下面对本申请实施例提供的URSP规则优化方法中涉及的一些概念和/或术语进行解释说明。
1、URSP规则
URSP规则是3GPP协议中定义的一种终端(例如用户设备(user equipment,UE))选择和/或建立PDU会话的策略,终端根据URSP规则,可以将应用的流量匹配到特定的PDU会话。
示例性地,当终端中的某个应用有流量想要发送到服务器端的时候,该应用可以向终端发送应用的流
量特征,包括但不限于目的网际互联协议(Internet protocol,IP)地址、全限定域名(Fully Qualified Domain Name,FQDN)等,然后终端根据应用的流量特征逐个匹配终端的URSP规则。其中,在URSP规则中,所规定的流量特征包括以下流量描述符(traffic descriptor):
1)应用描述符(application descriptors):主要包括操作系统(operating system,OS)标识和操作系统应用标识(OS application identifier,OSAPPID);
2)IP描述符(IP descriptors):目的IP三元组(IP地址或IPv6网络前缀、端口号、IP以上协议的协议ID);
3)域名描述符(domain descriptors):用作域名匹配条件的FQDN或正则表达式,主要以FQDN为主;
4)非IP描述符(non-IP descriptors):非IP流量的目的信息的描述符;
5)数据网名称(data network name,DNN):这与应用提供的DNN信息相匹配,用于描述应用流量访问或者连接的数据网;
6)连接能力(connection capabilities):这与应用在请求具有某些能力的网络连接时提供的信息相匹配,类似“IP多媒体子系统(IP multimedia subsystem,IMS)”,“多媒体消息服务(multimedia messaging service,MMS),例如彩信”和“internet”等。
在应用向终端发送流量特征为一个IP描述符(例如,目的IP三元组)的情况下,该IP描述符表示应用的流量需要发给目的IP=10.1.1.1且端口号为80的一个PDU会话,如果终端的URSP规则中存在该流量描述符,则说明应用的流量特征与某个URSP规则匹配。
在应用的流量特征与URSP规则匹配之后,下一步需要选择发送应用的流量的PDU会话。一般来说,一个流量描述符下包括多个路由选择描述符(route selection descriptor,RSD),每个RSD代表一个PDU会话的一组属性或者参数。当应用的流量匹配到目的IP=10.1.1.1且端口号为80的这一组流量描述符时,这一组流量描述符下包括如下RSD(仅举例说明):
1)RSD优先级(RSD precedence)=1:单网络切片选择辅助信息(single network slice selection assistance information,S-NSSAI)-a,非3GPP接入(non-3GPP access);
2)RSD precedence=2:S-NSSAI-a,3GPP接入(3GPP access),DNN=Internet,会话和服务连续性(session and service continuity,SSC)模式=3。

2、网络数据分析网元(network data analytics function,NWDAF)
目前,在3GPP协议中,引入NWDAF来进行一些智能化的分析。NWDAF具有一定的智能分析功能,通过采集一些数据,并使用内置的算法和分析能力进行分析得到结果,提供给5G核心网网元以执行一些操作优化或者统计分析。
示例性地,NWDAF能够提供一种观测服务体验分析功能,通过采集终端访问某个服务器的服务质量(quality of service,QoS)信息,例如上行速率或下行速率、丢包率等,输出一个统计信息,该统计信息包括终端访问该服务器的用户体验情况;或者,NWDAF可以根据终端访问该服务器的历史体验情况进行预测,例如,在未来某个时间段的某个区域内,如果该终端访问该服务器,那么该终端可能获取的用户体验情况(例如QoS情况)如何。
通常,对于NWDAF所能提供的分析内容和/或预测内容,以分析标识(analytic ID)来区分,通过向NWDAF发送不同的分析标识以及一些参数,NWDAF即可提供对应的分析结果和/或预测结果。例如,若analytic ID=Service Experience,则NWDAF提供观测服务体验分析。因此,只要获取NWDAF服务的网元,在请求分析或预测的时候输入analytic ID,那么NWDAF就可以提供对应的分析结果和/或预测结果。目前NWDAF能够提供的analytic ID所对应的分析或预测结果,如表1所示。

本申请实施例提供一种URSP规则优化方法,如图5所示,该方法应用于第三通信设备,本申请实施例提供的URSP规则优化方法包括下述的步骤501和步骤502。
步骤501、第三通信设备从第一通信设备接收第四消息。
本申请实施例中,上述第四消息包含终端的第一URSP规则。
步骤502、第三通信设备基于第一URSP规则,对第一URSP规则执行情况进行评估。
可选地,本申请实施例中,在上述步骤502之后,本申请实施例提供的URSP规则优化方法还包括下述的步骤503。
步骤503、第三通信设备向第一通信设备发送异常指示信息。
其中,上述异常指示信息指示第一URSP规则执行异常。

