设条件),若确定本小区的信号质量满足第三预设条件,如本小区的参考信号接收功率(reference signal receiving power,RSRP)为-115db,小于预设门限值-110db等,则可以向数据分析网元发送针对于该目标终端设备的业务质量分析请求。其中,小区的信号质量可以利用该目标终端设备所测得的RSRP和/或参考信号接收质量(reference signal receiving quality,RSRQ)等进行表示。
而在其它可能的实施方式中,也可以是由核心网网元(如图1a中的PCF网元104)生成业务质量分析请求,并由核心网网元直接将该业务质量分析请求发送给数据分析网元。例如,在目标终端设备当前进行语音业务等在线业务时,核心网网元可以在业务建立时生成业务质量分析请求,或者也可以周期性的生成业务质量分析请求,并利用该业务质量分析请求向数据分析网元请求该目标终端设备对应的业务质量分析结果。
进一步的,数据分析网元在接收到业务质量分析请求后,可以响应该业务质量分析请求,并获取网络中用于生成该业务质量分析结果所对应的业务特征参数,例如数据分析网元可以向接入网网元和/或核心网网元发起数据订阅请求,以请求接入网网元和/或核心网网元报告相应的业务特征参数。该业务特征参数可以是与该目标终端设备的业务相关的数据,可以影响或者体现目标终端设备的业务质量的数据,如可以是为该目标终端设备分配的网络带宽、该终端设备的业务数据在传输过程中的丢包率等数据。然后,数据分析网元可以对获取的业务特征参数进行分析处理,从而得到能够反映该目标终端设备的业务质量高低的业务质量分析结果。
在一种示例性的具体实施方式中,业务特征参数可以被携带于业务质量分析请求中。具体的,数据分析网元所获取的业务特征参数可以包括接入网网元所能满足的接入网参数值,比如,可以包括接入网网元针对于目标终端设备的参数测量值(如下行数据的传输速度等)或者所能满足的参数值(如能保证的下行数据的传输速度),当业务质量分析请求由接入网网元生成时,接入网网元可以生成包括接入网参数值的业务质量分析请求,并将该接入网参数值随业务质量分析请求发送至数据分析网元。
此外,数据分析网元所获取的业务特征参数也可以包括核心网网元所能满足的核心网参数值,比如,可以是AMF网元、SMF网元、PCF网元以及AF网元等网元针对于目标终端设备的参数测量值或所能满足的参数值等。当业务质量分析请求由核心网网元生成时,核心网网元可以生成包含核心网参数值的业务质量分析请求,并将核心网参数值随业务质量分析请求发送至数据分析网元。而当业务质量分析请求由接入网网元生成时,核心网网元在接收到接入网网元发送的业务质量分析请求后,可以将核心网参数值添加至该业务质量分析请求中,并将包含核心网参数值的业务质量分析请求发送至数据分析网元。
上述实施方式中,业务特征参数可以随业务质量分析请求发送至数据分析网元,而在其它可能的实施方式中,也可以是数据分析网元要求接入网网元和/或核心网网元报告业务 特征参数。具体实现时,数据分析请求可以在接收到业务质量分析请求后,主动向接入网网元发送第一数据报告请求以请求接入网网元将接入网参数值报告给数据分析网元,和/或主动向核心网网元发送第二数据报告请求以请求核心网网元将核心网参数值报告给数据分析网元,从而使得数据分析网元能够获得生成业务质量分析结果所需的业务特征参数。
进一步的,数据分析网元在获取到业务特征参数后,可以是通过预先训练的业务质量分析模型来得到相应的业务质量分析结果。具体的,可以预先利用大数据分析或者机器学习等方法构建业务质量分析模型,并通过至少一组样本数据对业务质量分析模型进行训练,该样本数据包括作为模型输入的样本业务特征参数以及作为模型输出的样本业务质量分析结果,得到样本业务特征参数与样本业务质量分析结果之间的函数关系,其中,该样本业务特征参数具体可以是业务所在的时间、地点、天气、网络负载等参数,并可以由接入网网元或者核心网网元所测量得到。完成业务质量分析模型的训练后,数据分析网元可以将获取的业务特征参数输入至业务质量分析模型中,并利用该业务质量分析模型分析得到相应的业务质量分析结果。
