图2示出了本申请实施例的用于传输数据的方法200的示意性框图。图2中所示的终端设备可以是如图1所示的终端设备,图2中所示的SMF设备可以是如图1所示的核心网设备。该方法200包括以下部分或全部内容:
S210,终端设备向会话管理功能SMF设备发送第一协议数据单元PDU会话的建立请求消息,该第一PDU会话的建立请求消息中携带至少一个用于建立PDU会话的参数的参数值列表和/或参数值组合列表。
具体地,当终端设备请求建立一个协议数据单元(Protocol Data Unit,PDU)会话(session)时,终端设备可以向SMF设备发送非接入层(Non-Access Stratum,NAS)消息,该NAS消息中可以携带待建立的PDU会话的标识(Identity,ID),也可以携带至少一个用于建立该PDU会话的参数的参数值列表和/或参数值组合列表。SMF设备在接收到参数值列表和/或参数值组合列表之后,可以按照该参数值列表和/或参数值组合列表进行PDU会话的建立。
可选地,在本申请实施例中,该建立PDU会话的参数例如可以是:无线接入技术(Radio Access Technology,RAT)的类型、会话和业务连续性模式Session and Service Continuity,SSC)、单网络切片辅助信息(Single-Network Slice Selection Assistance Information,S-NSSAI)和数据网络名称(Data NetworkName,DNN)中的至少一种。还可以是其他可能的参数,例如分流类型等,本申请实施例不限于此。
具体地,该参数值列表可以如表1所示。
表1
RAT接入类型 3gpp接入
会话和业务连续性模式 SSC-1
单网络切片辅助选择信息 S-NSSAI-1.S-NSSAI-2
DNN DNN-1,DNN-2,DNN3
应理解,该参数值列表中的某个参数可以有多个值,并且该多个值可以具有优先级。例如,表1中的S-NSSAI包括S-NSSAI-1和S-NSSAI-2,其中S-NSSAI-1的优先级高于S-NSSAI-2,也就是说,SMF设备在接收到该参数值列表之后,可以首先选择S-NSSAI-1进行PDU会话的建立,若说该S-NSSAI-1不满足建立要求,SMF设备可以选择S-NSSAI-1进行PDU会话的建立,直到该参数值列表中的S-NSSAI的所有值均不满足建立要求为止。
可选地,该参数值列表中的某个参数的多个值也可以不具有优先级,例如,SMF设备在接收到该参数值列表之后,SMF设备可以从S-NSSAI的多个值中先选择一个值进行PDU会话的建立,如果不满足要求,SMF设备可以重新再选择一个值进行PDU会话的建立,直到选择的参数值满足PDU会话的建立要求或者直到终端设备发送的该参数的多个值均不满足要求为止。
具体地,该参数值组合列表可以如表2所示。
表2
组合1 组合2 组合3
RAT接入类型 3gpp接入 3gpp接入 非3gpp接入
会话和业务连续性模式 SSC-1 / SSC-2
网络切片辅助选择信息 S-NSSAI-1 S-NSSAI-1 /
DNN DNN-1 DNN-2 DNN-3
应理解,该参数值组合列表中的某个参数值组合可以包括至少一个参数中每个参数的一个值,该参数值组合列表中的多个参数值组合可以包括相同的参数,也可以包括不同参数,或者包括的参数种类不同。该多个参数值组合也可以具有优先级。例如,表2中的组合1的优先级高于组合2。也就是说,SMF设备在接收到该参数值组合列表之后,可以首先选择组合1进行PDU会话的建立,若说该组合1不满足建立要求,SMF设备可以选择组合2进行PDU会话的建立,直到该参数值组合列表中的所有参数值组合均不满足建立要求为止。
因此,本申请实施例的用于传输数据的方法,终端设备通过向SMF设备发送PDU会话的参数值列表和/或参数值组合列表,有利于提高PDU会话建立成功的概率。
