技术领域
本公开涉及通信应用的技术领域,尤其涉及一种信息传输方法及网络设备。
背景技术
下一代(Next Gen)网络中,用户设备(User Equipment,UE,也称为终端)通过分组数据单元(Packet Data Unit,PDU)会话进行数据传输,每个UE附着到网络后可以建立多条PDU会话。每个PDU会话中可以传输多个不同服务质量(Quality of Service,QoS)要求的数据流,称为QoS流。在PDU会话建立过程中,会话管理功能(Session Management Function,SMF)实体会为每个PDU会话选择一个或者多个用户面锚点(User Plane Function,UPF),用户数据通过UE传输到基站,并由基站传输到UPF从而传输到外部数据网络。
每个QoS流具有一个5G QoS标识符(5QI),用于代表这个QoS流的QoS特征。5QI可以是标准化的值,也可以是网络动态分配的非标准化的值。每个标准化的5QI取值对应于特定的优先级、时延要求和误码率要求,其中时延要求代表从UE到UPF的传输时延,包括对从UE到基站的空口传输时延与基站到UPF的基础网络传输时延的总和的要求。对于一个5QI取值,基础网络传输时延一般认为是一个确定的值,例如对于标准化的5QI取值1,标准规定基础网络传输时延为20ms,对于标准化的5QI取值84,标准规定基础网络传输时延为5ms,对于标准化的5QI取值80,标准规定基础网络传输时延为2ms。核心网制定了5QI的要求后发送到基站,基站将5QI对应的时延要求减去基础网络传输时延得到空口传输时延要求,根据空口传输时延 进行空口资源调度。
PDU会话建立之后,UPF与基站之间的实际传输时延是确定的,相关技术中会出现分组控制功能(Packet Control Function,PCF)实体根据应用的要求及运营商配置等因素确定的5QI与上述实际的基础网络传输时延相违背的情况,从而造成网络的不稳定性。

为使本领域技术人员能够更好地理解本公开实施例,下面先对本公开实施例可应用的一种网络系统进行如下说明。
如图1所示,Next Gen网络架构如下,其中,UPF为用户面锚点,AMF和SMF为控制面网络节点,AMF负责移动性管理,并与UE和接入网(Access Network,AN)相连,该接入网可具体为基站,PCF负责策略控制。SMF为会话管理功能,与UPF相连接,负责管理UE与网络之间建立的PDU会话。 当一个PDU会话建立时,SMF为这个会话选定UPF。
每个PDU会话中可以传输多个不同QoS要求的数据流,称为QoS流。在PDU会话建立过程中,SMF会为每个PDU会话选择一个或者多个UPF,用户数据通过UE传输到基站,并由基站传输到UPF从而传输到外部数据网络。
每个QoS流具有一个5QI,用于代表这个QoS流的QoS特征。5QI可以是标准化的值,也可以是网络动态分配的非标准化的值。
标准化的5QI的值及其所代表的QoS特征如表1所示。
Figure PCTCN2019111835-appb-000001
表1
假设一个PDU会话的UPF与基站之间的基础网络实际传输时延是20ms,因为分组控制功能(Packet Control Function,PCF)实体不了解SMF为一个PDU会话所选择的UPF与UE所接入基站之间的基础网络实际传输时延,例如如果PCF根据应用的要求及运营商配置等因素确定的5QI为标准化5QI,取值为84,基站根据标准化的要求用30ms传输时延要求减去标准规定的基础网络传输时延5ms,得到25ms的空口传输时延要求,基站根据这个25ms的时延要求对这个QoS流的数据包进行调度,因为基站与UPF之间的实际传输时延是20ms,则会造成大量数据包的实际传输时延超过该5QI的传输时延要求。
本公开实施例为避免为QoS流分配的5QI的传输时延要求与该PDU会话的UPF与基站之间的实际传输时延相违背的情况的发生,提供了一种信息传输方法。图2为本公开实施例的信息传输方法的流程示意图,如图2所示,本公开实施例提供了一种信息传输方法,应用于会话管理功能SMF实体,包括:
