请参考图1,其示出了本公开实施例提供的一种无线通信***的结构示意图。如图1所示,无线通信***是基于蜂窝移动通信技术的通信***,该无线通信***可以包括:若干个用户设备110以及若干个基站120。
其中,用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备110可以是物联网用户设备,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者,用户设备110也可以是无人飞行器的设备。或者,用户设备110也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线用户设备。或者,用户设备110也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。

其中,基站120可以是4G***中采用的演进型基站(eNB)。或者,基站120也可以是5G***中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体接入控制(Medium Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站120的具体实现方式不加以限定。

XR业务和/或媒体业务要求更高的吞吐量和更低的延迟、具有更高功耗和消耗更多的网络资源。因此,需要考虑QoS和设备功耗的权衡。目前尚没有相应QoS和策略机制,来满足以上一系列相应需求。
因此,如何平衡UE能耗和XR业务/媒体业务的传输性能,如,平衡UE电池时长和数据业务的吞吐量、时延、可靠性等,是亟待解决的问。
如图2所示,本公开实施例提供一种信息传输方法,由SMF执行,包括:
步骤201:向接入网功能发送UE的UE状态信息,其中,所述UE状态信息用于供所述接入网功能确定所述UE的业务数据流传送和/或所述业务数据流传送的QoS参数。
UE状态信息可以用于指示UE的状态。UE状态可以包括但不限于以下至少之一项:UE的负载状况、UE电池状况、UE的温度状况、UE的功耗状况等。
UE状态信息可以用于由接入网功能确定业务数据流传送和/或所述业务数据流传送的服务质量QoS参数。这里,接入网功能可以由基站等接入网设备实现。
在一个可能的实施方式中,由接入网功能确定业务数据流传送,包括:由接入网功能确定是否进行业务数据流传送。
业务数据流可以具有一个或多个。接入网功能可以确定进行传送的一个或多个业务数据流。
这里,QoS参数包括但不限于以下至少之一项:(1)QoS等级指示(QoS Class Identifier,QCI);分配保留优先级(Allocation and Retention Priority,ARP);保证比特速率(Guaranteed Bit Rate,GBR);最大比特速率(Maximum Bit Rate,MBR);组合最大比特速率(Aggregated Maximum Bit Rate,AMBR)。这里,QoS可以是针对业务数据流的。
这里,可以针对不同的UE状态,设置不同的QoS参数。例如,可以针对不同的UE电池电量等级,设置不同的QoS参数。如,针对UE电池电量较低的电量等级,可以配置能耗较低的QoS参数。
在一个可能的实现方式中,业务数据流传送和/或所述业务数据流传送的服务质量QoS参数可以对UE状态产生影响。
在一个实施例中,所述UE状态信息,至少用于指示以下至少之一项:
所述UE的电池电量;
所述UE的电池使用时长;
所述UE的供电模式;
所述UE的温度状态。
UE的电池电量可以采用电池电量等级表示。例如,可以将电池电量从0%至100%划分为多个电池电量等级,不同电池电量等级指示不同电池电量范围。
UE的电池使用时长可以包括以下至少之一项:电池剩余电量的使用时长、电池已使用时长等。
UE的供电模式可以包括以下至少之一项:电池供电、外部电源(如市电供电)、混合供电(电池结合市电供电等)。
UE的温度状态可以包括UE不同测温点中一个或多个测温点的温度。例如UE的温度状态可以包括以下至少之一项:UE处理器的温度状态、UE电池的温度状态。
在一个可能的实现方式中,UE的温度状态采用电池温度等级表示。例如,UE的温度状态可以采用高、中、低三个温度等级表示。
在一个实施例中,所述UE的业务数据流,包括以下至少之一项:
所述UE的扩展现实XR类业务数据流;
