●QoS机制
为了保障传输质量,需要QoS机制。如图2所示,在移动通信网络中,为了能够传输用户面数据,需要建立一个或多个QoS流(QoS Flow)。作为通信质量的重要衡量标准,通常使用QoS参数来指示QoS流的特征,不同的QoS流对应不同的QoS参数。QoS参数可以包括但不限于:5G服务质量标识(5G QoS Identifier,5QI)、分配保留优先级(Allocation Retension Priority,ARP)、保证流比特率(Guaranteed Flow Bit Rate,GFBR)、最大流比特率(Maximum Flow Bit Rate,MFBR)、上/下行最大丢包率(UL/DL Maximum Packet Loss Rate,UL/DL MPLR)、端到端数据包时延预算(Packet Delay  Budget,PDB)、AN-PDB、包误差率(Packet Error Rate,PER)、优先等级(Priority Level)、平均窗口(Averaging Window)、资源类型(Resource Type)、最大数据突发量(Maximum Data Burst Volume,MDBV)、UE聚合最大比特率(UE Aggregate Maximum Bit Rate,UE-AMBR)、会话聚合最大比特率(Session Aggregate Maximum Bit Rate,Session-AMBR)等。
QoS参数相关的规则可以通过一个或多个不同的过滤器(Filter)来实现,每个Filter可以包含描述数据包的特征参数,并用于过滤出特定的数据包以绑定到特定的QoS流上。其中,安装在终端设备上用于绑定上行Qos流和应用数据包的规则叫做QoS规则,安装在用户面功能网元(User Plane Function,UPF)用于绑定下行QoS流和应用数据包的规则叫做数据包检测规则(Packet Detection Rule,PDR)。这里,常用的Filter包含的描述数据包的特征参数为IP五元组,即源IP地址、目标IP地址、源端口号、目标端口号和协议类型。UPF和终端设备会根据数据包的特征参数组合来形成过滤器(如图2中最左边的梯形和最右边的平行四边形代表过滤器),通过过滤器过滤在用户面传递的符合数据包的特征参数的上行或下行数据包,并将其绑定到某一个QoS流上。上行QoS流是由终端设备进行绑定的,下行QoS流是由网络侧(如UPF)进行绑定的。在QoS机制中,一个或多个QoS流可以映射到一个空口资源上进行传输,作为示例,空口资源可以是数据无线承载(Data Resource Bearer,DRB)。对于一个QoS流来说,对应一套QoS参数,接入网会根据QoS参数来建立DRB并将QoS流绑定到特定的DRB上。
QoS流由会话管理功能网元(Session Management Function,SMF)触发建立。当QoS需要调整时,终端设备和网络侧均可触发PDU会话修改流程,从而改变QoS。以终端设备为例,终端设备可以通过发送PDU会话修改请求(PDU Session Modification Request)消息来修改QoS流的QoS参数或者建立新的QoS流。也就是说,当终端设备调整QoS时,需要执行一个会话修改流程,且必须得到网络的同意。由于PDU会话修改流程这一过程需要较长时间,同时也不能保证一定可以修改成功,因此会影响应用的行为,即应用无法准确判定是否以及多久可以使用其希望的QoS,这对于很多实时性业务,比如机器学习、神经网络分析等会产生较大影响。造成QoS改变情况也有很多,作为示例,以下几种情况均可造成QoS改变:1)发生了基站切换;2)发生了网络拥塞(如用户数突然增多)3)终端设备移入或移出了特定的范围(如边缘服务器的服务范围)。
目前,QoS参数一旦配置后,除非网络侧指示或者无线资源发生变化,否则QoS参数不能改变。以下结合一种场景说明QoS参数有需求进行改变。需要说明的是,本申请实施例的技术方案不局限于以下场景,其他任何有需求改变QoS参数的场景均可以应用本申请实施例的技术方案。