进一步地,该RAT的类型可以包括以下接入技术中的至少一种:新无线NR、长期演进LTE、全球移动通讯GSM、码分多址CDMA、通用分组无线业务GPRS、无线局域网WLAN和卫星接入。该RAT的类型还可以包括以下接入技术中的至少一种:第三代合作伙伴计划3GPP和非3GPP。该RAT的类型可以是上述列举的各种接入技术中的任意组合。
可选地,在本申请实施例中,该方法还包括:该终端设备接收该SMF设备发送的回复消息,该回复消息携带该第一PDU会话建立不成功的原因值。
若SMF设备建立该PDU会话不成功时,SMF设备可以向终端设备回复一个回复消息,并且在该回复消息中可以携带该PDU会话建立不成功的原因值。终端设备在接收到该原因值之后,可以做一些相应的调整。
进一步地,该原因值用于指示该至少一个用于建立PDU会话的参数中第一参数的优先级列表中的值均不满足建立要求。
若SMF设备将终端设备上报的某个参数的所有值都尝试了一遍,并且该参数的每个值都不满足PDU会话的建立要求,那么SMF设备可以直接向终端设备发送回复消息,指示是由于该参数的值不满足要求导致PDU会话建立失败。
进一步地,SMF设备还可以在回复消息中携带建议的导致PDU会话建立失败的参数的值,终端设备可以参考该SMF设备建议的值再次向SMF设备发起PDU会话的建立或者直接发起已建立的PDU会话的修改要求。

S310,终端设备向会话管理功能SMF设备发送第一协议数据单元PDU会话的建立请求消息;
S320,该终端设备接收该SMF设备发送的回复消息,该回复消息携带该第一PDU会话建立不成功的原因值。
具体地,当终端设备请求建立一个PDU会话时,终端设备可以向SMF设备发送NAS消息,该NAS消息中可以携带待建立的PDU会话的ID,在SMF设备接收到该NAS消息之后,可以结合一些参数进行PDU会话的建立,如果该PDU会话建立失败,那么SMF设备可以向终端设备回复一个回复消息,该回复消息可以携带该PDU会话建立失败的原因。例如,某个参数不满足要求等。
因此,本申请实施例的用于传输数据的方法,通过向终端设备反馈会话建立的情况,使得终端设备能够及时地对会话建立策略进行调整,从而有利于提高通信系统的性能。
可选地,终端设备可以在PDU会话的建立请求消息,也就是上述的NAS消息中携带建立该PDU会话所用的参数值列表或参数值组合列表,该参数例如可以是:无线接入技术(Radio Access Technology,RAT)的类型、会话和业务连续性模式、单网络切片辅助信息(Single-Network Slice Selection Assistance Information,S-NSSAI)和数据网络名称(Data Network Name,DNN)中的至少一种。还可以是其他可能的参数,例如分流类型等,本申请实施例不限于此。
可选地,在本申请实施例中,该参数值列表中的某个参数可以有多个值,并且该多个值可以具有优先级。例如,表1中的S-NSSAI包括S-NSSAI-1和S-NSSAI-2,其中S-NSSAI-1的优先级高于S-NSSAI-2,也就是说,SMF设备在接收到该参数值列表之后,可以首先选择S-NSSAI-1进行PDU会话的建立,若 说该S-NSSAI-1不满足建立要求,SMF设备可以选择S-NSSAI-1进行PDU会话的建立,直到该参数值列表中的S-NSSAI的所有值均不满足建立要求为止。
可选地,该参数值列表中的某个参数的多个值也可以不具有优先级,例如,SMF设备在接收到该参数值列表之后,SMF设备可以从S-NSSAI的多个值中先选择一个值进行PDU会话的建立,如果不满足要求,SMF设备可以重新再选择一个值进行PDU会话的建立,直到选择的参数值满足PDU会话的建立要求或者直到终端设备发送的该参数的多个值均不满足要求为止。