所述UE的多模态数据业务数据流。
XR类业务数据流通常具有高带宽、低时延和高可靠性需求的特点,因此导致UE耗能突出。这里业务与UE状态信息指示的UE状态具有强相关性。
多模态数据业务数据流用于传输不同模态的数据,因此,同样具有高带宽、低时延和高可靠性需求的特点,因此导致UE耗能突出。这里业务与UE状态信息指示的UE状态具有强相关性
例如,XR类业务数据流会较大消耗电池电量,提升UE的温度等。
这里,可以由接入网功能等根据UE状态信息确定允许传输和/或不允许传输的业务数据流,传输的业务数据流的QoS参数。
在一个可能的实现方式中,接入网功能可以确定满足于UE状态信息指示的UE状态的业务数据流传送和/或所述业务数据流传送的服务质量QoS参数。
例如,当UE电池电量较低,或UE温度较高时,可以减少业务数据流传送,使业务数据流传送的能耗降低,从而提高电池供电时长、降低UE温度。
当UE电池电量较低,或UE温度较高时,可以调节QoS参数,降低传输带宽等,使业务数据流传送的能耗降低,从而提高电池供电时长、降低UE温度。
再例如,当UE由市电供电并且UE温度较低时,可以调节QoS参数,提高传输带宽、降低传输时延等;从而提高用户体验。
这里,可以由核心网网元SMF向接入网功能发送UE状态信息。不由UE直接向接入网功能发送UE状态信息。可以减少由于UE直接向接入网功能发送UE状态信息对空口数据传输的影响,提高兼容性。
在一个可能的实现方式中,UE状态信息是由UE通过NAS消息发送给核心网的。
UE可以确定自身的UE状态,并通过UE状态信息发送给核心网。UE状态信息可以携带在NAS消息中发送给核心网,如发送给AMF、SMF、PCF和/或UMD等。再由核心网网元如SMF等发送给接入网功能。
如此,通过SMF向接入网功能发送UE的UE状态信息,接入网功能根据UE状态信息确定UE的业务数据流传送和/或业务数据流传送的QoS参数,一方面,平衡UE能耗等UE状态和XR媒体业务等业务数据流的传输性能。另一方面,通过SMF向接入网功能发送UE状态信息,可以减少由于UE直接向接入网功能发送UE状态信息对空口数据传输的影响,提高兼容性。
如图3所示,本公开实施例提供一种信息传输方法,由SMF执行,包括以下至少之一项:
步骤301a:接收所述UE发送的所述UE状态信息;
步骤301b:接收来自UDM的所述UE状态信息;
步骤301c:接收来自PCF的所述UE状态信息。
步骤301a和/或步骤301b和/或步骤301c可以单独实施,也可以结合步骤201一起实施。
在一个可能的实现方式中,UE状态信息可以是UE发送给SMF的。例如,UE状态信息可以携带在NAS中发送给SMF。
在一个可能的实现方式中,UE状态信息可以是UE预先发送给核心网网元,并存储在UDM中的。
在一个可能的实现方式中,UE状态信息可以是UE预先发送给核心网网元,并存储在PCF中的。
在一个可能的实现方式中,UE状态信息可以是UE的应用发送给核心网的AF,并由AF发送给NEF,再由NEF存储在UDM中的。
在一个可能的实现方式中,UE状态信息可以与有效时长相关联。有效时间可以存储在UDM/UDR和NF中。UDM可以在有效时长内,向核心网网元(例如,AMF和/或SMF)提供UE状态信息。在有效期届满时,每个节点都会自动删除UE状态信息。UDM可以无需显式信令删除UE状态信息。
在一个可能的实现方式中,UDM可以预先授权AF和/或NEF传输UE状态信息。例如:UDM可以预先授权AF和/或NEF传输携带UE状态信息的通信信令。
SMF可以通过订阅等方式从UDM获取UE状态信息。SMF也可以通过到UDM检索等方式从UDM获取UE状态信息。
在一个可能的实现方式中,UE状态信息可以是UE的应用发送给核心网的AF,并由AF发送给NEF,再由NEF存储在UDM中的。
在一个可能的实现方式中,UE状态信息可以是UE发送给PCF的。
在一个可能的实现方式中,UE状态信息可以是UE的应用发送给核心网的AF,并由AF发送给PCF中的。这里,AF可以是可信的AF。
在一个可能的实现方式中,UE状态信息可以是UE的应用发送给核心网的AF,并由AF发送给NEF,再由NEF存储在PCF中的。
PCF可以根据SMF的订阅信息等向SMF发送UE状态信息。
在一个可能的实现方式中,PCF可以根据SMF的订阅信息等向SMF发送UE状态信息。
在一个可能的实现方式中,SMF在PCF中检索UE状态信息。