步骤201:获取分组控制功能PCF实体发送的服务质量QoS参数,所述服务质量QoS参数包括QoS等级标识;
其中,所述QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,所述基础网络实际传输时延为基站与用户面锚点UPF之间的实际传输时延。
上述QoS等级标识可具体为5QI。
这里,上述基础网络实际传输时延可以具体是SMF在为分组数据单元PDU会话选择用户面锚点UPF后,上报给PCF的。
本公开实施例的信息传输方法,SMF获取分组控制功能PCF实体发送的服务质量QoS参数,该QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,使得PCF分配的QoS等级标识对应的基础网络传输需求时延能够满足基础网络实际传输时延,增加了网络的稳定性。
进一步地,所述服务质量QoS参数还包括:
与所述QoS等级标识对应的QoS特征值,所述QoS特征值包括基础网 络传输需求时延。
本公开实施例中,在QoS等级标识对应的取值为标准化取值时,该QoS等级标识对应一基础网络传输需求时延。在QoS等级标识对应的取值为非标准化取值时,该服务质量QoS参数还包括与所述QoS等级标识对应的QoS特征值,所述QoS特征值包括基础网络传输需求时延。
进一步地,所述获取分组控制功能PCF发送的服务质量QoS参数之前,还包括:
在为分组数据单元PDU会话选择用户面锚点UPF后,将基站与所述UPF之间的基础网络实际传输时延信息发送给所述PCF实体。
上述所述基础网络实际传输时延信息包括:
基站与UPF之间的基础网络实际传输时延、UPF标识和数据网络接入标识DNAI中的至少一项。
在PDU会话建立过程中,SMF在为这个PDU会话选择了UPF之后,SMF将基站与UPF之间的基础网络实际传输时延相关信息,具体可以是基站与UPF之间的基础网络实际传输时延,或者UPF标识,或者数据网络接入标识DNAI等信息)汇报给PCF,PCF可以根据从SMF获得的基础网络实际传输时延信息进行PCC规则中QoS等级标识(5QI)的分配,保证PCC规则中的QoS等级标识所对应的基础网络传输需求时延与该PDU会话的基站与UPF之间的基础网络实际传输时延相符合。
这里,SMF在为PDU会话选择UPF后,将上述基础网络实际传输时延信息发送给PCF实体,以使PCF实体了解该基础网络实际传输信息,进而使得分配的QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,增加了网络的稳定性。
进一步地,上述获取分组控制功能PCF实体发送的服务质量QoS参数之后,还包括:
通过接入和移动管理功能AMF向基站发送QoS流的QoS控制信息;
其中,所述QoS控制信息包括QoS等级标识、所述QoS等级标识对应的传输需求时延以及所述QoS等级标识对应的基础网络传输需求时延;
或者,所述QoS控制信息包括QoS等级标识以及与所述QoS等级标识 对应的空口传输时延。
本公开实施例中,SMF通过AMF的透传,向基站提供QoS流的QoS控制信息。具体的,该QoS控制信息包括QoS等级标识,如5QI,在该QoS等级标识对应的取值为非标准化取值时,该QoS控制信息还包括:所述QoS等级标识对应的传输需求时延以及所述QoS等级标识对应的基础网络传输需求时延,或者,该QoS控制信息还包括:与所述QoS等级标识对应的空口传输时延。
需要说明的是,上述QoS控制信息中所述QoS等级标识对应的基础网络传输需求时延,可以是SMF从PCF获取的,也可以是SMF自身确定的基础网络实际传输时延。
进一步地,上述获取分组控制功能PCF实体发送的服务质量QoS参数之后,还包括:
获取所述PCF实体发送的策略控制和计费PCC规则;
在所述PCC规则中的QoS等级标识对应的基础网络传输需求时延小于所述基础网络实际传输时延的情况下,为所述PDU会话插入新的UPF,并根据所述新的UPF对所述PDU会话中的数据流进行传输;
其中,所述新的UPF与基站之间的基础网络实际传输时延小于或者等于所述PCC规则中的QoS等级标识对应的基础网络传输需求时延。