应理解,该参数值组合列表中的某个参数值组合可以包括至少一个参数中每个参数的一个值,该参数值组合列表中的多个参数值组合可以包括相同的参数,也可以包括不同参数,或者包括的参数种类不同。该多个参数值组合也可以具有优先级。例如,表2中的第二列的参数值组合的优先级高于第三列的参数值组合。也就是说,SMF设备在接收到该参数值组合列表之后,可以首先选择第二列的参数值组合进行PDU会话的建立,若说该第二列的参数值组合不满足建立要求,SMF设备可以选择第三列的参数值组合进行PDU会话的建立,直到该参数值组合列表中的所有参数值组合均不满足建立要求为止。
可选地,在本申请实施例中,该原因值用于指示所述参数值列表中的所述第一参数的参数值均不满足建立要求。
终端设备在该NAS消息中携带某些参数的值可以是一个,也可以是多个,如果是一个,那么SMF设备就直接根据该终端设备携带的参数值进行PDU会话的建立,如果不满足建立要求,SMF就向终端设备回复原因,也就是说终端设备携带的参数值不满足要求。终端设备进一步地可以进行调整。如果终端设备在该NAS消息中携带的某些参数的值是多个,SMF设备可以从多个值中先选择一个值进行PDU会话的建立,如果不满足要求,SMF设备可以重新再选择一个值进行PDU会话的建立,直到选择的参数值满足PDU会话的建立要求或者直到终端设备发送的该参数的多个值均不满足要求为止。若终端设备发送的一个或多个参数的每个值都不满足PDU会话的建立要求,那么SMF设备可以直接向终端设备发送回复消息,指示PDU会话建立失败。终端设备向SMF设备发送的参数值列表中的某个参数的多个值可以具有优先级,换句话说,SMF设备在接收到某个参数的优先级列表之后,可以首先选择某个参数的第一优先的值进行PDU会话的建立,若该参数值列表中没有包含第一优先级的值,或者说该第一优先级的值不满足建立要求,SMF设备可以选择第二优先级的值进行PDU会话的建立,直到该参数的值满足PDU会话的建立或者该参数的优先级列表中的所有值均不满足建立要求为止。
可选地,在本申请实施例中,该回复消息还携带该SMF设备建议的该第一参数的值。
若SMF设备建立PDU会话失败是因为一个或多个参数的值不满足建立要求,SMF设备可以向终端设备发送一个建议的该参数的值,该建议的值可以是一个,也可以是多个。
进一步地,该RAT的类型可以包括以下接入技术中的至少一种:新无线NR、长期演进LTE、全球移动通讯GSM、码分多址CDMA、通用分组无线业务GPRS、无线局域网WLAN和卫星接入。该RAT的类型还可以包括以下接入技术中的至少一种:第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)和非3GPP。该RAT的类型可以是上述列举的各种接入技术中的任意组合。
可选地,在本申请实施例中,该方法还包括:该终端设备响应于该回复消息,向该SMF设备发送第二PDU会话的建立请求消息。
具体地,终端设备在接收到SMF设备发送的回复消息之后,并且该回复消息还携带了终端设备发起的第一PDU会话建立不成功的原因值,终端设备就可以做相应地调整。例如,终端设备可以直接调整原因值所指示的参数的值。换句话说,若SMF设备拒绝的原因值是用于建立PDU会话的某个参数值不合适,那么终端设备可以在之前发起PDU会话建立的该参数的值的基础上调整,并再一次向SMF设备发起PDU会话的建立请求,尝试建立成功。
可选地,该终端设备响应于该回复消息,向该SMF设备向该SMF设备发送第二PDU会话的建立请求消息,包括:该终端设备响应于该回复消息,根据至少一个用于建立PDU会话的参数中至少一个参数的值的优先级列表,向该SMF设备发送该第二PDU会话的建立请求消息。
终端设备可以进一步地根据用于建立PDU会话的参数中至少一个参数的值进行调整。例如,终端设备可以从某个参数的多个值中先选择一个值进行PDU会话的建立,如果不满足要求,终端设备可以重新再选择一个值进行PDU会话的建立,直到选择的参数值满足PDU会话的建立要求或者直到该参数的多个值均不满足要求为止。某个参数的值也可以是具有优先级的多个值,换句话说,终端设备处可以存储有某个参数的优先级列表。终端设备在接收到SMF设备发送的回复消息之后,可以首先选择第一优先的值进行PDU会话的建立,若该优先级列表中没有包含第一优先级的值,或者说该第一优先级的值不满足建立要求,终端设备可以选择第二优先级的值进行PDU会话的建立,直到该参数的值满足PDU会话的建立或者该参数的优先级列表中的所有值均不满足建立要求为止。