在一个实施例中,所述接收来自UDM的所述UE状态信息,包括:

示例一、
在PDU会话建立过程中,SMF通过N2 SM信息携带UE状态信息传送给RAN,N2 SM信息的携带UE状态信息由AMF发送给接入网功能。
在PDU会话建立流程中,UE将UE状态信息(包括:所述UE的电池电量;所述UE的电池使用时长;所述UE的供电模式;所述UE的温度状态。)携带于PCO中发送给网络;可供网络执行相应UE状态信息订阅事件的执行和上报,或者执行XR媒体业务数据流或QoS流的策略决策和执行(例如QoS授权,PCC规则的生成和更新等)。
如图10所示,在PDU会话建立过程中UE将UE状态信息携带在PCO中发送给SMF,并由SMF发送给接入网功能的具体步骤包括:
步骤1001:UE支持向网络侧提供UE状态信息的能力,UE可以将UE状态信息携带于PDU会话建立请求消息中,e.g.PDU会话建立请求消息中的PCO中,PCO可以携带于N1 SM容器内。
步骤1002和步骤1003:AMFUE状态信息,存储在UE上下文中。选择相应SMF并发送SM上下文建立请求,SM上下文建立请求中携带步骤1001中的N1 SM容器的PCO中携带的UE状态信息。
步骤1004:SMF检查签约数据和或事件订阅,结合本地策略,确认是否可创建该会话,是否执行订阅事件上报,是否执行本地策略和QoS授权(若无PCF部署,则SMF执行静态规则激活和QoS授权)等。
例如,如果订阅了UE状态改变事件,则确认UE状态是否改变或是否满足订阅上报条件,根据订阅和上报要求,执行通知(notify)上报。
例如,确认该UE状态信息是否符合用户签约和本地策略(例如,当前UE状态是否可创建会话)。如果不符合会话创建要求,则可能拒绝该10RM业务/多模态业务的会话创建,或基于本地策略接收会话创建但不支持10RM业务/多模态业务。
步骤1007:该PDU会话使用动态PCC,则SMF执行PCF选择;否则SMF执行本地策略;该PDU会话请求支持XRM业务/多模态业务,SMF和PCF根据签约和AF提供的应用信息,生成/激活相应XRM规则/多模态数据规则,或生成/激活增强支持XRM和多模态会话的数据流PCC规则(例如关联XRM业务数据流,匹配XRM业务和多模态业务QoS,包括XRM和多模态业务数据流的GFBR,PDB,MDBV匹配等)。SMF上报UE状态信息给PCF;上报条件可以为,PCF订阅了UE状态改变事件且上报条件满足,或者签约信息或本地策略触发UE状态信息的上报。根据订阅和上 报要求,执行UE状态信息通知(UE status information notify)上报。

示例二、
UE状态信息由AF通过NEF发送到网络,存储在UDM中,由SMF/AMF订阅获取。具体步骤如图11所示,包括:
步骤1100:NF订阅UE和/或UE组数据更新的UDM通知。即MF或AMF向UDM订阅XRM事件信息,例如UE状态信息)。
步骤1101:AF通过以下至少之一项:Nnef_ParameterProvision_Create;Nnef_ParameterProvision_Update向NEF提供一个或多个参数的新增或更新。其中,参数包括:UE状态信息。这里,UE状态信息是AF从UE的应用中获取的。
这里,可以采用GPSI标识UE,采用事务参考ID(Transaction Reference ID)标识NEF和AF之间的事务请求对于Nnef_ParameterProvision_Create的情况,NEF将事务参考ID分配给Nnef_ParameterProvision_Create请求。
NEF通过检查请求者的标识符(如:AF标识符)来确定是否允许请求者执行请求的服务操作。
Nnef_ParameterProvision_Update Request的有效载荷可以包括以下至少之一项参数:
1.预期UE行为参数(Expected UE Behaviour Parameters)。这里,UE状态信息可作为预期UE行为参数传送给NEF。
2.UE状态信息。UE状态信息可以作为单独信息传送给NEF。
3.网络配置参数。
步骤1102:如果AF被NEF授权提供参数(预期UE行为参数),NEF通过Nudm_参数提供(ParameterProvision)_新增(Create)、Nudm_ParameterProvision_更新(Update)请求等消息请求创建、更新、存储和/或删除提供的参数作为订阅数据的一部分,该消息包括提供的参数(预期UE行为参数)和NEF参考ID。NEF将UE状态信息存储到UDM中。