参照图3,终端设备-1、终端设备-2、终端设备-3分别与服务器连接,从服务器下载模型更新数据,并将训练结果上传给服务器。终端设备-1、终端设备-2、终端设备-3在上传或下载数据时,与服务器的连接需要维持在一个理想的QoS。但是,由于空口资源受限,网络不能为三个终端设备同时保障一定的QoS参数,为此,可以采用交替保障QoS参数的方法,即终端设备-1传输数据时保障其具有较好的QoS参数(如GBR=100M),这时终端设备-2和终端设备-3可以使用较差的QoS参数(如GBR=10M),从而节省空口资源。同理,终端设备-2传输数据时保障其具有较好的QoS参数,这时终端设备-1和终端设备-3可以使用较差的QoS参数。同理,终端设备-3传输数据时保障其具有较好的QoS参数,这时终端设备-1和终端设备-2可以使用较差的QoS参数。
上述场景的一种可能的用途是用于异步联邦学习或者异步分布式学习,但不局限于此。对于上述场景中的某一个终端设备来说,该终端设备的QoS参数会根据实际传输数据的情况而改变。进一步,如果该终端设备与服务器之间是周期性传输数据,则可以引 入周期性QoS的概念,即该终端设备的QoS参数是周期性调整的。对于一些周期性较大且数据量爆发的场景,仅需要周期性保障特定的QoS参数即可,从而达到节省空口资源的目的。需要说明的是,这里的“终端设备的QoS参数”是指“终端设备与服务器之间的连接对应的QoS参数”。
为了实现QoS参数的灵活调整,提出了本申请实施例的以下技术方案。
需要说明的是,本申请实施例的技术方案可以应用于任何通信系统,包括但不限于5G系统(5GS)、6G系统(6GS)等。

作为示例,所述调整的条件为地点,也就是说,当地点条件满足时,第一设备调整第一业务数据对应的传输属性参数。这里,地点条件满足例如是:第一设备的当前位置位于指定区域,或者,第一设备的当前位置位于指定区域范围。
作为示例,所述调整的条件为负荷,也就是说,当负荷条件满足时,第一设备调整第一业务数据对应的传输属性参数。这里,负荷条件满足例如是:第一业务数据的负荷量或者第一业务数据对应的连接的负荷量大于等于第一门限,或者,第一业务数据的负 荷量或者第一业务数据对应的连接的负荷量小于等于第二门限。需要说明的是,第一业务数据对应的连接是指用于传输第一业务数据的连接,也可以理解为,将第一业务数据绑定到对应的连接上进行传输。
这里,所述调整的传输属性参数可以是QoS参数。需要说明的是,调整的QoS参数可以包括一个或者多个参数。QoS参数包括但不局限于以下至少之一:5QI、ARP、GFBR、MFBR、UL/DL MPLR、端到端PDB、AN-PDB、PER、优先等级、平均窗口、资源类型、MDBV、UE-AMBR、Session-AMBR。
在一些可选实施例中,所述第一条件信息包括以下至少之一:调整的至少一个时间点信息;调整的至少一个时间段信息;调整的周期长度信息。
作为一种情况,所述第一条件信息用于确定调整的至少一个时间点;所述第一参数信息用于确定所述至少一个时间点中每个时间点对应的需要调整的传输属性参数。基于此,所述第一设备基于所述第一条件信息和所述第一参数信息,对所述第一业务数据对应的连接的传输属性参数进行调整。
在一个示例中,参照图5-1,所述第一条件信息用于指示3个时间点,分别为时间t1,时间t2,时间t3。所述第一参数信息用于指示时间t1对应的需要调整的传输属性参数为QoS参数-1,时间t2对应的需要调整的传输属性参数为QoS参数-2,时间t3对应的需要调整的传输属性参数为QoS参数-3。第一设备获取到第一信息后,从时间t1开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-1,从时间t2开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-2,从时间t3开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-3。需要说明的是,第一业务数据对应的连接是指用于传输第一业务数据的连接,也可以理解为,将第一业务数据绑定到对应的连接上进行传输。
进一步,可选地,所述至少一个时间点在时间上具有周期性。基于此,所述第一设备基于所述第一条件信息和所述第一参数信息,对所述第一业务数据对应的连接的传输属性参数进行周期性调整。