图14示出了本申请实施例的用于传输数据的方法8000的示意性框图。图14中所示的终端设备可以是如图1所示的终端设备,图14中所示的网络设备可以是如图1所示的核心网设备。该方法8000包括以下部分或全部内容:
S8010,终端设备向网络设备发送第一请求消息,所述第一请求消息用于申请在第一协议数据单元PDU会话中进行N个数据流的会话建立。
S8020,所述终端设备接收所述网络设备发送的所述第一请求消息的回复消息,所述回复消息用于指示所述网络设备拒绝在所述第一PDU会话中进行所述N个数据流中的M个数据流的会话建立,N和M均为正整数,且N大于或等于M。
具体地,当终端设备申请针对多个数据流(Flow)在一个协议数据单元(Protocol Data Unit,PDU)会话中建立会话时,终端设备可以向核心网设备发送非接入层(Non-Access Stratum,NAS)消息,该NAS消息可以请求建立或修改某个PDU会话,并且该NAS消息中可以携带该PDU会话的标识(Identity,ID),核心网设备在接收到该NAS消息之后,就可以获知在哪个PDU会话中建立数据流的会话。应理解,一个终端设备可能会有多个PDU会话,本申请实施例是针对一个终端设备的多个PDU会话中的某一个PDU会话。核心网设备在接收到终端设备发送的该会话建立或修改请求之后,核心网设备可以触发接入网设备进行多个数据流在该PDU会话中建立或修改。接入网设备进而可以根据请求判断哪些数据流可以在该PDU会话中进行会话建立,那么数据流不能够在该PDU会话中进行会话建立,接入网设备进而可以向核心网设备发送一个数据流列表,该数据流列表可以是该接入网设备接受的数据流列表,也可以是接入网设备拒绝的数据流列表。核心网设备在接收到该数据流列表之后,可以向终端设备发送回复消息,告诉终端设备网络设备拒绝请求的数据流中的部分数据流,终端设备在有部分数据流被拒绝之后,就可以进行相应地调整,例如,可以调整建立该PDU会话的参数,或者换一个PDU会话重新发起被拒绝数据流的会话建立等。
因此,本申请实施例的用于传输数据的方法,通过向终端设备反馈会话建立的情况,使得终端设备能够及时地对会话建立策略进行调整,从而有利于提高通信系统的性能。
应理解,本申请实施例可以应用于5G通信系统,也就是说,本申请实施例的核心网设备可以是5G中的SMF。可选地,在会话建立过程中,SMF可以与UPF交互进行会话建立。
可选地,该回复消息携带拒绝原因值,该拒绝原因值用于指示该第一PDU会话不支持该M个数据流。
通常,网络侧可以拒绝一个或多个Flow在一个PDU会话中建立,可以是多种原因,例如,可能是PDU会话不允许、无线接入技术(Radio Access Technology,RAT)接入不允许、会话或业务连续性模式不满足、(Single-Network Slice Selection Assistance Information,S-NSSAI)错误、数据网络名称(Data Network Name,DNN)不支持和PDU会话标识不被识别。在本申请实施例中,网络侧在向终端设备发送的回复消息中可以携带原因值,具体地,网络侧可以和终端设备预先约定好用几个bit来表示上述各种原因,例如,可以用0001表示PDU会话不允许,0010表示RAT接入不允许等。其中,PDU会话不允许可以是PDU会话满了,不能在该PDU会话中添加数据流等,PDU会话不允许和PDU会话标识可以都看成是PDU会话不支持。当终端设备根据回复消息获知是由于PDU会话不支持的原因,终端设备可以对PDU会话进行适当的调整,再次向网络设备发起会话建立或修改。进而可以提高PDU会话建立成功的可能性。
可选地,该回复消息携带该M个数据流中每个数据流的标识。