如果AF未被授权提供参数,则NEF在步骤1102中在Nnef_ParameterProvision_Create/Update响应消息中指示失败的原因。步骤1107在这种情况下不执行。
如果NEF没有从AF接收到DNN和/或S-NSSAI,并且在5GC中根据需要配置了此类信息,则NEF根据AF标识符确定DNN和/或S-NSSAI。
步骤1103:可以通过Nudr_DM_Query从UDR中读取相应的订阅信息,以验证所需的数据更新并为此订阅者或相应AF组授权这些参数的更改。
步骤1104:如果UDM授权AF为该订阅者提供参数,则UDM将GPSI解析为SUPI,并通过Nudr_DM_Create/Update Request消息请求创建、更新或删除作为订阅数据的一部分的提供的参 数。上述该消息包括提供的参数。
如果创建了新的5G VN组,UDM应为5G VN组分配唯一的内部组ID,并将新分配的内部组ID包含在Nudr_DM_Create Request消息中。如果5G VN群组成员列表发生变化或5G VN群组数据发生变化,则UDM根据AF/NEF请求更新UE和/或UE组订阅数据。
UDR将提供的参数存储为UE和/或UE组订阅数据的一部分,并以Nudr_DM_Create/Update响应(Response)消息进行响应。
当5G VN组数据更新时,UDR通过发送Nudr_DM_Notify通知订阅的PCF。
如果AF未被授权提供参数,则UDM继续执行步骤步骤1105,在Nudm_ParameterProvision_Update响应消息中指示失败的原因,并且不执行步骤步骤1107。
UDM将接收到的参数(如:预期的UE行为参数,包括有UE状态信息)分类为AMF相关参数和SMF相关参数。UDM可以使用在步骤1102中从NEF接收到的AF标识符来将接收到的参数与特定订阅的DNN和/或S-NSSAI相关联。UDM将SMF相关参数存储在相应的会话管理订阅数据类型下。
每个参数或参数集可以与有效时间相关联。有效时间存储在UDM/UDR和每个NF中,向其提供参数(例如,在AMF或SMF中)。在有效期届满时,每个节点都会自动删除参数,无需显式信令。
1105:UDM使用Nudm_ParameterProvision_Create Response、Nudm_ParameterProvision_Update Response响应请求。如果过程失败,则采用原因值指示原因。
1106:NEF使用Nnef_ParameterProvision_Create Response、Nnef_ParameterProvision_Update Response响应请求。如果过程失败,则采用原因值指示原因。
1107:UDM通过Nudm_SDM_Notification Notify消息通知订阅的网络功能(例如,AMF,SMF)更新的UE和/或UE组订阅数据。(在步骤1104成功后才会执行此步骤)。
a)如果NF是AMF,UDM执行Nudm_SDM_Notification(SUPI或内部组标识符(Internal Group Identifier)、AMF关联的预期UE行为参数、订阅的定期注册定时器(Subscribed Periodic Registration Timer)、订阅激活时间(subscribed Active Time)等)服务操作。AMF识别是否存在重叠的参数集,并在必要时合并预期UE行为中的参数集。AMF使用接收到的参数来导出NAS参数的适当UE配置并导出核心网络辅助RAN参数。AMF可以基于参数固定指示器(Stationary indicator)或预期的UE移动轨迹(Expected UE Moving Trajectory)来确定注册区域。
b)如果NF为SMF,UDM执行Nudm_SDM_Notification(SUPI或内部组标识符(Internal Group Identifier),SMF关联的预期UE行为参数集,DNN/S-NSSAI,建议的下行数据包数(Suggested Number of Downlink Packets)等)服务操作。
SMF存储接收到的预期UE行为参数(包含有UE状态信息),并根据来自UDM的消息中包含的DNN和S-NSSAI将它们与PDU会话相关联。