值得注意的是,本实施例中,可以针对于每个终端设备确定出适用于该终端设备所对应的业务质量分析结果。其中,不同终端设备所对应的业务质量分析结果可能不同,比如,对于与同一基站无线连接的第一终端设备以及第二终端设备,可能第一终端设备所对应的业务质量分析结果表征第一终端设备的当前业务质量较差,而对于第二终端设备所对应的业务质量分析结果保证该第二终端设备的当前业务质量相对较好。
实际应用中,数据分析网元为目标终端设备所确定的业务质量分析结果具体可以是在线业务的业务质量分析结果。可以理解,对于目标终端设备的在线业务,也即目标终端设备当前正在执行的业务,为了尽可能的将终端设备的业务体验维持在较高的水平,可以在目标终端设备的业务质量较低时通过切换目标终端设备所在小区的方式来提高该目标终端设备的业务质量。为此,数据分析网元可以为目标终端设备确定出在线业务的业务质量分析结果,以便于基站根据该目标终端设备的在线业务的业务质量来确定是否对用户所处小区进行切换。
相应的,本实施例中可以通过指示信息来指示数据分析网元确定出目标终端设备的在线业务对应的业务质量分析结果。在一种示例性的具体实施方式中,数据分析网元所接收到的业务质量分析请求中可以包含第二指示信息,该第二指示信息可以用于指示请求目标终端设备在线业务对应的业务质量分析结果。其中,该第二指示信息可以是由接入网网元或者核心网网元将其添加至业务质量分析请求中。例如,当接入网网元在向数据分析网元请求该目标终端设备的业务质量分析结果时,可以先确定出该目标终端设备当前所执行的在线业务具体有哪些,并基于所确定的在线业务生成相应的第二指示信息,然后可以将该第二指示信息添加至业务质量分析请求中,使得第二指示信息随业务质量分析请求发送至数据分析网元。当然,该第二指示信息也可以是独立于业务质量分析请求而被单独发送给数据分析网元,本实施例中,对于数据分析网元从其它网元中获取该第二指示信息的具体实施方式并不限定。
值得注意的是,数据分析网元在没有获得特殊指示的情况下,也可以是默认生成目标终端设备的在线业务的业务质量分析结果,则,数据分析网元在生成业务质量分析结果后, 还可以进一步生成第一指示信息,该第一指示信息用于指示该业务质量分析结果为目标终端设备的在线业务所对应的业务质量分析结果。这样,当接入网网元接收到该第一指示信息时,可以明确所接收到的业务质量分析结果对应于目标终端设备的在线业务,而不是离线业务或者其它类型的业务等。
此外,实际应用的一些场景中,接入网网元以及核心网网元为目标终端设备提供的业务可能同时包括多个业务,比如,目标终端设备当前可以进行语音业务、图片下载业务等,相应的,对于数据分析网元所确定的业务质量分析结果,可以是针对于该目标终端设备所有业务的整体业务质量的分析结果,也可以是针对于该目标终端设备某特定业务的业务质量的分析结果,如针对于目标终端设备语音业务的业务质量的分析结果等。
当然,在数据分析网元为目标终端设备确定业务质量分析结果之前,可以预先为该目标终端设备建立相应的业务。比如,当目标终端设备启动游戏业务时,网络中的业务服务器可以向核心网网元发送业务建立请求,以请求核心网网元为该目标终端设备建立业务,并为目标终端设备的该业务建立相应的数据传输通道。
S202:数据分析网元将业务质量分析结果发送给核心网网元。
本实施例是以应用于图1a所示的通信系统为例对本申请实施例的技术方案进行示例性说明。基于此,数据分析网元在确定出业务质量分析结果后,可以将该业务质量分析结果发送给核心网网元,以便于由核心网网元将该业务质量分析结果转发给接入网网元。