在一个示例中,参照图5-2,图5-2与图5-1的区别在于,时间t1,时间t2,时间t3具有周期性,周期长度为T。可以理解,第n个周期内的时间t1实际是时间t1+(n-1)T,第n个周期内的时间t2实际是时间t2+(n-1)T,第n个周期内的时间t3实际是时间t3+(n-1)T。对于每个周期来说,第一设备都会进行传输属性参数的调整,具体地,第一设备在每个周期内,从时间t1开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-1,从时间t2开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-2,从时间t3开始将第一业务数据对应的连接的传输属性参数调整为QoS参数-3。

在一个示例中,参照图5-3,所述第一条件信息用于指示3个时间段,分别为时间段1,时间段2,时间段3。所述第一参数信息用于指示时间段1对应的需要调整的传输属性参数为QoS参数-1,时间段2对应的需要调整的传输属性参数为QoS参数-2,时间段3对应的需要调整的传输属性参数为QoS参数-3。第一设备获取到第一信息后,在时间段1期间将第一业务数据对应的连接传输属性参数调整为QoS参数-1,在时间段2期间将第一业务数据对应的连接传输属性参数调整为QoS参数-2,在时间段3期间将第一业务数据对应的连接传输属性参数调整为QoS参数-3。
进一步,可选地,所述至少一个时间段在时间上具有周期性。基于此,所述第一设备基于所述第一条件信息和所述第一参数信息,对所述第一业务数据对应的连接的传输属性参数进行周期性调整。
在一个示例中,参照图5-4,图5-4与图5-3的区别在于,时间段1,时间段2,时间段3具有周期性,周期长度为T。可以理解,第n个周期内的时间段1的起始时间实际是时间t1+(n-1)T,t1为第1个周期内的时间段1的起始时间;第n个周期内的时间段2的起始时间实际是时间t2+(n-1)T,t2为第1个周期内的时间段2的起始时间;第n个周期内的时间段3的起始时间实际是时间t3+(n-1)T,t3为第1个周期内的时间段3的起始时间。对于每个周期来说,第一设备都会进行传输属性参数的调整,具体地,第一设备在每个周期内,在时间段1期间将第一业务数据对应的连接传输属性参数调整为QoS参数-1,在时间段2期间将第一业务数据对应的连接传输属性参数调整为QoS参数-2,在时间段3期间将第一业务数据对应的连接传输属性参数调整为QoS参数-3。

需要说明的是,第一业务数据对应的连接是指用于传输第一业务数据的连接,也可以理解为,将第一业务数据绑定到对应的连接上进行传输。
第一设备可以根据规则确定第一业务数据对应的连接,也即确定第一业务数据与连接之间的绑定关系,将第一业务数据绑定到对应的连接上进行传输。当规则调整时,第一业务数据与连接之间的绑定关系也相应的调整,因而第一设备可以根据调整的规则调整第一业务数据对应的连接。
作为示例,在5GS中,终端设备所依据的规则称为QoS规则,终端设备可以根据QoS规则确定出第一业务数据对应的上行QoS流,将第一业务数据绑定到该上行QoS流上进行传输。UPF所依据的规则称为PDR,UPF可以根据PDR确定出第一业务数据对应的下行QoS流,将第一业务数据绑定到该下行QoS流上进行传输。
这里,所述调整的条件包括但局不限于以下至少之一:时间、地点、负荷。

在一个示例中,参照图6-1,所述第一条件信息用于指示3个时间点,分别为时间t1,时间t2,时间t3。所述第一参数信息用于指示时间t1对应的需要调整的规则为规则-1,时间t2对应的需要调整的规则为规则-2,时间t3对应的需要调整的规则为规则-3。第一设备获取到第一信息后,从时间t1开始根据规则-1将第一业务数据对应的连接调整为QoS流-1,从时间t2开始根据规则-2将第一业务数据对应的连接调整为QoS流-2,从时间t3开始根据规则-3将第一业务数据对应的连接调整为QoS流-3。
进一步,可选地,所述至少一个时间点在时间上具有周期性。基于此,所述第一设备基于所述第一条件信息和所述第二参数信息,对所述第一业务数据对应的连接进行周期性调整。