SMF识别预期UE行为中是否存在重叠的参数集,并在必要时合并参数集。SMF可以使用如 下参数:
SMF可以为PDU会话导出SMF导出的CN辅助RAN信息。如PDU会话建立过程或PDU会话修改过程中所述,SMF将SMF导出的CN辅助RAN信息提供给AMF。
预期UE行为参数表征了一个UE或一个UE组的预期行为。这些UE行为参数的集合可以通过NEF提供,以作为UE数据的一部分进行存储。
UE状态信息获取后存储在UDM中;SMF或AMF通过订阅UDM事件(UE状态信息事件)进行订阅。
预期UE行为参数,例如UE状态信息,可以在UDM内分别存储为AMF相关的预期UE行为参数(UE级别),和SMF相关的预期UE行为参数(PDU级别),(即UE级别信息,存储为AMF相关预期UE行为参数;PDU级别信息,存储为SMF相关预期UE行为参数)
AMF从UDM中检索AMF相关的预期UE行为参数,这些参数可能与PDU会话和SMS传输有关。
SMF从UDM检索特定PDU会话的SMF关联的预期UE行为参数。
预期UE行为参数具体内容可以如表1所示。
示例三、
SMF通过UE 5G会话管理核心网能力(UE 5GSM Core Network Capability)获取UE状态信息的场景如下:
在PDU会话建立流程中,将UE状态信息,作为UE 5GSM Core Network Capability,提供给网络;可供网络执行相应UE状态信息订阅事件的执行和上报,或者执行XRM业务数据流或QoS流的策略决策和执行(例如QoS授权,PCC规则的生成和更新等)。
如图10所示,在PDU会话建立过程中UE将UE状态信息携带在PDU会话建立请求消息中,e.g.PDU会话建立请求消息中,e.g.在5GSM Core Network Capability中发送给SMF,并由SMF发送给接入网功能的具体步骤包括:
步骤1001:UE发送NAS消息给AMF,发起UE请求的PDU会话建立流程。N1 SM容器中携带会话创建请求,请求消息中携带UE 5GSM Core Network Capability,UE 5GSM Core Network Capability中包括UE状态信息,告知网络E状态信息。
步骤1002和步骤1003:AMF将UE状态信息,存储在UE上下文中。选择相应SMF并发送SM上下文建立请求,SM上下文建立请求中携带步骤1001中的N1 SM容器的5GSM Core Network Capability中携带的UE状态信息。。
步骤1004:SMF检查签约数据和或事件订阅,结合本地策略,确认是否可创建该会话,是否执行订阅事件上报,是否执行本地策略和QoS授权(若无PCF部署,则SMF执行静态规则激活和QoS授权)等。
例如,如果订阅了UE状态改变事件,则确认UE状态是否改变或是否满足订阅上报条件,根据订阅和上报要求,执行通知(notify)上报。
例如,确认该UE状态信息是否符合用户签约和本地策略(例如,当前UE状态是否可创建会话)。如果不符合会话创建要求,则可能拒绝该XRM业务/多模态业务的会话创建,或基于本地策略接收会话创建但不支持XRM业务/多模态业务。
步骤1004:基于SMF决策返回创建SM上下文相应消息,或更新响应消息;如果拒绝会话创建,则携带相应的拒绝原因值;可选地,如果拒绝支持XRM业务/多模态业务,携带相应原因值,指示5GC不支持XRM业务/多模态业务。
步骤1007:该PDU会话使用动态PCC,则SMF执行PCF选择;否则SMF执行本地策略;该PDU会话请求支持XRM业务/多模态业务,SMF和PCF根据签约和AF提供的应用信息,生成/激活相应XRM规则/多模态数据规则,或生成/激活增强支持XRM和多模态会话的数据流PCC规则(例如关联XRM业务数据流,匹配XRM业务和多模态业务QoS,包括XRM和多模态业务数据流的GFBR,PDB,MDBV匹配等)。SMF上报UE状态信息给PCF;上报条件可以为,PCF订阅了UE状态改变事件且上报条件满足,或者签约信息或本地策略触发UE状态信息的上报。根据订阅和上报要求,执行UE状态信息通知(UE status information notify)上报。
步骤1011和1012:UE状态信息通过N2 SM信息传送给AMF,并由AMF转送到RAN。以执行上行或下行数据流的QoS映射和传输,来更好地匹配XR媒体业务流量特性和能耗管理。