当然,在其它实施例中,数据分析网元与接入网网元之间可以直接进行数据通信,如可以基于HTTP通道等数据传输通通道直接进行通信等,此时,数据分析网元可以基于预先建立的数据传输通道将该业务质量分析结果直接发送给接入网网元。
S203:核心网网元将接收到的业务质量分析结果转发给接入网网元。
S204:接入网网元根据接收到的业务质量分析结果,对目标终端设备进行切换判决。
具体实现时,当接入网网元确定所接收到业务质量分析结果满足第一预设条件时,接入网网元可以确定需要将目标终端设备由当前所处小区(即本小区)切换至其它小区中,以期望在将目标终端设备切换其它小区后,目标终端设备的业务质量能够得到提升。在一种示例中,第一预设条件可以是接入网网元所接收到的业务质量分析结果表征目标终端设备的业务质量较低,如业务质量分析结果为2分(满分为5分),或者业务质量分析结果所表征的业务质量等级为“低”等。当然,当接入网网元确定该业务质量分析结果不满足第一预设条件时,目标终端设备可以继续处于本小区,而可以不用对目标终端设备进行小区切换。
在另一种可能的具体实施方式中,接入网网元可以同时基于接收到的业务质量分析结果以及目标终端设备所报告的测量报告来确定是否对目标终端设备进行小区切换。具体的,当接入网网元确定接收到的业务质量分析结果满足第一预设条件的同时,接入网网元根据目标终端设备报告的测量报告还确定目标终端设备所处小区的信号质量满足第二预设条件,则接入网网元可以确定对目标终端设备进行小区切换。在一个示例中,第二预设条件具体可以是目标终端设备所处小区的信号质量低于预设门限值,如目标终端设备所测量的RSRP值小于-120db等。值得注意的是,在该实施方式中,当接入网网元确定对目标终端设备进行小区切换后,接入网网元可以根据测量报告中所表征的目标终端设备对于相邻小区 的信号质量测量结果,确定要将目标终端设备具体切换至哪个相邻小区,所要切换至的相邻小区的信号质量相对较高。相应的,当接入网网元确定该业务质量分析结果不满足第一预设条件,或者,测量报告中所表征的小区信号质量不满足第二预设条件时,接入网网元可以不对目标终端设备进行小区切换。
而在又一种可能的具体实施方式中,由于目标终端设备当前所执行的业务可能包含多个业务,比如实时语音业务以及游戏业务等,而目标终端设备处于本小区时,目标终端设备的不同业务的业务质量可能并不相同,比如,对于实时语音业务而言,其业务质量较高(如通话流畅不卡顿等),而对于游戏业务而言,其业务质量较低(如用户操作响应延时较大、画面卡顿等),因此,本实施例中,接入网网元可以针对目标终端设备所进行的业务的重要程度来对目标终端设备进行切换判决。具体的,数据分析网元所确定的业务质量分析结果可以包括多个业务对应的业务质量分析结果,以包括第一业务质量分析结果与第二业务质量分析结果为例,第一业务质量分析结果以及第二业务质量分析结果对应于不同的业务类型,则接入网网元可以确定出该第一业务质量分析结果所对应的优先级信息,以及第二业务质量分析结果所对应的优先级信息,然后根据该第一业务质量分析结果、第一业务质量分析结果所对应的优先级信息、第二业务质量分析结果以及第二业务质量分析结果所对应的优先级信息,对目标终端设备进行切换判决。作为一种示例,若第一业务质量分析结果对应的优先级信息所表征的优先级,高于第二业务质量分析结果对应的优先级信息所表征的优先级,则接入网网元可以根据第一业务质量分析结果所表征的业务质量高低来确定是否对目标终端设备进行小区切换,反之,若第二业务质量分析结果对应的优先级信息所表征的优先级更高,则接入网网元可以根据第二业务质量分析结果来对目标终端设备进行小区的切换判决。
其中,优先级信息可以配置于接入网网元中,也可以是核心网网元下发给接入网网元,比如可以是由核心网网元中的PCF网元或者SMF网元下发等。这样,接入网网元接收到业务质量分析结果后可以直接获取到相应的优先级信息。