进一步地,网络设备还可以通过回复消息向终端设备指示是哪些数据流被网络侧拒绝了,例如,可以在该回复消息中携带网络设备接受的数据流列表,终端设备可以根据接受的数据流列表进一步地可以确定出来哪些数据流被拒绝了。也可以直接在回复消息中携带网络设备拒绝的数据流列表。数据流列表可以包括多个数据流的标识。
终端设备在获知是哪些数据流被拒绝了之后,终端设备可以针对性的对这些被拒绝的数据流进行会话调整。终端设备也可以不用知道是哪些数据流被拒绝了,一旦获知拒绝原因,那么终端设备可以对所有的数据流进行会话调整。
可选地,该方法还包括:该终端设备响应于该回复消息,向该网络设备发送第二请求消息,该第二请求消息用于申请在第二PDU会话中进行该M个数据流中的至少一个数据流的会话建立。
可选地,该第一请求消息携带该第一PDU会话的标识,该第二请求消息携带该第二PDU会话的标识,该第二PDU会话为调整该第一PDU会话的标识之后的该第一PDU会话。
可选地,该终端设备响应于该回复消息之前,该方法还包括:该终端设备根据该M个数据流,调整非该第一PDU会话的该第二PDU会话的建立参数。
由上述可知,终端设备在获知被拒绝的数据流列表,以及拒绝原因是PDU会话不支持之后,终端设备可以对该数据流的会话建立进行调整。例如,若终端设备知道是由于前一次PDU会话的标识不被本地网络识别,那么终端设备可以产生一个新的标识,再次使用前一次PDU会话的内容对拒绝的数据流进行会话建立。具体地,若本地网络识别PDU会话标识1~100,而前一次的PDU会话的标识为101,那么本地网络是无法识别该PDU会话标识的,网络侧可以告诉终端设备该PDU会话标识不被识别,那么终端设备可以产生一个新的PDU会话标识在1~100之间,重新采用该PDU会话发起会 话建立或修改请求,并且在该请求中携带新产生的PDU会话标识。再例如,若终端设备知道是由于前一次PDU会话不允许被拒绝的数据流,终端设备可以将该被拒绝的数据流捆绑到另外一个PDU会话中,再次发起PDU会话建立。具体地,终端设备可以修改另外一个PDU会话的建立参数,将被拒绝的数据流与该PDU会话进行关联。
可选地,该回复消息携带该第二PDU会话的标识。
具体地,网络设备一旦判断出来是因为PDU会话不支持造成一些数据流被拒绝,网络设备可以向终端设备发送建议的PDU会话,例如,网络设备可以在回复消息中直接携带建议的PDU会话的标识。或者网络设备判断出来是由于PDU会话的标识不被识别,网络设备可以向终端设备建议的PDU会话标识。总之,网络设备可以向终端设备发送与拒绝原因值对应的各种参数的建议值。本申请实施例不限于此。
下面将结合图15详细介绍一下本申请实施例的用于传输数据的方法9000的流程图。该方法是以5G通信系统为例进行描述的,该方法9000包括以下或全部内容:
S9001,UE向SMF发送第一PDU会话建立或修改请求,该NAS消息携带该第一PDU会话的标识。

图17示出了本申请实施例的用于传输数据的方法20的示意性框图。如图17所示,该方法20包括以下部分内容或全部内容:
S21,终端设备根据用户设备路由选择策略URSP中至少一个规则中每个规则的标识,分别获取该至少一个规则。
S22,该终端设备根据该至少一个规则,分别向网络设备发起与该至少一个规则一一对应的至少一个协议数据单元PDU会话的建立或修改。
具体地,在5G中,引入了用户设备路由选择策略(UE Route Selection Policy,URSP)的概念,URSP策略规定了UE对于不同数据流的路由策略。其中,每一个终端设备只有一个URSP,每一个URSP中可以有多种规则,终端设备可以基于每一个规则发起一个PDU会话建立。具体地,终端设备可以基于某个规则中的一个或多个参数发起一个PDU会话建立或修改。例如,该一个或多个参数可以是接入RAT、会话或业务连续性、网络切片或者分流等。该规则中的参数可以由核心网测得,在终端设备进行注册过程中发送给终端设备,终端设备据此来发起会话的建立或修改流程。在本申请实施例中,可以引入规则标识,使得终端设备可以根据规则标识来获取某一规则,而不再是网络设备一次性将所有规则下发给终端设备,减轻了网络设备的压力,并且提高了通信灵活性。