本公开实施例中,PCF在SMF为一个PDU会话进行UPF选择或者UPF的重新选择时,已经从SMF获得了基础网络实际传输时延信息,之后当有新业务发生时,PCF从应用实体AF收到新的业务请求,如果业务请求中的QoS等级标识对应的基础网络传输需求时延与对应的PDU会话的基础网络实际传输时延不符合,PCF可以拒绝AF请求。或者PCF根据业务请求发送PCC规则给SMF,SMF根据PCC规则中的QoS等级标识(5QI)判断当前PDU会话的基础网络实际传输时延无法满足该5QI,则为该PDU会话插入新的UPF进行相应数据流的路由。
下面结合具体的实施例来对本公开实施例的信息传输方法进行说明。
实施例一:
如图3所示,该信息传输方法,包括:
步骤301:SMF为一个PDU会话选择UPF。
该步骤可以发生在一个PDU会话建立过程中,或者是一个PDU会话建立成功之后SMF重新选择UPF或者为这个PDU会话插入新的UPF的过程中。
步骤302:SMF选择UPF之后,将选择的UPF与基站之间的基础网络实际传输时延信息发送给PCF。
上述基础网络实际传输时延信息具体可以是基站与UPF之间的基础网络实际传输时延的取值或者范围,也可以是UPF标识或者数据网络接入标识DNAI等可以使PCF推断出基础网络实际传输时延的信息。
步骤303,PCF根据基础网络实际传输时延信息进行PCC规则中QoS等级标识的分配。
这里,根据基础网络实际传输时延信息进行PCC规则中QoS等级标识的分配,以保证PCC规则中的QoS等级标识所对应的基础网络传输需求时延与该PDU会话的基站与UPF之间的基础网络实际传输时延相符合,即所述QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延。
例如,如果该PDU会话中基站与UPF之间的基础网络实际传输时延为10ms,PCF则不可以分配取值84的标准化5QI,因为取值84的标准化5QI在标准中规定UE到UPF传输需求时延是30ms,其中,基础网络传输需求时延为5ms,基站根据标准化的要求计算出空口传输时延要求为25ms,基站会根据这个25ms的时延要求对这个QoS流的数据包进行调度,但是因为基站与UPF之间的实际传输时延是10ms,则会造成大量数据包在UE和UPF之间的实际传输时延达到25ms+10ms=35ms,超出了该5QI的30ms传输需求时延。但是如果PCF分配取值1的标准化5QI则是可以的,因为取值1的标准化5QI在在标准中规定UE到UPF传输需求时延是100ms,其中基础网络传输需求时延为20ms,基站根据标准化的要求计算出空口传输时延要求为80ms,基站会根据这个80ms的时延要求对这个QoS流的数据包进行调度,因为基站与UPF之间的实际传输时延是10ms,数据包在UE和UPF之间的实际传输时延最多达到80ms+10ms=90ms,不会超出该5QI的100ms传输时延要求。
如果PCF分配的5QI为非标准化取值,PCF在向SMF提供该非标准化5QI取值对应的QoS特征值时,还可以提供该5QI所对应的基础网络传输需 求时延,该基础网络传输需求时延与PDU会话的基站与UPF之间的基础网络实际传输时延相符合,例如提供的基础网络传输需求时延可以是一个不小于基础网络实际传输时延的数值。
步骤304,SMF与选定的UPF交互,建立或者修改对于这个PDU会话的N4接口会话,向UPF提供了相应QoS流的控制信息。
步骤305,SMF通过AMF的透传,向基站提供N2接口会话管理信息。
其中,该N2接口会话管理信息包括相应QoS流的QoS控制信息,QoS控制信息中包括5QI信息,如果5QI是非标准化的5QI值,QoS控制信息中还包括这个5QI对应的传输需求时延及基础网络传输需求时延,基础网络传输需求时延可以是在步骤3中SMF从PCF获得的,也可以是SMF确定的基站和UPF之间的基础网络实际传输时延,或者SMF也可以直接在QoS控制信息中包括这个5QI对应的空口传输时延。