值得注意的是,业务质量分析结果不仅可以包括多个业务类型对应的业务质量分析结果,还可以包括多个数据传输通道对应的业务质量分析结果,即,优先级信息不仅可以对应于不同的业务类型,比如,游戏业务的优先级高于实时语音业务的优先级等,还可以对应于不同的数据传输通道,比如,可以预先设定数据传输通道1的优先级高于数据传输通道2的优先级等。其中,在4G通信网络中,该一个数据传输通道可以为一个承载;在5G通信网络中,一个数据传输通道可以为一个服务质量流(quality of service flow,QoS flow)。
在一些可能的实施方式中,目标终端设备的业务质量可以通过网络参数的调整而可以得到提高。比如,当目标终端设备的业务质量较低时,核心网网元(如PCF)可以调整分配给该目标终端设备的带宽等资源参数等。因此,核心网网元在接收到数据分析网元发送的业务质量分析结果后,可以确定该业务质量分析结果是否满足第四预设条件,比如,该第四预设条件可以是该业务质量分析结果所表征的目标终端设备的业务质量较低等,若是,则核心网网元可以调整业务质量分析结果所对应的网络参数值,如核心网可以增加目标终端设备的带宽等QoS参数。
进一步的,数据分析网元生成业务质量分析结果所需的业务特征参数,可以包括网络中针对于该目标终端设备的网络参数值,则,在核心网网元实际指示接入网网元调整网络参数值之前,核心网网元可以将调整后的网络参数值(接入网网元实际未调整,以下称之为更新的网络参数值)发送给数据分析网元,由数据分析网元根据该更新的网络参数值进行分析,得到更新业务质量分析结果,并将该更新业务质量分析结果发送给核心网网元。
可以理解,若该更新业务质量分析结果表征目标终端设备的业务质量较高,这表明当核心网网元指示接入网网元对当前的网络参数值进行调整,并将其调整为前述更新的网络参数值后,目标终端设备的业务质量可以得到提高并达到符合目标终端设备的实际使用需求的水平。这样,当核心网网元实际在指示接入网网元按照该更新的网络参数值对当前网络参数值进行调整后,由于目标终端设备的业务质量可以得到提高,从而接入网网元可以无需对目标终端设备进行小区切换,进而可以尽可能的减少目标终端设备的小区切换次数。
而若更新业务质量分析结果表征目标终端设备的业务质量较低,这说明核心网网元若指示接入网网元调整网络参数值后,目标终端设备的业务质量仍然不会提高或者是不会提高至符合目标终端设备实际使用需求的水平,此时,核心网可以进一步提高网络参数值,以确定出合适的网络参数值,或者将原先的业务质量分析结果发送给接入网网元,以使得接入网网元对目标终端设备进行小区切换。
其中,对于核心网网元所接收到的业务质量分析结果或者更新业务质量分析结果,可以发送给接入网网元,以便于接入网网元确定是否对目标终端设备进行小区切换判决。
此外,本实施例中,数据分析网元可以是在该业务质量分析结果满足第二报告条件时才将业务质量分析结果报告给接入网网元,其中,该第二报告条件可以是基站或者核心网网元发送给数据分析网元。比如,数据分析网元可以是在业务质量分析结果的数值低于报告门限值时,才将业务质量分析结果报告给接入网网元等。可以理解,当业务质量分析结果表征目标终端设备的业务质量较低时,数据分析网元可以通过该业务质量分析结果通知接入网网元对目标终端设备进行小区切换,而当业务质量分析结果表征目标终端设备的业务质量较高时,数据分析网元可以不用发送给接入网网元,从而可以减少网络中设备之间的数据交互次数。尤其是当接入网网元或者核心网网元定期向数据分析网元订阅业务质量分析结果时,目标终端设备的业务质量在大多数时间段内均处于较高的状态,相应的,在该时间段内,接入网网元也可以不用对目标终端设备进行小区切换,此时,数据分析网元在用户业务质量较高时不反馈业务质量分析结果,可以有效减少网络中设备之间的数据交互次数,降低资源消耗。
