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,所述第一PDU会话的建立请求消息中携带N个数据流滤波器的信息,所述N个数据流滤波器的信息用于请求所述第一PDU会话能够允许传递匹配所述N个数据流滤波器数据包,N为正整数。
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数据流滤波器(Traffic Filter)的信息,该Traffic Filter信息用于向SMF设备请求该建立的PDU会话能够允许相关的Traffic Filter的数据包传递,也就是说,建立的PDU会话的服务数据流(Service Data Flow Template,SDF)模板中包含该终端设备发送的Traffic Filter的信息。SMF设备在收到该NAS消息之后,可以边建立PDU会话,边将终端设备携带的Traffic Filter绑定到该建立的PDU会话,如果该建立的PDU会话接受某些Traffic Filter,就说明被接受的匹配这些Traffic Filter的数据包允许在该建立的PDU会话中传递。
因此,本申请实施例中的用于传输数据的方法,通过在PDU会话的建立请求消息中携带Traffic Filter的信息,使得SMF设备能够获知将哪些Traffic Filter绑定在建立的PDU会话中,进而有利于提高在该PDU会话传递相关Traffic Filter数据包的成功率。
可选地,在本申请实施例中,该数据流滤波器的信息包括以下信息中的至少一种信息:应用标识、网络协议(Internet Protocol,IP)-3元组和统一资源定位符(Uniform Resource Locator,URL),该数据流滤波器的信息还可以 包括其他可能的扩展标识,本申请实施例不限于此。
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设备发送的响应消息,该响应消息携带该N个数据流滤波器中被该第一PDU会话接受或拒绝的M个数据流滤波器的信息,M为正整数。
SMF设备在建立成功终端设备请求的PDU会话之后,可以向终端设备回复终端设备携带的Traffic Filter的关联情况,例如,SMF设备可以在响应消息中携带被拒绝的Traffic Filter的信息,或者在该响应消息中携带被接受的Traffic Filter的信息。终端设备一旦获知其中一种状态的Traffic Filter,就可以得到另外一种状态的Traffic Filter。SMF设备可以部分或全部拒绝终端设备想要关联的Traffic Filter。应理解,SMF设备在向终端设备回复的被接受的或被拒绝的Traffic Filter可以只针对终端设备想要关联的Traffic Filter,也可以包括其他终端设备想要关联的Traffic Filter,本申请实施例对此不构成限定。
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响应消息,向该SMF设备发送第二PDU会话的建立请求消息,该第二PDU会话的建立请求消息中携带被该第一PDU会话拒绝的该N个数据流滤波器中除该M个数据流滤波器之外的(N-M)个数据流滤波器的信息或该M个数据流滤波器的信息,该(N-M)个数据流滤波器的信息或该M个数据流滤波器的信息用于请求该第二PDU会话能够允许传递匹配该(N-M)个数据流滤波器或该M个数据流滤波器的数据包,(N-M)为正整数。
SMF设备在向终端设备反馈那些Traffic Filter被PDU会话拒绝之后,终端设备可以再一次向SMF设备发起PDU会话的建立,请求将被拒绝的那些Traffic Filter关联到该次建立的PDU会话中。应理解,再次发起的PDU会话可以是前一次PDU会话,例如,与前一次PDU会话的ID相同,也可以是与前一次不同的PDU会话,例如,与前一次PDU会话的ID相同。
可选地,在本申请实施例中,该响应消息携带该第一PDU会话建立不成功的原因值。
若SMF设备建立该第一PDU会话不成功时,也就是终端设备想要关联的所有的Traffic Filter都没有绑定到该PDU会话中,SMF设备可以向终端设备回复一个响应消息,并且在该响应消息中可以携带该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,在本申请实施例中,该第一PDU会话的建立请求消息中携带至少一个用于建立该第一PDU会话的参数中每个参数的至少一个值,该原因值用于指示该至少一个用于建立该第一PDU会话的参数中的第一参数的该至少一个值不满足建立要求。
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,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。
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回复响应消息,指示PDU会话建立失败。终端设备向SMF设备发送的某个参数的多个值可以具有优先级的多个值,换句话说,终端设备可以向SMF设备发送某个参数的优先级列表。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,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,该响应消息还携带该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。