可选地,该至少一个规则为多个规则,该终端设备根据该多个规则,分别向网络设备发起与该多个规则一一对应的多个协议数据单元PDU会话的建立或修改,包括:该终端设备根据该多个规则的优先级,依次向该网络设备发起该多个PDU会话的建立或修改。
具体地,在本申请实施例中,该URSP中的多个规则可以引入优先级概念,也就是说终端设备可以优先基于某种规则向网络设备发起与该规则对应的PDU会话的建立或修改。终端设备也可以将多个规则进行分类,将每一类规则进行优先级排序,对于同一类的规则内部发起的PDU会话可以不用排序,也就是说可以任意次序发起PDU会话。
可选地,可以由每个规则的标识来表征每个规则的优先等级。例如,终端设备一旦获得规则#1,终端设备可以认为该规则#1的优先等级最高。
可选地,该至少一个规则中的第一规则包括以下参数中的至少一种参数:无线接入技术RAT、会话和业务连续性模式、单网络切片辅助信息S-NSSAI、分流类型、数据网络名称DNN和数据流过滤器。
应理解,这里是以第一规则为了进行描述的,在URSP中的每一个规则都可以包括上述各种参数的任意组合,并且上述各种参数仅仅只是示意性说明,本申请实施例并不限于此。
可选地,该至少一种参数中的第一参数包括表征优先级的多个值,该终端设备根据该第一规则,向网络设备发起第一协议数据单元PDU会话的建立或修改,包括:该终端设备根据该多个值的优先级,向该网络设备发起第一PDU会话的建立或修改。
举例来说,第一规则可以包括接入RAT、会话和业务连续性模式以及单网络切片辅助信息S-NSSAI,并且接入RAT的值为第三代合作伙伴项目(3rd Generation Partnership Project,3GPP)接入(access)和无线局域网(Wireless Local Area Networks,WLAN)access。会话和业务连续性模式包括模式3和模式2,S-NSSAI包括S-NSSAI-a和S-NSSAI-b。可以将各个参数的值进行优先级排序,例如,接入RAT可以优先使用3GPP access,S-NSSAI可以优先使用S-NSSAI-a,会话和业务连续性模式可以优先使用模式3等。一旦网络设备反馈某一个参数的值不合适,那么终端设备可以调整为其他值。终端设备可以在第一次发起PDU会话建立或修改时,随机选择与该PDU会话对应的规则中某一参数的值。终端设备也可以直接选择优先级较高的某一参数的值,来提高PDU会话建立成功的可能性。若终端设备在第一次发起PDU会话建立或修改时是随机选择的某一参数的值,在网络设备由于该参数不满足要求而拒绝该PDU会话请求时,终端设备可以选择该参数的优先级更高的值再次发起该PDU会话请求。
可选地,该终端设备根据该至少一个规则中的第一规则,向网络设备发起第一协议数据单元PDU会话的建立或修改,包括:该终端设备根据该第一规则,向该网络设备发送第一请求消息,该第一请求消息用于请求该网络设备在该第一PDU会话中进行N个数据流的会话建立;在该终端设备根据该第一规则,向该网络设备发起第一PDU会话的建立或修改之后,该方法还包括:该终端设备接收该网络设备发送的该第一请求消息的回复消息,该回复消息用于指示该网络设备拒绝在该第一PDU会话中进行该N个数据流中的M个数据流的会话建立,N和M均为正整数,N大于或等于M。
可选地,该回复消息携带拒绝原因值,该拒绝原因值用于指示以下情况中的至少一种情况:PDU会话不支持、RAT接入不允许、会话或业务连续性模式不满足、S-NSSAI错误、DNN不支持和PDU会话标识不被识别。
通常,网络侧可以拒绝一个或多个Flow在一个PDU会话中建立,可以是多种原因,例如,可能是PDU会话不允许、RAT接入不允许、会话或业务连续性模式不满足、S-NSSAI错误、DNN不支持等URSP中与该PDU会话对应的规则中的参数不满足要求,也可以是PDU会话标识不被识别。在本申请实施例中,网络侧在向终端设备发送的回复消息中可以携带原因值,具体地,网络侧可以和终端设备预先约定好用几个bit来表示上述各种原因,例如,可以用0001表示PDU会话不允许,0010表 示RAT接入不允许等。终端设备一旦获知是URSP中对应规则中的某个参数不满足要求时,终端设备可以对该参数的值进行调整。