可选地,本申请实施例中,上述步骤502具体可以通过下述的步骤502a和步骤502b实现。
步骤502a、第三通信设备向第四通信设备发送第八消息。
本申请实施例中,上述第八消息包括目标PDU会话标识。上述第八消息用于:第四通信设备在目标PDU会话标识所对应的目标PDU会话中,对第一URSP规则执行情况进行评估。
其中,上述目标PDU会话为不应存在目标应用的流量的PDU会话,该目标应用的流量为终端根据第一URSP规则进行PDU会话匹配的流量。
可选地,本申请实施例中,第三通信设备可以根据第一URSP规则,确定当前终端的哪些PDU会话中不应出现目标应用的流量,即确定出目标PDU会话,以向第四通信设备发送包括目标PDU会话标识的第八消息。
步骤502b、第三通信设备接收第四通信设备发送的第九消息。
本申请实施例中,上述第九消息用于指示第一URSP规则执行异常。
本申请实施例中,第三通信设备可以向第四通信设备发送第八消息,以使得第四通信设备对第一URSP规则执行情况进行评估,第四通信设备在确定第一URSP规则执行异常的情况下,向第三通信设备发送第九消息,以指示第一URSP规则执行异常,然后第三通信设备向第一通信设备发送异常指示信息,从而第一通信设备可以对第一URSP规则进行重评估。
需要说明的是,相关技术中,通常是在每个PDU会话中检测目标应用的流量,在哪个PDU会话中检测到目标应用的流量,就说明该PDU会话的属性或参数所对应的URSP规则是终端所使用的URSP规则。相比于在每个PDU会话中检测目标应用的流量,本申请实施例中,仅检测不应存在目标应用的流量的PDU会话,一旦检测出目标应用的流量,就说明终端错误使用或者未正确使用URSP规则,可以避免相关技术中需要检测每个PDU会话导致检测过程较为复杂的问题,从而提高了检测终端的URSP规则的效率。
比如,对于某个应用流量,该应用流量通过第一URSP规则匹配后,肯定不会匹配到PDU会话1上(该应用流量的Traffic Descriptor中的RSD未包括PDU会话1所对应的会话参数,即RSD描述的PDU会话参数与PDU会话1所对应的会话参数不一致)。那么,网络侧设备可以在承载UE的PDU会话1的UPF中,配置数据包检测规则(packet detection rule,PDR),去检测该应用流量。假如在这个PDU会话1中检测到了该应用流量,这就说明该该应用流量被匹配到了不该匹配的PDU会话上,则认定终端错误使用了第一URSP规则,或者,第一URSP规则出现了误用。
可选地,本申请实施例中,上述第八消息还包括:PDR,该PDR用于第四通信设备对第一URSP规则执行情况进行评估。
可选地,本申请实施例中,上述PDR可以为第三通信设备根据IP描述符生成的。该IP描述符可以为第三通信设备根据第一URSP规则中的流量描述符映射得到的,也可以为第三通信设备从第一通信设备接收到的。
可选地,本申请实施例中,一种实现方式中,在上述步骤502a之前,本申请实施例提供的URSP规则优化方法还包括下述的步骤504。
步骤504、第三通信设备将第一URSP规则中的第二流量描述符,映射成第二IP描述符。
其中,上述PDR为根据第二IP描述符所生成的PDR。

可选地,本申请实施例中,另一种实现方式中,上述第四消息还包括:第一IP描述符。其中,上述PDR为根据第一IP描述符所生成的PDR。
本申请实施例中,通过引入一种新的映射方式,即将第一URSP规则中的非IP描述符映射成IP描述符,第三通信设备可以基于该IP描述符对第一URSP规则执行情况进行评估,从而提高了检测终端的URSP规则的效率。
本申请实施例中,只有IP描述符(包含目的IP三元组)才可以直接用于PDR的生成。其他的描述符,比如应用描述符,域名描述符,数据网名称,连接能力等,都需要通过这个映射,转换成对应的IP描述符,才可以用于生成PDR。
本申请实施例提供一种URSP规则优化方法,如图6所示,该方法应用于第四通信设备,本申请实施例提供的URSP规则优化方法包括下述的步骤601至步骤603。

可选地,本申请实施例中,上述第九消息用于指示:在目标PDU会话中检测出目标应用的流量。
本申请实施例中,第四通信设备可以从第三通信设备接收第八消息,并在目标PDU会话标识所对应的目标PDU会话中,对第一URSP规则执行情况进行评估,在在目标PDU会话中检测出目标应用的流量的情况下,向第三通信设备发送第九消息,以指示第一URSP规则执行异常。
需要说明的是,相关技术中,通常是在每个PDU会话中检测目标应用的流量,在哪个PDU会话中检测到目标应用的流量,就说明该PDU会话的属性或参数所对应的URSP规则是终端所使用的URSP规则。相比于在每个PDU会话中检测目标应用的流量,本申请实施例中,仅检测不应存在目标应用的流量的PDU会话,一旦检测出目标应用的流量,就说明终端错误使用或者未正确使用URSP规则,可以避免相关技术中需要检测每个PDU会话导致检测过程较为复杂的问题,从而提高了检测终端的URSP规则的效率。
可选地,本申请实施例中,上述第八消息还包括PDR。上述步骤602具体可以通过下述的步骤602a实现。
步骤602a、第四通信设备在目标PDU会话中设置PDR,并根据PDR的流量检测结果,在目标PDU会话中对第一URSP规则执行情况进行评估。
本申请实施例中,仅在不应存在目标应用的流量的PDU会话中设置PDR,一旦检测出目标应用的流量,就说明终端错误使用或者未正确使用URSP规则,从而提高了检测终端的URSP规则的效率。