在其它可能的实施方式中,还可以是通过减少各网元所报告的数据量来减少数据传输时的资源消耗。具体的,数据分析网元在获取业务特征参数时,可以从网络中的接入网网元、核心网网元、AF网元等网元中获取相应的业务特征参数,在此过程中,数据分析网元可以向各网元下发相应的第一报告条件,当各网元中所测量或者所满足的业务特征参数满足相应的第一报告条件,则可以将其报告给数据分析网元,以供数据分析网元生成业务质量分析结果,而当各网元中所测量或者所满足的业务特征参数不满足相应的第一报告条件时,则可以不进行报告。
可以理解,当目标终端设备的业务质量较低时,部分网元所测量的或者所能满足的该 目标终端设备的业务质量的业务特征参数(也可以称之为业务质量影响因素)可能降低了目标终端设备的业务质量,而其它网元上的业务特征参数并没有降低目标终端设备的业务质量,因此,数据分析网元可以仅接收部分网元上传的降低目标终端设备的业务质量的业务特征数据(也即为满足第一报告条件的数据),以便对这些数据进行分析处理得到目标终端设备的业务质量分析结果。比如,接入网网元在向数据分析网元报告目标终端设备的上行数据传输速率的测量值时,若确定该上行数据传输速率低于预设传输速率(满足第一报告条件),表明该上行数据传输速率降低了目标终端设备的业务质量,则可以将该上行数据传输速率报告给数据分析网元;反之,若确定该上行数据传输速率低于预设传输速率,表明该上行传输速率并没有降低目标终端设备的业务质量,则可以不报告该上行数据传输速率。这样,在实现对目标终端设备的业务质量进行有效分析的同时,还可以减少数据的传输量,从而可以尽可能的降低业务质量分析过程对网络的影响。
在进一步可能的实施方式中,各网元报告业务特征参数时所需满足的第一报告条件,可以是由数据分析网元预先配置的或根据接入网网元或者核心网网元发送的第二报告条件进行确定的。例如,假设核心网网元指示数据分析网元当业务质量分析结果的数值低于3时,将该业务质量分析结果发送给接入网网元,则数据分析网元可以根据该数值3计算出各网元报告业务特征参数时所需满足的报告条件,如数据分析网元可以根据该数值3确定接入网网元所报告的目标终端设备的上行数据传输速率不大于300Kbps(千比特每秒或千比特率)等。
本实施例中,数据分析网元可以确定针对于目标终端设备的业务质量分析结果,例如,数据分析网元可以是通过对与该目标终端设备相关的业务特征参数进行分析处理得到目标终端设备的业务质量分析结果等,相应的,该业务质量分析结果表征了目标终端设备的业务质量高低,则数据分析网元可以将该业务质量分析结果发送给接入网网元;接入网网元在接收到该业务质量分析结果后,可以根据该业务质量分析结果确定是否对目标终端设备进行切换判决。可以理解,业务质量分析结果可以反映出目标终端设备的业务质量高低,而当该业务质量分析结果表征目标终端设备的业务质量较低,不符合目标终端设备的业务使用需求时,表明当前有必要通过切换目标终端设备所在小区的方式来提高目标终端设备的业务质量,此时,接入网网元依据该业务质量分析结果对目标终端设备进行小区切换判决,也就提高了切换判决依据的可靠性。
为了便于理解,下面结合具体场景对本申请实施例的技术方案进行示例性说明。参阅图3,图3示出了本申请实施例中一种通信方法的信令交互示意图,在该实施例中,目标终端设备具体为UE,接入网网元具体可以是基站,核心网网元可以包括AMF、SMF、PCF以及AF,数据分析网元具体可以是NWDAF;并且,本实施例中的业务质量分析结果具体可以是平均意见分(mean opinion score,MOS)分数。该方法具体可以包括:
S301:NWDAF预先获取UE、基站以及各核心网网元上针对于UE的业务特征参数,并基于所获取的业务特征参数训练得到业务质量分析模型。