在一个示例中,参照图6-2,图6-2与图6-1的区别在于,时间t1,时间t2,时间t3具有周期性,周期长度为T。可以理解,第n个周期内的时间t1实际是时间t1+(n-1)T,第n个周期内的时间t2实际是时间t2+(n-1)T,第n个周期内的时间t3实际是时间t3+(n-1)T。对于每个周期来说,第一设备都会进行连接的调整,具体地,第一设备在每个周期内,从时间t1开始根据规则-1将第一业务数据对应的连接调整为QoS流-1,从时间t2开始根据规则-2将第一业务数据对应的连接调整为QoS流-2,从时间t3开始根据规则-3将第一业务数据对应的连接调整为QoS流-3。
作为另一种情况,所述第一条件信息用于确定调整的至少一个时间段;所述第二参数信息用于确定所述至少一个时间段中每个时间段内对应的需要调整的规则。基于此,所述第一设备基于所述第一条件信息和所述第二参数信息,对第一业务数据对应的连接进行调整。
在一个示例中,参照图6-3,所述第一条件信息用于指示3个时间段,分别为时间段1,时间段2,时间段3。所述第一参数信息用于指示时间段1对应的需要调整的规则为规则-1,时间段2对应的需要调整的规则为规则-2,时间段3对应的需要调整的规则为规则-3。第一设备获取到第一信息后,在时间段1期间根据规则-1将第一业务数据对应的连接调整为QoS流-1,在时间段2期间根据规则-2将第一业务数据对应的连接调整为QoS流-2,在时间段3期间根据规则-3将第一业务数据对应的连接调整为QoS流-3。
进一步,可选地,所述至少一个时间段在时间上具有周期性。基于此,所述第一设备基于所述第一条件信息和所述第二参数信息,对所述第一业务数据对应的连接进行周期性调整。
在一个示例中,参照图6-4,图6-4与图6-3的区别在于,时间段1,时间段2,时间段3具有周期性,周期长度为T。可以理解,第n个周期内的时间段1的起始时间实际是时间t1+(n-1)T,t1为第1个周期内的时间段1的起始时间;第n个周期内的时间段2的起始时间实际是时间t2+(n-1)T,t2为第1个周期内的时间段2的起始时间;第n个周期内的时间段3的起始时间实际是时间t3+(n-1)T,t3为第1个周期内的时间段3的起始时间。对于每个周期来说,第一设备都会进行传输属性参数的调整,具体地,第一设备在每个周期内,在时间段1期间根据规则-1将第一业务数据对应的连接调整为QoS流-1,在时间段2期间根据规则-2将第一业务数据对应的连接调整为QoS流-2,在时间段3期间根据规则-3将第一业务数据对应的连接调整为QoS流-3。

参照图7,图7是会话建立或修改的流程示意图,包括以下步骤:
步骤701:终端设备向核心网发送会话建立或修改请求消息。
这里,核心网可以是核心网控制面网元。作为示例,在5GS中,所述第一核心网网元为SMF。
步骤702:核心网向基站和/或终端设备发送会话建立或修改请求回复消息,该消息携带第一信息。

需要说明的是,作为示例,会话建立或修改请求消息可以是PDU会话建立或修改请求消息,会话建立或修改请求回复消息可以是PDU会话建立或修改请求回复消息。
本申请实施例的技术方案中,一方面,一个连接对应的传输属性参数会发生变化,可选地,例如会周期性发生变化,为此,在会话建立或修改流程中,核心网将第一信息发送给第一设备,第一设备根据第一信息对传输属性参数(如QoS参数)进行调整。需要指出的是,第一设备获取到第一信息后,可以根据第一信息自动调整传输属性参数,每次调整时不需要核心网的指示,也不需要第一设备通知核心网。
本申请实施例的技术方案中,另一方面,用于确定第一业务数据与连接之间的绑定关系的规则(如QoS规则、PDR)会发生变化,可选地,例如会周期性发生变化。由于规则的变化会导致第一业务数据与连接的绑定关系发生变化,因此也就意味着第一业务数据对应的连接发生变化,可选地,例如会周期性发生变化,为此,在会话建立或修改流程中,核心网将第一信息发送给第一设备,第一设备根据第一信息对第一业务数据的连接(如QoS流)进行调整。需要指出的是,第一设备获取到第一信息后,可以根据第一信息自动调整第一业务数据的连接,每次调整时不需要核心网的指示,也不需要第一设备通知核心网。
本申请实施例的技术方案可以为个终端设备在合适的时间段内提供高传输质量的保障,合理的利用了无线资源。此外,本申请实施例的技术方案重用现有的会话建立或修改流程来下发第一信息,对协议影响较小,易于实现。