本公开实施例中,基站根据获得的QoS控制信息进行相应的资源调度。基站需要根据收到的5QI计算空口传输要求时延。如果5QI是标准化的5QI值,基站根据这个5QI值的对应的标准规定的传输需求时延减去标准规定的基础网络传输需求时延得到空口传输需求时延。如果5QI是非标准化的5QI值,基站根据从SMF收到的传输需求时延要求减去从SMF收到的基础网络传输需求时延得到空口传输需求时延,或者基站直接从SMF发送的QoS控制信息中得到这个5QI对应的空口传输需求时延。
本公开实施例的信息传输方法,SMF在为PDU会话选择UPF后,将上述基础网络实际传输时延信息发送给PCF实体,以使PCF实体了解该基础网络实际传输信息,进而使得分配的QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,增加了网络的稳定性。
实施例二:
如图4所示,该信息传输方法,包括:
步骤401,SMF为一个PDU会话选择UPF之后,将选择的UPF与基站之间的基础网络实际传输时延信息发送给PCF。
该基础网络实际传输时延信息具体可以是基站与UPF之间的基础网络实际传输时延的取值或者范围,也可以是UPF标识或者数据网络接入标识 DNAI等可以使PCF推断出基础网络实际传输时延的信息。
步骤402,当有新业务发生时,PCF从AF收到新的业务请求,该业务请求中包括业务所需要的QoS需求。
步骤403,如果业务请求中的QoS需求与对应的PDU会话的基础网络实际传输时延不符合,PCF可以拒绝AF请求。
例如业务请求中的QoS需求要求传输时延为5ms,而PCF从SMF获得的该PDU会话的基站和UPF之间的基础网络实际传输时延已经是10ms,则无法通过当前UPF进行满足该业务的QoS需求的传输。
步骤404,根据业务需求和运营商策略制定符合业务需求的PCC规则,并将PCC规则发送给SMF。
该PCC规则包括相应的5QI,该PCC规则中的5QI与当前基站与UPF之间的基础网络实际传输时延不符合。例如虽然SMF已经上报当前PDU会话的基站和UPF之间的基础网络实际传输时延是10ms,PCF依然发送包含标准化取值85的5QI,标准化取值85的5QI在标准中规定UE到UPF传输要求是5ms,其中,基础网络传输时延为1ms,或者PCF发送包含非标准化取值的5QI,PCF在向SMF提供该非标准化5QI取值对应的QoS特征值时,还可以提供该5QI所对应的基础网络传输需求时延,该基础网络传输需求时延与当前基站与UPF之间的基础网络实际传输时延不符合,例如提供的基础网络传输需求时延是一个小于当前基础网络实际传输时延的数值。
需要说明的是,本公开实施例中在具体执行过程中仅选择上述步骤403和上述步骤404中的一个步骤。
步骤405,SMF根据PCC规则中的5QI判断当前PDU会话的基础网络实际传输时延无法满足该5QI,则选择一个新的可以满足该QoS传输时延要求的UPF,为该PDU会话插入新的UPF进行相应数据流的路由。
步骤406,SMF与选定的新的UPF交互,建立或者修改对于这个PDU会话的N4接口会话,向UPF提供了相应QoS流的控制信息。
步骤407,SMF通过AMF的透传,向基站提供N2接口会话管理信息。
该N2接口会话管理信息包括相应QoS流的QoS控制信息,QoS控制信息中包括5QI信息,如果5QI是非标准化的5QI值,QoS控制信息中还包括 这个5QI对应的传输需求时延及基础网络传输需求时延,基础网络传输需求时延可以是在步骤3中SMF从PCF获得的,也可以是SMF确定的基站和UPF之间的基础网络实际传输时延,或者SMF也可以直接在QoS控制信息中包括这个5QI对应的空口传输时延。
本公开实施例中,基站根据获得的QoS控制信息进行相应的资源调度。基站需要根据收到的5QI计算空口传输要求时延。如果5QI是标准化的5QI值,基站根据这个5QI值的对应的标准规定的传输需求时延减去标准规定的基础网络传输需求时延得到空口传输需求时延。如果5QI是非标准化的5QI值,基站根据从SMF收到的传输需求时延要求减去从SMF收到的基础网络传输需求时延得到空口传输需求时延,或者基站直接从SMF发送的QoS控制信息中得到这个5QI对应的空口传输需求时延。