本实施例中,NWDAF可以预先收集用于模型训练的样本数据,并基于所获取的样本数据训练出业务质量分析模型,其中,该业务质量分析模型可以基于输入的业务特征参数输 出得到相应的业务质量分析结果。本实施例中,该业务质量分析结果具体可以利用MOS分数来表征。
具体实现时,该业务质量分析模型可以预先利用大数据分析或者机器学习等方法进行构建,并利用从UE、基站以及各核心网网元中获取的样本数据对业务质量分析模型进行训练,该样本数据包括作为模型输入的样本业务特征参数以及作为模型输出的样本MOS分数,得到样本业务特征参数与样本MOS分数之间的函数关系,其中,该样本业务特征参数具体可以是业务所在的时间、地点、天气、网络负载等参数。值得注意的是,在训练业务质量分析模型时,所使用的样本数据可以是一个或者多个UE的业务的业务特征数据以及相应的业务质量评分。而在利用完成训练的业务质量分析模型来确定出某特定UE的业务质量分析结果时,输入至该业务质量分析模型的业务特征数据可以是单个UE的业务特征数据。
S302:AF向PCF发送策略认证建立请求,以触发为UE的相应业务建立数据传输通道。
S303:PCF根据策略认证建立请求中的业务描述信息,触发网络侧为该UE的业务建立数据传输通道。
本实施例中,当UE请求某种业务(比如语音业务)时,可以为该UE建立相应的业务。具体实现时,AF可以向PCF下发针对于该UE的策略认证建立请求,该策略认证建立请求至少可以包括UE的标识以及UE所请求业务的业务描述信息。其中,该业务描述信息可以包括此次建立业务的要求信息,如该业务所需的带宽、时延以及MOS分数要求等信息。
这样,PCF可以根据接收到的业务描述信息,触发网络侧SMF为用户设备所请求的业务建立数据传输通道,以便于该用户设备的业务数据可以基于该数据传输通道在各网元中进行数据传输。
具体实现时,当本实施例应用于5G场景下,PCF可以触发PDU session修改流程,该流程中网络侧可以建立专有的服务质量流(QoS flow),该QoS flow即为前述数据传输通道,可以用于传输该业务相关的数据。而当本实施例应用于4G场景下时,PCF可以触发专有承载建立流程,所建立的承载即为前述数据传输通道,可以用于传输该业务相关的数据。
S304:基站向UE下发RRC连接重配置消息,该RRC连接重配置消息包括测量对象、测量触发条件以及测量报告的报告条件。
本实施例中,基站可以指示UE上传测量报告,具体可以是向UE下发RRC连接重配置消息,其中,该RRC连接重配置消息包括用于告知UE需要测量的对象、触发UE对相邻小区的信号质量进行测量的触发条件以及UE向基站报告测量报告时所需满足的报告条件。
S305:当UE基于RRC连接重配置消息确定当前满足测量报告的报告条件时,向基站报告测量报告。
具体的,UE在接收到该RRC连接重配置消息后,可以测量本小区的RSRP或者RSRQ(信号质量)是否满足触发条件,具体可以是RSRP或者RSRQ是否低于预设门限值,若满足,则UE可以根据RRC连接重配置消息中的测量对象,确定本小区的相邻小区,并对相邻小区的RSRP或者RSRQ进行测量,得到相邻小区的RSRP或者RSRQ值。进一步的,若基站确定相邻小区的RSRP或者RSRQ值大于预设门限值,则UE可以将用户设备对本小区以及相邻小区的测量报告报告给基站。
S306:基站根据接收到的测量报告,生成针对于该UE的业务质量分析请求,并将其发 送给NWDAF。
本实施例中,当基站接收到UE报告的测量报告时,可以触发基站生成业务质量分析请求,并将其发送给NWDAF。在其它实施方式中,基站也可以是在接收到的测量报告后,根据该测量报告确定本小区的RSRQ或者RSRQ是否满足预设条件,若是,则可以触发基站生成业务质量分析请求,并将其发送给NWDAF,而若不是,则可以不用对该用户设备进行小区切换。
