1. A core network comprising:
a first apparatus comprising: at least one processor; and at least one memory storing instructions of a network analytics and data function (NWADF) that, when executed by the at least one processor, cause the first apparatus at least to perform:
collecting, from a first one or more network functions (NFs), one or more actual metric values for one or more quality of service metrics associated with an application session of a user equipment, wherein a respective actual metric value of the one or more actual metric values for a respective quality of service metric of the one or more quality of service metrics comprises a value of the respective quality of service metric;
determining a quality of experience value associated with the application session of the user equipment based on the one or more actual metric values for the one or more quality of service metrics associated with the application session of the user equipment, wherein the quality of experience value is based on an aggregate score comprising a sum of respective values corresponding to the one or more values associated with the one or more quality of service metrics for the application session of the user equipment; and
sending the quality of experience value to a second network function (NF); and
a second apparatus comprising: at least one processor; and at least one memory storing instructions of the network function that, when executed by the at least one processor of the second apparatus, cause the second apparatus at least to perform:
receiving the quality of experience value; and
adjusting one or more network parameters based on the quality of experience value.