可选地,该方法还包括:该终端设备响应于该回复消息,调整与该拒绝原因值对应的该第一规则中的参数的值;该终端设备根据调整后的该第一规则,向该网络设备发送第二请求消息,该第二请求消息用于请求该网络设备在第一PDU会话中进行该M个数据流中的至少一个数据流的会话建立。
可选地,与该拒绝原因值对应的该第一规则的参数包括表征优先级的多个值,该终端设备响应于该回复消息,调整与该拒绝原因值对应的该第一规则的参数的值,包括:该终端设备响应于该回复消息,将与该拒绝原因值对应的该第一URSP的参数的值调整为优先级高于前一次发起第一PDU会话建立的值。
可选地,该回复消息携带该网络设备建议的与该拒绝原因值对应的该第一规则的参数的值,该终端设备响应于该回复消息,调整与该拒绝原因值对应的该第一URSP的参数的值,包括:该终端设备将与该拒绝原因值对应的该第一规则的参数的值调整为该网络设备建议的与该拒绝原因值对应的该第一规则的参数的值。
也就是说,终端设备在接收到回复消息后,如果网络设备在回复消息中携带了建议值,则根据建议值进行修改,如果没有携带建议值,则与拒绝原因值对应的规则中的参数可以按照参数的优先级进行调整。例如,如果网络设备回复的是接入RAT接入不满足,终端设备可以选择优先级更高的RAT接入再次发起PDU会话建立。如果网络设备回复的是接入RAT接入不满足,并且在该回复中携带了建议RAT接入为3GPP access,则终端设备可以直接根据3GPP access再次发起PDU会话建立。
可选地,该方法还包括:该终端设备接收该网络设备发送的该URSP中除该至少一个规则中第一规则外的第二规则以及该第一规则的标识;该终端设备根据第一规则的标识,获取该第一规则,包括:该终端设备在建立与该第二规则对应的第二PDU会话之后,根据该第一规则的标识,通过用户面获取该第一规则,或该终端设备根据该第一规则的标识,触发该网络设备通过控制面将该第一规则下发。

可选地,该方法还包括:该终端设备接收服务器的标识;该终端设备在建立与该第二规则对应的第二PDU会话之后,根据该第一规则的标识,通过用户面获取该第一规则,包括:该终端设备在建立与该第二规则对应的第二PDU会话之后,根据该第一规则的标识和该服务器的标识,通过用户面获取该第一规则。
可选地,该第二规则的优先级高于该第一规则的优先级。
在本申请实施例中,为了减轻网络压力,并且在URSP策略过大的情况下,PCF可能无法通过一条信令消息完全下发给终端设备,那么PCF可以通过控制面分批次向终端设备下发URSP中的多个规则,例如,可以将多个规则进行分组,每条消息下发一组规则,或者也可以对该多个规则进行优先级排序主动分批次下发,优先级高的可以先下发,终端设备还可以在每次接收完一批规则之后,向PCF发送要求的规则的标识,具体地,若PCF首次向终端设备下发规则1和规则2,终端设备可以向PCF反馈规则3和规则4的标识,使得PCF再次向终端设备发送规则3和规则4。
PCF也可以是先向终端设备发送一部分规则,并携带另外一部分规则的标识,在终端设备根据一部分规则建立好用户面之后,终端设备可以根据另外一部分规则的标识在用户面来获取。进一步地,PCF还可以向终端设备下发存储另外一部分规则的服务器的标识,终端设备在根据一部分规则建立好用户面之后,就可以根据另外一部分规则的标识在用户面相应的服务器中获取另外一部分规则。
通过分批次获取URSP策略,可以有效地降低网络压力,提高通信灵活性。
可选地,终端设备根据用户设备路由选择策略URSP中至少一个规则中每个规则的标识,分别获取该至少一个规则,包括:在该终端设备进行网络注册的过程中,该终端设备根据该至少一个规则中每个规则的标识,获取该至少一个规则。