进一步的,在基站生成业务质量分析请求的过程中,可以将NWDAF生成业务质量分析结果所需的业务特征参数添加至该业务质量分析请求中,并随业务质量分析请求发送给NWDAF。其中,基站所添加的业务特征参数可以是基站所测量或者所能满足的参数值,如基站对用户设备的上行信号的测量值等;当然,基站所添加的业务特征参数还可以是UE报告的测量报告中的测量数据(如RSRP、RSRQ的实际测量值等),或者可以是基站对于测量数据经过中间处理后的数值结果,用于表征基站当前能满足或能保证的参数值。
值得注意的是,由于NWDAF在实际应用中所提供的数据处理服务包括多种,比如,NWDAF可以对终端进行移动轨迹预测、分析UE的业务质量等,因此,基站在请求NWDAF提供数据处理服务时,还可以在该业务质量分析请求中添加分析类型标识(analytic ID),以便于NWDAF基于该分析类型标识确定对UE进行业务质量分析处理。
实际应用的一些场景中,若NWDAF部署于远端核心网,则基站可以是通过控制面网络功能(network function,NF)网元向NWDAF发送业务质量分析请求。其中,NF网元可以包括AMF、SMF以及PCF网元中的一种或多种等网元。
具体实现时,基站可以通过N2接口向AMF发送该业务质量分析请求,该N2接口具体为基站与AMF之间的通信接口。然后,AMF可以直接利用与NWDAF之间的服务化接口将该业务质量分析请求发送给NWDAF,也可以是先向SMF转发来自基站的该业务质量分析请求,再由SMF将该业务质量分析请求通过与NWDAF之间的服务化接口发送给NWDAF,或者SMF将该业务质量分析请求转发给PCF,再由PCF利用与NWDAF之间的接口将该业务质量分析请求发送给NWDAF。
值得注意的是,各网元在传输业务质量分析请求的过程中,可以将自身所获取的针对于该用户设备的业务相关数据添加至该业务质量分析请求中,该业务相关数据可以是各网元所测量的数据,也可以是各网元所能满足的数据,并随业务质量分析请求报告给NWDAF,以便NWDAF通过分析这些数据生成相应的业务质量分析结果。作为一种示例,AMF可以报告UE的位置(location)、移动模式(mobility pattern),SMF可以报告SMF的负载(load)、服务质量流的上行或下行流量以及持续时间(UL/DL volume and duration),PCF可以报告该用户设备业务的服务要求(service requirement)信息等。这样,NWDAF在接收到该业务质量分析请求后,可以不用再向这些网元请求其报告相应的业务特征参数,从而可以减少NWDAF与各网元之间数据交互次数,也可以缩短基站获取业务质量分析结果的时延。
当然,在其它实施方式中,NWDAF也可以是在接收到业务质量分析请求后,主动向各网元发送响应的数据报告请求,以请求各网元向NWDAF报告相应的业务特征参数。具体实现时,可以根据实际使用的需求自行设定,在此不做限定。
S307:NWDAF响应于接收到的业务质量分析请求,获取该UE对应的业务特征参数。
具体实现时,若NWDAF所接收到的业务质量分析请求中携带有业务特征参数,则NWDAF可以从该请求中解析出所需的业务特征参数;若该业务质量分析请求中未携带有业务特征参数,或者所携带的业务特征参数不全,则NWDAF可以请求网络中相应的网元报告业务特征参数。比如,NWDAF可以分别向AMF请求UE location、向UPF请求flow bitrate、向SMF请求SMF load、向AF请求media codec等。
其中,为了减少NWDAF所接收的业务特征参数的数据量,本实施例中,各个网元在报告相应的业务特征参数时,可以限定各个网元所报告的业务特征参数需要满足特定的报告条件,当业务特征参数不满足该报告条件时,相应网元可以不将其报告给NWDAF。其中,各个网元对应的报告条件可以是由NWDAF的MOS分数报告条件进行确定,而该MOS分数的报告条件是指当MOS分数满足该报告条件时,NWDAF向基站报告MOS分数,而当MOS分数满足该报告条件时,该MOS分数不报告给基站。