本公开实施例的信息传输方法,PCF在SMF为一个PDU会话进行UPF选择或者UPF的重新选择时,已经从SMF获得了基础网络实际传输时延信息,之后当有新业务发生时,PCF从应用实体AF收到新的业务请求,如果业务请求中的QoS等级标识对应的基础网络传输需求时延与对应的PDU会话的基础网络实际传输时延不符合,PCF可以拒绝AF请求。或者PCF根据业务请求发送PCC规则给SMF,SMF根据PCC规则中的QoS等级标识(5QI)判断当前PDU会话的基础网络实际传输时延无法满足该5QI,则为该PDU会话插入新的UPF进行相应数据流的路由。
如图5所示,本公开实施例还提供了一种信息传输方法,应用于分组控制功能PCF实体,包括:
步骤501:向会话管理功能SMF实体发送服务质量QoS参数,所述服务质量QoS参数包括QoS等级标识;
其中,所述QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,所述基础网络实际传输时延为基站与用户面锚点UPF之间的实际传输时延。
上述QoS等级标识可具体为5QI。
这里,上述基础网络实际传输时延可以具体是SMF在为分组数据单元PDU会话选择用户面锚点UPF后,上报给PCF的。
本公开实施例的信息传输方法,PCF将包含QoS等级标识的QoS参数发送给SMF,该QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,使得PCF分配的QoS等级标识对应的基础网络传输需求时延能够满足基础网络实际传输时延,增加了网络的稳定性。
进一步地,所述向会话管理功能SMF实体发送服务质量QoS参数之前,还包括:
获取会话管理功能SMF实体发送的基站与UPF之间的基础网络实际传输时延信息。
上述所述基础网络实际传输时延信息包括:
基站与UPF之间的基础网络实际传输时延、UPF标识和数据网络接入标识DNAI中的至少一项。

这里,SMF在为PDU会话选择UPF后,将上述基础网络实际传输时延信息发送给PCF实体,以使PCF实体了解该基础网络实际传输信息,进而使得分配的QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,增加了网络的稳定性。
进一步地,上述向会话管理功能SMF实体发送服务质量QoS参数,包括:
在根据所述基础网络实际传输时延分配的QoS等级标识的取值为标准化取值时,将所述QoS等级标识发送至SMF实体;
在根据所述基础网络实际传输时延分配的QoS等级标识的取值为非标准化取值时,分配一QoS特征值,并将所述QoS等级标识和所述QoS特征值发送至SMF实体;
其中,所述QoS特征值包括基础网络传输需求时延,在所述QoS等级标识的取值为标准化取值时,所述QoS等级标识对应一基础网络传输需求时延。
进一步地,所述向会话管理功能SMF实体发送服务质量QoS参数之后,还包括:
在接收到新的业务请求时,若所述新的业务请求对应的基础网络传输需求时延小于所述基础网络实际传输时延信息对应的时延,则拒绝所述业务请求,或者,将所述新的业务请求对应的PCC规则发送给SMF,所述PCC规则包括所述新的业务请求对应的基础网络传输需求时延。
本公开实施例中,PCF在SMF为一个PDU会话进行UPF选择或者UPF的重新选择时,已经从SMF获得了基础网络实际传输时延信息,之后当有新业务发生时,PCF从应用实体AF收到新的业务请求,如果业务请求中的QoS等级标识对应的基础网络传输需求时延与对应的PDU会话的基础网络实际传输时延不符合,PCF可以拒绝AF请求。或者PCF根据业务请求发送PCC规则给SMF,SMF根据PCC规则中的QoS等级标识(5QI)判断当前PDU会话的基础网络实际传输时延无法满足该5QI,则为该PDU会话插入新的UPF进行相应数据流的路由。
本公开实施例的信息传输方法,PCF将包含QoS等级标识的QoS参数发送给SMF,该QoS参数中的QoS等级标识对应的基础网络传输需求时延大于或者等于基础网络实际传输时延,使得PCF分配的QoS等级标识对应的基础网络传输需求时延能够满足基础网络实际传输时延,增加了网络的稳定性。
