除非特别说明，否则，本公开中的“第一”“第二”等描述用来区分不同的对象，并不用来表示大小或时序等含义。
经研究发现，背景技术的URLLC网络切片性能测量相关技术，并不准确。例如，服务1000个用户的URLLC网络切片和服务1个用户的URLLC网络切片具有相同的端到端时延信息，按照相关技术，会得出这两个URLLC网络切片具有相同的性能的结论，但这并不准确。
本公开实施例通过确定URLLC网络切片的负荷信息，并基于URLLC网络切片的负荷信息与端到端时延信息的比例信息，确定URLLC网络切片的性能，使得URLLC网络切片性能测量更加准确。
图1示出本公开一些实施例的5G网络架构及其接口的示意图。
如图1所示，5G网络包括接入网(Access Network，AN)、核心网和数据网(Data Network，DN)。用户设备(User Equipment，UE)通过接入网接入5G网络。核心网设备例如包括用户面功能(User Plane Function，UPF)、接入和移动管理功能(Access and Mobility Management Function，AMF)、会话管理功能(Session Management Function，SMF)、中间会话管理功能实体(Intermediate-SMF，I-SMF)等。UPF可以进一步细分为：作为下行链路分类器(Uplink Classifier)的UPF和作为PDU(Protocol Data Unit，协议数据单元)会话锚(PDU session anchor)的UPF。UE和AMF之间是N1接口。AN和AMF之间是N2接口。AN和UPF之间是N3接口。UPF和I-SMF之间是N4接口。UPF和I-SMF之间 是N4接口。UPF和DN之间是N6接口。作为下行链路分类器的UPF与作为PDU会话锚的UPF之间的N9接口。SMF和I-SMF之间是N16a接口。

在一些实施例中，第一加权系数是1，第二加权系数是1。
在另一些实施例中，第一加权系数是1，第二加权系数是0。
可理解的，第一加权系数和第二加权系数的数值并不限于所举示例。
此外，URLLC网络切片在UPF N3接口上接收和发送的第一数据量相关信息的类型和URLLC网络切片在UPF N9接口上接收和发送的第二数据量相关信息的类型应该一致。例如，统计URLLC网络切片在UPF N3接口上接收和发送的数据量，并统计URLLC网络切片在UPF N9接口上接收和发送的数据量。又例如，统计URLLC网络切片在UPF N3接口上接收和发送的数据包个数，并统计URLLC网络切片在UPF N9接口上接收和发送的数据包个数。
其中，前述提及的数据量的计算方法为：数据包个数×数据包大小＝数据量。
在步骤220，获取URLLC网络切片的端到端时延信息。
在一些实施例中，获取URLLC网络切片的端到端时延信息包括：将URLLC网络切 片的上行端到端时延和下行端到端时延进行求和运算，得到URLLC网络切片的端到端时延信息。其中，网络切片端到端时延的上行时延和下行时延的计算公式，可以参考3GPP TS 28.554 6.3.1.8节，这里不再赘述。
在步骤230，基于URLLC网络切片的负荷信息与端到端时延信息的比例信息，确定URLLC网络切片的性能。
例如，将URLLC网络切片的负荷信息与端到端时延信息的比例信息，作为衡量URLLC网络切片的性能优劣的标准。比例越大，URLLC网络切片的性能越优。
URLLC网络切片的性能的计算公式如下：
Figure PCTCN2021133556-appb-000001
其中：
UsefulOutput UPF,N3表示统计的URLLC网络切片在UPF N3接口上接收和发送的第一数据量相关信息；
UsefulOutput UPF,N9表示统计的URLLC网络切片在UPF N9接口上接收和发送的第二数据量相关信息；
w N3和w N9分别表示UsefulOutput UPF,N3和UsefulOutput UPF,N9的加权系数，即前述的第一加权系数和第二加权系数。w N3大于0，w N9可以等于或大于0。
network slice mean delay表示URLLC网络切片的端到端时延信息。
UsefulOutput UPF,N3＝UsefulOutput UPF,N3,UL+UsefulOutput UPF,N3,DL
其中：
UsefulOutput UPF,N3,UL表示第一数据量相关信息中的上行接收部分，
UsefulOutput UPF,N3,DL表示第一数据量相关信息中的上行发送部分。
UsefulUutput UPF,N3,UL和UsefulOutput UPF,N3,DL可以通过如下两种测量方式中的某一种得到：
第一种：UPF在N3接口上接收到的UL GTP PDUs的数据量和发送的DL GTP PDUs的数据量。UL表示上行链路(Uplink)。GTP表示GPRS隧道协议(GPRS Tunneling Protocol)。GPRS表示通用无线分组业务(General packet radio service)。DL表示下行链路(Downlink)。
第二种：UPF在N3接口上接收到的UL GTP PDUs的数据包的个数和发送的DL GTP PDUs的数据包的个数。
UsefulOutput UPF,N9＝UsefulOutput UPF,N9,UL+UsefulOutput UPF,N9,DL
其中：
UsefulOutput UPF,N9,UL表示第二数据量相关信息中的上行接收部分，
UsefulOutput UPF,N9,DL表示第二数据量相关信息中的上行发送部分。
UsefulOutput UPF,N9,UL和UsefulOutput UPF,N9,DL可以通过如下两种测量方式中的某一种得到：
第一种：UPF在N9接口上接收到的UL GTP PDUs的数据量和发送的DL GTP PDUs的数据量；
第二种：UPF在N9接口上接收到的UL GTP PDUs的数据量和发送的DL GTP PDUs的数据包的个数。
需要说明的是：N3和N9上测量的数据量相关信息的类型需要一致，也即均采用数据量或均采用数据包的个数。根据URLLC业务的特点，如果存在大量小数据包的特点，可以采用数据包个数的数据量统计方法，如果存在大数据量的特点，可以采用数据量的统计方法。