S308:NWDAF对所获取的业务特征参数进行分析处理,得到UE的业务相应的MOS分数。
本实施例中,NWDAF可以利用预先构建的业务质量分析模型来得到业务质量分析结果。具体的,NWDAF可以将所获取的业务特征参数输入至该业务质量分析模型中,由业务质量分析模型输出业务相应的MOS分数。
S309:NWDAF将该MOS分数发送给基站。
具体实现时,对应基站向NWDAF传输业务质量分析请求的发送方式,NWDAF在向基站发送MOS分数时,可以是通过控制面网络功能(network function,NF)网元向基站发送MOS分数,也可以是通过直接向基站发送MOS分数。其具体实现过程,可参阅前述业务质量分析请求的数据传输过程的相关之处描述,在此不做赘述。
进一步的,当MOS分数经过PCF传输至基站时,PCF可以根据所接收到的MOS分数调整UE的该业务对应的网络参数值,该网络参数值将影响UE的业务质量的高低。具体的,当MOS分数低于预设分数,如低于3分时,PCF可以适应性的提高UE对应的QoS参数和/或RSRP等网络参数值,以期望通过提高该网络参数值来提高UE的业务质量。在实际调整之前,PCF可以将调整后的网络参数值(网络中的网络参数值实际尚未调整)发送给NWDAF,并请求NWDAF基于该调整后的网络参数值重新生成MOS分数,并接收该NWDAF发送的更新的MOS分数。若更新的MOS分数不低于预设分数,则PCF可以指示基站按照调整后的网络参数值进行相应的参数调整,而若更新的MOS分数依然低于预设分数,则PCF可以将原先的MOS分数发送给基站,以便于基站根据该MOS分数进行小区切换判决。
S310:基站根据接收到的MOS分数,确定是否对UE进行小区切换。
具体实现时,基站在接收到MOS分数后,若确定该MOS分数小于预设分数,则基站可以确定UE的业务质量较差,从而可以执行对UE的小区切换流程;而若确定该MOS分数不小于预设分数,则基站可以确定当前无需对UE进行小区切换。
实际应用中,基站还可以结合MOS分数以及UE报告的测量报告进行综合判断,比如,当基站确定MOS分数低于预设分数,且,测量报告中所包含的UE的RSRP值低于-120db时,基站确定需要对UE进行小区切换,而当基站确定MOS分数高于预设分数,或者,测量报告中所包含的UE的RSRP值高于-120db时,则基站确定当前可以不用对UE进行小区切换。
进一步的,NWDAF可以为UE的不同业务确定出不同的MOS分数,或者是为UE对应的 不同数据传输通道确定不同的MOS分数,因此,基站可以接收到NWDAF发送的至少两个MOS分数,对应于不同的业务或者不同的数据传输通道。而在进行小区切换判决时,基站可以是根据业务之间的优先级或者数据传输通道之间的优先级,确定根据哪个MOS分数来决定是否对UE进行小区切换。比如,以业务优先级为例,若基站接收到语音业务对应的MOS分数以及游戏业务对应的MOS分数,则基站可以通过查表或者PCF下发的优先级信息,确定游戏的优先级高于语音业务的优先级,这样,当游戏业务的MOS分数较低时,即使语音业务的MOS分数较高,基站也会因为优先级更高的游戏业务的业务质量较低而最终确定对UE进行小区切换;而当游戏业务的MOS分数较高时,即使语音业务的MOS分数较低,基站也不会切换UE所在的小区。
值得注意的是,上述实施例中是以基站发起业务质量分析请求进行示例性说明,在其它可实现的实施例中,也可以是PCF等网元生成业务质量分析请求,并将其发送给NWDAF。如图4所示,在步骤S306中,可以由PCF生成业务质量分析请求,并将其发送给NWDAF,这样,NWDAF在生成MOS分数后,可以将该MOS分数通知给基站,以便于基站根据该MOS分数确定是否为相应的UE切换其所处小区。
